how do I enable telnet or ssh access?

[Jason N. Price]

I have a debian install running the 2.4.2 kernel.  I want to allow external 
telnet/ssh access, but am not sure how.  I apt-get'ed ssh and telnetd, but 
don't really know where to go from here.  If anyone could help me out, I"d 
appreciate it.

Thanks.
