I've got a setup where I run nfs over ssh on several distros, and it's been working like a charm on suse, mandrake, redhat 7-9 etc, but I've been unable to get it to work on CentOS.
First I set up ssh portforwarding using:
/usr/bin/ssh root@<remotehost> -L 250:irc.dynip.no:2049 -f sleep 60d &
Then I mount using the following params in fstab:
localhost:/somedir /somedir nfs rw,tcp,hard,intr,port=250,mountport=251 0 0
I can telnet to port 250/251 and it answers like expected. I can also see the packets travelling through the tunnel using tcpdump.
However, if I try to mount the dir (mount -a), I get this error:
mount to NFS server 'localhost' failed: server is down.
Sniffing on port 22 when running the mount command, nothing happens. It kinda seems like it ignores the port/mountport options.
Any ideas?
