You put the program on a host and tell it to scan networks (eg. 192.168.17.0/24) or tell it to traceroute to a particular host, then it draws up a map of the intervening networks and known hosts. It can also do network monitoring etc. Iirc, it's available from within apt as 'scotty'. Enjoy, foo -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?

Thanks Marty
I Forgot to mention that the network has routers. The main objective
is to understand the network better, and have some kind of visual aid,
like a map with the machines labeled.

Naim, this may or may not be helpful but I wrote this bash script a while
ago to establish which ip's were active on my class C network:
The code is:
#!/bin/bash
pingEm()
{
echo "preparing pings"
for((i=1;i<255;i++))
do
echo "ping -c1 192.168.0.$i > $$/$i &" >> pingEmAll.$$
done
echo "start pinging"
chmod +x pingEmAll.$$ && `./pingEmAll.$$`
}
findEm()
{
for((i=1;i<255;i++))
do
awk '/64 bytes from /' $$/$i > ans
awk '{ print length($0) }' ans > len
if [ `more len` ]
then
echo "$i is on the network"
fi
done
}
mkdir $$ && pingEm
findEm
rm -r $$ & rm pingEmAll.$$ ans len
echo End of story
The output looks like this:
$ ./findIps
preparing pings
start pinging
1 is on the network
3 is on the network
7 is on the network
160 is on the network
240 is on the network
End of story

Mapping a netwok
hi, Consider you have a network that you know nothing about. if you have traceroute results to and from many hosts, theoretically and map could be drawn to visuallise the network using common intersections. I need a map, and if possible a report on each machine. All i want to give the software is the IP's of the machines. If packets go through IP's i did not include in my list, I also want to know about them. Looked around but found but didn't really find anything helpfull. Help appreciated, thanks -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
