Set up SSH Server

---

It can be convenient if your laptop can be a ssh server, so anyone on the same network (LAN) can ssh into it.

sudo apt update
sudo apt install openssh-server
sudo systemctl status ssh #should be running
sudo ufw allow # allow firewall configuration tool called ufw
ssh yui@192.168.1.100 # Then password
    

Check ip-address

ifconfig
    

Check username

whoami
    

Notes

1. If there are additional firewall softwares installed, it is better to turn those off, for exmaple McAfee.
