RE: [expert] NFS permissions
Just to finish this one off - never could get that export to mount again. In the end I decided that I'd like to change the filesystem it was using anyway, so copied the data, made the partition again, copied back and mounted it under a different mount point. Now it exports just fine. Beats me what was wrong. cheers Brian On Fri, 2002-12-06 at 00:26, Bill Shirley wrote: > I don't know if it will fix it, but try re-booting after removing > the entry. > > Bill > > > > -Original Message- > > From: [EMAIL PROTECTED] > > [mailto:[EMAIL PROTECTED]]On Behalf Of Brian Parish > > Sent: Thursday, December 05, 2002 6:48 AM > > To: [EMAIL PROTECTED] > > Subject: RE: [expert] NFS permissions > > > > > > Thanks for that Bill, but removing the entry from rmtab made no > > difference. > > > > regards > > Brian > > > > On Thu, 2002-12-05 at 14:15, Bill Shirley wrote: > > > Look at the files in /var/lib/nfs and edit the one that has the > > > incorrect entry (rmtab, I think). > > > > > > Bill Shirley > > > > > > > > > > -Original Message- > > > > From: [EMAIL PROTECTED] > > > > [mailto:[EMAIL PROTECTED]]On Behalf Of Brian Parish > > > > Sent: Tuesday, December 03, 2002 6:15 PM > > > > To: [EMAIL PROTECTED] > > > > Subject: Re: [expert] NFS permissions > > > > > > > > > > > > showmount just showed everything exported to everyone.

Re: [expert] NFS permissions
I'm seeing a similar problem: when I'm a member of the group, it only works sometimes (not very often), if I'm the owner, it works all the time. Strange. Worked fine under 8.2.

Re: [expert] NFS permissions
showmount just showed everything exported to everyone. I have now removed the /data export and rebooted everything to see what happens. After this: # showmount -e server Export list for server: /public (everyone) /home/brian (everyone) and some more # showmount -a server All mount points on server: 192.168.0.253:/data 192.168.0.253:/home/brian 192.168.0.253:/public and some more /data still shows up on the -a list (but not on the -e list) after having been removed from exports and the server (and clients) rebooted. ...and of course if I put it back in exports and attempt to mount it, I get the same permissions error. Explicitly adding hostnames or networks in exports makes no difference. Seems like the /data export has been somehow corrupted in a way which persists between reboots. Is there some sort of cache on disk somewhere that needs to be flushed? I imagine that if I remounted the /data partition under another mount point and exported that, everything would work, but that's just avoiding the problem rather than understanding it, so I'd like to persevere for the moment. thanks for the interest!

Re: [expert] NFS permissions
Check using "showmount -e systemname" and see which files are expported to what hosts. Seems like its having problems with perms.(but u said others look same way and they work?) Let us know what u find out. Otherwise add /data hostname(rw),hostname(rw) _Thanks Richard --- Brian Parish <[EMAIL PROTECTED]> wrote: > This evening I found an export from my server no > longer available. > > # mount -a > mount: server:/data failed, reason given by server: > Permission denied > > The server log shows: > > Dec 3 23:50:51 cnc-server rpc.mountd: authenticated > mount request from > 192.168.0.253:709 for /data (/data) > Dec 3 23:50:51 cnc-server rpc.mountd: getfh failed: > Operation not > permitted > > The line in /etc/exports says: > > /data (rw) > > Permissions and ownership of the directory are as > they were and > identical with other exported filesystems.

I was about to say that the anonuid and anongid seemed like the problem,
but I don't think so because "root_squash,no_all_squash" means "convert
all access by user root to this anonymous user, but not anybody else".
The "mapping=identity" is not documented in the exports man page, nor is
it in /usr/share/doc/nfs-utils-{version}/*, so I can't say with impunity
what it's doing.

ls -l -d will show you the attributes like this:
[root@fiji ~]# ls -l -d pvmgmake
drwxr-xr-x8 46664users4096 Apr 29 12:20 pvmgmake/
[root@fiji ~]# chmod u+s pvmgmake
[root@fiji ~]# ls -l -d pvmgmake
drwsr-xr-x8 46664users4096 Apr 29 12:20 pvmgmake/
But I don't think that's your problem. I'm about out of ideas here.
I'll think on it over the weekend.
Blue skies... Todd

Re: [expert] NFS Permissions on Mandrake 8.2
Hello, Didn't know about /var/lib/nfs/xtab, so it isn't what I expected. Only familliar with fstab. This xtab must have been automatically generated by something. $ cat /var/lib/nfs/xtab /home/kmcgladr/images mabeline.localdomain(ro,async,wdelay,hide,secure,root_squash,no_all_squash,subtree_check,secure_locks,mapping=identity,anonuid=-2,anongid=-2) /home/kmcgladr/images mabeline.localdomain(ro,async,wdelay,hide,secure,root_squash,no_all_squash,subtree_check,secure_locks,mapping=identity,anonuid=-2,anongid=-2) - I don't know how to check the suid bit. I do know how to set it, but not how to test for it. from the server: $ id jennifer uid=502(jennifer) gid=502(jennifer) groups=502(jennifer),100(users),501(kmcgladr) from the client $ id jennifer uid=502(jennifer) gid=502(jennifer) groups=502(jennifer),100(users),501(kmcgladr) - No, I'm not running quotas (to the best of my knowledge). - Using diskdrake /home is ext3 /home/kmcgladr/images is listed as "linux native". Would that be ext2? I initially tried setting this up using the right-click "Share" menu item (in Konqueror). Only after that did not work did I attempt to configure NFS, based on the NFS-howto at the Linux Documentation Project. The manuals that shipped with the Power Pack didn't go into anywhere near this much detail. Is the source of my problems that the images volume is using another filesystem? And does that "share" menu item work for other end users? As for Samba, I'm already running it so VMWare has access to the host filesystem. I'm trying to not run it on my real network card in order to prevent any configuration conflicts.

Is it what you expected? If you run 'exportfs -r' does it stay the same? I don't expect this to solve the problem, just making sure it's consistent. What is the suid bit set on that directory? Put the user in the same groups on both machines. Are you running quotas? What filesystem is /home? If it comes down to it, I suggest you: 1) make a directory in / and make it owned by you 2) put a symlink in your home dir if you like that points to it 3) export THAT directory You know you do have another option.
