Hello Guys:

This is more of a personal problem. I work for a University and the Univ has given me an ip address range 135.123.39.2 - 135.123.39.254 for my lab. Every time I bring a computer for the lab, I have to ask the university to add the dns name to the dns server. Recently we have split up within the lab and we are having trouble coexisting. So we want to separate. Now the whole setup is like this

rouetr -> firewall -> switch -> workstations/servers

There is only one port coming out of the the router and going to the my linux firewall (bridge mode) and then to the switch where i distribute all the IP tot he rest of my machine. Now I am trying to understand the University setup. This is a Class B address (135.123.39). But if I wanted to separate within or ask the univ to separate,

1) How they would do it and

2) How can I do it ?

I want to know all my options. I would be glad to provide you with more info if needed

Thanks Smilie

       -n ip  the router IP address on the internal lan

       For  help  with different options: python ipcheck.py -h For supported devices listing  : python ipcheck.py --devices For long detailed help
       text    : python ipcheck.py --help

       Make sure you can write to the current directory for data files and that you always run from the same directory.  The first  time  you  run
       the  script,  you will be asked to run with the --makedat option in addition to any other options.  This will create the data files for the
       hostnames and options your specify on the command line.	You should only do this once.  Subsequent runs should be made without the  --make-
       dat option.

       For  help  with different options: python ipcheck.py -h For supported devices listing  : python ipcheck.py --devices For long detailed help
       text    : python ipcheck.py --help

       Example 1: the external IP is on eth0 of the current machine python ipcheck.py -l -i eth0 username password hostnames

       Example 2: you are using the Linksys routing device python ipcheck.py -l -L linksyspassword username password hostnames

       Example 3: you want to use web based ip detection python ipcheck.py -l -r checkip.dyndns.org:8245 ...

       where ... is your dyndns username password and hostnames.  Hostnames should be comma delimited if there are more than one.
