Samba problems with Windows clients

[kam]

I am simply trying to share /tmp with all the computers on my LAN with Samba. The samba server is the only Linux box I have right now, and it connects fine to itself. The problem is the WinXP clients give this error:

\\192.168.0.118 is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions. The account is not authorized to log in from this station.

Ok, here is my smb.conf:

# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options (perhaps too
# many!) most of which are not shown in this example
#
# Any line which starts with a ; (semi-colon) or a # (hash)
# is a comment and is ignored. In this example we will use a #
# for commentry and a ; for parts of the config file that you
# may wish to enable
#
# NOTE: Whenever you modify this file you should run the command "testparm"
# to check that you have not made any basic syntactic errors.

Have you added a user via smbpasswd?

[cowanrl]

First and foremost, you need to un-remark the line that says:

encrypt passwords = yes

You must use encrypted passwords with Windows computers.

I would also un-remark the line right below it that says:

smb passwd file = /etc/samba/smbpasswd

As michealk stated, be sure you have created your Samba users with:

smbpasswd -a username

Another common problem is a firewall running on the Linux box that is blocking the Samba traffic.

Check those and see if it helps.

[Lojan]

Make sure the names of the WKGRP or Domain are the same.
What version of linux are you on? Did you restart the daemons?
Did you check the permissions for the dir you are trying to access?
I only skimmed thru but I did not see a "any" user in this file. I have no trouble with XP/2000 and Samba 2.2.3a or other ver.

[Lojan]

Oh, I see your using RH 7.3. Above will apply. I had it up in minutes after inst on RH 7.3, ( so I know of no issues). If you still have trouble, try Webmin. It can be very heplful.

[kam]

Thanks for helping. I think the un-encrypted passwords was the problem. But now I get a prompt for a username and password, and none of the users in /etc/samba/smbusers work.

Also, I want to just use a generic username for everyone that connects on the LAN, if that's possible.

[cowanrl]

If you want everyone to be able to connect to your Samba server without using a username and password, you need a very simple smb.conf file. Heres one that I use in that situation:

# Samba config file

[global]
workgroup = workgroup
security = share

[public]
path = /public
guest ok = yes
writeable = yes

With that file, everyone has write access to the "public" share no matter what username and password they log in to their Windows/Linux box with. If you want just read only access to the "public" share, then change the writeable = yes line to read only = yes.
Of course, you can change the workgroup name to any you like. You can also change the share name and the directory you share out. In your case, you could call the share tmp and share out /tmp.
