NB: Forwarding all traffic system wide requires root privileges, so you will need sudo rights, or execute this as root. It is also possible to limit the VPN to specific IPs or subnets. With the subnet 0.0.0.0/0 you will set up a global system wide VPN. Then, just set up your SSH based VPN: sshuttle -r 0.0.0.0/0 Network Options Within the Network Settings dialog, select the Manual proxy configuration radio button and enter the following for the SOCKS Host: and Port: SOCKS Host: localhost. Within the Advanced tab, click on the Network tab and click the Settings button. Installation is easy, using brew install sshuttle for MacOS, or sudo apt install sshuttle for Debian or Ubuntu systems. Now, launch Firefox, select Tools->Options and click the Advanced tab. A few python scripts around SSH to do exactly what I wanted. This looked like the perfect tool for the job. Some googling showed me a easier way: sshuttle But I am not an iptables wizard and I did not have the time for this. Under the Network tab, below Connection click on Settings. It is not impossible to solve this issue with some custom routes using a few iptables rules. In Firefox go to Options and click Advanced on the left side. The disadvantages of this approach is: you will have to configure every app to use the proxy. You only need the tunnel after all.Īny application with SOCKS5 support will be able to use this tunnel. -N means: do not open a shell or execute a command on the remote host.-q: "quiet mode" to suppress unneeded output.All traffic to that port will be forwarded using the SOCKS5 protocol to the remote host You don't need any special rights, and no other applications besides SSH: ssh -D8080 -q -N breakdown of the options: It is trivial to setup a SOCKS5 proxy to any server you can reach using SSH. But there are much easier solutions using SSH. An obvious solution would be to setup my own VPN using OpenVPN or Wireguard and connect to that. So when I am not at home, I cannot connect to them. ssh -C2TNv -D8080 The actual host and port to connect to is specified by the browser as part of each SOCKS request. For example, some of the client servers have whitelisting, allowing only my home ip. ssh -D9090 -N usermysshserver Then firefox has to be configured to use the ssh tunnel: open Preferences open Network Settings (scroll down in General tab) choose Manual proxy configuration in the SOCKS Host field, write localhost and in the Port field, write 9090 keep the SOCKS v5 button selected click OK Done. You need a running sshd at the remote end, and you need to ssh to it, not the web server. I use ProtonVPN for that, they have servers in most countries.īut sometimes you want to mask your IP with a specific other IP. For example I need it to be able to watch Dutch television programs when I am abroad. ![]() I would still recommend that people run their own private mirror if they are running their own private cluster but this is useful in a pinch.A VPN is useful to mask your external IP address. I’ve found this useful for managing some systems on our campus that are on a private LAN but are routed to campus only, so they can’t reach ‘the world’ but my computer can. From this area, add in a source port (I’ve chosen 9870 but this can be any unused port), and choose ‘Dynamic’. If you are curious if it is actually doing anything, add a -v to your ssh connection and it’ll send debugging information to your terminal, and you’ll see each proxied connection from yum/dnf.įor ansible to use it, you’d set ‘ssh_connection’ in your ansible.ini to have the extra -R option, and then deploy a yum/dnf config that uses the proxy. From Putty, go down to Connection > SSH > Tunnels. Yum –setopt=’proxy=socks5://localhost:8000′ update ‘RemoteForward 8000’ or ‘ssh -R 8000 hostname’ with the command line, and on the remote side, set ‘proxy=socks5://localhost:8000’ in the yum.conf or dnf.conf, or set it on the command line with: From Firefoxs Tools menu, choose Options, and from the Advanced section choose the Network tab. I am able to connect to my hosts that way without any problems. Also note that I don't have anything in the No Proxy for: box. Then I make sure that SOCKS v5 is selected. ![]() (I’m just using port 8000 as an example here, it can be any unused port above 1024 for regular users.)įor the second, it’s largely the same thing, except you’d use Once your proxys up and running, configure Firefox to use it. ssh -CfND 1234 usernameproxyhost Then in Firefox under the Connection Settings in the Manual proxy configuration I only fill in the SOCKS Host: with 127.0.0.1 and Port: 1234. Then just set your SOCKS5 proxy settings in Firefox to localhost:8000. What part? For the first part, either define ‘DynamicForward 8000’ in a Host section in ~/.ssh/config, or run ‘ssh -D 8000 hostname’ to set it with command line options.
