[Olsr-users] DOT draw Telnet plugin

[John Schultz]

I finally got it working.

I ended up using two scripts, one shell script and one expect script.

The main scrip that controls everything is as follows:
#!/bin/sh

TIMESTAMP=$(date +%m.%d.%Y-%H%M%S)
SERVER='**********'
USER='**********'
PASSWD='**********'

remountrw

./topology.sh > topology-$TIMESTAMP.dot

sed -i 1d topology-$TIMESTAMP.dot
sed -i 1d topology-$TIMESTAMP.dot
sed -i 1d topology-$TIMESTAMP.dot
sed -i 1d topology-$TIMESTAMP.dot

dot -Tpng topology-$TIMESTAMP.dot -o topology-$TIMESTAMP.png

lftp -u $USER,$PASSWD -e "put topology-$TIMESTAMP.png; quit" $SERVER

rm topology-$TIMESTAMP.dot
rm topology-$TIMESTAMP.png

remountro

exit 0

and the second script that actually gets the DOT data is as follows:
#!/usr/bin/expect -f
spawn telnet 127.0.0.1 2004
expect -re "}"
send "\]"
send "quit"


Took me forever to figure out why the script was not logging into the
server, I then realized that I didn't set up forwarding on my firewall
(chuckle). But this does work and ive tested it several times.

Enjoy,
John

There is no "exit command" for the dotdraw plugin... it keeps sending until
you close the socket.
