With memory-mapped I/O you could just maintain the buffer and have the kernel page it out to disk for you as needed; no need to shuffle stuff around with a background thread. --Andre ____________________________________________________________________________________Building a website is a piece of cake.

You've already had a good bunch of suggestions, but I've got some questions on your hardware. - cpu? - memory - 12gb I know - disk(s) - RAID setup at all? One way to get more performance would be to add another disk or two and to stripe your data between them. This assumes you have enough PCI bus bandwidth available as well. You don't say how you're capturing the light sensor data, but it's obviosly not over a serial port or some other slow device. Network? So if you've got 53 Mbyte/second comming into the system, and another 53Mbytes/second writing out to disk, then you're starting to get close to the 132Mbytes/sec bandwidth of the PCI bus. Finding a motherboard with two or more PCI busses would help. Or something with PCI-E busses. It all depends on your budget and the data acquisition tool you're using. John

By the end of the data acquisition i will end up with the files: data.01, data.02, data.03 ... etc. Each file is a 1GB in size or whatever i set the limit to be.

This helps, but > i run out of space in the buffer before i finish taking data. Hi, Do you mean MB/s as in MegaBytes/second? Lower-case "b" implies "bits" to me, but I suspect you meant bytes. :) Anyway, if you know your total data set is going to exceed your system memory, which will largely get used as page cache, you might as well open the output with O_SYNC and write straight out. Then the big buffer in the writer thread can go away, and you can just queue chunks between the input and writer. A good experiment would be to run the writer thread with dummy input data and see what kind of throughput you get. You could try ext2 (no journalling), or tweaking some of the journalling options in ext3 (data=journal/ordered/writeback, see "man mount"). If you have enough CPU bandwidth, and your input stream has enough redundancy, you could gzip it before writing, which might reduce your output bandwidth requirements. Hope this helps, keep us posted. -Jamie > > Thanks, > -- Brad > > _______________________________________________ > Wlug mailing list > Wlug(a)mail.wlug.org > http://mail.wlug.org/mailman/listinfo/wlug >

Your data set is larger than the page cache, so when you hit the low watermark, it starts write-back. You can deal with this a few different ways, and I'll throw out the easiest ways first: 1) Get more memory 2) Get a faster disk If those are not options, then you can tweak your application by using AIO and O_DIRECT. This will allow you to drive your disk queue depths a bit further and avoid the page cache.

Could you please provide that information? There are a few vm tunables that you could try tweaking, but I really don't think they will help if your data set is larger than memory. We can explore that option, though, if you like. For now, my suggestion is to try using AIO with the open flag O_DIRECT. This will require you to align your data on 512 byte boundaries (and the size of the I/Os has to be a multiple of 512 as well). If you need any help converting your app, feel free to contact me off-list. -Jeff p.s. In your head, is Mb Megabit or Megabyte?

large file performance on linux

by brad noyes

Hello All, I am seeing some really slow performance regarding large files on linux. I write a lot of data points from a light sensor. The stream is about 53 Mb/s and i need to keep this rate for 7 minutes, that's a total of about 22Gb. I can sustain 53Mb/s pretty well until the file grows to over 1Gb or so, then things hit the wall and the writes to the filesystem can't keep up. The writes go from 20ms in duration to 500ms. I assume the filesystem/operating system is caching writes. Do you have any suggestions on how to speed up performance on these writes, filesystem options, kernel options, other strategies, etc? Things I have tried: - I have tried this on a ext3 file system as well as an xfs filesystem with the same result. - I have also tried spooling over several files (a la multiple volumes) but i see no difference in performance. In fact, i think this actually hinders performance a bit. - I keep my own giant memory buffer where all the data is stored and then it is written to disk in a background thread. This helps, but i run out of space in the buffer before i finish taking data. Thanks, -- Brad

SUN Ultra1 booting (still, sorry)

by ken jones

I used genkernel to compile my 2.6.20-gentoo-r5 kernel. After much thrashing I got it to boot. All looked good until the very end when it claimed that it "Failed to set the user font" announced the name of my machine and gave me the login prompt. It would not respond to any keyboard input. After a minute or two it printed a line about "disabled for 5 minutes" and went permanently dead. See below. Any ideas? ---------------snip from almost successful boot--------------- * Starting lo [ !! * Bringing up lo * 127.0.0.1/8 * Adding routes [ ok * 127.0.0.0/8 ... * Initializing random number generator ...

