I had success using gpart just a few weeks ago after I did
something.... umm... unplanned to a hard drive that contained imortant
data.

gpart hunts down the file system boundaries and then suggests the
location of the partition.  It took me a few tries to get used to the
CL syntax, and figure out which were the real boundaries, but it got
all my data back.  In your case you're using RAID which complicates
things a bit, but it's worth a shot.  By default gpart will take no
action, so it's perfectly safe to play with.

I've never seen LAMP specifically called out in formal training.  New
Horizons (http://www.nhmn.com) does formal linux training, and they
offer enough variety that you may find something that meets your
needs.

to be clear:

you are using high point hardware raid 5 on each controller.

so for conroller A - you have 4 250gb drives attached to it, in raid 5 
with 1 hot spare = 750gb usable.

controller B is the same setup.

then, inside of CentOS  - controller A raid5 volume shows up as /dev/sda 
and conroller B raid5 volume shows up as /dev/sdb.

then you create a raid 0 stripe of /dev/sda and /dev/sdb which would 
yield 1.5tb (approx) disk space.

then some disks stopped working and you have swapped out the power 
supply etc.

conrtoller A has one disk dead but the hot spare recovered so things are 
good on controller A (expect for now you don't have a hot spare) and 
CenOS sees /dev/sda just fine.

controller B has multiple disk failures and you only see 1 disk?  if 
this is the case i think your screwed.  controller B first has to be 
able to have enough good disks to build your hardware level raid5 
volume, which would then get presented to CentOS as /dev/sdb which is 
the other half of your CenOS raid-0 stripe.  until you can get at least 
2 disks running correctly on controller B - your raid-5 volume wont be 
there.  you need 2 of 3 at a minimum, which would be in a recovery 
state, and slow, but at least running.  then, if your CentOS raid-0 
won't mount you can start looking at that.

is this accurately - recapped?  if not, please clarify.

Hello TCLUG,

I have a CentOS vm with a 405 GB disk.  My issue is that there is
about 90 GB missing from an LV.

fdisk reports the size of /dev/sdb1 at 434 GB, pvdisplay reports 405
GB, lvdisplay reports 405 GB, but df -h report 312 GB.

Can anyone point me in the right direction?

I'll put the output of various things below.

Thanks,

Rob

What is the file system on that volume? Is it possible, that you have
extended the volume, but forgot to resize the file system?

Sunny, that is exactly what I missed.  Thanks!

FYI, resize2fs can be performed while the file system is mounted using
the 2.6 kernel and ext3 it would appear.

So, my college that was supposed to be offering a Linux program is
bailing on me and not offering the courses I need.  Does anyone know
of some places in town that would offer 3rd and 4th level courses in
Linux administration?  (As in, I've had the first two semesters of it,
and need the second two worth, but preferably concurrently.)

I have an old one -- not much color depth (8-bit/256-color, I think; 
maybe 16-bit).  Yours free for the pickup.

If you want a better one, or don't want to drive to my place in 
Woodbury, I'm 99% sure the MPC has a bin full of them for ~$5 
apiece,  If you haven't been there before, it's worth a trip just to 
scope them out.  They recycle old computers, and salvage some parts 
for resale at low prices.  Open Thu & Fri, 11am-5pm.

I have a custom built 4U Rackmount server for parts.  I just retired this machine after 4 years of use, but had problems with it after reloading the OS, so I'm selling it as-is. Im fairly certain the problem lies in the mobo, cpu, or ram.  

The case is very well built, and I have been extremely impressed with how easy it is to work with
http://www.newegg.com/ Product/ Product.aspx?Item =N82E16811182566

The PSU is an Antec 430 Watt.  Good brand name, very solid

As far as the other hardware:

NVidia Geforce4 ti4400 Agp graphics card
pci 10/100 network card
512 MB ram (I may have another 512 megs of ram somewhere to throw in the deal)

a specific address so that folks wouldn't need to spam the list with

I thought this was interesting:  Man puts iPhone in model rocket.  Uses 
accelerometers and GPS to track.  

Unfortunately, the iPhone can't log data beyond 3G (pun intended).

  http://www.mobileorchard.com/the-iphone-rocket/

Years ago, I worked on inertial accelerometers for aviation, and I can say 
that this appears slightly lower quality...  But what's interesting is that 
many people will now be carrying iPhones and Androids, both of which allow 
for easy deployment of software.  This is the first time that normal people 
have carried 'general purpose' computers with internet access.  

