Re: how can I set $REMOTEHOST ( so I can set $DISPLAY with sshd w\X11 forwarding)

I'm not 100 % sure what you are saying.
Are you trying to say that the cygwin sshd does not respect the -X and -Y flags
passed to the local ssh process?
And that for the above named reason you are forced to manually set the DISPLAY variable?

hi -

trying to figure out how to set $REMOTEHOST when I ssh into a machine running
cygwin's imp. of sshd.  X11 forwarding works great when I set the $DISPLAY
properly, but I'd like to have it done in the .bashrc file (by checking if the
$REMOTEHOST var is set).

I've tried looking through the startup scripts on both my cygwin install and a
rh9 box, but can't find where it gets set.  can anyone point me in the right
direction?










yeah.  pretty much.  I've set the "ForwardX11 yes" in the sshd_config file on
the server I log into and I've also set it in the ssh_config with the client I'm
using to log into it.


and you sent the sshd a SIGHUP to re-read the config file after making the changes, right?



piano{pwaltman}51: ssh -X grad107m pwaltman@grad107m's password: Last login: Fri Aug 6 19:16:42 2004 from lin04.eecs.tufts.edu

  pwaltman@GRAD107M ~
  $ echo $DISPLAY
  127.0.0.1:0

even when I use the -X flag, it still set's my $DISPLAY to the above value and
when I start an X11 app, like xterm, it ends up getting launched in the server's
x-server and appears on the desktop of the server (grad107m).  If I set the
$DISPLAY to localhost:10.0, everything works fine and it appears on the client.

not sure why, ergo the reason I want to use the $REMOTEHOST var as a means to
check if I've ssh'd in remotely and then use something like

if $?REMOTEHOST
  export DISPLAY=$REMOTEHOST:0.0

thanks for any ideas,

Peter

p.s. forgive the shell script syntax errors. I don't remember the exact script,
but I've seen folks who've done it this way.
