[lug] pppd dropping after connection

[Elyse Grasso]

In the process of switching ISPs to frii.com. Trying to log in using wvdial. 
Things connect far enough that I'm given an ip address, then it announces 
that pppd has died (once with error code 13, once with error code 2) and that 
it is redialing. The redials don't get as far before they fail

In /var/log/messages, it seems to get to a line that says 
 Connect: ppp0 <--> /dev/ttyS1
sometimes followed by 
 Remote message: Request Denied
 PAP authentication failed
before it bails.

The successful connection to my old ISP goes on from there with  lines about 
compression modules, default routes, ip and dns addresses, etc.

FRII says the connection is being authenticated or I wouldn't see the message 
about the ip address in the command line window (which is confusing when 
compared to the message log). Is it possible that it is actually the 
compression negotiation that is failing sometimes? 

Any suggestions for ways to track this down? 

Thanks
Elyse
