The Great Canon and Great example of Repentance

Every year the Great Lent, in the Orhodox Church an important part of the Fasting time and Church faithful meeting for the Services is the reading of the so called "Great Canon" .
Canon of Repentance  was composed in the distant seventh century by a notable saint in the Church saint Andrew of Crete (Greek: Ἀνδρέας Κρήτης, c. 650 – July 4, 712 or 726 or 740), also known as Andrew of Jerusalem.
He was an 8th-century bishop, theologian, homilist, and hymnographer. He is highly venerated in our One Holy Eastern Orthodox and considered in saint in the Catholic Church as well.

His life's most important work The Great Canon prayed in singing form during every Great Lent period in the Church since then and is example for Christians for how a repentance's set stone should be set and which are the main positive and negative personages we know from the holy bible scriptures.  The Great Canon is known well and sung often by dedicated Christians even in their home in or outside of the great lent period.
The canon expresses the overall understanding of the Church through times for good and bad examples of how a man should live, if he wants to have a good life in Christ and what he should abstain and not do if he wants to accept in deed and "utilize" so to say the Salvation given by Christ on the Cross.

The Great Canon was composed by saint Adnrew in the Seventh Century ! And preserved its preserved its form and content up to this very day. 
It is  lenghtly one as it is a Church services that lasts sometimes from 1 hour 50 minutes hour or even up to 2 hours 50 hours if performed with a  Bishop or a Metropolitan. The Saint Andrews Canon is red every day in the First week during first of Great Lent divided by IV parts on Monday, Tuesday, Wednesday, Thursday.

Great Canon Content

Saint_Andrew_of_Crete-book-cover

Great Canon text consists of four parts, each divided into nine odes like any other regular church canon.
There are slight differences between the odes of the two compositions. In the Great Canon, there is a greater number of troparia (songs sung in honour of a Biblical major event, a saint veneration song or other song with content to glorify the miracles of Christ).
A common remembering part of the Canon heard is the begging "Have mercy on me, O God, have mercy on me,
At the refrain "Have mercy on me, O God, have mercy on me," a full prostration (a bow to the ground). is performed Also, some of the odes have additional refrains and troparia to the author of the canon, St. Andrew of Crete, and Saint Mary of Egypt who spend 47 years hermit life in the desert and is one of the greatest models of repentance in Christian history.

A basic distinguishing feature of the Great Canon is its extremely broad use of images and subjects taken both from the Old and New Testaments. As the Canon progresses, the congregation encounters many biblical examples of sin and repentance. The Bible (and therefore, the Canon) speaks of some individuals in history in a positive light, and about others in a negative one—the penitents are expected to emulate the positive examples of sanctity and repentance, and to learn from and avoid the negative examples of sin, fallen nature and pride. However, one of the most notable aspects of the Canon is that it attempts to potray the Biblical images in a very personal way to every penitent: the Canon is written in such form that the faithful identify themselves with many people and events found in the Bible.
Great-Canon-of-Saint-Andrew-Crete-manuscript-XII-century-Moscow

The earliest manuscript we know of attesting to the Great Canon (with a slightly different order of troparia and a shorter composition) is the Studite Triodion of the middle of the second half of the ninth century, stored in the library of the Academy of Sciences in St. Petersburg.
This manuscript has the Canon in hits original place in the services of Great Lent – at Matins of Thursday in the fifth week (when the life of St. Mary of Egypt is read). 
Only later does it also appear at Compline of the first four days of the first week.

The Canon is a soul-piercing, heartfelt lament of the righteous for his sins. The very beginning: “Where shall I begin to weep for the action of my wretched life? What first-fruit shall I offer, O Christ, in this my lamentation? (Ode 1)—attunes the soul for mourning and repentance, for the “wounding of the heart.”

The author of the Canon laments not only for himself, but for all mankind that has sinned. He recalls every transgression, every fall, from Adam to the New Testament. The majority of the Canon—eight odes—consists of Old Testament examples. St. Andrew doesn’t just recall the sins of the forefathers, but he experiences them as his own: “I have rivaled in transgression Adam the first-formed man, and I have found myself stripped naked of God” (Ode 1).

The transgressions of the forefathers become prototypes of the passions that torment a man: “Instead of the visible Eve, I have the Eve of the mind: the passionate thought in my flesh” (Ode 1). Or another example: “To whom shall I liken thee, O soul of many sins? Alas! To Cain and to Lamech. For thou hast stoned thy body to death with thine evil deeds, and killed thy mind with thy disordered longings (Ode 2: “See now, see”). Here St. Andrew follows St. Maximus the Confessor, for whom Cain is “the acquisition, the law of the flesh,” rising up against Abel, that is, the mind, according to the symbolic interpretation, and killing him. This is what St. Maximus writes: “Had Abel kept guard over himself and had he not gone out with Cain into the field, that is, into the plain of natural contemplation, before attaining dispassion, then Cain, who is and is called the law of the flesh would not have risen up and killed him” (Ad Thalassium 49).

If in the Canon St. Andrew recalls examples of Old Testament and New Testament righteousness, then it is first of all in order to reproach his soul for sloth and for sinfulness and to call it to imitation, for example: “O miserable and wicked soul, imitate the righteous and pure mind of Joseph; and do not live in wantonness, sinfully indulging thy disordered desires” (Ode 5).

The Canon is a broad historical panorama outlining the history of human sin and human righteousness, of the rejection and acceptance of God. The contents of the Canon are deeply Christ-centered, with heartfelt appeals to Christ in every ode, for example: “May the Blood from Thy side be to me a cleansing fount, and may the water that flows with it be a drink of forgiveness. May I be purified by both, O Word, anointed and refreshed, having as chrism and drink Thy words of life” (Ode 4). The only way of purification for St. Andrew is in Christ, through sobriety, feat (podvig), and all time giving and living all for God.

saint-Andrew-of-Cretes-icon

The Great Canon of St. Andrew is, undoubtedly, based on a robust Patristic foundation, with quotes from St. Meletius of Sardis, St. Ephraim of Syria, St. Gregory the Theologian, St. Gregory of Nyssa, and St. Maximus the Confessor. And the merit of St. Andrew of Crete is that he was able to synthesize their experience and imprint it into the Canon.

