This DHCP is too dynamic

[Janina Sajka]

We used the adsl-setup script to configure the ppp0 device. During that
process, she put in her username and password for the ISP, which is
Earth Link, by the way. 

She definitely connects. She's successfully ssh'd to my system, and
scp'd files from me. I managed to ssh over there once--but then the
session went dead after about a minute.

So, I had her issue :

ifconfig ppp0 |grep inet

several times, about a minute apart. We had a different address every
time.

I supposeit's a kind of security thing, but it sure makes the kinds of
things we here do to help each other out, especially for newbies, very
dificult. Also, it seems to bemucking with ftp and possibly Real Audio.
