Jun 7, 2013 · I was able to fix nobody:nobody ownership issue over NFS on CentOS 6 (server) + 7 (client) with two changes: Make sure the /etc/idmapd.conf Domain parameter is the same on server and client; Server has an actual user with matching UID and GID to the client; then on the client. service nfs restart and remount shares if necessary

V4 relay on the fact, that user names are shared between client and server, while uid/gid cant be different. In opposite, v3 shares uid and gid. Probably, you have to mount with vers=3 to solve your problem. The other possibility to turn off id mapping on the server side: echo "options nfs nfs4_disable_idmapping=1" > /etc/modprobe.d/nfs.conf

Jun 4, 2009 · In NFS v4 you have rpc.idmapd which performs the NFSv4 ID <-> UID mapping on the server and allows you to get more flexible. If you can't use NFSv4, the recommended way to deal with it for NFSv3 is to have your users come from a directory service such as LDAP, or another common database.

Jun 4, 2018 · There is a big confusion with nfs id mapping. The mapping used when a string form principal, like [email protected] , have to be converted into a numeric id and vise versa. However, when you mount with sec=sys, which you obviously do, then all request are authenticated with client's local UID and GIDs.

Aug 23, 2016 · Our new NFS server is a clustered appliance, so availability of the service should not make a difference (see my previous statement about the mounts being accessed more or less constantly). We use host configuration management which should be able to manage either autofs maps or static mounts w/ fstab entries equally well; we also do not expect ...

Sep 7, 2018 · A regular Linux NFS server would do the trick with the following combination of /etc/exportfs options: all_squash,anonuid=xxx,anongid=yyy Citing man 5 exports: all_squash - Map all uids and gids to the anonymous user. anonuid and anongid - These options explicitly set the uid and gid of the anonymous account.

NFS was installed from repo and the test share was mounted. user1@client:~$ sudo apt-get install nfs ...

Jan 7, 2019 · I was then able to mount /var/snap/nextcloud via NFS to the exported directory on the nas, and everything seems to work well. However, I agree with @AndrewHenle -- this approach seems dangerous and insecure, and it would be better to find an approach that mapped the root user on nextcloud.lan system to a non-root user on the nas.lan system.

Sep 11, 2012 · On a Windows 2008 R2 Server (Standard) I need to have a network drive mounted without having a specific user to log on to the machine first. Sort of like an NFS mount via fstab on Unix machines. The network drive will be a share via a BlackArmor (Seagate) appliance (which I presume runs Samba).
