DSL testing
by Keith Wright April 10, 2007

April 10, 2007

After several years of near flawless working, I am starting to have trouble with my DSL connection. A few times per year the modem would lock-up. It was rare enough that I did not worry much, I figured it was due to lightening or cosmic rays. In any case, it was rare enough that I could think of no way to debug it, and there seemed to be no real reason to, the power went out more often than the DSL. Lately it has been happening several times a day, I just got done with a burst of about ten consecutive lock-ups. I will be browsing the web, or something and it will just quit working. Ping of the ISP's nearest computer (by IP addr) does not work. I go to the modem, pull out the power plug, wait a few seconds, plug it in, wait for it to boot up, and it works again until the next time. I complained to the ISP (Speakeasy) and the nice guy there said: > I had a look at your circuit and see a sync at 1536 > kbps Downstream / 384 kbps Upstream with decibel > margins of 2.0 dB Downstream / 17.0 dB Upstream. The > downstream decibel margins are very low and as a > result, your line is incrementing heavy errors. I asked if I could see these numbers myself, so that I could try some re-wiring to see if it made the problem better (or worse). He said: > You won't be able to see real time Layer 2 stats of > your circuit, as this information is accessed from > the DSLAM in the Central Office. But I know I have heard some of you talking about statistics gathering programs for network performance. Does anyone know of a program that might help to see how well a DSL line is working, or other diagnostic tools for this? -- Keith

Hi Andy, See if "evdev" is loaded, then try reading the various /dev/input/event* nodes. I have a USB keyboard here. Oh neat, under 2.6.19, they even give you a path that matches the device ids, # od -x /dev/input/by-id/usb-1241_1203-event-kbd (tap tap tap...) 0000000 92a9 460e 0000 0000 36dc 000b 0000 0000 0000020 0001 001c 0000 0000 92a9 460e 0000 0000 0000040 36e0 000b 0000 0000 0000 0000 0000 0000 ... C code, #include <linux/input.h> int keyboardFd = open(kbdev, O_RDWR); struct input_event ev; int n = read(keyboardFd, &ev, sizeof(ev)); See the fields in ev, you'll get events for press/release, keycode, etc. Have fun! -Jamie > > I'm wondering if Linux has any software that would read the value from a > barcode scanner and do something with it.

Gigabit NICs for Linux
by sageman＠WPI.EDU March 31, 2007

March 31, 2007

All, Recently, I've been looking to upgrade my current network setup and make the push to gigabit. At the moment, I'm looking for any suggestions on gigabit NICs that folks have got working under the 2.6 kernel, preferably without too much effort. I'm currently looking at the Rosewill RC-400, which supposedly uses the r8169 module. Any one happen to have any luck with that? Additionally, I'm looking for a gigabit switch. Only need like 4-8 ports and would like it, again, to work very easily. Never used a switch, just hubs and routers. Right now, have a hub hooked into a router. From what I understand, if I replace the hub with a switch, it should *just work*. Basically, a switch is like a hub, but with full duplex support and maybe some fancy QoS features or something, right? My plan is to plug the high bandwidth internetwork connections into the switch which then connects into my router and through to a cable modem. Basically, fast connection on the network for transferring files, streaming and such, but, when it comes to the internet, cable modem is the bottleneck, so who cares if the router supports gigabit, right? Does this sound reasonable to you network folks out there? Thanks for all your help! Carlton Stedman

Seeking help with a USB barcode scanner
by Andy Stewart March 31, 2007

March 31, 2007

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 HI everybody, Does anybody in the group have any experience using a USB barcode scanner with Linux? Its tough to google for "barcode scanner" since each term brings up its own set of things which aren't what I seek. In particular, I have been loaned a USB barcode scanner which is made by PSC, Inc. with model number QS2500. When I plug it into my laptop, the USB vendor and device IDs are 04B4:0101. I looked this up on the Linux USB devices website and it has multiple references (mostly to USB keyboards). I think this device is being handled as a USB HID device, but I'm not certain. I'm wondering if Linux has any software that would read the value from a barcode scanner and do something with it. If I knew which device file was used, maybe I could "cat <devfile>" and see some output when I scanned a barcode. Note that there are several examples of software for printing barcodes, but that's not what I need (at least not yet). Any help would be appreciated. Thanks!

I have a new digital camera I haven't even used yet. I'd be more than happy to bring my camera. I'm curious to understand, will these be publicly viewable pictures, or *only* viewable to those who have your key? (P.S. I've never made a key before, so this is a good topic for me.)

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 HI Everybody, We appear to have a choice of meeting topics for April: 1) PGP Key signing party 2) My talk about the USB Delcom driver that goes with this piece of hardware: http://www.delcom-eng.com/productdetails.asp?productnum=802004 I'd rather move my talk out to May, but I could do it for April if that what folks desire. If we do the key signing party, I am wondering if Eric and Chuck would like to team up to run it. If so, does the April meeting work for you? Thoughts?
