• How to use qcow2 disk image in Linux?

  - by sauparna

  I have a large qcow2 formatted disk image, which I use as storage. Often I need to move data to and from this disk image. I mount the disk using the qemu-nbd tool as follows: modprobe nbd max_part=63 qemu-nbd -c /dev/nbd0 /host/disk100G.img mount /dev/nbd0p1 /home/rup/disk But disk access fails every now and then in the midst of some I/O operation with an "Input/output error". At that point I have to manually unmount the disk and re-mount it so that I can run the program again: qemu-nbd -d /dev/nbd0 umount joborkhaki/ What could be the reason for this? Is there a better tool that I can use to maintain a qcow2 disk image?

• Manage Upload Permissions, SFTP & Linux

  - by John R

  I'm new to Linux. I am working with a Redhat 5.5 server and am using a Java-based SFTP script that will allow multiple users to upload text files to a server. I am undecided if each user will have a separate directory or if I will use a naming convention that includes their customer ID. The files include some personal information about their LAN settings, so I prefer to use SFTP as apposed to FTP. It is my understanding that SFTP is encrypted (Also, I have a Java class configured to upload via SFTP, so I prefer not to switch protocols unless their is a very-good reason). The prototype is for a system that will support large numbers of customers and the thought of continually adding and removing clients through the command line seems highly impractical. (Again, I am new_to/learning Linux and Redhat). What are normal conventions for giving multiple users permission to SFTP upload files with a unique username and password for each.

• Two questions about restoring Thunderbird from a backup

  - by Eric

  Setting up a new Windows 7 PC, I'm puzzled by two things in Thunderbird 3.1.9: I restored a profile from a three-month old backup, no problem. I then copied more recent files into the Mail/ directory, but TBird still shows the old messages. The last message in Inbox is dated 3/16/2011 -- how do I get TBird to display all the messages in the Local Folders/Inbox view? A large number of the existing messages are now displayed in separate tabs -- I can't tell you how many, but there could be over 1000. Which file governs this? Or can I hire someone from Mechanical Turk to come over and manually close each tab?

• SCCM 2007 managing hosts in non trusted forest

  - by BoxerBucks

  I have an implementation of SCCM 2007 in forest "A" that manages hosts in that Windows 2008 forest. There is another forest/domain, "B", which I have no trust with that I need to manage hosts in as well. I don't need to push out clients from the SCCM console, I am going to install them manually. I just need the hosts in domain "B" to connect back to the forest/domain "A" for management purposes. To date, I have not added any AD objects to domain "B" for hosts to query for site, SLP or management point info. I am installing the hosts with the command line: ccmsetup.exe /mp:SCCM_Server /site:mysite SCCM_Server = FQDN of my sccm server (which is resolvable by the client) There are no ACL's between the two servers. From the logs, I can see the install complete and the client tries to query the local AD for the site info for "mysite" but it can't find it and it stops and never connects. Can anyone give me some direction as to how this should be setup?

• Is it possible to load balance requests from a single source?

  - by Shawn

  In our application, Server A establishes a TCP connection with Server B, then it sends a large amount of requests to Server B over the TCP connection. The request message is XML-based. Server B needs to respond within a very short period, and it takes time to process the requests. So we hope a load balancer can be introduced and we can expedite the processing by using multiple Server B's. This is not a web application. I did some research but failed to find a similar application of load balancer. Can anyone tell me if there's a load balancer can help in our application?

• Postgres 9.0 locking up, 100% CPU

  - by Jake

  We are having a problem where our Postgres 9.0 server occasionally locks up and kills our webapp. Restarting Postgres fixes the problem. Here's what I've been able to observe: First, usage of one CPU jumps to 100% for a few minutes Disk operations drop to ~0 during this time Database operations drop to 0 (blocks and tuples per sec) Logs show during this time: WARNING: worker took too long to start; cancelled WARNING: worker took too long to start; cancelled No Queries in logs (only those over 200ms are logged) No unusually long-running queries logged before or during Then the second CPU jumps to 100% The number of postgres processes jumps from the usual 8-10 to ~20 Matched by a spike in Postgres Blocks per second (about twice normal) Logs show LOG: could not accept SSL connection: EOF detected Queries are running but slow Restarting postgres returns everything to normal Setup: Server: Amazon EC2 Large Ubuntu 10.04.2 LTS Postgres 9.0.3 Dedicated DB server Does anyone have any idea what's causing this? Or any suggestions about what else I should be checking out?

