G. Allow TCP Access to port 2401
We need to tell the GNU/Linux box to allow TCP access using port 2401 (49 squared).
Edit /etc/services files and add the following line:
cvspserver 2401/TCP
I also ran LOKKIT and added 2401 to the list of open ports. Red Hat now closes all ports by default. (I don't know if this was absolutely necessary.)
NOTE: I use a Linksys router at home on a small network using a DSL link to access the internet. All I had to do on the Linksys router was tell it that accesses to port 2401 were to be directed to the GNU/Linux box at IP address 192.168.0.5 and my repository was available through the internet.
