Spoofed address VS socket bind?

cheako opened this issue · comments

Trying to use spoofed address to force the use of a specific IP or interface on a multi-homed system... Didn't work.

I'm going to add logic similar to wget's --bind-address and also add --wget-bind-address.

SOLVED: It's just getopt_long(), but I was able to do allot without looking that closely.

I don't understand how argument processing is supposed to work.

I used -c and -d because they were the first(alphabetically) unused. This should be complete and correct, someone with a fork can make a PR out of it.
