Windows: command to show CPU info, PC Motherboard serial number and BIOS details

Wednesday, March 2nd, 2016

windows-command-to-show-motherboard-bios-and-cpu-serials-and-specific-info-with-wmic

Getting CPU information, RAM info and other various hardware specifics on Windows from the GUI interface is pretty trivial from Computer -> Properties
even more specifics could be obtained using third party Windows software such as CPU-Z

Perhaps there are plenty of many other ones to get and log info about hardware on PC or notebook system, but for Windwos sysadmins especially ones who are too much in love with command prompt way of behaving and ones who needs to automatizate server deployment processes with BATCH (.BAT)  scripts getting quickly info about hardware on freshly installed remote host Win server with no any additional hardware info tools, you'll be happy to know there are command line tools you can use to get extra hardware information on Windows PC / server:

The most popular tool available to present you with some basic hardware info is of course systeminfo

…..


Now though systeminfo's hardware details and installed Windows KBXXXXX OS Hotfix patches are getting lists the command does not provide you with info about  system’s BIOS, thus to get this info you'll have to use also wmic (Windows Management Instrumentation Command).
 

 

So What Is WMIC?

WMIC extends WMI for operation from several command-line interfaces and through batch scripts. Before WMIC, you used WMI-based applications (such as SMS), the WMI Scripting API, or tools such as CIM Studio to manage WMI-enabled computers. Without a firm grasp on a programming language such as C++ or a scripting language such as VBScript and a basic understanding of the WMI namespace, do-it-yourself systems management with WMI was difficult. WMIC changes this situation by giving you a powerful, user-friendly interface to the WMI namespace.

WMIC is more intuitive than WMI, in large part because of aliases. Aliases take simple commands that you enter at the command line, then act upon the WMI namespace in a predefined way, such as constructing a complex WMI Query Language (WQL) command from a simple WMIC alias Get command. Thus, aliases act as friendly syntax intermediaries between you and the namespace. For example, when you run a simple WMIC command such as

Here is how to wmic to get PC Motherboard serial numbers, CPU and BIOS details:

 

C:\> wmic bios get name,serialnumber,version

 

Above will print  name if your BIOS, current version and it’s serial number if there is any.

If you need to get more info about the specific Motherboard installed on host:

 

C:\> wmic csproduct get name,identifyingnumber,uuid

 

This command will show motherboard modification and it’s UUID

If you want to quickly get what is Windows running hardware CPU clock speed
 

C:\> wmic cpu get name,CurrentClockSpeed,MaxClockSpeed

 

Also if you have turbo boost CPUs above command will help you find what’s the Max Clock Speed your system is capable of for the current hardware configuration.

If you do have dynamic clock speed running, then add this line, will refresh and monitor the Clock speed every 1 second.
 

C:\> wmic cpu get name,CurrentClockSpeed,MaxClockSpeed /every:1

Actually wmic is a great tool

Fix “FAIL – Application at context path /application-name could not be started” deployment error in Tomcat manager

Thursday, October 1st, 2015

tomcat-manager-FAIL-Application-at-context-path-application-name-could-not-be-started-fix-solution-error

While deploying an environment called "Interim" which is pretty much like a testing Java application deployed from a Java EAR (Enterprise Archive) file from within a Tomcat Manager GUI web interface after stopping the application and trying to start it, the developers come across the error:

 

FAIL – Application at context path /application-name could not be started


The error puzzled me for a while until I checked the catalina.out I've seen a number of thrown Java Eceptions errors like:

Okt 01, 2015 10:48:46 AM org.springframework.web.context.ContextLoader initWebApplicationContext

Schwerwiegend: Context initialization failed

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'com.sun.xml.ws.transport.http.servlet.SpringBinding#2' defined in ServletContex

t resource [/WEB-INF/pp-server-beans.xml]: Cannot create inner bean ‘(inner bean)’ of type [org.jvnet.jax_ws_commons.spring.SpringService] while setting bean property

'service'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name '(inner bean)#33': FactoryBean threw exception on

 object creation; nested exception is java.lang.OutOfMemoryError: PermGen space

I've googled a bit about the error:

"FAIL – Application at context path /application-name could not be started"

and come across this Stackoverflow thread and followed suggested solution to fix web.xml tag closing error but it seems there was no such error in my case, I then also tried solution suggested by this thread (e.g. adding in logging.properties) file:
 

org.apache.catalina.core.ContainerBase.[Catalina].level = INFO
org.apache.catalina.core.ContainerBase.[Catalina].handlers = java.util.logging.ConsoleHandler

unfortunately this helped neither to solve the error when it is tried to be started from tomcat manager.

