Topic: Weird Chat messages. Is this an exploit attempt?

[Andy MacDonald]

Hello All.
I've got this a few times in my logs in the last few hours. I've done a few searches on the web for "chat exploits" and variations, but nothing comes up that looks nefarious. Anyone familiar with this?

Chat isn't a network service; it's a program that pppd uses to handle the
dialogue necessary to establish a ppp connection. I suspect that data is the
ppp data itself. Look for readable data on either end of the garbage; that
might clear up what's causing the problem.

Cheers,

Thanks Rich.
In that case, I officially don't care about it from now on.
