pppoe 3.5.1 keeps disconnecting

Hello all,

I'm using RH 9.0 and roaring penguin's pppoe 3.5.1. I removed the
original pppoe software that came with redhat and downloaded and
installed pppoe 3.5.1 directly from the roaring penguin site. I found
this version to be more reliable and easier to setup then RH's version.


I'm able to connect to the internet but after about 1 - 2 hours the
connection gets dropped and I have to reconnect. Here is what I find in
the /var/log/messages when the connection gets dropped:

I have tried tweaking the LCP_interval and PPP_timeout settings. I made
sure that PPP_timeout is 4x as much as the LCP_interval.

example:

LCP_INTERVAL = 20
PPP_TIMEOUT = 80.

but this did not help. What else can I try to keep this connection from
dropping? Thanks in advance.....
