#+title: ifconfig.php

* what
php script. shows your ip address, user agent, and related info.
same idea as ifconfig.me and ifconfig.co.

output as html (default), plain text, xml, or json. single values
on request.

* use
#+begin_example
live at ip.cmc.pub:
- ?q=text   all, plain text
- ?q=xml    all, xml
- ?q=ip     ip only
- ?q=ua     user agent only
#+end_example

#+begin_src sh
curl -L -X GET https://ip.cmc.pub/\?q\=text
#+end_src

apache rewrite so /ifconfig/xml works without the query string:

#+begin_src sh
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ifconfig$ ifconfig.php [L]
RewriteRule ^ifconfig/(.*)$ /ifconfig.php?q=$1 [L]
#+end_src

* develop
install php and composer. fedora:

#+begin_src sh
sudo dnf install php-cli composer
#+end_src

maxmind-db dependency:

#+begin_src sh
composer require maxmind-db/reader:~1.0
composer update
#+end_src

geolite2 database. not in the repo: maxmind-licensed, ~69mb, and stale
the day after you download it. sign up for a free maxmind account, then:

#+begin_src sh
https://www.maxmind.com/en/accounts/current/geoip/downloads
#+end_src

download GeoLite2-City in mmdb form and put GeoLite2-City.mmdb next to
ifconfig.php. without it the page still serves, minus the geo block.

dev server:

#+begin_src sh
sudo php --server localhost:8080 --docroot .
#+end_src
