RaspberryPi/Pi2 SSH 連線設定

RaspberryPi/Pi2 SSH 連線設定

Install an SSH server for remote access:

$ sudo apt-get install openssh-server

修改相關設定

SSH預設port為22，使用預設值容易受攻擊，建議修改

sudo nano /etc/ssh/sshd_config

@# What ports, IPs and protocols we listen for (約第4、5行)
Port 22

將紅字部分修改為自己設定的port

存檔後，重新啟動Pi後完成修改



使用PuTTY連線

相關設定如上

Host Name(192.168.1.123)修改為RaspberryPi的IP

Port(1234)則使用剛剛自己設定的port

Maybe TTL mark is wrong
