Mac: VPN over SSH using sshuttle

Image
Summary:
Sometimes it's simply easier to run or do things from your local system rather than rely on a bastion/jumphost.  sshuttle allows you to utilize a Linux bastion/jumphost as a psuedo VPN endpoint.

Full documentation and source can be found here:

Walkthrough:
Brew is probably the easiest installation method and less prone to complications by using pip.  So that's what I'll go through here:

Launch Terminalbrew install sshuttlesshuttle -r usernameonLinuxSSHhost@LinuxSSHhostnameorIP 192.168.50.0/24 Done.  Easy right?  Now upon successful connection, all traffic bound for an ip on 192.168.50.0/24 will tunnel through your Linux SSH host.

Set an alias to launch powershell in terminalUpdate powershell on launch.Solution: Easiest way to go about this is simply to insert some alias into my .bash_profile.  Like so: Launch Terminalnano ~/.bash_profileor vi if that suits your fancy.alias powershellupdate="brew update; brew cask reinstall powershell; pwsh"alias powershell="pwsh"Exit [Ctrl+X] and Y to save.source .bash_profileThis is to refresh your current bash session w/ your newly edited profile. Once done, I can now type either "powershellupdate" or "powershell" in terminal.  I did this approach for simplicity so I can quickly launch powershell if I don't need it to…
