• Windows Photo Viewer needs more ram?

  - by Aren B

  Ok, so i went to open a picture with the Windows Photo Viewer (Default) application and it told me this: Windows Photo Viewer can't display this picture because there might not be enough memory available on your computer. Close some programs that you aren't using or free some hard disk space (if it's almost full), and then try again. So looking at my 98% ram usage (thankyou VisualStudio x8 + SQL Server) I rebooted my computer. Now this is my load: And this is my hard-disk loadout: So now I go to load up that image again. SAME MESSAGE, what the heck? So apparantly 6gb isn't enough ram to open a 29k image that loads perfectly fine in MSPaint, Paint.NET, Photoshop It's a .png and it's not corrupt. So my question is: what gives?

• IIS 401.3 - Unauthorized on only 1 server out of 3 set up for network load balancing

  - by Tony

  Over the weekend our Server Admin set up two virtual Windows 2008 machines with IIS installed and set them up under NLB. I came in and changed the application pool the website was running under to our domain account that has proper access to the database and the file share hosting our .NET web application Sitefinity, and changed it to .NET 4 Integrated. NLB and everything was running fine on both servers. He brought up the third server for our cluster on Tuesday and I performed the same actions.. The only difference was that I was given admin rights for the third server so I could set it up remotely instead of going to his office. He has full control over the share and NTFS perms on \\hostname\Sitefinity and I believe I only had read access. I pointed the web site to the same \\hostname\Sitefinity\sitename share that the others were on and the authentication/authorization test settings passed. I hit the site from http://localhost (like I did successfully from the other two before trying the cluster's IP address) and I received a HTTP Error 401.3 - Unauthorized. I've verified many times that the application pool is running under the same service account. I tried hitting just a simple test.htm.. works fine on both of the first two servers but I get the same 401.3 on the third. I copied my dev project to the local inetpub directory and re-pointed the website and that ran perfectly. I turned on Failed Request Tracing and it acts like it's still running the local IUSR account I guess (instead of my domain account)? Here is an excerpt of the File Cache Access Start and the error from the trace: FileName \\hostname\sitefinity\sitename\test.htm UserName IUSR DomainName NT AUTHORITY ---------- Successful false FileFromCache false FileAddedToCache false FileDirmoned true LastModCheckErrorIgnored true ErrorCode 2147942405 LastModifiedTime ErrorCode Access is denied. (0x80070005) ---------- ModuleName IIS Web Core Notification 2 HttpStatus 401 HttpReason Unauthorized HttpSubStatus 3 ErrorCode 2147942405 ConfigExceptionInfo Notification AUTHENTICATE_REQUEST ErrorCode Access is denied. (0x80070005) ---------- My personal AD account was then granted read/write perms to the share so I created a new application pool and set the site under it in case there was an issue with the application pool but no success. I created another under my own account and it still failed. It just seems like maybe it's not trying to access the files under the account my application pools are running under although that's the only way I've done things before. I set the Physicial Path Credentials in Advanced Settings on the site to the service account and it threw a 500 error of some sort so I assume that's not the answer (and I don't have to do it on the other servers). It's like somehow I'm trying to force impersonation on the IUSR account or something?

• Appears to be "randomly" switching between the acl matched backend and the default backend

  - by Xoor

  I have HAProxy acting as a proxy in front of: An NGinx instance An in-house load balancer in front of multiple dynamic services exposed with socket.io (websockets) My problem is that from time to time my connections are proxied correctly to my socket.io cluster, and then randomly it fallsback to routing to NGinx which obviously is annoying and meaningless since NGinx isn't mean't to handle the request. This happens when requesting for URLs of the format : http://mydomain.com/backends/* There's an ACL in the HAProxy config to match the '/backends/*' path. Here's a simplified version of my HAProxy config (removed extra unrelated entries and changed names): global daemon maxconn 4096 user haproxy group haproxy nbproc 4 defaults mode http timeout server 86400000 timeout connect 5000 log global #this frontend interface receives the incoming http requests frontend http-in mode http #process all requests made on port 80 bind *:80 #set a large timeout for websockets timeout client 86400000 # Default Backend default_backend www_backend # Loadfire (socket cluster) acl is_loadfire_backends path_beg /backends use_backend loadfire_backend if is_loadfire_backends # NGinx backend backend www_backend server www_nginx localhost:12346 maxconn 1024 # Loadfire backend backend loadfire_backend option forwardfor # This sets X-Forwarded-For option httpclose server loadfire localhost:7101 maxconn 2048 It's really quite confusing for me why the behaviour appears to be "random", since being hard to reproduce it's hard to debug. I appreciate any insight on this.

