I am administring CentOS 4.4 sendmail server and Squid Proxy server in my office whch was installed by my self.. I need to unstall un wanted deamons and related libs form this machine and only allow to run sendmail and squid. It is very difficult to findout these softwares what to unstall or not. Is there any catolog for software and deamons which gives the functionality of it to the OS. However is there any link to get these information?
