Opening TCP ports

[Clart]

How can i open a specific port (9100) to allow communications through it?

If i used netstat -a, i can see that the required port is not active. I've tried going through windows firewall exceptions without success.

Depends on your connection. If your using an internet router you will have to do it on there.

Its nothing to do with the router. The port was open, I install a microsoft patch, and now the port is blocked.

Urm. Does the Firewall configuration not let you open it?

Which software firewall are you using?

The windows firewall is disabled as default on our desktop. I've put an exception in (not sure whether it looks at these if the firewall is disabled?) but its still not showing as open.

anyone?

seems odd if the firewall is turned off and the port is open on the router. Uninstall the patch see if it makes a diff?

works ok if the patch is uninstalled, however its a corporate requirement to have it installed. DOH

The only thing I can think of that uses 9100 is HP printers

What are you trying to use it for?
