I think I'm needing a little help getting started in networking. I know having computers work together is what Linux is designed for. It shouldn't be hard at all. I've found a lot of very comprehensible information out there to help people like me. There's just one thing. It's not really giving me the picture I need to understand what is going on inside this machine o' mine. And therefor I can't get it to work
One new lappy with ethernet cable
One old lappy gone wireless
One cable modem
One wired/wireless router
One network capable external drive (wired ethernet connection)
To hook them up, so I can ssh from one machine in the other and vice versa. I also want to be able to access my external drive through the router. And do this securely, so that no one else can access my files.
Now, I can ping my router from both machines. I can access Internet from both machines. But I can't see one machine from the other. I've got the ssh deamons running, I've build authentication keys and copied them to both machines. Ehm. But I can't even seem to ping one machine from the other.
Reading up on these things, I felt I wandered into a maze. I lost track of where I'd already been, switched strategies (ssh, shared folders, ftp) and to top it all, I broke internet access on both machines. Of course I didn't let this compromise my main install, but my test installs are broken atm. One of the mistakes I made was to skip steps that later on seemed necessary. For example, I can't seem to log in to my router.
This let me to the following idea. I'll make a fresh default install of 5.9 on both machines. I'll add or enable the necessary services and applications.
Now I'll probably am overlooking very obvious information or sources. But if someone can put me on the right track, I'll be very grateful