After asking for help a colleague Kostadin, he pointed me to take a closer look in the error (which is a clear indication) that the reserved space is not enough (see below err):
 

java.lang.OutOfMemoryError: PermGen space

And he pointed me then to Solution (which is to modify the present tomcat setenv.sh) settings which looked like this:

# Heap size settings

export JAVA_OPTS="-Xms2048M -Xmx2048M"

 

# SSCO test page parameter

export JAVA_OPTS="$JAVA_OPTS -DTS1A_TESTSEITE_CONFIG_PATH=test-myapplication.com"

# Default garbage collector settings

export JAVA_OPTS="$JAVA_OPTS -XX:MaxPermSize=128M"

 

# Aggressive garbage collector settings.

# Do not use! For testing purposes only!

#export JAVA_OPTS="$JAVA_OPTS -Xss128k -XX:ParallelGCThreads=20 -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -XX:SurvivorRatio=8 -XX:TargetSurvivorRatio=90 -XX:MaxTenuringThreshold=31 -XX:+AggressiveOpts -XX:MaxPermSize=128M"

 

####### DO NOT CHANGE BELOW HERE #######

# Disable X11 usage

unset DISPLAY

export JAVA_OPTS="$JAVA_OPTS -Djava.awt.headless=true"

 

# Garbage collection log settings

export JAVA_OPTS="$JAVA_OPTS -verbose:gc -XX:+PrintGCTimeStamps -XX:+PrintGCDetails -Xloggc:/web/tomcat/current/logs/gc.log -XX:-TraceClassUnloading"

 

# Enable JMX console

export JAVA_OPTS="$JAVA_OPTS -Dcom.sun.management.jmxremote"

 

 

 

 

 

 

The solution is to to add following two options to export JAVA_OPTS (above options):

-XX:PermSize=512m -XX:MaxPermSize=512m


After modifications, my new line within setenv.sh looked like so:

 

JAVA_OPTS="-Xms2048M -Xmx2048M -XX:PermSize=512m -XX:MaxPermSize=512m"


Finally to make new JAVA_OPTS settings, I've restarted Tomcat with:

 

cd /web/tomcat/bin/
./shutdown.sh
sleep 5; ./startup.sh


And hooray it works fine thanks God! 🙂

PortQRY Native Windows command line Nmap like port scanner – Check status of remote host ports on Windows

Monday, June 30th, 2014

Windows_command_line_and_gui_port-scanner-portqry-like-nmap-check-status-of-remote-host-service-windows-xp-7-2000-2003-2008-server
Linux users know pretty well Nmap (network mapper) tool which is precious in making a quick server host security evaluation.
Nmap binary port is available for Windows too, however as nmap is port for its normal operation you have to install WinPcap (Packet Capture Library).
And more importantly it is good to mention if you need to do some remote port scanning from Windows host, there is Microsoft produced native tool called PortQry (Port Query).

PortQRY is a must have tool for the Windows Admin as it can help you troubleshoot multiple network issues.

windows-nmap-native-alternative-portqry-gui-ui-web-service-port-scan-screenshot
As of time of writting this post PortQRY is at version 2, PortQRY tool has also a GUI (UI) Version for those lazy to type in command line.

Port Query UI tool (portqueryui.exe) is a tool to query open ports on a machine. This tool makes use of command line version port query tool (portqry.exe). The UI provides the following functionalities:

   1. Following "Enter destination IP or FQDN to query:”, an edit box needs the user to specify the IP address or FDQN name of the destination to query port status.

