Problem opening firewall port

[weedguy]

I have ISPConfig installed on a Fedora Core 4 box. ISPConfig is working perfectly. However, I also want to use my computer as a samba file server. I need to open up a few firewall ports to do this. I used the ISPConfig control panel and tried to open port 137. I restarted the firewall using the control panel. Before and after I did this, I ran nmap and got the following output:

Starting nmap 3.81 ( http://www.insecure.org/nmap/ ) at 2005-08-05 13:54 EDT
Interesting ports on ddnsserver1.hopto.org (192.168.0.10):
(The 1644 ports scanned but not shown below are in state: closed)

993/tcp open imaps
995/tcp open pop3s
2049/tcp open nfs
3306/tcp open mysql
32770/tcp open sometimes-rpc3

Nmap finished: 1 IP address (1 host up) scanned in 0.253 seconds

As the listing shows, port 137 is not open. How can I open up port 137?

Have you installed SAMBA and started it?

Have you installed SAMBA and started it?

Yes, you have to start Samba. You can run

iptables -L

to see which ports are open in the firewall.

Samba is running and working correctly. Also, I am aware of the command iptables -L listing the ports but the installation instructions for ISPConfig instructed me to turn the firewall off. This is why I used the command nmap to show the ports that are actually open.

The ISPConfig firewall is a IPTables firewall.

Yes, I was thinking that you were running the ISPConfig firewall...
