What version/distribution of linux are you running? With my setup the
outstanding network traffic usually timesout within six minutes. What changes
have you made to the diald.conf, beyond what it takes for you to log in. My
diald.conf looks like this:
#
# diald.conf for anathoth
#
# Select the demand dial rules you want
# Bring the link up for anything, timeout in seconds. Use this for
# when the dompute has its own phone line
accept any 300 any
# Use the filter file that comes with diald. This can be a bit drastic,
# so use the filter below
# include /usr/lib/diald/standard.filter
# or use the filter that brings the link up for use on a line shared with
# a phone
# include /etc/diald/phone.filter
# stuff to set up the diald connection
device /dev/ttyS1
speed 115200
lock
mode ppp
# We may get another terminal server, thus use
# 'dynamic' and do not tell PPP the IP number of the other end
# For use with gated, comment out the 'dynamic' option, and
# set remote to be the same as local
dynamic
local 10.0.0.1
remote 10.0.0.2
netmask 255.255.255.252
pppd-options asyncmap 0 user !bchiodini remotename gnc
# ipcp-accept-remote
# impulse 300,0,0
defaultroute
modem
crtscts
connect "/usr/sbin/chat -f /etc/ppp/pppchat -r /etc/ppp/connect-errors"
redial-timeout 10
fifo /etc/diald/gnc.ctl
ip-up "exec /home/bchiodini/bin/netmail"
# >> /tmp/netmail.log 2>&1"
# restrict 9:00:00 17:45:00 1 * *
# or-restrict 9:00:00 17:45:00 2 * *
# or-restrict 9:00:00 17:45:00 3 * *

# or-restrict 9:00:00 17:45:00 5 * *

The accept any 300 any rule will cause the link to go down in 5 minutes of no
activity. I think the default was 420 seconds with the original diald
distribution. There was some debate about the netmask, it probably should be
255.255.255.255. Are you running IP masquerading for any PCs running windows?
If so turn browse master off on those machines. There is no traffic evident
about Windows browsing, however.
BTW: I'm running redhat 6.0 with the 2.2.12 kernel, and my ppp options file is
empty.