   2. The end user is able to choose Query type:

        – Predefined services type. It groups ports into service, so that you can query multiple ports for a service by a single click. Service includes "Domains and Trusts", "DNS Queries", "NetBIOS     communication", "IPSEC", "Networking", "SQL Service", "WEB Service", "Exchange Server",          "Netmeeting", and other services.

You can check detail port and protocol info for each service category by opening Help -> Predefined Services…

PORTQRY is part of Windows Server 2003 Support Tools and can be added to any NT based Windows (XP, 2003, Vista, 7, 8)
 You can download portqry command line tool here or my mirrored portqry version command line port scanner here and PortQRY UI here.

PortQRY comes in PortQryV2.exe package which when run extracts 3 files: PortQry.exe program, EULA and readme file. Quickest way to make portqry globally accessible from win command prompt is to copy it to %SystemRoot% (The environment variable holding default location for Windows Installation directory).
It is good idea to add PortQRY to default PATH folder to make it accessible from command line globally.

PorQry has 3 modes of operation:

Command Line Mode, Interactive Mode and Local Mode

portqry-windows-native-security-port-network-scanner-nmap-equivalent-help-screenshot
 

Command Line Mode – is when it is invoked with parameters.

Interactive Mode is when it runs in interactive CLI console

portqry-windows-native-security-port-network-scanner-nmap-equivalent-interactive-mode-screenshot

portqry-windows-native-security-port-network-scanner-nmap-equivalent-interactive-mode-help-screenshot
and Local Mode is used whether information on local system ports is required.

portqry-windows-native-security-port-network-scanner-nmap-equivalent-local-mode-screenshot


Here are some examples on basic usage of portqry:
 

1. Check if remote server is running webserver is listening on (HTTPS protocol) TCP port 80

portqry -n servername -e 80
 

Querying target system called:

 pc-freak.net

Attempting to resolve name to IP address…


Name resolved to 83.228.93.76

querying…

TCP port 80 (http service): FILTERED

2. Check whether some common Samba sharing and DNS UDP ports are listening

portqry -n servername -p UDP -o 37,53,88,135
 

Querying target system called:

servername

Attempting to resolve name to IP address…


Name resolved to 74.125.21.100

querying…

UDP port 37 (time service): NOT LISTENING

UDP port 53 (domain service): NOT LISTENING

UDP port 88 (kerberos service): NOT LISTENING

UDP port 135 (epmap service): NOT LISTENING

3. Scan open ports in a port range – Check common services port range (port 1-1024)

portqry -n 192.168.1.20 -r 1:1024 | find ": LISTENING"

4. Logging network scan output to file

Portqry –n localhost –e 135 -l port135.txt
 

Querying target system called:

 localhost

Attempting to resolve name to IP address…


Name resolved to 127.0.0.1

querying…

TCP port 135 (epmap service): LISTENING

Using ephemeral source port
Querying Endpoint Mapper Database…
Server's response:

UUID: d95afe70-a6d5-4259-822e-2c84da1ddb0d
ncacn_ip_tcp:localhost[49152]

UUID: 2f5f6521-cb55-1059-b446-00df0bce31db Unimodem LRPC Endpoint
ncacn_np:localhost[PIPEwkssvc]

Total endpoints found: 38


5. Scanning UDP and TCP protocols port

PortQry -n www.pc-freak.net -e 25 -p both

 

Querying target system called:

 www.pc-freak.net

Attempting to resolve name to IP address…


Name resolved to 83.228.93.76

querying…

TCP port 53 (domain service): LISTENING

UDP port 53 (domain service): LISTENING or FILTERED

Sending DNS query to UDP port 53…

 

6. Checking remote server whether LDAP ports are listening

Portqry -remotehost.com -p tcp -e 389
Portqry -n remotehost.com -p tcp -e 636
Portqry -n remotehost.com -p both -e 3268
Portqry -n remotehost.com -p tcp -e 3269


7. Making SNMP community name requests

portqry -n host2 -cn !my community name! -e 161 -p udp


8. Initiating scan from pre-selected source port

A network socket request initiation is useful from certain port because, some remote services expect connection from certain ports, lets say you're connecting to mail server, you might want to set as a source port – port 25, to make remote server another SMTP is connecting.

portqry -n www.pc-freak.net -e 25 -sp 25


9. Scanning whether server ports required by Active Directories are opened

Common ports used in Windows hosts to communicate between each other to sustain Active Directory are:

88 (Kerberos)
135 (RPC)
389 (LDAP)
445 (CIFS)
3268 (Global Catalog)

portqry -n remote-host.com -o 88,135,389,445,3268 -p both

portqry has also a silent mode with the "-q" switch if you want to get only whether a port is LISTENING (opened).

