nfs permission problem
Hello,
there is a strange permission problem with a NFS share on my system.
Somehow, it is not recognized that my user "markus" is in the group
"wir", when I do changes on a NFS mount. If I do the changes local on
the server, everything is fine... Let me go into the details:
That's "me" on the server:
markus@server:~$ echo $UID
1000
markus@server:~$ groups
markus adm mail dialout cdrom floppy audio www-data src video plugdev
users fuse wir
markus@server:~$ grep markus /etc/passwd /etc/group
/etc/passwd:markus:x:1000:1000:Markus Grunwald,,,:/home/markus:/bin/bash
/etc/group:markus:x:1000:
/etc/group:wir:x:1008:markus,bibi
An that's "me" on the nfs client:
markus@haktar % echo $UID
1000
markus@haktar % groups
markus dialout cdrom floppy audio dip src video plugdev games netdev
powerdev scanner fuse nvram smbusers wir
markus@haktar % grep markus /etc/passwd /etc/group
/etc/passwd:markus:x:1000:1000:markus,,,:/home/markus:/bin/zsh
/etc/group:markus:x:1000:
/etc/group:wir:x:1008:markus,bibi
So everything matches.
The nfs share is exported like this on server:
markus@server:~$ grep media /etc/exports
/srv/share/media 192.168.0.0/16(sync,rw,no_root_squash,no_subtree_check)
On the client, it is mounted with the automounter:
markus@haktar % mount | grep /srv/share/media
server:/srv/share/media on /var/autofs/net/server/srv/share/media type
nfs (rw,nosuid,nodev,hard,intr,sloppy,addr=192.168.178.21)
This is the data I want to change, as seen on the server:
markus@server$ pwd
/srv/share/media/pictures/Originale
markus@server$ ls -ld 2009-08-29_1251536114/
drwxrwx--- 2 markus wir 4096 29. Aug 10:58 2009-08-29_1251536114/
markus@server:$ ls -ldn 2009-08-29_1251536114/
drwxrwx--- 2 1000 1008 4096 29. Aug 10:58 2009-08-29_1251536114/
markus@server:$ ls -l 2009-08-29_1251536114/dsc08183.jpg
-rw------- 1 markus markus 2349369 29. Aug 10:55
2009-08-29_1251536114/dsc08183.jpg
markus@server:$ ls -ln 2009-08-29_1251536114/dsc08183.jpg
-rw------- 1 1000 1000 2349369 29. Aug 10:55
2009-08-29_1251536114/dsc08183.jpg
Now I want to change the ownership of the jpg file, on the client:
markus@haktar % chown markus.wir dsc08183.jpg
chown: changing ownership of `dsc08183.jpg': Operation not permitted
Hmm. On the sever:
markus@server:$ chown markus.wir dsc08183.jpg
markus@server:$ echo $?
0
markus@server:$ ls -l dsc08183.jpg
-rw------- 1 markus wir 2349369 29. Aug 10:55 dsc08183.jpg
markus@server:$ ls -ln dsc08183.jpg
-rw------- 1 1000 1008 2349369 29. Aug 10:55 dsc08183.jpg
I was working with nfs for years, but I have not the slightest idea what
the problem is here...
Could you please help me?
