Hello everyboddy!
I have hade great problems with a line that goes up and down
all the time.
The solution to this was to change to bind9 where there
is directives to handle dailed-up connections.
I put the directives
dialup yes;
heartbeat-interval 1440;
in the named.conf files and spontainious dialut died
away completly. So now I can have isdnd running all the
time.
I also hacked a small script that makes a graph from
the logfile, and I run this daily from cron. The
script needs gnuplot ( /usr/ports/math/gnuplot ).
---<the plot script>-------------------------------------
#!/bin/sh
#------------------------------------------------------
#
# Prints a postscript graph of the connectiontimes
# for your ISDN line
#
# gh@raditex.se
#
#------------------------------------------------------
#
# Change to suite your needs
#
# Use the standard format on the accouning file
LOGFILE=/var/log/isdnd.acct
TEMPFILE=/tmp/isdnlog.tmp
PRINTFILE=/tmp/isndprn.ps
# One day back
GRAPHDATE=`date -j -v -1d "+%d.%m.%Y"`
grep $GRAPHDATE /var/log/isdnd.acct | \
awk '{ print $2 "\t0\n" $2"\t1\n" $5 "\t1\n" $5\"\t0" }' > $TEMPFILE
/usr/local/bin/gnuplot <<EOF
set output "$PRINTFILE"
set terminal postscript
set title "ISDN $GRAPHDATE"
set data style lines
set xlabel "Time"
set timefmt "%H:%M:%S"
set ytics 2
set xdata time
set ylabel "traficpattern"
set format x "%H:%M"
set grid
set key left
plot '$TEMPFILE' using 1:2 t 'isdn up / down"
EOF
lpr $PRINTFILE
---<end>---------------------------------------------------
I hope this can help some out there.
