For a list of informations displayed by LCDsys have a look into the source. LCDsys ist quite easy to install: Step 1: Untar the archive (you are reading this file, so you probably already did that;) Step 2: Place the files "lcdsys"&"fwviolate" in "/usr/local/sbin" or where you like to have it and store the configurationfile "lcdsys.conf" in /etc/. You should also create the directory "/var/lcdevents". Step 3: Change "/etc/lcdsys.conf" to your needs (it is commented, don´t worry) Step 4: Place a call for "/usr/local/bin/lcdsys" in one of your init-scripts, perhaps you want to run lcdsys with a higher niceness. Step 5: Load the lcd-module as described in the webpage Step 6: Enjoy! LCDsys also reacts on certain situations: Files created in "/var/lcdevents" are executed as shellscripts and can be used to display a PPP-Connect to the user or display an firewall-violation. For that task, LCDsys also contains a script named "fwviolate". Place it in "/usr/local/sbin/" and add the following line to your "/etc/hosts.deny": ALL : ALL : spawn (/usr/local/bin/fwviolate %d %a) & If someone tries to break into your system, LCDsys will react and display the attacked service as well as the attackers IP-Number on the LCD. WARNING: Don´t make "/var/lcdevents" world-writeable! Commands aren´t ckecked, so an evil (l)user can simply send an mkfs to LCDsys. Feel free to send additions or bug-reports to tommie@gmx.net.
