Is it possible to find out which hosts are using a yp server? I want to remove / update an older VM that's acting as a yp-server but it's not clear which clients are out there.
I don't have much experience working with NIS at all, as I came from an LDAP environment. I have a project to move a bunch of clients within a NIS domain to point at a new NIS master server. There's no config management in place, and no real authoritative list of every machine in the domain.
How do I verify that no NIS clients are talking to the old master? I don't see any ypserv log files (the old master is a RedHat AS 3 box...), and AFAIK there's no reliable way to tcpdump for NIS traffic since it uses RPC.
Any ideas?
I am trying to add the mail.aliases map to my Makefile on my NIS/YP server. I have added 'mail' to list of maps to build, and ensured that it is pointing to the correct aliases file (/etc/aliases).
The problem I am getting is that when I run make, I get a "Callback timed out" error like the following:
mail.aliases -> "SlaveNisServer": Callback timed out
The other maps seem to build successfully.
Does anyone have any idea what could be going wrong here?
