Signup, self-service and reseller interfaces

For security reasons, the self-service interface should run on a public machine, not the backend Freeside server. On the public machine, install:

A web server, such as Apache (mod_ssl or Apache-SSL highly recommended)
SSH
Perl.
Text::Template
Storable
Business-CreditCard
HTTP::BrowserDetect
HTML::Parser
FS::SelfService (copy the fs_selfservice/FS-SelfService directory to the external machine, then: perl Makefile.PL; make; make install)

Then:

Set the signup_server-default_agentnum configuration value to a default agent number.
Set the signup_server-default_refnum to a default advertising source.
Add the user `freeside' to the the external machine.
Copy or symlink the fs_selfservice/FS-SelfService/cgi/ directory into the web server's document space. Optionally, customize the .html templates. "Entry points" (useful places to link to) are:
- signup.cgi - Signup
- selfservice.cgi - Customer self-service
- agent.cgi - Reseller interface
- passwd.cgi - Simple password-changing interface
- promocode.html - Promotional code pre-signup
- regcode.html - Registration code pre-signup
- stateselect.html - State selection pre-signup
When linking to signup.cgi, you can include a referring custnum in the URL as follows: http://public.web.server/path/signup.cgi?ref=1542
Enable CGI execution for files with the `.cgi' extension. (with Apache)
Create the /usr/local/freeside directory on the external machine (owned by the freeside user).
touch /usr/local/freeside/selfservice_socket; chown freeside /usr/local/freeside/selfservice_socket; chmod 600 /usr/local/freeside/selfservice_socket
Use suEXEC or setuid (see install.html for details) to run signup.cgi, selfservice.cgi, agent.cgi and passwd.cgi as the freeside user.
Append the identity.pub from the freeside user on your freeside machine to the authorized_keys file of the newly created freeside user on the external machine(s).
Run an instance of
```
freeside-selfservice-server user machine agentnum refnum
```
on the Freeside machine for each external machine.
- user is a user from the mapsecrets file.
- machine is the name of the external machine.

Optional:

If you create a /usr/local/freeside/ieak.template file on the external machine, it will be sent to IE users with MIME type application/x-Internet-signup. This file will be processed with Text::Template with the variables listed below available. (an example file is included as fs_selfservice/FS-SelfService/ieak.template) See the section on internet settings files in the IEAK documentation for more information.
Variable substitutions available in ieak.template and success.html:
- $ac - area code of selected POP
- $exch - exchange of selected POP
- $loc - local part of selected POP
- $username
- $password
- $email_name - first and last name
- $pkg - package name
