The goal is to enable Firefox (on Ubuntu 16.04) to remotely ssh-tunnel and administer the home router. The command:

ssh -D localhost:3000 user@myfqdn.asuscomm.com

connects a BASH terminal to the SSH server (on the router).

Firefox network settings was configured per instructions:

Attempts to tunnel traffic through browser (http://www.whatismyip.com) return "unable to connect" and BASH returns multiple instances:

channel 3: open failed: administratively prohibited:

What is the root cause of the message above and what is the corrective action?

Router (SSH Server) Configuration:

  • SSH hosted Asus router with Optware installed
  • unable to locate sshd_config find . | grep -i sshd_config
  • Instead of find . | grep ..., which searches for your current (arbitrary) directory, use find / .... – Jeff Schaller Aug 14 at 19:10
  • @JeffSchaller Thank you for commenting. Before executing the find commend, the command cd / was executed. If you can provide the exact command, I can can try it and post the results for you – gatorback Aug 14 at 19:18
  • To clarify, are you trying to admin the router (which allows admin only on the local side) from an external network? Or are you trying to proxy all your firefox traffic through a tunnel? – user1794469 Aug 14 at 19:18
  • @gatorback, I'd suggest find / -name sshd_config – Jeff Schaller Aug 14 at 19:20
  • @user1794469 In the future I would like to admin the remote router from the browser tunnel remotely, however, I am testing the tunnel with the URL www.whatismyip.com, which fails to return a results when the Firefox proxy is engaged. – gatorback Aug 14 at 19:20