• 19" Rackmountable fast storage arrays

  - by Eruditass

  I'm in need of some fast (15+ GB/s write) and somewhat large (50 TB+) storage subsystem with a standard storage interface. I'd prefer something other than Fibre Channel, which admittedly appears to be the most standard interface. RAID 5 is sufficient. What are the cheapest / smallest products from vendors to look at for building this subsystem? I've looked at DDN and TMS so far. Small: Under 20U Cheap: Under a million Edit: I'd really like to cut back costs as much as possible at the expense of capacity. How cheap can these bandwidth requirements be met?

• Cannot resize OS X partition

  - by David Pearce

  I am trying to resize my existing Mac OS Extended partition on my Macbook to install Windows 7 (using steps similar to these), but when ever I go to apply the changes, I get this error: Partition failed Partition failed with the error: The partition cannot be resized. Try reducing the amount of change in the size of the partition. The total capacity of the hard drive in question is 260GB, with the entirety being taken up by the OS X boot partition. There is I am aiming to shrink that partition down to 60GB. How can I fix this problem? I have been reducing the amount of change by 10GB each attempt, but it still is not working. I assume the problem is that there is not a large amount of continuous space on the device. Is there some way to can do a manual defrag that would rectify this problem?

• MySQL is killing the server IO.

  - by OneOfOne

  I manage a fairly large/busy vBulletin forums (~2-3k requests per second, running on gigenet cloud), the database is ~ 10 GB (~9 milion posts, ~60 queries per second), lately MySQL have been grinding the disk like there's no tomorrow according to iotop and slowing the site.

• No icons in top panel notification area

  - by PeterOakland

  (writing here because my reply to a previous post is marked "deleted by diago") Ubuntu 9.10 Karmic I have tried removing the notification area from the top panel and reinstalling it, and still I have nothing in it: no volume control, no connection icon. I have put a notification area on the bottom panel, and the only icon appearing is the connection one, looks like two plugs meeting, or a large resistor in line, or two toilet plungers face to face, so to speak. How can I get this up top where it used to be, along with the volume control icon? Thanks for any help.

• Server Configuration / Important Parameter for 500Req/Second

  - by Sparsh Gupta

  I am configuring a server to be used as nginx server for a very heavy traffic website. It is expected to receive traffic from a large number of IP addresses simultaneously. It is expected to get 500Req/Second with atleast 20Million unique IPs connecting it. One of the problems I noticed in my previos server was related to iptables / ipconntrack. I am not aware of this behaviour and would be glad to know which all parameters of a ubuntu / debian (32/64) bit machine should I tweek to get maximum performance from the server. I can put in a lot of RAM on the server but mission critical task is the response times. We ideally dont want any connection to be hanging / timing out / waiting and want as low as possible overall response times. P.S. We are also looking for a kick ass freelancer system admin who can help us figuring / setting this all up. Reach me incase you have some spare time and interested in working on some very heavy traffic website servers.

• Where can I find a useful Unicode fallback font for Mac OS X?

  - by Stephen Jennings

  On every browser I've tried (Firefox, Safari, Chrome, and Omniweb), when I go to a web page containing somewhat less-common characters, I can't see the glyphs. For example, on the Wikipedia page for the Bengali Language, the very first line contains a string of squares; on Windows, I can see the Bengali writing. On Windows, as long as I have the Arial Unicode MS font installed, these characters fall back to that font and display properly. Mac OS X doesn't seem to ship with a font containing these Unicode characters (it has Arial Unicode MS, but it must be a subset of the Windows version because Bengali doesn't display in that font). I checked on my Snow Leopard DVD and I installed "Additional Fonts" from the Optional Installs package, but I'm still missing many languages. Is there any good, free font that contains a large collection of languages? I know creating fonts is difficult and time-consuming, but it seems like including at least one font like this with operating systems should be standard by now.

• Linux wget, how to display progress percentage after session has reload?

  - by skyrail

  I am running debian Squeeze in console mode on a plug computer. I control it opening an SSH session from a Windows machine, on the same local network. I started downloading a large file using wget. What I get is a console progress bar showing the percentage of data downloaded, file size, and download rate. When I close the session, debian is still running and downloading. Fine. But When I close and reopen a session, how can see which amount of data was downloaded, using a linux command ? thanks.

• How to warehouse data that is not needed from MS SQL server

  - by I__

  I have been asked to truncate a large table in MS SQL Server 2008. The data is not needed but might be needed once every two years. It will NEVER have to be changed, only viewed. The question is, since I don't need the data on a day-to-day basis, what do I do with it to protect and back it up? Please keep in mind that I will need to have it accessible maybe once every two years, and it is FINE for us if the recovery process takes a few hours. The entire table is about 3 million rows and I need to truncate it to about 1 million rows.

• Network bottleneck/throttling issue

  - by Gavin

  Hi all, It's my first day at a new company and i've been given the task to find out an issue with the internet connection. I noticed that whilst I was downloading a large file, the network grinds to a halt, except for my download. At first I thought it was the internet connection/modem but it seems that whilst the lockdown occurs, I am unable to access any network device. Has anyone experienced this before and if so, do you have any pointers? Looking at the setup. They have an DSL modem that connects to a 10/100 switch. There are only 5-6 computers on the network. Cheers Gavin

• SharePoint Item Edit Form (editform.aspx) keeps closing webparts - MOSS 2007

  - by poolybit

  We have a custom list within MOSS 2007 which sporadically closes the edit forms web part, despite the fact that the web parts property 'allow close' is unticked. The only way to make the form work again is to edit the page in SharePoint Designer and untick the option of 'web part closed', this then allows the form to function but at a seemingly random interval it will close itself again. There is quite a large user base accessing the site/list at anyone time, also note this has happened once on another list on another site collection. Has anyone else experienced this issue before or can offer any advice?

• Http 400 'Bad Request' and win32status 1450 when larger messages are sended to a WCF service

  - by Tim Mahy

  Hi all, we sometimes receive Http 400 bad request resultcodes when posting a large file (10mb) to a WCF service hosted in IIS 6. We can reproduce this using SOAP UI and it seems that it is unpredictable when this happens. In our WCF log the call is not received, so we believe that the request does not reach the ASP.NET nor WCF runtime. This happens on multiple websites on the same machine each having their own application pool. All IIS settings are default, only in ASP.NET and WCF we allow bigger readerQuota's etc.... The win32status that is logged in the IIS log is 1450 which we think means "error no system resources". So now the question: a) how can we solve this b) (when a is not applicable :) ) which performance counters or logs are usefull to learn more about this problem? greetings, Tim

• Free Windows traffic monitor that can run a command when reaching a limit

  - by leromarinvit

  Does anyone know a free traffic monitor tool for Windows XP which can run a configurable program when reaching a limit? Hoo Net Meter and DU Meter can do that, but they both cost money. What I'm trying to do is throttle the connection when getting close to the monthly limit, so that watching YouTube or downloading large files isn't fun any longer, but e-mail or looking something up still work. The throttling part is settled, Traffic Shaper XP works nicely. I just need something to automatically call a batch script when reaching the limit.

• Copying files locally on a network folder

  - by Altay_H

  I noticed that copying a large file from one location on a network drive to another location on the same network drive takes much longer than copying it locally. Instead of copying the file locally, the network computer sends the file to my remote computer, which sends it back to the same network computer. This means the files are being transferred over the network completely unnecessarily. Is there a way to fix this issue? It's becoming a real hassle to manage the video files on my network drive. Note: This is the case with both Windows and Linux (using Samba) network folders.

