I have a fairly clean install of Debian 5.04 on a G5 tower and am having some local network sharing problems. The machine linuxG5 has an address of 192.168.1.4 and when I am logged into that machine I get the following output

silver@linuxG5:~$ nmap localhost

Starting Nmap 4.62 ( http://nmap.org ) at 2010-04-24 10:19 EDT
Interesting ports on localhost (127.0.0.1):

Question:: Why is port 445, 139, 661, etc. not visible over the network, but visible in the local loop? I assume it's a firewall problem, but iptables says

ilver@linuxG5:~$ sudo iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination

Chain FORWARD (policy ACCEPT)
target prot opt source destination

Chain OUTPUT (policy ACCEPT)
target prot opt source destination

So I think my firewall is off? What am I missing?

Thanks!

So it was a problem in my samba setup, smb.conf was pointing to the wrong subnet, hence the ports were not listening.

You can mark the thread as "[SOLVED]" if it's solved.
