Hello, I am having a very strange problem NFS mounting exports from a SLES 9 machine on some (but not all) of my SUSE Linux 10.1 machines. This is a summary of the problem, though there are many more details to be had once I figure out what forum is most appropriate for trying to get it solved. For two out of five 10.1 machines, we cannot NFS mount filesystems exported from SLES 9 machines under a specific setup. On the SLES 9 NFS server, the filesystem is exported as follows (in /etc/exports and applied with "exportfs -a": /home bad101host.domain.name(rw,no_root_squash,sync) When sitting on bad101host, I issue: mount -t nfs sles9host.domain.name:/home /tmp_mnt On sles9host I see "rpc.mountd: authenticated mount request from bad101host" appear in the /var/log/messages. But on bad101host, the mount command hangs, never to return until "kill -9" is applied. (Ctrl-c and lesser kills have no effect.) ========= However, if the filesystem is exported on sles9host as follows: /home ##.##.##.0/24(rw,no_root_squash,sync) [The "#" are replaced with our subnet numbers.] and the same mount command is issued on bad101host, I see the same authenticated message logged on sles9host and the mount succeeds on bad101host. ========= Additionally, we have three other 10.1 machines that successfully mount the filesystems regardless of how they are exported. ------------------- All five of the 10.1 machines have: nfs-utils-1.0.7-36 nfsidmap-0.12-16 [Though I don't know if this is involved.] The SLES9 machines have: nfs-utils-1.0.6-103.23 [And no version of nfsidmap.] Any help, guidance, pointers would be greatly appreciated. -- Anthony Vealé National Snow and Ice Data Center E-Mail: veale@nsidc.org Phone: (303)735-5069
