How did you _disable_ it?

How are they connecting to the server?
RSH/remsh? SSH? Telnet?

From what are they connecting to the server?
An X terminal? Some UNIX workstation? Some
mysterious Windows system? A Macintosh? (I
could go on.)

What, exactly, do you want to do? What does
"x11 forwarding" mean to you?

Or ask the server whence you come.

rux # who -R
root pts/0 Sep 24 20:41 (alp-l.antinode.info)

rux # rem_host=` who -R | sed -e 's/.*($.*$).*/\1/' `

rux # export DISPLAY="${rem_host}:0.0"

rux # echo $DISPLAY
alp-l.antinode.info:0.0

With my weak psychic powers, I'm at such a
disadvantage. I didn't even know that we
were using Telnet from a PC with X software.

What are you talking about?

> saying not able to login.

What, exactly, are you doing? What, exactly,
happens when you do it?

"not able to login" is a long way from "x11
forwarding"

Do you ever answer questions, or do you only
ask more questions, and never with enough
information to make a useful answer possible?
Wait. I think I already know the answer to
that one.

I'll try one more time.

What, exactly, are you doing?

What, exactly, happens when you do it?

when i connect via x-manager through my desktop it throws error as :failed to start the ssh-agent server!! and it asks to check the log messages, so i just tailed the syslogs it shows as Sep 26 13:15:37 Hpux1150 sshd[6387]: Could not reverse map address 192.168.1.103. so i added the 192.168.1.103 in the /etc/hosts , so now also it shows same error as failed to start the ssh-agent server!!

Re: x11 forwarding?

You can't start the xserver on the hp-ux system, correct? Check your /etc/rc.log for both ssh and cde.

Also, is there a ip lookup in x-windows that substitutes the hostname and then, say, writes the hostname in the title window.

You must also uncomment lines in the ssh client on the rx2660 server in the ssh_client file.

ForwardAgent yes
ForwardX11 yes

Re: x11 forwarding?

fizan — Fri, 25 Sep 2009 18:07:09 GMT

in rc.log nothing is found out regarding ssh and cde logins, how to overcome this error?

Re: x11 forwarding?

You must also uncomment lines in the ssh client on the rx2660 server in the ssh_client file.?

in which path the file is located to edit and wat details should be uncommented in that file?

Re: x11 forwarding?

TTr — Fri, 25 Sep 2009 18:25:45 GMT

I mistyped. It is the ssh_config file.

ssh_config: ssh client config file
sshd_config: ssh server config file

Re: x11 forwarding?

fizan — Fri, 25 Sep 2009 19:12:45 GMT

in server side i have edited as u said but in client side how to perform it on the server itself the client file exsists or in the client machine?

Re: x11 forwarding?

TTr — Fri, 25 Sep 2009 19:54:24 GMT

The ssh_config is edited on the rx2600 also. Then you go to your desktop and you try to connect using x11.

Did you check any logs on the desktop? What are you using on the desktop as x-manager? Does it have an ssh client available?
