Digitale Infrastruktur

I have access to host herman for LDAP. Recently the shell access was removed and replaced by something that's blocking. This is very annoying because not breakable (CTRL+C is not terminating the ssh session). I understand why I don't have shell access and I'm not asking for. But could this be replaced by a breakable shell-script. for example:

#!/bin/sh

while true
do
date
sleep 60
done

This way I would be able to terminate the ssh in a proper way and avoid ghost sessions / having to kill -9 my ssh client.

Thanks! ;-)
