[openssl-users] How to use a specific ip interface while testing TLS/SSL connectivity.

[Scott Neugroschl]

Hi Rajinder,

Have you tried the “socket_transport_name_set” call in your main program?

Thanks Mark for the prompt reply. Absolutely makes sense. Actually, i am on Nonstop HPE servers. There are no internal routing tables or so to say static routes. Environment is different from unix/linux.

From Application perspective, we choose what ip interface to use.

Wondering if we can force the openssl to use specific interface?

Regards.

Hi Rajinder

There shouldn’t be any issues depending on how your host OS is performing the routing to the network the SSL/TLS endpoint is on.

Try a tracerout to the IP to see where it goes, and a telnet IP 80 or 443 to make sure you can connect to the web server.

Hi,

I want to use a specific ip interface (out of several available ethernet interfaces available on my server) to test TLS/SSL connectivity to a remote server.


Wondering if its possible?
