Hi all,
How to check that I am behind a firewall ?. I am still unable to
access Apache CVS so I want check whether the network gateway has a
firewall and is blocking port 2401. Is there any tool for it in Linux
If you are behind a NAT gateway, this is easy to do - just visit a
website like www.myipaddress.com and compare with what you see on your
system.
If you are behind a bridging firewall, this is much more difficult,
and the techniques can vary.
In either case, you could try:
nmap -n -p 2401 cvs.apache.org
to see if someone is blocking you from accessing the site.
