Nis slave not updating

The first one who can help me, will get another 300 points one way or another!

) "The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years.

This does not change the behaviour of NIS, so I'm still getting the RPC timeouts and the error message "Your NIS passwd may or may not be changed" (when using yppasswd on server-a). But we need for security reasons the file securenets.

I've added a new line in securenets for localhost (255.255.255.255 127.0.0.1) - yppasswd still works fine.
