###To install and configure mod_epp (on Ubuntu 14.04 LTS)

* `sudo apt-get install apache2`
* `sudo apt-get install apache2-threaded-dev`
* `sudo apt-get install apache2-utils`
* `sudo apt-get install apache2-dbg` (Actually I don't think this is needed, but while debugging I installed this too)
* Download [mod_epp 1.10](http://sourceforge.net/projects/aepps/)
* `tar -xzf mod_epp-1.10.tar.gz`
* `cd mod_epp-1.10`

**NB! Beacause Rack multipart parser expects specifically formatted content boundaries, the mod_epp needs to be modified before building:**

```

* `sudo apxs2 -a -c -i mod_epp.c`
* `sudo a2enmod cgi`
* `sudo a2enmod authn_file` (Will be used for non implicit authentication URIs, can be removed in the future)
* `sudo a2enmod proxy_http`
* `sudo htpasswd -c /etc/apache2/htpasswd test` (can be removed in the future)
* Type "test" when prompted
* `cd /usr/lib/cgi-bin`
* `mkdir epp`
* Copy the files from $mod_epp/examples/cgis to /usr/lib/cgi-bin/epp (once in production, majority of these scripts will not be needed (maybe only double the error script for failover))
* `sudo mkdir /etc/apache2/ssl`
* `sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/apache2/ssl/apache.key -out /etc/apache2/ssl/apache.crt`
* `sudo nano /etc/apache2/sites-available/epp_ssl.conf`

For development configuration, add:
```apache
<IfModule mod_epp.c>
  <Directory "/usr/lib/cgi-bin/epp">
    Options ExecCGI
    SetHandler cgi-script
  </Directory>

  Listen 700
  <VirtualHost *:700>
    SSLEngine on
    SSLCipherSuite ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP:+eNULL
    SSLCertificateFile /etc/apache2/ssl/apache.crt
    SSLCertificateKeyFile /etc/apache2/ssl/apache.key

    SSLVerifyClient optional_no_ca

    EPPEngine On
    EPPCommandRoot          /proxy/command
    EPPSessionRoot          /proxy/session
    ProxyPass /proxy/ http://localhost:8989/epp/

    EPPErrorRoot            /cgi-bin/epp/error
    EPPAuthURI              implicit
    EPPReturncodeHeader     X-EPP-Returncode
  </VirtualHost>
</IfModule>
```

For plain TCP EPP configuration, see below (may be useful for debugging purposes).

* `sudo a2ensite epp_ssl`
* `sudo service apache2 restart`

Try it out:

* Fire up your appserver on port 8989 (This setup is tested with Unicorn)
* `cd $mod_epp`
* `./epptelnet.pl localhost 700 -s`

You should receive the greeting from the registry server.  
Wait for the greeting message on the STD, then send EPP/TCP frame:

```xml
<epp><command>
  <login>
    <clID>test</clID>
    <pw>test</pw>
  </login>
  <clTRID>sample1trid</clTRID>
</command></epp>
```

* Run tests: `rake`
* Run all but EPP tests: `rake test:other`

Configuration on plain TCP EPP is as follows:

Add:
```apache
<IfModule mod_epp.c>
  <Directory "/usr/lib/cgi-bin/epp">
    Options ExecCGI
    SetHandler cgi-script
  </Directory>

  Listen  1701
  <VirtualHost *:1701>
    EPPEngine On
    EPPCommandRoot          /proxy/command
    EPPSessionRoot          /proxy/session
    ProxyPass /proxy/ http://localhost:8080/epp/

    EPPErrorRoot         /cgi-bin/epp/error

    EPPAuthURI implicit
    EPPReturncodeHeader     X-EPP-Returncode
  </VirtualHost>
</IfModule>
```

For debugging purposes, standalone CGI scripts can be used:  
This needs a static greeting file, so you will have to make /var/www writable.

```apache
<IfModule mod_epp.c>
    <Directory "/usr/lib/cgi-bin/epp">
        Options ExecCGI
        SetHandler cgi-script
    </Directory>

    Listen 1700

    <VirtualHost *:1700>
        EPPEngine On
        EPPCommandRoot          /cgi-bin/epp/command
        EPPSessionRoot          /cgi-bin/epp/session
        EPPErrorRoot            /cgi-bin/epp/error

        EPPAuthURI              /epp/auth/login

                AuthType Basic
