StofaNet

A collection of scripts which signon to StofaNet (Danish ISP) from a Linux box.

System V Init Signon
GUI Signon
Telnet Signon
Browser Signon

If you have a dynamic IP address you might also be interested in visiting DynDNS.

NOTICE!

StofaNet now offers an Always-On service, which somewhat deprecates this collection of scripts.

System V Init Signon

This is a SysV Init script. It is especially useful if any of the sysvinit started daemons need internet access (e.g. ntpd).

## HEADER...

# UserName
USER="<username>"
# PassWord
PASS="<password>"

CURL=/usr/bin/curl

test -x "$CURL" || exit 1

NAME=`basename $0`
set -e

signon() {

   URL="http://signon.stofanet.dk"
   URL="$URL/signon.php?user=$USER&pass=$PASS"

   if test "$1" = "log_af"
   then
      URL="$URL&log_af.x=0"
   fi

   $CURL -s $URL |\
   grep 'Du er nu logget' >/dev/null
}

case "$1" in
   start)
      echo -n "$NAME: Starting ISP connection... "
      signon log_paa && echo OK || echo FAILED
      ;;
   stop)
      echo -n "$NAME: Stopping ISP connection... "
      signon log_af && echo OK || echo FAILED
      ;;
   *)
      echo "Usage: $NAME {start|stop}" >&2
      exit 1
      ;;
esac

exit 0

Download script: stofanet.sh

To install the script as a sysvinit service; rename it to /etc/init.d/stofanet.sh and add it to the runlevels (notice the dot at the end),

update-rc.d stofanet.sh start 50 2 3 4 5 .

or if, for some reason, you are not running a Debian based distribution,

for runlevel in /etc/rc{2,3,4,5}.d
do
   ln -s /etc/init.d/stofanet.sh $runlevel/S50stofanet.sh
done

This is the GUI of a Tcl/Tk script. The script monitors /proc/net/snmp for outgoing connections and only signs on when needed. After the specified idle timeout it signs the connection off. This is very useful when paying per minute uptime.

Telnet Signon

This is a telnet based signon; kind of a poor mans Expect script. This technique could probably be useful in other similar situations.

## HEADER...

# UserName
USER="<username>"
# PassWord
PASS="<password>"
# SignOn server IP
IP="192.168.30.2"
# SignOn server port
PORT="259"

if [ -z "$1" ] || [ "$1" != 1 -a "$1" != 2 -a "$1" != 3 ]; then
   echo "Usage: `basename $0` 1|2|3"
   echo ""
   echo "   1 = signon"
   echo "   2 = signoff"
   echo "   3 = status"
   echo ""

   exit 1
fi

# Telnet closes the connection as soon as its standard input is exausted,
# therefore the delays are added. This is a poor mans 'Expect' script :-)
(  echo $USER; sleep 1
   echo $PASS; sleep 1
   echo $1   ; sleep 1  ) |telnet $IP $PORT

# EOF

Browser Signon

This is by far the most boring form of StofaNet signon! Make browser bookmarks pointing to the following URLs; The first URL signs you on, the second signs you off.

http://signon.stofanet.dk/signon.php?user=<user>&pass=<pass>
http://signon.stofanet.dk/signon.php?user=<user>&pass=<pass>&log_af.x=0
