Session monitor

Installation

For security reasons, the client portion of the session montior may run on one or more external public machine(s). On these machines, install:

Perl (at l east 5.004_05 for the 5.004 series or 5.005_03 for the 5.005 series. Don't enable experimental features like threads or the PerlIO abstraction layer.)
FS::SessionClient (copy the fs_session/FS-SessionClient directory to the external machine, then: perl Makefile.PL; make; make install)

Then:

Add the user `freeside' to the the external machine.
Create the /usr/local/freeside directory on the external machine (owned by the freeside user).
touch /usr/local/freeside/fs_sessiond_socket; chown freeside /usr/local/freeside/fs_sessiond_socket; chmod 600 /usr/local/freeside/fs_sessiond_socket
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
```
fs_session_server user machine
```
on the Freeside machine.
- user is a user from the mapsecrets file.
- machine is the name of the external machine.

RADIUS
Web
- Copy FS-SessionClient/cgi/login.cgi and logout.cgi to your web server's document space.
- Use suEXEC or setuid (see install.html for details) to run login.cgi and logout.cgi as the freeside user.
Command-line
```
freeside-login username ( portnum | ip | nasnum nasport )
```
- username is a customer username from the svc_acct table
- portnum, ip or nasport and nasnum uniquely identify a port in the port database table.

Sesstion start - The command(s) specified in the session-start configuration file are executed on the Freeside machine. The contents of the file are treated as a double-quoted perl string, with the following variables available: $ip, $nasip and $nasfqdn, which are the IP address of the starting session, and the IP address and fully-qualified domain name of the NAS this session is on.
Session end - The command(s) specified in the session-stop configuration file are executed on the Freeside machine. The contents of the file are treated as a double-quoted perl string, with the following variables available: $ip, $nasip and $nasfqdn, which are the IP address of the starting session, and the IP address and fully-qualified domain name of the NAS this session is on.
