Arghhh - Help
by James Pluck 11 Dec '07

(I apologise for the spam if you've gotten this twice. I think the email I originally sent it from is not subscribed to this list). Hi all! I'm in a bit of a bind. We're experiencing very poor connectivity at the moment from Slingshot. We're lucky to be able to stay online for more than 3 minutes at a time. I've just called Slingshot support and a very bored woman who sounded like it was beneath her to even talk to me was very unhelpful. refused to run any checks on the line or check logs or anything at their end unless I tried an alternative router on the line. She basically wanted me off the phone as fast as possible - presumably so she could get back to her WoW game or Puzzle Pirates or something more important than actual customer support (I tell you - if we had someone who behaved like that to customers at Quicksilver they'd be on notice pretty bloody fast!) Anyway - does anyone have a spare adsl router that I could borrow for a day or so to do some troubleshooting and see if it is my problem or Slingshot's problem. I'm in the process of choosing another provider because we've not been hapy with the service from Slingshot for some time but I'd kinda like to work out if it's a hardware issue or a connection issue before we switch. If I had the knowledge and the skills I'd probably just bite the bullet and rewire the jackpoints in this house - the current phone wiring seems a little amateurish - but we've had no troubles with any telecommunications services up until a couple of weeks ago. I have a drum of cat 5 but no skills on how to use it - *sigh* anyways - if anyone has a spare serviceable adsl router they would be willing to loan me I would be most grateful!

Network latency simulation
by Glenn Ramsey 28 Nov '07

28 Nov '07

Hi, In order to test some software I am developing I need to introduce a network delay between a machine and the rest of my LAN. After a bit of web searching I discovered that this is supposed to be simple to do, you just set up Linux as a transparent bridge and use the iproute tools to simulate network behaviour. However I can't get it to work how I want. I have an old AMD K6/500 box with 2 10bT ethernet cards running Xubuntu 7.10. One card is connected to my office LAN switch and the other to a hub, like this: MachineA---switch---eth0/bridge/eth1---hub---MachineB I have installed bridge-utils and iproute and I have configured the bridge machine according to the bridge-utils documentation by removing the eth0 and eth1 entries and adding a br0 to /etc/network/interfaces : auto br0 iface br0 inet static address 192.168.1.251 network 192.168.1.0 netmask 255.255.255.0 broadcast 192.168.1.255 gateway 192.168.1.1 bridge_ports eth0 eth1 This works fine and MachineB can get an address via DHCP and see the rest of the network. Now I need to add a delay so that all traffic between MachineB and the rest of the network has some latency. In order to add a delay, according to [1] I just need to do this: $ tc qdisc add dev DEV root netem delay 100ms I have done this for various combinations of eth0, eth1 and br0 but it only seems to delay traffic to and from the bridge itself, not traffic being relayed through the bridge. Does anyone know how to set this up to delay traffic going through the bridge?

Wireless networking problem
by Leslie Katz 21 Nov '07

21 Nov '07

My wife has as a wireless access point an Apple Airport Express that she uses with her Mac. It's set up with WPA for security. I'm am trying to use the thing as well, but am having difficulties. I have 2 laptops with wireless cards, one running Windows XP Media Centre Edition 2005 and one running Damn Small Linux 4. Generally speaking, the Windows laptop connects automatically to the wap when I boot it up. With the Linux laptop, it's very much hit and miss (with more misses than hits). When the Linux laptop is connecting, I first use wpa_supplicant to connect to the wap, followed by pump to configure the interface and all is well. When the Linux laptop isn't connecting, wpa_supplicant doesn't work and when I scan for waps using iwlist, I get a list of neighbours' unsecured waps, but no reference to the Airport Express. I can have the two laptops sitting side by side, the Windows one happily using the wap, while the Linux one isn't even aware of its existence. I'd be very grateful for any suggestions as to what to do to get the Linux laptop finding the wap reliably. Failing that, I'd be very grateful for a pointer to some site where I'm likely to get help with my problem.

Re: [wlug] [nzlug] Laptops sans OS possible:
by Craig Box 19 Nov '07

19 Nov '07

On the subject of cheap Linux laptops, OLPC are currently running a "give one, get one" scheme: http://www.laptopgiving.org/en/give-one-get-one.php. The gist is pay $400US, give one laptop to a developing nation, and get one for yourself. I believe this may be the only way members of the public can get one of these machines, at least initially. Unfortunately it's only available in the USA and Canada. If anyone is interested, I am in Canada at present, and would be happy to deliver one or two on behalf of people in NZ. I'll be back there in early Jan, which should hopefully be just after delivery. Please contact me off-list and I'll see what I can do. Craig

Asus Eee laptop

You might have seen this selling for $599 at Dickies. It runs Linux and a good review at Ars Technica here: http://arstechnica.com/reviews/hardware/eee-pc-review.ars/1 My take on this device is that it's not as innovative as the OLPC and it isn't fully featured enough. Better to buy a second hand or cheap laptop. -- Web1: http://wand.net.nz/~iam4/ Web2: http://www.jandi.co.nz Blog: http://iansblog.jandi.co.nz
