SSH: Makes you the owner of a SSH enabled system through network
:~/ ssh username@ipaddress -v (and then give the password)
-v option gives you a verbose output which helps us to understand the background
For passwordless login you can generate a public key and install it in the host system.
:~/ ssh-keygen -t rsa -f filename
this generates a filename.pub in ~/.ssh directory. Then you need to copy the content of the file filename.pub into the host file .ssh/authorized_keys
SCP: This tool allows you to copy files over ssh
for a single file
:~/ scp sourcefile destination
or for a directory
:~/ scp -r sourcedirectory destination
RSync: A fabulous tool to sync files between directories using ssh. Huge amount of options are there to enable or disable certain feature. Most used feature would be just updating on local or remote directory to another one.
for local directories
:~/ rsync -auv sourcedirectory destinationdirectory
or else you can do between a remote location
:~/ rsync -auv user@ip:relativepath/sourcedirectory destinationdirectory
The above one's don't delete destination files which are not in the source.
Once we got max speed @ 12 MB/s in our 100 Mbps network while backing up a computer. Most of us were astonished as the content was multiple files. Have to research about rsync.
SSHFS: This tool enables us to mount the host system directory into our filesystem
:~/ sshfs user@ip:relativepath/sourcedirectory destinationdirectory
This enables us to treat the remote directory as a part of our system. Share your thoughts and also post info on some other ssh tools.
