Transferring files: FTP, SSH, SCP

FTP

FTF is the oldest protocol. Still used, but deprecated if we speak about security as passwords are not encrypted. Nowadays replaced by:

  • rsyc
  • sftp which is via ssh
  • ncftp
  • yafc
  • ncftp
  • yafc

Secure Shell - SSH

SSH is a cryptographic protocol for secure data transmission.

$ ssh <system_machine>
Logs in to the destination system machine

$ ssh -l <someone> <system_machine>
or
$ ssh <someone@system_machine>
Logs in to the destination system machine with the specified user credentials


SCP

$ scp <localfile> <user@remotesystem>:/home/user/
Copies files between two secure networked hosts via SSH. The transfer is protected by password, which is related to the transfer itself instead of the destination machine.
