''Linux installation procedure:'' Thought I might document this, so I don't need to do so much work next time, and incase other people need something to follow. If you find any mistakes or an easier way to do things, please leave a note!



	* Install OS

	* Recompile kernel - disable PCMCIA support, ensure wireless support is on.

	* Install pcmcia_cs/hostap/orinoco_cs - extract source files for pcmcia_cs; extract hostap files; copy files from hostap "driver" directory to pcmcia_cs root directory; extract orinoco_cs files; copy *.c and *.h files into pcmcia_cs wireless directory; follow normal pcmcia_cs instructions for install; add config settings to /etc/pcmcia/wireless.opts (note: WL200 MACs begin with 00:50:8B, and Enterasys' with 00:E0:63); edit /etc/sysconfig/pcmcia to look like:



	 PCIC=i82365 %%%	 PCIC_OPTS="extra_sockets=1 irq_mode=1" %%%	 PCMCIA=yes



	* allow pings - add to rc.local: echo 0 > /proc/sys/net/ipv4/icmp_echo_ignore_all

	* allow remote access - add local machines to /etc/hosts.allow eg.



	 ALL:192.168.0.0/255.255.255.0



	* DHCP server - install dhcp_common RPM from CD1, dhcp_server RPM from CD2; update /etc/dhcpd.conf with settings.

	* LCD display - install lcdproc. Now what a PITA this was. It continually crashed, apparently as it started reading the /etc/LCDd.conf config file. Quick fix: delete config file, specify driver to use on command line (for me this is LCDd -d HD44780) and edit source for the driver so the defaults match the system.

	* Temperature display - I like knowing that everything is running well. LCDsensors is a perl script that uses lm_sensors to display temps on the LCD. Very cool! Also using lcdproc's default client to show typical mem usage and uptime info (you wouldn't believe it - perl scripts crash v0.4.3 of lcdproc. Now running v0.4.4rc and all seems well.)

	* FreeSWAN for IPsec tunnels with Windows clients - this gets it's own wiki page [FreeSWANandWindowsHowto here] because of the amount of explination required.