• Managing multiple Apache proxies simultaneously (mod_proxy_balancer)

  - by Hank

  The frontend of my web application is formed by currently two Apache reverse proxies, using mod_proxy_balancer to distribute traffic over a number of backend application servers. Both frontend reverse proxies, running on separate hosts, are accessible from the internet. DNS round robin distributes traffic over both. In the future, the number of reverse proxies is likely to grow, since the webapplication is very bandwidth-heavy. My question is: how do I keep the state of both reverse balancers / proxies in sync? For example, for maintenance purposes, I might want to reduce the load on one of the backend appservers. Currently I can do that by accessing the Balancer-Manager web form on each proxy, and change the distribution rules. But I have to do that on each proxy manually and make sure I enter the same stuff. Is it possible to "link" multiple instances of mod_proxy_balancer? Or is there a tool out there that connects to a number of instances, and updates all with the same information? Update: The tool should retrieve the runtime status and make runtime changes, just like the existing Balancer-Manager, only for a number of proxies - not just for one. Modification of configuration files is not what I'm interested in (as there are plenty tools for that).

• Firefox crash on first load on Ubuntu Linux on older Dell Laptop

  - by Ira Baxter

  I've had a Dell Latitude laptop since about 2000 without managing to destroy it. A month ago the Windows 2000 system on it did something stupid to its file system and Windows was completely lost. No point in reinstalling Windows 2000, so I installed an Ubuntu Linux on the laptop. Everything seems normal (installed, rebooted, I can log in, run GnuChess, poke about). ... but ... when I attempt to launch Firefox from the top bar menu icon, I get a bunch of disk activity, the whirling cursor icon goes round a bit and then everything stops: disk, icon, mouse. Literally nothing happens for 5 minutes. Ubuntu is dead, as far as I can tell. A reboot, and I can repeat this reliably. So on the face of it, everything works but Firefox. That seems really strange. The only odd thing about this system when Firefox is booting is that while it has an Ethernet port (that worked fine under Windows), it isn't actually plugged into an Ethernet. As this is the first Firefox boot since the Ubuntu install, maybe Firefox mishandles Internet access? Why would that crash Ubuntu? (I need to go try the obvious experiment of plugging it in).

• X-ming, Ubuntu apps - getting the Ubuntu style/theme to load

  - by user5402

  I am running X-ming on Windows 7 and using putty to ssh into an Ubuntu system. On the Ubuntu system I use the command: $ gnome-terminal & to display a terminal back on the Windows box. When I do this I don't get the standard Ubuntu style, i.e. dark purple background, Mono font, solid cursor (which I've configured in the Gnome Control Center.) Instead I get a very plain style - white background, blinking cursor, very small font. However, if I run gnome-control-center and then click on, say, the Keyboard icon, the terminal window will be reconfigured with the Ubuntu style with my customizations (e.g. block cursor vs. blinking cursor.) Just starting one of the control applets seems to trigger this style change. My question is: How can I trigger this style change more directly - without having to launch the Gnome Control center and launching one of the configuration applets?

• Load balancing with one server and IIS7(.5)

  - by Lieven Cardoen

  Is it possible to configure loadbalancing on one server with IIS7? What I would like is to have three applications in IIS7 (sites). One site should forward the requests to the other two sites (loadbalanced). Problem is that at a customer of ours loadbalancing is used (with virtual servers). We on the other hand do not have (yet) a virtual environment and only one buildserver. (maybe using Application Request Routing module?)

• My profile won't load!

  - by blsub6

  I can get into my Windows Server 2008 R2 primary domain controller via remote desktop just fine. It's my boss who's got his profile messed up. When he tries to log in, he gets the message The User Profile service failed the logon. User profile cannot be loaded. I've looked for his profile everywhere and cannot find it to delete or fix it. System Properties Advanced User Profiles shows my profile, the Administrator profile and the Default Profile. HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList only shows my profile and the Administrator profile. Everything that I've found on the internets points me to those locations. Help a brotha out?