What is given to us in the Canon of Repentance of St. Andrew of Crete is the Biblical, ecclesiastical, truly universal experience of repentance, of the stinging of the heart, of the excruciating removal of the old, dead man and the putting on of the New Adam, in Christ Jesus, our Lord, to Whom glory is unto the ages of ages.

Fix “init: Id “ad” respawning too fast: disabled for 5 minutes” – Reload /etc/inittab changes in memory apply without rebooting Linux server

Thursday, April 15th, 2021

inittab-logo-reload-inittab-without-reboot

During my daily sysadmin tasks I've been contacted by a colleague, reporting issues with missing logs in rsyslog on a very old Redhat Server release 5.11.
Exact version is:

root@linux-server:~# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 5.11 (Tikanga)

After checking the logs, I have confirmed his finding that in reality since about more than a year logs were not produced and al I could find multiple messages in /var/log/messages reading like:

init: Id "ad" respawning too fast: disabled for 5 minutes
init: Id "ad" respawning too fast: disabled for 5 minutes
init: Id "ad" respawning too fast: disabled for 5 minutes
init: Id "ad" respawning too fast: disabled for 5 minutes
init: Id "ad" respawning too fast: disabled for 5 minutes
init: Id "ad" respawning too fast: disabled for 5 minutes
…

I've checked the status of rsyslog which seemed to be fine

root@linux-server:~# /etc/init.d/rsyslog status
rsyslogd (pid  13709) is running…

The redhat version on the system was

root@linux-server:~# rpm -qa |grep -i rsyslog
rsyslog-3.22.1-7.el5

 

root@linux-server:~# tail -n 16 /var/log/messages
Apr 15 17:21:25 linux-server init: Id "ad" respawning too fast: disabled for 5 minutes

Apr 15 18:21:39 linux-server init: Id "ad" respawning too fast: disabled for 5 minutes

 

root@linux-server:~# /etc/init.d/rsyslog status
rsyslogd (pid  13709) is running…

Since the system is so old and I've seen this message and experienced this "respawning too fast: disabled for 5 minutes" myself in the past on some old Redhat 6.0 before RHEL was born as well as on Slackware Linux. The /etc/inittab which is nowadays obsoleted in newer Linux distributions was used to keep respawing a processes which have the chance to die out for some reason. 

For those unfamiliar with inittab there is a short extract from man inittab to get idea what it is.

 

NAME
       inittab  –  format of the inittab file used by the sysv-compatible init
       process

DESCRIPTION
       The inittab file describes which processes are started  at  bootup  and
       during  normal  operation  (e.g. /etc/init.d/boot, /etc/init.d/rc, get-
       tys…).  Init(8) distinguishes multiple runlevels, each of  which  can
       have  its  own  set of processes that are started.  Valid runlevels are
       0-6 plus A, B, and C for ondemand entries.  An  entry  in  the  inittab
       file has the following format:

              id:runlevels:action:process
 

So for example the use of /etc/inittab was very handy to configure a separate TTY12 (physical console) in the text environment of Linux to log all your messages. Another good use if you had a bash / perl / python script that you wanted to respawn (resurrect itself if it does out) on OS level without adding additional software like Dan Bernstein's all famous daemontools inittab was the right thing to use. It is a pity nowadays inittab is obsoleted in modern Linux OSes but the most likely reason to remove it is if you put some broken script that overeats CPU or memory if it runs multiple times you can easily get into a hung system.

Thus the logical thing to do is to check /etc/inittab content for any strange issues with less /etc/inittab and near the end of file found the problematic process which was triggering a never ending error messages to rsyslog and the module to protect from such messages in rsyslog by values $SystemLogRateLimitInterval and $SystemLogRateLimitBurst

# configure rsyslog rate limiting
# Rate-limiting
$SystemLogRateLimitInterval 5
$SystemLogRateLimitBurst 50000

The problem causing respawning too fast: disabled for 5 minutes

Was an old version of TivSM IBM Tivoli Service Manager /opt/tivoli/tsm/client/ba/bin/dsmc, set in the past in /etc/inittab it seems some colleague after updating to a more recent version has either changed the location of dsmc binary either the architecture of old tsm itself required a record in /etc/inittab in case if for some reasons or bugs the dsmc during backup creation was dying.

root@linux-server:~# tail -8 /etc/inittab
6:2345:respawn:/sbin/mingetty tty6

# Run xdm in runlevel 5
x:5:respawn:/etc/X11/prefdm -nodaemon

#ad:2345:respawn:/opt/tivoli/tsm/client/ba/bin/dsmc sched >/dev/null 2>&1

root@linux-server:~# rpm -qa |grep -i tivsm
TIVsm-API-5.3.4-0
TIVsm-stagent-5.3.4-0
TIVsm-BA-5.3.4-0
TIVsm-API64-5.3.4-0


The logical thing to do was to check whether this binary exist at all here is the result:

root@linux-server:~$ ls -al /opt/tivoli/tsm/client/ba/bin/dsmc
ls: /opt/tivoli/tsm/client/ba/bin/dsmc: No such file or directory

Obviously someone decided to comment out the inittab support for /opt/tivoli/tsm/client/ba/bin/dsmc as the binary was not present and the dsmc backup was executed via a separate one time cron job or the service itself was configured to run continue, but forgot to reread its configuration so in the kernel memory inittab was still having the instruction to loop over the dsmc binary, since the Linux machine was not rebooted ages (1472 days) or 4.8 years time.

root@linux-server:~#  uname -a; echo; uptime
Linux linux-server2.6.18-419.el5 #1 SMP Wed Feb 22 22:40:57 EST 2017 x86_64 x86_64 x86_64 GNU/Linux

 19:04:34 up 1472 days,  5:20,  1 user,  load average: 0.12, 0.07, 0.06


So what really happens is <b>inittab</b> is trying to kind of re-run all the time dsmc process in a similar way like it would in a bash never ending loop;


while [ 1 ]; do 
/opt/tivoli/tsm/client/ba/bin/dsmc sched
done

Since the $PATH location to the binary returns 'No such file or directory' message this message floods up the rsyslog every second which triggers the LimitBurst protection of rsyslog causing rsyslog to disable completely logging for 5 minutes. The next 5 minutes when the time expires for blocking out logging due to reached limit burst.
dsmc binary sends again few ten thousand of messages for few seconds which are already waiting in a queue of rsyslog and the LimitBurst anti DDoS protection activates again. The reason for the LimitBurst is simply because if it logging is not disabled quickly the repeating message is going to fill the hard drive of the system and noone will be able to login. So rsyslog activated the good protection.

