Re: [Xen-users] Xwindows or Freenx in a guest domain

[Steven Anderson <hikenboot@xxxxxxxxx>]

Greetings!
 
 I tried to get FreeNX working and was getting sigterm 15 error. Which noone was able to help with. I decided to troubleshoot the problem by just connecting thru SSH -Y connection from dom0 to domU. The image for the guest was created in qemu and the system partition was migrated to a raw partition for use with Xen. I have spent two weeks troubleshooting it and no luck. I have reinstalled openssh and its dependents on both domU and dom0 and still no luck at all. I am at my wits end with this problem. I have spent about 12 hours with people from the #linuxhelp #fedora from freenode and irc.oftc.. and noone has been able to help.. They think its a Xen issue but I am not sure. Next I was going to try and get it working from dom0 to the qemu image to see if it made a difference.
 
 Here is the details
 
 trying to setup xnest session to remotely launch xterm (later on I would like to get gnome working remotely)
 
 on the server side I have IP address
 192.168.15.101
 on the client side I have IP address 192.168.15.100
 
 I am not using DNS
 
 I launch the SSHD with the command /usr/sbin/sshd -d -p 1236
 
 It says
 
 debug1: sshd version OpenSSH_4.2p1
 debug1: read PEM private key done: type RSA
 debug1: private host key: #0 type 1 RSA
 debug1: read PEM private key done: type DSA
 debug1: private host key: #1 type 2 DSA
 debug1: rexec_argv[0]='/usr/sbin/sshd'
 debug1: rexec_argv[1]='-d'
 debug1: rexec_argv[2]='-p'
 debug1: rexec_argv[3]='1236'
 debug1: Bind to port 1236 on 192.168.15.101.
 Server listening on 192.168.15.101 port 1236
 
 On the client I issue  xhost +
 
 It says
 
 access control disabled, clients can connect from any host
 
 I type Xterm
 
 an Xterm session starts
  
 In the Xterm session I type
 
 Xnest :1 -ac &
 It informs me
 Could not init font path element /usr/X11R6/lib/X11/fonts/TTF/,
 removing from list!
 Could not init font path element /usr/X11R6/lib/X11/fonts/CID/, removing from list!
 
 I hit <enter>
 
 A prompt appears
 
 I type ssh -Xvvv -p 1236 hikenboot@xxxxxxxxxxxxxx
 
 It tells me
 
 It says a bunch of stuff
 then It says 
 debug3:authmethod_is_enabled password
 debug1: Next authentication method: password
 hieknboot@xxxxxxxxxxxxxx's password:
 
 I type my password
 
 It says a bunch of stuff then it says
 debug1: Recieved SIGCHLD.
 
 and then a prompt appears
 
 I type export DISPLAY=192.168.15.100:1
 
 then I type
 xterm
 
 the last lines on the server say
 
 debug1: session_new: session 0
 debug1: session_open: channel 0
 debug1: session_open: session 0: link with channel 0
 debug1: server_input_channel_open: confirm session
 debug1: server_input_channel_req: channel 0 request x11-req reply 0
 debug1: session_by_channel: session 0 channel

 debug1: channel 2: new [X11 inet listener]
 debug1: server_input_channel_req: channel 0 request pty-req reply 0
 debug1: session_by_channel: session 0 channel 0
 debug1: session_input_channel_req: session 0 req pty-req
 debug1: Allocating pty.

 debug1: server_input_channel_req: channel 0 request shell reply 0
 debug1: session_by_channel: session 0 channel 0
 debug1: session_input_channel_req: session 0 req shell
 debug1: Setting controlling tty using TIOCSCTTY.
  
 on the clients xterm /xnest session it just hangs!
 
 thats it..
 
 thanks in advance for your help and happy hollidays!
