  • How do I stop Sophos anti virus from scanning directories that are under source control

    - by user26453
    From googling it seems its well known that SophosAV as well as other AV programs have issues with how they interact and can inhibit source control utilities like TortoiseHG or TortoiseSVN. One solution is to exclude directories under source control from on-access scanning as detailed here on Sophos's support site. There is a corollary article that mentions some issues related to this, namely the need to place multiple entries for exclusions based on the possibility of the location being accessed through the short vs. long name (e.g., Progra~1 vs. "Program Files"). One other twist is I am using a junction to relocate my user directory, C:\Users\Username, to a second hard drive, E:. Since I am not sure how this interacts I have included the source control directory as they are nested in both locations. As a result, I have included the two exclusions for the on-access scanning exclusions (and to be on the safe side on-demand exclusions as well, although this should only come into play when I select a parent directory of the exclusion to be scanned on-demand, but still). You'll notice I have no need to add extra exclusions for those locations based on short vs. long name distinctions. The two exclusion I have then, for both on-access and on-demand scanning exclusions are: C:\Users\Username\source-control-directory E:\source-control-directory However, this does not seem to work as TortoiseHG still lags terribly in response to any request as AV software starts scanning when the directory is accessed via TortoiseHG. I can verify without a doubt that Sophos is causing the problems: I can completely disable on-access scanning. Once this is done TortoiseHG responds very fast to all operations. I cannot leave this disabled obviously, but since the exclusion don't seem to be working, what next?

  • Postfix Send Error: Must Issue STARTTLS command

    - by Mary Elizabeth
    Running Ubuntu 12.04 and trying to configure postfix to relay send and receive through GMAIL. Am running into connection issues particularly with TLS.

  • How to actually defragment a JFFS2 filesystem

    - by Julie in Austin
    I have searched all over the Internet, including on a number of StackExchange forums, for a workable method for defragmenting a JFFS2 filesystem and cannot find an answer. The system in question has a 256MB NAND flash part. It is being accessed as a MTD device which is divided into three partitions. The third partition is where the root file system is being stored as a JFFS2 file system. The issue is that writes to the root file system have non-deterministic performance due to the usual issues of the JFFS2 garbage collector deciding to run at the worst possible times. When that happens, the product is hung for some unknown length of time while the garbage collector (and pdflush) run. Changing the file system isn't an option. The solution needs to be something that can run during off-hours that after having been run results in more predictable write performance. Right now I am working on a program that will attempt to force the garbage collector to run, then delete the file with the hope that all of the freed nodes are suddenly more readily available and make writes perform better. Thoughts?

  • Reverse Proxies and AJAX

    - by osij2is
    A client of ours is using IBM/Tivoli WebSEAL, a reverse-proxy server for some of their internal users. Our web application (ASP.NET 2.0) and is a fairly straightforward web/database application. Currently, our client users that are going through the WebSEAL proxy are having problems with a .NET 3rd party control. Users who are not going through the proxy have no issues. The 3rd party control is nothing more than an AJAX dynamic tree that on each click requests all the nodes for each leaf. Now our clients claim that once users click on a node in the control, the control itself freezes in such a way that they don't see anything populate. Users see "Loading..." message appear but no new activity there afterwards. They have to leave the page and go back to the original page in order to view the new nodes. I've never worked with a reverse proxy before so I have googled quite a bit on the subject even found an article on SF. IBM/Tivoli has mentioned this issue before but this is about all they mention at all. While the IBM doc is very helpful, all of our AJAX is from the 3rd party control. I've tried troubleshooting using Firebug but by not being behind the reverse proxy, I'm unable to truly replicate the problem. My question is: does anyone have experience with reverse proxies and issues with AJAX sites? How can I go about proving what the exact issue is? Currently we're negotiating remote access so assume for the greater part that I will have access to a machine that's using the WebSEAL proxy. P.S. I realize this question might teeter on the StackOverFlow/ServerFault jurisdictional debate, but I'm trying to investigate from the systems perspective. I have no experience with reverse proxies (and I'm unclear on the benefits) and little with forwarding proxies.