On port scan it returns three major return codes (very useful for scripting purposes);

  • returncode 0 – if port / service is listening
  • returncode 1 – if service is not listening
  • returncode 2 – if service is listening or filtered

PortQry is very simple port scanner for win sysadms and is precious tool for basic network debugging (services)  on Windows farms, however it doesn't have the powerful cracker functionality, application / OS versioning etc. like Nmap.

Thomas Sunday – The day of Disbelievers

Monday, April 28th, 2014

Thomas-sunday-the-day-of-disbelieve-Thomas-reaching-to-Jesus-wounds

A week passed since we Christian celebrated Resurrection of Christ (Pascha). Each year on first Sunday after Easter in orthodox Church is celebrated the so called Thomas Sunday. So why is it called Thomas Sunday and why it is the day of disbelievers?
The root of this ancient Christian feast comes after commemoration of Christ desciple St. Thomas who disbelieved the testimony of ( 10 apostles ) and the Virgin Mary  that Jesus Christ is Risen from the Death.

The disbelieve of Thomas was logical and human cause even though Thomas was with the Apostles with Christ for 3 years, saw all Jesus miracles and shared the Secret Supper (Last Supper), and even knew in advance (heard by Jesus on Last supper) that Jesus will betrayed mocked, hanged on the Cross and Rise from the death on the third day, he disbelieved.

Thomas Sunday (Sundy of Thomas) is "the day of Disbelievers", because all are disbelievers in moments of their life not only those who believe God but all the humanity!  Even the most faithful Christian, be it a deacon, monk or priest has difficult moments in life where God's existence or providence for one's faith is seriously questioned.
The fallen nature of man is such that the initial belief in God given to man in Eden (Paradise garden) is broken, and only in Jesus's name through the Gift of Faith given by the Holy Spirit, believe in God is restored.

Thomas very much like unto everyone of us doubted the rumors of Christ resurrection and said he would only believe in Resurrected Christ only if he sees his hands nails print and put his fingers into Christ’s wounds to test he is not seeing a Ghost but Christ is alive in a body after his death.

Here is the Gospel reading re-telling the story in short:

“Then the same day at evening, being the first day of the week, when the doors were shut where the disciples were assembled for fear of the Jews, came Jesus and stood in the midst, and saith unto them, Peace be unto you.” (John 20:19)

“But Thomas, one of the twelve, called Didymus, was not with them when Jesus came. The other disciples therefore said unto him, We have seen the Lord. But he said unto them, Except I shall see in his hands the print of the nails, and put my finger into the print of the nails, and thrust my hand into his side, I will not believe.” (John 20:24-26)

And after eight days again his disciples were within, and Thomas with them: then came Jesus, the doors being shut, and stood in the midst, and said, Peace be unto you.
Then he said to Thomas, “Put your finger here; see my hands. Reach out your hand and put it into my side. Stop doubting and believe.”
Thomas said to him, “My Lord and my God!”
Then Jesus told him, “Because you have seen me, you have believed; blessed are those who have not seen and yet have believed.”
Jesus did many other miraculous signs in the presence of his disciples, which are not recorded in this book.
But these are written that you may believe that Jesus is the Christ, the Son of God, and that by believing you may have life in his name.” (John 20:31)

We Christians should be joyful for have not seen Christ in Flesh but have believed for we are blessed for his believe without seeing.

By same faith in God without seeing him even in old times the Jews were led by the Lord God in the desert have won wars by their believing without seeing God, prophets has prophecised, Simeon (The God receiver) hold The Savior (Christ) in his hands, by faith David won the battle with Goliath, by faith we understand the universe was formed at God’s command, by faith we know that the visible came out of the invisible.

o Kyrios mou kai o Theos mou (Greek) – My Lord and my God (Jn. 20:28) this declaration of faith clearly shows an unexpressable excitement of Thomas and his unexpectency to see Christ resurrected. Here it is interesting that here the son of God Jesus Christ is called by Thomas exactly how Jewish used to call God Yahweh (One and Only God) in the Old testament.

