Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: FLTK viewer Group: trunk Status: Open Resolution: None Priority: 5 Private: No Submitted By: Mike Fisk (mfisk) Assigned to: Pierre Ossman (ossman_) Summary: Add -stdio option to vncviewer Initial Comment: The request is for a -stdio option that would cause vncviewer to communicate the RFB protocol over stdin and stdout rather than a TCP connection. We use a plan-9-style stdio method for connecting to vnc servers over ssh (not ssh port forwarding, just stdio). This method uses two scripts (sshvnc and getvncserver) where sshvnc is run on the client launches a vncviewer and connects it to the stdio of an ssh to the server host where getvncserver is run. To improve efficiency and simplify the sshvnc script, I would like a -stdio command line option to the viewer so that one can do the following: ssh remotehost getvncserver -args <> vncviewer -stdio (using bash syntax) I have previously been using the -listen option to vncviewer, but that doesn't work in the new viewer or recent servers (separate bugs are filed for those issues). However allocating an ephemeral port to redirect between the ssh and a vncviewer leads to race conditions and unnecessary resource utilization, so the stdio method would be preferable anyway. We support multi-user servers and these stdio methods are much cleaner and more secure than allocating per-user or ephemeral port listeners and tunneling to/from them. We use ssh since it supports a variety of authentication mechanisms without requiring changes to the VNC protocol or implementations. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=1126849&aid=3477059&group_id=254363 ------------------------------------------------------------------------------ Try before you buy = See our experts in action!
