Yum Warning: There Are Unfinished Transactions Remaining, You Might Consider Running Yum-Complete-Transaction First To Finish Them
During the build of a Linux development server earlier I performed a “yum update” to update all of the packages after installing CentOS 5.4. I got busy with other tasks and left the server at work without checking to verify that the update had worked properly. Now after dinner I started to get back to work on the server by installing some new packages via yum and received a yum warning message which I describe in greater detail below along with how to resolve the warning.
CentOS Linux Yum Warning Message:There are unfinished transactions remaining. You might consider running yum-complete-transaction first to finish them.
The program yum-complete-transaction is found in the yum-utils package.
The above message showed up near the top of the output of “yum remove sendmail” and after testing it turns out that the message displays on any yum command that is issued to this server. I assume that earlier when issuing a yum update things did not complete correctly thus leaving some unfinished transactions. Resolving this issue is easy enough though by installing the “yum-utils” package and then running yum-complete-transaction.
iptables -4- States & Connection Tracking
http://alper.web.tr/2009/04/28/iptables-4-states-connection-tracking/
Statefull firewall ne demek daha önce değinmiştik. şimdi iptables’ile bunun nasıl gerçekleştirildiğine daha yakından bakalım.
Statefull firewaling için linux State machine dediğimiz olaydan daha çok tracking machine olarak çalışır ( iz sürme makinası ), Sıksık ikisinin manası birbiri ile karıştırılsada aslında farklıdır. Yazıyı okuyup nasıl çalıştığı hakkında daha iyi bilgi edindiğinizde bunun önemini daha iyi anlayacağınızı ümit ediyorum.
Move Apache domlogs to second disk drive or any where
Its a simple job and recommended appraoch is to stop Apache before moving domlogs so it will bring downtime. Here is how you can do it:
service httpd stop
ps ax | grep httpd (Verify that no httpd process still running)
cd /usr/local/apache
mkdir /home2/apache ( Considering /home2 as your new drive)
mv domlogs /home2/apache/
ln -s /home2/apache/domlogs /usr/local/apache/domlogs
ls -la /usr/local/apache/ (Verify the link)
service httpd start

Install Pidgin 2.6.2 on Lenny
The version of Pidgin that is in the Lenny repositories has some problems. It’s an older version and does not work with Yahoo messenger, usually you can’t get the proper certifcate from Yahoo in Pidgin. I attempted to install it myself using the version of Pidgin for Sid by downloading the files from Debian. I ran into dependency issue after issue and finally decided just to go with backports. This is the easiest way to install Pidgin 2.6 on Debian Lenny.
Using Lenny-Backports you can install Pidgin 2.6.2 on Debian Lenny.

if you are having problems with RPM’s, you can just get the CLI version of WinRar
Alternativley if you are having problems with RPM's, you can just get the CLI version of WinRar directly from www.rarlab.com. Make sure you have Glibc 2.4 though.
# wget http://rarlab.com/rar/rarlinux-3.7.1.tar.gz
# tar xvzf rarlinux*
# cd rar
# make
# make install
Hope this helps.
