Hi All, I'm trying to get a NFS4 client & server id mapping working right. My client mounts to a couple of NFS4 servers. I want to get it setup so that for just ONE of them, files added to or modified on the server BY my local client, logged in EITHER as my user or root, get written with a specific user/group == "nobody:users" I'm pretty sure that all the magic is done with idmapd config. This is what I put together after reading the docs and a bunch of posts online. Obviously I'm still doing something wrong. On my Desktop I have an autofs mount cat /etc/auto.nfs4 | grep TEST TEST -fstype=nfs,vers=4,_netdev,rw,proto=tcp,async,soft,cto,user,sec=sys,exec,nosuid,nodev,fsc,forcedirectio,rsize=32768,wsize=32768 nas.my.lan:/data/media1 I've got local users of id nobody uid=65534(nobody) gid=65533(nobody) groups=65534(nogroup),65533(nobody) id testuser uid=1000(testuser) gid=100(users) groups=6(disk),0(root),494(serviio),33(video),10(wheel),100(users) id root uid=0(root) gid=0(root) groups=6(disk),494(serviio),100(users),0(root) And a mapping config of cat /etc/idmapd.conf [General] Verbosity = 0 Pipefs-Directory = /var/lib/nfs/rpc_pipefs Domain = localdomain [Mapping] Nobody-User = nobody Nobody-Group = nobody When I create files on the server from my local client as either a normal user or root cd /mnt/NFS4/TEST whoami testuser touch test1.txt su whoami root touch test2.txt Locally, it looks like I end up with "nobody:nobody" ls -al test* -rw-r--r-- 1 nobody nobody 0 Aug 9 10:31 test1.txt -rw-r--r-- 1 nobody nobody 0 Aug 9 10:31 test2.txt On the Server, the export is grep vol /etc/exports /data/media1 10.1.1.0/24(rw,sync,no_wdelay,insecure,no_root_squash,insecure_locks,sec=sys,anonuid=1025,anongid=100) Users are id nobody uid=99(nobody) gid=99(nobody) groups=99(nobody) id testuser uid=1026(testuser) gid=100(users) groups=100(users),101(administrators),1023(http) id root uid=0(root) gid=0(root) groups=0(root),2(daemon),19(log) id 1025 uid=1025(guest) gid=100(users) groups=100(users) and the mapping file is cat /etc/idmapd.conf [General] Verbosity = 0 Pipefs-Directory = /var/lib/nfs/rpc_pipefs Domain = my.lan [Mapping] Nobody-User = nobody Nobody-Group = nobody [Translation] Method = nsswitch [Static] But still cd /data/media1 ls -al test* -rw-r--r-- 1 1000 users 0 Aug 9 10:31 test1.txt -rw-r--r-- 1 root root 0 Aug 9 10:31 test2.txt I'll be the 1st to admit that I'm having a heckuva time understanding this mapping biz! :-/ What do I need to change in my config so i end up with cd /data/media1 ls -al test* -rw-r--r-- 1 nobody users 0 Aug 9 10:31 test1.txt -rw-r--r-- 1 nobody users 0 Aug 9 10:31 test2.txt on this and only this server? I.e., so I can use THIS mapping for THIS server, and OTHER mappings for OTHER servers. Thanks for any help!
