Problem with xhost

Leon_17 — Tue, 01 Apr 2003 05:54:52 GMT

Hi there,
I am trying to start vnc on system boot-up.
In the startup script I run "xhost +" before I start vnc. While the startup process runs I get the display, but when the process completed I lose my display. It looks like I lose the xhost, I have even tried to start it with nohup.

Can someone please help?
Leon

xhost + for that session.
For permanent entries
Just try entering the hostname to which you are giving access in
/etc/X0.hosts
single hostname per line.
check the man pages of X

Well just in case this is NOT related to xhost lets check around for any errors reported ... anything in $HOME/.vnc/:#.log ?

fyi I don't need to run xhost to get vnc to work on my hpux workstation when connecting to NT etc ...

What else is in the xstartup file ?

Also if you find an error check out the following, http://www.uk.research.att.com/vnc/faq.html

I've found it resolves 99.9 % of problems encountered.

Failing that attach your vnc xstartup file and I'll give it a try if I get time.

More info:
I am still trying to get it to work with /etc/X0.hosts, but no joy.
I am sure it is something to do with xhosts. After boot I run "xhost +", su to a user and then I can run xclock, for example. At this time vcn is in raw mode.

Hi,
I just want to know if "/etc/X0.hosts" is still valid in hp-ux 11i?
I also had a look on VNC fag's, but I still have a problem with xhost.

Hi

from man xhost on my itanium

DIAGNOSTICS
For each name added to the access control list, a line of the form
"name being added to access control list" is printed. For each name
removed from the access control list, a line of the form "name being
removed from access control list" is printed.

FILES
/etc/X*.hosts

SEE ALSO
X(1), Xsecurity(1), Xserver(1), xdm(1)

ENVIRONMENT
DISPLAY to get the default host and display to use.

BUGS
You can't specify a display on the command line because -display is a
valid command line argument (indicating that you want to remove the
machine named ``display'' from the access list).

The X server stores network addresses, not host names. This is not
really a bug. If somehow you change a host's network address while
the server is still running, xhost must be used to add the new address
and/or remove the old address.

since /etc/X*.hosts is still referenced and is used then yes it is supported

Out of interest your startup script .... does it contain su in it at all ?

If yes please be aware that there are 2 forms of Xauthorisation ... host based and user based. Host based = Xhost and yes it's still valid at hp-ux 11.x

Users based as in .Xauthority files see man Xauth

let us know whether the XO.host file creation works/fails ....

Why not just disable authentication in Xvnc and dispense with xhost?

One of the arguments to Xvnc is -ac, which disables authentication.

If you are using the vncserver script, then it would be something like:

vncserver :10 -geometry 512x512 -ac
