When I install openconnect client on cento6.5 and try to connect to ocserv(disable sslv3). It shows: attempting to connect to server x.x.x.x:443 SSL negotiation with xxxxxxxxxxxxxxxxxxxxxx SSL connection failure 139933011761000:error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number:s3_pkt.c:339: Failed to open HTTPS connection to xxxxxxxxxxxxxxxxxx GET https://xxxxxxxxxxxxxxxxx/ Attempting to connect to server x.x.x.x:443 SSL negotiation with xxxxxxxxxxxxxxxxxxxxxxx SSL connection failure 139933011761000:error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number:s3_pkt.c:339: Failed to open HTTPS connection to xxxxxxxxxxxxxxxx Failed to obtain WebVPN cookie I want to set ssl version manually.(like "curl -1","openssl -tls1",etc.) But I couldn't find any settings about it in "man openconnect".
