Hi,

I've been trying to get my NFS server to work for a few days now, but every time I try to mount any exported path it times out. On the diskless machine I am trying to set up the last kernel message I get is
Code:

nfs: server 192.168.0.3 not responding, still trying


On my mac it doesn't work either:
Code:

$ sudo mount 192.168.0.3:/media/diskless /Volumes/test/
nfs server 192.168.0.3:/media/diskless: not responding
mount_nfs: /Volumes/test: Operation timed out


It's not even mountable on the server itself
Code:

# mount localhost:/media/diskless /mnt/tmp
mount.nfs: mount system call failed
# dmesg
-- snip --
[79270.005858] nfs: server localhost not responding, timed out

Mounting a path that is not exported gives an "Permission denied" error, just as expected.

I haven't found any server-side error messages yet. The only thing that gets logged is this line on every mount attempt:
Code:

rpc.mountd[10611]: authenticated mount request from 127.0.0.1:667 for /media/diskless (/media/diskless)


All the daemons seem to be started, and I don't really now what I could try anymore. Any ideas why it doesn't work? Below you'll find some information that might be useful.

Thanks,
Jan

That is a very old kernel. Does it work if you use a newer kernel (preferably 2.6.38 or newer)?
