Setup user local

login as pi, password raspberry - password may have changed

Add a user called local, this leaves the pi user as is. This can save reformatting and reinstall when the Pi is to be reused.

add a user called local

sudo adduser local
sudo usermod -a --groups adm,cdrom,sudo,audio,video,plugdev,games,users,netdev,input,spi,gpio,i2c,dialout local

switch user to local, and ensure groups are OK, and network is running

su - local
groups
ifconfig

Note the inet address.

Now it is possible to login (as local) from network.

You may change the hostname by changing the name in /etc/hostname. If you do so, then you should restart before the new hostname works.

Now from another PC on the local network

ping hostname.local

Get a console (terminal window) use SSH From linux:

ssh -X local@hostname.local

Or use putty (can be installed in both Linux and Windows - and probably also Apple).

where "hostname" is replaced with the hostname in /etc/hostname.
