  • Ignoring GET parameters in Varnish VCL

    - by JamesHarrison
    Okay: I've got a site set up which has some APIs we expose to developers, which are in the format /api/item.xml?type_ids=34,35,37&region_ids=1000002,1000003&key=SOMERANDOMALPHANUM In this URI, type_ids is always set, region_ids and key are optional. The important thing to note is that the key variable does not affect the content of the response. It is used for internal tracking of requests so we can identify people who make slow or otherwise unwanted requests. In Varnish, we have a VCL like this: if (req.http.host ~ "the-site-in-question.com") { if (req.url ~ "^/api/.+\.xml") { unset req.http.cookie; } } We just strip cookies out and let the backend do the rest as far as times are concerned (this is a hackaround since Rails/authlogic sends session cookies with API responses). At present though, any distinct developers are basically hitting different caches since &key=SOMEALPHANUM is considered as part of the Varnish hash for storage. This is obviously not a great solution and I'm trying to work out how to tell Varnish to ignore that part of the URI.

  • On booting my laptop warns me about failure of hard disk is imminent...can it be repaired or to be replaced..?

    - by nrb
    when I am booting my laptop (Lenovo G550) it gives an error message prior to that.. SMART Failure Predicted on Hard Disk O:Hitachi HTS543225l9A300-(PM) Warning : Immediately back up your data and replace your hard disk drive. Afailure may be imminent. Press F1 to continue.. Once it started, it runs smoothly, I also verified its status by running some internal HDD tests by Hard Disk Senitel software..It shows no bad sector , no virus, no damage , normal temperature ... it suggests every thing is OK except its health... Now my question is that then what is the wrong with it..? It may be wrong with plates (dusty) or the read/write heads...then can I go for repair it or replace it...? My system now reminds me every half an hour to resolve this problem since last 10 days... Help me.

  • Apache mod_rewrite redirect with prefix

    - by Marc
    I am newbie with Apache's mod_rewrite and I'm having some difficulties getting it to do what I want. In my static directory, I have some javascript files (.js) with 2 kind of filename: xxxx.js which is the standard file name AT_xxxx.js (with prefixed filename) which has been duplicated from previous standard file name but also contains my customizations I would like to parse requests for each standard requested javascript file (xxxx.js) to check if a customized file exists (AT_xxxx.js) including all sub-directories. Then, in this case, use the custom file instead of the standard file (perhaps by internal redirect). I tried to figure this out for hours but something is still wrong. Note: Also, I don't know how to find custom files in sub-directories. DocumentRoot "/data/apps/dev0/custom/my_static" <filesMatch "\\.(js)$"> Options +FollowSymLinks RewriteEngine on RewriteCond %{DOCUMENT_ROOT}/AT_$1.js -f RewriteRule ^(.*[^/])/?$ %{DOCUMENT_ROOT}/AT_$1.js [QSA,L] </filesMatch>

  • Software RAID 10 on Linux

    - by vpetersson
    For a long time, I've been thinking about switching to RAID 10 on a few servers. Now that Ubuntu 10.04 LTS is live, it's time for an upgrade. The servers I'm using are HP Proliant ML115 (very good value). It has four internal 3.5" slots. I'm currently using one drive for the system and a RAID5 array (software) for the remaining three disks. The problem is that this creates a single-point-of-failure on the boot drive. Hence I'd like to switch to a RAID10 array, as it would give me both better I/O performance and more reliability. The problem is only that good controller cards that supports RAID10 (such as 3Ware) cost almost as much as the server itself. Moreover software-RAID10 does not seem to work very well with Grub. What is your advice? Should I just keep running RAID5? Have anyone been able to successfully install a software RAID10 without boot issues?

  • Secure external connection to SQL Server (from third party software)

    - by Bart
    I have a SQL Express 2008 R2 server running on a server in an internal lan network. A few databases are used by some third party software to store data. A SQL-Server user is used by this application to connect to the database. Now I need to access this database using a local installation of the software from an external pc. In this particular case a VPN connection is not the solution I am looking for. I have access to an external linux server, so I tried ssh tunneling from the windows server to the linux server and use the external pc to tunnel it back from the linux server to the client, but this is working very very slow. What are my other options to allow this external connection in a safe way?

  • Nearest PC equivalent to Mac Target Disk Mode?

    - by username
    Mac firmware has a special boot mode that allows you to offer its internal hdd to another computer as an external disk (you just connect the two machines via an IEEE 1394 cable). Only the second machine needs a functioning OS installed. Any good suggestions for something similar on the PC side of things? Block level access isn't important to me, I'd just like to be able to copy files off it. It doesn't matter to me if it uses Ethernet, IEEE 1394, or wifi - I just like having a quick way to access files on a client PC. Is there any single-purpose Linux distro specially designed to do this? It'd be nice to have something super simple, quickbooting, and small that I could install on a USB drive. I used to use Knoppix, but it's overkill as a Target Mode replacement.

