X -query

Gino Pino — Thu, 09 Jan 2003 10:27:33 GMT

Hi.
I have to open an X session on a HP-UX console.
I try with X -ac -query , but it doesn' t work because the routing in Natted.
With raflection X in Windows i can set a parameter where the output have to go, and so i put the natted address and that works.
Somebody know what i can do with HP-UX?
Tanks....

Hello

The commande X -ac -query IP should work.
I m sorry but my english is poor, what do you mean by natted ?

Can you give more informations :
- modele
- do you have a error message on the console or in /var/dt/Xerrors ?
- Can you log on with reflection X ?

Solution:

/usr/bin/X11/X -ac -query

or if using fontserver

/usr/bin/X11/X -ac -query -fp tcp/:7000&

Best regards,
Armin

Tank for respond me.

My problem is when i try to open an X session
from a hp-ux console to a sun solaris console.
The problem is generated only when between these hosts there is one NAT ( network address translator ).
In Windows ( with reflection X ) i skeep this
problem setting reflection on -->Setting-->Networks Settings and defleg Autodetect ...
and i put the IP Address ( traslated IP )of my PC.
How can i do the same with hp-ux ( if is possible )?

Tanks a lot.

P.S.
If there isn' t a NAT everything goes OK

My understanding of NAT is it should be transparent to the remote host, ie the remote system should not know there is any natting going on within the network and therefore recieves a standard IP header.

If someone could confirm this ? then maybe the configuration of the NAT system is at fault here.

fyi I know of no hpux / X utility similar to RX's autodetect utility.

I guess the only other way to trouble shoot this is to examine the xdmcp packets ... a nettl trace and a look at the Xprotocol -details available from MIT website might help ?

I've scanned the network with a sniffer and i can see during the connection with Reflection,
that the ip address ( translated IP ) is in the mit-magic-cookie variable.

then:
My IP is: 192.168.128.xxx ( Win )
My Translated IP is: 10.1.203.xxx ( Nat -> Win)
Sun remote host is : 172.16.97.xxx (Sun)

When an X session is open on sun netstat -a | grep .6000 geve me a list of open session with IP 10.1.203.xxx.6000

I think that reflection during the SYNcronizzation put in the mit-magic-cookie the translated IP.

Anybody knows if this i suppose is correct, and how can i put mi IP translated on the mit-magic-cookie and force to use that,
on HP-UX sistem?

Sorry for my english.
Tanks to all.

fyi MIT magic cookie is enabled via /usr/dt/config/Xconfig :

# Dtlogin*authorize: False

enabled by default under hpux 11.X .... it might be worthwhile disabling it or vice versa : X will need to be restarted though for this to take effect ....
