I've got a RHEL5 server acting as a NIS/NFS server, and connected one C5 machine just fine.
I'm trying to connect another, and for the life of me, cannot figure out why NIS won't bind. NFS works fine. ypbind just hangs. I disabled SELinux and the firewall. I just cannot get it to bind.
Ideas?
Thanks.

Check your DNS setup and make sure it is sane.

Hi do you have the appropriate entry in /etc/hosts for ypserv on NIS Server ?
Thanks.

Yep. This is on a small lan - /etc/hosts acts as local dns.
The error is the one when ypinit -s server hasn't been run. I've had two successful runs on 32-bit C5 adding said 32-bit hosts to the network, but this one 64-bit C5 system is giving me the NIS problems. I can ssh, ping, and doing anything else I want. Again, the 32-bit hosts work fine against the server. This one 64-bit machine is simply giving me the NIS headaches.
Thanks for any/all ideas.

if i'm understanding:
-you have a 32bit NIS server that you've configured for your network. -you are not running dns, but are instead using /etc/hosts, and /etc/resolv.conf on your boxes -you have a couple of 32bit clients that can attach to the NIS server, and that you can log against. you can run 'ypcat passwd' on these machines with no issues..
-attaching a 64bit machine as a NIS Client which you've configured as best you can, is giving you errors...
I just had a conversation with a Sr. Redhat Tech support eng, where he was telling me that there might be an issue with my situation that might be related to the fact that the server is 64 bit, and the slave is 32bit...
might not be related.... but hmm...

When you do the ypinit -s, what name do you provide for the server?
It must match the name the server expects, so if the server host name is nis, then you do
ypinit -s nis.domainname

I have successfully done ypinit -s ip_address or hostname on several 32-bit clients and they've all been successful.
I did learn that if I at least have a local account created on the client for the same account on the NIS server, then, with NFS also working, I am able to have pesudo-NIS running.
I tried to disable checksum offloading, rebooted, but it didn't make any difference. I also tried changing the MTU to something like 1470, but that didn't matter, either.
Not sure where to go next...
Can't enumerate maps from <ip> or <host>, depending on what I set as the server. Please check that it is running... will continue to exist until an answer is found...

Why are you running ypinit -s on clients?
You only need to do this if you want to set up slave servers.
NIS clients shouldn't need to do anything special on clients to bind to a server, all that needs to be done is to set up /etc/yp.conf
James Pearson
An interesting sidenote -
Things do work fine on another test setup consisting of C5 64-bit and an Intel NIC. The problem C5 64-bit system has a Broadcom 57xx NIC.
I may opt to change NICs and see if that makes any difference...

I'm at a complete loss as to what is going on. I changed kernels and disabled the video driver, removed the firewire card. NIS refuses to work on this workstation.
Unless this gets figured out, I'm going to simply have to create local user accounts, then let NFS take over.
It would be really nice to figure it out one of these days, as if I can learn the culprit, I'll be better educated the next time I face something like this. I did try tcpdump, but no obvious things popped up.
