###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
• 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:

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

  Listen 701

Note: Its best to go with two virtual hosts, one for test and one for dev, then you don't have to worry about quitting the dev appserver for running tests (because of colliding ports).

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 701 -s

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

<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

To see internal errors while testing EPP

• unicorn -E test -p 8989
• rake spec:epp

---

Configuration on plain TCP EPP is as follows:

Add:

<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.

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