SSH Port Forwarding

<<Return to Orgs Help

Mac/Linux/Unix Using Terminal

Overview

You will be logging in to login.utulsa.edu with SSH. Using the SSH command you will be creating a secure port to orgs.utulsa.edu. From there you can use SCP, SFTP, FTP, Fetch, on your machine where you are connecting to orgs.

To get connected complete Step 1 then you may go on to Step 2.

Step 1: Setting Up the Port

1. In a Terminal window type the ssh command:
ssh -l username -L 12345:orgs.utulsa.edu:22 login.utulsa.edu

where:

  • username = your username on login.utulsa.edu
  • 12345 = any number above 1024. This will be the port that orgs.utulsa.edu is pointing to.

2. Enter your campus username and password. Type Yes if you are asked the security acceptance question.

3. Leave the terminal window running. You may minimize it.


Step 2: Connecting to Orgs

The SSH command above set up an open connection to orgs with the hostname called localhost on the port 12345 (using the example above). Leave the terminal window where you ran the above command running; you may minimize it.

Select the tool that you are using.

scp -oPort=12345 * org-username@localhost:/home/org-username/public_html

  • org-username = the username that you login in with on orgs.utulsa.edu
  • 12345 = the port that you set in your ssh command

sftp -oPort=12345 org-username@localhost

where:

  • org-username = the username that you login in with on orgs.utulsa.edu
  • 12345 = the port that you set in your ssh command


--Using SSH in Terminal

ssh -l org-username -oPort=12345 localhost

where:

  • org-username = the username that you login in with on orgs.utulsa.edu
