Re: [Wlug] Hardware Vendor Search (a bit off list)
by Jamie Guinan 08 Jun '07

08 Jun '07

I had a really bad experience trying to buy a 1U server from a vendor I saw in Linux Journal, thinking I'd support a "linux-friendly" company. Well, after they charged my CC, it took them 3 *weeks* to start the system burn-in, the system *failed* burn-in, they said it would take at least another week... so I finally told them to screw off and got my money back. I ended up buying a dirt-cheap 1U Celeron (Cybertron) from TigerDirect, which I colo'd with a Level3 reseller in Cambridge. Its been humming along for 2 years so far. So if you're willing forego the "value add" (pronounced with dripping sarcasm and doing the "quotes" motion with my fingers) that some vendors might provide, and you can install and configure your own Linux distro, you might try TigerDirect or another generic online vendor. -Jamie On Fri, 8 Jun 2007, Tal Cohen wrote: > Does anyone know a good, reliable, hardware vendor that they can recommend? > I need to purchase 4-7 2U servers and our existing vendor is dragging his > feet. > > > > Thanks, > Tal

Does anyone know a good, reliable, hardware vendor that they can recommend? I need to purchase 4-7 2U servers and our existing vendor is dragging his feet. Thanks, Tal

Seeking Linux help for area non-profit - compensation potential
by Mike Peckar 06 Jun '07

06 Jun '07

Please do not reply to the list or to me. Boylston's public cable access channel (WBAC) is seeking to expand its services and offer Video on Demand and video file upload and download services for its staff and eventually the community. They currently have their web site and email hosted with an ISP and they are happy with that, but the ISP cannot provide them with these new services. They are looking for help in installing and configuring a linux box off their private LAN for this purpose. They also need other general help with their setup including configuring and troubleshooting VPN connections via their netgear VPN/firewall, etc. These folks are sort of windows literate, and they recognize that Linux will provide them with the most secure and cost-effective solution to meet their growing needs at this time. Ideally, they are seeking Boylston residents, but they are willing to bring in help from outside their community. They are also able to reasonably compensate for the above mentioned services and/or barter for access to their fine production equipment. If you are intersted in learning more about video and television production, this may be well worth your effort. To express your interest, please provide a brief summary of your skills, your level of interest in supporting WBAC, and any compensation requirements to: Tom Martiska Staff(a)wbactv.org

Followup [Re: Follow-Up to Key Signing Party]
by Jamie Guinan 31 May '07

31 May '07

Ok, so I did, gpg --recv-keys ... [everyone's ID from the meeting ] gpg --fingerprint ... [ confirm fingerprints ] for key in ... ; do gpg --sign-key $key; done for key in ... ; do gpg --send-key $key; done Now "gpg --list-keys" shows all the keys I expected to see. And just now I did a "gpg --recv-keys <my ID>" and it said I had 6 new signatures, gpg: requesting key 103BA0B0 from hkp server pgp.mit.edu gpg: key 103BA0B0: "Jamie Guinan <guinan(a)bluebutton.com>" 6 new signatures gpg: 3 marginal(s) needed, 1 complete(s) needed, PGP trust model gpg: depth: 0 valid: 1 signed: 12 trust: 0-, 0q, 0n, 0m, 0f, 1u gpg: depth: 1 valid: 12 signed: 1 trust: 12-, 0q, 0n, 0m, 0f, 0u gpg: next trustdb check due at 2009-04-16 gpg: Total number processed: 1 gpg: new signatures: 6 I think that looks good.

a) UPS talk? b) APC-w-USB ?
by Doug Mildram 29 May '07

29 May '07

doug> I got an idea for a WLUG talk, having trolled the SW-devel-mail-list and used sparingly the excellent APC-UPS free sw at http://www.apcupsd.com I've got a small-enough APC SmartUPS and a laptop or 2 I could do this on. What I don't have (or can't yank out of the lab here at work) COULD USE....dont really NEED: ....an APC UPS with the more modern USB port....reasonably small. (the SW supports serial/"COM1" cable/interface, or USB/HID... I'm very weak on the HID stuff, but it probably just works.) So this lure is to see who does have apc w/usb... and wants to try-and-or-demo this. and When's the june meeting ? (I forget what month the party is.)

