In what sence ??

The script I actually didn' t write myself I just got it out of the readme
of the module and added what I needed it to do to it and changed some of the
values.

Now all this is based on unix systems..........

the one thing needed is net::telnet wich can be optained from cpan.org...

It basicly is an inline telnet client for perl....

The one problem with getting values from scripts is that you will need to
get 4 values it doesn't matter if the last 3 ones are 0...

So what I did is have a script on the target doing a :

netstat -i |  grep eth0 (this will display all info on interface 1...
then I do an echo of 2 sting values and 2 times I echo 0 wich looks
something like this...

2345 (bytes in)
54321 (bytes out)
0
0

no mrtg will take these values as it expects them and put them in the log
file and will generate the graph from it....

ANd on the four values as you look at your log files you will see 5 rows
with one incrementing the first ... and one 4 changing with the input
data...the top one of the list is the one the graph is based on and is a
calculation of the disference the otheronce down are  the differences
between the old one and the new one....(that is probably the easiest way of
seeing it, if I am wrong on that one someone please correct me there)

Hope this clears it up a little ?
