I have an NIS master and slave set up, and whenever I do something that requires synchronization between the two (such as adding a new user), there are long delays that eventually end in a "Callback timed out" message. How do I fix that? This is with two Ubuntu 10.04 (Lucid Lynx) systems.

on the MASTER nis /etc/ypserv.securenets along with your network definitions put a line similar to :
where
10.10.10.10
is the IP address of your SLAVE server.On the SLAVE server (same file) put
where
11.11.11.11
is the IP of the MASTER server. And that's it :)
