X11 help wanted

[Yoji Atsumi]

Hi folks,

I heard from a gentleman named Pete who offered:

                

> In the /etc/gdm/gdm.conf file, change the line:
> DisallowTCP=true
> to 
> DisallowTCP=false

> Then restart gnome or reboot. You should be okay.

I followed his advice and all is well.
Many thanks, Pete.

A postscript:
After restarting the machine U, I, naturally, tested it from
R as before by getting onto R with the following:
  ssh -X -l yoji R
then
  xclock &
which worked.  But with "DisallowTCP=false"
I can do it without -X flag on ssh command as well.

Regards,

Yoji

Hi folks,

I just started using ubuntu 9.0.4.  I think I have pretty much all
I wanted.  Except...

I can't get X11 display to come my ubuntu.  For clarisy, I will
call the machine I am talking about (running ubuntu 9.0.4)
U.  I can issue "xclock" command from U and the clock comes
to the screen.  No problem.

Now, I ssh to a different host, running redhat, and I will call
this machine R.  Here's what I have done:
On U,
  I issue "xhost +"
On R,
  I export DISPLAY variable as xxx.xxx.xxx.xxx:0.0.  Then issue
  "xclock" command
What I get on R is:
  Error: Can't open display: xxx.xxx.xxx.xxx:0.0
Of course, nothing comes to U's screen.

Would somebody please advise me as to what cure there is,
what stupidity I have
 committed, etc?

Regards,

Yoji
