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 :

host  10.10.10.10

where 10.10.10.10 is the IP address of your SLAVE server.

On the SLAVE server (same file) put

host  11.11.11.11

where 11.11.11.11 is the IP of the MASTER server. And that's it :)
