Pound HTTPS Configuration

The following steps will guide you through the generation of a self-signed certificate for your ]project-open[ server.
During the process you will create:

• server.key: This is a 1024 bit random string ("private key") that uniquely identifies your server
• server.csr: This is a "Certificate Signing Request" file. You can send this to a Certificate Authorities (CA), or sign it yourself.
• server.crt: This is a "certificate" that certifies that server.key belongs to you.
• server.pem: This is the file that Pound needs to work correctly. A PEM file is a bundle of a the "server.key" priviate key and a certificate.

1. Generate an RSA private key for the server:
   openssl genrsa -out server.key 1024
   
2. Remove the passphrase from the key. Please make sure that nobody will have access to this file except for you. Otherwise the security of your server is at risk:
   cp server.key server.key.org
   openssl rsa -in server.key.org -out server.key
   
3. Create the Certificate Signing Request file, or CSR:
   openssl req -new -key server.key -out server.csr
   You will have to provide certain information for your CSR. Here are some sample values for ]project-open[:
   
   Country Name (2 letter code) [GB]: ES
   State or Province Name (full name) [Berkshire]: Catalonia
   Locality Name (eg, city) [Newbury]: Barcelona
   Organization Name (eg, company) [My Company Ltd]: Project Open Business Solutions S.L.
   Organizational Unit Name (eg, section) []:
   Common Name (eg, your name or your server's hostname) []: www.project-open.org
   Email Address []:webmaster@project-open.com
   A challenge password []:
   An optional company name []:
   
4. Now you could go to some Certificate Authority in the Web (for example: http://www.instantssl.com/ currently offers free certificates for 90 days) and sign your key there. As a result, you will receive a "certificate" file that you can save as "server.crt".
   
5. As an alternative you can sign the key yourself.
   The server.crt certificate will be technically valid. However, your browser will show a security warning if it encounters such a self-signed certificate:
   openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt
   
6. Verify your certificat. The following command should output some data, and not an error message:
   openssl x509 -in server.crt -text
7. Create a PEM file:
   openssl x509 -in server.crt -out server.pem
openssl rsa -in server.key >> server.pem
   ­
8. Now you can add a HTTPS listener configuration to your pound.cfg configuration file:
   ListenHTTPS
  Address 0.0.0.0
  Port    443
  Cert    "/etc/pound/server.pem"
End
   Older versions of Pound (<2.2) may require a different listener configuration, please consult the man-page of your installed version of Pound.

The new configuration will be come active after restarting Pound (/etc/init.d/pound restart).
You can execute "netstat -nlp" to list all network connections. In the upper part your should see something like this:

...
tcp        0      0 0.0.0.0:8000                0.0.0.0:*                   LISTEN      24804/nsd
tcp        0      0 0.0.0.0:80                  0.0.0.0:*                   LISTEN      375/pound
...
tcp        0      0 0.0.0.0:443                 0.0.0.0:*                   LISTEN      375/pound
...­

• ­ 0.0.0.0:8000: This is the AOLserver itself
• 0.0.0.0:80: This is Pound listening for unincrypted HTTP connections
• 0.0.0.0.443: This is the Pound HTTPS listener.

Pound will write any errors into /var/log/messages.
