Hi!
Yes, it you put this "as is" (eg sshd: ALL: spawn ...) in your hosts.allow you are ALLOWING all ssh connections. (no entry in either hosts.allow or hosts.deny also means allow all)
O.K., but if I had no restrictions, I would not unsecure it more with that, eh? :)
Highly recommend changing the ALL to specific IP addresses/ranges in the hosts.allow file, then use the ALL format in the hosts.deny to deny everything else (in other words allow only those you know/trust, then deny everything else).
"ranges" - how to set up a range?I tried "sshd: 80.81.*.*[...]" and just "sshd: 80.81 [...]" but that doesn't work.
Of course I put "all" in the hosts.deny file... Thanks, Frank
