Problems with SAMBA

Hello,

We have a problem with our samba sever.

Every user that connects to samba, on the server appears as "nobody". The fs is writeable, but users can only create new files but not delete or modify them.

Every user appears in /etc/samba/smbpasswd (but not mapped to nobody in /etc/samba/smbusers).

What can be a problem?

Thanx.

Re: Problems with SAMBA

Hi Alex,

There are many different ways of configuring security in Samba.

What have you got for the security parameter in smb.conf ?

Cheers,

Rob

Hello Rob,
the issue is that smb.conf was not changed.

smb.conf attached.

Re: Problems with SAMBA

Ok, I'm going to go with the assumption that users are accessing the 'public' share with 'Guest' access.

If the users aren't properly authenticating, and being mapped via 'smbusers' to a Unix user, then the permissions are going to be all over the place.

You've not defined a specific 'guest user', so they get to use 'nobody'.

I'm picking that 'nobody' doesn't have permission to write to '/appl/public'. This is why you're having issues.

A few ways around it.

1) Ensure that everybody authenticates properly and has a mapped unix username in '/etc/samba/smbusers'.

2) Set up a guest user properly for the 'public' share, ensuring it has UNIX write permissions to '/appl/public'.

.. Well, they're basically it come to think of it .. ;)

Shalom Alex,

Mah Shalomchah?

security = domain

This will not use the smbpasswd file

To complete integration with windows domain:

system-config-authentication

Use toe GUI to join the domain, you will need a windows admin password to do this.

or change security=user and then the smbpasswd file will start to get used.

Re: Problems with SAMBA

Hi,

I take it things have worked in the past...

Did the Windows guys change anything on the domain controllers ? Maybe a mixed mode Active Directory domain got changed to native mode...

Re: Problems with SAMBA

Hello all and thanx for the replies.

Changing all config files will probably solve the problem and if there is no other chose we'll do it. The weird thing that it stopped working early this morning without any changes that I'm aware of.

We'll dig a bit more with current configuration and then probably will change the configs and maps files.

Re: Problems with SAMBA

Hmmm. Nothing changed on Linux. Functionality stopped working.

Blame the Windows or network guys!

Re: Problems with SAMBA

Another thought...

Maybe the computer account for your Samba server got disabled or deleted.

See whether you're still part of the domain with

# net rpc testjoin

Re: Problems with SAMBA

After many tries all suggestions that I found failed to work ....

Since it's RedHat 7.3 "server" with 30GB of data on it, files were copied to another file server and this one will be reinstalled with Fedora 6 tomorrow.


Thanx for the replies,
Alex.

Re: Problems with SAMBA

shalom again Alex,

May I suggest CentOS 4 instead of Fedora 6. Fedora is not production quality code in my opinion. CentOS meets the same price criteria and is a repackage of AS 4 from Red Hat with the trademarks removed.
