I have CentOS servers 5.5 and I see that the Xinetd is not install on any of them. Do you think it will be wise to install xinetd or not? These are production systems.
Xinetd is a service that manage internet connection type. It's a version more securised than inetd.
Xinetd is often used for monitoring (nagios, cacti, zabix, etc...)
Like ewwhite said, the install of xinted depend of what you do with your server. I did installed it on my servers, but on those where i don't need it 24/24, 7/7 I just stop it, and on the other (that are critical and need to be monitored), the service run 24/24 7/7!
hope that'll help you.
