Hi all, I've been looking for a way to bind the openssl s_client command line tool to a certain outgoing IP on a multi-IP host and all I've found was a thread on how to do that using the library: http://marc.info/?l=openssl-users&m=127166957110771&w=2
Is there maybe some obscure bind option the likes of netcat -s 192.168.5.1 mx.example.com 25 to accomplish this? What I'm trying to do is check the TLS cert on mx.example.com where this MX only accepts connections from a secondary IP of the host I'm coming from, as I would by saying openssl s_client -showcerts -CApath /etc/postfix/tls/cacerts.d/ -starttls smtp -connect mx.example.com:25 I was hoping for was an option such as openssl s_client -s 192.168.5.1 or openssl s_client -bind 192.168.5.1 but I guess not. Did I miss it? Is it just undocumented? Do I have to build a non-vanilla openssl s_client? Is there a way to connect the vanilla client through another tool? Thanks, Mike
