- Update with-vnc-key.sh to use only hostname for CN. The gnutls introduces gnutls_x509_crt_check_hostname2 in gnutls/lib/x509/hostname-verify.c#L159 to check if the given certificate's subject matches the given hostname. The function is used by the recent version of libvncclient which will fail to verify the certification if there is a mismatching between the connected hostname and the cert issuer's common name. https://github.com/LibVNC/libvncserver/commit/cc69ee9 So the previous way to generate the vnc server's cert brings a complicated CN, making the client using libvncclient (e.g. vinagre, remmina) hard to adapt the hostname check. It is better to populate the hostname as the common name without extra strings.