  • cPanel web servers mounting home partition to a NAS or SAN

    - by Scott
    Hello, I currently have 2 cPanel web servers that are little 1RU dual cpu quad core xeons. They have a lot of resources for processing and handling web requests, and never exceed more than 10% cpu usage. They also have plenty of RAM. The problem is though that they both have RAID 1 160Gb SAS hard disk drives in them that are 75% full, and growing by the day. I didnt think that the amount of disk usage would be so high, but due to the nature of the sites hosted, this has become an issue. The easy fix would be just to upgrade the hard drives to something bigger (probably not of the SAS variety), but I am thinking of keeping the current machines as "processing servers" and buying a central "storage server" with about 12TB of storage. The /home/ partition on each of the 1RU servers would be mounted to a NAS or SAN point on this central storage server. My questions are: - Has anyone got a cPanel setup where they mount /home/ to a NAS or SAN elsewhere? If so, can you provide details as to what you did and how it went :) - Any recommendations on networking? Is gigabit ethernet enough? Is TCP/IP going to be a noticable performance problem? Anyone used a TOE key? - Anyone benchmarked or had any performance issues with SAN over NAS? Any help greatly appreciated. Scott

  • Is anyone using KVM in production?

    - by Andy Shellam
    I've been trying to set up a pair of servers utilising KVM on Ubuntu 9.10 to host 8 virtual machines between them and ended up with various issues from the VMs freezing, to not powering on. I had one virtual server set up and running and was setting up a second, when any operation involving OpenSSL would cause the VM to lock up in a weird way - all network traffic would cease, it wouldn't process logins on the console, but it wasn't taking any CPU time off the host. The first virtual server was identical and worked perfectly. Another VM I tried to setup had installed Ubuntu fine then refused to reboot, throwing kernel exceptions to do with XFS. I've now installed Citrix XenServer 5.5 on both hosts, and am now setting up my third VM with absolutely no issues. I also had the same experience when I tried VMware, but I preferred Xen as it appears to give more features on the free license. My question is am I just unlucky with KVM, or is KVM as unstable as it appears? Are you using, or planning on using, KVM in production, and how successful have you been?

  • Antivirus Configuration for dedicated SQL and dedicated IIS Servers

    - by Wayne Arthurton
    Our corporate standard is McAfee Enterprise, unfortunately this is non-negotiable. On two types of servers I'm responsible for, SQL & Web, we have noticed major performance issues with the corporate standard setup. Max scan time 45sec One policy for all processes Scan ALL files on write, read and open for backup Heuristics: Find unknown programs, trojans and macros Detect unwanted programs Exclude: EVT, LDF, LOG, MDF, VMD, , windows file protection) This of course still causes major slowdowns. IIS .NET recompiles are slow especially with SharePoint, SQL backups and restores, SQL Analysis Services, Integration Services and temp data from them as well. I have looked from time to time, for some best practices on setting up McAfee of SQL & SQL Analysis Service, SQL Integration Service, Visual Studio, Sharepoint, and .NET web servers in general. How do people setup McAfee enterprise on their corporate serves keeping security intact, but affecting performance as minimally as possible? Has anyone run across white papers on these setups? Obviously some are case by case, but there must be some best practices out there somewhere.

  • Dell Management Packs in System Center Operations Manager 2007 R2?

    - by bwerks
    Hey all, I recently set up SCOM in a small business network environment. The root management server is a Dell Poweredge 2950, and I'd like to use SCOM to monitor it using Dell's management packs. I've imported the management packs into the SCOM deployment and followed Dell's installation instructions, but it doesn't seem to be fully working yet. Currently, the Diagram views in the Dell tree (Monitoring tab) seem to show me the server's place in the network topology, so it seems that at least part of it is working. However, none of the reports under "Performance and Power Monitoring Views" provide any information. When clicking on one of them (Power Consumption (Watts), for instance), the display area is blank and there is a tooltip visible that reads "No performance counter is selected. To select a counter, place a check mark in the Show column in legend below." However, in the legend, there's nothing there for me to check. I've installed OpenManage 6.2 on the server as per the Dell documentation, but I don't know what else I could have done that I missed. Does this sound like a familiar problem to anyone?