I think resource settings "reside" in the X server at run-time, so you could try manually adding those particular ones like so, (with queries before and after for testing), $ xrdb -query $ xrdb -merge ~/.gv $ xrdb -query Then run gv again. If it works, maybe you could add it to your X startup, however that works on your $DISTRO+$DESKTOP+etc... In the past I've also used ggv, which is gnome-ified gv. -Jamie

FW: gv & resource file in ubuntu feisty fox
by Bill Mills-Curran 25 May '07

25 May '07

I've searched and have not found the answer to this issue. gv in the Ubuntu feisty fox distro does not seem to observe the resource file. In particular the auto-refresh and reverse scroll do not work. My resource file is ~/.gv and contains: GV.reverseScrolling: TRUE GV.watchFile: TRUE GV.autoResize: FALSE This did work on Red Hat FC4, but the same file does not work in Ubuntu. Am I doing something wrong or have I found a bug? TIA, Bill

Cups, FC6, and networks, oh MY!
by Bill Smith 25 May '07

25 May '07

I have recently acquired an HP LaserJet 4MP. It's connected to the parallel port of my system running FC6 (with all current updates). The printer itself works great, so long as I am trying to print from localhost, but I'd like to share it to the other systems on my network. (These other systems include WinXP, Mac OS X, etc.) I've poked around a bit and found pointers on getting cups to work on other OSs (Gentoo, Ubuntu), but not Fedora Core. Would anyone have any pointers? I'm willing to post config file segments, if that will help-- just tell me what you need to see. Any help would be greatly appreciated. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- William Smith wsmith-at-chezsmith-dot-com Fall River, MA http://www.chezsmith.com "He played me like a fish...

How much is interchangeable between the 4M and 4MP? I know that my printer doesn't have anywhere for a JetDirect card: it's got a parallel, AppleTalk, and serial port at one edge on the back, and on the side, it's got two (empty) memory slots... I'm mostly wondering what I need to do to get FC6 to share this printer (that is, the LaserJet 4MP) with other computers on the network. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- William Smith wsmith-at-chezsmith-dot-com Fall River, MA http://www.chezsmith.com "Free will is an illusion.

Well, maybe one more sparc64 question....
by Ken Jones 25 May '07

25 May '07

Jamie, That posting you sent me is definitely my bug. The only difference is the revision level of media-libs-mesa. The poster claims that his problems were fixed with a emerge --sync the following morning. I have not been so lucky. -------------You and the bug report told me to eselect opengl. I did and this is what I get. kjones-sun2 temp # eselect opengl set xorg-x11 shell-init: error retrieving current directory: getcwd: cannot access parent dir ectories: No such file or directory !!! Error: Can't load module opengl Killed kjones-sun2 temp # ----------I then looked for a relationship between opengl and xorg-x11. kjones-sun2 temp # locate opengl | grep x11 /usr/lib/opengl/xorg-x11 /usr/lib/opengl/xorg-x11/include /usr/lib/opengl/xorg-x11/include/glxtokens.h /usr/lib/opengl/xorg-x11/include/glxmd.h /usr/lib/opengl/xorg-x11/include/glxproto.h kjones-sun2 temp # --------The posting also asked that I check glxproto.h as a logical link. kjones-sun2 temp # ls -l /usr/include/GL/glxproto.h ls: cannot access /usr/include/GL/glxproto.h: No such file or directory kjones-sun2 temp # --------So I just tried to find glxproto.h. It is real and 75729 bytes in size... kjones-sun2 temp # locate glxproto.h /usr/lib/opengl/xorg-x11/include/glxproto.h kjones-sun2 temp # kjones-sun2 temp # ls -l /usr/lib/opengl/xorg-x11/include/glxproto.h -rw-r--r-- 1 root root 75729 May 23 18:14 /usr/lib/opengl/xorg-x11/include/glxpr oto.h That seems very interesting and pertinent.

