Problem with nfs mounting


I have two machines physics1 & physics2 running fedora core 8. I have connected them via ethernet ports. The PINGcommand and also network monitor shows they are connected. In physics1 from nfs server window I have added a folder /root/desktop/tanuj to share. Then used the exportfs command showing files are exported. In /etc/hosts.allow I have added the IP addresses of one another in both machines. From Service-firewall I have allowed nfs. nfs, nfslock, netfs are running. I have stopped iptables. Now when I want to mount the filesystem from physics2 it displays "permission denied".

Plz help me !!

Thanks in advance.

Also, I've gotten that error message often when I forgot to actually start the NFS server on the host machine. It's not exactly the most intuitive of error messages.

also use

exportfs -v
rpcinfo -p

to check the nfs server side (run them on the server)

rpcbind and portmap are running on both the machines. exportfs -v shows the exported directories. also showmount -e command also works. when iptables was running, I had the message for mount command no route to host. when I stopped iptables, the mount command shows permission denied.

plz help me

What are the contents of your /etc/hosts.allow and /etc/hosts.deny files, because it seems like the client computer is on the deny list from the error messages you are getting.

mountd: 169.254.251.90
statd: 169.254.251.90

Try not using tcp_wrappers (comment them out) to see if it works. If it does you know that it's something in one of your files.

Also keep in mind that you probably want to add portmap to the /etc/hosts.allow file...

How does your /etc/hosts.deny file look like?
