Intestesting Readings
From sometime I'm invetigation into
the OpenBSD's pf here. In that manner of thoughts I found two good
reading. The first one is located here and is a sort of step
by step introduction to pf and it's capabilities+examples while the
other one is just a good security doc called "The Six Dumbest Ideas
in the Computer Security" read it
here

Interetesting Parable
Here it goes: In one of the Indian
islands, the inhabitants of a state agreed that each year they
would appoint a stranger as their ruler. When his year was over,
they would banish him, and he would return to the status he had
prior to his appointment. Once they appointed over them a fool, who
was unaware of their secret plan for him. He accumulated much
money, built palaces which he fortified, but he sent nothing out of
the country. On the contrary, whatever he had abroad - his money,
his wife and children - he brought into the country. When his year
was over, the citizens sent him out, stripped of everything and
deprived of all that he had build or acquired from the beginning of
his term until its end, so that when he left he had nothing of all
that had been his inside the city and outside of it. He regretted
and grieved for the trouble he had gone to and the effort he had
expended in building and accumulating what was then passed on to
another. Then, the people decided to appoint as their ruler a
stranger who was wise and discerning. When appointed, he chose one
man among them, showed him favor, and asked him about the customs
of the people and their laws [which had formed the basis of their
relationship] with his predecessors. This man revealed to him their
scheme, what they intended to do to him. Once he knew this, he
devoted himself to none of the pursuits that had preoccupied his
predecessor. Rather he labored and strove to take everything that
was valuable in the state to another state; all that was precious
and dear to him he put in a different place. He placed no trust in
the adulation and honor that they showed him. He fluctuated between
grief and joy the whole time that he was in the country. He grieved
that he was soon to depart, and that the precious things he had
managed to take out were few. For if he could have stayed longer,
he would have been able to bring out more. But he was glad that he
would soon leave and settle in the place where he had secured his
valuables, where he would be able to use them and enjoy their
various benefits and pleasures with people of mind, confidents
spirit, and without interruption. When his year had ended he was
not troubled at leaving, but hastened to it with heartfelt joy and
calm, applauding [himself for] his action and efforts. He went on
to abounding good, great honor, and continuing joy. So he had
happiness in both situations, and attained his wishes in both
places. The mind: You have just given, in the parable you related,
a picture of your state in this world and shown that your condition
in it is like that of the kings you mentioned. It is now clear to
you that you are a stranger [here] and will soon depart. You should
therefore act as the wise and discerning ruler did, so that your
condition may be like his. Should you deviate from this course, my
worlds will be of no use to you, my fine language will bring you no
advantage. The soul: If I had no desire in this matter, I would not
have troubled to investigate what is hidden from me of [the nature
of] my being.

Today
Today we had the ordinary "Business
Meeting" in the Business Communication classes. Also I did some
work on the snorts at work. I went to see Ivo and Zlatina (Zlatina
is a cousin) and Ivo is her husband very nice couple. I always
enjoy to stay in their furniture shop. Also I played a bit with
their Laptop Toshiba. I installed Ubuntu on it + the Edubuntu
package. Although my cousin doesn't have any experience with Linux
she managed to work with it and update it with no problems. It
looks the guys from ubuntu has done a good job. After having a
dinner I went to see my grandma (I haven't seen her yesterday and
she was missing me:). Unfortunately she has a terrible pains in her
legs, she is suffering from diabetis. I was in her home when
Damqncho (A friend of mine called and we have arranged a meeting in
20 minutes. After seeing Damqncho on the city center I saw uncle
Plamen wandering around and invited him to join us. We 3 had a walk
together and after that I went home and right now I'm posting this
thread. Well that's it end of story

No Title
Today I helped my cousing to fix his
internet connection on a laptop. The laptop was running Vista. A
real nightmare, this OS is really heavy and even messier than
Windows XP. What else I'm trying to cope with life. Life is tough.
What I can say. Also I started a vsftp server on a FreeBSD box it
took me some time because of configuration issues. Right now I'm
trying to run a snort server still unsuccessfully for some reason
the snort daemon does not start. In the college everything is going
in the old manner, except we have started studying Marketing II and
another subject I forgot the name it is supposed to be something
like statistics. The day was quiet with a bit of work.

