Hi,
I've had a server running FC2 for a while. I recently upgraded the kernel to
2.6.8.1, and then the NFS server stopped working.
I only get a 'Permission denied' on the client side, but the server writes a
'rpc.mountd: authenticated mount request from ...' in the message log.
I've tried al kinds of kernel options without any luck. I've also tried
2.6.8, 2.6.9-rc4 and 2.6.9, but the only kernel that works is the
2.6.5-1.358 which comes with FC2. However, the client can run both FC2 stock
kernel and 2.6.9 and still connect to the server (when run with kernel
2.6.5-1.358).
Some config info:
/etc/exports:
/rootfs 192.168.1.0/24(rw,sync,no_root_squash)
/etc/hosts.deny is empty, /etc/hosts.allow: ALL:ALL
Does anybody know what the problem is ?
TIA,
Geir Rastad

I had a similar problem when replacing the RedHat kernel on Enterprise 3 Update 3. The problem was that the RedHat nfs-utils package didn't work properly with the vanilla kernels (even though it's version 1.0.6, it's a very much patched version of 1.0.6). After replacing the nfs-utils package with a vanilla 1.0.6, things worked fine.

Would it be possible to narrow down which patch exactly from the redhat rpm caused the problem? --Bruce Fields ------------------------------------------------------- This SF.Net email is sponsored by: Sybase ASE Linux Express Edition - download now for FREE LinuxWorld Reader's Choice Award Winner for best database on Linux. http://ads.osdn.com/?ad_id=5588&alloc_id=12065&op=click _______________________________________________ NFS maillist - NFS@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/nfs ^ permalink raw reply [flat|nested] 6+ messages in thread

Et voila! If you download the FC2 srpm you can see the list of patches that distinguishes their version from stock nfs-utils-1.0.6. It might be useful to figure out exactly which of those patches it is that causes the problem. --b. ------------------------------------------------------- This SF.Net email is sponsored by: Sybase ASE Linux Express Edition - download now for FREE LinuxWorld Reader's Choice Award Winner for best database on Linux. http://ads.osdn.com/?ad_id=5588&alloc_id=12065&op=click _______________________________________________ NFS maillist - NFS@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/nfs ^ permalink raw reply [flat|nested] 6+ messages in thread