• Apache heavy load VIRT vs RES memory

  - by pako

  I have a Debian 5 server, which gets a lot of traffic. Right now the server has 4 GB of RAM and no swap memory. I see in top that Apache processes consume roughly 180 MB virtual memory (VIRT) each, and 16 MB of real RAM (RES). So how many Apache threads can I have running at the same time? About 4 GB / 180 MB = 22 or 4 GB / 16 MB = 256?

• Is there a usable HTML web gallery template for Lightroom 2?

  - by Johannes Rössel

  The built-in HTML gallery unfortunately generates invalid HTML markup so its looks are likely more coincidence than proper design. That aside its JavaScript usage prevents using the middle mouse button to open an image in a new tab. A look at the few free HTML gallery templates out there shows me that there seems to be little interest in building an actual HTML gallery which doesn't use JavaScript. Most of them are using JS to build fancy animations or in-page popup boxes containing the image. This may be nice for some people but at least one person who looks at my images is on dial-up and quickly opening all images in individual tabs to let them load and then close the connection is very nice to have there. Anyone seen such a gallery template; i. e. simple, plain HTML without JS? My HTML/CSS skills aren't that good that I can develop such a thing on my own, unfortunately.

• CPU load, USB connection vs. NIC

  - by T.J. Crowder

  In general, and understanding the answer may vary by manufacturer and model (and driver, and...), in consumer-grade workstations with integrated NICs, does the NIC rely on the CPU for a lot of help (as is typically the case with a USB controller, for instance), or is it fairly intelligent and capable on its own (like, say, the typical Firewire controller)? Or is the question too general to answer? (If it matters, you can assume Linux.) Background: I'm looking at connecting a device (digital television capture) that will be delivering ~20-50 Mbit/sec of data to a somewhat under-powered workstation. I can get a USB 2 High-speed device, or a network-attached device, and am interested in avoiding impacting the CPU where possible. Obviously, if it's a 100Mbit NIC, that's roughly half its theoretical inbound bandwidth, whereas it's only roughly a tenth of the 480 Mbit/second the USB 2 "High Speed" interface. But if the latter requires a lot of CPU support and the former doesn't...

• Sony PMB causing failure to load Windows 7 Pro 64-bit normally or even Safe Mode

  - by Wesley

  After installing Sony's Picture Motion Browser on my desktop with Windows 7 Pro x64, it always goes to Startup Repair due to Windows 7 failing to start. This always happens after I try to install it. I've installed with all unnecessary programs closed and all disk drives and unnecessary usb ports empty. I don't exactly know what is causing the problem. Any ideas? My desktop is an HP m8530f. http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01469325&tmp_task=prodinfoCategory&lc=en&dlc=en&cc=us&product=3740333&lang=en Only upgrades are an HD4350 and a 500W PSU. EDIT: Windows 7 cannot start now. I'm currently running diagnostic tests from the BIOS. EDIT: Here are the problem details. Problem Signature: Problem Event Name: StartupRepairOffline Problem Signature 01: 6.1.7600.16385 Problem Signature 02: 6.1.7600.16385 Problem Signature 03: unknown Problem Signature 04: 21201022 Problem Signature 05: AutoFailover Problem Signature 06: 8 Problem Signature 07: CorruptFile OS Version: 6.1.7600.2.0.0.256.1 Local ID: 1033 CONCLUSION: So, I think Sony PMB may have caused some sort of corruption in the system files. So if you have Windows 7 and plan on installing Sony PMB, find a Vista or XP machine to install on.

• apache performance timing out

  - by Mike

  Im running a webserver where I'm hosting about 6-7 websites. Most of these websites get their content from MySQL which is hosted on the same server. Traffic average per day is about 500-600 unique visitors, about 150K hits per week. But for some reason sometimes websites send a timeout, OR sometimes websites dont load all images. I know that I should perhaps separate static content from dynamic content, but for now I think that's not a possibility. I would appreciate any suggestions on how could I improve the performance of apache, so it doesn't keep timing out.

