Public bug reported:
Binary package hint: nfs-common
I wanted to set up a small file server. Since it is not acceptable for
me to have the same UID on all clients I decided to use NFS4 which
should be able to solve that. I started with Ubuntu 11.04 server.
What I did manage is access files (rw) if I have the same UID on client
and server. If they differ I get an error message.
I find that a bit surprising since I have the most basic setup which
should work without trouble.
/etc/exports on the server
/data 10.0.0.0/24(rw,sync,fsid=0,crossmnt,no_subtree_check)
/etc/idmapd.conf on client and server
[General]
Verbosity = 0
Pipefs-Directory = /var/lib/nfs/rpc_pipefs
Domain = local
[Mapping]
Nobody-User = nobody
Nobody-Group = nogroup
/etc/hosts on the server
127.0.0.1 localhost.local localhost
10.0.0.7 benjamin.local benjamin
10.0.0.10 zesi.local zesi
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
/etc/hosts on the client
127.0.0.1 localhost.local localhost
10.0.0.10 zesi.local zesi # Added by NetworkManager
10.0.0.7 benjamin.local benjamin
::1 localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
Hostnames on client and server (hostname command)
zesi benjamin
Dnsdomainname on client and server (dnsdomainname command)
local
But I get strange syslog entries
