ppp has mind of its own

Mon Jan 16 16:18:39 UTC 2006

\I've got a RH9 box set up as gateway here in my office. It uses a dial up 
connection and we use that line for local calls as well so when someone 
needs to make a call - from my ssh I

sudo /sbin/ifdown ppp0

and when the call's done I

sudo /sbin/ifup ppp0

Sometimes though the phone gets dialed out by the computer, even with 
ifdown and the only way I can straighten it out is to unplug the line from 
the modem and start over. This just happened now and here's what is on 
/var/log/messages (no ppp log)

Right in the middle of those log entries where it says

Jan 16 11:00:42 BANYAN wvdial[14324]: NO CARRIER
Jan 16 11:00:42 BANYAN wvdial[14324]: No Carrier!  Trying again.

is where the computer had already dialed out "on its own". Am hoping to get 
some advice on tracing the cause.

Thanks in advance,
