Once again, for lack of a newsfeed, I bring my questions to the FreeBSD lists. Sorry for the annoyance. I'm involved in a project where I need to control the source address of a socket used in a connect() call. Basically, the service I need to connect to can only accept one connect from each address, but they'll let us connect from 4 machines. What I need to do is set up a machine with 4 addresses, then open a connection to the server machine from each of the 4 addresses. So far, my initial attempts to use bind() before connect() have been a wash, as bind returns an errno of EADDRNOTAVAIL, regardless of which address I'm using. I was under the impression that bind could be used before a connect to set the source address. Is this wrong? Is there a correct way to do this (needs to be portable to Linux)? Feel free to answer in private email.
