Download [LookingGlass](https://github.com/telephone/LookingGlass/archive/v1.3.0.tar.gz) to the intended 41 | folder within your web directory 42 | 2. Extract archive: 43 | - Option #1 - Extract archive to the current directory: 44 | - `tar -zxvf LookingGlass-1.3.0.tar.gz --strip-components 1` 45 | - Option #2 - Extract archive to a directory named `LookingGlass`: 46 | - `tar -zxvf LookingGlass-1.3.0.tar.gz --transform 's!^[^/]\+\($\|/\)!LookingGlass\1!'` 47 | 3. Navigate to the `LookingGlass` subdirectory in terminal 48 | 4. Run `bash configure.sh` 49 | 5. Follow the instructions and `configure.sh` will take care of the rest 50 | 51 | _Forgot a setting? Simply run the `configure.sh` script again_ 52 | 53 | ## Updating 54 | 55 | 1. Download [LookingGlass](https://github.com/telephone/LookingGlass/archive/v1.3.0.tar.gz) to the folder containing 56 | your existing install 57 | 2. Extract archive: `tar -zxvf LookingGlass-1.3.0.tar.gz --overwrite --strip-components 1` 58 | - This will overwrite/update existing files 59 | 3. Navigate to the `LookingGlass` subdirectory in terminal 60 | 4. Run `bash configure.sh` 61 | 5. Follow the instructions and `configure.sh` will take care of the rest 62 | - Note: Re-enter test files to create random test files from `GNU shred` 63 | 64 | _Forgot a setting? Simply run the `configure.sh` script again_ 65 | 66 | ## Apache 67 | 68 | An .htaccess is included which protects the rate-limit database, disables indexes, and disables gzip on test files. 69 | Ensure `AllowOverride` is on for .htaccess to take effect. 70 | 71 | Output buffering __should__ work by default. 72 | 73 | For an HTTPS setup, please visit: 74 | - [Mozilla SSL Configuration Generator](https://mozilla.github.io/server-side-tls/ssl-config-generator/) 75 | 76 | ## Nginx 77 | 78 | To enable output buffering, and disable gzip on test files please refer to the provided configuration: 79 | 80 | [HTTP setup](LookingGlass/lookingglass-http.nginx.conf) 81 | 82 | The provided config is setup for LookingGlass to be on a subdomain/domain root. 83 | 84 | For an HTTPS setup please visit: 85 | - [Best nginx configuration for security](http://tautt.com/best-nginx-configuration-for-security/) 86 | - [Mozilla SSL Configuration Generator](https://mozilla.github.io/server-side-tls/ssl-config-generator/) 87 | 88 | ## License 89 | 90 | Code is licensed under MIT Public License. 91 | 92 | * If you wish to support my efforts, keep the "Powered by LookingGlass" link intact. 93 | -------------------------------------------------------------------------------- /ajax.php: -------------------------------------------------------------------------------- 1 | 7 | * @copyright 2015 Nick Adams. 8 | * @link http://iamtelephone.com 9 | * @license http://opensource.org/licenses/MIT MIT License 10 | * @version 1.3.0 11 | */ 12 | 13 | /** 14 | * NOTE: 15 | * Version 1 will continue to allow direct access to ajax.php (no CSRF protection). 16 | * I recommend setting a reasonable rate-limit to overcome abuse 17 | */ 18 | 19 | // check whether command and host are set 20 | if (isset($_GET['cmd']) && isset($_GET['host'])) { 21 | // define available commands 22 | $cmds = array('host', 'mtr', 'mtr6', 'ping', 'ping6', 'traceroute', 'traceroute6'); 23 | // verify command 24 | if (in_array($_GET['cmd'], $cmds)) { 25 | // include required scripts 26 | $required = array('LookingGlass.php', 'RateLimit.php', 'Config.php'); 27 | foreach ($required as $val) { 28 | require 'LookingGlass/' . $val; 29 | } 30 | 31 | // lazy check 32 | if (!isset($rateLimit)) { 33 | $rateLimit = 0; 34 | } 35 | 36 | // instantiate LookingGlass & RateLimit 37 | $lg = new Telephone\LookingGlass(); 38 | $limit = new Telephone\LookingGlass\RateLimit($rateLimit); 39 | 40 | // check IP against database 41 | $limit->rateLimit($rateLimit); 42 | 43 | // execute command 44 | $output = $lg->$_GET['cmd']($_GET['host']); 45 | if ($output) { 46 | exit(); 47 | } 48 | } 49 | } 50 | // report error 51 | exit('Unauthorized request'); -------------------------------------------------------------------------------- /assets/js/LookingGlass.js: -------------------------------------------------------------------------------- 1 | /** 2 | * LookingGlass jQuery file 3 | */ 4 | $(document).ready(function() { 5 | // onclick, set user IP to input value 6 | $('#userip').click(function () { 7 | $('#host').val($('#userip').text()); 8 | }); 9 | // form submit 10 | $('#networktest').submit(function() { 11 | // define vars 12 | var host = $('input[name=host]').val(); 13 | var data = 'cmd=' + $('select[name=cmd]').val() + '&host=' + host; 14 | // quick validation 15 | if (host == '') { 16 | $('#hosterror').addClass('error'); 17 | } 18 | // submit form 19 | else { 20 | // disable submit button + blank response 21 | $('#submit').attr('disabled', 'true').text('Loading...'); 22 | $('#response').html(); 23 | 24 | // call async request 25 | var xhr = new XMLHttpRequest(); 26 | xhr.open('GET', 'ajax.php?' + data, true); 27 | xhr.send(null); 28 | var timer; 29 | timer = window.setInterval(function() { 30 | // on completion 31 | if (xhr.readyState == XMLHttpRequest.DONE) { 32 | window.clearTimeout(timer); 33 | $('#submit').removeAttr('disabled').text('Run Test'); 34 | } 35 | 36 | // show/hide results 37 | if (xhr.responseText == '') { 38 | $('#response').hide(); 39 | } else { 40 | $('#hosterror').removeClass('error'); 41 | $('#response, #results').show(); 42 | } 43 | 44 | // output response 45 | if (xhr.responseText == 'Unauthorized request') { 46 | $('#results').hide(); 47 | $('#hosterror').addClass('error'); 48 | } else { 49 | $('#response').html(xhr.responseText.replace(/