All sorts of wacky stuff is possible.

Has anyone made apps for Android (linux, java) yet?

A similar type of project using IBM Lenovo hardware and OpenBSD 
http://undeadly.org/cgi?action=article&sid=20060803130207


Snip from article

Chris Kuethe has written an application which, by taking advantage of some
unique OpenBSD features, has allowed him to turn his laptop into a race car
data logger.

aps(4) is a driver that utilizes the OpenBSD sensors framework to retrieve
and report various statistics provided by IBM/Lenovo Thinkpads. The
important ones here were the X and Y acceleration features, which provide
the same functionality found in expensive accelerometer devices.

Since a typical consumer GPS will only update its data once per second, and
a race car might be travelling in excess of 200 km/h, on its own, it is not
capable of generating much meaningful performance data. It is even less fit
to record information about turns and other sudden changes in position.
Digital signal processing and sound editing fans might recognize a parallel
problem: sampling frequencies too low to properly describe a signal
(Nyquist/Shannon Sampling Theorem, anyone?). Since GPS receivers that can
provide navigation solutions several times tend to be slightly expensive and
less common than those that produce only one solution per second, and 'real'
dataloggers are even more expensive, it occurred to Chris that he already
had all the necessary hardware, as well as a framework for putting it to use
for his task.

So, a friend of mine did an accidental rm on ALL of /var on a system.
We're wondering what our options are for getting that data back.  He
ctrl-Cd the deletion partway through when he realized what happened,
and shut off the system.  /var was its own partition, formatted as XFS
on top of LVM2 spanning two drives.  Each drive is 250GB, for 500GB
total system capacity.  /var was half of that, 250GB (but using both
drives via LVM).  Only about 500MB was used space.  Ideas?

Subject: [tclug-list] brute force gpg key?
Message-ID: <491AC51F.7030507@mtu.net>

I've got an old gpg key that I'd like to revoke, but forgot the whole
password and didn't keep a revocation cert around. Anyone have any
suggestions for an automated way to try a sequence of passwords against
gpg and figure out which one it is? I remember portions of the password
so I can narrow it down to about 1000 attempts.

Thanks.

Simple shell script with a while loop would do the trick.  If you have  
something you encrypted, simply run a command to decrypt that file,  
trying all the possible passphrases.  Check the exit code for gpg  
after each run.  When you get a 0, you've found your code.

I started down that path this morning, however I can't seem to figure
out how to automate passing the password to gpg. I figured I'd use
expect, but gpg *always* uses pinentry, so I loose the ability to use
stdin/stdout to communicate the password with gpg.

There are python and perl modules for GnuPG that allow you to use it
programmatically, including passing in a password programmatically.  The
python module is called GnuPGInterface, it was based on the perl module
(by the same author I believe)

I can provide you with sample code if you want.  Contact me off list.
(I pretend to be a python programmer for my day job)

That's helpful....

And now, for my equally helpful response.

If there is something textlike that you really really need back, you
might be able to find it with grep and dd.

But otherwise... I think your hosed.  XFS (and ext3 and reiserFS) all
write 0's over the block pointer when you delete, rather than just
marking them as unused.  If it were ext2, you could undelete the
files.

Sorry.

Now you have an excuse to reinstall and update your OS :)

And on that note, a song! (I think someone posted it to TCLUG years ago.)

To the tune of "If You're Happy and You Know it:"

If you can't afford to lose it back it up.
*clap*clap*clap*
If you can't afford to lose it back it up.
*clap*clap*clap*
If you can't afford to lose it
Then there's no way to excuse it
If you can't afford to lose it back it up.
*clap*clap*clap*

As the system is spanning over two drives with no redundance you've
already doubled your risk of catastrophic disk failure.

If you don't have a backup:
- Did you take this opportunity to create a backup of any remaining
critical data before you try and recover? If not, there's no time like
the present. We'll wait.

- Do you have a similar system you could copy the missing var files from?
- Can you install a similar system that you could copy the missing var
files from?
- Can most of /var be restored from the original install media?
- Last resort: Reinstall and then restore the critical data that you
backed up above.

If it was really critical data that was lost without a backup, Kroll
Ontrack in Eden Prairie might be able to recover data, but you'll
learn just how valuable your data is. ($600-$3000 for a single drive,
possibly more for a spanning set such as yours.)

And, without trying to look like an ass, though I usually do anyway,  
I'd recommend putting a solid backup routine in place.  Honestly, with  
drives the size they are and inexpensive as they are, there's no  
*good* excuse for not having a backup routine.

If you're not sure how to go about building a backup routine, I'd be  
willing to help, as I'm sure many members of this list would be.

Thanks all.  The consensus seems to be that it's just gone - even
Kroll said they probably couldn't do it.

As far as backups go, we're well aware.  :P  It's a new server and we
just hadn't gotten it all set up yet.  (Yeah, it would have been
smarter to not use it at all until that was in place, but that's not
my call.)  There's still lots to do for it, but nobody with the time
to do it quickly enough.

In case you're curious, my current plan is to use Bacula, with some
kinds of files in version control, then daily/weekly backups to disk
and weekly or monthly backups to DVD.  Maybe some over the network too
- we'll see.

The installfest was really great for me.  Many people were there 
struggling with their various tricky problems.  I was one of them.  There 
were a few quite helpful people around -- Brian was especially good.

In my case I need to install a software RAID (RAID1 -- drives mirror each 
other) and it was good to have some help with that.  We had to use the 
Ubuntu 8.10 "alternate" installation CD.  It took a few tries but we did 
it.  Then the big problem -- my video card wasn't working!  Huge hassle 
and I left without working X.  But when I got home I did some googling and 
I figured out the problem.  Now it's working great.  (Unfortunately I had 
to install a non-free ATI Radeon driver, oh well.)

I was there for more than 5 hours fighting with this machine.  Where else 
can you find people who will hang out and help you for five hours?!  It 
was a huge favor to me and I really appreciate it.  I also ate pizza, 
donuts, soda and coffee (healthy stuff!) and didn't pay for any of it, 
which seems wrong, but I tried to pay and they wouldn't take my money. 
Maybe I can pay next time or send a check to someone.

I'm not sure what kinds of services are available for what I want.  I 
think the best thing for me would be to have a place that allowed me to 
house a server and charged me for bandwidth.  I would connect by ssh to do 
system administration.  The server would do email, web, and maybe other 
stuff too.  It wouldn't be a bandwidth hog because.

Is what I need called a "colo" (colocation) center?  Whether it is called 
that or not, who should I go to in the twin cities for this kind of 
service?

Yes, this is colocation. It's pricey, compared to renting bandwidth,
but that depends on what sort of pipe you have to your server location
too.

I have been an ipHouse customer for years (since before 2000), and have
been very happy with them. They provide all sorts of options, including
colocation.

yes. alternatively, find a vps provider where you have root on a virtual 
server, and don't have to worry about the hardware that way.  ;)

Pretty much every ISP in the area offers it. ipHouse, VISI, Time Warner 
Telecom, etc.

I'm not sure what you're looking for, or what your price range is, but I
have found that leasing a server can be a far better deal than collocating
your own.  I currently lease a server from xlhost.com for around $60 a
month.  That gets me a dedicated server (not a shared virtual machine, an
actual box), 1TB of traffic a month, 10Mbps dedicated up/down connection, 5
static IP addresses, and your os of choice.

I realize this may be overkill for what you need, but in my opinion its
better than colocating.

That sounds pretty good, but I guess their prices have gone up:

http://xlhost.com/

If I were to run email distribution lists from there, that could add up to 
a lot of bandwidth, I guess.  I assume that email bandwidth costs the same 
as other kinds of bandwidth.

I assume I get to have root permissions on my leased box.

A cheap non-local option is a dedicated server from Core Networks
(http://corenetworks.net/dedicated/). I've had good luck with the
Starter package, and the IP KVM was very useful when I screwed up my
SSH server ;)

These are bare servers when you get them, you can install any prebuilt
image Core Networks has or you can use the IP KVM to install your own
OS.

Of course the servers are a little undersized and I don't know about
fault tolerance, but this was a perfect option for me. Co-location
seems to be at least $100/month and you have to provide your own
hardware.

Check out their bargain bin specials: http://xlhost.com/bargainbin.php  It
looks like they still have a couple left for 59.99 a month.  I wouldn't be
too worried about the bandwith, they provide some bandwith monitoring tools,
and buying an extra TB of bandwith a month isn't the end of the world if its
needed ($50 extra, not as outrageous as some companies charge).

I assume I get to have root permissions on my leased box.


You get complete root access to the machine, and for the most part they
don't care what you do with it (read the fine print for restrictions).

I've looked around quite a bit for hosting services, and this has been one
of the better deals for what you get, and their service has always been
outstanding.

Slichost starts at $20/mo, and you get root and your choice of distro, as well 
as access to the console.

Well - as long as we're recommending VPS providers, I'll throw
linode.com into the arena. I've been with these guys for nearly 5
years now and have yet to have a single issue with them that wasn't
resolved within a couple of hours. Chris Aker, the owner, and his 5
other staff members are regularly in #linode on irc.oftc.net, and are
always willing to ask questions or just chat about linuxy stuff.

Linode has cabinets in 4 different datacenters around the US (Dallas,
Atlanta, Newark, Fremont), and they have 6 different sized VPS
packages, depending on your needs. They support cool things like IP
failover, disk image cloning between linodes, and they have a private
"back end" network that is available to you for inter-linode traffic.
Traffic that goes over this private network doesn't get counted
against your monthly bandwidth allotment. They have pre-made disk
images for all the major distros that are available to you, or you
have the option to "roll your own" disk image if you prefer.

Okay, this is sounding like a sales pitch, so I'll stop now.

Since we're all recommending things, I suggest http://www.webhostingtalk.com

You can find reviews and good deals on VPS, colo, as well as dedicated 
servers.

I'm considering SliceHost.  Has anyone had good/bad personal
experience with them?   Unexpected outages?  Hard to get console?
Unexpected bills?  Above-and-beyond service?

Comments that are post-merger are especially appreciated.

Thanks

I've had good experiences with Slicehost.  Their support department is 
flexible and responsive.  Their tutorials online are awesome (useful even if 
you are setting up your own ubuntu server elsewhere).  Console is available 
through the web and works well.  

I haven't seen any real changes yet after the buyout.  Although, their 
management console was down last week (from my pc at least) for several 
hours, but none of our servers (nor our clients) were affected, and I haven't 
seen that before nor since.

I plan to stick with them for small projects.  Anything that needs clustering 
I'll probably do on EC2.  You can do it on slicehost, but EC2 seems to have 
more powerful tools in this area.

As I said previously in this thread, I've been a happy
customer of ipHouse for about a decade, and another poster
mentioned VISI and some other local providers.

ipHouse was a merge of three or four other local ISP's (Bitstream, ProNS, 
and Goldengate for sure.. possiblyo ne more, can't recall.) Perhaps John 
was a client of one of those for awhile?

Indeed, he mailed me off list to say he was with goldengate.  Still,
geeks are precise people - can you really give iphouse credit for time
served with goldengate?  I'm just saying, ..  

Now if he were a client of visi in the 90's, when it was run by the
people who now run iphouse, it might be worth mentioning.

SGI Indy2 with monitor and IndyCam.  Workstation is functional, but monitor needs calibration (image compressed and quickly rolling), so I can't readily log in to determine full details of the hardware.  Also includes a second set of memory SIMMs for upgrade.  $150/best offer.

We are thinking about putting together a cluster of maybe 10 machines, 
presumably using GNU/Linux.  Do any of you have experience with this?

Some of the things I'm wondering about include the appropriate 
configuration of machines -- isn't it better in terms of cost/benefit to 
buy fewer dual quad-core machines than more single CPU machines, 
especially if the jobs are not very memory-instensive?

We certainly want to use shared disks, but is there any problem with 
booting all the computers from the same network drive?  That seems like a 
good idea to me rather than to have separate HDDs in the machines, but I'm 
not sure how it is done.

What free software is available for managing jobs, e.g., batch queuing?

FYI ... The idea is to use these machines for our genetic analyses -- 
maybe 600,000 SNPs on 7,500 people, but this mostly consists of running 
one SNP at a time on some collection of traits.  I don't think the memory 
requirements are too great unless we try to load a lot of the data at 
once.

It just so happens that the following link uses FreeBSD as the OS, but  
you should be able to easily adapt this to linux:

Hi Mike,

There are tons of groups on campus doing this so contact me off list if 
you want to discuss it.

Fewer machines with more cores per machine is a bit more cost effective 
when it comes to the infrastructure to support it (power, cooling, 
space, network devices). Since the jobs aren't memory intensive, go for 
a many core system, but in case you want to use the cluster for 
something else in the future that may be memory intensive, you'll be a 
bit out of luck. Depending on which sort of processor/chipset you buy 
such as the AMD Opterons or the new Intel Core i7 processors (when they 
get ECC memory), it would not be as big of a hit.

Shared disks are the standard and there are ways of differentiating 
nodes while still booting mostly from the same media. I would recommend 
looking into Rocks (http://www.rocksclusters.org) as it would get you 
going the quickest. For managing jobs there is Torque/Maui, or Sun Grid 
Engine which does a lot of work for you that Torque does and then some.

You might want to take a look at what the folks at UW are doing with Condor:

http://www.cs.wisc.edu/condor/

That being said, I'm sure you're not the only one at the U whose  
looking to do this, I have to imagine there are quite a few folks at  
it already. Are there any internal peer groups or other ways to

A co-lo is when your hardware sits on their network.  All they do is
provide power, cooling, network, and the occasional operator to press a
reset button should that be necessary.  You would be responsible for all
patches, backup, and other sysadmin tasks.  If you're not up to that,
then a managed server would be easier but more expensive.

Another option, if bandwidth isn't a factor, is to host it yourself on a
residential DSL or cable modem (at your home or a friend's).  This has
the benefit of putting the hardware within easy reach should that be
necessary.  Actiontech and Linksys routers have a "port forwarding"
option that needs to be configured.

Depending on your provider, there may be policies against re-selling
service, but I've never had any problem running a hobby server.  I've
found I need to relay email thru their smart host to get pass some
corporate spam filters.

Subject: LameDuck - CodeWeavers CrossOver Upgrade Deal


Dear CodeWeavers Customer,

On Tuesday, October 28th, 2008, you participated in one of the single 
biggest Internet phenomenon's in recent years!  During that 24-hour 
period, CodeWeavers gave away $45 million of software to 650,000 new users 
from around the world. We gave away more licenses of our software, 
CrossOver Professional, than any software firm has ever given away in such 
a short timeframe--26 terabytes worth!  Yes, we are still in business; 
however, our servers melted!  Our Internet connection crashed!  And our 
network admin still hasn't recovered! But in the end (and thanks to you), 
the promotion was a complete and unprecedented success!  We hope you 
enjoyed the ?world famous' Lame Duck Challenge (LDC).

I've been a fan of KDE since Mandrake v9.
Coming from a Unix command line and Windows environment KDE just seemed to make more "sense" to me.

So I have been playing with Kubuntu 8.10 and Ubuntu 8.10 on a slightly older computer.  I had read an article that one former KDE fan moved to Gnome so I was intrigued.

An HP Pavilion 541c with a GeForce2 video card.
This is an AMD 1.67GHz processor with 1GB of ram, so it's not a bad computer (OK, the video card isn't that great).

First problem...
The computer is on a KVM so the auto discovery of the monitor did not work.

Kubuntu with KDE4. 
This desktop environment makes no sense any more, plus they took out the option to specify the type of monitor I'm using. So I dig around on Google and find the proper configuration for xorg.conf and presto I have the resolution I like. I'll grant you the video card isn't great, but KDE 3.5 didn't have a problem showing new menus or windows. Every time I tried to open the main menu, it freaks out for a few seconds and then shows me the menu. Processor and system load.... Don't even go there. KDE4 is worse than Windows on this machine and that is quite the "kiss of death" in my mind.

Wipe hard drive and start over.

Ubuntu 8.10
This is Gnome? Did I step into an alternate universe where KDE and Gnome are switched? The menus actually make sense to me. I can add/remove buttons from the menu bars without even having to think about it. It still didn't auto discover my monitor, but that was to be expected. Grab the same xorg.conf file from before and all is well. No weirdness opening menu items and the processor and system load isn't half bad either.

Additional tidbit...
Ubuntu 8.10 also runs well on a duo 400MHz processor system with 512MB of RAM with some ancient AGP video card. I would not even try Kubuntu 8.10 on that machine after it's poor performance on the AMD.

Guess the guy with the "black tower" in the article I read isn't the only one to decide that KDE4 just isn't the answer any more. Hello Gnome, goodbye KDE.

Converting is a pain because it requires new syntax and essentially new programming.

I think I saw stuff about WINE and its brethren having a way to use DOS batch files directly.  Google for THAT.  Might be as simple
as piping it through COMMAND.COM

I had a similar experience. I have been a fan of KDE for a very long time
and have my tweaks, shortcuts and tricks all documented meticulously for my
own use when I set up a new machine or start over or upgrade. And then one
day I upgraded from Fedora 8 to Fedora 9. KDE4 was a nightmare. I couldn't
find one thing that I liked about it over KDE3.5. Simple things like
changing the size of the icons or changing the size of the taskbar or even
locking/unlocking the taskbar screwed it up. I just couldn't stand it! I
promptly pulled out my Fedora 8 DVD and reinstalled it. I don't think I want
to upgrade to Fedora 9 nor do I want to use Gnome. Unfortunately, once
Fedora 10 comes out, there won't be any updates available for Fedora 8 and I
don't know what I will do then. :(

But then it will run everything in the context of the WINE environment,
without the access to files or other utilities (which I suspect is the
main point of running it under Unix in the first place).

Does KDE4 still allow Konqueror to be used as the file manager?   Dolphin is 
weak.

Heh, good question. I really don't know. 
Didn't really look into that. I was so disappointed with the "strangeness" and poor performance that I didn't give it more than a few hours of play time before wiping it clean and installing Ubuntu.

I'm not even sure what I have for a file manager on my Kubuntu v7.04 box.
I'm just using whatever was present "out of the box".
I don't really customize a lot except to get things working the way I like.
That is why I had to 'play' with v8.10 before I upgrade my v7.04 box.

This question is about local places that can do data recovery work, so it

happened to be running Windows XP on a Dell laptop.

What local computer pros might be able to get some data off of this HDD? 
Here's what happened:

The Dell laptop's HDD had failed during the summer and the drive was

Not sure on local places, but you could check out seagate's data recovery
services: http://services.seagate.com/

You can try using their data recovery software for free, and if it detects
it can recover the data from the drive, you can then purchase it for $130.
Not sure how this compares with other data recovery services, but I know
other places can get pretty expensive (in the 1000's).

If you can, always make a copy of the drive and work on restoring data from
the copy.  You want to preserve the original disk as much as possible.  The
easiest way to make a 1:1 copy of a drive would be dd

dd if=/dev/sda of=/dev/sdb  (sda = original disk, sdb = blank disk)

Good luck,
Andy

Ontrack is in Eden Prairie.  But you quickly find out what your data
means to you, the bill gets to 4 figures fast.

If you don't mind shipping it (or driving to Madison) Gillware won't

Similar experience here.  Upgraded to Fedora 9 a while ago... and
hated KDE 4.  Stuck with it a while, through the bug release updates,
hoping it would get better.  It hasn't.  It still sucks.

The KDE 3.5 that I'm running on another Ubuntu system is _far_ better
than this mess.

Without even going into all the details of the little things that are
wrong with KDE 4, I can't even find a stable combination.  On Fedora
9, this thing completely hangs the X server out of the blue about once
a week.  Immensely frustrating.

I'm done with Fedora.  On top of the buggy KDE release, it seems like
every single patch update they push completely breaks my system one
way or another.  Ever version upgrade is a day long mis-adventure of
trying to make my system boot and use the monitors again.

Some day soon, when I'm ready for the pain of a complete reinstall on
this system, I'll be switching it to Ubuntu.  Hopefully they still
offer KDE 3.5 in the latest Ubuntu?  I haven't tried it yet.

It's funny how Fedora has slowly gone from one of if not the best
distributions, to its current state.  Meanwhile, Ubuntu has just
rocketed to the top.

I haven't used Fedora, but the Register gave an awfully nice review to 
Fedora 10. They're using GNOME however.

If you meant the latest Kubuntu, unfortunately, you are out of luck - I
tried their live CD (when it was 8.04.01) and it already had KDE 4. I am
quite certain Kubuntu 8.10 comes with KDE 4. :-(

I'll second the recommendation of Kroll Ontrack.  They're basically
THE world leaders in the business of data recovery of various sorts.
He's also right about the cost.  I recently contacted them for a
business acquaintance, and thankfully for us the data was of the sort
that we were able to decide that it wasn't worth the money to us
(around $1600, iirc).  However, there is the perk of that they will
spend time talking to about the details of the problem and get you an
estimate of both the price and what data they would likely be able to
recover, and were refreshingly honest about the prospects for the
latter, which I hadn't quite expected initially.  The customer service
guy gave me a general answer, but wasn't satisfied with that himself,
so got in touch with the engineer specializing in the filesystem we
were using and called me back with him on the phone too.  They
definitely have their act together, but do consider ahead of time what
the data is actually worth to you.

Hello-

On my Windows box, I have a program called Putty Command Sender, which
will execute a command on all existing Putty instances, or a subset of
them based on a filter.

Is there a good way to do this in Gnome? Whether with gnome-terminal
or another term program?

Would you mind telling us what you use it for?  I'm curious.  Also, if I

I have 10 servers which I deploy applications on. I just copy the file
to the server, validate the md5sum, rm the old application, and untar
the new one.

OK.  Here's something I haven't used myself, but I think it is the sort of 
thing you'll be wanting to do.  You can set up ssh so that you can log in 
securely without a password.  Read about "ssh-keygen" and related 
programs.  There are man pages and there should be plenty of step-by-step 
guides on the web (maybe someone else on this list will know which are 
best).  You can then use scripts to run commands on the remote systems:

ssh system1 "command args filenames"
ssh system2 "command args filenames"
ssh system3 "command args filenames"

I think you will discover that this makes your life a lot easier than use 
of PuTTY on Windows.  You can even do this kind of stuff with 
stdin/stdout:

cat file.tgz | ssh system "rm oldfiles ; cat - > file.tgz ; md5sum file.tgz ; tar zxf file.tgz ; whatever"

The stdout from md5sum goes to you on the local machine.  I have tested 
this and it works.  I had to enter my password though, but you can set it 
up with keygen and avoid that step.

Using a bash script, you can make it so that you maintain a list of system 
names in a file, then tell bash that for every system in the file it 
should do the following...

Great question! This would be handy indeed.

You could start a GNU Screen session that opens SSH connections to each
box, then use this script to multiplex the command:
http://harnly.net/2005/blog/geek/macosx/gnu-screen/

But that's more than a handful of moving parts, and it is fairly manual.
I'd automate it using a shell script:

I think drue's suggestion of clusterssh was probably the most  
helpful... Just my two cents.

A couple more cents - like a reason -- wouldn't hurt, but thanks for 
reminding us about the ClusterSSH suggestion.  I just looked it up:

http://clusterssh.wiki.sourceforge.net/FAQ

I'm not sure of how certain aspects work, but it looks to me like the 
ssh-keygen is something he'll have to do for ClusterSSH unless he wants to 
type 10 passwords every time.  After that he gets to see 10 windows at 
once all doing the same thing -- for no good reason? -- and he types 
commands instead of executing scripts.  That might be better, but I don't 
see how.  It sounds like it is more similar to what he is used to with 
PuTTY though.

On the other hand, if his task were more ad hoc and less automated, I can 
see where ClusterSSH would be handy.  But would it still be a good 
solution for 100 servers?  Or even 30 servers?

Kevin's original post stated he wanted something to execute a command  
on existing instances, or a subset of them.  I would say that  
clusterssh fits that criteria most directly.  Writing a shell script  
to execute a series of commands on remote systems wasn't something he  
asked for.  There's your 'reason.'

As far as ssh keys and such being set up, that's really out of the  
scope of his question.  I've used clusterssh to edit the same file  
(vipw, for instance) on 30+ hosts at the same time.  It gets a bit  
cumbersome, but at least I can see what's going on in each instance,  
without writing a complicated script to do the same.

That was my mistake, I guess, but I think it is good to discuss related 
topics.  It isn't as if all of us know every way of doing everything and 
can't profit from hearing about something we are not using.  If he knew 
already all the stuff I wrote about and couldn't do anything with it, I'll 
be surprised.

It wouldn't be much of a list if everyone sent one-liners as answers. 
Someone could reply...

clusterssh

...and someone else could chime in...

rsync

...and that would be the full content of two messages.  I prefer to have 
discussions about how to do things and I especially liked Adam's reply 
because I could learn something from it.

There is something that I've stumbled upon last week.  I have yet to
use it, but it might be just what you want:

Thanks for all the replies. I guess I should have mentioned I need
this for alot of ad hoc commands as well as standard deployments.
Cluster SSH seems to work great for what I need it to do, now to just
fiddle with the script a little to get the tiling to work as I like ;)

Another option, if you're haven't entirely settled on ClusterSSH, is pdsh:
http://sourceforge.net/projects/pdsh/

We use it extensively and are quite happy with it.

HTH,

Check out Capistrano.  It's used in the Ruby on Rails world to deploy servers 
and updates, but it also works outside rails.

You can define a set of servers and credentials, the just say 

  run "some_linux_command --options"
or
  sudo "some_linux_command --options"
