Recently I read a lot not typical of me things, It's pleasant ones…. (It's from before over 1 Year)

Dying slowly this…
Who does not travel,
Who does not read
And does not listen to music,
That does not detect
Fascination in yourself.

Dying slowly this…
That destroys
Your own White,
Refusing the aid,
Who is not looking for diversity.

Dying slowly this…
which turns
In Slave of Habit,
Passing every day
On the same paths,
Who does not risk
To dress in a different color
And does not talk to strangers.

Dying slowly this…
Who flees from passion
And the whirlpool of feelings,
That return the glow to the eyes
And rescue the sad hearts.

Dying slowly this…
Who doesn't change her life,
When dissatisfied with the work
Or your Love,
Who does not risk the security
About the Unknown,
To pursue a dream,
Which is not decided at least once in a lifetime
Escape the Wise Tips.

Don't die Slowly… Live today!

Risk today! ACT today!

Don't let yourself die slowly!

Don't forget to be happy!

Last weekend, she rolled TuxCon 2017. According to most people, I did a decent job with my lecture.. I personally am not quite satisfied, There are definitely a lot of things to work on, Because I plan to not be my last similar appearance in the future. To be honest on most of the presentation I hardly remember it, Was like in a trance. I remember sparse moments in which I look at the clock and establish, That a decent amount of time has elapsed.

It was definitely not easy, Even considering the, That the audience was extremely narrowly focused and there was no big barrier with the audience.


DN42 is a wonderful project that gives you the opportunity to develop your BGP skills without breaking the product environment, Without having to have expensive devices with which to make a laboratory to do simulations with GNS3. At the same time, not a purely laboratory environment where there are no problems from the real world. I participate with 1 Node in the project of about a year. One of the problems in the project is 1:1 With the real world – When someone declares you the prefixes you should not announce. Because I'm lazy and I do not write on hand filters ever way, I solved the problem with a rudimentary bash script that generates a prefix-list with the name dn42 and I pour the valid prefixes.

vtysh -c 'conf t' -c "no ip prefix-list dn42"; #drop old prefix list

while read pl
vtysh -c 'conf t' -c "$pl"; #insert prefix list row by row
done < <(curl -s | grep -e ^[0-9] | awk '{ print "ip prefix-list dn42 seq " $1 " " $2 " " $3 " ge " $4 " le " $5}' | sed "s_/\([0-9]\+\) ge \1_/\1_g;s_/\([0-9]\+\) le \1_/\1_g");
vtysh -c 'wr' #write new prefix list

The list of valid predicxes is taken HTTPS:// from wherever the main conveyor + Little modifications on my part to be able to generate prefix sheets. Commands run through Vtysh.

For the 4th consecutive year the free software and hardware conference will be held TuxCon. Personally for me this is the most powerful Plovdiv conference which is held, As it is not only targeted for developers, And the target group is much larger and the audience is very colourful. If memory serves me, I don't think, I've missed an edition so far. This year's edition is especially for me, Since I have a presentation. I'm going to talk about dnsdist and whether it is useful for your infrastructure. The topic I will talk about I chose it myself. I felt the need to show it to the world, Because it is relatively young, And so far I have hardly found anything in it that I do not like. I do not remember when it was the last time I impressed so much new and at the same time work exceptionally well.

As you know CentOS 5 Is EOL (End-Of-Life) of 31 March 2017. Which leads to the following very interesting problem:

# yum update
Loaded plugins: fastestmirror, security
Loading mirror speeds from cached hostfile
YumRepo Error: All mirror URLs are not using ftp, http[s] or file.
&nbsp;Eg. Invalid release/
YumRepo Error: All mirror URLs are not using ftp, http[s] or file.
&nbsp;Eg. Invalid release/
removing mirrorlist with no valid mirrors: /var/cache/yum/extras/mirrorlist.txt
Error: Cannot find a valid baseurl for repo: extras


The problem in short is that the lists of mirrors of CentOS 5 And when trying to get content directly we receive the following rejection:

# curl ''
Invalid release


Generally speaking, the most reasonable idea is to reinstall Tenekiâta with any normal distribution that supports a distributive upgrade. Unfortunately my case is not such and this does not stand as an option on the table. So we had to play a little gypsy scheme. – We start using Vault Mirror. In a moment of completely clear creature and sanity I know, That I will not receive any updates which is not the purpose of the exercise, а искаме просто да има работещ yum с който да инсталирам пакет който ми е необходим. За целта закоментираме всички mirrorlist променливи и добавяме baseurl в /etc/yum.repos.d/CentOS-Base.repo. Накрая получаваме yum repo от вида на

name=CentOS-$releasever - Base

#released updates
name=CentOS-$releasever - Updates

#additional packages that may be useful
name=CentOS-$releasever - Extras

Finally we play a yum clean all && Yum Update. If everything finishes without getting an error we have successfully completed the scheme and we can safely install obsolete packages.