[OT] ethics

Hi Matt. Matt Shields wrote: > I haven't checked out CPSR, so I don't know what they are, but you > can't enforce your beliefs on others. This comes down to personal > choice and where you want to work, or maybe working for the government > is the only available choice at the time. Some people have no problem I agree. What I was suggesting is the possibility for one or more people to make a statement as to where they choose to allow the fruit of their work to go, and/or how it is to be used. That's not about enforcing beliefs, but about sharing (and refining) them. The problem I have with open source licensing as it applies to this discussion I raised is that it does not discriminate as to use. I had once posed the possibility of creating a modified license that would prohibit (any) government from using a certain work, but this is both way too complicated and of course begs the question as to exactly what in a project can be legally restricted in this manner. After all, any project (including the one I am working on now) is comprised of a host of others, all bringing in license terms that do not have such a restriction. Attorneys will be needed to figure out if the idea of a more restrictive version of a GPL is even possible. > working for the government. If you want to change how the government > works because you don't like what they're doing, you elect officials > to change policy and petition those officials to change things. You Well, I think that the effectiveness of the system itself is a whole other debate that would go way off topic here. :) I do find the idea of a national referendum on important issues like blowing up other nations a pretty good idea. Has immediacy. But again, swaying way off here. > don't come up with a society that boycotts working for the government > because there's plenty of other people willing to take the job. There are plenty of people. But, as in organizations like Union of Concerned Scientists (the "concerned", I think, puts the intensity of the overall problem mildly), people have come together and made quite a difference. If they hadn't tried then the issues they raise may well have remained in obscurity while scientists of conscience masked their understanding and "concern" with lots of rolaids. /m

Personally I am more of a hot spare os drive myself, but if you want to use RAID you don't want to be at the mercy of the OS installer Ms, Linux, or otherwise to keep your data safe in the case of an upgrade or reinstall. My philosophy is to keep the OS and data physcailly seperate for ciritical data.

Well, the nice thing I like about Sun hardware is that you have remote serial console access all the way down to the BIOS. This, to me, is a key issue in supporting any critical system. This way I don't have to drive into the data center to fix things if at all possible. Second, in your case you might want to think about a MySQL cluster if you have lots of stringent uptime requirements, but it's not clear what kind of downtime you can handle. You might want to look at the new Sun Opteron X4x000 boxes, they're cheaper and faster than Sparc, but come with the nice remote management features that I find indispensable. Another vendor would be Rackable Computing, they have BIOS access over serial and it works well. Again, not knowing your system loads, I'd say that any AMD Opteron box with plenty of memory would be just fine for you. In this case, the more memory the better, and of course having fast local disks in a RAID setup is also key. Mirroring the OS and data disks is key here to long life. Oh yeah, moving to Solaris in X86 might also help in this transition, in that you get more bang for the buck, but don't have a complete issue with re-training and finding new tools to do what you want. Solaris 10 on x86 is pretty neat. John

MySQL Server Hardware

by joel d

I'll take a stab at this one. At work our MySQL database contains product info and indexing data. The reasoning for designing and taking this outside of the business application is the business app. doesn't do web communication well (limited functionality and at times spotty app reliability). The business app doesn't matter (and I bet no one has heard of it anyway). Our design spec was hearty at a HP DL 385 with dual AMD CPUs (dual core I think) 5GB of RAM and around 7 internal 15k drives in RAID 5. Every bit of hardware is HP/Compaq. Without starting a distro thread we picked Red Hat AS V4. This combo has served us well and I am sure *many* other distros would do this at least as well. For us our biggest corporate reason for R.H. was most of our application vendors suported R.H in one way or another (a vote for getting good at only one skillset/distro). During application & DB development we considered uptime and ordered a second identical box mainly for a total server failure of any sort. They run very well as MySQL master and slave. In the year it has been up we are very happy with this combination. Feel free to forward any specific questions (direct or via the group).