FreeBSD 7 Installation and setup for tightened security / Multiple IPs in Jail problems
In Saturday I went to Bergon. To help
with the install and configuration of a FreeBSD 7 system to Static
and Kiril(e.g. Arkadietz). The install went smoothly. Then I
csupped following the handbook canonical way for rebuild world and
kernel and stuff. Also I get to know personally the Bergon's ISP
owner and administrator Drago btw he looks like really good man. We
spoke about the GDBOP actions when some times ago GDBOP agents
break into a server room next to the office and took Bergon's
storage servers for users http://free-zone.cc (An FTP for Users).
He said the GDBOP IT specialists doesn't know even elementary unix
commands like "df" and "du" and he had to tell them what to type.
We walked through the server's room. He had some interesting
servers I also observed the fiber optics and stuff. After setupping
the newly installed server to the server room. We went to the place
"Seasons" and we drinked "Stolichno Tymno" and we ate Pizza on
drago's account. The idea of this FreeBSD installation was to make
the machine hera.bergon.net a freeshell machine for local Bergon
users as secure as possible. To achieve that I have set this sysctl
settings: security.bsd.see_other_uids=0
security.bsd.see_other_gids=0 net.inet.tcp.msl=7500
net.inet.tcp.blackhole=2 net.inet.udp.blackhole=1
net.inet.icmp.icmplim=50 kern.ipc.somaxconn=32768 Also I have
installed AIDA
. Also I have setupped jail with the idea to add the users into
jail unfortunately. After running the jail I experienced problems
with setupping multiple ips into the jail so I asked for help in
##freebsd in freenode it turned out that by default FreeBSD jail
doesn't support virtual IPs but there is a patch to enable that
unfortunately the patch is for still for FreeBSD 5,6 or 6.2 none
available for 7. After some discussion in ##freebsd I found out
there is something that would do the work but it's not still stable
enough it's called VIMAGE, VIMAGE looks promising but will be ready
maybe in FreeBSD 8 check it out here . The only think which
left from the FreeBSD configuration is to setup firewall I intend
to make a firewall based on "PF" but I have to spend some time
reading for PF. Also I've upgraded the kernel at home to: FreeBSD

hipo@jericho.pcfreak:/usr/obj/usr/src/sys/GENERIC i386 Apart from
the geek stuff, yesterday I was to the fountain with Narf, today I
had a walk in the Central park with Damqncho. Yesterday and today
were quiet days thanks ofcourse to God almighty Also Our Heavenly
Father gives me peace through our Lord and Saviour Jesus Christ day
after day through the Power of the Holy spirit Unfortunately still
I'm not too much of a healthy. But I still say The Lord is my rock
I won't be in use! Today in the college we had a business Meeting
on the topic of "A New Product" I was the Personnel Manager, the
last time meeting I was a head of sales. After school and going out
for a walk I went to my grandma and grandpa Georgi and Dimitrichka,
after that I went to see my other grandma which is so a cool
grandma (I love her much). Another good news even though they're
old ones are that my grandmother decided to give me 150$ more for
buying the laptop. The only thing left is to choose the right
laptop :). In USA thinkpads T series are so cheap starting from
(around 950$), a good model costs something like 1150$ the same
models here cost almost 1800$ pff... To end this post I would say I
thank The Lord for giving me quiteful and peaceful days and
blessing me in my work and in my studies. Hope he will continue to
bless me in the future too.

