Multiple connections on a server

[John Donovan]

I am aware of the virtal interface solution, the task is a four-port lan card with a different ip on each -- 192.168.1.100;192.168.1.101;192.168.1.102;192.168.1.103.

Is this possible on HPUX11.xx running on PA-RISC RP3440?

Thanks,

Each port from the card is visible in the system as a separate lan. Use ioscan -fnC lan to see correct names and set IP's in /etc/rc.config.d/netconf for each interface.

4 separate IP's on the same subnet but on different NIC's is NOT supported in HP-UX.

It might kind of sort of work, but your results will be unpredictable.

A 4 port NIC is real, not virtual.

You need to use different subnets on each port or consider to use APA to "team" the 4 ports to one.

Your problem is that all of these IP's are on the same IP subnet and that is not officially supported although it can be made to work with some restrictions.

Refer to Document UTRANKBRC00011759 in the Knowledge base (if you have a support agreement).

what you can do is ad all the ip's to one port:
INTERFACE_NAME[0]=lan1
IP_ADDRESS[0]="192.168.1.100"
INTERFACE_NAME[1]="lan1:3"
IP_ADDRESS[1]="192.168.1.101"
INTERFACE_NAME[2]="lan1:1"
IP_ADDRESS[2]="192.168.1.102"
INTERFACE_NAME[3]="lan1:2
IP_ADDRESS[3]="192.168.1.103"
if you need more speet you can use apa to trunk the four-port lan.

Thanks for all responses.

We know how to set up the virtual interfaces, but since the application requires a separate connection for each instance and the customer doesn't want them on the same lan port.

We had set up one server by assigning each interface with an IP. This should work for us, but will know for sure after the application is installed.

The knowledge base document explains the "gotcha's", the HP Support stance, and confirmed our set up.

Again, thanks to all.
