I've had an expectation violated recently, and wanted to research whether my expectation was grounded in reality: Given an interface with a primary IP, and one or more aliased IP addresses: When a process opens a connection to another host, which IP address will be chosen as the source address? Steven's just says 'the kernel chooses the IP address and port'. My expectation was that the primary IP address would be used. Is my expectation valid? Is there a spec that describes this, or is it up to an individual OS to do whatever it wants? (I'm sorry to pester this list, as this question isn't actually specific to FreeBSD...) I'm more than willing to do my own research, but a suggestion of useful buzzwords would be appreciated as well. :) Thanks for your time... -- Brian Reichert <reichert@numachi.com> 37 Crystal Ave. #303 Daytime number: (603) 434-6842 Derry NH 03038-1713 USA BSD admin/developer at large