Mysqlreport
Check this out. Mysqlreport is a
small script intended to Make easy-to-read MySQL status reports. It
has also a nice manual explaining every variable it returns. Check
it out here . From
yesterday I feel a little sich just like I guess I've catched a
flu. I'm still looking for a what kind of laptop to buy. Everybody
says a different thing. A friend of mine who sells laptop says
Gigabyte is a good choice, still I'm uncertain about that. I
personally like Thinkpads but unfortunately thinkpads comes with OS
installed on them and also I don't like it that IBM Thinkpads (e.g.
nowhere days Lenovo Thinkpads) at least the cheaper ones come with
Integrated ATI video. I'm thinking of a Dell as a possibility but
still I'm in doubt which one to take ... For all those who doesn't
know IBM/Lenovo has three major series of Thinkpads the "r" series
"t" series from Terminator :), and the "x" series. x series
thinkpads are a way smaller than "r" and "t" series. As I've heard
from friends and other sources online "t" series are rock solid and
had a titanium backing. A good thing about Thinkpads to note is
that the batter life of "r" and "z" series is 3.5 h What I can afford
is to spend no more than 1600 lv. (something like 1200 USD) for a
laptop. The Dell models I liked were Inspiron 1520 but
unfortunately they come with integrated wifi card which is dell and
has no support for Linux/BSD (I need the computer to run
FBSD/linux). Ofcourse I can always use NDIS and use the windows
driver under linux/BSD but this is not the idea

Dr. Strangelove or How I learned to stop worrying and love the bomb
Few days ago I watched Dr.
Strangelove or How I learned to stop worrying and love the bomb. An
awesome film. Although it's from 1964 it's still very fascinating.
I liked that film that much that actually I wanted to watch it
again right after I watched it. I strongly recommend it to everyone
out there. BTW as a whole Kubrick is a really genius director and
producer what I didn't like is some of his works are too perverse
and violent. An interesting fact about Kubrick is that he is a Jew.
So my guess is he is blessed just like every Jew out there.

A serious kernel vulnerability allows local attackers to attain root privileges
A new exploit is out vmsplice Local
root exploit. All Linux users are advised to update. Debian has
released a new package fixing the issue.
http://www.securityfocus.com/archive/1/487876 A friends of mine
static informed me that the exploit
Doesn't rewt an updated CentOS. My debian system has proved
vulnerable. I was pretty much surprised when a friend of mine
called and said hey man try logging with your user "hipo" :). I
suspected something is wrong maybe he have changed my username
pass. Luckily he hasn't although later I was not able to login :).
He just tested the new exploit below on pc-freak. Luckily I have
such friends to remind me of a problems very early. I guess this
exploit is going to put a lot of havoc in the Linux world. But
yeash that's life. Today Plamenko the guitarist came home and was
my guest. We have downloaded some of hi (mountain clips) and put
them on DVDs. Later I drinked a coffee with arkadietz and static.
They were in an euphoria because of this exploit. I advice
everybody there to patch as fast as possible or expect surprises

BSD tips
On one of my previous posts I give an
url to a great wiki. Unfortunately I have seen I have given a wrong
link here is the mediawiki
bsdtips.utcorp.net Today I have to go to a German classes. I'm
in doubt what kind of laptop to take I doubt between IBM Thinkpad
and Dell. IBM's has ati where I prefer having nvidia. On the other
hand I know not all of Dell's hardware would probably work
correctly in Linux and BSD. Another problem is IBM is being selled
with preinstalled XP ...

