Hi,

unless I did not get you wrong:

In case I am somewhat sure that the application is well programmed
and doesn't open any security holes I sometimes use the application
as a shell itself. Ending the application will end the ssh session:

# cat /etc/passwd
[...]
frankfancy:x:1234:1234:Frank Fancy:/home/dummy:/usr/bin/cmatrix
doro_debug:x:1235:1235:Doro
Debugger:/home/debug:/home/debug/bin/debugconsole

Do not forget to allow your application as a valid shell:
# cat /etc/shells
# /etc/shells: valid login shells
/bin/csh
/bin/sh
/usr/bin/es
/usr/bin/ksh
/bin/ksh
/usr/bin/rc
/usr/bin/tcsh
/bin/tcsh
/usr/bin/esh
/bin/bash
/bin/rbash
/usr/bin/cmatrix

Cmatrix makes a fancy indicator that my ssh portforwarding is still
alive while not allowing me to fiddle around with the session for
something else and close it accidentially.

Hope it helps,
Norbert