  • zfs setup question

    - by Staale
    Currently I have a linux storage box and server with 4x750gb harddrives in raid-5 with ext3. I have ordered 3x1.5tb disks to upgrade this. Here is my planned upgrade: Backup: Format the 1.5 tb disks Copy all data from the raid-5 disks to the 1.5tb disks Destroy the raid-5 array. New setup: Create a VirtualBox system and install Nexenta (OpenSolaris + ubuntu) on it. Create a zfs pool with zraid1 with the 4 750gb disks. Copy from 1.5tb disks to the virtualbox zfs pool Format the 1.5tb disks. Replace 3 off the 750gb disks with 1.5tb disks. Reuse the 750gb disks elsewhere. The reason I wish to use one 750gb disk is since I can't grow the disk count in a raidz array, and this gives me the option off replacing that disk later for an extra 750gb storage. Would the ZFS performance be good running through virtualbox? Or will the performance overhead be too large? Will I get 1.5tb+1.5tb+750gb storage on the zraid? Or just 750gbx3 until all disks are 1.5tb?

  • Developer's PC - worth getting more than 8GB RAM?

    - by Borek
    I'm building a developer PC and am wondering whether to get 8GB or 12GB. It's a Core-i7 860 system, i.e., 1156 motherboards with 4 slots for RAM sticks, dual channel, usually up 16GB (as opposed to 1366 sockets where 6 banks / triple-channel are used). 8GB would be cheaper to get especially because price per GB is lower with 4x2GB compared to 2x4GB. Also the availability is worse for 4GB DIMMs here where I live; those are the main practical advantages of 8GB. (Edit: I should have stressed the price difference more - in the eshop I'm buying from, the difference between 12GB and 8GB is so big that I could almost buy a whole new netbook for it.) However, I understand that more RAM can never do harm which is the point of this question - how much of a difference will 12GB make as opposed to 8GB? Honestly, I've always been on 3.2GB systems (4GB but 32bit system) and never felt much pain from having too little memory - of course there could be more but for instance compiler's performance was usually held back by slow I/O or not utilizing multiple cores on my CPU. Still, I'm not questioning that 8GB will be useful, however, I'm not sure about the additional 4GB difference between 8 and 12 gig. Anyone has experience with 8GB / 12GB systems? The software I usually run all the time: Visual Studio or Eclipse (both should be fine with ~2GB RAM, after that I feel their performance is I/O bound) Firefox (it can never have enough RAM can it? :) Office (~500MB RAM should be enough) ... and then some smaller apps like Skype, other browsers, some background services etc.

  • rr.com appended to URL and I don't know why

    - by Steph
    I've been having some pretty bad and intermittent internet connectivity issues. I keep getting timeouts on my browsers, or what appears to be timeouts on my browsers. In Chrome it's generally error 21. FF it times out. And so on. While this is happening, I can go into the command line and ping or traceroute the same domain and it works fine. I use my cellphone on the same network and it's fine connecting to the same domain. And when it fails, it's all domains that are down in all browsers, chrome, FF, etc. I also noticed that when I try to connect to 192.168.1.1 it says in chrome did you mean www.192.168.1.1rr.com but when I enter https://192.168.1.1 it's fine. It only seems to do this in Chrome. This is making me think I have a virus. I did some researching about something called road runner, but I can't find any related traces. I also ran a full virus scan using nod32 (eset) and nothing. Any suggestion or help would be greatly appreciated. The intermittent loss of total internet access is really annoying and I'm worried about why it's trying to append the rr.com domain in Chrome. I suspect I'm dealing with two different issues, but you never know. Also for the DNS I'm using Google's DNS servers, the famous 8.8.8.8 and 8.8.8.4

  • Why does bash sometimes think my $HOME isn't the correct directory?

    - by Adam Yanalunas
    Like the title says it seems that bash sometimes misidentifies my $HOME. This cropped up after a seemingly unique series of events that I will now replay in broad strokes. Running OS X 10.6 with normal, local account Work binds my account to Active Directory Much time passes with no issues Set up rvm to manage Ruby installs (this becomes important later) Upgraded to OS X 10.7 a few days ago After successful install, attempted to log in, was presented with "Must reset password" dialog that never allowed a password to be reset. Would simply shake the box after new password was entered. Much googling was done. Much more googling was done. Swearing was had. Logged in as root, created new account, set as admin, deleted /Users/[new account], renamed /Users/[old account] to /Users/[new account] Logged out of root, logged into new account with no issues After OS X asking for a my account password a few times to update Keychain and other system-level stuff it was back to business as usual. Opened Terminal, cd to project folder, tried "rails server" and was presented with: /usr/local/lib/ruby/1.9.1/rubygems/dependency.rb:247:in to_specs': Could not find rails (>= 0) amongst [] (Gem::LoadError) from /usr/local/lib/ruby/1.9.1/rubygems/dependency.rb:256:into_spec' from /usr/local/lib/ruby/1.9.1/rubygems.rb:1210:in gem' from /usr/local/bin/rails:18:in' Ran through a few exercises, decided to rm -rf ~/.rvm and reinstall. Running a --trace on the rvm installer shows it dies on this line: mkdir: /Users/[old account]: Permission denied Scrolling back through the --trace log I see many more mentions of /Users/[old account]. When inspect the install script the offending line is looking at "${HOME}/.rvm" as it tries to run the mkdir. To my confusion I also see mentions of /Users/[new account] in the log. I've tried exporting a new HOME in my .bash_profile to no luck. Can anyone guess why /Users/[old account] would still be kicking around?

  • How to stop SophosAV from scanning directories under source control

    - by user26453
    From googling it seems its well known that SophosAV as well as other AV programs have issues with how they interact and can inhibit source control utilities like TortoiseHG or TortoiseSVN. One solution is to exclude directories under source control from on-access scanning as detailed here on Sophos's support site. There is a corollary article that mentions some issues related to this, namely need to place multiple entries for exclusions based on the possibility of the location being accessed through the short vs. long name (e.g., Progra~1 vs. "Program Files"). One other twist is I am using a junction to relocate my user directory, C:\Users\Username, to a second hard drive, E:. Since I am not sure how this interacts I have included the source control directory as they are nested in both locations. As a result, I have included the two exclusions for the on-access scanning exclusions (and to be on the safe side on-demand exclusions as well, although this should only come into play when I select a parent directory of the exclusion to be scanned on-demand, but still). You'll notice I have no need to add extra exclusions for those locations based on short vs. long name distinctions. The two exclusion I have then, for both on-access and on-demand scanning exclusions are: C:\Users\Username\source-control-directory E:\source-control-directory However, this does not seem to work as TortoiseHG still lags terribly in response to any request as AV software starts scanning when the directory is accessed via TortoiseHG. I can verify without a doubt that Sophos is causing the problems: I can completely disable on-access scanning. Once this is done TortoiseHG responds very fast to all operations. I cannot leave this disabled obviously, but since the exclusion don't seem to be working, what next?

  • Need a new mouse: clicky scroll wheel and additional thumb-operated scroll wheel

    - by cksubs
    I'm having some carpel tunnel syndrome or RSI issues, and I need to get a new mouse. I've tried a friend's Logitech MX Revolution and it's almost perfect. I LOVE the thumb-operated scroll wheel, and I think that that alone would solve many of my hand pain issues. The problem is that it uses their newfangled smooth/click scroll wheel. It can be either smooth or clicky, and is switched by pressing in the scroll wheel. I really question Logitech's user research on that one. I've been using middle-click to open new links and close tabs for years now in my browser, and I'm not willing to give that up for this cool technology. In fact I HATE smooth scroll wheels in general, and need a clicky one. The option would be ok, but not if it's activated via the middle-click button. In closing, I'm looking for these items in my mouse: Thumb-operated scroll wheel or 'joystick'-like apparatus. Clicky, as-stiff-as-possible scroll wheel on top Normal middle-click functionality. Comfortable, preferably ergonomic design. Anyone have any suggestions? Logitech, want to get rid of that smoothing-scrolling crap so I can buy your mouse?

  • Laptop choice for development: MacBook Pro 17 vs Dell Studio XPS 16 vs HP Envy 15

    - by Shalan
    Hey! First things first - let me state that I am not intending to play games on this - I have narrowed down to these 3 purely based on specs and its individual brand reliability in the market. I intend to primarily use: Visual Studio 2008 Pro a lot (develop and deploy on Windows platforms) SQL Server 2005 Oracle 10g Adobe Photoshop CS4 Microsoft Expression Studio Google Sketchup I currently use a desktop PC (Core2Duo 2.66Ghz with 3GB DDRII memory) running Vista Business 32-bit - and I have to admit that, especially for Visual Studio, its quite sluggish to a point where it affects productivity. Furthermore, I intend to only use the notebook on a table - with a cooled surface, like granite :) - so I would appreciate people's input with regard to heat issues. Im aware that the Dell's primary exhaust gets blocked by the lid when open, but some reviews don't seem to place extraordinary emphasis on heat issues resulting from this. My options for the Dell/Alienware: Core i7 720QM 4GB DDRIII memory ATI mobility 3670 (512) 128GB Solid State Drive 16-inch Full HD RGB-LED LCD display (1080p) 3-year next-business-day support My configuration for the Apple MBP: Core2Duo 2.8Ghz (Im assuming the T9600) 4GB DDRIII memory 128GB Solid State Drive standard 1 year support The one advantage I think of with the MBP is that I can have the addition of OSX (though Im unsure what I would use it for, but purely to play around with a much-boasted-about OS) What are your thoughts on this, especially regarding build-quality, heat, performance and battery-life? Much thanks! ~shalan

