[openssl-dev] [openssl.org #4258] bug: s_client -connect option fails on IPv6 addresses

[Markus Wernig via RT]

Hi all

When an IPv6 address:port tuple is given to s_client's -connect option,
the internal parsing of the address/port seems to fail. The port is
taken to be a part of the IP address, and the IP address is shortened by
the first 2 bytes:

# openssl s_client -connect 2a00:c38:10a::1:0:71:443
getservbyname failure for c38:10a::1:0:71:443

Leaving the port empty, results in the same error:

openssl s_client -connect 2a00:c38:10a::1:0:71
getservbyname failure for c38:10a::1:0:71

Verified with OpenSSL 1.0.2e 3 Dec 2015 (Gentoo) and
OpenSSL 1.0.1f 6 Jan 2014 (Ubuntu). Both systems do have IPv6 connectivity.

Kind regards
