Mount Red Hat NFS Drive

[Drew Lane]

Happy New Year,

I've been trying to mount a hard drive located on my Red Hat 7.2 box
to my YDL 2.2 box, but I keep getting this error:

mount: RPC: Unable to receive; errno = Connection refused

I've tweaked the following files:  

hosts.allow
exports
fstab

I've got NFS running on both machines.

I can NFS mount another hard drive from a different YDL machine.

I can ping the Red Hat machine
I can ssh to the Red Hat Machine
I can telnet to the Red Hat Machine
I can even smbmount the Red Hat Machine when it's running windows.

But I can't NFS mount the Red Hat Machine!

?????????????

Any ideas?
