Just been looking through some servers and seen that the external ip is set up with the full and short names the wrong way round, e.g.:
a.b.c.d myserver myserver.mycompany.org
What sort of problems can this cause, given that nsswitch.conf is configured with files as the primary hostname resolver?
At present it doesn't seem to be causing us any direct problems for us (besides hostname/hostname -f returning the short name), but I need to know how urgent it is that we fix this.
