Lan Management System (LMS) On Debian Squeeze - Router Howto

x install-vsmart-2.0-en-64bit.sh
./install-vsmart-2.0-en-64bit.sh

The scripts will download necessary packages from debian repositories and my deb packages:

linux kernel 2.6.32 with patches: layer-7, imq, esfqiptables 1.4.8 with patches: layer-7 and imqiproute 20101221 with esfq patchppp 2.4.3 with mppe and mppc
pppoe 3.10 with mppe, mppc and kernel pluginpptpd 1.3.4 with mppe and mppc

All the packages are available for independent download from:

 http://files.v-smart.pl/v-smart-2.0/

You may view the scripts before executing to see what they exactly do. You have to write down the MySQL root password and type it when the install script ask for. After reboot you can go to the router GUI via browser. Simply open the router IP address in the browser. First time LMS will ask you for creating an admin account. Don't forget to check full access option for admin. Example configuration is available for view after installation. You have to set up your WAN bandwidth in the /router/router.conf file in kilobits-per-second. Default is 10Mbps.

How does it work? Network administrator adds clients, computers and tariffs (download and upload speed) into LMS. There is my daemon running in the background which checks if something was changed in the GUI configuration. If so, the daemon will update the configuration file for the firewall (/router/lms.conf) and reload firewall, NAT and traffic shaping. Firewall scripts and configs are in the /router directory. LMS GUI is installed in the /var/www directory. Other stuff (messages, daemon, etc.) are in /var/v-smart directory. Network configuration you can find in /etc/rc.local script.

Installed LMS is pure and unmodified. In the database there is vsmart table with to-do records that are read by the daemon in 3-second period. I added MySQL triggers to follow changes in the LMS tables. The triggers will update to-do records when something is changed in customers' devices configuration. Then the daemon makes a decision about reloading firewall, traffic shaper and NAT. Finally - changes in LMS GUI are set in the router almost instantly. This is the main idea of my project.

In the crontab there are periodicaly run some LMS scripts (stats, payments, host alive checking and other). Feel free to view or adjust /etc/cron.d/vsmart file.

List of router main functions:

- Dynamic traffic shaping on WAN port using IMQ with HTB/esfq and service priority,
- Static traffic shaping on LAN port (LMS tariffs),
- MAC
