Telnet service by default is off, for a good reason. It's not secure. SSH is 
just as easy. All you need to do is make sure it's on for both machine. Run 
the following (as root):

service sshd start

Then, to make sure it's always on after boot:

chkconfig sshd on

Now you can do:

ssh username at host1

There's also scp to securely copy files which might be useful gor you (do 'man 
scp') as part of the ssh package.
