[nzlug] Wireless goodness - suspend odd.

[Simon Bridge]

Recap: I have 4 hp/Compaq nx5000 lappies, a Lynksys wireless router, and
a d-link wired router/ADSL-modem.

I have the lynksys plugged into the dlink - making the wireless network
a subnet off the wired one. It's configured for WAP, and I can restrict
access by MAC address if I want.

Setting up wireless in the laptops was a breeze - there was some
confusion when two of them refused to have anything to do with the wifi
cards, but I saw a "wireless access" button by the kbd. Pressing this
worked the correct magic.

On a side note - activating the wifi under windows causes a cool blue
LED to glow. Doesn't happen in Ubuntu and I have no idea how to set it
up (or even if it's possible). It's not essential, but would be nice.

The lynksys was actually pleasant to configure - especially after the
dlinks clunky interface - no javascript, each page loads fast and slick,
there is an explanation of each option in a sidebar. But it doesn't talk
down to you: perhaps they figure that anyone using the http interface
has some ability? There is a setup "wizard" for Windows users which
stops just short of baby-talk.

Anyway, all set up with samba shares running, all machines can talk to
each other. I think NFS shares need to be explicitly mounted... anyway,
just enabling them doesn't do anything in the network directory.

Machines on the wired lan cannot talk to machines on the wireless and
reverse... have to see about that. But the internet access is fine. And
the wireless machines can ping each other by their hostnames, which I've
never managed on the dlink.

Which leads to the thought - I could just stick all the machines through
the lynksys, and use the dlink as a DMZ. Is it worth setting the DMZ
option, or should I leave it as a normal LAN?

Suspend is weird... only one machine reliably suspends and recovers,
that's the dual-boot machine. I'll have to check what's different -
that's probably the one I set noapic nolapic... that machine will go
down to hibernate but recovers to a black screen. However - windows
won't hibernate at all: not even the option! So I figure I'm ahead.

Now... I get to find out what's involved in setting up a network game:
sounds like it would be a nice exercise for the end of this course!

I could set up one machine as an ssh server, and do a wee security
lesson. But is there any point? There seem to be no routine services
that use this.