It seems noone from support colleagues, never ever noticed this init: Id "ad" respawning too fast: disabled for 5 minutes in /var/log/messages. So since the syslog was continuesly blocked by overflow of non-sense messages, systems  normal logging was interruped and respectively prevented any other meaningful error messages and warnings from the system to get properly logged  and perhaps flooed the remote rsyslog logging servers @logging-servers:514 in /etc/rsyslog.conf …


Fix to respawning too fast: disabled for 5 minutes

Very simply make /etc/inittab get reloaded in memory with:

root@linux-server:~# /sbin/init q

or with the linked telnet, which was so much used by us sys admins in the past

root@linux-server:~# /sbin/telinit q

To make the rsyslog suspension disabled of course we need to restart it again.

root@linux-server:~# /etc/init.d/rsyslog restart

root@linux-server:~# /etc/init.d/rsyslog status
rsyslogd (pid  13710) is running…

And Voila logs from services are being delivered normally via configured stuff in /etc/rsyslog.conf, to make sure this is so:

root@linux-server:~# tail -8 /var/log/messages
Apr 15 14:36:29 linux-serverinit: Id "ad" respawning too fast: disabled for 5 minutes
Apr 15 14:41:37 linux-serverinit: Id "ad" respawning too fast: disabled for 5 minutes
Apr 15 14:51:22 linux-serverinit: Id "ad" respawning too fast: disabled for 5 minutes

Apr 15 15:06:45 linux-serverinit: Id "ad" respawning too fast: disabled for 5 minutes

Configure rsyslog buffering on Linux to avoid message lost to Central Logging server

Wednesday, January 13th, 2021

rsyslog-Centralized-Logging-System-using-Rsyslog_logo

1. Rsyslog Buffering

One of the best practice about logs management is to send syslog to a central server. However, a logging system should be capable of avoiding message loss in situations where the server is not reachable. To do so, unsent data needs to be buffered at the client when central server is not available. You might have recently noticed that many servers forwarding logs messages to a central server do not have buffering functionalities activated. Thus I strongly advise you to have look to this documentation to know how to check your configuration: http://www.rsyslog.com/doc/rsyslog_reliable_forwarding.html

Rsyslog buffering with TCP/UDP configured

In rsyslog, every action runs on its own queue and each queue can be set to buffer data if the action is not ready. Of course, you must be able to detect that "the action is not ready", which means the remote server is offline. This can be detected with plain TCP syslog and RELP, but not with UDP. So you need to use either of the two. In this howto, we use plain TCP syslog.

– Version requirement

Please note that we are using rsyslog-specific features. The are required on the client, but not on the server. So the client system must run rsyslog (at least version 3.12.0), while on the server another syslogd may be running, as long as it supports plain tcp syslog.

How To Setup rsyslog buffering on Linux

First, you need to create a working directory for rsyslog. This is where it stores its queue files (should need arise). You may use any location on your local system. Next, you need to do is instruct rsyslog to use a disk queue and then configure your action. There is nothing else to do. With the following simple config file, you forward anything you receive to a remote server and have buffering applied automatically when it goes down. This must be done on the client machine.

# Example:
# $ModLoad imuxsock             # local message reception
# $WorkDirectory /rsyslog/work  # default location for work (spool) files
# $ActionQueueType LinkedList   # use asynchronous processing
# $ActionQueueFileName srvrfwd  # set file name, also enables disk mode
# $ActionResumeRetryCount -1    # infinite retries on insert failure
# $ActionQueueSaveOnShutdown on # save in-memory data if rsyslog shuts down
# *.*       @@server:port

Christ is Risen Eastern Orthodox Resurrection Paschal Greeting in Different Languages

Friday, April 24th, 2020

Resurrection-of-Christ-holy-orthodox-icon-Voskresenie-Hristovo

Happy Easter to All Orthodox Christians worldwide ! 
We are the the bright week –  this is the week after The Feast of Feasts Resurrection of Christ. This year in 2020, we Orthodox Christians celebrated this feast on 19th, 20th and 21st of April. The celebrations of the Feast of Christians and the Paschal joy continues for the whole week, so I found some time to quickly blog to share the Joy of the Resurrection of the Savior Jesus Christ who has freed all People from the Fear of the Death by Manifestating Death has been overtaken by Life Eternally.
Earlier years, I've blogged shortly on the Christ is risen in many languages. But this time I decided to extend my previous blog by adding some more details on which are the Member Churches consisting the Christ body of Holy Orthodoxy, What is the Creed of Faith (Symbol of Faith) difference Between Orthodox Christians and Roman Catholics and why we're not catholics and do celebrate Easter on a different date from Roman Catholics. Finally I will post the Paschal Greeting translated to as many languages I could find.

In the Eastern Orthodox Christian world which is the True Church of Christ consists of 15 National Churches each traced back to the Holy Apostles of Christ, each of Churches is in eucharistic Communion with the other. 

Canonical Orthodox Christ Churches as of year 2020 are the following:

1. Orthodox Church of Constantinople
2. Orthodox Church of Alexandria
3. Orthodox Church of Antiochia
4. Jerusalem Patriarchal Orthodox Church
5. Bulgarian Orthodox Church
6. Georgian Orthodox Church
7. Serbian Orthodox Church
8. Russian Orthodox Church
9. Romanian Orthodox Church
10. Orthodox Church of Cyprus (archibishopship)
11. Greek Orthodox Church
12. Albanian Orthodox Church
13. Polish Orthodox Church
14. Orthodox Church of Chech Lands and Slovakia
15. American Orthodox Church


Historically Christ Church was one before the Great Schism that was perhaps the greatest tragedy of mankind after Christ's Crucifix it occured in 1054 A.D. About this saddening events, the manuscripts and contemporary saints says with this terrible event, the whole world shaked its basis. The result of the Bulla brought by Pope's messangers in Hagia Sophia Cathedral in Constantinople in the Holy Alter of the Church putting in document of official schism and the Church of the east condeming the Western Church Cuhrch action headed by the pope due to the false Creed of faith inclusion legallized by the pope with the so called 'Filioque' word formula that changed the original agreement of Church fathers decisions on the First Ecumenical Council of Constantinople in 381 A.D. (which by the way puts Anathemas on anyone who dares to change the Creed of Faith as well change by the Popes in the well known ancient Baptism Formulas like oilment (receving the sign of the holy spirit during baptism).