• CS3, Illustrator - Where Do X/Y Coordinates Measure from?

  - by nicorellius

  I have a project where there are several PDF files. I'm using Illustrator to make these. It seems the point/line of origin is inconsistent from image to image (file to file). Where is the point of origin, by default, in CS3 Illustrator? It would be nice if, while I was positioning images, I could just say, "OK, x coordinate is 5.5 inches in this document, so it is 5.5 in that one." But it seems this is not the case. Anyone know how Illustrator sets these parameters?

• Cloning a USB flash drive to another larger one, is it safe to do so?

  - by Rob Kam

  I used Acronis True Image Home 2010 to clone a Dane-Elec zLight 8Gb pen drive/USB flash drive to a PNY Attaché 16Gb USB flash drive. Now WinXP shows the drive in device manager as USB DISK 2.0 USB DEVICE but doesn't have it in My Computer/doesn't assign it a drive letter. What is it that has messed up the PNY Attaché and is there some way to repair it so that it can be used as a regular USB flash drive again? Is there a safe way to clone a USB flash drive to another larger one? How safe is it to backup and restore a USB flash drive to/from a drive-image?

• Network card/driver stops under heavy load

  - by Uwe Keim

  Since about approx. 2 month, I do have the following issue with my approx. 1 year old development machine (Windows 7, 64 bit): When doing network intensive operations, like e.g. executing some SQL script on a remote SQL server to select or update 1000 of records, the network card stops working. I.e. suddenly, No network connection is present anymore. No internet, no local connection, simply nothing. The only resolution so far I found is to disable my network card and then simply enable it back, like in the following screenshots: 1.) Click "Deactivate" 2.) Click "Activate" (German screenshots only, sorry) Now this is an acceptable solution to work around this issue, but I would love to have this fixed, since it suddenly stops me from working when I'm connected remotely via VPN/RDP on my machine (Win7 64bit). So my question is: Could you imagine a possible cause for this issue and give some hints how to hunt/resolve it? I could imagine that this is a driver issue, a hardware issue or even some kind of background software issue like a software firewall or a virus scanner.

• Solaris 10: How to image a machine?

  - by nonot1

  I've got a Solaris 10 workstation that I'd like to create a full image backup from. The machine has 2 drives, one UFS for system root, and 1 ZFS for data storage. I intend to add a third HD to keep the backup images of both primary drives (including any zfs snapshots). The purpose is not disaster recovery, but rather to allow me to easily blow away a series of application installation/configuration changes I intend to try. What's the best way to do this? I'm not too familiar with Solaris, but have some basic Linux knowledge. I looked at CloneZilla, but it does not support Solaris. I'm OK with just a dd | gzip > image style solution, but I'd need some way to first zero-out the non-used blocks on the primary drives to aid gzip. They are are much larger than my 3rd drive, but hardly have any real data. Update to clarify: I specifically want to avoid using any file-system snapshot functionality, because part of the app configuration changes involve/depend slightly on existing and new snapshots. Ideally the full collection of snapshots should be part of the backup. Virtualization not an option, because the goal is to do performance evaluation on a very specific HW configuration. For the same reason, the spurious "back up" snapshots could skew performance data. Thank you

• Most scalable way of serving a small set of static HTTP content

  - by Ekevoo

  The story: Hi guys. I'm among the people responsible for serving the results of the most anticipated (by number of people participating) annual entrance exam in my state. As such, when our results are published, the interest is overwhelming. In the past we delegated the responsibility of serving the results to the media, but that spoils a little the officialness of these results. This year we went with a little (long overdue) experiment of using lighttpd instead of Apache as well as other physical network optimizations I wasn't directly involved with. The results were very satisfactory. The server didn't choke even once, nor we saw any of the usual Twitter complaints on unavailability and/or slowness that were previously common. However, because we still delegated the first publication of the results to the media I'm still not 100% sure we can handle the load of actually publishing the results first. The question: Now because these files are like 14MB in total and a true lightweight Linux distribution isn't that big either, I'm thinking: what if next year we run full RAMdrive? Is there any? Is that useful? Is that worth it for a team that uses Debian almost exclusively? Are there other optimizations that I should be focusing on instead?
