I just tried this, but I didn't achieved to make the client successfully negociate an ssl session with my proxy. Here is my proxy server command line: openssl s_server -key /etc/pki/tls/private/localhost.key -cert /etc/pki/tls/certs/localhost.crt -debug -accept 443 Here is my client command line: ~/.juniper_networks/network_connect/ncsvc \ -h beria.zarb.home \ -u rousse \ -r smi \ -f /etc/pki/tls/certs/localhost.crt I'm attaching the proxy output. The certificate/key pair used here has nothing to do with the actual juniper vpn, but the hostname in the CN matches the one used in the client command line. I may eventually get a copy of the original certificate if needed, but I'm not the sure this is the actual problem. Sorry if I'm missing something obvious here, it's a bit beyond my own technicals skills. -- BOFH excuse #59: failed trials, system needs redesigned