  • Cisco ASA - Enable communication between same security level

    - by Conor
    I have recently inherited a network with a Cisco ASA (running version 8.2). I am trying to configure it to allow communication between two interfaces configured with the same security level (DMZ-DMZ) "same-security-traffic permit inter-interface" has been set, but hosts are unable to communicate between the interfaces. I am assuming that some NAT settings are causing my issue.

  • How should I remotely manage Dell Poweredge 2850 running Ubuntu server?

    - by Saul
    First I've got to say I'm a Linux / Ubuntu novice, so go gentle on me as I'm on day 3. I've managed to get Ubuntu server Ubuntu 8.04 LTS installed and running on the Poweredge 1850 I bought off ebay. The box will go in a rack at my office but I want to be able to work on it and power on and off from home and I gather that (maybe) IPMI over LAN might be the way to do this, or maybe its something to do with BMC or something? I want to be able to administer/manage from a client PC at home running XP. I will be configuring the office router to port forward port 80 and 443 to the Ubuntu server running Apache2, and I'm puzzled about how the remote management works (unless it comes on a different port forwarded to a different internal IP) Thanks for any help

  • Per-machine decentralised DNS caching - nscd/lwresd/etc

    - by Dan Carley
    Preface: We have caching resolvers at each of our geographic network locations. These are clustered for resiliency and their locality reduces the latency of internal requests generated by our servers. This works well. Except that a vast quantity of the requests seen over the wire are lookups for the same records, generated by applications which don't perform any DNS caching of their own. Questions: Is there a significant benefit to running lightweight caching daemons on the individual servers in order to reduce repeated requests from hitting the network? Does anyone have experience of using [u]nscd, lwresd or dnscache to do such a thing? Are there any other packages worth looking at? Any caveats to beware of? Besides the obvious, caching and negative caching stale results.

  • Upgraded from VS 2008 -> VS 2010. Can't Connect to SQL Server in Staging Environment

    - by Bob Kaufman
    I have a test application written in C#/ASP.NET that I've developed using Visual Studio 2008 Professional/.NET 3.5 which connects to a local SQL Server 2008 Express instance. I upgraded the development machine to Visual Studio 2010 Professional maintaining .NET 3.5 and everything in the development environment continues to work correctly. Upon deployment of the new app to an internal staging machine, that app cannot connect to its local SQL Server 2008 Express database. I get the customary "server not found" error: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible... Does something need to be upgraded on the staging machine to be able to host a Visual Studio 2010/.NET 3.5 application?

  • Can I use a display driver from Windows 8 in Windows 7?

    - by adam0101
    My latest display driver doesn't support WDDM 1.0, and I need it to be at least version 1.1. I've been attempting to get the Windows Phone 7 SDK working on my HP Pavillion dv9000, but the phone emulator requires 1.1 or higher. My drivers are as up-to-date as they can get. I even tried a modded driver found here, but no go. Then, while evaluating Windows 8 Developer Preview on a different partition I noticed that dxdiag.exe showed it was using WDDM 1.2. I tried installing Windows Phone 7 SDK on Windows 8, but I get an "Internal Error" popup and "Connection failed because of invalid command-line arguments" in the error window in Visual Studio. I'm guessing because Windows Phone 7 SDK isn't supported on Windows 8 yet. So my question is this: Can I get Windows 7 to use the display driver Windows 8 is using to get WDDM 1.2 on Windows 7 and how would I go about doing it?

  • 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 ;-)

  • Vmware sphere setting up external network

    - by Tom Beech
    I've just setup vmware vsphere 5 on a remote server (rented dedicated server). I've added my first VPS (centos 5.8) barebones. It's not finding any IP (internal or external) on boot. I've had an extra external IP assigned to my server that I wanted to use on the VPS. I tried editing the eth0 config and adding the IP in there and turning off the DHCP, but it can't find any IP or ping google or do any networking type things. How do I route the IP to my VPS so I can access it remotely?

  • Disable/enable the proxy on a tab by tab basis in Firefox

    - by Rich
    Is it possible to disable/enable the proxy connection on a tab-by-tab basis in Firefox? I can access the internet with the proxy enabled, and I can access our internal servers with the proxy disabled, but neither configuration allows the other. I have a feeling that Firefox 4's per tab profiles may permit this, but was wondering whether there was a way to achieve this on Firefox 3.6.13, perhaps through the use of an extension. For the moment I'm making do with quickProxy (not QuickProxy which I've just discovered while trying to find quickProxy) which allows me to switch the proxy on and off for the whole browser, but would prefer something more fine-grained.

  • Google Chrome app file opened is not always in front, receiving focus

    - by Philipp Lenssen
    On Windows Vista, I'm launching files associated with a Google Chrome "Application Shortcut" app by double-clicking them. While they will always open this way, they will sometimes not receive focus -- i.e. they sit in the task bar quietly but don't actually show in front on the screen (until I click on the app in the task bar again). Does anyone know how I can force the just-opened app to receive focus? The app being opened actually contains a web app I can customize, so I also have access to performing JavaScript commands post-startup. For background information, here is the regedit file I originally used to create the file association. Might well be this is a Google Chrome internal issue... apps I open with other editors get their focus alright, AFAIK. Thanks!

