I have being tring many commands to open this port for Samba:

iptables -A INPUT ip tcp --sport 137 -j ACCEPT
and
-A INPUT -p tcp -m tcp --dport 137:139 --syn -j ACCEPT
-A INPUT -p udp -m udp --dport 137:139 -j ACCEPT

This is how things look now:

According to Firestarter ports 139 137 445 are open, but I don't see port 137 open here and I cannot get Samba to work, I follow all the steps from http://samba.netfirms.com/. Here is more info when I use nmap:

PORT STATE SERVICE
22/tcp open ssh
139/tcp open netbios-ssn
445/tcp open microsoft-ds

I have spent a lot of time in this and I think I'm able to do it. Any help will be appreciated.
Thanks...

You also got to make sure tht there's nothing thats blocking them to go out via OUTPUT chain as well. (after all every packet that traverse in will go OUT as well)

Can you post your complete script ?

This is my smb.conf file:

[global]
#Global Parameters
workgroup= LAB
netbios name=SAMBAtest
#security= SHARE
encrypt passwords= yes

[homes]
read only= no
browseable= no

[music]
path= /data/mp3
browseable= yes
public=yes
write list= xrgm,gts18,rguisbert

[everyone]
path= /data/everyone
read only= no
browseable= yes

[apps]
"smb.conf" 28L, 410C 1,1 Top

I'm sorry which script are you askin me about, I don't understand. Sorry I'm new to all this stuff. Thanks

You know what; Your firestarter said it correct; you have 137 port open at your box, but you didnt checked it properly; as

with you'll see that 137 is open but it uses UDP instead of TCP.

As 137 UDP port is being used by nmbd (for name registration & resolution) & it is open properly ; the problem you have had in your mind until now is not the actual reason for your samba misbehaviour.(if you were opening 137 port for such particular reason)

you can also check it with & you'll also get confirmed about its usage in association with nmbd.

This is what I got when running the command: nmap localhost -sU

Starting Nmap 4.10 ( http://www.insecure.org/nmap/ ) at 2006-11-13 12:33 EST
Interesting ports on localhost (127.0.0.1):
Not shown: 1484 closed ports
PORT STATE SERVICE
68/udp open|filtered dhcpc
137/udp open|filtered netbios-ns
138/udp open|filtered netbios-dgm

For lsof | grep netbios-ns I did not get an output. Thanks for your help Amit, but at this point I don't know what to do!

So what do you think is the problem here?? I'm confused! Thanks again!

Cucolin; Its your job to tell us the problem & ours to provide a solution to that.
Ok; jokes apart, look you havent told us about your problem yet; The only detail you have mentioned in your posts is tht you cannot get your samba to work// but you got to tell us it in more depth.

Like; Are your users able to see samba box in their network-neighborhood window or not ?
Like are they then further able to see samba-box shares or not ?
& then are they getting any problem in further traversing in these shares or somethin else ?
Or if your samba daemon is dying too early or not ?
Or are you getting any other message(errors) while starting your samba service ?
And you can refer your samba logs for further assitance; Please also post them with ya queries.

Amit sorry about all my confusion here. Ok, will answers the questions above:

1. Yes, users are able to see the Samba box in their network-neighborhood.
2. No, users are NOT able to see the samba-box shares.
3. About the samba deamon dying too early don't know how to tell about this!
4. Not getting any error messages while starting samba.
This is the error message that I get when I try to access the samba box from a WinXP pc:

\XubuntuLab is not accessible. You might not have permission to use this network resource.
Network path was not found.

Since I'm completely new to this, I followed all the steps at: http://samba.netfirms.com/

5. I don't know where the samba logs are located, it is at /var/log/samba I see a log.smbd and log.nmbd, but they are empty files. Please let me know.

Let me know if you need more info. and thanks for your help...
