[expert] Bash prompt

[Bob [EMAIL PROTECTED]]

Hello,

I recently did something to my system (don't know what yet!), and it seems
that a number of things suddenly got changed, like my ethernet card aliases.
No problem, fixed that up.  However, when I log in with Telnet, I get:

bash-2.04$  

Instead of:

[bob@r0 bob]$

(Meaning user BOB at machine R0 in directory BOB)

If I SU, it looks correct.  What got messed up, and what file affects this?

Bob
