Thanks! I understand that part. If there is no inet address on a eth# then i could assume that NIC is free. Coming to second part, what if i find all NIC's already assigned an IP. How do i find if there is a free slot for NIC to be added?

Thanks

If physical site is not a possiblility I guess you look at the server specs and the attempt to account for any/all existing adapters using lspci.

Re: Need to find Free 1 GB NIC Port.

If HP agents are loaded, you should be able to examine the slots on the System Management Homepage. Also, using DMIDECODE would show you what is there, and you might have to cross reference with the box's specs to see how many slots the box has as I think DMIDECODE will show cards that are populated but won't show empty slots...

Re: Need to find Free 1 GB NIC Port.

Here is the Plan i have. Look at the ifconfig -a and find any interfaces that do not have ip assigned (not sure how to handle the bonded ones)..and then look at dmidecode and look at PCI-E which are in available state (used means it is occupied). Is this an acceptable plan??