PGP Key Signing Party

by Eric Martin

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 This upcoming meeting we are going to have a PGP Key Signing Party. For those of you who don't know what PGP is, allow me to briefly explain. This is all base off of the GPG Key Signing HOWTO (http://www.rubin.ch/pgp/kspa/gpg-party.en.html) which I suggest for further reading. Those who do know can feel free to skip down to the next paragraph. PGP stands for Pretty Good Privacy, and is a Public Key Infrastructure that allows us to communicate securely and deal with data in a secure fashion. There is a public key that one would typically upload to a server and a private key that you hold on to. With the private key you can decrypt / sign, and with the public key you can encrypt / verify emails and documents. Key signatures come into play when you validate that a specific key belongs to a specific person and extend the web of trust. Here's what needs to be done BEFORE the meeting on your computer, or on a secure terminal (e.g. not in a computer lab on your campus). I'll post directions both for GPG (Gnu Privacy Guard) and Kgpg (the KDE front - -end to gpg for all of those who like GUIs). 1. Generate a Key Pair / Verify your key won't expire soon gpg --gen-key (Default values of DSA/Elgamal is fine and the default of 2048 is good.) I recommend 3 - 5 years for a key lifespan (how long the key will be good for) 1a) for those of you wishing to use Kgpg, goto Keys -> Generate Key Pair and fill in the dialog box Once you create the New key pair, check the Save As box under _Revocation Certificate_ to save a Revocation Certificate (see 2) 1c) For those of you who already have a key, make sure yours isn't about to expire (like mine did). If it has expired, you can extend the life by $ gpg --edit-key <key-id> and typing expire at the command prompt next, generate a new key-pair and sign your new key with your old key so anyone who trusted your old one will trust the new one. 2) Generate a revocation certificate Revocation certificates are for situations where you forget your passphrase, the key becomes comprised, etc you can revoke your key. $ gpg --output revoke.asc --gen-revoke <key-id> Save this in multiple places, print a copy etc in case you need it. 2GUI) If you didn't create a revocation cert in Kgpg, just right click on your new key and select Revoke Key. when the box pops up only check Save As 3) Upload your key to the Designated server for this party (pgp.mit.edu) $ gpg --send-key --keyserver=pgp.mit.edu <key-id> 3GUI) Right Click on the Key, select Export Public Keys, select Default Key Server (make sure it's pgp.mit.edu under Settings) 4) Email me your key's fingerprint so I can add it to the list $ gpg --fingerprint <key-id> Copy and Paste that into an email to the coordinator (me, Eric Martin). 5) print out a copy of that same output and bring it to the meeting. I'll make up a check list and bring them to the meeting for everyone to use. Example output from Step 4: pub 1024D/A9413B9F 2007-04-09 [expires: 2010-04-08] Key fingerprint = D1C4 086E DBB5 C18E 6FDA B215 6A25 7174 A941 3B9F uid Eric J.

I'd like to see Windows do this....

by Tal Cohen

Hi Folks, I recently ran across an interesting situation that I wanted to share this group. A customer of ours called us, letting us know that our server in their data center was beeping. We tried to ssh into the box, but kept getting connection refused. I asked the customer to hook up a monitor and keyboard to the box, and try a simple TTY. Sure enough, he was unable to log in. It turns out that the hard drive that holds the OS (Crux Linux) failed. Now, that in and of itself is not very interesting. What is interesting is that our software kept running even without the OS drive functioning. Our software resides on a separate drive. Since it was already loaded into memory and almost never needs to touch the OS drive, it just kept going.and going..and going.. Tal

3D support

by dulsi＠identicalsoftware.com

I started looking for a new laptop. I'd like one that can play Neverwinter Nights with open source drivers. Obviously that is a problem since 3D support without the binary drivers is not great. I figured since the game is rather old a good cpu (or two for the duo) and a well supported open source driver (I remember hearing Intel having released an open source driver) that it could run reasonably. I asked some linux laptop vendors and everyone told me that I would need the binary drivers. Are they right and we still can't run a 5 year old game? Am I stuck waiting for nouveau?