  • IIS serving static content gives 503 at random

    - by Steffen
    We're having a few issues with our image server. It's a Win 2008 running IIS 7.5 and it only serves static content: images. It has run without issues for quite a while, until recently when we disabled Output Caching, as we noticed having it enabled meant it sent no-cache host-headers to the clients (forcing them to fetch the images from the server every time) We've read quite a bit about it, and it seems IIS just works that way - either you use Output Caching or you get to use cache host-headers. Anyway having disabled the Output Cache, we now experience random 5 minutes intervals, where all requests just get a 503 Service Unavailable. During this period the "Files cached" performance counter staggers (neither increased nor decreased) and after the period all caches are flushed. You might find it weird I talk about caching, since we disabled Output Caching. The thing is we changed the ObjectTTL parameter in registry, so we cache files for 3 minutes (which has worked very well, our Disk I/O dropped significantly) So even with Output Caching disabled, we're still caching plenty of files - if we could just get rid of the random 503 it'd be perfect :-D We don't get any messages in the Windows event log during these 503 intervals, so we're pretty stumped as to what to do. Any ideas are very welcome :-)

  • Problem while Installing mysql cluster

    - by Champion
    I downloaded latest mysql cluster file 64 bit (mysql-cluster-gpl-7.1.9-linux-x86_64-glibc23) from mysql site. Ran following command to install mysql server. /home/mysql_cluster/mysqlc/scripts/mysql_install_db --no-defaults --basedir=/home/mysql_cluster/mysqlc --datadir=/home/mysql_cluster/my_cluster/mysqld_data It's giving following issues. /home/mysql_cluster/mysqlc/scripts/mysql_install_db: line 245: /home/mysql_cluster/mysqlc/bin/my_print_defaults: No such file or directory Neither host 'db' nor 'localhost' could be looked up with /home/mysql_cluster/mysqlc/bin/resolveip Please configure the 'hostname' command to return a correct hostname. If you want to solve this at a later stage, restart this script with the --force option My host is pinging and hostname command gives correct hostname. I tried also with --force option force but still not working giving following issues: /home/mysql_cluster/mysqlc/scripts/mysql_install_db: line 245: /home/mysql_cluster/mysqlc/bin/my_print_defaults: No such file or directory Installing MySQL system tables... /home/mysql_cluster/mysqlc/scripts/mysql_install_db: line 393: /home/mysql_cluster/mysqlc/bin/mysqld: No such file or directory Installation of system tables failed! Examine the logs in /home/mysql_cluster/my_cluster/mysqld_data for more information. It says above files doesn't exist but this files are present checked with ls command. We are using XEN VM with 64 bit debian lenny os. How this issue can be resolved ?

  • On a dual-GPU laptop, is using the discrete GPU ever more power efficient?

    - by Mahmoud Al-Qudsi
    Given a laptop with a dual integrated/discrete GPU configuration, is it ever more power efficient to use the discrete GPU instead of the integrated? Obviously when writing an email or working on a spreadsheet, the integrated GPU will always use less power. But let's say you're doing something graphics-medium but not graphics-intensive/heavy - is there a point where it actually makes sense to fire up the discrete GPU, not for performance but for power-saving reasons? Off the top of my head, I can think of a scenario where the external GPU supports hardware decoding of a particular video codec - I'd imagine there is a "price point" where using the GPU saves more energy than decoding that fully in software would. But I think most GPUs, integrated or discrete, pretty much decode just the plain-Jane h264. But maybe there is something more complicated, perhaps if you're doing something like desktop/windowing animations or a flash animation on a website (not an embedded flash video) - maybe the discrete GPU will use enough less power to make up for switching to it? I guess this question can be summed up as to whether or not you can say beyond doubt that if you don't care for performance on a laptop with two GPUs, always use the integrated GPU for maximum battery life.
