Installing Jenkins on RedHat distributions
After the installation, even though Jenkins was up, I was getting the following exception on logs:
WARNING: Could not intialize the host network interface on nullbecause of an error: centos64: centos64: Name or service not known

Now I don't have the slightest clue about why was jenkins trying to resolve to a server called centos64, but adding that entry to my /etc/hosts file resolved the problem:
127.0.0.1 localhost centos64
It guess it must have used some default configuration and got that network hostname that didn't exist.
