• Sar data not collected for 10 minutes

  - by Ichorus

  We have a RedHat server whose only job is to run a JBoss server. Monitors said that memory usage spiked (we have the JVM limited to far less than the total memory on the system) and JBoss crashed. We restarted and everything seems ok now. Odd thing is that sar data for 10 min leading up to the crash is simply not there. Load average got up to the 50s. I have seen severely busy systems (350+ Load Average) still collect sar data. Does anyone have any idea what could cause sar to stop collecting data?

• Differences in memory consumption between two identical D7 sites?

  - by aendrew

  I'm running Drupal on a news site that has a lot of different View blocks on the front page (~5 total, all cached). In trying to reduce the memory footprint of the site, I've checked out source from SVN to a local development install to try and convert some of those blocks into more optimized code. Here's the weird thing. Devel module lists memory consumption at 50mb on the Production site (Running Nginx, PHP 5.2.17, XCache and Zend Optimizer.) but only 14mb on my development site (Running Apache2, PHP 5.2.13 and XCache). These are nearly-identical versions of the same site — frankly, the Production site should use even less memory as I've disabled some of the modules running on the Dev site. Any idea why this might be the case?

• How to add nvidia drivers after previous failure with linux mint?

  - by LessThanMe

  Before today, I had perfectly good drivers from nvidia for my linux mint (15) box. I decided to update it because my performance in TF2 is less than stellar, and then things went south. I used synaptic to install nvidia-331 and then rebooted, but when I selected Mint in GRUB I waited...and waited...and waited. Nothing happened, but the display stayed on (a completely black video was being output). So I went into recovery mode from GRUB, went to root access, and apt-get remove --purge nvidia*'d my way out of that mess, and installed nvidia-common. Now my performance in graphic intensive stuff (read: games, blender) sucks, so I've been through the same thing a few times trying to re-install nvidia-current. I just want to get it back how it was. Thanks for any help! Nvidia GTX 560

• Has anyones successfully configured mutt for GMail on FreeBSD? If so, how?

  - by Hank Gay

  I've tried following the instructions here and here. Currently, I can read email from my GMail account, but not send—this is on a personal computer, so even if I configured Sendmail, I doubt any of the mail would survive the spam filter gauntlet. Both guides seem to require the --enable-smtp option for mutt, which I don't think is being exposed by ports. I've tried the mutt and mutt-devel ports and neither seem to give me that option. On a far less important note, I also haven't been able to change folders, e.g., I get told that Sent Mail is not a valid folder when I attempt to go into it. If you can troubleshoot this problem, it's pure gravy. I really only care about sending. Thanks, Hank

• How to back up server with rsync, preserving ownership/permissions without root login

  - by olilarkin

  I am setting up a backup server on which I want to run rsync over ssh to backup content on other servers every night. I would like to set up ssh keys to make it password-less, but I want to preserve ownership of files and permissions. There are a number of users on the server to be backed up which won't all exist on the backup server. What would be the best way to do this? I guess the backup job will need to connect as root to , but I don't want to enable root ssh access on the servers. thanks for any tips, oli ps, all servers are running UBUNTU Server 12.04 LTS and are behind a university firewall.

• How would I `wget` files and then save them by date downloaded rather than filename?

  - by searchfgold6789

  My goal: To download 131 JPEGs and save them in a file name format that is relative to the date/time format rather than their file name. I have already tried things that involve changing the files' names after they have already been downloaded. However, these methods do not work because it seems like exif data is not being kept. For example: jhead -n%Y%m%d-%H%M%S *.jpg just returns a bunch of errors saying: Possible new names for for '{filename}.jpg' already exist File '{filename}.jpg' contains no exif date stamp. Using file date Usually, as in this case, I wind up with less files than I started out with. So is there some command I can pass to wget instead? I have already tried the --timestamp option with no success. (The man page is not to clear about what that does.)