The historical number of Orthodox Churche dioceses were much more numerous but with the time and the hardships this are the only ones that left as official Churches, many dioceses were destroyed by the Muslims Conquests and Roman Catholics orders like the Jesuits whose fight against orthodoxy has been severe in their attempt to make the whole world to turn to the pope, this is very well known by the many remains of Uniates around Europe, especially in nowadays Ukraine. There is a lot of nations like Chechz and Hungarians whose for many centuries confessed orthodoxy but due to the economic relations with the West and the converion of their rulers (princes / Kings) etc. to Roman Catholicism has gradually converted their Eastern Churches to Roman Catholics.

The origional Nicean Creed (Nicea-Constantinople) creed of faith reads as this:

Nicean Creed of Faith ( Agreed on 381 Anno Dommini in Emperor Constantine City of Byzantine Empire Constantinople)

We believe in one God, the Father Almighty, Maker of heaven and earth, and of all things visible and invisible.

And in one Lord Jesus Christ, the only-begotten Son of God, begotten of the Father before all worlds (æons), Light of Light, very God of very God, begotten, not made, consubstantial with the Father;

by whom all things were made;

who for us men, and for our salvation, came down from heaven, and was incarnate by the Holy Ghost and of the Virgin Mary, and was made man;

he was crucified for us under Pontius Pilate, and suffered, and was buried, and the third day he rose again, according to the Scriptures, and ascended into heaven, and sitteth on the right hand of the Father;

from thence he shall come again, with glory, to judge the quick and the dead. ;

whose kingdom shall have no end.

* And in the Holy Ghost, the Lord and Giver of life, who proceedeth from the Father, who with the Father and the Son together is worshiped and glorified, who spake by the prophets.

In one Holy Catholic and apostolic Church; we acknowledge one baptism for the remission of sins; we look for the resurrection of the dead, and the life of the world to come. Amen.

The Western Church head Bishop the Pope and local priests due to some historical regions of Spain and other parts of Western Europe's aim to fight heresies included the word Latin word Filioque in above translated text (Word which is translated as "And from the Son") in above starred line 'And in te Holy Ghost, The Lord Giver of Life who proceedeth from the Father' become 'And in the Holy Ghost, The Lord Giver of Life who proceedeth from the Father (Filioque) = and from the Son.' this was acceptable for the Eastern Churches until the moment when this Confession of Faith has been legalized for the Whole Western Church with a decree so called pope 'Bulla' with which it become the official confession of faith for the whole Catholic Church. The Eastern Church of course was following the accepted Canon rules from the first Ecumenical Council in 381 A.D. and rejected to accept the definition of the Pope at first in the Face of Saint Patriarch Photios I of Constantinople (year 810 –  893) and become official in 1054 by the rule of Pope Leo whose legates tried to claim Headship of the Pope over the whole Church and questioned the title of the Constantinople Ecumenical Patriarch Michael I Cerularius.
Along with the chages of the Creed of Faith the West, the years during centuries VII and IX centuries has already put a lot of differences in the East and West Church along doctrinal, theological, linguistic, political, and geographical lines so the split was a reflection of all this. The Latin Church was much more power hungry and more progressive for its time and authoritarian, trying to combine the Worldly power with the Spiritual one given by the line of Apostoles from Christ Ceasaris-Papism, where the Eastern Church was governed in the ancient model of the Worldly power in face of Eastern Roman empire Emperor and the Patriarch who was a governor of the Spiritual power. The schism was worsened also by the many Latins raids in the Eastern Empire Christian brothers and the sacking of Constantinople in 8-13 April year 1204. Of course both Wester and Eastern Roman Empire had an appetite for a conquest over the other and often this has lead the secular rulers on both sides to try to manipulate activities of the spiritual leaders of both to work for their interests, but the schism would never occur if the spiritual establishment of the Church which are the Holy Canons (decision of the Ecumenical Councils) were not breached by the Western Church.
One of this breaches of the Ancient canons is the Celebration of Eastern Pascha which says the Christian Pascha should never coincide with Jewish Pascha. However in the Western Church this rule was breached and nowadays The Eastern (The Day of the Resurrection of Christ) in the Roman Catholic Church (Western Church) coincides most of the years with Jewish Pascha (both Roman Catholics and the executors of Christ who never accepted him the Jews celebrate together … a sad fact).

Nowadays most of the Ancient Churches of the East together with the Eastern Orthodox Churches, who are confessing the Faith of Christ such as it was handed by the Saint Fathers has a very specific ancient way of confession of faith similar to the Creed of Faith which was a very common short ancient way to confess the faith when two Christians met it is perhaps originating from the times of the Heresies in the 1st century right after the Christ Crucifix, when the pupil of Christ used it to confirm the Glorious and unexplainable Miracle of the Resurrection of the Lord Jesus Christ from the Death in Real Body in the 3rd day from the Grave in the Cave where his body was buried.

Resurrection-of-Christ-Anastasis-Greek-orthodox-icon

The Greeting Formula is the well known in the Eastern Orthodox Churches such as in Bulgaria / Greece / Russia / Serbia etc. Christ is Risen.
On every easter Almost everyone in the Orthodox Christian Countires greats everyone else both in homes on the street at work or anywhere relatives friends and even unfamiliar people who has to do business deeds with the immersely joyful greeting.

ХРИСТОС ВОСКРЕСЕ / CHRIST IS RISEN !!!!! !!!

Then the greeted Person answers back

ВОЙСТИНУ ВОСКРЕСЕ / TRULY HE IS RISEN (INDEED HE IS RISEN) !!!!!!!!

In the Orthodox Churches, believers do greet themselves with this heartful joyful greeting for the whole 40 days after the Feast of Resurrection of Christ.

In Russia, Ukrain, Belarus and the surrounding Slavonic lands there is this tradition that the greeting is repeated 3 times as an interaction between person A and person B, for example.

Person A (3 times) greets:
ХРИСТОС ВОСКРЕСЕ = CHRIST IS RISEN !!!
Person B (3 times) answers:
ВОЙСТИНУ ВОСКРЕСЕ = TRULY HE IS RISEN !!!

