A user-friendly PHP Looking Glass

branch: master



LookingGlass is a user-friendly PHP based looking glass that allows the public (via a web interface) to execute network commands on behalf of your server.



The demo is hosted on a 50MB (RAM) VPS. 502 errors may occur in events of high use.


  • Automated install via bash script
  • IPv4 & IPv6 support
  • Live output via long polling
  • Multiple themes
  • Rate limiting of network commands

Implemented commands

  • host
  • mtr
  • mtr6 (IPv6)
  • ping
  • ping6 (IPv6)
  • traceroute
  • traceroute6 (IPv6)

IPv6 commands will only work if your server has external IPv6 setup (or tunneled)


  • PHP >= 5.3
  • SSH/Terminal access (able to install commands/functions if non-existent)


  1. Download LookingGlass to the intended folder within your web directory (and unzip)
  2. Navigate to the LookingGlass subdirectory in terminal
  3. Run bash
  4. Follow the instructions and will take care of the rest

Forgot a setting? Simply run the script again


To enable output buffering on Nginx, please append the following to your PHP configuration:

location ~ \.php$ {

    # Append the following
    fastcgi_buffer_size   1k;
    fastcgi_buffers       128 1k;
    fastcgi_max_temp_file_size 0;
    gzip off;

I recommend that you create a separate host file for LookingGlass OR a directory specific PHP "location". This is due to these settings not being optimal for conventional use.