New ULTRA1 - one step forward, two steps backward....

by ken jones

Folks, When the box failed to boot, you might remember, it complained that the kernel was "too old". I remade the box using the newer kernel 2.6.20. I apparently configured the correct silo.conf (there are five of them in there when using the livecd). It looked like it was going to BOOT!! :-) See below..... Trouble is this is as far as it got. I printed and used as reference the Gentoo Linux 2006.1 SPARC Handbook, the Using UTF08 with Gentoo document and the Gentoo Upgrading Guide. Nevertheless I had a very difficult time with manual configuration of the kernel. I had not the faintest idea which modules I could ignore and which I needed to modularize Question: is there a log somewhere? I did emerge syslog-ng. Another question: Where is the detailed documentation on all the modules? Final question: How do I get a hint at what I did wrong?

Hauppauge 500 woes

by Mike

I've been working on setting up a MythTV box with a Hauppauge 500. The reception I am getting is a bit grainy. I read that it could be the firmware, too high of a signal, or too low of a signal. I took care of the firmware last night by following the directions on their wiki. The picture is still a bit grainy. Before I go out an buy a signal booster I was wondering if anyone had any ideas or experience with the 500. ~Mike -- They who would give up an essential liberty for temporary security, deserve neither liberty or security --Ben Franklin

This will list the OBP tree for you (it's a port of the solaris version of the command). In order for the command to work, though, you need to have the device /dev/openprom. This is an option in the Kernel. So, without having to worry about size limitations, this is not really a critical issue. but if you want to slim the kernel down anyway, compile a larger kernel for now that includes /dev/openprom and then use prtconf to figure out what you need / don't need for your next compile. There is also an eeprom command (/usr/sbin/eeprom) which should provide you with similar info ... Then to save you some more disk space (if you are concerned about that, too), you can gzip -9 your kernel, and SILO will decompress it itself at boot time (just takes a couple extra seconds to boot the box). --Adam > _______________________________________________ > Wlug mailing list > Wlug(a)mail.wlug.org > http://mail.wlug.org/mailman/listinfo/wlug

Re: [Wlug] New ULTRA1 success - almost

by Adam Gomes

Ahhh ... one lovely advantage to Sparc, is that it doesn't have the same silly size limitations that x86 does. So ... _don't_ worry about the size of the kernel. If you have room in memory, it will load. In fat, my own kernel on my Ultra 10 is 3.3MB. That's one reason why there is no "make zImage" for sparc. Of course, a smaller kernel means lower memory utilization, and that of course has its own benefits, but it's not necessary to do all that slimming that is needed for x86. Also, if you want to save some space on your disk, at the cost of a little bit of speed at boot time, you can just gzip -9 your kernel. I did this, myself. The SILO boot loader is smart enough to notice that it is a gzipped image and just decompress it itself. See on my own machine: gomer@callisto:/boot$ ls -l vmlinuz* lrwxrwxrwx 1 root root 20 May 18 2005 vmlinuz -> vmlinuz-2.4.18-sun4u -rw-r--r-- 1 root root 1379575 May 18 2005 vmlinuz-2.4.18-sun4u gomer@callisto:/boot$ file vmlinuz-2.4.18-sun4u vmlinuz-2.4.18-sun4u: gzip compressed data, was "vmlinux", from Unix, max compression gomer@callisto:/boot$ cp vmlinuz-2.4.18-sun4u ~/kernel.gz gomer@callisto:~$ gzip -d kernel.gz gomer@callisto:~$ ls -l kernel -rw-r--r-- 1 gomer gomer 3371524 Apr 15 09:06 kernel gomer@callisto:~$ file kernel kernel: ELF 64-bit MSB executable, SPARC V9, version 1 (SYSV), statically linked, not stripped (not even stripped), lol. So, please, don't lose any sleep over the size of your Kernel ... not on Sparc64 at least. --Adam On Fri, 2007-04-13 at 17:51 -0400, Eric Martin wrote: > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA1 > > I realize I may need to qualify my last post. by 'Make as many modules > as possible' I meant what Mike said.

