Re: RH Linux 7.3

Ben,

That is much, much better!

First of all, the command line that you gave is incorrect:

XWin.exe -screen 0 1024x768x65536 -query linux.address.here -from my.address.here


The x65536 is in error.  You should instead be using the following (you don't have to specify a size if you want the window as large as possible):

XWin.exe -screen 0 1024 768 -query linux.address.here -from my.address.here


Or:

XWin.exe -query linux.address.here -from my.address.here


Also, try the -nodecoration parameter, you might like it (it prevents 
the window border from being drawn):

XWin.exe -nodecoration -query linux.address.here -from my.address.here


As for RedHat 7.3, you most likely have to enable XDMCP, which is 
disabled by default.  Read the answer to FAQ question 4.9:

http://xfree86.cygwin.com/docs/faq/cygwin-xfree-faq.html#q-mandrake-8.1-xdmcp


You said something earlier that indicates that you may have already set 
the [Xdmcp] Enable option to True.  If that is the case but you still 
cannot connect, then I would guess that you need to restart ``xdm'', 
which you can do as root by dropping to run level 3, waiting about a 
minute, then returning to runlevel 5.   In fact, are you even in 
runlevel 5?  You can find out what runlevel you are in by running the 
``runlevel'' command:

[root@foo harold]# runlevel
N 5
[root@foo harold]#


You can change the runlevel by running ``init n'' where ``n'' is the 
runlevel that you want.  So, to restart xdm you:

init 3
[wait a minute]
init 5


Let us know if that helps.
