Hosting checker

Shared hosting service (webspace) checker based on my personal demands.

This shell script runs on your terminal (Linux, Windows/Cygwin, OS X) and checks any FTP/PHP/MySQL hosting service/webspace by uploading PHP code and downloading its output. No SSH access is needed for the hosting service, it runs on your own terminal.

You can use it to

• choose hosting provider
• fix errors in an existing site
• prepare for traffic spikes
• reduce spam
• speed up a website

Checks

• domain name (only .hu TLD by parsing domain.hu website)
• website IP, reverse hostname
• nameserver hostnames, IPs, locations, "Domi" domain check
• MX hostname, IP, reverse hostname and its IP
• SPF record
• FTP TLS certificate (lftp with gnutls has a bug)
• webserver name, Apache modules
• keep-alive support
• MIME types (from the HTML5 Boilerplate project)
• HTTP compression
• HTTP Cache-Control header
• concurrent HTTP connections
• PHP version php-ng
• PHP memory limit
• PHP excution time limit
• PHP HTTP functions (for downloading)
• PHP Safe Mode, magic quotes, register globals
• PHP user ID and FTP user ID comparison
• PHP Server API
• PHP extensions
• PHP time zone
• MySQL version
• set up PHP error logging
• server CPU info
• CPU stress test
• disk benchmarks
• MySQL benchmark (TODO)
• total size of WordPress "autoload" options
• and a lot of manual checks (notices, links)

Output types

• HTML with clickable links
• a coloured text file for console (use less -r to view it)
• Bash parsable key-value pairs

Installation

1. Install dependencies: lftp (curl is not a full-featured fallback) bind9-host whois, optionally pip install ansi2html.
2. Download it: git clone https://github.com/szepeviktor/hosting-check.git && cd hosting-check.
3. Autogenerate config file: ./generate-rc.sh.
4. If you have WordPress installed you don't have to set up database access, wp-config.php will be read instead.
5. Start it: ./hosting-check.sh.

Cygwin on Windows

On Cygwin use apt-cyg and install lftp beside ncurses, wget, bind-utils, util-linux and whois.

apt-cyg install ncurses wget lftp bind-utils util-linux whois

To clone this GitHub repo you will need:

apt-cyg install git libcurl4

steps increments a variable from 1 to 25 million, shuffle shuffles and calculates MD5 sum of a string half million times, AES encrypts an MD5 sum 2500 times. You can find the source in hc-query.php

Company names are hidden intentionally. Times are in seconds.
