Ok, situation. I've taken over a network with a small number of servers. This network has never had a firewall... I now have firewalls, but am having trouble finding out what ports to open.
I have used "netstat -a -n -o" to try and get a list but the list for each server is massive and I'm not sure I'm using the netstat command properly for this task. If this is correct, then I have to sort through every entry, match it with a PID, then edit a rule on the firewall. Tedious. Is it the only way?
looking on the net I see lots of port sniffers more so than a definitive way to find out "these are your open ports".
Anyone face this where they had to set to up a firewall from scratch on a new network with absolutely no documentation on what's currently in place?
