extension ssh permission too well done

[EvansPM]

First of all thank you for this great extension!

I use a restricted user created with sudo useradd -s /bin/rbash baye.
with Putty I'm not able to use com commands "ls", but through the extension I can run "ls" which means my restriction is not really complete or your extension managed to bypass it.

I restarted the server, reinstalled the app in case of old connection but it doesn't change anything.

In order to do an investigation I would like to have an idea how you managed to run these commands even in a restricted account.

Edit:
I finally understood that there are two types of restriction: shell restriction and ssh restriction, to restrict it from ssh I used this very good script : https://github.com/RaymiiOrg/boa-diminish-restricted-shell
