Telnet

[Brian Clark <brianj ais ais-gwd com>]

Hi guys:

I have an easy one for you all, I'm sure, but I can't seem to find an
answer anywhere in the HOW-TOs.
I set up an account for a user, and I want to be able to let them telnet to
my linux machine.

I Dial-in to an ISP via PPP in linux, and my IP address is a dynamic IP
address.

When I, or this user, try to telnet to my linux machine, I get "connection
lost."
We are telneting to my machine's ISP assigned dynamic IP address (such as
user60.XXX.XXX, and I have also tried the exact numerical address).

Is there something that I am missing here? I'm not trying to set up a
dial-in server, I just want to be able to telnet to my Linux box when it is
connected to the Internet.

Thanks -

Brian

P.S. I get the feeling that there is a security related reason as to why
this isn't working (duh?), so what are the pitfalls if this is enabled? :)
