"LMS" (LAN Management System) is a package of applications in PHP, Perl and C for managing LANs with MySQL, PostgreSQL or SQLite databases support. The main goal is to get the best service of customers at high provider's level. The main features in LMS are:
database of customers (name, surname, address, phone numbers, commentary and other),
database of computers (IP, MAC),
easy-ridden financial system and funds of network,
financial balances and invoices
sending e-mail warnings to users,
automatic billing,
generating of (almost) any kind of config file (i.e. ipchains/iptables based firewall script, dhcp daemon configuration, zone file for bind, static arp entries, oident, htb and more...)
visualization of internet link usage stats,
request tracker system (Helpdesk),
timetable (organizer).
All stuff was invented for administration of ASK NetX and there is still developed and tested.
LMS will not replace your administrator's skills. If you can't make so simple activity like installation or configuration, probably you'll cannot adjust LMS for your system. So, you must have knowledge about administration of UNIX systems.