How to enable HaProxy logging to a separate log /var/log/haproxy.log / prevent HAProxy duplicate messages to appear in /var/log/messages

Wednesday, February 19th, 2020

haproxy-logging-basics-how-to-log-to-separate-file-prevent-duplicate-messages-haproxy-haproxy-weblogo-squares
haproxy  logging can be managed in different form the most straight forward way is to directly use /dev/log either you can configure it to use some log management service as syslog or rsyslogd for that.

If you don't use rsyslog yet to install it: 

# apt install -y rsyslog

Then to activate logging via rsyslogd we can should add either to /etc/rsyslogd.conf or create a separte file and include it via /etc/rsyslogd.conf with following content:
 

Enable haproxy logging from rsyslogd


Log haproxy messages to separate log file you can use some of the usual syslog local0 to local7 locally used descriptors inside the conf (be aware that if you try to use some wrong value like local8, local9 as a logging facility you will get with empty haproxy.log, even though the permissions of /var/log/haproxy.log are readable and owned by haproxy user.

When logging to a local Syslog service, writing to a UNIX socket can be faster than targeting the TCP loopback address. Generally, on Linux systems, a UNIX socket listening for Syslog messages is available at /dev/log because this is where the syslog() function of the GNU C library is sending messages by default. To address UNIX socket in haproxy.cfg use:

log /dev/log local2 


If you want to log into separate log each of multiple running haproxy instances with different haproxy*.cfg add to /etc/rsyslog.conf lines like:

local2.* -/var/log/haproxylog2.log
local3.* -/var/log/haproxylog3.log


One important note to make here is since rsyslogd is used for haproxy logging you need to have enabled in rsyslogd imudp and have a UDP port listener on the machine.

E.g. somewhere in rsyslog.conf or via rsyslog include file from /etc/rsyslog.d/*.conf needs to have defined following lines:

$ModLoad imudp
$UDPServerRun 514


I prefer to use external /etc/rsyslog.d/20-haproxy.conf include file that is loaded and enabled rsyslogd via /etc/rsyslog.conf:

# vim /etc/rsyslog.d/20-haproxy.conf

$ModLoad imudp
$UDPServerRun 514​
local2.* -/var/log/haproxy2.log


It is also possible to produce different haproxy log output based on the severiy to differentiate between important and less important messages, to do so you'll need to rsyslog.conf something like:
 

# Creating separate log files based on the severity
local0.* /var/log/haproxy-traffic.log
local0.notice /var/log/haproxy-admin.log

 

Prevent Haproxy duplicate messages to appear in /var/log/messages

If you use local2 and some default rsyslog configuration then you will end up with the messages coming from haproxy towards local2 facility producing doubled simultaneous records to both your pre-defined /var/log/haproxy.log and /var/log/messages on Proxy servers that receive few thousands of simultanous connections per second.
This is a problem since doubling the log will produce too much data and on systems with smaller /var/ partition you will quickly run out of space + this haproxy requests logging to /var/log/messages makes the file quite unreadable for normal system events which are so important to track clearly what is happening on the server daily.

To prevent the haproxy duplicate messages you need to define somewhere in rsyslogd usually /etc/rsyslog.conf local2.none near line of facilities configured to log to file:

*.info;mail.none;authpriv.none;cron.none;local2.none     /var/log/messages

This configuration should work but is more rarely used as most people prefer to have haproxy log being written not directly to /dev/log which is used by other services such as syslogd / rsyslogd.

To use /dev/log to output logs from haproxy configuration in global section use config like:
 

global
        log /dev/log local2 debug
        chroot /var/lib/haproxy
        stats socket /run/haproxy/admin.sock mode 660 level admin
        stats timeout 30s
        user haproxy
        group haproxy
        daemon

The log global directive basically says, use the log line that was set in the global section for whole config till end of file. Putting a log global directive into the defaults section is equivalent to putting it into all of the subsequent proxy sections.

Using global logging rules is the most common HAProxy setup, but you can put them directly into a frontend section instead. It can be useful to have a different logging configuration as a one-off. For example, you might want to point to a different target Syslog server, use a different logging facility, or capture different severity levels depending on the use case of the backend application. 

Insetad of using /dev/log interface that is on many distributions heavily used by systemd to store / manage and distribute logs,  many haproxy server sysadmins nowdays prefer to use rsyslogd as a default logging facility that will manage haproxy logs.
Admins prefer to use some kind of mediator service to manage log writting such as rsyslogd or syslog, the reason behind might vary but perhaps most important reason is  by using rsyslogd it is possible to write logs simultaneously locally on disk and also forward logs  to a remote Logging server  running rsyslogd service.

Logging is defined in /etc/haproxy/haproxy.cfg or the respective configuration through global section but could be also configured to do a separate logging based on each of the defined Frontend Backends or default section. 
A sample exceprt from this section looks something like:

#———————————————————————
# Global settings
#———————————————————————
global
    log         127.0.0.1 local2

    chroot      /var/lib/haproxy
    pidfile     /var/run/haproxy.pid

    user        haproxy
    group       haproxy
    daemon

    # turn on stats unix socket

    server Backend_Server2 10.10.10.2 check port 18088 backup


The log directive in above config instructs HAProxy to send logs to the Syslog server listening at 127.0.0.1:514. Messages are sent with facility local2, which is one of the standard, user-defined Syslog facilities. It’s also the facility that our rsyslog configuration is expecting. You can add more than one log statement to send output to multiple Syslog servers.

Once rsyslog and haproxy logging is configured as a minumum you need to restart rsyslog (assuming that haproxy config is already properly loaded):

# systemctl restart rsyslogd.service

To make sure rsyslog reloaded successfully:

systemctl status rsyslogd.service


Restarting HAproxy

If the rsyslogd logging to 127.0.0.1 port 514 was recently added a HAProxy restart should also be run, you can do it with:
 

# /usr/sbin/haproxy -f /etc/haproxy/haproxy.cfg -D -p /var/run/haproxy.pid -sf $(cat /var/run/haproxy.pid)


Or to restart use systemctl script (if haproxy is not used in a cluster with corosync / heartbeat).

