Just another WordPress weblog
Editing spec files is somewhat time-consuming repetitive task. It’s good to add a change log entry every time you rebuild srpm package. One can do it typing it all over the times. Someone can use the maco. I do use this one:
nmap ,cl /%changelog<CR>:r!date +'\%a \%b \%d \%Y'<CR>0i* <ESC>$a David Hrbáč <my@email.tld> -
Simply add this line to you .vimrc file.
Today I have looked again at yum 3.2.8 on Centos 4. I wanted everything to clean up, go back to unittests again. I have backported python-nose and started to clean up the source. Finally I had to make all yum tests python 2.3 compatible. Here is the result:
[root@build-c4-i386 yum-3.2.8]# make test .............................................................................................................................................................. ---------------------------------------------------------------------- Ran 158 tests in 0.889s OK
As you can see, all tests have passed. And as usual packages are available within my testing repo.

http://fs12.vsb.cz/hrb33/el4/hrb/testing/x86_64/repoview/
Today I spent a few hours testing and backporting yum-3.2.8 from CentOS 5.2 to CentOS 4.7. It wasn’t so hard to backport. Most of the time I have spent on testing and searching. Code is patched to allow sets, which are supported in python 2.3 
) and that’s almost all. Final rpms are available for testing here:

Everything works fine. Now it’s time to publish and make some public QA. As you can see, it handles obsolete packages!

I realized that nmap can be used to get info about web server. Informations about servers are easy to read via header. Admins tend to mask actual product or version the web is running on. So, then nmap comes to play with.

During one of my squirrelmail upgrades I have discovered strange behavior. Users were able to login, but only blank page had appeared. I have found this in log:
[Mon Feb 09 18:29:10 2009] [error] [client 89.103.46.115] PHP Fatal error: Call to undefined function load_config() in /usr/share/squirrelmail/plugins/change_sqlpass/functions.php on line 326, referer: http://blabla.blabla.tld/src/login.php
change_sqlpass pluging needs compatibility plugin to run. So here is the patch:

Simple way to remove all but one kernel:
if [ $(rpm -q kernel | wc -l) -gt 1 ]; then rpm -e $(rpm -q kernel | sed '$d'); fi if [ $(rpm -q kernel-smp | wc -l) -gt 1 ]; then rpm -e $(rpm -q kernel-smp | sed '$d'); fi
I have rebuilt OpenSHH5 RPMs for CentOS 5. They seem ) to work pretty well.
