Description Michal Jaegermann 2003-05-14 16:38:30 UTC 
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...

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.
