ssh

https://www.raspberrypi.org/documentation/remote-access/ssh/

概念：把PC與Raspberry掛在同區網底下，使用nmap掃出樹莓的IP，再使用ssh登入。

handy@handy-dell ~ $ ifconfig

得知自已ip為 192.168.43.19，接著使用nmap掃同網段機器

handy@handy-dell ~ $ nmap 192.168.43.*

掃出來的結果，得知樹莓IP為192.168.43.58，接著就直接對IP連了

handy@handy-dell ~ $ ssh [email protected]

pi@raspberrypi:~ $

登入成功後，提示字變成 pi@raspberrypi，這樣就已經在樹莓底下了。

要離開的話，則下exit即可。

pi@raspberrypi:~/solarpidistro/main/data $ exit
logout
Connection to 192.168.43.58 closed.
handy@handy-dell ~ $

提示字又變回 handy@handy-dell了