I built a no-module kernel using all the hardware I knew I had and gzipped it, it ended up being a tad over 1 MB for my Ultra 2-specific 2.4.34, and had no problem firing up from SILO. Dmesg will give (the OP) a pretty good idea of what the generic kernel is seeing. Brian J. Conway

Yes, there is parking on both the quad (front of the building) and street (back of the building). There shouldn't be too many problems getting a spot at that hour, I believe.

REMINDER: Upcoming WLUG Meeting

by Andy Stewart

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 HI Everybody, We have a WLUG meeting coming up on Wednesday, April 11th, at 7:00 PM in the Access Grid room on the WPI campus in Worcester, MA USA. At this meeting, Andy Stewart will give a presentation on his recent work with the Delcom USB I/O Development Board. Part of this work involves writing a Linux kernel device driver for the board, which will be discussed in some detail. This is my first attempt at writing a Linux device driver. The hardware is exposed to the user via sysfs. Reference usbled.c to get an idea of how this driver is coded. Another part of this work involves hardware add-ons such as an I2C memory chip and a character LCD display, both of which will be demonstrated at the meeting. Yes, we'll see some blinking LEDs, too! Afterwards, we'll talk about the May meeting, and my hope that we can have a PGP key signing party at that meeting. I'm looking for a volunteer or two to run the May meeting, since I don't know how to properly run a PGP key signing. Besides that, I'm hoping to get my passport back from the US Govt. before that meeting (it is being renewed). I'll bring these books for the free raffle: - The Ruby Way - 2nd Edition, Addison-Wesley - Java in a Nutshell, O'Reilly (used) - User Mode Linux, Prentice Hall We should also talk about this summer's WLUG party/BBQ. If there is anybody who lives nearby that would like to host the party, please let me know. (BTW, what ever happened to the pictures from last year?) We'll then adjourn to the Tech Pizza restaurant for food, drink, and good conversation.

I wouldn't expect this for a HID device, but since the event* nodes aren't showing anything, who knows...

HI Tim, Thanks for the tip about libusb. I have lsusb installed, and I also have usbview. I'm surprised that I can't find the proper thing to "cat" to see output from the barcode reader.

Re: [Wlug] Seeking help with a USB barcode scanner

by Tim Keller

This is what I would do. 1. Install "lsusb". It behaves much like lspci so you can what devices are on your system. When you do a "lsusb" it'll list what devices are hanging off of each USB bus. Do a before and after so you can see the major/minor numbers. 2. When you know the devices major and minor number you can write a program using libusb that'll look for the device, open the device if it exists, take posession of it and then read data to and from it, hopefully. http://libusb.sourceforge.net/doc/examples-code.html Looking at that example, I don't think it would be too hard to whip up a program to open the device and then loop until there's input and then dump it on the screen.

I haven't heard of a FAT64 yet, but NTFS can support files up to 1 exabyte (1x10^6 terabytes). (Or was that exbibyte...?) -- Aaron Haviland

Did you install them yourself, or call for help? Where did you get them? Do they come in different kinds, or can I get an ADLS splitter and know I have one? Why did you need more than one (as implied by your use of plural)? I think my ISP wants to add one outside the house next to the NID (box with terminals to screw the phone lines to). I don't even think there is one on this old house. I assume that then there must be new holes drilled in the outside wall of the house to run the digital cable alongside the voice/analog wires into the house. I don't see why the splitter can not go a few feet farther down the wire, inside the house. Less drilling, no rain on the splitter, the only downside seems to be about ten feet of the old wire stays there, but is that worse than what comes off the telephone pole? -- Keith

As I understand it, switches are much simpler and more basic than routers. If it has QoS, I think it's either a router or a managed switch. My GigE router is a D-Link DGS-105, and it has no administration whatsoever; you just plug your cables into it and go.

Gigabit NICs for Linux

by sageman＠WPI.EDU

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

-----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!

