SJVBBS W6RAY
by Ray Quinn 28 Oct '13

28 Oct '13

This is a quick message to my forwarding partners that on Sunday, October 27, 2013, the SJVBBS (W6RAY) BBS will be offline for a short time. The BBS will be moved to a Raspberry Pi with two TNC-Pis connected to it. This setup will be located entirely at the repeater site (Park Ridge) instead of via remote. The gateway IP address will remain the same as will the AMPR IP addresses. The setup is currently in testing using a different alias and SSIDs at ground level. If the test is successful, then it will be installed at the repeater site. -- --- 73 de Ray Quinn W6RAY Visalia, CA DM06ih SJVBBS W6RAY 44.2.10.1

Probably the best bet is to get an old HUB or Switch, rip out all the electronics except the power supply, and cut holes to fit the desired number. There are also larger-scale custom made solutions, e.g. here: http://blog.raspberrycolocatie.nl/raspberry-pi-colocation/ I have a colocated Pi there. Rob

advertised services
by kb9mwr＠gmail.com 28 Oct '13

I stumbled into a useful function that the Hamnet/HSMM folks have: http://hsmm-mesh.org/hsmm-mesh-forums/view-postlist/forum-1-general/topic-5… Maybe there is a way to do (code) something similar for the more traditional nodes on the amprnet. Advertising what is out there on a network seems to be a major issue at least in my eyes.

Has anyone seen one of these yet? http://www.mouser.com/new/Intel/intel-galileo-development-board/?utm_source… Looks like Intel is going after the Pi market with a processor that's half the speed of the Arm in PIs. -- 73 de Brian Rogers - N1URO email: <n1uro(a)n1uro.ampr.org> Web: http://www.n1uro.net/ Ampr1: http://n1uro.ampr.org/ Ampr2: http://nos.n1uro.ampr.org Linux Amateur Radio Services axMail-Fax & URONode AmprNet coordinator for: Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, Pennsylvania, Rhode Island, and Vermont.

Raspberry Pi vs. Beagleboard
by Geoff Joy 28 Oct '13

28 Oct '13

Looking into networking some XBee Pro 900 Zigbee modules into a mesh network on 902-928 MHz. I have the Digi development package and it looks like I will need to either invent a TCP/IP stack for PC thru USB to the Digi XBIB or else host the S3B radio on Raspberry Pi or Beagleboards. What are the groups thoughts on pros/cons on each?

Re: [44net] Raspberry Pi

I am not sure that overclocking is relevant to NAND flash. The issue is quality control for the device. NAND cells are simple and the process drives reliability significantly. Vendors pay per quality, which translates to a number of cycles the device will endure. Well known brands demand and get better dies. Overclocking NAND will result in timing violations that will lead to failed commands - but it will not damage the die. This is different from the traditional overclocking to death of CPUs. The order of magnitude of power makes a significant difference.

Have you studied the Compatibility list... Some are shown to be a bad choice.. Some Kingston are listed as such. My first two SD cards I got from Fry's Electronics and they were I think, PNY brands. PNY I have found even their USB Sticks are junk.. But the two I got were only $4 ea.. Bad choice for the Pi. One lasted a few weeks the other until I had a sudden power outage about 6 weeks into it. I now have 2 Kingston SDXC Card 128GB Class 10 SDX10V/128GB Running on TWO pi.. Or Pi Squared.. lol One is under heavy abuse.. I have tried experimenting with sudden power outages, and constant read writes on one unit... And it has not suffered any issues.. In Fact I even tried it from -20F to +140F for S&G's They are NOT OVERCLOCKED. The other runs w9hu BBS Linbpq.. What do you use to image the SD card I used to use Windows program WinDisk32 .. I think this is the biggest issue with the Pi SD Cards.. At least I have had no issues with mine since I stopped that practice. Also what are you using that requires an external HUB.. You can also connect a TNC (other serial devices) to the GPiO port instead of the USB. Have you tried a PiTNC yet? Makes good topping.. :) it is the same size and sits atop the Pi. Like Icing!! 73 Jerry N9LYA PS I ll try to get back one the conv server as time permits.. _________________________________________ 44Net mailing list 44Net(a)hamradio.ucsd.edu http://hamradio.ucsd.edu/mailman/listinfo/44net http://www.ampr.org/donate.html

I have been running a test pi 128gb SD .running for 3 months. No issues with constant abuse...

This way we can have a decent CPU which is also low power in electricity not low in computing power (about 30 watts total). I think the RPi is only good in portable apps, but then again the SD Card is a major handicap. It could be good for applications that are not 24/7/365, such as an event where an AMPRnet GATEWAY is desired only for a few hours or maybe a few days max. If you operate the SD Card for more than a few days, it might get destroyed from the constant write of log files, updating databases etc. Can we have a system with no writting on the disk all the time? I'm not sure. 73 de Demetre SV1UY On Wed, Oct 23, 2013 at 12:26 AM, K7VE - John <k7ve(a)k7ve.org> wrote: > (Please trim inclusions from previous messages) > _______________________________________________ > Yes, the Pi boots from the SD, but one can put files on an attached drive, > especially swap, database, and logs.

Don't buy crappy SD cards - i.e. PNY. That is especially true in an application where it's used 24/7 as a solid state drive. Wear leveling in flash is very important and crappy flash won't endure.

Anyway here are my experiences. I have several Pi's in use. I have had a lot of head aches with PNY SD Cards. They go bad in rather short order. I have had a few Sandisk cards that have been in use just over a year. I have yet to have a problem with Sandisk. _________________________________________ 44Net mailing list 44Net(a)hamradio.ucsd.edu http://hamradio.ucsd.edu/mailman/listinfo/44net http://www.ampr.org/donate.html

DNS A Records Missing
by lleachii＠aol.com 22 Oct '13

22 Oct '13

All, I noticed that all of my DNS A records recently dissappeared. Has this occured to anyone else? At this time, my AMPR services are only rechable by IP address. The CNAME records in the DNS still exist; but most point to the missing ampr.org. A records: kb3vwg-001.ampr.org (44.60.44.1) kb3vwg-002.ampr.org (.2) kb3vwg-003.ampr.org (.3) kb3vwg-006.ampr.org (.6) kb3vwg-007.ampr.org (.7) kb3vwg-010.ampr.org (.10) kb3vwg-011.ampr.org (.11) kb3vwg-012.ampr.org (.12) -Lynwood KB3VWG