Today the evangical story is very accurate for our generation – a generation of disbelievers, even we who say we believe often doesn’t justify our believe with our deeds, we say we believe but we don’t keep God’s commandment “to love God and our neigbor like ourselves.” Often only difference between believers and disbelievers is on Sunday we believers visit Church and “play Christians”, but even but in daily life our deeds are same like unbelievers. Often many are disbelievers not because they reject God but because they never heard the Gospel or misheard it, also we disbelieve because we’re very much like st. Thomas, we often say “I will believe in God if I see him”, but even Thomas who saw God before the Crucifix and knew him disbelieved – a proof that often seing once could still leave space for doubt. The glorious event of Christ showing himself Alive to Thomas was made by Christ to establish the Church and strengthen faith of first Christians in resurrection. Nowadays there are plenty of people who question God’s existence saying that they will believe if they see but they’re not given to see the resurrected Christ because God knows that even if we see the Lord Jesus Christ resurrected we would try to rationally explain the phenomenon with holograms, modern technology or science.

Thomas Sunday is not only a day of Thomas disbelieve it is a day of disbelieve of all humanity. , St. Thomas should be an example even to all of us Christian disbelievers and non-believers that even if we disbelieve and doubt and strive to see God, He is powerful to come and appear Resurrected in His Glory to our souls.
Let us therefore have the Wisdom of the Holy Apostles and say together with them “Lord, Increase our faith.” Luke 17:5

Sofia Bulgaria one of the Most Ancient cities in Central Europe – the History of Europe

Friday, January 18th, 2013

Many Bulgarians might be striken to find out, today's territory of Bulgaria and on the balkans is in practice one of the ancient inhabitant territories in Europe. Sofia or Serdika, Sredets as the old name of Sofia used to be part of Roman Empire (Byzantine Empire), then of pre-Christian Bulgaria, after Christianization of Bulgaria part of the Bulgarian Empire and then after the fall of Bulgaria under turkish yoke part of Ottoman's Turkish Empire. Maybe surprisingly for many Western Europeans the city of Sofia, happened to be one of the ancient cities important for Christianity as it had a Bishop standing and a strong Christian community since 3rd century A.D. Even until today Sofia has kept its city design which is made in a Roman fashion. Hope this little video unusually made by British will shed up some light to people interested in Ancient Christian history. Enjoy 🙂

History of Belarus in 5 minutes – Learn a lot for Belarus in short time

Tuesday, October 30th, 2012

I've been recently interested in Belarusian History. I found few very interesting videos in youtube, so decided with people who want to learn more about Slavonic Culture. Belarus is a Slavonic culture and old Belarusian language dates back to Ancient Bulgarian traditions. Also Belarusian Ancient language includes a lot of Slavonic Ancient Bulgarian words. As a Bulgarian it is very interesting to me too the severe impact that our Great Bulgarian nation had on Slavonic Nations and Russians. Belarusians both lingually and culturely are very close to us Bulgarian. Orthodox Christian faith which later spread in Belarusian lands, has also been transferred from Bulgarian and Serbian lands to Belarus. After the pupils of Saint Cyril and Methodius, spread Slavonic alphabet in nowdays Romanian lands, Moldova and Belarus.
The first below video Belarus History in 5 minutes has a genuine video and musical arrangment. It was quite interesting to me, find out Belarussian people had a long known tradition in Musical Instruments and Folklore Music. Nowdays they produce also a great Gothic Music, just like most of celtic nations 🙂

History of Bulgarus in 5 minutes – Aristic short presentation lesson on Belarussian history


0:02
At first, there was nothing

 

0:03
now there’s a lot of everything

 

0:04
we have to thank God for that

 

0:06
He created our world in the freestyle genre

 

0:09
He said, "Budzma" (“So be it!”)

 

0:10
and Our Land appeared.

