/sbin/init.d/adsl is the script that does the work for
connecting/unconnecting.
On a normal linux installation (everything but SuSE) the directory is
/etc/init.d
since my ISP uses PPTP and not PPoE for the adsl connection I got some
problems
when the connection died. (pppd stays alife,). Therefor I shut down the
connection with adsl stop (which will kill the pppd), wait until pppd has
terminated and then i reconnect.
Probalby you can just bring up your connection without the need to stop and
then start the connection.
So that you can do this:
...
if ! /sbin/ifconfig | /usr/bin/grep --silent $IFACE
then
datestr=$(date +%Y-%m-%d %H:%M:%S)
echo $datestr Interface $IFACE is not up. Reconnecting. $LOGFILE
COMMAND TO BRING CONNECTION UP
echo --- $LOGFILE
fi
Would I be correct in thinking that this script could be modified to also be
able
to monitor, and renew connection via a cable connection, by changing the
IFACE to
eth0, adn the commands to stop the connection, adn restart to ifdown eth0 and
ifup
eth0 ? I have had trouble lately with my isp dropping my connection at work,
and
nobody can get any of their mail until I get in.
Darcy
This would only work when your eth0 interface is down after you were
disconnected by your ISP and I don't think so. Run ifconfig after your
connection died and see if you still got the eth0 interface then. If so the
script won't work.
Or maybe you can still use the script with ppp0 device. My adsl connection is
like this. eth0 is connected to my adsl modem and when i bring up the
connection a ppp-tunnel will be created. This means the ppp0 interface is
brought but (again look at ifconfig this time when the connection is up). This
ppp0 interface is my link to the isp. All communication is encapsulated througt
the eth0 interface. Maybe your cable modem works like this.
If not you could use ping to verify your connection the problem is that if you
send 10 packages with ping and just one is lost ping will return a no zero exit
value. So maybe you're reconnection more often than necesarry but i should work
if test your connection like this
Ping must fail 2 times before we believe the connection is down. The reason
is, that when you send 5 ping packages and one gets lost, than there will be a
non zero exit value and the script would reconnect. If we do the ping twice it'
a little better.
if ! (ping -c 5 nameserver.yourproiver.com ||
ping -c 5 nameserver.yourproiver.com )
then
# connection is - bring it up again
# do some logging

RE: [expert] Show status of adsl connect
Got adsl yesterday and managed the setup. though not using draknet. I
tried draknet first but it did not work. Then I ran adsl-setup and added
a defaultroute in adsl-start. Now it works like a charm.
Problem is, 11 (my provider) cuts the link after 15 minutes
of inactivity and after 14 hours of continous running.
1. I put up a cronjob which sends 1 ping tom my own domain every 14
minutes.
in addition to this job you could also run this script as cronjob which will
check if the connection (ppp0 interface) is still up. if not it will reconnect

Cool! I'll have to modify a bit b/c I don't use the adsl script in the init-tree but the adsl-start script of the pppoe-package. Put it at the end of rc.local and (wonder why) had to put a 'route add default ppp0' behind that (or in ip-up). Otherwise I got a connection but no contact to the nameservers.
