Hi All
Does anyone know any reasons why I could not get a shell prompt after
logon via ssh?
I am running kernel 2.6.9 supplied by LTSP.org and OpenSSH-3.7p1 daemon
this is the log that I get on the client:

and then nothing and terminal window appears to be hung, Ctrl-C and
Ctrl-D do not work.
this is the log from the sshd itself, any help to resolve this problen
would be appreciated:
