Subject: [RndTbl] MUUG Meeting, March 9, 7:30pm -- Marvell SheevaPlug
Message-ID: <201003021734.o22HYuQ02500@iron.cs.umanitoba.ca>

The Manitoba UNIX User Group (MUUG) will be holding its next monthly
meeting on Tuesday, March 9.  The meeting topic for this month is
as follows:

   Marvell SheevaPlug

   This month, Kevin McGregor will be presenting a "show and tell"
   of the Marvell SheevaPlug, a Linux-based computer which fits in a
   power adapter.  With  a  1.2 GHz ARM CPU, RAM, flash memory, gigabit
   Ethernet, USB and more, all at under 7 watts, this small device has
   enormous  possibilities!  Kevin will talk about his particular
   experience with the SheevaPlug and his planned use for it.

   Before the break, as this month's RTFM topic, Samuel Pauls will be
   covering the vim(1) command.

The group holds its general meetings at 7:30pm on the second Tuesday of
every month from September to June.  (There are no meetings in July and
August.) Meetings are open to the general public; you don't have to be a
MUUG member to attend.

   **********************************************************************
   Please note our meeting location: The IBM offices, at 400 Ellice Ave.
   (between Edmonton and Kennedy). When you arrive, you will have to
   sign in at the reception desk, and then wait for someone to take you
   (in groups) to the meeting room. Please try to arrive by about 7:15pm, 
   so the meeting can start promptly at 7:30pm. Don't be late, or you may

	I downloaded it and tried it in a VM. I've got to the point where 
(after installation) it boots. At that point it comes back and presents 
a boot menu. FreeBSD and PXE are the only options. Neither produce 
anything meaningful. FreeBSD just says it can't find something and PXE 
won't find something from the net (obviously).

Message-ID: <6756caf11003061151j5f624dchd3c3932246a1f5aa@mail.gmail.com>

Sorry for the off-topic post, but I hope someone on this list can help me.

I have a PCIe card which has a capacitor on it which I'd like to remove and
re-install, but on the other side of the board -- it's in the way of
something, and if the cap isn't moved, I can't use the board. It's not
surface-mount, and the leads go right through the board so it should be
possible. I tried unsoldering it myself, but my soldering iron wasn't hot
enough... or something. I'm not experienced with soldering. I may have even
damaged the cap, for all I know, so I may have to get a new one. It's
cylindrical and appears to be 330pF, 16V. I have pictures, but I'm not sure
if the Roundtable list allows attachments (I expect not). I can email them
directly to any interested party.

If any of you can help, please let me know!

Thanks,
Kevin

The iron isn't hot enough. The pad is probably conducting the heat away 
too quickly. A hotter iron is in order. Desoldering usually takes a hotter 
iron and some solder wicking material to prevent component damage.

Depending on the board you will require long leads on the part when moved 
the other side of the board because you will likely have to solder 
underneath the part, ie; between it and the board. There may not be 
sufficient pad, on the side the part was originally on, to solder to even 
though the leads will come through there.

If you must solder underneath the part try to put a clip lead on the 
component lead, or something similiar, between the component and the tip 
of your iron.

On behalf of the 5th International Workshop on Systems Software
Verification (SSV '10) program committee, we'd like to invite you to
contribute papers that focus on finding real, applicable solutions to
systems software verification problems. Paper registration and abstracts
are due Friday, May 28, 2010, 11:59 p.m. Samoan time (UTC-11).

Industrial-strength software analysis and verification has advanced in
recent years through the introduction of model checking, automated and
interactive theorem proving, and static analysis techniques, as well as
correctness by design, correctness by contract, and model-driven
development. However, many techniques are working under restrictive
assumptions that are invalidated by complex embedded systems software
such as operating system kernels, low-level device drivers, or
microcontroller code.

The aim of this workshop is to bring together researchers and developers
from both academia and industry who are facing real software and real
problems with the goal of finding real, applicable solutions. By "real"
we mean problems such as time-to-market or reliability that the industry
is facing. A real solution is one that is applicable to the problem in
industry and not one that only applies to an abstract, academic, toy
version of it. In this workshop we will discuss software analysis and
development techniques and tools; this forum will serve as a platform to
discuss open problems and future challenges in dealing with existing and
upcoming systems-level code.

Topics include but are not limited to:

* Model checking
* Automated and interactive theorem proving
* Static analysis
* Automated testing
* Model-driven development
* Embedded systems development
* Programming languages
* Verifying compilers
* Software certification
* Software tools
* Experience reports

Paper registration and abstracts are due Friday, May 28, 2010, 11:59
p.m. Samoan time (UTC-11).

For more details on the submission process, please see the complete
Call for Papers at:

SSV '10 will be held immediately following the 9th USENIX Symposium on
Operating Systems Design and Implementation (OSDI '10), which will take
place October 4-6, 2010.

We look forward to receiving your submissions!

Subject: [RndTbl] RAID controller trouble
Message-ID: <000001cac35a$45035640$02344c18@wp.shawcable.net>

I have a client having trouble with her RAID controller. She reports that
she keeps getting an error on boot that her raid set is out of
synchronization. It takes close to an hour just to boot when this happens.
When I've looked at it the problem did not occur, but this can happen with
intermittent problems. I ran hard drive diagnostics, CPU, motherboard, RAM,
and everything works fine. I have a hard drive controller diagnostic from
Seagate, but it isn't designed for RAID. Her motherboard is an Asus K8V, I
think it's K8V-MX, she has 2 SATA hard drives mirrored, and she runs Windows
XP. I have mentioned that she may have to replace her motherboard, but I
don't want to tell her she has to do this unless I can confirm it is
necessary. If she replaced the motherboard and the problem continues, I
would hear about it!

Thanks,
Rob Dyck

You didn't mention what RAID controller.  I assume some sort of
onboard, like Intel MATRIX?

This can happen if her comp resets/crashes or shuts off abnormally.
The real issue may be diagnosing that, not the after-effect of the raid
rebuild.

Hmm, in XP with Matrix RAID (I don't use any other ob ones) I see
reasonable boot times (maybe 40% slowdown max) even when in rebuild
mode.  Only in Vista do I see horrendous boot times during rebuild.

First thing to do when having weird mobo issues is look for bad caps
(even slightly puffy with no goo == bad caps).  See my site:
http://www.tecnopolis.ca/tecnopolis/leakycaps.html
I fix bad cap mobos.

According to the ASUS website that motherboard has VIA VT8237R southbridge.

I did visually examine the caps the last two times she called me about this.
I didn't see any bulging caps. I worked as PC technician at a retail store
from October 2008 through November 2009. We all have to do grunt jobs
sometimes. I was a computer programmer or systems admin since February 1981,
but when you're unemployed you take what you can get. I saw more damaged
computers each week at that job than I had previously seen in my life. The
manager didn't like us to replace bad caps, because that might not fix it
and customers at a retail store got pissed off at even slightly high bills.
The point is I have seen enough bulging capacitors now to recognise them.

I have so many diagnostic programs now that I can pin-point just about
anything. But nothing for RAID. Is there any RAID diagnostic out there?

Thanks for the tip about RAID rebuild times. I haven't used RAID myself on a
PC. Slowly puttering away with a server at home, but that's a new install
and I'm trying to make it minimal. I have no way of knowing how long a RAID
resync is supposed to take. She has 2 drives shadowed.

I did ask her about shutdown procedures, and she did claim she always shuts
down properly. She's been using computers long enough that she should know
that. But then again I'm reminded of a customer I wrote a system for in the
mid 1980s. She complained about database damage. She also claimed she always
shutdown the application properly. Back then Windows didn't buffer writes,
so all she had to do was exit the application then shut off the power. After
repairing the database by hand 3 times, I "updated" her application to flush
all write buffers after each transaction. I did warn both her and the
manager who hired me that this would slow the application somewhat, but
after having to repair the database 3 times it was necessary. The database
damage mysteriously went away after that change.

Before I start making nasty accusations, is it possible her mobo RAID
controller isn't flushing during the Windows shutdown procedure?

	Dumb thought... If the problem is the onboard RAID controller... 
Wouldn't it be cheaper for your client to get a RAID card instead of 
replacing the motherboard? There were a number of suggestions last year 
and the year before detailing which ones would be best. Of course there 
are implications I haven't even thought of since I've never been able to 
get a RAID system working let alone administered one.

I'm curious, was the bad caps issue widespread when you were in that
job?  Any trends you noticed in brand, year, etc?  I certainly am
noticing trends (like the badcaps issue did not stop in 2003) and would
love to hear someone else's experiences in the field.

If you're using the ob VIA raid then there really is no "raid
controller" as we know it.  As with (mostly) all ob raid, it's just
some firmware bits and bios tweaks to make the system raid capable.
There really is no "raid controller" to test.  The "controller" is
really the main CPU.  So, no, you won't find any diag tools.

Now, there will be HD diag tools you can use to test just the HD's, but
generally you have to somehow disable the RAID first (risky as when you
re-enable, there's a question of it knowing the array is still there!),
or take the drives out onto another system (1 at a time) to test.

If she isn't reporting any crashing/rebooting, and the RAID is always
degrading, then the problem is almost invariably hard drives dying.
Run full scan diags on them.  Even with zero errors, drives can kick
from arrays.  I see a lot of this lately, esp with Seagate drives (what
I sell most of).  Perhaps the HD vendors are making their non-raid
drives more raid-unfriendly to push the raid-version drives, which are
now relatively exorbitantly priced?  :-)

Good raid systems (like linux md raid) will take a LONG time to rebuild
when the system is busy (so it won't bog down your system).  Windows
fake raid drivers sometimes make the mistake of rebuilding too fast and
result in horrible interactive performance for the duration.

Nearly impossible, though in the past I have seen some incredibly
braindead VIA southbridge behavior.

Hear hear!  Considering ECC RAM sticks cost just a small fraction more
to make than non-ECC, and same with mobos(/cpus) that support ECC, why
everything isn't ECC is beyond me.  If everything was ECC, economies of
scale would kick in and the additional cost would be negligible.
Consider back in the 440BX days every board supported ECC, it boggles
the mind as to why today you must buy server/workstation (and I mean
$300 a mobo workstation) class equipment to get ECC.  The 975 was the
last "mainstream" (albeit "extreme enthusiast mainstream") Intel chipset
with ECC.  AMD fares no better.  WTF??

2 of my 3 systems are ECC, and the 3rd is mostly just used for games.

Ha!  As per above, no Intel/AMD desktop boards have ECC.  It's sad.

It's not the RAM that's the issue, it's finding a mobo to run it.  And
I trust Kingston implicitly.  I have sold nothing but Kingston RAM
since 2001.  We're talking thousands of sticks here.  I've had only
about 5 RMA's in that time, and those probably due to static
discharge.

I would never sell no-name sticks again.  Beware the peddlers of "name
brand" RAM where they are claiming the name of the DRAM manufacturer is
the name brand of the stick.  Those are crap no-name sticks.  "Name
brand" means Kingston, or OCZ, or Corsair, or similar actual branded
stick (not back-of-truck leftovers from China).

Don't attribute flash quality to DRAM quality.  Most flash, including
Kingston's carries only a short (1 year) warranty and is a completely
different beast than DRAM.  That said, I've sold (and used) a number of
Kingston flash without issues.  YMMV.

counterfeit parts through my distro channels.  Since I service all I
sell, I would know if drives were gray-market/non-RMAable.  If you want
guaranteed product at in general better prices than Primex^H^H^H^H^H^H
CBIT, let me know.

Ah, that reminds me of the bad ol' days when the guys at Primex were in
the back room putting NEC stickers on no-name TW crap CRT's...

March 9, 2010: Marvell SheevaPlug
This month, Kevin McGregor presented a "show and tell" of the Marvell 
SheevaPlug, a Linux-based computer which fits in a power adapter. With a 
1.2 GHz ARM CPU, RAM, flash memory, gigabit Ethernet, USB and more, all 
at under 7 watts, this small device has enormous possibilities! Kevin 
talked about his particular experience with the SheevaPlug and his 
planned use for it.

Thanks

I didn't notice a trend in brand, they all appeared to have issues. I did
notice that leaking caps caused the motherboard to completely fail; bulging
caps caused strange behaviour rather than complete failure, but it was in
the processing of dying quickly. Motherboards older than 2003 did have more
problems than newer ones, but the new ones also had bad caps.

There was a strong trend with LCD monitors. We got a number of monitors in
for repair, but were not able to repair most of them. The usual problem was
blown caps on the power supply. This occurred with Dell, Gateway, and NEC
monitors. Most of the monitors brought in were Dell. An occasional monitor
had a cracked display; you can't fault the manufacturer if someone sits on a
monitor. We couldn't swap parts because they all had the same problem: blown
caps in the power supply. I noticed all monitors with this problem had an
LCD display manufactured by HannStar. The monitors have 3 parts: LCD
display, power supply, and signal processing board. The two boards are not
made by HannStar, so you can't fault HannStar, but the power supplies are
crap.

I had a bit of a problem there. The owner wanted a technician who was able
to repair LCD monitors, but the service department foreman did not want
anyone to do so. So I was stuck between the owner and department foreman. I
did replace power supply capacitors for one monitor, but as soon as power
was applied the replacement caps blew as well. I had checked voltages, and
they were correct briefly but kept dropping out. Voltage would be Ok for a
fraction of a second, then drop, then come back. I thought replacing the
caps would fix it, but whatever blew the caps in the first place burnt out
the used replacements as well. Possibly a bad voltage regulator.

One customer had blown capacitors for his onboard motherboard audio. He
wanted to connect sound from his computer to his stereo. Unfortunately he
connected line out from his computer to line out for his stereo. He said as
soon as he connected it, he heard a pop. Sound on his computer hadn't worked
since. I opened the case while he was still at the counter; yup, 2 blown
caps. I told him we could replace the caps but the surge may have damaged
circuitry on his motherboard, and the service department foreman doesn't
like us to replace caps, so recommended a new motherboard. Besides, that
store charges $30/hour for normal desktop service work, but $60/hour for
soldering work. It would cost him less to replace the motherboard.
Unfortunately the foreman convinced him to buy a used computer. If he just
replaced his motherboard he would have had a brand new motherboard and all
the stuff he had before. The used computer cost more than a new motherboard,
and was older than his computer. The customer's father said he knows how to
solder so may replace the caps himself. I cautioned him that he has to
replace the caps with an exact match for capacitance and voltage, as well as
dielectric vs. ceramic, and has to be careful when soldering a multi-layer
board. Don't overheat the board, you can burn it easily.

The guys talked about bad power supplies in Antec cases, but I thought Antec
were premium cases. The computer I have at home has an Antec case, and I've
never had problems with it. The Antec cases we got through recycling while I
was there worked fine, their power supplies could be used as replacements
for customer power supplies. Some technicians also talked about AMD
processors not lasting, but again I didn't see that. Again, my computer at
home uses an AMD K7 Athalon Thunderbird processor. I've never had problems;
but then I was cautioned when I got it that AMD processors require good
cooling. I got a very good CPU heat sink. The only problem I've had with my
home computer was the video card. I got an G-Force3 v8200 when it was brand
new, top-of-the-line. The board died, but the retail store I worked for had
an exact match as a used card. I bought the used one at employee discount.
When I got home I found the used card had a seized GPU fan, but my old card
had a working fan. So I "Frankensteined" it together: took the working fan
from the dead card. I now have a program to monitor sensors, the GPU is
running hottest of all. I guess that's why that's the component that failed.
As for computers through the store: most computers had Intel CPU chips, but
that was due to volume of sales. I didn't see any trend with repairs: Intel
vs AMD.

That store sells 2 brand of hard drives: Western Digital and Seagate. The
Western Digital drives last perfectly for 3 years, but can fail after that.
Seagate drives are 50% more expensive, but more reliable.

