OpenSSH - X Connection broken

Paul Torgerson — Mon, 06 May 2002 19:54:24 GMT

I have installed/configured v3.1p1 on all our hosts (11.0/11.11)

I am using forwarding X11. All works fine for my 'normal' user. X-apps execute properly. However, when I 'su' to root, I receive the following:

X connection to localhost:10.0 broken (explicit kill or server shutdown)

Dug around the docs/forums/OpenSSH site but not finding an 'obvious' answer.

Any help would be fantastic!

Thank you.

Paul

Forgot to mention that my display variable is the same after I su as before.

Do not have this problem w/ normal remsh/rlogin.

Well, I kept looking around and found that I was not setting XAUTHORITY in my .profile. Once I set that to $HOME/.Xauthority, my X-apps ran find when I was 'su'd to root.

Sounds like I need to learn a few things...

I just upgraded to from 3.0.2 to 3.1p1 on HPUX 11.00... sam and the sw utilities work fine, but anything else, specifically Legato Networker Admin (nwadmin) and the Ignite utilities are bombing with this error:

X connection to localhost:10.0 broken (explicit kill or server shutdown).

I've ensure that DISPLAY and XAUTHORITY are correct and exported.

Any other ideas?

Set 'X11UseLocalhost no' in sshd_config.

Thanks Paul. A new parameter I didn't know about; It wasn't in the config file which was preserved from 3.0.2. Is this new in 3.1?

I found that bit-O-info on:
http://www.openssh.org/faq.html

"3.12 - I upgraded to OpenSSH 3.1 and X11 forwarding stopped working.
Starting with OpenSSH 3.1, the sshd x11 forwarding server listens on localhost by default; see the sshd X11UseLocalhost option to revert to prior behaviour if your older X11 clients do not function with this configuration.
In general, X11 clients using X11 R6 should work with the default setting. Some vendors, including HP, ship X11 clients with R6 and R5 libs, so some clients will work, and others will not work. This is true for HP-UX 11.X.
