Unleash The Awesome Power of SSH

Terms

DNS = Domain Name System
DHCP = Dynamic Host Configuration Protocol
IP = Internet Protocol
LAN = Local Area Network
SFTP = SSH File Transfer Protocol
SSHFS SSH File System
SSH = Secure Shell

Setup Static IP Addresses for Host Machines

Find IP and netmask:

ip a
or
ifconfig

ex. 192.168.0.xxx/24 (24 = 255.255.255.0 netmask)

Find default gateway:

route -n

ex. 192.168.0.1

install SSH Server on Debian/Ubuntu Systems:

sudo apt install openssh-server

Generate SSH Keys:

ssh-keygen -t rsa -b 4096 -C "your name or email."

Copy public key to remote host:

ssh-copy-id user@remote_host

Note: You can copy key pairs directly to new hosts to facilitate sign in to other machines on the network.

Using SFTP:

sftp user@remote_host

ls = list the directory on the remote machine
lls = lists the directory on the local machine
cd = change directory on the remote machine
lcd = change directory on the local machine
get filename1 filename2 = get files from remote machine
get -r directoryname = get a directory from the remote machine
put filename1 filename2 = send files to the remote machine
put -r directoryname = send a directory to the remote machine
bye, exit = leaves SFTP and breaks the connection.

RSYNC over SSH

rsync -av --delete source_directory/ destination_directory.

ex. rsync -av --delete [email protected]:Music/ Music/

Using SSHFS

Install SSHFS on Debian/Ubuntu systems with:

sudo apt install sshfs

create a network share by mounting a directory from the remote host to an empty directory on the local host:

sshfs user@remote_host:directory_path local_directory
