The server isn't responding to the hello, and that's why you're hanging. Make sure the server is doing SSL on that port; many (other) protocols if they receive garbage, which is what SSL looks like, may just keep waiting. Also make sure it's able and willing to do SSLv2; some recent software doesn't. If server accepts only SSLv3/TLS, it may ignore the SSLv2 ClientHello as invalid format and keep waiting for a "valid" ClientHello, which OpenSSL here won't be sending. Try s_client with -ssl3 or -tls1, or at least -no_ssl2 . If that works, change or configure your client app accordingly. ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List openssl-users@openssl.org Automated List Manager majord...@openssl.org
