Check if a server is responding to requests on ports 21, 22, 80 & 443

Uses nmap to check if a server is listening on the above ports. It assumes the target is active (i.e. it bypasses the potentially invasive nmap discovery stage). Here's the explanations of the port states recognised.

NB: it may take a few seconds for results to show.

Enter IP address or hostname (e.g. osola.org.uk)

Domain name directory service

Looks up the authoritative WHOIS server for the domain name then does a WHOIS lookup using that server.

Enter domain name (e.g. osola.org.uk)

Forward & reverse DNS lookups

Uses dig to search for all DNS records for the domain. You can usually get more details by entering an authoritative name server for the domain in the optional name server box.

Enter IP address or domain name

Enter a specific name server (optional)

Show web page source with headers

Returns the page headers plus the HTML source.

Enter web page URL

Show web page source with headers by IP address & host header

As above, but allows you to check a site is up on a server before the DNS has been changed or fully propagated. Useful for sanity-checking site moves.

Enter web page URL

Enter hosting server IP address

Generate Apache .htaccess passwords

Calculates different passwords on each run - none are stored.

Enter User Name

Enter Password

Confirm Password

Make a text file called .htpasswd - ideally in a non-web-served location. Add this line:

Make a text file called .htaccess in the directory to be protected. It should contain something like:


 # Your comment here
 AuthUserFile /server/path/to/.htpasswd
 AuthGroupFile /dev/null
 AuthName 'Your password dialogue box message here'
 AuthType Basic
 Require valid-user