He's not worried about security, he just doesn't want his mother to see those pictures of him mooning the camera. I suppose we can trust the cameraman to use the pictures only as you ask. I was thinking of putting some low-res, but recognizable faces on the WLUG web site, to help us (i.e. me) to remember names. The key signing just made me think of it, but had nothing really to do with the plan. I am not sure why anyone would object to that unless it has something to do with the witness protection program, or running from the law. But I have neither camera nor write access to the web site, so it is not for me to say. -- Keith

The only devices that would have access to the statistics he is talking about are your DSL modem and the DSLAM. If your modem doesn't provide the statistics, then there is no way to get them directly unless you had a hardware DSL analyzer to hook up to the line.

It's possible some of that information is available on the internal interface via SNMP, but I haven't frequently seen that on consumer-grade devices. I haven't used DSL in a long while, but I know that that vast majority of cable modems have a status web page on the internal interface at http://192.168.100.1 that gives you upstream and downstream power levels, downstream SNR, frequencies used, and occasionally provisioned rates. (On most well-configured firewalls, that also means remembering to allow 192.168.100.1:80 in on the external interface, heh.) If you hunt around for your DSL modem model in your search engine of choice, there may be something similar. Either way, I imagine a truck roll will still be your best course of action. Brian J.

DSL testing

by Keith Wright

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.

GPS on Linux

by Richard Klein

Andy, I think you were talking about using a GPS receiver with Linux after the last meeting. The receiver I had mentioned came in a couple days ago. It's a Navibe SP611 (http://www.geeks.com/details.asp?InvtId=NAVIBE-ORN) and it does indeed output NMEA 0183. The Navibe website is easy enough to find (http://www.navibe.com/) but it doesn't even acknowledge the existence of the SP611. Linux seems to recognize the serial/USB bridge in the GPS as a Prolific PL-2303: dmesg says: usb 2-1: new full speed USB device using uhci_hcd and address 3 pl2303 2-1:1.0: pl2303 converter detected usb 2-1: pl2303 converter now attached to ttyUSB0 But I can't get GPSMan or GPSDrive to recognize it. "cat /dev/ttyUSB0" gets no response, and I have to hit CTRL-C to get the command prompt back. Per this page (http://koti.mbnet.fi/lonnberg/pl2303x.html) I found that bMaxPacketSize0 = 64, which suggests the bridge is a PL-2303X rather than a plain vanilla PL-2303. Apparently this used to require a patch, but only up to kernel 2.6.8. uname -r says I'm at 2.6.15-1-686, so this shouldn't be an issue. What should I try now? Oh, the GPS receiver did send a stream of NMEA data to my Windows computer at work with GPSDiag, so the reciever doesn't seem to be defective. -- Rich

Well, it was a while ago... ...in a nutshell, I was rebuilding base system and the portage tree a few months after install, following instructions posted and detailed reasoning explained by a senior Gentoo developer. After a few problems problems, the error that blocked me from fixing anything else was that the rsync server I chose at install time was no longer valid, which I verified by looking at the list again. But no one seemed to know how to change it, and I just couldn't deal with re-installing the whole thing at that time (I did a Stage 2, which took 2 days). I still have Gentoo installed on that computer, but I just don't have time to deal with it right now. Maybe in the summer, then again, maybe not. Slackware may be more appropriate, considering time constraints.

Re: [Wlug] Progress with new Sparc????

Ken, I'm still a little confused. Are you trying to boot an already installed OS, or are you trying to boot from cd? If the former is true, what does the partition table on the drive look like? BTW, the sun serial console should work at 9600/8/n/1 on a null modem cable connected to your PC's serial port (or even an old vt100 terminal). Can you share with me the output of probe-scsi? If you get me a little more info, I can probably help you out. Like I said, I run linux on sparc at home (and have for years), and I used to be a sparc / solaris system admin a few years back.