What is gentoo's equivalent of Red Hat's rpm? That's what gentoo's portage system (via the "emerge" command) does for you - downloads the tarballs, builds, installs, and keeps a record of what's installed under /var/db/pkg/<category>/<package>/ . Well, when it works. :) Look at /usr/portage/media-libs/libpng/*.ebuild, its fairly easy to get the gist of it if you know shell syntax. Did you do "emerge --sync" like some others suggested? I see a few libpng versions available, up to 1.2.16, $ ls /usr/portage/media-libs/libpng/*.ebuild /usr/portage/media-libs/libpng/libpng-1.2.14-r1.ebuild /usr/portage/media-libs/libpng/libpng-1.2.14.ebuild /usr/portage/media-libs/libpng/libpng-1.2.15.ebuild /usr/portage/media-libs/libpng/libpng-1.2.16.ebuild > --------------snip------------- > Lastly, how do you know that HAPPYMEAL is in the sun-hme module?

I got my sparc64 gentoo on the network
by ken jones 23 May '07

23 May '07

Thank you for suggesting that I compare two dmesg boot message outputs. "grep eth0" on the dmesg outputthat worked referenced HAPPYMEAL. The same 'grep' on the boot log that did not work had no HAPPYMEAL string. I had a 'CONFIG_HAPPYMEAL=m' line in .config. I changed it to 'CONFIG_HAPPYMEAL=y' and recompiled using genkernel. NOW MY NEWLY BOOTED sparc64 IS NETWORKED. The sky's the limit. :-) What I do not understand is how do I know which Module contains which functionality. If I had stuck with the '=m' config I should be able to add a module at boot time. How do I know which module to add? Ken Jones

Ideas? > > Ken Jones Ken, Pulling in xterm, it needs libX11, which, in turn, is pulling in xproto. For the sparc, a masked version of xproto seems to be required. This masking with the "~" is just saying it's in the "testing" set of packages, but it's not hardmasked (it would mention it if it was), meaning it *should* be stable. Regardless, you need the "unstable" version in order to get xterm. There's a number of ways to deal with this, but the suggested way is to add the necessary files, one by one, to /etc/portage/package.unmask. You can do this by adding a line with "x11-proto/xproto ~sparc", or, even better, using the flagedit utility (which you must first "emerge flagedit" to get), and just do: "flagedit x11-proto/xproto +~sparc".

Hi all! Lots of good info... I hadn't stopped to think about a terminal server! OK, lets see about answering some of the questions... - - - - - - Yes, cabling will be fun. The sondes are used for sampling water... The sondes we use are cylinders approximately 2.5 feet in length and about 3 inches in diameter (one, called "big Bertha", is about six inches in diameter) . One end has a data connection that uses a round, screw-on, water tight serial connector, and the business end has several sensors sticking out (optical, chemical, conductivity, a little propeller for mixing water to be sampled, etc., etc.), all within a screw-on cage that protects the sensors from stuff like rocks passing by in the current (fast currents equate to rather large rocks). The idea is to have a tank of water (fish tank, cooler, whatever) fitted with Plexiglas that has multiple holes through which the several sondes are positioned upright, data end pointing up, with a bunch of cables hanging in-place above each sonde - think of the device that sets the bowling pins in place at the end of the alley... Anyway, you place a bunch of sondes into the tank (that has circulating water being maintained at a precise temp, % dissolved Oxygen, and so on), plug each sonde into the cable available directly above it, and then go to the *insert Linux solution here* and initiate communication, data upload, and calibration routines. (By the way, the tank is just about done - its is being debugged as we speak.) After upload and calibration (using the water in the tank), configure each sonde for the next deployment (how often to sample, etc.), turn them off, unscrew the cables and screw on a waterproof cover, remove them from the tank, and place the entire sonde into another protective chamber (6" PVC pipe with holes drilled in a specific pattern and capped on both ends) for another few weeks in some river/lake/coastal location. - - - - - - Yes, I may be confusing myself regarding "I/O device driver" versus "driver" for the sonde... However, I'm pretty sure that all I need is a vanilla "RS232 device driver" that will "just work" for any number of "com" ports by allowing some vanilla terminal emulation package (preferably one that has scripting capabilities) to talk to multiple RS232 ports. I could be wrong about this, in which case I may need to write some code, or perhaps the manufacturer might be thinking of supporting Linux. I don't do the day-to-day instrumentation work, but I am supposed to worry about it none the less. In terms of the "sondes going to sleep", this is based on concerns expressed by the lab along the lines of "if you hook-up the sonde and let it sit too long, you have to start over because it will turn itself off." Also, I use the term "vanilla" a lot because the staff aren't computer types - this has to "just work" like any other tool in the lab. Dear lord - we are talking about biology types after all! ;-) (Unlike engineering/geoscience types!!) - - - - - - So, the other question was about the necessity of having certain signals present. Again, I'm told that the sonde needs all the signals present in a DB-9. I'm guessing this may have more to do with not really knowing for sure and erring on the side of caution, but since there is hardware available that will do this and I can't spend all of my time chasing this down, I'll assume the information I'm getting on this topic is correct. (Biologists not withstanding.) I think this is where the multiport boards or a terminal server would come in... One of the replies mentioned writing a script, and that is what I was thinking about... Specifically, I was wondering if it could be as simple as a script sending the proper bit patterns to get the sonde to do the right things, pipe the serial data through the script and append the data to a file, and s on... (Was that you, John?) - - - - - - - Anyway, I'll have to take a look at the product references mentioned and contemplate what I might need to do in the world of scripting... I haven't heard back from the manufacturer yet, but I'm hoping this will turn out to be a simple project when all is said and done!! Also, I haven't used a terminal server before, so that should be interesting as well. Thanks! If you have any more thoughts, please let me know!! Steve On 5/21/07, Stephen C.

