NFS Problem

[Gurumanickam]

hi team

i have nfs server(planet)with /data1 filesystem exported to nfs client(moon).
i have mounted the /data1 on moon.
now i'm logging in with the username dba on moon and creating a file name "guru". if i see the permission of file "guru", it's owner and group is showing as dba.

now i going to the nfs server(planet)logging in with root user and if i see the permission of the same file, it's showing the different owner and group.
What may be the possiblity of this problem?

Dear this verifies if the NFS as reading and gravacao. the ID of equal usuarios DBA estao in the two you scheme?

[john korterman]

Hi,

owners and groups are referred to as numeric values, which are mapped to ids via /etc/passwd and /etc/group.
for example is user no. 1 in /etc/passwd mapped to "root".
The mapping in those two mentioned files are problably different on planet and moon!

regards,

Hi,
the user details on moon and planet do not match.
You have created file "guru" on /data1 on moon as dba.
If you look from planet the numeric id, which is the real identifier of ownership on the file is taken from /etc/passwd on planet.
So for example:
on moon
user dba (id 10) group dba (id 15)
on planet
user fred (id 10) group mail (id 15)
So check your /etc/passwd and /etc /group files on both machines.

Either use/create a common user,use NIS or change permission to 777.

Out of Peter's recommended solutions I would prefer NIS. The user name dba implies database administrator - if this is a db filesystem, I would be very reluctant to make the permissions 777.
