Link redirect server. (Go)

Overview

Switchboard is a link redirect server. It redirects incoming HTTP requests to other URLs. It therefore functions as a personal link shortener.

Examples

With everything set up correctly and the example switchboard.conf:

• http://s/wp redirects to English-language Wikipedia's homepage.
• http://s/wp/Switchboard is equivalent to typing "Switchboard" into English-language Wikipedia's search box.

Requirements

• Go 1.1 or later.
• A local server on which port 80 is available (possibly localhost).
• The ability to add hostnames mapping to this server (via DNS or /etc/hosts).

Installation

Install the binary and configuration file:

• go install github.com/nixprime/switchboard. This builds a bin/switchboard somewhere in your $GOPATH, which you can move to wherever. (The included system startup scripts assume switchboard is located in /usr/local/bin/.)

• Create switchboard.conf somewhere. Use the included switchboard.conf as a guide. (By default, Switchboard assumes that switchboard.conf is located in /etc/.)

  Note that the default configuration instructs the daemon to listen on port 80, the standard HTTP port (so your host should not be running some other HTTP server), and to listen only on the localhost interface (so the Switchboard service will not be accessible from other hosts). Change these settings with the port and listen_on configuration file keys, respectively. Setting listen_on to the empty string ("listen_on": "") will instruct the daemon to accept connections from any network.

Enable the daemon to run as a non-root user:

• If using one of the system startup scripts, or running switchboard as non-root otherwise, allow switchboard to bind ports under 1024:

    sudo apt-get install libcap2-bin
    sudo setcap cap_net_bind_service+ep /usr/local/bin/switchboard
  

Enable automatic start at boot:

• If your system uses Upstart (e.g., Ubuntu prior to 15.04), and you want to use the included Upstart script to start Switchboard automatically, put upstart/switchboard.conf in /etc/init/. The daemon will now start on the next boot. To start it manually, run service switchboard start as root.

• If your system uses systemd (e.g., Arch Linux or Fedora, or Ubuntu 15.04 or later), and you want to use the included systemd script to start Switchboard automatically, put systemd/switchboard.service in /usr/lib/systemd/system. To enable the service on boot, run systemctl enable switchboard as root. To start the service manually, run systemctl start switchboard as root.

Configure hostname resolution:

• Configure either your host's local hostname resolution (e.g., the /etc/hosts file) or your local DNS zone, if applicable, to point whatever hostname(s) you want Switchboard to use to the IP address of the machine running Switchboard. How to configure DNS is beyond the scope of this document. A simple set of entries in /etc/hosts might be:

    127.0.0.1  s  # map `s` hostname to Switchboard on localhost
    127.0.0.1  m  # map `m` hostname to Switchboard on localhost
