problems getting remote ssh/X connection working

i'm having trouble getting a remote X connection going with ssh.

I can connect fine to the machine (an HPUX server) with

Code:

$ x -auth -l username remotehost

window manager loads and everything.

but i can't get it to work over a secure connection :( whatever i try and do i get the message about could not connect to display.

the main jist of what i think i want to do is

Code:

$ ssh -X -l username remotehost

but i can't get it to work. init is at runlevel 3, and insecure connections work fine, but i don't know what to try now, and all the documentation i've read doesn't seem to help more than saying to set the -X tag.

Thanks!

check and see if these settings are set in /etc/ssh/sshd_config

Code:

X11Forwarding yes

X11DisplayOffset 10

X11UseLocalhost yes

ssh in again, check the DISPLAY variable, it should be localhost:10.0, launch an X app, if it works then you're tunneling through ssh.

uh oh.....

Code:

$ ssh -l username remotehost

/etc/ssh/ssh_config: line 40: Bad configuration option: X11UseDisplayOffset

/etc/ssh/ssh_config: line 41: Bad configuration option: X11UseLocalhost

/etc/ssh/ssh_config: terminating, 2 bad configuration options

uh oh....mass stupidity.....DisplayOffset, not UseDisplayOffset....oops :P
well, have (kinda) solved things by using

Code:

$ ssh -XAL user hostname

however, i'm running into problems because my use of the system is (primarily) based around starting an environment with the start command. How do i get this to work??? It complains about not recognising window names if i run it in init runlevel 5, and i get the (all too) familiar 'cannot connect to display' message if i go into runlevel 3 first.

Thanks,

I was actually talking about "sshd_config"(note the 'd') which is the config file for the daemon on your ssh server, not the client.
You have to start an X server on the localhost first, then you ssh in to launch you window manager etc.

ah, ok. next newbish question......how do i start X without loading the window manager? i.e. in such a way that "start env_name" will work? many thanks :)
