I have a system running RHEL4 kept uptodate except for the kernel and
noticed that my NFS exports suddenly couldn't be mounted by clients.
When I logged in and ran sudo to start my investigating, sudo crashed
with a "Segmentation fault". Not looking so good. Interestingly
enough, the problems are related. I upgraded one of my SL43 systems to
SL44 and got exactly the same bad behavior.
If you make use of either wildcards or NIS netgroups in the /etc/exports
file then none of the filesystems listed in there will actually be
exported. Likewise, if you make use of NIS netgroups in
your /etc/sudoers file then sudo with segfault. Ouch!
i.e. in your /etc/exports file:
/space/viewstore @clearcase_machines(sync,rw,no_subtree_check)
or the folowing in your /etc/sudoers file:
User_Alias VOBADM=+vob_administrators
where clearcase_machines and vob_adminstrators are defined in
the /etc/netgroup file on your NIS master server.
Is anyone else wrestling with this?
Anyone know which package is the culprit? Maybe yp-tools-2.8-7 or
ypbind-1.17.2-8?
I've never actually tried to contact RedHat. Has anybody reported a
problem to them and know what the best way to do it is?
