Grant temporary shell access to yourself when away from home or on dialup.

An easy way to give yourself temporary ssh access to your linux server from a remote location without having to modify your /etc/hosts.allow file to grant access and then again to remove access.

Also an easy way to give shell access to a dialup hostee without having to specify ALL of their ISP's dialup IP ranges.

These files are:
- index.php
a simple webpage that records your IP into a file that is
saved outside of your document_root folder, and is read by
the dipSCR script amd appended to your hosts.allow file, thus
giving you access from that remote location.
This file should be put in an obscurely named folder protected
by htaccess ( username/password )
- dipRUN
a cron job that executes the dipSCR script every 5 minutes
- dipSCR
a script that reads your remote IP ( after you load up index.php )
and appends that IP to your hosts.allow file for 5 minutes.

Check the README.txt file in the archive for some basic instructions on installation and use.

Requires:
CGI PHP
CRON

Recommended:
securely named ( and not advertised ) web accessible folder protected by htaccess
