Start by reading the man page for lanadmin.

If you want more information than this(I.E. Packet sizes and protocals as well as bandwidth), I would recommend that you look at other software that's already working well.

ntop is already developed(not sure about a HP-UX port though), and there are many other packages as well. It's alot of work to re-invent the wheel.

Hi
Thanks for the info .But still not able to find the clue.

Does HPUX has any structure which give info about state of network interfaces such as name Ipacket Opacket collison and errors.if yes how can i use it.

Like using kmem and then use name list ie nlist()(_ifnet) to get all the information of network interface. Just an idea.

Please correct me if i m wrong.

Waiting for ur reply
Thanks and regards

Hi hemant,
There are few libraries you might want to check out which gives you the best result.
getnetconfig this returns a structure called netconfig

and other one is getnetent.
go through the man pages of them i am sure getnetconfig() will give you everything you want.
