RHEL cluster question...

by David Hardy

Greetings, fellow Linux lovers; Ran into a little situation today where we need to cycle power/reboot a bunch of nodes that are down and out, by telnet to the relevant terminal server ports and the advanced management module. This involves multiple consoles, windows, command line, GUI, the works, as follows: Subject: RHEL cluster, 4.0 through 5.3. Issue: How to find IP addresses of terminal server ports which service individual nodes which are down and out. (need to telnet to them for troubleshooting/maintenance/rebooting) And: IP address and/or hostname of advanced management module which runs on the clusters . Some clusters have a "magic decoder ring" file that gives this information; most don't. Any thoughts? Workaround so far has been via eyeballing racks of blades and doing various arithmetic problems in our heads.

Looking for DDR 333 (PC2700) 512mb or 1gb mem

by John Stoffel

Guys, I've got an old home system for the kids. Works fine, but I've only got 768Mb of RAM in it. Anyone got any 512Mb or 1Gb DIMMS they want to sell? DDR, PC2700 is what I need. It's around $30/ea for 1Gb Dimms on newegg, which just isn't justified. It's almost more cost effective to get a new motherboard/cpu/RAM for this system instead. Thanks! John P.S. My Tivo, Series 2 has died finally, after 8+ years. I can't get my original 40Gb disk and mfstools 2.0 backup image to boot. Sigh... could be a power supply issue, but again, is it worth the money to fix or should I just get a premiere instead? --

Linux Ham Radio CD available for download

by Andy Stewart

Hi Everybody, I have created a remastered Linux CD of Ubuntu 10.10 which contains a selection of Amateur Radio software. Several of you were kind enough to beta test this CD and offer feedback, for which I thank you. This CD has been released and is now available for download from SourceForge: http://kb1oiq-andysham.sourceforge.net/ The software selection is optimized for older x86 32-bit computers that have at least a 1GHz processor and 256MB of memory, but naturally, if you have more than that, the software will work just fine. It uses the icewm window manager, and contains a web browser, graphical file manager, text editor, and other related tools. A short(!) list of the available Amateur Radio related software: aa-analyzer.pl - used with RigExpert AA-xxx antenna analyzers cqrlog - a full featured QSO logging program fldigi - digital modes such as PSK31 flmsg - companion to fldigi, a simple forms management editor for standard message formats flrig - rig control flwkey - modem program for the K1EL Winkeyer series flwrap - companion to fldigi, file encapsulation / compression Fl Moxgen - Moxon Rectangle antenna design program gpredict - satellite tracking grig - rig control software hamlib - radio control library ibp - HF beacons pskmail - send email via PSK31 qrq - CW callsig practice qsstv - SSTV sunclock - track day/night line on Earth svxlink - Echolink client (qtel) TQSL - used with ARRL Logbook of the World TQSL Cert - used with ARRL Logbook of the World wsjt - weak signal communication wspr - weak signal communication xastir - APRS mapping xcwcp - CW code practice xdx - DX cluster TCP/IP client xlog - simpler QSO logging program xnec2c - antenna modeling software xwxapt - display APT images from weather satellites FL_Moxgen and aa-analyzer.pl were written by yours truly and released under the terms of the GNU General Public License (version 3). Please feel free to pass this along to other interested parties.

The SATA Model was sold, the IDE burner does have alot of hours, but it always worked like a charm. I have a stack of 3 optical drives, you can have your pick out of the lot. And i do have a 2nd SATA DVD Burner thats perhaps, a year old, used 2-3 times? I'd have to yank it out of my server. I'll send you an email tomorrow to let you know what i have left over.
