After the Russians attacked Lithuanian governmental institution websites, pigu.lt, a Lithuanian e-shop (something like amazon.com), announced a security contest.
In time period of one week ( since July 9th till July 15th ) anyone could try and hack pigu.lt, and wouldn’t be sued for that (if he won’t make any real damage).
For anyone who could successfully exploit their website, pigu.lt team would give you 1024 piguLitas ( about 500$ ) discount in their e-shop.

Last night i had a pleasure of seeing nagios scream about one of my mail servers load.
When i ssh’ed to the box the load was at 104, ouch. A quick tail -f /var/log/messages showed me the problem – i’m being DDoS’ed. My screen couldn’t handle all that output – ~500 connections /s, which makes it two-three times more log lines in the maillog ;( Read the rest of this entry »

A few days ago freebsd.lt finally expired and i had a chance of ordering this domain! Hooray!!!!
I don’t really know what i will do with it, but the last owner didn’t do anything at all
Currently, i just redirected it to http://www.lt.freebsd.org – Lithuanian FreeBSD mirror which our company hosts.
In the future, if i will have time and resources, it would be nice to create a freebsd-related website with articles about it in lithuanian (maybe english too?). But i’d need help, as i wouldn’t have much time to manage the website.
Any volunteers to help me out with that?!

I hate when people use #!/bin/bash in their shell scripts!
Today, at omnitel.unix – a lithuanian newsgroup, there was a question “massive nslookups”. A guy said that he has a text file with IP addresses one per line, and asked how to lookup them all.
A few hours later, a guy who’s nickname is ‘bash’ (heh…) replied to the message… i was mad after reading it. Read the rest of this entry »

Today I have finished reading The Book of Postfix – State-of-the-Art Message Transport by Ralf Hildebrandt and Patric Koetter. It took me almost a month to read it, the book has 496 pages, and i was reading it while going to work and back home.
I could say that i am more than average postfix user and know it quite well. I am managing quite big mail servers ( a few million mails per day, >= 100k mailboxes ) and give free support in #postfix @ freenode ( but i always like if i get something in return! ).
I liked the book – i did learn a few things from it, although i don’t know if their up to date, so i will have to check it out. Most useful chapters i found are:
- Chapter 19: A Company Mail Server
- Chapter 22: Performance Tuning
Overall, i did like the book and i will definitely offer it to my friends who want to start with postfix.
I really wish there would be some info on stuff like milters and delivery slots in this book, as i am not familiar with it yet and would really like to read more about it.
I give the book a 9 (because it missed the milters, delivery slots and etc.).
Great work Patrick && Ralf, and thanks Roman123 for sending me the book.

Doh, it’s only the third day i use WordPress and i’ve already filled a bug report.
Today, i created a user ‘alex’ so that i could post with this user, and not ‘admin’ to the blog. And i’ve generated a password and tried to change to it – and boom, error:
ERROR: Passwords may not contain the character “\”.
What the hell? I didn’t use \ in the password! A quick debuging showed that password i posted had been quoted, so if i used abc” it quoted it as abc\” – that’s because i have magic_quotes_gpc turned on. I’ve added a quick stripslashes() on password if magic_quotes_gpc is on and it started to work.
WordPress ticket can be found here http://trac.wordpress.org/ticket/7197
I don’t know WordPress yet, so maybe the patch isn’t correct. Use it on your own risk

A few weeks ago i have found a website which lists expired .lt domains – but, i have found out that it is filtered and semi-automatic, so i don’t like it.
And i thought – hey, i wonder if i can make a site like that, and automatic – so i tried to do it. The same evening i have made the code and run the test website. I’ve told about it on one forum – and most people liked it, so i thought i will make it public. After a few modifications i bought a domain and made the web site public.
If somebody thinks it would be nice to change/remove/improve something in it – please leave a comment!
So – here it is – www.expired.lt

Ah, at last, on Wednesday i’ve received two books. I’ve helped out Kyle Keith with his postfix and amavisd problem and he sent me those books as a gift. Brand new books from amazon!

So, as you see, i’ve decided to start blogging… again.
I don’t know why, but … here it goes
Also, i had to decide what domain to use. Currently i own a few domains:
- fw.lt
- nw.lt
- v6.lt
- elpastas.lt
- braske.net
- datavoid.org
- lameriai.lt
I’ve decided to drop datavoid.org and lameriai.lt as i don’t use them at all anymore.
And, in the end, i’ve decided to use fw.lt (first idea was to make a freebsd-related wiki on this domain, but i’ll use it as my “homepage”).
P.S. i’d like to hear your comments – should i write in english, lithuanian, or both?