Doug et al I found my cross over cables. printenv told me to set up at 9600bps ASCI 8 none 1. I have tried VT100 and auto-detect. When I turn on the sparc it tells me that it is using ttya for input. However, my hyperterminal sees nothing. If I slow down the expected clock rate to 2400 I get to letters "pp" when I startup the sparc. I do not get "ok" and I get no response when I hit the "Enter" key. Too bad, since that connection would allow me to show you what my terminal is saying. I did get a good response from probe-scsi and probe-scsi-all. It saw both hard drives. I am now trying test-all. Last time it just hung but now it seems to be correctly testing the terminal screen. OKAY! I know something. Self test failed a Transceiver check. It says: Transceiver check -- failed Selftest Failed. Return Code = -1 Testing sbus@1f, 0/SUNW, fas@e 8800000 CE DMA fill from address ffef8000 for 80 bytes Testing sbus@1f, 0/SUNW fdtwo@f, 1400000 Testing floppy disk system. A formatted disk should be in the drive. No diskette or incorrect format. Self test failed. Return code = -1 I wondered what is the "transceiver test" which is failing. The word "transceiver" usually is referring to I/O. I was correct. I installed the ethernet cable and the transceiver test passed. I know one thing now. The CDROM reader does not work. Part of test-all is to check for a formatted disk in the reader. I put a known good disk in, but the SUN does not see it. That does not explain why it will not boot up correctly. It should note that there is no disk and boot to installed linux. My latest status is to try booting over my office network. I gave my home router/DHCP server the new sparc's ethernet address and assigned an IP address. I have no idea whether the sparc is configured to expect a DHCP address. I do not see where I can configure that.

Re: [Wlug] Suse Linux Professional 10?

by Clint Moyer

I could not get Compiz to work on OpenSuSe 10.2. Besides I can't advocate for Novell considering their recent partnership with MS. Any of the Ubuntus are great. The GUI frontend to apt works exceptionally well. After you've updated the list of repositories, adding pretty much any app is a simple point-n-click. It was pretty straightforward to load Nvidia's driver and setup Beryl. Sweet eye candy! In 13 years of using Linux, it's the first distro I've considered user-friendly enough to put on my kids' PC. If you want to be cutting edge, Ubuntu 7.4 officially releases next month. Of course, you can also get it right now.

>From a neophyte's point of view, I'm pleased with oSuSE 10.2. I also installed using a DVD, but can't say it went without a hitch. The only problem was getting my USB wireless adapter to work. But I had already had that problem with Ubuntu and Gentoo. I never did get it to work directly (ended up using a NIC and a Buffalo wireless converter). But in the course of trying those three distros I decided I liked the oSuSE best...and I think it was YaST that tilted the scales. Again, I was a blank slate 3 months ago so I can't give you a "compare and contrast" with previous releases of oSuSE or YaST.

Re: [Wlug] Suse Linux Professional 10?

by James Gray

I've had a very good experience with Ubuntu. I can't really compare it to anything else, because it is the only distro that I've ever used for very long. As you know, Ubuntu/Kubundu decision is based on your preference for Gnome/KDE respectively. The desktop CDs for both of these distros can boot right from the CD into a fully functional system. I recommend you burn a CD and take it for a test drive. James On 3/20/07, douglas.r.aker(a)verizon.com <douglas.r.aker(a)verizon.com> wrote: > > > OK, did so more research.

by Robert L Krawitz

From: douglas.r.aker(a)verizon.com Date: Tue, 20 Mar 2007 14:33:42 -0400 OK, did so more research. Looks like it's called OpenSuse 10.2. Read some reviews. Some good, some not so good. Short answer: after a rocky start, this release is really, really good. I found the *initial* upgrade from 10.0 to 10.2 to be very painful -- the upgrade process was actually the most painful I've had, and I've been using SUSE distributions since ~6.0 (usually I take every second or third release). The problem was that the RPM consistency checker was finding a problem, but gave an empty list of inconsistencies, so I couldn't resolve it except by cut and try. The YAST online update is also ugly -- it only wants to upgrade from a site that it picks, and doesn't let you easily upgrade from your own mirror. The one major other problem I had, when upgrading my server, is that I had to rebuild my cyrus imapd databases, and this took a bunch of web searching. The other major annoyance is that 10.2 doesn't support apt. That's the bad. When I eventually got past this, I've found it to be really good. Laptop support is particularly improved; suspend to disk is considerably faster, suspend to RAM even sometimes works (it's actually the resume that's the problem, and it's the usual graphics thing), power management in general works well, and Network Manager does a really good job of managing network interfaces on a laptop (you don't have to use it -- you can use the traditional if-up tool if you like, but once you try Network Manager on a laptop you won't want to go back). I think they've finally stabilized their software installation -- 10.1 was reputed to be a real horror story. There are a lot of smart (Novell's apt-like tool -- why they couldn't just use apt is beyond me, but smart can handle a lot of different repository types) repositories around. The packman and guru repositories have a lot of good stuff; I also use this to do my upgrades. KDE 3.5.6 finally fixes a raft of problems, and if you sync to a hand held make certain to upgrade to 3.5.6 before trying to sync, or you'll basically lose all of your calendar appointments. I'm finding I'm having to build a lot fewer things myself than I did with 9.1 and 10.0. I've largely depopulated my /usr/local. -- Robert Krawitz <rlk(a)alum.mit.edu> Tall Clubs International -- http://www.tall.org/ or 1-888-IM-TALL-2 Member of the League for Programming Freedom -- mail lpf(a)uunet.uu.net Project lead for Gutenprint -- http://gimp-print.sourceforge.net "Linux doesn't dictate how I work, I dictate how Linux works." --Eric Crampton

