Determining which IP using lanscan

lawrenzo — Tue, 30 Dec 2003 08:57:40 GMT

Hello,

I have run lanscan and 7 cards have been displayed up on the system. I have run ftp using an alias host name and I need to determine which card was used to transfer the data. (HPUX 11.00)

what command can I use.

thanks in advance

Hi,

Do a ping towards the alias name to find the IP address and use the command 'ifconfig lan?' to find the IP address of the lan? card.

'netstat -in' shows up all lan cards (and aliases) with their IP address and subnet...
Changing -in into -i will show them with names instead of IP addresses.

On HP-UX 11.11 the primary lan card is the one that has the same server IP address in column 1 and 2 of the "netstat -rn", and has flag = "UG".

In my case, below, it's lan0 at 0/0/0/0:

Now, however, note that I have two IP addresses on two seperate LANs. You have to know which LAN you used to get from here to there.

lanid=$(lanscan | awk {'print $5'})

ipaddy=$(ifconfig $lanid | awk ('print $2'})

You can add a grep to the first statement to filter your ouput and get it for one lan card.