Cisco Courses or how the Sunday passed?
In the morning I stand up somewhere
around 8:40 I went to a Liturgy as always. It's such a joy to be in
the House of the LORD! Right after the Church going I, nomen and Sha'nar (e.g.
Niki) had to go to a Cisco Course. It was a sort of boring as
usual. After the course we went to a Coffee called central (I and
Niki ate spaghetti with vegetables). Just after that I saw Lily.
I'm really sad that her parents treat her bad just like mine treat
me sometimes. But I believe and hopeGod would solve everything very
soon. After that in home I have to make the Cisco Assessment Tests
for Chapter 6 6/7 in CCNA 1. On some of the questions I cheated
because I was pretty lazy to search in the Cisco docs about to
figure out the answers by myself here is the site where answers to
CCNA 1 are available CCNA Answers . Towards the
evening Damqncho called and I went to see him and later, three of
us went to a coffee. I have to note that my "inancial status" is
not in too good conditions Nomen tipped all the time for which I'm
largely thankful :). Also I have to share my joy from yesterday
because my grand parents (My father ones) decided to make me a
present and give me a sum of 1000 lv. to buy a laptop. Actually
having a laptop is a dream of mine for years. Also what I have to
note is this is a direct response to a prayer. Few times ago I
mentioned in my prayers that I need a laptop what can I say. I
guess God heard my prayers. So Glory be to him for being so
merciful to me and the whole earth! Be blessed oh God Lord of Hosts
!
Yesterday was a pretty funny day too I met Hellpain a friend of
mine who works in Sofia but temporary he is on a official trip in
Varna. So I spend almost 3 great hours with this great guy!
At Friday
Night I and Alex drinked wine in the central park (again good spned
time). What should be noted is that friday is a celebrity called
"Trifon Zarezan" or said in a simple english The Alcohol lover's
day :). It's a tradition for a long time on this day for a close
friends to gather together and drink heavily. I haven't had so much
fun for a lot of time. So thanks and Glory to God who grant me with
all this I
can see a great blessing with a good guys friends in my life. So
anywayz I have to say again Thanks to God for all his mercies to me
the sinner

The end of the work week :)
One more week passed without serious
server problems. Yesterday after upgrade to debian 4.0rc2 with
apt-get dist-upgrade and reboot the pc-freak box became unbootable.
I wasn't able to fix it until today because the machine's box
seemed not to read cds well. The problem was consisted of this that
after the boot process of the linux kernel has started the machine
the boot up was interrupted with a message saying /sbin/init is
missing and I was dropped to a busybox without being able to read
nothing from my filesystem. Thankfully nomen came to Dobrich for
the weekend and today he bring me his cdrom I booted with the
debian. Using Debian's linux rescue I mounted the partition to
check what's wrong. I suspected something is terribly wrong with
the lilo's conf. Looking closely to it I saw it's the lilo conf
file it was setupped to load a initrd for the older kernel.
changing the line to the new initrd in /etc/lilo.conf and rereading
the lilo; /sbin/lilo -C; /sbin/lilo; fixed the mess and pc-freak
booted succesfully! Yesterday I had to do something kinky. It was requested
from a client to have access to a mysql service of one of the
company servers, the problem was that the client didn't have static
IP so I didn't have a good way to put into the current firewall.
Everytime the adsl they use got restarted a new absolutely random
IP from all the BTC IP ranges was assigned. The solution was to
make a port redirect to a non-standard mysql port (XXXXX) which
pointed to the standard 3306 service. I had to tell the firewall
not to check the coming IPs on the non-standard port (XXXXX)
against the 3306 service fwall rules. Thanks to the help of a guy
in irc.freenode.net #iptables jengelh I figured out the solution.
To complete the requested task it was needed to mark all packages
coming into port (XXXXX) using the iptables mangle option and to
add a rule to ACCEPT all marked packages. The rules looked like
this /sbin/iptables -t mangle -A PREROUTING -p tcp --dport XXXXX -j
MARK --set-mark 123456 /sbin/iptables -t nat -A PREROUTING -d
EXTERNAL_IP -i eth0 -p tcp --dport XXXXX -j DNAT --to-destination
EXTERNAL_IP:3306 /sbin/iptables -t filter -A INPUT -p tcp --dport
3306 -m mark --mark 123456 -j ACCEPT . Something I wondered a bit
was should /proc/sys/net/ipv4/ip_forward in order for the above
redirect to be working, in case you're wondering too well it
doesn't
The working week was a sort of quiteful no serious problems with
servers and work no serious problems at school (although I see me
and my collegues become more and more unserious) at studying. My
grand parents decided to make me a gift and give me money to buy a
laptop and I'm pretty happy for this All that is left is
to choose a good machine with hardware supported both by FreeBSD
and Linux.
