Re: [LUG] Laptop problem


Hmm, I garbled that a little bit so I better clarify... well done me.

The above steps are for setting up SSHD and finding the IP address to
connect to on *any* of your systems - do this on any computer that you
want to listen on SSH (that's all of them by the way). Do this first on
your working laptop for testing and then the faulty laptop for fault
finding. I'd definitely enable it on your Desktop as well while you're
at it.

These are the steps (well, step singular really) for connecting to any
listening system - you can already run this from any Linux machine you
have as every distro ships a SSH client by default.

Confusing myself here - for your test you'll be connecting FROM your
Desktop TO the laptop so it's the potential firewall on the laptop you
need to be aware might filter or block TCP:22, not the Desktop.

That should make more sense now.
