WiBSD main features

• WiBSD runs from memory, and boots from read-only mounted media
• contains many commands from the default FreeBSD installation; you can see the configuration file for the 1.x branch.
• system has a very small memory/disk footprint (but since we have root filesystem in memory, WiBSD needs at least 64M RAM). WiBSD can run directly above the disk/flashcard, but it's no longer a useful configuration for us since remote upgrade is then complicated.
• it's therefore very easily and safely remotely upgradable via cisco-like aproach
• all the configuration is managed from one place only. We use /etc/rc.conf, which is linked to a file located on writable media.
• see /etc/defaults/wibsd.conf to see how many things you can configure there; this file is self-documented and contains reasonable defaults whereever applicable. See the real wibsd.conf file.
• you can log as admin to easily perform an initial configuration (IP address and default gateway). You may use it if you have just some remote hands on the other side.
• WiBSD contains nice IPFW firewall system, configurable from /etc/rc.conf, of course. See fw_* variables in /etc/defaults/wibsd.conf file.
• safe reboot plugin checks the system before it's actually rebooted. In case of any problem, reboot is refused (you can of course overide it; use "-f" option if you need it).
• no web interface so far, only SSH. This system is designed for admins only.
• some 3rd party software is included - bash, iftop, isc-dhcp3-server, Links, NetSNMP, nmap, OpenVPN, PoPToP (PPTP server), thttpd, ttcp and ViM.
