connecting to VNC with a non root user

[Maracineanu, Dan]

Hi,

I would like to start an application on serverX:2 using VNC.
The application owner is a nonroot user (apps).
I've logged on as root on serverX
start vncserver :2
xhost +

logon on serverX as apps
DISPLAY=serverX:2.0
try to launch xterm and receive the following error message:
Xlib: connection to "serverX:2.0" refused by server
Xlib: Client is not authorized to connect to Server
xterm Xt error: Can't open display: serverX:2

What could be wrong?
server IBM AIX 4.3.3

Any suggestions will be apreciated.
Thak you

Dan,

You're creating the Xvnc server as root, rather than as the user who will
actually be using it. Log on as user apps and create the server and all
should work as expected.

Hi,

I've tried this and the result is the following:

Logon as appdev
which vncserver -> /usr/bin/X11/vncserver
vncserver :5

You will require a password to access your desktops.

Dan,

Those errors look like something to do with the Java runtime, not to do with
VNC.
Who are you logged in as when you try to run the xterm?

user is appdev
it seems the error is the result of running xauth

Xstartup file -->

xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
twm &
------------------

if I try to run twm from console as user appdev I receive the same error message:

***@aix3:/home/appdev/.vnc>twm

Hi,
I would like to start an application on serverX:2 using VNC.
The application owner is a nonroot user (apps).
I've logged on as root on serverX
start vncserver :2
xhost +

try `xhost -display :2 +`

Or do `Xvnc -help` and pick the security options, you can provide them to the
vncserver script or hack them in there.

Or do the `xhost +` on a terminal inside the vnc session.

Post by Maracineanu, Dan
logon on serverX as apps
DISPLAY=serverX:2.0
Xlib: connection to "serverX:2.0" refused by server
Xlib: Client is not authorized to connect to Server
xterm Xt error: Can't open display: serverX:2
What could be wrong?
server IBM AIX 4.3.3
Any suggestions will be apreciated.
Thak you

try `xhost -display :2 +`

***@aix3:/>xhost -display :2 +
1346-219 xhost: bad hostname "display"
1346-225 xhost: unknown address family ""
1346-219 xhost: bad hostname ":2"

Post by Corné Beerse
Or do the `xhost +` on a terminal inside the vnc session.

In VNC viewer window:

***@aix3:/etc>xhost +
access control disabled, clients can connect from any host
1346-217 xhost: must be on local machine to enable or disable access control.

So in other words it doesn't work
