Scp,sftp through a tunnel

Learn how to copy files through a tunnel using scp or sftp

Prerequisites

Copying files to a remote system over scp or sftp requires an SSH server running on the remote side. On almost all Linux systems SSH is installed and active.
Create a tunnel for SSH access to the remote server. The tunnel will end on a random port on your rport server. Remember the port number.
Get the port number of the tunnel

Using scp or rsync

To copy a file to the remote system over the tunnel via scp use
scp -P <PORT> <LOCAL-FILE> <USER>@<RPORT-SERVER>:<DESTINATION>
For example:
scp -P 22708 /etc/hosts [email protected]:/tmp/
Doing the same over rsync
rsync -e "ssh -p 22708" /etc/hosts [email protected]:/tmp/

Using Filezilla

  • Open the site manager of Filezilla.
  • Create a new site using the "SFTP- SSH File Transfer Protocol.
  • Enter the name of the rport server as "Host".
  • Enter the port of the tunnel as port for the Filezilla connection
Use Filezilla for file transfers over a tunnel
