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?

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

/sbin/ifconfig

You don't need the loopback, do you?

I am n ot sure what you are doing but I also havd dsl router with 4
ports and 4 machines (2 are wireless). My hosts file is as follows:
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
192.168.1.100 vulcan vulcan.gateway.2wire.net
192.168.1.101 saturn saturn.gateway.2wire.net
192.168.1.65 cyrus cyrus.gateway.2wire.net

And I can do : ssh vulcan from saturn without problem. Is that what you
want to do?
