comment Bind outgoing SOCKS-server traffic to a specific IP
Yes, but it wouldn't change anything. getaddrinfo only returns parameter to use when creating your socket, and it does not return a bind parameter. What you need to intercept is the socket() or connect() call, to bind the socket to what you want, or to set a firewall mark so that the kernel can pick the preferred source address that you want.

When receiving, the kernel will drop packets if their source address matches one of its own interfaces. You need to unset the accept_local sysctl (or something like that).

comment How do I find the path of socket?
Not all Unix Socket have a path. If the sockets are created by socketpair(), they are not associated with a path.

comment What are main differences between Linux and FreeBSD system from sysadmin point of view?
On the networking side, if you do multihoming, BSD uses a Strong End System model, while Linux uses a Weak End System model. Read RFC1122 for what it means, or en.wikipedia.org/wiki/Host_model

comment Is it possible to force IP source depeding on source ports?
If your server sends packets with the correct source address (verified via tcpdump/*shark, i presume) but your other server receives them with a wrong IP, then there is something in the middle that modifies it, and your server cannot do anything about it.

comment Can we use ICMP redirect message to pass routing information among interior routers in an autonomous system ?
Doesn't ICMP redirects only makes sense on the local link ? If so, the question is setled.