 

0:11
Ichthyosauri and other dragons…

 

0:13
in the beginning, we lived in the ocean

 

0:15
but then we left the bosom of the sea

 

0:17
and started to be called the Neuri.

 

0:19
From the earliest times

 

0:21
the Neuri could turn into wolves

 

0:23
that was a customary thing for them…

 

0:26
Žycien, Piarun, Dažboh, and Svaroh

 

0:28
our ancestors believed in heathen gods

 

0:30
but Christianity already knocked on the door.

 

0:34
Let’s know our roots! The Belarusians, the daring people!

 

0:38
In the year 862 of our era

 

0:41
the city of Polacak was mentioned for the first time

 

0:43
There, St. Safija Cathedral was build

 

0:45
(there’re only three such churches in the world)

 

0:47
Local Prince Usiaslau Caradziej

 

0:49
was a cool personage; Listen what I say!

 

0:51
St. Jefrasinnia lived in Polacak

 

0:53
the memory of her is cherished down the ages

 

0:56
The famous cross was made for her

 

0:58
(it wasn’t just super, it was marvelous)

 

1:00
but during WWII, it was lost

 

1:02
and now it’s our own grail

 

1:04
Let’s continue, let’s march ahead

 

1:07
The time of Grand Prince Mindouh came

 

1:09
and here we must remember that

 

1:11
Belarus was called Litva then

 

1:13
or rather – the Grand Principality of Litva

 

1:15
its coat of arms was Pahonia (pursuit)

 

1:16
it had a formidable army

 

1:17
Our capital Vilnia was founded by

 

1:19
Grand Prince Hiedymin

 

1:21
the legend says he had a dream about an iron wolf…

 

1:24
Wikipedia describes this event

 

1:26
Let’s know our roots!

 

1:28
The Belarusians, the daring people!

 

1:31
The year 1362

 

1:34
The sword is drawn; flags flutter in the wind…

 

1:36
In the Battle of Blue Waters

 

1:38
our army defeated three Khans of the Golden Horde

 

1:41
and the Grand Principality of Litva suddenly

 

1:43
became the largest country in Europe

 

1:45
Let’s continue, let’s march ahead.

 

1:47
Vitaut reigns in the Grand Principality

 

1:49
The Teutonic Order threatens us.

 

1:51
The Battle of Grunwald shows who’s right

 

1:53
Vitaut and Jahajla, King of Poland

 

1:55
junked the Crusaders like scrap metal

 

2:00
Francysk Skaryna was a tough guy

 

2:02
he went to study abroad

 

2:04
He was the first who printed the Bible

 

2:06
in the Old Belarusian language in Prague

 

2:08
Our warriors were tough men, too

 

2:11
they defeated the Moscow Army near Vorsa

 

2:13
in the year 1514

 

2:17
In the meantime, the Grand Principality of Litva

 

2:19
accepted its constitution – the Statute of the GPL 1588

 

2:21
In the Battle of Kircholm, we defeated the Swedish army

 

2:24
Apparently, you didn’t know this fact before.

 

2:26
Let’s know our roots!

 

2:28
In the city of Mahilou

 

2:30
7,000 invaders were killed in the fight

 

2:32
Who were these invaders? Well, these … from the East

 

2:34
representatives of the "brotherly" Russian nation

 

2:37
They were called Muscovites then.

 

2:38
And there’s already a new state

 

2:40
the Polish–Litvian Commonwealth

 

2:43
For some reason, it irritated all the neighbors

 

2:45
The three partitions of this Commonwealth

 

2:47
and we were divided between three states

 

2:49
The biggest part was occupied by Russia

 

2:51
It engendered discontent among the nobility

 

2:53
and Tadevus Kasciuska appears on the scene

 

2:56
It’s necessary to remember this name because

 

2:58
he was a great revolutionary

 

3:00
for liberty, equality and fraternity

 

3:02
he struggled even in the United States

 

3:04
but the Russian Tsar cast him into prison

 

3:06
Let’s know our roots!

