I haven't seen this, but I have seen a variety of other issues with loading VncViewer.jar through the built-in HTTP server. I finally tracked them all down, and the cause was that, for whatever reason, the Java plug-in had cached an old version of the TigerVNC Java Viewer (which is also called VncViewer.jar.) When it tried to load that viewer from the cache, it would briefly display a dialog asking me to validate the TigerVNC self-signed key, which confused me to no end, since I couldn't figure out where it was picking up that key. In the long term, it might be prudent for me to rename our viewer to avoid such issues in the future, but at least for now, please try clearing our your JAR cache (this is in the Java preferences. On my machines, at least, it's in General->Settings on Windows and under the "Network" tab on Mac.) > b) Once loaded, I get the java vncviewer popup with Server field and > buttons for 'options', 'ok' etc..

No, :1 is correct. 5801 is the HTTP port, so that's what you enter into your browser. The VNC connection uses port 5901, however, which corresponds to display :1. > c) If I change anything in the Server field, then click Options, it also > closes/crashes silently.

Has that behavior changed since 1.1? I suspect not. index.vnc is loading the viewer through an <APPLET> tag. If there is another way that it can be called that would force the plug-in to be installed (possibly an <EMBED> tag), I'm willing to entertain the notion of changing index.vnc, but I don't have time to fool with that myself. If this doesn't represent a regression, then it's not something I can fix right now. > Moreover when called from the address bar, the server vnc log shows: > 06/08/2012 12:22:11 httpd: get '' for yyy.yy.yy.yyy > 06/08/2012 12:22:11 httpd: defaulting to 'index.vnc' > 06/08/2012 12:22:11 httpd: get 'com.turbovnc.vncviewer.VncViewer' for > yyy.yy.yy.yyy > 06/08/2012 12:22:11 httpProcessInput: open: No such file or directory > > which is probably incorrect. Not sure why that would happen unless the browser is sending an incorrect GET request. I haven't seen it, and I'm using Firefox (but not the same Java plug-in as you are.) I am really strapped for time to debug this, so any help that the community can give is greatly appreciated. ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