• Active Directory Password Policy Problem

  - by Will

  To Clarify: my question is why isn't my password policy applying to people in the domain. Hey guys, having trouble with our password policy in Active Directory. Sometimes it just helps me to type out what I’m seeing It appears to not be applying properly across the board. I am new to this environment and AD in general but I think I have a general grasp of what should be going on. It’s a pretty simple AD setup without too many Group Policies being applied. It looks something like this DOMAIN Default Domain Policy (link enabled) Password Policy (link enabled and enforce) Personal OU Force Password Change (completely empty nothing in this GPO) IT OU Lockout Policy (link enabled and enforced) CS OU Lockout Policy Accouting OU Lockout Policy The password policy and default domain policy both define the same things under Computer ConfigWindows seetings sec settings Account Policies / Password Policy Enforce password History : 24 passwords remembered Maximum Password age : 180 days Min password age: 14 days Minimum Password Length: 6 characters Password must meet complexity requirements: Enabled Store Passwords using reversible encryption: Disabled Account Policies / Account Lockout Policy Account Lockout Duration 10080 Minutes Account Lockout Threshold: 5 invalid login attempts Reset Account Lockout Counter after : 30 minutes IT lockout This just sets the screen saver settings to lock computers when the user is Idle. After running Group Policy modeling it seems like the password policy and default domain policy is getting applied to everyone.

• GPO best practices : Security-Group Filtering Versus OU

  - by Olivier Rochaix

  Good afternoon everyone, I'm quite new to Active Directory stuff. After upgraded Functional level of our AD from 2003 to 2008 R2 (I need it to put fine-grained password policy), I then start to reorganized my OUs. I keep in mind that a good OU organization facilitate application of GPO (and maybe GPP).But in the end, it feels more natural for me to use Security-group filtering (from Scope tab) to apply my policies, instead of direct OU. Do you think it is a good practice or should I stick to OU ? We are a small organisation with 20 users and 30-35 computers. So, we got a simple OU tree, but more subtle split with security-groups. The OU tree doesn't contain any objects except at the bottom level. Each bottom level OU contains Computers,Users, and of course security groups. These security groups contains Users & Computers of the same OU. Thanks for your advices, Olivier

• Move some iTunes library items to different drive?

  - by Sören Kuklau

  My internal hard drive is somewhat small, and I only regularly listen to a fraction of my iTunes library anyway, so I'd like to keep large portions on it on an external drive for archival purposes. Since dealing with multiple iTunes libraries is somewhat painful, the solution I'm looking for is to move individual items of the library to a different location, without compromising the "Keep organized" and "Copy files" settings. I found an AppleScript that I assume is supposed to do this, Move Files To Folder…, but it instead copies them, and doesn't update the library accordingly. I can do this manually by moving the file, then accessing it in iTunes — it'll prompt me for the new location. I just don't intend to do this one by one for thousands of files.

• Adding multiple gradients to object in Adobe Illustrator

  - by Vass

  Hi, I have an object which is a path (a nose to be specific). Now I want both a linear gradient and a radial gradient to be added to the object. So these must be separate gradient objects I guess, and I can't find a way to add multiple separate gradients to a complete path so do I duplicate the object and then apply a new gradient to each object? And what would the layer transparency features look like? Would the 'normal' overlay of the layers work? I am afraid of multiple shadows creating double dark regions, but maybe that is as its supposed to be if you think in terms of classical art and draw shadows in terms of each light obstruction.

• Linux halts every few seconds

  - by Zeppomedio

  We're having an issue where one our Linux boxes (Ubuntu 10.04 LTS, running on EC2 with a quadruple-large size, 68GB of RAM and 8 virtual cores with 3.25GHz each) freezes up every few seconds. Typing in an ssh session will freeze, and running strace on one of the Postgresql processes that's running usually shows: 02:37:41.567990 semop(7831581, {{3, -1, 0}}, 1 for a few seconds before it proceeds (it always gets stuck at that semop). OProfile shows that most of the time is spent in the kernel (60%) versus 37% in Postgresql. The result of these halts (which began suddenly a day ago) is that load on the box has gone from 0.7 to 10+, and causes our entire stack to slow done. Any ideas on how to track down what's going on? iostat doesn't show the disks being particularly slow or overloaded, and top shows user cpu % spike from 8% to about 40% whenever these back-ups happen.
