Is force_send_socket([proto:]address[:port]) the
function that I need to be
trying to use to meet this requirement? Is there a simpler method that can
be used instead?
I'm not 100% sure about it, but try this:
Every packet on linux goes through a routing table, which includes an
outbound interface. You can specify an alias for each 'local' ip
address. Then - routes are matched beginning with the longest prefix,
so...
- for original interface ethX (for example eth0) create interfaces
ethX:1 .. ethX:N with the source ips assigned to them
- set a route for each interface:
route add -host gw_ip_1 dev ethX:1
route add -host gw_ip_2 dev ethX:2
...
- you may need to add a network, which covers those gateways, so in
case 'add -host' complains:
route add -net gw_ip_1 netmask minimal_netmask_covering_all_gws dev ethX:1
...
In theory it should work ;) I haven't tested it, so you may need to
tweak it a bit (lot)...