# systemctl restart haproxy.service

You can control how much information is logged by adding a Syslog level by

    log         127.0.0.1 local2 info


The accepted values are the standard syslog security level severity:

Value Severity Keyword Deprecated keywords Description Condition
0 Emergency emerg panic System is unusable A panic condition.
1 Alert alert   Action must be taken immediately A condition that should be corrected immediately, such as a corrupted system database.
2 Critical crit   Critical conditions Hard device errors.
3 Error err error Error conditions  
4 Warning warning warn Warning conditions  
5 Notice notice   Normal but significant conditions Conditions that are not error conditions, but that may require special handling.
6 Informational info   Informational messages  
7 Debug debug   Debug-level messages Messages that contain information normally of use only when debugging a program.

 

Logging only errors / timeouts / retries and errors is done with option:

Note that if the rsyslog is configured to listen on different port for some weird reason you should not forget to set the proper listen port, e.g.:
 

  log         127.0.0.1:514 local2 info

option dontlog-normal

in defaults or frontend section.

You most likely want to enable this only during certain times, such as when performing benchmarking tests.

(or log-format-sd for structured-data syslog) directive in your defaults or frontend
 

Haproxy Logging shortly explained


The type of logging you’ll see is determined by the proxy mode that you set within HAProxy. HAProxy can operate either as a Layer 4 (TCP) proxy or as Layer 7 (HTTP) proxy. TCP mode is the default. In this mode, a full-duplex connection is established between clients and servers, and no layer 7 examination will be performed. When in TCP mode, which is set by adding mode tcp, you should also add option tcplog. With this option, the log format defaults to a structure that provides useful information like Layer 4 connection details, timers, byte count and so on.

Below is example of configured logging with some explanations:

Log-format "%ci:%cp [%t] %ft %b/%s %Tw/%Tc/%Tt %B %ts %ac/%fc/%bc/%sc/%rc %sq/%bq"

haproxy-logged-fields-explained
Example of Log-Format configuration as shown above outputted of haproxy config:

Log-format "%ci:%cp [%tr] %ft %b/%s %TR/%Tw/%Tc/%Tr/%Ta %ST %B %CC %CS %tsc %ac/%fc/%bc/%sc/%rc %sq/%bq %hr %hs %{+Q}r"

haproxy_http_log_format-explained1

To understand meaning of this abbreviations you'll have to closely read  haproxy-log-format.txt. More in depth info is to be found in HTTP Log format documentation


haproxy_logging-explained

Logging HTTP request headers

HTTP request header can be logged via:
 

 http-request capture

frontend website
    bind :80
    http-request capture req.hdr(Host) len 10
    http-request capture req.hdr(User-Agent) len 100
    default_backend webservers


The log will show headers between curly braces and separated by pipe symbols. Here you can see the Host and User-Agent headers for a request:

192.168.150.1:57190 [20/Dec/2018:22:20:00.899] website~ webservers/server1 0/0/1/0/1 200 462 – – —- 1/1/0/0/0 0/0 {mywebsite.com|Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Ubuntu Chromium/71.0.3578.80 } "GET / HTTP/1.1"

 

Haproxy Stats Monitoring Web interface


Haproxy is having a simplistic stats interface which if enabled produces some general useful information like in above screenshot, through which
you can get a very basic in browser statistics and track potential issues with the proxied traffic for all configured backends / frontends incoming outgoing
network packets configured nodes experienced downtimes etc.

haproxy-statistics-report-picture

The basic configuration to make the stats interface accessible would be like pointed in above config for example to enable network listener on address
 

https://192.168.0.5:8080/stats


with hproxyuser / password config would be:

# HAProxy Monitoring Config
#———————————————————————
listen stats 192.168.0.5:8080                #Haproxy Monitoring run on port 8080
    mode http
    option httplog
    option http-server-close
    stats enable
    stats show-legends
    stats refresh 5s
    stats uri /stats                            #URL for HAProxy monitoring
    stats realm Haproxy\ Statistics
    stats auth hproxyauser:Password___          #User and Password for login to the monitoring dashboard

 

 

Sessions states and disconnect errors on new application setup

Both TCP and HTTP logs include a termination state code that tells you the way in which the TCP or HTTP session ended. It’s a two-character code. The first character reports the first event that caused the session to terminate, while the second reports the TCP or HTTP session state when it was closed.

Here are some essential termination codes to track in for in the log:
 

Here are some termination code examples most commonly to see on TCP connection establishment errors:

Two-character code    Meaning
—    Normal termination on both sides.
cD    The client did not send nor acknowledge any data and eventually timeout client expired.
SC    The server explicitly refused the TCP connection.
PC    The proxy refused to establish a connection to the server because the process’ socket limit was reached while attempting to connect.


To get all non-properly exited codes the easiest way is to just grep for anything that is different from a termination code –, like that:

tail -f /var/log/haproxy.log | grep -v ' — '


This should output in real time every TCP connection that is exiting improperly.

There’s a wide variety of reasons a connection may have been closed. Detailed information about all possible termination codes can be found in the HAProxy documentation.
To get better understanding a very useful reading to haproxy Debug errors with  is in haproxy-logging.txt in that small file are collected all the cryptic error messages codes you might find in your logs when you're first time configuring the Haproxy frontend / backend and the backend application behind.

Another useful analyze tool which can be used to analyze Layer 7 HTTP traffic is halog for more on it just google around.

Saturday, December 8th, 2012

Business or not a business entity, in the mostly globalized world it is almost inevitable to go on at least monthly basis without a need for some kind of currency convertion. Of course there are plenty of websites allowing Free Money Convertion services out there. However as I'm not a big fan of the Software as a Service (SAS). I don't like other people to be able to sniff what kind of money, amounts I'm intending to convert as well as I don't like google or other search engine to profile me how frequently I'm converting or intending to convert money. Thus today I did a quick research what kind of Free and  Open Source Software FOSS is available to do the money convertion operation custom on my own webserver or my desktop PC. Though It was not exactly what I was looking for I found a Windows Desktop Software -CConverter which is capable of convertions between mostly if not all Currencies around the world. I'm not a m$ Windows user myself, but I was glad to know a Free Software exists for the task. CConverter is definitely a piece of soft useful for Businesses and People. In future if I do my own business it would be nice to know of this little handy soft existence and I will put it in action (to save costs) and add confidentiality to my business money transaction / convertions. Below is the two screenshots of CConverter I found on the project's sourceforge website:

How to convert Adobe PDF file format to Microsoft Word DOC on MS Windows 2000 / XP / Vista / 7

