Recently I've started hitting this problem on Ubuntu 8.04.
If I attempt to login to a client with a bad password, the LDM login screen
displays the message "Verifying password, please wait..." as normal, but
then never returns to the login. The password field is still there and I
can type in it, but it doesn't seem to have an effect. Eventually the
screen goes black with blinking underline cursor in the top left corner.
From the client at this point the only option appears to be Ctrl-Alt-Del
to reboot the machine.
If I open a terminal session on the client I can see this process hanging
around:
/usr/bin/ssh -X -t -M -S /var/run/ldm_socket_vt7_{server_ip} \
[EMAIL PROTECTED] echo LTSPROCKS ; LANG=C /bin/sh -
There are no corresponding sshd processes on the server.
Killing that process then restores the LDM login screen.
The ldm.log on the client contains this:
-begin-
LDM2 starting
LDM2 running on ip address {client_ip}
Launching Xorg
Spawning greeter: /usr/lib/ldm/ldmgtkgreet
In get_userid
In get_passwd
In get_host
In get_language
In get_session
Establishing a session with {server_ip}
Attempting ssh session as user
In set_message
ssh_chat: looking for ssword: from ssh

Established ssh session.

Executing rc files.

X session ended.
Executing rc files.

Ending ssh session.

-end-
That looks like expect is misinterpreting the response from the ssh daemon.
But why would the ssh client process just hang around like that after
failing to connect?