• Messages don't always appear in Mail.app

  - by MikeHoss

  My wife and I share a Mac and use different accounts. We both use Apple's standard Mail.app. We can also get to our email accounts via SquirrelMail that our webhost provides. Both SquirrelMail and Mail.app are connecting via IMAP. My wife was the first to notice that not all messages were getting to the Mail.app. She would check the Mac (our main machine) and then a little while later check mail from another machine via SquirrelMail and see messages there that should have been on the Mac. She would go back and those messages would never show up. Lately, I have been seeing the same thing, though less often. I can't reproduce it, or just look at a message to see if they haven't been moved over. I've looked in Junk, etc. and the Mac simply never sees those messages via IMAP. Does anyone have a guess to something I could poke around at?

• Paste a list of dates in format of "mm/dd/yy" to iWork-Numbers

  - by David.Chu.ca

  I have trouble to paste a list of strings in the format of 'mm/dd/yy' into iWork-Numbers. For example, I have a list of strings(text in VIM): 04/01/10 04/03/10 04/13/10 I copy those strings and then paste into my iWork-Numbers worksheet. The result will be: 2004-01-10 2004-03-10 04/13/10 It looks like that Numbers (mac workseet application in iWork) tries to convert the first two digits into year, then the next two into month if less than 12 and last two digits to a day, for the first two rows. For the third(04/13/10), since the middle two digits are 13 and cannot be a month, then this row is pasted as it is (actually it is what I need). Is there any way to paste whatever as they are, without any "smart date conversion"? Do I have to change settings in Numberers or Mac OS's System preference?

• Should I consolidate multiple identical VMs into BSD jails?

  - by Josh

  We run a number of Openfire XMPP/Jabber servers. Due to the way Openfire works, we cannot easily run multiple Openfire instances on one server, so I have 5 identical VMware ESXi VMs, each with CentOS, MySQl, Java, and Openfire. They're the exact same, except for their IP addresses, the actual Openfire MySQL database and it's config file. I am wondering if this is the optimal configuration, or if it would be better to move these VMs to a single FreeBSD machine and put each one inside a FreeBSD jail. Specifically, I am wondering if the benefit of VMWare's Transparent Page Sharing (TPS) would outweight the cost of running 5 identical OSes. Would I end up using less memory with one large FreeBSD machine and java running in bsd jails?

• How can I do `dir *.mp3` in bash?

  - by Andy

  Hi all, On Windows I used to quickly run a dir *.mp3 to find all files with an mp3 extension in the current directory. Is there a similarly quick way to do it with bash? The ls command seems to have a way to ignore a pattern, but not to show only the pattern. I can do find . -maxdepth 1 -iname '*.mp3' or ls|grep -i '\.mp3$' but neither of these flow out of my fingers in half a second or less;) Any quicker alternatives? TIA Andy

• High CPU usage on Linux machine

  - by user305210

  I have a piece of java code running on two different machines, but on one of the linux machines, the code uses alot of CPU (close to 100% cpu usage). On the other machine the same code uses less cpu (under 3 to 4%). The machine where cpu usage is high, is a more powerful machine, more CPU and and more memory. This has started happening recently and performance on the machine with high cpu usage has degraded significantly. I am wondering if anyone has any ideas why something like this could happen, possible causes behind this etc. any guesses? No recent changes in hardware were made, no recent code updates... Thank you.

• Epson XP-600 will not print properly with all new ink recently installed

  - by Joy

  I just installed brand new Epson 273 ink cartridges ($64 worth!) in my Epson XP-600 printer. One box had all the colors plus black, and one had the fatter black cartridge. I am not getting ANY black print on paper, although, when I lift the cartridges out, they show ink inside. Now the yellow is saying LOW though all cartridges are less than 2 weeks old. I only use this printer sparingly—not for business or work reasons. I am ready to scream, as the ink cost almost as much as the actual printer (which is barely 7 months old)! Any ideas on how to solve this issue?

• Why did my power supply fry itself?

  - by ULTRA_POROV

  I am in europe. There was a switch on my psu that could switch the voltage between 230v and 130v (not 100% sure). In europe we use 230. I switched the psu to 110 and turned it on. Several sparks and a power failiure resulted, the psu was fried. Can someone explain why this happened. I was assuming that because the system was using 230 and the psu only draws 130 it would be safe cause it's less. I guess i was wrong. Can someone explain me the physics behind this.

