Mac os x create ssh tunnel

To terminate the tunnel we need to identify the process ID PID using the ps command, and then kill it using the kill command. Find the line that looks like the command you entered earlier to create the tunnel. Here's some sample output:. From the beginning of the line, in one of the first two columns, is a digit number.

This is the PID.

Above, the sample PID of is highlighted. Now that you know what the PID is, you can use the kill command to bring the tunnel down. Use your own PID when you kill the process. In Windows there isn't an easy way to automate the connection process, but both PuTTY and Firefox can save the settings you've previously entered, so just open the connections again to use the tunnel again. For OS X or Linux systems, we can make an alias or create a script to quickly create the tunnel for us. The following are two ways to automate the tunnel process. If you want an icon to double click and the tunnel just starts, we can create a simple BASH script to do the job.

You can always use the which firefox command to find out where it is on your system. In the script below replace the path to Firefox with the one that is appropriate for your system. Save your script. Make the script executable, so that when you double click on it, it will execute. From the command line, enter this command to add execute permissions, using your own script path:.

The script will open a terminal window, start the SSH connection, and launch Firefox. Feel free to close the terminal window. As long as you kept the proxy settings in Firefox, you can start browsing over your secure connection.

If you find yourself on the command line frequently and want to bring up the tunnel, you can create a BASH alias to do the job for you. Different Linux distributions and OS X releases save aliases in different places. The best bet is to look for one of the following files and search for alias to see where other aliases are currently being saved. Possibilities include. Once you've located the correct file, add this alias below any you already have, or just at the end of the file.

Your aliases are only loaded when you start a new shell, so close your terminal session and start a new one. This alias sets up your tunnel, then launches Firefox for you and returns you to the command prompt. However, if you've discovered that you can't make an SSH connection out due to a restrictive firewall, then it's likely that port 22, which is required to create the tunnel, is being blocked. If you can control the proxy server's SSH settings with superuser access to a DigitalOcean Droplet, you will be able to do this , you can set SSH to listen on a port other than Aside from the questionable plan of running port scans with a tool like ShieldsUP!

Ports that are often open include 80 general web traffic and SSL web traffic.

If your SSH server isn't serving web content, we can tell SSH to use one of these web ports to communicate over instead of the default port Or, use the built in console from the control panel, but you may not want to do this if you're afraid your web traffic is being watched. We can either replace 22 entirely which is a good SSH hardening technique anyway , or add a second port for SSH to listen on.

We'll choose to have SSH listen on multiple ports, so we'll add a new line under Port 22 that reads Port Here is an example:. Depending on your distribution, the name of the SSH server daemon may be different, but it's likely to be ssh or sshd. If one doesn't work try the other.

To verify that your new SSH port works, open a new shell don't close the current one yet, just in case you accidentally locked yourself out and SSH in using the new port. If you are successful, you can now log out of both shells and open your SSH tunnel using the new port.

That's it! The Firefox settings will be exactly the same since they don't depend on the SSH port, just the tunnel port above. Subscribe Subscribed. We hope you find this tutorial helpful.

If you receive this warning again for the same Linode after the key has already been cached, you should not trust the connection and investigate matters further.
