[SSHd] Limiting access from authorized IP's

[Gilles]

Hello

I have a couple of questions about running SSHd:

1. I'd like to limit connections from the Net only from specific IP's.
It seems like there are several ways to do it (/etc/hosts.allow,
AllowHosts/AllowUsers, TCP-wrapper, port-knocking, etc.). Which would
you recommend?

2. Although it's up and running, I can't find SSHd in the list of
installed apps:

$ which sshd

/usr/sbin/sshd

$ pkg_info | grep -i ssh
=> Nada. How come?

Thank you.
