RE: Limit number of users
Are you starting a new VNC session for each user using xinetd or are the users sharing a single VNC session? If it is the former you can configure inetd to run your shell script instead of directly starting a VNC session (running Xvnc). In the shell script you can check if the allowed limit of Xvnc sessions has been exceeded and only if not, run Xvnc. -siva. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Tillman William A CIV USAF 96 CG/SCWDT Sent: Wednesday, February 21, 2007 9:39 AM To: 'vnc-list@realvnc.com' Subject: Limit number of users Does anyone know how to limit the number of people to log on to a particular server using VNC to only 2 users? ___ VNC-List mailing list VNC-List@realvnc.com To remove yourself from the list visit: http://www.realvnc.com/mailman/listinfo/vnc-list Confidentiality Notice This e-mail (including any attachments) is intended only for the recipients named above.

Color Level on slow connections
Will the Color level be adjusted according to the connection speed even if the User picks a specific color level (in the Colours Encoding tab of the Options dialog) before connecting. I thought this depended on whether the AutoSelect option was selected or not. But today I tried reducing the bandwidth between the server and client (using network simulation software), after connecting without any bandwidth restrictions (over LAN). The AutoSelect option was enabled and the initial Color level was 256 colors. Even after the bandwidth was reduced (to about 56 kbps) the color depth did not go down. Before I was selecting the Color depth the initial Color depth automatically selected was 64 Colors or lower for the low bandwidths - so VNC knows that 256 colors is high for the given slow connection. All this was with VNC Free Edition v4.1.2 - Windows client/Solaris server. -- Regards, Siva.

RE: VNC session quits
The vnc server times out idle connections (no keyboard/mouse input) after a pre-set timeout interval. This interval is, by default, an hour. It can be modified by the Xvnc parameter -IdleTimeout seconds. In your case you would have to add it to the xinetd entry starting Xvnc. Refer to Xvnc man pages for more details. -siva. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Arno Schuurs Sent: Monday, October 30, 2006 8:07 AM To: vnc-list@realvnc.com Cc: Marty Kampes Subject: VNC session quits Dear RealVNC, I am new with VNC, so I hope you can help me.

RE: setting server rfb port to non-default - on the vncviewer
John,
vncviewer -geometry 1440x1062 -passwd z ipaddr::4918:19
/dev/null and that worked.
I think the ':19' after the port is immaterial. Try connecting to
ipaddr::4918:abcd or even ipaddr::4918abcd; it works. It makes
sense because you cannot have more than 1 display listening on a single
port (the second Xvnc will complain that it cannot bind to the given
port) unless using inetd.

John,
No, you don't - the syntax you are specifying to your VNC Viewer
(host::port:display) is not valid. The two valid syntaxes are:
Host:port_or_display (display if 0-99, port otherwise) and
Host::port(always port)
i.e. you specify *either* a VNC display number *or* a TCP port number.
VNC display numbers 0-99 are just a short-hand for TCP port numbers
5900 to 5999.
I hate to argue with someone who has a realvnc email but my recent
experience is in direct contracdiction of what you have written:
1).I started my vncserver with options
vncserver :19 -geometry 1440x1062 -name x -rfbport 4918
(I can explain why but not relevant)
Here is the Xvnc process:
Xvnc :19 -desktop xx ... -geometry 1440x1062 ... -rfbwait 12
-rfbauth -rfbport 5919 -fp ... -rfbport 4918
NB the two -rfbport options. - the first (I assume) always
specified,
and the second from my vncserver option. And to show which one took
precedence:
here is netstat output to show which port it actually is
listening
on:
netstat -an | egrep -e 4918|5919
tcp4 0 0 *.4918 *.*
LISTEN
tcp4 0 0 ipaddr.4918 other_ipaddr.34849
ESTABLISHED
2)and now here is the command I used on my workstation to connect :
vncviewer -geometry 1440x1062 -passwd z ipaddr::4918:19 /dev/null
and that worked.
Does that convince you? If not - try it!
