Yes, it only means openssl failed to verify the trust chain of the certificate presented by the client. It means you can't really trust the identity of the server (and all you get is encrypted channel, unless you've been MitM'ed already). > If I try -no_tls1, theerror has printed as below. > error:14077102:SSL routines:SSL23_GET_SERVER_HELLO:unsupported > protocol:s23_clnt.c:697: [...] > Sorry for long mail, but the openssl command above is > /usr/bin/openssl, which is distributed with Ubuntu 12.04.

(Which > doens't support tlsv1) Yes, that's what I would conclude. Sorry but I'm not an expert in this field. While it seems by guess was correct, from there you should proceed by yourself. Start with  and dig deeper.  seems to explain your case. Also note that libcurl uses not OpenSSL but GNUTLS. So I'd try to figure out which defaults your build of GNUTLS has. 1. https://www.google.com/search?q="SSL3_GET_RECORD:wrong+version+number" 2. http://openssl.6102.n7.nabble.com/quot-SSL3-GET-RECORD-wrong-version-number-quot-td8310.html -- You received this message because you are subscribed to the Google Groups "Git for human beings" group.
