problem with network share and Windows FireWall


Recommended Posts

Posted

Hey

 

I have 2 computers in my home network, one pc is a winXPpro+sp2, the other

is a win2k3 machine

 

on the win2k3 machine I've created a NFS share, using fs.msc.... The problem

is that I'm unable to connect to this share from the winXP machine.... well,

if I turn off firewall on both machines I'm able to connect, so I guess it

is a firewall issue

 

win2k3 machine is domain controller in this network, Active Directory

installed

 

These are the ports I've opened on Windows FireWall in both machines:

111 - both TCP and UDP

1039 - both TCP and UDP

1047 - both TCP and UDP

1048 - both TCP and UDP

2049 - both TCP and UDP

 

Haven't enabled the "File and printer share" on both machines

 

any suggestions?

 

Jeff

Sniff the traffic to find out what ports need to be opened.

Re: problem with network share and Windows FireWall

 

what tools in windows do you recommend for sniffing ports ?

List of ports

 

List of ports

 

I ran LanSpy 2.0 and discovered these available ports on the win2k3 machine

(I run the test from the winXP machine) :

21, 80, 139, 445, 3389

 

Another strange thing is that I've created exceptions for 111, 1039, 1047,

1048, 2049 but LanSpy didn't find them. So that may mean that LanSpy is a

bad tool... or there is a issue in the Windows Firewall on the win2k3

machine

 

The problem is that on the win2k3 machine I've created a share and I'm

unable to connect to that share if firewalls are turned on... But I hope

there can be possible to enable some kind of exceptions that allow having

firewall turned on, and allowing me to connect to the shares from my winXP

machine.. On these exceptions I've specified using my subnet as restriction

(scope), so the ports don't come available for the entire world

 

Any suggestions?

Re: problem with network share and Windows FireWall

 

Sniff the traffic, not ports. You can already find out what ports are open

by running "netstat -an".

 

Load up Wireshark and look at the packets coming in to your server. You'll

be able to determine what ports they're trying to reach.
