Hi Mark, not sure why you are asking and I don't have an answer, unfortunately.

I am trying to understand why this is required, and what other (non-programmatic) ways to get around this. I am trying to deal with this situation myself.

Two reasons I can think of are: to insure bandwidth to a service utilizing a NIC, since multiple services could all end up using the same link even if multiple links are available. And IPfilter (at this time).

Thanks
Steffen

Hello,

I want to be able write a user space little app which will send packets through a specified interface on a machine with 2 nics(or more). Each nic has a different IP address , but they are on the same network (same netmask).

Is there something which does what "SO_BINDTODEVICE" in linux does ? (as a
setsockopt parameter).
I tried and could not find something like that.

can I do it at all in solaris ?

Regards,
Mark
