Description of problem: Cannot connect to a tightvnc server using vncviewer. Java client connects just fine. Version-Release number of selected component (if applicable): vnc-4.0-8 How reproducible: Try to connect to a tightvnc server with vncviewer. Actual results: I get the following output and no vnc window: VNC viewer for X version 4.0 - built Oct 6 2004 08:06:12 Copyright (C) 2002-2004 RealVNC Ltd.

Tue Jan 11 11:39:30 2005 CConn: connected to host colobus.boston.ximian.com port 5901 CConnection: Server supports RFB protocol version 3.130 CConnection: Using RFB protocol version 3.8 Tue Jan 11 11:39:43 2005 main: CleanupSignalHandler called Expected results: A vnc window pops up. Additional info: I install tightvnc client and it connects just fine. This seems like a incompatibility in the RFB version, 3.008 (realvnc) vs. 3.130 (tightvnc).
No, 3.130 means that 3.xxx (xxx <= 130) is supported. The client selects 3.8 and the server is obliged to comply. Note that 3.130 is not an official protocol version in any case: http://www.realvnc.com/docs/rfbproto.pdf When you say "Java client" you of course mean you are using the client supplied to the web browser by the TightVNC server, so it is not surprise that it works. Please attach the captured TCP traffic from running this command before your connection (and control-C it afterwards): tcpdump -U -s 0 -w rfb.pcap port 5901
Here is the tcpdump you asked for. FYI, the client is Fedora Core 3 running realvnc, obviously, and the server is NLD which uses tightvnc. I am also going through a VPN, but that shouldn't make any difference because it works with the tightvnc client.

For some reason this seems to only contain the outbound traffic. Please try: tcpdump -U -s 0 -w rfb.pcap src port 5901 or dst port 5901

Just tried vnc-4_1_1-1.i386.rpm from realvnc.com. Got the same result.
This still only has the outbound traffic. However, what outbound traffic there is shows that the client is acting correctly, and that the server is not.
