Voyage gives you a nifty script to install it on compact flash, with appropriate targets for specific hardware, e.g., alix, standard pc, soekris. The alix target has all the appropriate hardware support, i.e., geode cpu, support to control the LED's, etc. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".

But Voyage is basically Debian designed to run in RAM, this way you don't keep writing to the compact flash card. You can apt-get anything. I guess you could also boot regular Debian off of a USB disk. The bigger boards also have a 44 pin IDE connector.

You ever hear of the PC Engines Alix boards? Link: http://www.pcengines.ch/alix.htm They come in a variety of configurations. Generally, you get x86 Geode CPU, 1 to 3 ethernet ports, more than 1 USb port, mini-PCI slots, 256MB RAM, a DC jack that supports anywhere from 7v to 20v DC, serial ports, and the ability to run Coreboot (formerly LinuxBIOS). You could could Voyage Linux directly from a compact flash. Link: http://linux.voyage.hk/ It's basically Debian for x86 embedded devices. It keeps apt and runs the entire OS is RAM.

Just as an aside, there seems to be a varierty of usb to ethernet connectors, at a variety of different prices. Some seem to be so cheep that they can be little more than a usb connector and rj45 connector.

I think that is the answer, limit the switch to have the cable modem, plug computer and existing cable router on it. the "lan" side of that cable router will be where I connect everything else and can use dhcp with confidence there. I presume nfs (which I have not used before) will still work connecting the plug computer as an nfs client throught the router (which is a NAT device) to one of the backend servers running a large disk and the nfs server end if I port forward correctly.

Could this be solved by using a dhcp server (or forwarder to plug computer server) on the wireless AP? signature.asc Description: Digital signature

No, it can work. You are just confused. The switch does not know anything about IP addresses. It understands ethernet MAC addresses. $ /sbin/ifconfig eth0 Link encap:Ethernet HWaddr 00:24:1d:28:73:b6 inet addr:10.1.4.55 Bcast:10.1.255.255 Mask:255.255.0.0 inet6 addr: fe80::224:1dff:fe28:73b6/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:12194355 errors:0 dropped:173155950949126 See that HWaddr: field? That's a MAC address. It should be unique on every network interface. Routers are devices that make decisions on the IP level. Switches make decisions on the ethernet level. What you will have problems with is running DHCP, as you mentioned. Here's what you do: Get a USB-ethernet connector for your plug. Now you have two ethernet ports. One goes to the cable modem, one goes to your switch. Life is good. Alternatively, hardcode IPs for everything on that switch. You can either hardcode IPs for your wireless devices, or run DHCP on a separate subnet there. -dsr- -- http://tao.merseine.nu/~dsr/eula.html is hereby incorporated by reference.
