I want to set up a terminal server using VNC. This will enable you to work on a remote computer and use your local computer as a display only. For this example I used SUSE Linux 13.1 but it should work same or similar on other distributions as well.

= Procedure =
 
* install VNC incl. the config files for xinetd
 
yast -i xorg-x11-Xvnc
 
* edit /etc/xinet.d/vnc to contain
 
service vnc1
 
{
 
        socket_type    = stream
 
        protocol        = tcp
 
        wait            = no
 
        user            = nobody
 
        server          = /usr/bin/Xvnc
 
        server_args    = -securitytypes=none -noreset -inetd -once -query localhost -geometry 1024x768 -depth 16
 
        type            = UNLISTED
 
        port            = 5901
 
}
 
 
 
* start xinetd
 
xinetd
 
* Start yast -> System -> /etc/sysconfig editor -> Desktop -> Display manager -> DISPLAYMANAGER_REMOTE_ACCESS to yes and restart the display manager service with the [[command]]
 
* rcxdm restart
 
 
 
= TroubleShooting =
 
 
 
== No password configured ==
 
* now I got an error message
 
No password configured for VNC Auth
 
 
 
-securitytypes=none
 
* xinetd re start
 
 
 
== Not a valid vnc server ==
 
;Symptom: When starting vncviewer you get an error message like this:
 
# vncviewer 54.186.202.224:1
 
Not a valid VNC server
 
An [[strace]] delivers a line like
 
read(4, "Unrecognized option: -bla\n", 8192) = 26
 
write(2, "Not a valid VNC server\n", 23Not a valid VNC server
 
;Reason: In /etc/xinetd.d/vnc you have provided an illegal server option, in this case ''bla''.
 
;Solution: Remove the illegal server option from /etc/xinet.d/vnc and restart xinetd.
 
 
 
== You only see a black screen ==
 
;Symptom: You only see a black screen in vncviewer
 
;Solution: Start yast -> System -> /etc/sysconfig editor -> Desktop -> Display manager -> DISPLAYMANAGER_REMOTE_ACCESS to yes and restart the display manager service with the [[command]]
 
rcxdm restart
 
 
 
== root logins are not allowed ==
 
;Symptom: When trying to log in as root you get the error message
 
root logins are not allowed
 
You have set AllowRootLogin=true in /usr/share/kde4/config/kdm/kdmrc or whereever you have to set it
 
;Reason: The sysconfig contains a setting to allow or disallow remote root logins.
 
;Solution: For SUSE, call yast2 -> System -> Sysconfig editor -> Desktop -> Display Manager -> DISPLAYMANAGER_ROOT_LOGIN_REMOTE and set it to "yes"
