hi,

even after the trying the solutions from google and other forums, my nfs is not working still.
below are the steps which i have tried.
services are running fine at both machines.
firewall has been disabled at both machines.
kept selinux in permissive mode at both machines;
let me know is there a way to fix the same.

[root@station5 ~]# showmount -e 192.168.1.40

Hi,

Do you have a firewall activated?
Do you have SE Linux activated?

hi

Firewall is disabled at both ends.
selinux is in permissive mode.
you can find the same in my above post.

is there anything i need to check apart from this ??
