[ML-General] linux networking questions

[Hunter Fuller]

The long and the short of it is subnet masking. Basically, in home
networking, your subnet mask is almost always 255.255.255.0 also known as a
/24 (slash 24). What this means is that the first three octets of the IPs
of two devices have to be the same before they can talk.

Routers are capable of breaking this boundary, but of course your router
can only know about 192.168.1.0/24 so that won't help you.

If the raspberry pi is handing out addresses in a different range then you
need to put your laptop in that range temporarily, log into the pi, and
reconfigure it to not do that. Unless you intend for it to create its own
separate network that is.
