Problem
When I ssh login to a CentOS 6 system, it always takes around 30 second to log in.
Solution
CentOS 6 has enabled the reverse-DNS name lookup of IPs by default. To disable in
/etc/ssh/sshd_config
, set:
useDNS no

This is a collection of techical information, much of it learned the hard way. Consider it a lab book or a /info directory. I doubt much of it will be of use to anyone else.