Tuesday, July 24th, 2012

How to convert PDF to DOC on Microsoft Windows XP, MS Windows 7, Win Vista convert PDF to MS DOC 2003, ABBYY Covert Page
I had to convert Adobe PDF file to Microsoft Word ( .doc) file on Microsoft Windows OS for a friend. There is plenty of software available to convert PDF to DOC on Windows, as well as few web-site services claiming to convert correcly PDF to DOC. Converting PDF to DOC is easy and can be done with Open Office, however the reverse process is a real pain in the ass. I tried a dozen of free web serviecs to convert an ancient Latin writting PDF to DOC but none of them couldn’t properly convert it. Failing with the web services as a tool to convert, I’ve turned to seeking a tool that will do the trick. After trying few PDF to DOC converters which failed to produce a properly structed edittable DOC from the PDF file, I’ve come across ABBYY PDF Transformer 2.0. Abbyy PDF Transformer finally did it …

I’ve tried hard to look for a free software good PDF to DOC converter alternative for Windows but it seems as of time of writing this post there is no GPLed free software that does properly convert PDFs to MS WORD DOC ….

Using Abbyy PDF Transformer 2.0 is a piece of cake all I had to do is select the PDF file (pressing Open PDF) and then click on Convert (in right bottom corner). Below is a shot of Abby PDF transformer in action.

Color Trick Microsoft and Google use to keep their users loyal and happy unwalfully

Tuesday, June 12th, 2012

Color mind influence has been longly researched. It is researched and there are some findingings on how we people react on colors. This researches are not much known and most of them are not put on the internet (??) One model claiming to have explained how colors influence is called HBDI – Herrmann Brain Dominance Instruments.

In the picture beginning of this post, I have presented a quick "Personal Profile" of HBDI on how one think in order to determine in "which colors" one tends to think more ___

In short HBDI model claims to explain how people think in another model.
My personal view of it is it is like most science nowdays more based on faith than on a clearly conducted scientific research and facts. We know pretty well many people tried to explain how brain operates and many people give models to explain it however none of the models could grasp in completeness the complexity of human brain. Hence Businessman people who use this model in their daily life and they push it to us has put the model in action not that they know it is working but rather they believe it does .., Saying this few words as introduction I will contninue onwards to explain you about HBDI as in the business world it is considered as a "Strategic Asset" for a company success. Hence the use of richest companies of the model has a serious impact on us the common people and unknowing (uninformed) computer users.

Some of the companies who integrated the HBDI to their models we all know are of course not strangely Microsoft and Google
;;;

Below I present you a picture showing the HBDI The Whole Brain Model |||

HBDI The whole brain model

Next I show you Microsoft Windows OS worldly "infamous" flag |||

Microsoft Windows OS Flag

You can see for yourself the basic color from HBDI WHOLE brain model are integrated in the Microsoft flag, only the order of colors present and the color gamma is different;;;;

The basic colors in HBDI model to explain how human brain works is separated in 4 segments as you can see from above screenshot. There are a number of tests one can do to determine what is his exact HBDI profile, and in abstract terms in which kind of colors he prefers to think.

There are a whole "army" of people involved into this sect like philosophy (I call it philosophy as surely every model that tries to explain everything is doomed to fail it is the nature in which God created the universe so complex and he put us be part of it and not controllers of it that any Universal model trying to explain it has never succeeded so far. The HBDI has some fruits for the only reason it is believed to work well by the people with money.

As you see in the colors HBDI claims there are 4 segments corresponding to four basic colors

  • BLUE
  • YELLOW
  • GREEN
  • RED

Each of the colors is an indicator on how the person tends to think the BLUE people as HBDI practicioners (believers) calls them are —

Analytical, Fact Based, Logal, Quantitative

The YELLOW oriented people are claimed to be —

Holistic, Intuitive, Integrating, Synthesizing

The GREEN ones in model terms are interested in —

Organizing, Sequentiality, Planning, Detailizing facts

Finally the RED Ones are said to be —

Interpersonal, Feeling based, Kinesthetic, Emotional

Now as you can understand this model though it looks like promising is based on a philosophy which rejects the existing of spirit realm God Angels or good or evil. It claims everything we're are or we want to be can be achieved following the HBDI to develop your own brain.

This model as every human made model however does reject the fact that besides internal factors and brains we're put into external environment most of which we cannot control and therefore even if we try our best to have certain goals and complete them the external uncontrolled facts can be a reason to stop us to complete our goals.

Now back to my point, that Google, Microsoft and probably many other products and physical goods are heavily using the HBDI color scheme ;;;
Here is the Google Inc. Logo the color trait of HBDI is there:

Google Search Engine Logo and HBDI 4 colors embedded

For those doubting that Google Inc. and Microsoft Inc. are along the false believers of HBDI color scheme brain ideology I present below the Logo of Google Web Browser =- Google Chrome

Google Web Chrome Browser Logo 4 colors HBDI microsoft flag

It is evident 4 colors used as a main ones in the HBDI tool are present in Google Chrome just like in Microsoft Windows logo flag, the only difference is in the order of colors.
Also it is interesting the name Chrome that Google Chrome took is most likely taken from Aldous Huxley's – Brave New World (A book depicting a short future highly conditioned society) , the book story line goes around a society programmed to do the things they do.

I assume it is very likely that Google's founders Sergey Brin or some of their subordinate working for Google are very much into the idea of conditioning people just like in the book and this is most likely the reason they choose the Chrome as a title for Google's browser ,,,

The 4 Colors from HBDI yellow, green, blue, red are embedded also in the google .ico file (the little icon showing in browser URL bar), below is a screenshot of a tab where google is opened showing the .ico image:

Google Icon 4 colors Linux Debian Epiphany Browser tab screenshot

Do you remember the good old Windows XP start button, have you noticed the Windows flag embedded in it, if not let me show you;;;

Microsoft Windows XP Start Button and HBDI 4 colors scheme

But wait the Windows flag placed on the left bottom of Ms Windows-es is not only on XP it is also on Windows 3.11 cover, Winblows 98, Vista, Windows 2003, Windows 2007 and actually all the M$ operating systems ever produced since the very early days M$ become a top OS producer :::

Windows 3.11 Operating system logo flag

Microsoft Windows 95 4 colors flag and blue sky

Here is also the 4 colored (a bit like Nazi like looking) flag on M$ Win-doze 7 |||