• Connection to SQL Server 2008 R2 Database Server is SLOW

  - by AbeP

  The database server is a VM running SQL Server 2008 R2 on top of Windows Server 2012, 24GB RAM allocated and 2TB of disk space. Overall, the database connections are very slow and one thing that stands out is that the connection to the database server via SSMS takes 5-10 seconds. On other much less powerful servers, it takes 1-2 seconds. The VM is technically way more powerful than other machines, but the connection to the server is too slow. So, my guess is the issue is network related, but any clues on where I should be looking? Thanks!

• How does NTFS compression affect performance?

  - by DragonLord

  I've heard that NTFS compression can reduce performance due to extra CPU usage, but I've read reports that it may actually increase performance because of reduced disk reads. How exactly does NTFS compression affect system performance? Notes: I'm running a laptop with a 5400 RPM hard drive, and many of the things I do on it are I/O bound. The processor is a AMD Phenom II with four cores running at 2.0 GHz. The system is defragmented regularly using UltraDefrag. The workload is mixed read-write, with reads occurring somewhat more often than writes. The files to be compressed include personal documents and selected programs, including several (less demanding) games and Visual Studio (which tends to be I/O bound more often than not).

• Hosted Kerio Mailserver vs. Hosted Exchange

  - by Dayton Brown

  Hi all, I'm in the beginning stages of migrating from an internal exchange server (2003) to external hosted services. We don't have a huge user base, less than 100, but we need to support BlackBerries, iPhones, Outlook RPC/HTTP, etc. I really like exchange hosted providers (I've used intermedia in the past) but pricing is a bit high. Does anyone have any experience with Kerio? It looks great, but I'd like to hear some unbiased opinions. Or biased if you are really happy working for a particular hosting company ;-)

• What is the most economic hardware that will run Ubuntu? [closed]

  - by nbolton

  I'm looking to buy the cheapest hardware I can find that will run the latest version of Ubuntu desktop on some sort of usable level (e.g. use of web browser, flash, etc). I guess small form factor would be pretty convenient, so I was looking at Acer Aspire Revo for example, but I'm not sure whether or not it's overpriced. I'd rather pay less for the same thing minus brand name if it's available. Any ideas? On further investigation, it seems I'm looking for a nettop.

• Database server: Small quick RAM or large slow RAM?

  - by Josh Smeaton

  We are currently designing our new database servers, and have come up with a trade off I'm not entirely sure of how to answer. These are our options: 48GB 1333MHz, or 96GB 1066MHz. My thinking is that RAM should be plentiful for a Database Server (we have plenty and plenty of data, and some very large queries) rather than as quick as it could be. Apparently we can't get 16GB chips at 1333MHz, hence the choices above. So, should we get lots of slower RAM, or less faster RAM? Extra Info: Number of DIMM Slots Available: 6 Servers: Dell Blades CPU: 6 core (only single socket due to Oracle licensing).

• Probability of failure with larger number of network elements

  - by MikeKulls

  I'm having a discussion with a work colleague. I'm saying that a network with 100 elements will have pretty much 10 times as many failures as a network with 10 elements, ie a tech will need to replace faulty hardware 10 times more often. He suggests that the failure rate doesn't go up in a linear fashion and the failure rate will be significantly less than 10x, in fact only slightly more failures. This is not the probability of an outage etc, we are just talking in relation to the amount of parts that a tech would need to swap out in a given time frame.

• Reduce the I/O priority of Windows Backup (Windows Server 2008 R2)

  - by HelloSam

  I have a PostgreSQL running on Windows Server 2008 R2 x64 box. And I have scheduled a backup everyday from the RAID 1 DB disk to a dedicated standalone disk. They are SAS 15k on Dell PERC 6i. I am using the built-in Windows Server Backup for purpose. The problem is, whenever the backup process is kicked in, the database performance is hogged. I would say almost a 10x of performance reduction. From the resource monitor, the disk queue is in the double digit range when backing up, and less than 1 during the day. The disk activity is like ~30-50MB/s during backup, so I guess the hardware is acting normally, though wbengine.exe takes up most of the portions. I think reduce the IO priority of the backup process would be an answer, but I couldn't find a way to. Tuning process CPU priority does not seems to help.

