Connecting to Metworx via SSH and uploading/downloading files from workflow via ssh protocols
This document walks through connecting to Metworx workflow via ssh, and several common scenarios to upload files to/from Metworx workflows.
It is assumed that the user have previously generated public/private key pair to be used for authentication. Generating the key ssh key pairs is described here
For security reasons, authentication via ssh protocols is restricted to private/public keys, and password authentication is not allowed.
To authenticate, the user must provide a private key for authentication, and contents of a corresponding ssh public key must be on the Metworx workflow, in the users home directory
To determine the username and hostname of workflow to connect to, click on the workflow name on Metworx Dashboard
and make a note of Username and Hostname
. Again, you must have a private key that goes with the public key that is already on the Workflow in the
On windows, a program called Putty can be used. It is assumed that Putty application is already installed on the Windows workstation and these are the steps to connect
- Open Putty application. It will take you to the new session screen.
- For hostname, paste or type in hostname noted in a previous step
- Under Auth section of configuration, specify the full path to the private ssh key file
- Click on "Open" to connect. When connecting to a host for a first time, you maybe alerted to accept the new servers host key -- just accept the warning.
- When asked, specify the username.
To ssh from a linux server to Metworx workflow, ssh command can be used Where: username: sergeyn hostname: i-00ade5c2f23f4102c.metworx.com
% ssh -l sergeyn i-00ade5c2f23f4102c.metworx.com The authenticity of host 'i-00ade5c2f23f4102c.metworx.com (220.127.116.11)' can't be established. ECDSA key fingerprint is SHA256:6q6GLcSjPexrrOgyrncfMMCDrVKxXhre0qSCm9KofdM. Are you sure you want to continue connecting (yes/no/[fingerprint])? yes Warning: Permanently added 'i-00ade5c2f23f4102c.metworx.com,18.104.22.168' (ECDSA) to the list of known hosts.
Please note, it is assumed that the private ssh key file is in default location of ~/.ssh/id_rsa (the file was created in a previous step)
On windows, you can use WinSCP application to copy files between your workstation to your workflow.
- Open the WinSCP and and fill in hostname and username (leave password blank) . Leave other fields as default (i.e. SCP protocol)
- Click on Advanced, and, in a screen that comes up, click on Authentication. Specify a full path to the private key file, and click OK.
- Click Log in.
- If a warning comes up about new host, accept it. You should now get a screen on which you can copy files between local and remote by dragging them right-clicking on the files.
ON linux, scp command is commonly used to upload and download files.
file.txt from a local current directory to /tmp on the Metworx workflow, you would run the following command on the local server:
% scp file.txt firstname.lastname@example.org:/tmp file.txt 100% 1690 205.2KB/s 00:00
To copy entire
/data/proj1 directory on the Metworx workflow to the current directory on the local unix server, you would run the following on the linux server
scp -pr email@example.com:/data/proj1 .
-pr options specifies to copy directory recursively AND preserves the timestamps on all files.
