ssh and running command

[Patrick Hsieh <pahud@ezplay.tv>]

Hello list,

I'd like to execute a certain command upon someone connect to my server
with "ssh robot@my.domain.name". I will not authenticate the visitor in
the ssh session, that is, anyone can do "ssh robot@my.domain.name" in
order to execute my self-defined command or shell script. Is there any
way to configure ssh to achieve this? Additionally, If the
self-defined command or shell script is pertty easy, say, 

#!/bin/sh

export PATH=/bin:/usr/bin && \
echo "Hello there!" && exit 0;


Is there also security problem?
