Title: Ssh Xforwarding Problems With Hentges Rom
Post by: darmou on January 02, 2007, 07:35:32 am

I'm having problems with getting openssh with the latest snapshot of the hentges.rom to work with x forwading.  


I use ssh -Y collie to get to my zaurus.

Here is my sshd_config file:



#       $OpenBSD: sshd_config,v 1.59 2002/09/25 11:17:16 markus Exp $

# This is the sshd server system-wide configuration file.  See
# sshd_config(5) for more information.

# This sshd was compiled with PATH=/usr/bin:/bin:/usr/sbin:/sbin

# The strategy used for options in the default sshd_config shipped with
# OpenSSH is to specify options with their default value where
# possible, but leave them commented.  Uncommented options change a
# default value.

ssh -Y?

try ssh -X <host> <app>

sorry read the manual

another trick if you have the time to set up the "trusted" stuff or disable it is to change the DISPLAY enviremont varible by hand, you lose fowrding over ssh but that means a speedup (the Z aint that fast)

basically you need to get the "magic cookie" which ssh has a clever hack for to the Z if you dont want to disable security

ssh -Y?

yes that works fine with openzaurus on a 3100 with dropbear.

Hentges uses openssh

I tried your method no dice
tenchi:~ darmou$ ssh -X collie /usr/bin/gpe-calculator    
darmou@collie's password:

(gpe-calculator:3341): Gtk-WARNING **: cannot open display:

darmou

I thought it may be something to do with the sshd_config file because, when I echo display after using -Y

I get:

tenchi:~ darmou$ ssh -Y -l root collie
root@collie's password:
Warning: No xauth data; using fake authentication data for X11 forwarding.
Last login: Tue Jan  2 23:37:57 2007 from 10.1.1.34
root@collie:~# echo $DISPLAY

root@collie:~#

with the 3100  I get
localhost:10.0

which is correct:

DOH!  I just answered my own question, removed openssh-sshd and reinstalled dropbear.

restarted and dada, xforwarding works.
