newbie question (again): samba & windows 2000/98

Post by Maik » Wed, 05 Sep 2001 18:24:55

I know this has been talked about so many times, but I am going to bring
it up as I can't seem to find the right code to fix my problem.

It seems that I am having a problem seeing my internal network since I
put my freebsd box up for some reason.... but that could be a different

Anyways, I want to be able to get file sharing access off my box from my
windows machines, but can't seem to find the correct piece of code... or
procedure that I need to do.

This is my smb.conf file... suggestions... thanx ahead:

# Samba config file created using SWAT
# Date: 2001/08/09 16:19:22
# Global parameters

netbios name = Charmander
server string = Samba %v running on FreeBSD 3.4-Stable
interfaces = ep0 lo0
bind interfaces only = Yes
security = user
#encrypt passwords = Yes
#password level = 2
#username level = 2
log file = /var/log/samba/log.%m
max log size = 50
lock dir = /usr/local/locks
guest account = guest

read only = No
browseable = No

comment = Temporary file space
path = /usr/tmp
read only = No
directory mask = 0775
guest ok = Yes
browseable = No

comment = HTML Documents
path = /usr/local/www/html
valid users = me
read only = Yes
write list = me

#comment = Network MP3 Share
#path = /mp3
#guest ok = Yes

You need to supply more info. Some quick pointers :

- can you connect (ping) from win->freebsd and freebsd->win? If not,
check firewall settings, ....
- You need to put the windows boxes in /etc/hosts.
- add the users, both as unix users and as samba users.
- Anything in the logfiles (smbd, nmbd, windows-machine logs, ...) ?

I didn't look at that yet; check out the points above first.

In general, there is lots of documentation around, although it's
sometimes hard to find what you are looking for.

HTH, good luck,

!== DIAGNOSIS.txt for Samba release 2.2.0-alpha3 24 Mar 2001
Contributor: Andrew Tridgell
Updated: November 1, 1999


This file contains a list of tests you can perform to validate your
Samba server. It also tells you what the likely cause of the problem
is if it fails any one of these steps. If it passes all these tests
then it is probably working fine.

You should do ALL the tests, in the order shown. I have tried to
carefully choose them so later tests only use capabilities verified in
the earlier tests.

If you send me an email saying "it doesn't work" and you have not
followed this test procedure then you should not be surprised if I
ignore your email.


In all of the tests I assume you have a Samba server called BIGSERVER
and a PC called ACLIENT both in workgroup TESTGROUP. I also assume the
PC is running windows for workgroups with a recent copy of the
microsoft tcp/ip stack. Alternatively, your PC may be running Windows
95 or Windows NT (Workstation or Server).

The procedure is similar for other types of clients.

I also assume you know the name of an available share in your
smb.conf. I will assume this share is called "tmp". You can add a
"tmp" share like by adding the following to smb.conf:

 comment = temporary files
 path = /tmp
 read only = yes


Please pay attention to the error messages you receive. If any error message
reports that your server is being unfriendly you should first check that you
IP name resolution is correctly set up. eg: Make sure your /etc/resolv.conf
file points to name servers that really do exist.

Also, if you do not have DNS server access for name resolution please check
that the settings for your smb.conf file results in "dns proxy = no". The
best way to check this is with "testparm smb.conf"


In the directory in which you store your smb.conf file, run the command
"testparm smb.conf". If it reports any errors then your smb.conf
configuration file is faulty.

Note: Your smb.conf file may be located in: /etc
 Or in:   /usr/local/samba/lib


run the command "ping BIGSERVER" from the PC and "ping ACLIENT" from
the unix box. If you don't get a valid response then your TCP/IP
software is not correctly installed.

Note that you will need to start a "dos prompt" window on the PC to
run ping.

If you get a message saying "host not found" or similar then your DNS
software or /etc/hosts file is not correctly setup. It is possible to
run samba without DNS entries for the server and client, but I assume
you do have correct entries for the remainder of these tests.

Another reason why ping might fail is if your host is running firewall
software. You will need to relax the rules to let in the workstation
in question, perhaps by allowing access from another subnet (on Linux
this is done via the ipfwadm program.)


Run the command "smbclient -L BIGSERVER" on the unix box. You
should get a list of available shares back.

If you get a error message containing the string "Bad password" then
you probably have either an incorrect "hosts allow", "hosts deny" or
"valid users" line in your smb.conf, or your guest account is not
valid. Check what your guest account is using "testparm" and
temporarily remove any "hosts allow", "hosts deny", "valid users" or
"invalid users" lines.

If you get a "connection refused" response then the smbd server may
not be running. If you installed it in inetd.conf then you probably edited
that file incorrectly. If you installed it as a daemon then check that
it is running, and check that the netbios-ssn port is in a LISTEN
state using "netstat -a".

