SYNOPSIS ssvnc ssvnc [host][:display] ssvnc [saved-profile-name] ssvnc [options] [host-or-profile] ssvnc --help DESCRIPTION ssvnc is a tcl/tk gui wrapper that runs on Unix, MacOSX, and Windows. It sets up an SSL or SSH tunnel to the remote VNC Server and then launches the VNC viewer (either the one provided or another one that you have specified) to use that encrypted tunnel to connect to the VNC Server. The use of Proxies and Gateways to make the connections is implemented. OPTIONS -help, -h Print this help. --help Starts up the GUI as though the 'Help' button was pressed to show the main Help panel. -profiles List the saved SSVNC profiles you have created. A profile is a destination host with specific parameter settings. -list Same as -profiles -ssh Start in "SSH Only Mode". No SSL aspects are shown. Same as running the command sshvnc -ts Start in "Terminal Services Mode". This is like "SSH Only Mode", but simpler and assumes x11vnc is available on the remote side to start and manage X and VNC sessions. Same as running the command tsvnc -tso Same as -ts "Terminal Services Mode", however never let the user leave this mode (no button to switch modes is provided.) Same as SSVNC_TS_ALWAYS=1. -ssl Force the full GUI Mode: both SSL and SSH. This is the default. Same as -ss. -nv Toggle the "Verify All Certs" button to be off at startup. -nvb Never show the "Verify All Certs" button. Same as SSVNC_NO_VER- IFY_ALL_BUTTON=1. -bigger Make the Profile Selection Dialog window bigger. Same as SSVNC_BIGGER_DIALOG=1. -noenc Start off in a mode where a 'No Encryption' check button is present. You can toggle the mode with Ctrl-E. Same as SSVNC_DISABLE_ENCRYPTION_BUTTON=1. Or noenc=1 in ~/.ssvncrc. Selecting no encryption is the same as the vnc:// and Vnc:// prefixes described below. -enc implies the opposite. -killstunnel On Windows, automatically terminate the STUNNEL process when the viewer exits instead of prompting you (same as killstunnel=1 in ssvnc_rc or toggle in Options menu) -nokillstunnel On Windows, disable -killstunnel mode. Same as killstunnel=0 in ssvnc_rc or toggle in Options menu. Note that -killstunnel mode is now the default. -mycert /path/to/mycert.pem Set the default "MyCert" to be /path/to/mycert.pem. Same as -cert. If the file does not exist, ~/.vnc/certs is prefixed and tried. You can also set mycert=/path/to/mycert.pem in ~/.ssvncrc -cacert /path/to/cacert.crt Set the default "ServerCert" to be /path/to/cacert.crt. Same as -ca. If the file does not exist, ~/.vnc/certs is prefixed and tried. You can also set cacert=/path/to/cacert.crt in ~/.ssvncrc -crl /path/to/mycrl.pem Set the default Certificate Revocation List to be /path/to/mycrl.pem. If the file does not exist, ~/.vnc/certs is prefixed and tried. You can also set crl=/path/to/mycrl.pem in ~/.ssvncrc.
