Re: [SLUG] Continuation of PPP woes.

Sorry but i've missed the inital post of this thread but the following 
may help with keepalive stuff.
It's what I do with a permanent modem connection. You could adapt it to 
suit yourself.

cd /etc/ppp
ps ax | fgrep pppd | fgrep -v fgrep > /dev/null || /usr/sbin/pppd
run this through a cron job every five minutes or so and it will check 
whether your connection is up.

Not sure but it looks to me like something's deliberately killing the 
connection. Have you got it set to 'ondemand' by any chance? this would be 
a bad idea for most people's ADSL since we're not time charged.


Also, generally speaking make the connection profile simple and write a 
keepalive script along the lines of:-

#!/bin/bash
while [ 0 ]; do
# can we reach something that's usually reliable
OK=`ping -c5 -w1 mail.isp.com.au`
if [ "x$OK" = "x" ]; then
# no? are we sure?
# try some other thing pretty reliable
OK=`ping -c5 -w5 ns1.isp.com.au`
if [ "x$OK" = "x" ]; then
# still can't reach it 
# ensure the connection is killed off
adsl-stop &
sleep 30
# if adsl-stop got stuck, kill pppd to help
killall pppd
sleep 5
# kill with extreme predjudice to be sure
killall -9 pppd
sleep 2
# fire it up
adsl-start &
fi
fi
# wait 5 mins before checking again
# while testing you can kill 
sleep 300
done
# never gets out of this loop

start the script with:-
/usr/local/sbin/keepalive >/var/log/keepalive.log 2>&1 &
EG in /etc/rc.d/rc.local 

I usually get quite elaborate with my keepalive scripts that automatically 
switch between ADSL & modem dialup backup.

[SLUG] Continuation of PPP woes.

[[EMAIL PROTECTED]]

G'day all...

I'm still having some PPP woes. PPP doesn't always reconnect properly upon
reboot - which then causes squid to fall-over - and sometimes PPP falls
over by itself and doesn't manage to reconnect. If it was just for me, it'd
be ok, as I can fix it - but its for an organisation I volunteer for, so it
causes drama when I'm not around and they can't access the internet. I need
to create a solution so that it automagically corrects itself, or the fault
is prevented from happening. At this stage I'm not sure where the fault
lies. (Eg. The line itself, SwiftDSL or our server.)

I tried putting "MAXFAIL=0" into the options file for the device which
someone else suggested. (Sorry, can't remember who, but thanks for their
help.) Unfortunately this has only helped marginally, and the problem
persists.

Attached is a cut down version of the /var/log/messages file from the
machine. (IP addresses have been blanked out.) I've tried to diagnose the
fault myself, but I'm not really that au-feaux (sp) with PPP - I'd
really appreciate a hand on this one.

Many thanks and all the best.

Mike Kraus
