I have a mercurial repository on a secure server, to which I want to grant secure access to an external user.

I added for him a user account and publickey ssh authentication so that now he could push/pull changesets via ssh.

My question is: how can I make this new user account completely disabled from doing anything or accessing any data on the server other than accessing the repository? E.g. he shouldn't even have the possibility to enter an interactive shell session.

Thanks