If you get a "session request failed" then the server refused the
connection. If it says "Your server software is being unfriendly" then
its probably because you have invalid command line parameters to smbd,
or a similar fatal problem with the initial startup of smbd. Also
check your config file (smb.conf) for syntax errors with "testparm"
and that the various directories where samba keeps its log and lock
files exist.

There are a number of reasons for which smbd may refuse or decline
a session request. The most common of these involve one or more of
the following smb.conf file entries:
 hosts deny = ALL
 hosts allow =
 bind interfaces only = Yes

In the above, no allowance has been made for any session requests that
will automatically translate to the loopback adaptor address
To solve this problem change these lines to:
 hosts deny = ALL
 hosts allow = 127.
Do NOT use the "bind interfaces only" parameter where you may wish to
use the samba password change facility, or where smbclient may need to
access local service for name resolution or for local resource
connections. (Note: the "bind interfaces only" parameter deficiency
where it will not allow connections to the loopback address will be
fixed soon).

Another common cause of these two errors is having something already running
on port 139, such as Samba (ie: smbd is running from inetd already) or
something like Digital's Pathworks. Check your inetd.conf file before trying
to start smbd as a daemon, it can avoid a lot of frustration!

And yet another possible cause for failure of TEST 3 is when the subnet mask
and / or broadcast address settings are incorrect. Please check that the
network interface IP Address / Broadcast Address / Subnet Mask settings are
correct and that Samba has correctly noted these in the log.nmb file.


Run the command "nmblookup -B BIGSERVER __SAMBA__". You should get the
IP address of your Samba server back.

If you don't then nmbd is incorrectly installed. Check your inetd.conf
if you run it from there, or that the daemon is running and listening
to udp port 137.

One common problem is that many inetd implementations can't take many
parameters on the command line. If this is the case then create a
one-line script that contains the right parameters and run that from


run the command "nmblookup -B ACLIENT '*'"

You should get the PCs IP address back. If you don't then the client
software on the PC isn't installed correctly, or isn't started, or you
got the name of the PC wrong.

If ACLIENT doesn't resolve via DNS then use the IP address of the
client in the above test.


Run the command "nmblookup -d 2 '*'"

This time we are trying the same as the previous test but are trying
it via a broadcast to the default broadcast address. A number of
Netbios/TCPIP hosts on the network should respond, although Samba may
not catch all of the responses in the short time it listens. You
should see "got a positive name query response" messages from several

If this doesn't give a similar result to the previous test then
nmblookup isn't correctly getting your broadcast address through its
automatic mechanism. In this case you should experiment use the
"interfaces" option in smb.conf to manually configure your IP
address, broadcast and netmask.

If your PC and server aren't on the same subnet then you will need to
use the -B option to set the broadcast address to the that of the PCs

This test will probably fail if your subnet mask and broadcast address are
not correct. (Refer to TEST 3 notes above).


Run the command "smbclient file://BIGSERVER/TMP". You should then be
prompted for a password. You should use the password of the account
you are logged into the unix box with. If you want to test with
another account then add the -U <accountname> option to the end of
the command line.  eg: smbclient file://bigserver/tmp -Ujohndoe

Note: It is possible to specify the password along with the username
as follows:
 smbclient file://bigserver/tmp -Ujohndoe%secret

Once you enter the password you should get the "smb>" prompt. If you
don't then look at the error message. If it says "invalid network
name" then the service "tmp" is not correctly setup in your smb.conf.

If it says "bad password" then the likely causes are:

- you have shadow passords (or some other password system) but didn't
compile in support for them in smbd
- your "valid users" configuration is incorrect
- you have a mixed case password and you haven't enabled the "password
level" option at a high enough level
- the "path =" line in smb.conf is incorrect. Check it with testparm
- you enabled password encryption but didn't create the SMB encrypted
password file

Once connected you should be able to use the commands "dir" "get"
"put" etc. Type "help <command>" for instructions. You should
especially check that the amount of free disk space shown is correct
when you type "dir".


On the PC type the command "net view \\BIGSERVER". You will need to do
this from within a "dos prompt" window. You should get back a list of
available shares on the server.

If you get a "network name not found" or similar error then netbios
name resolution is not working. This is usually caused by a problem in
nmbd. To overcome it you could do one of the following (you only need
to choose one of them):

- fixup the nmbd installation
- add the IP address of BIGSERVER to the "wins server" box in the
advanced tcp/ip setup on the PC.
- enable windows name resolution via DNS in the advanced section of
the tcp/ip setup
- add BIGSERVER to your lmhosts file on the PC.

If you get a "invalid network name" or "bad password error" then the
same fixes apply as they did for the "smbclient -L" test above. In
particular, make sure your "hosts allow" line is correct (see the man

Also, do not overlook that fact that when the workstation requests the
connection to the samba server it will attempt to connect using the
name with which you logged onto your Windows ...