• Getting back the old alt-tab windows switching behavior in Windows 7?

  - by Carlos A. Ibarra

  When you run more than 6 applications on Windows 7 and you press alt-TAB, icons representing the first 6 applications and the desktop appear on the first row of the grid and you can cycle with alt-TAB-TAB... through the 6 most recently used windows the usual way, but the 7th and other less recently used windows don't follow the same rules. Instead they get grouped together according to their application but disregarding whether they were recently used or not. This new behavior is mentioned here. I am very used to the old way of cycling and the new system is driving me crazy. I tend to have 20 or so windows open at one time and I frequently need to alt-tab to the 7th or 8th window on the stack but it doesn't work the same anymore. Does anyone know how to put back the old behavior, so that alt-tab-tab-tab... goes through the whole list in most-recent to least-recent order?

• Good reasons to keep 32-bit Microsoft Windows desktop OSes

  - by Mark Henderson

  Server software has been 64-bit only for a while now (Since Server 2008 R2 for Windows, even earlier for Exchange and Sharepoint) and even Ubuntu are pushing you away from 32-bit versions for their server OSes. But is there any good, quantifiable reason to keep a 32-bit desktop operating system maintained? We're preparing our Windows 8 images for the (unfortunate?) few that will be early adopters. The majority of our desktop computers have 4gb or less of RAM, but I would love to not have to bother supporting a 32-bit flavoured operating system any more. Any reason why I should?

• Mapping of memory addresses to physical modules in Windows XP

  - by Josef Grahn

  I plan to run 32-bit Windows XP on a workstation with dual processors, based on Intel's Nehalem microarchitecture, and triple channel RAM. Even though XP is limited to 4 GB of RAM, my understanding is that it will function with more than 4 GB installed, but will only expose 4 GB (or slightly less). My question is: Assuming that 6 GB of RAM is installed in six 1 GB modules, which physical 4 GB will Windows actually map into its address space? In particular: Will it use all six 1 GB modules, taking advantage of all memory channels? (My guess is yes, and that the mapping to individual modules within a group happens in hardware.) Will it map 2 GB of address space to each of the two NUMA nodes (as each processor has it's own memory interface), or will one processor get fast access to 3 GB of RAM, while the other only has 1 GB? Thanks!

• GNU screen configuration for optimal keycode recognition

  - by intuited

  Currently GNU screen will botch up certain keystrokes, for example CTRL pressed in combination with the arrow keys, so that eg when in vim insert mode, CTRL-PGUp will Uppercase the next/current word (or something like that). I'd like for it to work pretty much transparently, so that the functionality is the same as when it's not running (with the obvious exception of CTRL-a control sequences)... is this possible? Also — and I suspect this is more or less a separate issue — I'd like for the scrollwheel to scroll back in the session log rather than cycling through the history as it does now. Doable? Or perhaps it could be set to emulate a much larger screen size that the terminal app that it's running under could keep that text in its session log. either way the goal would be to be able to use the mouse wheel and/or shift-up-arrow to scroll back in the session log.

• What's the simplest configuration of SVN on a Windows Server to avoid plain text password storage?

  - by detly

  I have an SVN 1.6 server running on a Windows Server 2003 machine, served via CollabNet's svnserve running as a service (using the svn protocol). I would like to avoid storing passwords in plain text on the server. Unfortunately, the default configuration and SASL with DIGEST-MD5 both require plain text password storage. What is the simplest possible way to avoid storing passwords in plain text? My constraints are: Path-based access control to the SVN repository needs to be possible (currently I can use an authz file). As far as I know, this is more-or-less independent of the authentication method. Active directory is available, but it's not just domain-connected windows machines that need to authenticate: workgroup PCs, Linux PCs and software that uses PySVN to perform SVN operations all need to be able to access the repositories. Upgrading the SVN server is feasible, as is installing additional software.