MS Windows 7 start Menu m$ windows well known flag

Also the Microsoft Flag is positioned on the bottom left screen on purpose. It is well known fact that most of the world (except Arabic) are used to read the text from Left to Right

, therefore it is natural for our eyesight to look for the text on the left side. I just wonder why they placed the START on the bottom and not on top. It is natural we read text and books from the most top to the most bottom ,,,.,

Even Apple Computers nowdays Macs has most likely used the HBDI as the main 4 colors and some gamma from rainbow colors are present on their Classical Apple Computer logo

Old Apple Computer/s logo colors of rainbow 4 hbdi colors are there

Makes me wonder if Jobs employed the HBDI model in his company. Well what is the reason for people loving so much this rainbow colors combination. If we think for a second outside of HBDI's brainwashing ideology for what each color would stand for. Well it is simple is comes from our young years most of the people between age 2 and 50 years has been more or less exposed to the so colorful Kids Cartoons, which are all so colorfully painted. Since our very early age we've placed in us a love for colorfulness outlook (well again not all of us for example I prefer less colors, I'm sure there are plenty of people who don't like the heavy colors we see in almost everywhere around us).

The problem with this 4 colors use on purpose and all this unnatural color placing everywhere is that it is unnatural and not in good synergy with our surrounding natural environment. Therefore I personally think using a colorful color paintings on everywhere in both computer programs and the physical world plays us a bad joke and is one of the reasons so many people are on the virge to get crazy nowdays and many have already had already cracked out.

It is my firm believe more and more people should be educated on the harm of HBDI and the fact that, we're forced to 'live it' unwilfully every day by using even as "simple things" as computers and daily technology or buying food in the super market ,,,

How to show country flag, web browser type and Operating System in WordPress Comments

Wednesday, February 15th, 2012

!!! IMPORTANT UPDATE COMMENT INFO DETECTOR IS NO LONGER SUPPORTED (IS OBSOLETE) AND THE COUNTRY FLAGS AND OPERATING SYSTEM WILL BE NOT SHOWING INSTEAD,

!!!! TO MAKE THE COUNTRY FLAGS AND OS WP FUNCTIONALITY WORK AGAIN YOU WILL NEED TO INSTALL WP-USERAGENT !!!

I've come across a nice WordPress plugin that displays country flag, operating system and web browser used in each of posted comments blog comments.
Its really nice plugin, since it adds some transperancy and colorfulness to each of blog comments 😉
here is a screenshot of my blog with Comments Info Detector "in action":

Example of Comments Info Detector in Action on wordpress blog comments

Comments Info Detector as of time of writting is at stable ver 1.0.5.
The plugin installation and configuration is very easy as with most other WP plugins. To install the plugin;

1. Download and unzip Comments Info Detector

linux:/var/www/blog:# cd wp-content/plugins
linux:/var/www/blog/wp-content/plugins:# wget http://downloads.wordpress.org/plugin/comment-info-detector.zip
...
linux:/var/www/blog/wp-content/plugins:# unzip comment-info-detector.zip
...

Just for the sake of preservation of history, I've made a mirror of comments-info-detector 1.0.5 wp plugin for download here
2. Activate Comment-Info-Detector

To enable the plugin Navigate to;
Plugins -> Inactive -> Comment Info Detector (Activate)

After having enabled the plugin as a last 3rd step it has to be configured.

3. Configure comment-info-detector wp plugin

By default the plugin is disabled. To change it to enabled (configure it) by navigating to:

Settings -> Comments Info Detector

Next a a page will appear with variout fields and web forms, where stuff can be changed. Here almost all of it should be left as it is the only change should be in the drop down menus near the end of the page:

Display Country Flags Automatically (Change No to Yes)
Display Web Browsers and OS Automatically (Change No to Yes

Comments Info Detector WordPress plugin configuration Screenshot

After the two menus are set to "Yes" and pressing on Save Changes the plugin is enabled it will immediately start showing information inside each comment the GeoIP country location flag of the person who commented as well as OS type and Web Browser 🙂

Bulgaria silently signs for ACTA / Why ACTA, SOPA and PIPA are bad for our freedom

Thursday, February 2nd, 2012

r freedomYesterday silently with zero publicity, Bulgarian representatives ratified the ACTA (Trade agreement for fighting counterfeit.)
The name sounds really good, but it has not much to do with what ACTA is about, when applied to digital medias and data sharing.
The ACTA legislation has been ratified in Tokyo last week, where 22 of the European Union membership countries signed in favour of these "malicious" treaty.

The basic idea of ACTA looks tempting as it gives more freedoms to copyright holders, however if you look closely you will understand actually this copyright infringement clauses are not so in favour of us the users but mostly in favour of multinational corporations.
For all those who have not heard about ACTA and SOPA in short this is anti freedom of speech treaty, which if put in action could lead to serious filtering of the internet.
The ACTA 's controversial treaty has already raised an outcry from dozens of computer literated individuals who daily use the internet. Unfortunately, ACTA is less known among non-tech guys … and hence most people on the internet have no about its existence.

If ACTA is ratified and set to be valid as a legislation to Bulgaria, this could lead to total Internet censorship in BG (more or less like it is in china now).
ACTA legislation will make sharing files via torrents and other P2P community file sharing networks a criminal activity.
Another effect of ACTA is that practically free software which reads a proprietary formats like DVD becomes illegal in Europe (like it is currently in America) and I will become guilty for just reading the non-free format..
As a result of ACTA our ISP (Internet Service Providers) will be forced to log and keep all traffic flowing through their (Routering servers). Filters on a local ISP level that will be censoring free speech could also become totally lawful…
Already there are plenty of ANTI-ACTA and ANTI-SOPA propaganda website which are trying to bring some more awareness to the public for the issue… Once an individual is suspected, to fraudulent activity or anything that breaks what is in ACTA is he is presumed to be guilty of crome …
Just watch the two videos below and you will see how terrible the consequence could be if this legislation is integrated with todays Bulgarian government laws. If you're hearing for ACTA for a first time and you live in a country which has still not rafitied ACTA as a local country legislation, make sure you spread the word and let all your friends about the bad impact of this anti-human legislation. We have to really stand up and protest to retain our digital freedom !

The Internet can be censored if Protect IP ACT (PIPA) and Stop Online Piracy Act (SOPA) are put in action !

ANTI-ACTA – Hmmm But What can you do??