Multiple RS232 Com Ports...
by Stephen C. Daukas 21 May '07

21 May '07

Hi all! I'm wondering if anyone knows how many RS232 devices a "vanilla" Linux kernel can manage simultaneously. I'd like to be able to have up to 32 going at once, with data taken from each device written to its own file via the standard I/O subsystem. As far as I know, wouldn't Linux simply fork the appropriate number of driver threads to read as many RS232 ports as are attached with each device's stream written to a "/dev" file? Why do I want to do this? Glad you asked... I'm investigating an issue at work that involves our instrumentation lab having to upload/download/calibrate multiple sondes and have them ready for field deployment the next day. Currently, we can do three at a time and this takes about 8-9 hours providing everything goes well. The manufacturer's software application claims to supports the simultaneous upload/config of up to 32 sondes. The application will scan "installed" COM ports looking for recognizable sondes, and present those found to the user. Yes - this is a windows solution, so I first began looking for products that would play with Windows... I began looking for hardware solutions (PCI boards, break-out boxes, etc.) on the net and I found a few that will provide 16 DB-9 RS232 ports with full pin-out support as well as so-called "true" interrupt and FIFO support on the host (via their own custom Windows driver, no doubt). And then I started wondering about how to get all of this to work in a Windows environment where "IT" is the only group allowed to install software and otherwise configure a PC for most users whose biggest concern is email... All this got me thinking about avoiding the whole Windows issue and instead thinking about using Linux to take care of the RS232 part, with the newly created files moved to a Windows box (sneakernet to start with), with the normal post-processing of the data taking place as usual in the Windows environment the staff is used to... I'm hoping an "out of the box" distro will be able to handle say 16 RS232 ports and that Linux-based terminal emulation software is available to simultaneously handle those ports as well so I can capture the data using the appropriate protocols... Anyone know of a similar application using RS232 and Linux, or have some thoughts on this? Thanks! Steve

My Ultra sparc64 booted!!
by ken jones 21 May '07

21 May '07

Thank you everybody for your help. My sparc64 finally booted. I used genkernel with the livecd cdrom's kernel 2617 /proc/config.gz. The last piece of the puzzle was getting fstab correct. Here is proof. -----------snip of uname -a ----------------------- kjones-sun2 / # uname -a Linux kjones-sun2 2.6.20-gentoo-r5 #3 SMP Thu May 17 13:58:22 Local time zone must be set--see zic sparc64 sun4u GNU/Linux kjones-sun2 / # -------------end snip-------------- I am not sure whether I learned anything specific to gentoo or to sparc64. I did learn that creating good open source documentation is difficult and that finding one's way through unfamiliar documentation is daunting. Thanks, again. Ken Jones