 

3:10
During Napoleon’s war

Ancient Musical Instruments of Belarus

Most importantly, nowdays Belarus still hold the light of Orthodox Christian faith, just like us Bulgarians. Spiritually Bulgaria and Belarus is united in our Orthodox Christian faith. This summer, I had the blessing many Belarusians in Pomorie Monastery (An Orthodox monastery located in the Black Sea sea coast (near Burgas) in Bulgaria). I've been amazed by the faith and spirituality Belarusians still hold even in this "dark times" of Christian faith decay and increased ungodliness.

Orthodox Jewish Rabbi Reveals Name of Messiah to be “Yehoshua”, “Yeshua” (in Hebrew) – JESUS

Wednesday, July 25th, 2012

It was always interesting to me to hear for Jewish, who turned to become Christian. Hence it was quite curious to find that one of the Jewish most famous Rabbis is claimed to have tought that Yehshua (Jesus Christ) is the name of the Messiah (The Jewish are still waiting to come even to this day). Onwards in youtube, I've seen the interesting testimony of nowdays orthodox monk Father Nathanael, who was raised as a Jewish was attending regularly Jewish synagogues and has miraculously turned to Orthodox Christian faith (The Orthodox Church of America).

How to check MASTER / SLAVE MySQL nodes status – Check MySQL Replication Status

Thursday, April 19th, 2012

I'm doing replication for one server. Its not the first time I do configure replication between two MySQL database nodes, however since I haven't done it for a few years, my "know how" has mostly vanished so I had some troubles in setting it up. Once I followed some steps to configure replication I had to check if the two MASTER / Slave MySQL db nodes communicate properly. Hence I decided to drop a short post on that just in case if someone has to do the same or if I myself forget how I did it so I can check later on:

1. Check if MASTER MySQL server node is configured properly

The standard way to check a MySQL master node status info is with:
 

mysql> show master status;
+——————+———-+———————————————————+——————+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB |
+——————+———-+———————————————————+——————+
| mysql-bin.000007 | 106 | database1,database2,database3 | |
+——————+———-+———————————————————+——————+
1 row in set (0.00 sec)

By putting \G some extra status info is provided:
 

mysql> show master status\G;
*************************** 1. row ***************************
File: mysql-bin.000007
Position: 106
Binlog_Do_DB: database1,database2,database3
Binlog_Ignore_DB:
1 row in set (0.00 sec)

ERROR:
No query specified

2. Check if Slave MySQL node is configured properly

To check status of the slave the cmd is:
 

mysql> show slave status;

The command returns an output like:
 

mysql> show slave status;+———————————-+————-+————-+————-+—————+——————+———————+————————-+—————+———————–+——————+——————-+——————————————————-+———————+——————–+————————+————————-+—————————–+————+————+————–+———————+—————–+—————–+—————-+—————+——————–+——————–+——————–+—————–+——————-+—————-+———————–+——————————-+—————+—————+—————-+—————-+| Slave_IO_State | Master_Host | Master_User | Master_Port | Connect_Retry | Master_Log_File | Read_Master_Log_Pos | Relay_Log_File | Relay_Log_Pos | Relay_Master_Log_File | Slave_IO_Running | Slave_SQL_Running | Replicate_Do_DB | Replicate_Ignore_DB | Replicate_Do_Table | Replicate_Ignore_Table | Replicate_Wild_Do_Table | Replicate_Wild_Ignore_Table | Last_Errno | Last_Error | Skip_Counter | Exec_Master_Log_Pos | Relay_Log_Space | Until_Condition | Until_Log_File | Until_Log_Pos | Master_SSL_Allowed | Master_SSL_CA_File | Master_SSL_CA_Path | Master_SSL_Cert | Master_SSL_Cipher | Master_SSL_Key | Seconds_Behind_Master | Master_SSL_Verify_Server_Cert | Last_IO_Errno | Last_IO_Error | Last_SQL_Errno | Last_SQL_Error |+———————————-+————-+————-+————-+—————+——————+———————+————————-+—————+———————–+——————+——————-+——————————————————-+———————+——————–+————————+————————-+—————————–+————+————+————–+———————+—————–+—————–+—————-+—————+——————–+——————–+——————–+—————–+——————-+—————-+———————–+——————————-+—————+—————+—————-+—————-+| Waiting for master to send event | HOST_NAME.COM | slave_user | 3306 | 10 | mysql-bin.000007 | 106 | mysqld-relay-bin.000002 | 251 | mysql-bin.000007 | Yes | Yes | database1,database2,database3 | | | | | | 0 | | 0 | 106 | 407 | None | | 0 | No | | | | | | 0 | No | 0 | | 0 | |+———————————-+————-+————-+————-+—————+——————+———————+————————-+—————+———————–+——————+——————-+——————————————————-+———————+——————–+————————+————————-+—————————–+————+————+————–+———————+—————–+—————–+—————-+—————+——————–+——————–+——————–+—————–+——————-+—————-+———————–+——————————-+—————+—————+—————-+—————-+