Maxtor had manufactured hard drives, but were bought out by Seagate. In
their last days they replaced the metal top of their hard drives with a
heavy foil. The foil top drives failed a lot. IBM Deskstar hard drives also
had a reputation for failing, and I did see a number of them come in. Some
technicians called them "IBM Deathstar".

Hmm, the sites do seem to suggest it does ECC.  Though I've learned in
the past that sometimes even sites/manuals/bios's that say ECC, do not
do ECC!

If it does do ECC, perhaps it is because these are AMD chipsets, and
not NV or ATI.  That would make sense as the real AMD ones are usually
better.  Most of the AMD-compatible mobos you see these days are NV or
ATI.

So perhaps there is a cheap(er) way to get ECC than Intel-based
workstation boards.  However, based on past experience I'd be loathe to
switch to AMD from Intel.  No flame war here, just cold hard experience
selling these things for 11 years.  If AMD is still giving cheap ECC,
seems to me that Intel is royally screwing up by not providing
something that can compete.

Hello,

Looking for a recommendation of a NAS box that I can install my own Linux
distro on. (i.e. not a proprietary firmware based NAS). I'll probably
install either CentOS or UbuntuServer on it.
I would like it to have two or three hot swap bays.

It doesn't have to be an all-in-one solution, even just a decent case/MoBo
combo you have used would be fine.
Does that make sense?

LJ has ads from Polywell every month, I'm pretty sure they have something up your alley.  (www.polywell.com/us/lx)
You could also use the BeagleBoard, buy a 2-disk SATA hotswap tray, and a chassis, but you can't use a standard distro.
You could always rig up to eSATA enclosures to pretty much anything that supports eSATA... Or USB, albeit at lower performance.
The two-hotswap-bay requirement will likely have you either using external equipment, or an ordinary ATX mid-tower case... Regular 5.25" bays also get you reasonably cheap hotswap trays.
Size-wise, almost no-one bothers making OEM product at the 2-disk level; there's tons of options in 19" units or 8-bay towers.
How much are you willing to spend?

OK, I've come to the conclusion that I'm doing something wrong, but can't
for the life of me figure out what it is. Going over and over and over
documentation, I must be interpreting something wrong, because I think I'm
doing what it says.

 

I'm setting up a new box with CentOS. Installed MySQL, and it's running. Now
I get to setting the password. Here's the issue.

 

I start with: 

mysqladmin -u root password SQLROOTPASSWD.

 No problem

 

Then I try:

mysqladmin -h myserver.mydomain.com -u root password SQLROOTPASSWD. 

 

This is where things go South. I get the response 

mysqladmin: connect to server at '(my server)'  failed

"Access denied for user 'root'@'192.168.1.160' (using password: NO)'

 

I'm at a loss. Hours of fighting with this, and I'm nowhere... Help?

use -p or --password

"mysqladmin ... password foo" sets the password, to give a previously
set password, just do "mysqladmin -h myserver.mydomain.com -u root -p"
to be prompted for it. Or to give it on the command line
--password=SQLROOTPASSWD/-pSQLROOTPASSWD.

Your problem is that MySQL stores permissions based not only on users, 
but also where they're coming from.

Try in the mysql console "grant all privileges on *.* to 
'root'@'192.168.1.160' IDENTIFIED BY '<yourpasswordhere'" followed by a 
flush privileges.

All the best,
Robert

The default for mysql clients is to connect with no password. Your
first command connects with no password, and sends commands to change
the password. Don't confuse the parameters you're sending with the
ones you're supposed to send to connect with a password.

To connect with a password, pass "-p" on the command line to have the
client prompt for the password, or do the longopt
"--password=MYPASSWORD"

eg

$ mysqladmin -u root -p somecommand somearg
Enter password:

or

$ mysqladmin -u root --password='abc123' somecommand somearg

Subject: HotCloud '10 Submission Deadline Approaching
Date: Thu, 18 Mar 2010 09:16:00 -0700
From: Lionel Garth Jones <lgj at usenix.org>

We're writing to remind you that submission deadline for the 2nd USENIX
Workshop on Hot Topics in Cloud Computing (HotCloud '10) program
committee is approaching.

