[SunRescue] Quad Port Redundent Internet

[Eric Ozrelic]

Hey, I have both DSL, and broadband cable at my house. I wanted to setup
some sort of redundent internet setup, so that if one of them goes down,
then
the other one will pick it up asap, without having to swap cables, or change
addresses.

I have a few ideas. I have a Osicom Quad port 10/100 ethernet card, that
supposedly can be used in an Ultra, and it supposedly has drivers for
Solaris.
Has anyone every heard of or messed with this card?

I wanted to connect the cable, and dsl to the quad card in my Ultra. Then
using a script, ping an internet IP every 10 seconds or so on each port. If
a port goes out, and the IP can no longer be pinged, it will rollover to the
next available port that is pingable.

I would use NAT on this machine, so all my workstations would just use the
IP
of my Ultra/NAT box for there gateway, and port changes would be
transparent.

Anyone have any ideas or know of any sites that go over this sort of thing?
I
don't believe something like this would be too difficult. I'm just not very
good
at scripting/programming in Unix, so this will be an exciting new learning
experience.

Thanks in advance,

Regards,
