Ubuntu – How to set a global SOCKS proxy in Xubuntu

"Proxifier" for Windows seems like an anonymous proxy/VPN-type-thing.

On Ubuntu then, you want Tor.

Get the Tor Bundle at https://www.torproject.org/download/download

You may want to check your DNS setup.

I also use multiple subdomains which I create on the fly for various applications using web frameworks such as Python Django or Ruby on Rails.

A typical example is at mydomain.com I may want to have myapp.mydomain.com where myapp is a framework served at my_server_IP:some_port.

In order to achieve such thing (many subdomains on the fly at the same OR different ports) I delegate the decision from the DNS to the Web server with a Wildcard DNS record see Wikipedia. As the name suggests, such record produces a catch all domain which can be easily managed from the web server with the use of virtual hosts - domain proxys, etc.

An A wildcard record at GoDaddy's DNS management tool looks like this:

Host Points To TTL

* YOUR_SERVER_IP 1 Hour

And an Nginx configuration file which passes all requests for app.mydomain.com to otherserver.com:9000/index.html

The result: you type in browser http://app.mydomain.com and Nginx serves content from otherserver.com:9000/index.html which can be another server or application, etc

server {
    listen   80;

    server_name app.mydomain.com www.app.mydomain.com;

    access_log  /var/log/nginx/app_mydomain_com_access.log;
    error_log   /var/log/nginx/pp_mydomain_com_error.log;

    error_page 404 /404.html;

    error_page 500 502 503 504 /50x.html;

    location / {
        proxy_pass http://otherserver.com:9000/index.html;
    }

}
