iptables - the home/small office routers do not do port blocking on
the local network.

You can find the ports used for most services in /etc/services.

portmap came from portmap-4.0-126.96.36.199 on Fc-6. But you will not
need it for rsync - you can do rsync over ssh, and it is a much
better way to do things. The standard r* commands such as rcp,
rlogin, etc were designed when networks were much safer places. They
tend to be a security risk now days. Using rsync over ssh is a way
Also, if you are going to use commands like rcp, I believe you need
to have xinetd running on the target machine. And the stock install
of xinetd has just about everything turned off. You can manage the
services controlled by xinetd with chkconfig just like other
services, or by editing the files in /etc/xinetd.d.
Do not meddle in the affairs of dragons,
