let's start from linux side:
- are you able to mount linux dir on linux itself? - mount localhost:/dir /mnt/tmp_mnt_point
- if it doesn't work, check portmap, lock, nfsd on linux

http://nfs.sourceforge.net/nfs-howto/interop.html - it may help too...

Hello Kamal,

Have you exported the directory to be mounted ? Check /etc/exports on Linux box, or type exportfs -v.

Good luck.

Is the Linux portmapper protected by TCP-Wrappers of iptables? Try "iptables --list" and "cat /etc/hosts.allow" and "/etc/hosts.deny".
