This is not the case, since, as I said, the same script with same hw works
fine .. but it's Slackware, and I want to get rid of it and move completely to
debian.

This is probably the cause, but still I don't see why .. except Slack pppd being
slower than debian pppd .. so not catching up with my ISP.
Reading Debian doc about pppd (/usr/doc/pppd/README) suggest me to put a
chat <chat script> && sleep 5
in my script and this fixed it. But .. it doesn't start ip-up properly, since
ip-up does the following:
#!/bin/sh
#
# $Id: ip-up,v 1.1 1996/01/31 21:25:59 alvar Exp $
#
# This script is run by the pppd after the link is established.
# It should be used to add routes, set IP address, run the mailq
# etc.
#
# This script is called with the following arguments:
# Arg Name Example
# $1 Interface name ppp0
# $2 The tty ttyS1
# $3 The link speed 38400
# $4 Local IP number 12.34.56.78
# $5 Peer IP number 12.34.56.99
#
# The environment is cleared before executing this script
# so the path must be reset
#
PATH=/usr/local/sbin:/usr/sbin:/sbin:/usr/local/bin:/usr/bin:/bin
export PATH
# ADDED
# MK @ PC 96/01/25
# say we're on-line
echo "running on $1 to $5 as $4 @ $3" > /dev/console
EXECDIR=/etc/ppp
# routing
route del default
route add default dev ppp0
# send mail
echo 'doing putmail' > /dev/console
$EXECDIR/putmail
# get mail
echo 'doing getmail' > /dev/console
$EXECDIR/getmail
echo "ip-up done!" > /dev/console
# last line
and I get messages from the echo lines, but I don't get any mail popped or sent.
Strange is, if I run ip-up by hand, it behaves properly.
Also, in debian pppd I have to set default route by hand, since pppd informs me
that he refuses to substitute my default route (usually to eth0) to ppp0
I'm using defaultroute in options file, but this doesn't help.
I'm not complaining, when I compare slackware to debian. In all machine I have
installed (up to now, more than 10) debian behaves generally better than Slack,
so I'm happily moving all machine to debian. I just want to know what I'm doing
wrong here, since probably it's my fault. Thanks to all the folks who made and
still make debian so good!
Any help is welcome
Thanks in advance
> b) use "TIMEOUT" chat commands, "passive" or "silent" pppd options.
I'll try them
