[LINUX] When you don't know the SCP when you port forward

For security reasons, I wrote a memorandum because the file exchange when port forwarding and communicating via the bastion server always fails.

Execution command

First of all, port forwarding. 1234: 1.2.3.4 is the port used for SSH connection and the IP address of the connection destination, and [email protected] is the user name and IP address of the bastion server to log in to the bastion server. /.Ssh/id_rsa is the private key path.

ssh -A -L 1234:1.2.3.4 -i /.ssh/id_rsa [email protected]

scp connect.

scp -r -i /.ssh/id_rsa -P 10022 user@localhost:/etc/path/to/file /file/ /local/pc/path

This command transfers the contents of the / etc / path / to / file directory on the server to / local / pc / path on the local PC. It is a list of transfer source location.
