 Posted: Mon Jan 19, 2004 5:22 pm Post subject: Problems mounting NFS share |
 |
|
Hello..
I have a server where i want to share /var/www/localhost/htdocs to another gentoo linux machine. The user ether (a user on my workstation) should be able to edit files in htdocs from my workstation.
In /etc/exports i have:
| Code: | | /var/www/localhost/htdocs/ 192.168.0.2(rw,no_root_squash,anonuid=1000,anongid=100,sync) |
And I'm mounting the share on my workstation, using:
| Code: | # su
# mount 192.168.0.1:/var/www/localhost/htdocs htdocs/ |
Theres no problem edition the files when I'm logged in as root, but when I go back to use the user ether, i get perm. denided. What am i doing wrong, please help :)
Maybe youll need theese informations from my workstation:
| Code: | # id ether
uid=1000(ether) gid=100(users) groups=100(users),10(wheel),18(audio),35(games),80(cdrw) |
I'm out. |

The reason this is no problem for root is that you have specified no_root_squash on the server; otherwise, you wouldn't be able to modify the files as root, either!

Does the UID of 1000 and GID of 100 exist on the server as well? Furthermore, do those user/group IDs have appropriate permissions for the directory you're exporting? If so, I would like to recommend a modification to your entry in /etc/exports as follows:
| Code: | | /var/www/localhost/htdocs/ 192.168.0.2(rw,all_squash,anonuid=1000,anongid=100,sync) |
Of course, there are other ways to deal with the permissions that are possibly more secure, but as long as your LAN is well-controlled this should not pose a concern. If you have the user ether on both server and workstation with identical uid and gid, you could dispense entirely with the squashing and anonuid/anongid.
I hope this helps!

|
|
Hello,
I have another problem to this...
My NFS runs 'fine', Debian Woody server, Gentoo x86 client stations. There's just the problem, that each client hat other uids and gids, so I need to map them correctly.
I have
/home/groover bo(rw,anonuid=1001,anongid=1001) bomile(rw,anonuid=1004,anongid=1004)
in /etc/exports, but when I export directories from the server, the uid/gid weren't mapped.
I still have the uid/gid as they are on the server, uid/gid = 500.
Of course my local user groover has no permissions to write to this export.
Everytime I read about anonuid/anongid in /etc/exports, I read that I have to run ugidd on the client side to get uid/gid mapping work.
In the gentoo package nfs-utils-1.0.6, which I have installed on the clients, there isn't something like /sbin/ugidd .
Perhaps you have an idea for me?
Thanks a lot,
groover
