OpenSSL s_server works without error if my client sends to localhost but not if it sends to the hostname of the machine. (Other than a name error because I have not re-done the server certificate.) I am calling that a totally satisfactory outcome as it works for me for testing.
I consider this issue closed (although not technically resolved). Thanks for your help and patience.

That says &d is not a valid "service" (which in TCP means port). And it isn't. It looks like some calling code was supposed to replace &d with a real value, probably a decimal number, but didn't. > From: owner-openssl-us...@openssl.org > [mailto:owner-openssl-us...@openssl.org] On Behalf Of CharlesTSR > Sent: Monday, August 13, 2012 9:15 AM > I have exactly the same problem as > http://old.nabble.com/s_server-and-gethostbyname-failure-error > -td14675962.ht > ml > http://old.nabble.com/s_server-and-gethostbyname-failure-error > -td14675962.ht > ml > .