Please submit your work by Tuesday, March 23, 2010.
http://www.usenix.org/hotcloud10/cfpb

Cloud computing has attracted a great deal of attention both from the
research community and from industry. The cloud computing paradigm has
evolved over the years from a basic IT infrastructure (data centers) to
platform as a service (PaaS), and then from software as a service (SaaS)
to complete service enablement on a hosted infrastructure (IaaS). At the
same time, virtualization has emerged as a key enabler for the cloud
computing paradigm. Several challenges arise in the design,
implementation, and deployment of virtualized clouds.

HotCloud will provide a forum for academics as well as practitioners in
the field to share their experience, leverage each other's perspectives,
and identifynew/emerging "hot" trends in this area.

Topics of interest include but are not limited to the following:

* Platform as a service
* Software as a service
* Infrastructure as a service
* Elasticity and availability in a cloud
* Multi-tenancy
* Storage cloud
* Charging models and economics
* Power-efficient ("green") computing for clouds
* Virtual appliance management and composition
* Monitoring, troubleshooting, and failure recovery
* Cloud management and configuration
* Programming models
* Security and privacy in clouds
* New applications for clouds
* Mobile clouds
* Cloud usage scenarios


For more details on the submission process, please see the complete
Call for Papers at:
http://www.usenix.org/hotcloud10/cfpb

We look forward to receiving your submissions!

Anyone out there in MUUG-land use R at all (http://www.r-project.org/)
or do any sort of data mining? Wouldn't mind talking to you sometime
if so.

Thanks,

Subject: [RndTbl] software-based firewall appliance - opinions?
Message-ID: <007b01cacfa2$1f4c34e0$5de49ea0$@net>

I'm looking for an "appliance-style" software firewall distribution. 
Appliance as in I don't want to just do a general OS install, because 
non-technical users will have to do some administration of it at a later 
date.

Short list so far:
BSDRP
m0n0wall
pfSense
SmoothWallVyatta 
Core

One key problem is that I expect to need 802.1Q VLAN tagging support, 
which is why I'm not installing a Linksys WRT54G as the "firewall".  I 
also want at least a rudimentary GUI, as it won't always be technical 
people who need to make changes to the firewall configuration.

I'd love to hear from you if you've used any of the above.

Subject: [RndTbl] MP3 player update and request for info
Message-ID: <4BB176DB.8060902@gmail.com>

	I still haven't been able to get the video to work since the meeting. I 
tried all the recommendations. I just don't seem to find anything to 
convert to the .AMV format. Like I said at the meeting the single M$ 
application they include doesn't work either. I read somewhere I could 
patch ffmpeg but I'd rather not risk messing it up. It would be nice if 
I could install RockBox on it but unfortunately...

	The other update is I tried the e-book reader. The manual says all it 
does is .TXT files. This is reasonable. It's an open format and you 
can't get much simpler than a bunch of ASCII/UTF-8 formatted bytes 
strung together. The screen is a little small but that's OK too if I 
take off my glasses and read it in a lit room.

	The request relates to the e-book reader. Someone gave me a whole bunch 
of books they were finished with. Unfortunately the majority are in .PDF 
and .LIT format. Is there a conversion utility in Linux or OS X to 
convert them to a .TXT file? I suppose I could read them on the computer 
but that would defeat the purpose of the e-book reader.

	Considering I bought the device just for the voice recorder, I think it 
worked out reasonably well finding all these additional capabilities. 
Now if they'd only work properly... ;-)

I'm looking for [probably] short-term hosting of email *only*.  Already

Any recommendations?

My vote is on pfSense.
Extremely slick and makes configuring even complicated stuff like CARP reasonably straight forward.
I find the logo itself ugly but the web UI is very slick.

Big thumbs up and my best suggestion for those less inclined to dive into OpenBSD head first (yes I'm aware pfSense is FreeBSD based). :P
