Hi,

I don't understand one point on NFS.

I have 2 machines : A (server) B (Local machine)
In both case, I have created a user called 'user1'

I Mount the server on the local machine

local machine:
mkdir /mnt/backupuser1
chown user1 /mnt/backuser1
chgrp user1 /mnt/backuser1
chown 700 /mnt/backuser1

*On the server, I have
RW,no_root_Squash on the /home/user1

If I mount the folder :
mount 192.xxx.xx.xx:/home/user1 /mnt/backupuser1 -> fine

But any folder created on /mnt/backuser1 WILL NEVER BE FROM user1,
but a
number 507 (for instance)

Why User1, who wants to write into a folder owned by user1, cannot
create files BELONGING TO user1 ????

thanks for your help

Hey,

From what I understand from what you are saying, it is probably that
user1 has a different uid/gui on each system. See your /etc/passwd and
the third/fourth fields. These should be the same. This is part of the
reason a lot of systems implementing NFS, also implement NIS!

Hi Johnny,

Thank you for your reply.
I've created another user : user2 with the same name, same password,
same ID
I don't use any NIS server (I just try to inmplement it.. it doesn't
work. I will investigate)

But the only problem is that:
*Owner, group are OK
* But on the server, rights are 700
If I create a file or folder, from the local machine. it will be 744 ????

Any idea why ??

Cheers
No problems!

Hum. Can't say for sure, but check the umask of each user on each
system. (type in 'umask'). That may be it. Other than that, check 'man
5 exports' for export options that may revolve around this. But, a
umask of 0022 will actually give 644 for files, and 755 for directories.
It does sound like your umask has been changed.

I found it.
When I created the user with the right Id, it create the group with the
wrong Id.
the deal is to create the group first with the correct ID and to create
the user ID with the ID
then -> OK !!

Thanks again!


Ah, so it was back to my original statement - have similar uid/gid between systems. Is that what you mean by 'the right id'? I typically break away from the RH model (new gid for every user) and put all users in gid-100, users. Makes it a bit easier to share files. :)