As you can see the output is not too readable, as there are too many columns and data to be displayed and this doesn't fit neither a text console nor a graphical terminal emulator.

To get more readable (more verbose) status for the SQL SLAVE, its better to use command:
 

mysql> show slave status\G;

Here is a sample returned output:
 

mysql> show slave status\G;*************************** 1. row *************************** Slave_IO_State: Waiting for master to send event Master_Host: HOST_NAME.COM Master_User: slave_user Master_Port: 3306 Connect_Retry: 10 Master_Log_File: mysql-bin.000007 Read_Master_Log_Pos: 106 Relay_Log_File: mysqld-relay-bin.000002 Relay_Log_Pos: 251 Relay_Master_Log_File: mysql-bin.000007 Slave_IO_Running: Yes Slave_SQL_Running: Yes Replicate_Do_DB: database1,database2,database3 Replicate_Ignore_DB: Replicate_Do_Table: Replicate_Ignore_Table: Replicate_Wild_Do_Table: Replicate_Wild_Ignore_Table: Last_Errno: 0 Last_Error: Skip_Counter: 0 Exec_Master_Log_Pos: 106 Relay_Log_Space: 407 Until_Condition: None Until_Log_File: Until_Log_Pos: 0 Master_SSL_Allowed: No Master_SSL_CA_File: Master_SSL_CA_Path: Master_SSL_Cert: Master_SSL_Cipher: Master_SSL_Key: Seconds_Behind_Master: 0Master_SSL_Verify_Server_Cert: No Last_IO_Errno: 0 Last_IO_Error: Last_SQL_Errno: 0 Last_SQL_Error: 1 row in set (0.00 sec)ERROR: No query specified

If show master status or shwo slave status commands didn't reveal replication issue, one needs to stare at the mysql log for more info.

How to prevent SSH and FTP bruteforce attacks with iptables on Linux

Friday, December 30th, 2011

Earlier I've blogged about how to prevent brute force attacks with fail2ban, denohosts and blockhosts , however there is easier way to secure against basic brute force attacks by not installing or configuring any external programs.
The way I'm talking about uses simple iptables rules to filter out brute force attacks.

Here is a small script to stop ssh and FTP invaders which try to initiate more than 3 consequential connections in 5 minutes time to port 22 or port 23:

SERVER_MAIN_IP='AAA.BBB.CCC.DDD';/sbin/iptables -N SSH_WHITELIST
/sbin/iptables -A INPUT -p tcp --dport 22 --syn -m recent --name sshbr --set
/sbin/iptables -A INPUT -p tcp --dport 22 --syn -j SSH_WHITELIST
/sbin/iptables -A INPUT -p tcp --dport 22 --syn -m recent --name sshbr \
--update --rttl --hitcount 3 --seconds 300 -j REJECT --reject-with tcp-reset
/sbin/iptables -A SSH_WHITELIST -s $SERVER_MAIN_IP -p tcp --dport 22 --syn -m recent --rttl --remove

The only thinIf the rules are matched iptables filter rules will be added to the iptables CHAIN SSH_WHITELIST
In case if you want to add some more truested IPs add some more iptables rules, like:

ALLOW_IP='BBB.CCC.DDD.EEE';
/sbin/iptables -A SSH_WHITELIST -s $ALLOW_IP -p tcp --dport 22 --syn -m recent --rttl --remove

Each filtered IP that matches the rules will be filtered for 5 minutes, if 5 minutes is enough, the 300 value has to be increased.
