Internet Connection Performance Log Daemon
icpld
is a nice solution.
I found no Debian package that logs when internet connections
cease working, although this may be included as a minor aspect
of some Debian package having broader purposes.
I found this package at
http://freshmeat.net/projects/icpld/
Now I can tell when and for how long my ADSL service fails,
so I can better infer internet drop causes (me or Verizon).
Here is an icpld response for one of 8 drops in my ADSL connection last night,
elicited with "icpld -log -m" or from /var/log/icpld.log,
IPv4: Connection down: Wed Jun 9 22:30:03 2004
IPv4: connection up: Wed Jun 9 22:41:09 2004
Down for: 00:11:06
IPv4 Total: 00:26:30
IPv4 connection dropped 6 times.
This particular drop was down for 11 minutes,
while my connection has been down 6 times
for a total of 26 minutes since this daemon started yesterday.
This icpld requires me to choose 2 IP addresses
on the network I want to check --
I chose 2 IP addresses of my IP service provider, Verizon.
The default was to attempt an ICMP connection every 8 seconds,
which I changed to 127 seconds in the configuration file
/usr/local/etc/icpld.conf
I added my own /etc/init.d/icpld to run icpld as a daemon
with each boot, essentially
DAEMON=/usr/local/bin/icpld
if [ -z $(/bin/pidof icpld) ]; then #if icpld not running.
# "icpld -quit" would not remove file missing a running icpld process;
# so if process is not running (as when system crashes),
# then I remove any icpld.pid.
/bin/rm -f ~/.icpld/icpld.pid #created by icpld on each startup.
echo -n "Starting Internet Connection Performance Logging Daemon: icpld"
/sbin/start-stop-daemon --start --quiet --exec $DAEMON >/dev/null
fi
In the configuration file, I set
nobeep=false
cmd4dn=play /usr/share/games/frozen-bubble/snd/stick.wav
cmd4up=play /usr/share/games/frozen-bubble/snd/rebound.wav
so I hear a decreasing tone or an increasing tone
when my ADSL connection goes down or up, respectively.
This helps the mind-meld between my computer and myself.
