I have a 4-port router/dsl modem, and 4 machines connected. All of my

I'm trying to learn rsync. However, I decided that learning a less
complex program would ease the learning curve. So I'm working with rcp.
LQ has a small tutorial at http://wiki.linuxquestions.org/wiki/Rcp
which states that I can give the computer name. However, it doesn't work:
[mpk@d500 documents]$ rcp info 5bw130:
5bw130: Unknown host
I also tried with its lan ip:
[mpk@d500 documents]$ rcp info 10.0.0.6:
10.0.0.6: No route to host
What's going on here?
1) You do not have DNS or /etc/hosts set up
2) You do not have routing set up correctly, most likely due to
incorrect network interface configuration. Check your network
interface's subnet mask.
I don't know how to set up either of them.
Also, for #2, is that stuff that I'd config on the computer or the router?

It is hard to say without more information. Please post the output of:

You don't need the loopback, do you?

10.0.0.2 is my router.
Also, can you ping 10.0.0.6?
