Confused about DHCPCD

OK I have several windows computers and
a linux computer behind a blue linksys DSL
switch.

Now I run dhcpcd to get the linux computer online.
How do I write the setup scripts for the ethernet
card to keep the ip addresses consistent?

Please point me to helpful documentation because
I am having trouble finding it.

What do you mean by "keep the ip addresses consistent"?

What goes in /etc/hosts?

And do you need to run ifconfig in the scripts?

I'm not sure what you're looking for here. Dhcp normally keeps itself
"consistent" in that it renews the lease part way through the lease time.
Is there a specific problem you're having?

Still not clear on what you're asking for. Are you perhaps trying to
understand how to keep a computers name "consistent", so that when you
ftp, or ssh or ping yourmachine.yourdomain.com, it always sends data to
the same machine on your network, regardless of what ip address has been
asigned to it via DHCP?

The specific problem I am having is that I cannot get
Samba to work properly. I cannnot see the linux
machine from the windows machines in network
neighborhood. I can telnet into the linux machines
from windows machines using ip addresses.

Then your problem has nothing to do with dhcp. Dhcp is used to assign an IP
address. If you can connect with telnet, you've got a valid IP address.
Based on your comment, I suspect you have a problem resolving host names.
If so, that's handled by a dns server or by use of hosts files, which list
the host names and corresponding IPs.

Get name resolution going first, so that you can ping or telnet by host
name, instead of IP address. Then start working on the Samba issues.

Agreed. Without any hostname resolution, or if you don't have a
hostname set on your linux system, samba won't know how to announce you
to the netbios world. If you get your hostname resolution working, then
you can start tackling the samba stuff
