Just a really quick question, I'm testing the SSH daemon on my desktop at the moment so I'll be able to log in remotely...

There's just minor thing that's bugging me before I let it face the internet, if I telnet onto port 22, it shows straight away what Linux Distro I'm running. Is this output from a text file which I could edit, or could I just switch it off?

Like I say, it's only a minor issue, but generally I think it's best to display as little info as possible

it's nothing to worry about, as the distro is irrelevant and even if you do have and ssh daemon listening, that's not a clue as to a way to hack into your box ...

i have 2 ports open on my box, ssh and vnc - and i'll be damned if i'm gonna 'close' them entirely out of fear of being hacked ...

if you have a non-root (no root user @ all is a good policy) user name, a decent user username and p/w and a good firewall (i only allow my work IP a.t.m.) you should be fine ...

telneting to a ssh port (i haven't seen telnet (be it a daemon) used in a LONG time) is worthless, even if it does give you a "hey, this box is using ubuntu" response ...

Hey, thanks for the quick response. Yeah I've been using a firewall on the box to control what IP ranges can connect, and am using what I regard as a pretty strong user/pass combination. (I'll live to regret saying that....)

Still though I like the idea of not printing any information besides a password prompt...
