Red Hat Bugzilla – Bug 90844
NFS and firewalls do not go nicely together.
Last modified: 2007-04-18 12:53:43 EDT
Description of problem:
Due to random ports assignments one has to practically open all ports
in a firewall between machines talking NFS. Some of components involved
can be asked to use fixed ports in /etc/sysconfig/ files but not all of
them. Instead of a long description of troubles and remedies here I'd
rather refer to http://www.lowth.com/LinWiz/nfs_help.html which does that
better than I would. :-) Some words on the subject in release notes
and/or docs also would be nice.
Yes, I know unofficial readings of "NFS" acronym. Still...

Steps to Reproduce:
Created attachment 97680 [details]
Patch to the nfslock /etc/init.d start up script to improve firewall interation.
This patch adds to /etc/rc.d/init.d/nfslock the ability for statd to pick up a
port number from /etc/sysconfig/nfs in the same way that mountd can. This is
helpful for use with firewalls.