Not all of YaST is effected, but the part having to do with software installation and package management was definitely screwed up. It was so bad that version 10.1 was re-released to fix these problems. However, before the re-release, I had switched from YaST to the Smart package manager (http://labix.org/smart) It is available on the SuSE media, if I recall correctly. I use the Smart PM for software installation, and I use the other parts of YaST accordingly. Its not an ideal solution but it functions. Once Microsoft got involved with Novell, I began to have reservations about my continued use of SuSE. I still have SuSE 10.1 on my server at home, but my new laptop is running Kubuntu and I'm very pleased with it. I use the Smart PM on Kubuntu, too! The perception of greener grass is relative - perhaps it is better stated that the brown patches are in different places. :-) I currently have no plans to upgrade my SuSE installation due to Microsoft's involvement with Novell. Once I start to feel like my server is running outdated software, I'll look at alternatives at that time, but that'll be a while from now.

Yes. I hear nothing but awful awful things about Suse 10.0 and 10.1, especially in regards to Yast. 10.2 claims to have pulled it out of the fire, and people say Yast is improved. However, you don't have to stick with Yast....SMART is making headlines lately as the next end-all be-all package manager.

Ok, I'm a tony bit confused. Have you installed the OS on the drives, and are now booting the OS for the first time from disk, or do you get these messages when you are booting from CD? If sda is a hard disk, how is it partitioned? Did you use a sun disk label, or some other set of partitions / file systems?

I found this website, but perhaps you've already been here: http://www.gentoo.org/doc/en/handbook/handbook-sparc.xml I also recall that SuSE Linux had a version for Sparc a long time ago. I've used it. I think it was version 7.x but I'm not sure. Perhaps you can still get this CD. > > No. But carry on.

My memory is very vague since its been a long time since I've done this. Here's another URL which may help: http://www.linux.com/howtos/SPARC-HOWTO-12.shtml One last thing. I did a quick Google and found this tidbit about properly burning the CD. Perhaps it will be helpful. http://lists.suse.com/archives/suse-sparc/2001-Mar/0146.html I'm sorry that I couldn't have been more help, but hopefully these will point you in the right direction. Good luck, and keep us posted.

Re: [Wlug] posting rules request

by Andy Stewart

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 HI Mark, I'm cc'ing the list so folks will know what I've been doing behind the scenes when I receive requests like this. I don't personally mind if folks put relevant, local Linux job postings on the list, as long as it doesn't get out of hand. Having the courtesy to ask first (as you did: thank you!) goes a long way, in my opinion. I agree with Keith - definitely no advertising allowed. Your job posting was fine in this regard - it clearly wasn't an ad for your company or its products. I try to put "JOB:" in the subject of the post, so people can filter it accordingly. Good luck finding a candidate who meets your needs, and thanks again for asking prior to your post.

From what I have seen, job offers are welcome if they are local.

Is there a ROM setup program that you can get into before booting? Is it set up? For the right boot device? -- Keith
