IP Masquerading for USB ethernet
by Brian Doob 21 Dec '03

21 Dec '03

I have a Compaq iPaq with Linux installed on it (see http://opie.handhelds.org/) and it is connected to my Gentoo Linux box with USB ethernet. The Gentoo box is connected to an Ovislink router (with a DHCP server) via regular ethernet. I want the hanheld to be able to talk to the net via the Gentoo box. I have not been able to get IP masquerading to work under Gentoo. I would prefer to have the handheld get its IP address from the router (and have the Gentoo box just forward the packets). Does anyone know how to get this working? Here is some info about my situation: # ifconfig eth0 eth0 Link encap:Ethernet HWaddr 00:20:ED:B8:91:55 inet addr:192.168.1.1 Bcast:255.255.255.255 Mask:255.255.255.0 UP BROADCAST NOTRAILERS RUNNING MULTICAST MTU:1500 Metric:1 RX packets:3340 errors:0 dropped:0 overruns:0 frame:0 TX packets:3557 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:3330687 (3.1 Mb) TX bytes:448922 (438.4 Kb) Interrupt:11 # ifconfig usb0 usb0 Link encap:Ethernet HWaddr 4E:DC:69:01:CA:EF inet addr:192.168.1.200 Bcast:192.168.1.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:25 errors:0 dropped:0 overruns:0 frame:0 TX packets:7 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:980 (980.0 b) TX bytes:574 (574.0 b) # iptables -t nat -I POSTROUTING -j MASQUERAQDE -s 192.168.1.3/16 iptables v1.2.8: Couldn't load target `MASQUERAQDE':/lib/iptables/libipt_MASQUERAQDE.so: cannot open shared object file: No such file or directory # uname -a Linux proton 2.4.23-ck1 #1 Thu Dec 4 19:21:52 CST 2003 i686 AMD Athlon(tm) XP 1800+ AuthenticAMD GNU/Linux This is how I bring up the network to the PDA: modprobe uhci sleep 1 insmod usbnet ifconfig usb0 192.168.1.200 netmask 255.255.255.0 pointopoint 192.168.1.3 up route add -host 192.168.1.3 usb0 If anyone is interested in the really gritty details, I have attached the config file for my kernel. Does anyone know what I need to do? Thanks. -Brian

IBM Linux commercial
by John Lange 15 Dec '03

15 Dec '03

On another local linux mailing list, someone posted this link to a IBM commercial for Linux which was apparently spotted on CNN. http://www.ibm.com/open/ I feel this is pretty significant news. A large marketing campaign from a very large and credible source designed to bring Linux to "top of mind". Apologies for the cross posting for those of you who are also members of the other list.

RBC rethinks SCO investment
by John Lange 09 Dec '03

09 Dec '03

An update to the original story that RBC is investing $50 million in SCO: http://www.globetechnology.com/servlet/story/RTGAM.20031209.gtscodec9/BNSto… Unfortunately, "rethink" does not mean they are pulling out of the investment, only that they have placed some conditions on the deal. -- John Lange BigHostBox.com ltd (204) 885 0872 Toll free: 1-866-690-8297

CD, VCD & DVD Burning
by John Lange 03 Dec '03

03 Dec '03

At a recent MUUG meeting someone was asking about burning VCDs (Video CDs). I believe the consensus at the meeting was that burning under Linux was comprised of a hodge-podge of various command line tools for converting video formats and burning making it quite difficult at best. I recently stumbled on the following software: http://www.k3b.org/ which seems to bring everything under one roof and claims to do CD, VCD, and DVD burning all in one application (it does not appear to be just a GUI front end to command line tools). However, I do not currently have a burner to test it with so I was hoping someone from the group could give it a whirl and report back on success? Thanks. -- John Lange BigHostBox.com ltd (204) 885 0872 Toll free: 1-866-690-8297

Royal Bank invests 50 million in the SCO Group
by John Lange 01 Dec '03

01 Dec '03

The following story indicates that the Royal Bank has just invested US $50 million in the SCO Group. http://www.linuxinsider.com/perl/story/32251.html As I simply can not stomach the thought of in any way helping SCO I am forced to move all of my business and personal accounts including RRSPs to another institution. Aside from the political issue I don't think it says much for whomever is making the investment decisions over at RBC. SCO has no future so they just threw away 50 million dollars. On a related note, the same story indicates that CIBC pulled out of all of its SCO shares in June. -- John Lange BigHostBox.com ltd (204) 885 0872 Toll free: 1-866-690-8297

water clock
by millward 19 Nov '03

19 Nov '03

I was wondering if anyone out there might be able to tell me how these water clocks work. All you do is fill it up with mildly salty water, and that's what it runs on. The one I've got has been keeping good time for about 5-6 days now. Once in a while a little bubble comes up, so it must be producing some kind of waste gas. I'd like to build my own circut based on whatever devices run this clock, just for fun. Would anyone know what kind of electronics run on water? And where I could get them? I didn't buy my clock through the net, but it's selling at: http://www.computergear.com/waterclock.html All the site says about how it runs is: "The fuel cell extracts electrons from the electrolyte forming a steady stream of electrical current that drives the clock." That's all very well, but it doesn't tell me what the name of the fuel cell is, where I can get them, and how I can build a curcit based on the fuel cell's power.