  • Cloning Win 7 installation from MBR to GPR drive and make it bootable

    - by Nelluk
    I've seen threads on similar topics - such as this one - but the answers never seem to solve how to make it bootable. I have Win 7 64-bit on a PC installed on a 2tb MBR volume. The motherboard is UEFI compatible. I just installed a secondary internal 3TB drive which will be partitioned as GPT. Is there a relatively easy way to clone my installation over to the new drive and have that drive be bootable? I have used EaseUS Partition Master to clone the C volume to the D volume, but that would not boot and I assume the issue is that one is MBR and one is GPT. Is there a process to do this?

  • My EEEPc 900HA won't turn on/boot. Can it be fixed or does it need to be sent in?

    - by th3dude19
    My EEEPc 900HA stopped booting up out of nowhere. It went to sleep and when I went to wake it up, it wouldn't wake up. I powered down and went to power back up, but no go. The power light comes on solid and the battery/corded power light blinks consistently. There is no HDD activity or light activity. No BIOS. Just the lights described. I've troubleshooted the RAM, HDD, and internal power connections and everything checked out both on battery power and corded power. I've also reset the CMOS to no avail. What else can I do?

  • Wildcard SSL Certificates with Exchange 2010?

    - by Hutch
    Is anyone using a Wildcard Cert with Exchange 2010 please? We currently have a bunch of individual whatever.domain.com SSL certificates and as several are expiring soon it would be an ideal opportunity to move to a wildcard certificate. At some point though we will be moving from Exchange 2003 to Exchange 2010, and I've read conflicting reports over whether wildcard certs work with Exchange 2010 as many guides seem to recommend a UCC/SAN certificate. Our internal DNS domain name is the same as our external domain name. Godaddy look like good VFM given they allow use on unlimited physical servers. Thanks in advance.

  • Group Policy Task Schedule deployed to User Configuration not working, works when in Computer Configuration?

    - by user80130
    I added a Scheduled Task on my Windows 2008 R2 Domain Controller in the Group Policy Manager: MyDomain Policy User Configuration Preferences Control Panel Settings Scheduled Tasks Basic Task, like starting notepad, when user unlocks his workstation. This should show up in the client workstation's task scheduler, but it dosn't. No errors or anything like that. If I use the "Computer Configuration" instead of "User Configuration" the task appears, and I'm able to run the task. I've tried the gpupdate /force followed by gpresult and checked the report, but it dosn't contain the GPO Scheduled Tasks I created? (again, does show up when using "Computer Configuration".) The issue is that I have to run the application in the current users context, and only on a specific Employee OU, and thereby limit this task only to Employee Workstations and not apply the application when the same employee log on to internal servers and such. Primary domain dontroller is a Windows 2008 R2, workstations Windows 7 Enterprise. What am I doing wrong ?

  • OpenVPN server behind firewall issues

    - by Gabriel
    I'm trying to setup an OpenVPN but I do have some problems doing it. This is my scenario: INTERNET --- HOME ROUTER (10.1.0.0/28) --- FIREWALL SERVER (DEFAULT GATEWAY FOR MY INTERNAL LAN 10.1.0.2) --- OpenVPN Server (10.1.0.9 LAN | 10.2.0.1 VPN) single nic / bridge iface I can connect to my VPN server successfully (it gets the 10.2.0.5 address). Though, I'm not able to ping anything, neither my VPN server, nor my lan clients. I guess the problem is on the firewall. I'm not really an expert on iptables, I tried adding plenty of different rules without success. I would appreciate a lot if someone could explain me how to get to work the VPN server in this scenario. After connecting through VPN, when I try to ping the server, I'm not really sure about how the ping message gets to the server and how the response should go back to the client. Thanks a lot Gabriel

  • Linux how to force an external ping from eth0 to eth1 without a router.

    - by Elie
    Hello, i am trying to have eth0 connected to eth1 on the same machine with a loopback cable. I have eth0 as 2.2.2.1 and eth1 as 2.2.2.2 with netmask 255.255.255.0 and the right Bcast 2.2.2.255 . I tried to ping -I eth0 2.2.2.2 and ping -I eth1 2.2.2.1. My issue is that even when the loopback cable is not plugged the ping still succeed( as if it is an internal ping). How can I force an external ping where I make sure the packets are going through the connected cable? ( I know I can have a router and both ethernets connected to it, but I am avoiding to use anything besides a simple cat 5 cable). Thanks.

  • How do I handle mysql replication in EC2 using private IPs?

    - by chris
    I am trying to set up a mysql master/slave configuration in two EC2 instances. However, every time I reboot an instance, the IP address (and hostname) changes. I could assign an Elastic IP address, but would prefer to use the internal IP address. I can't be the first person to do this, but I can't seem to find a solution. There are a lot of "getting started" guides, but none of them mention how to handle changing IP addresses. So what are the best practices to manage master/slave replication in EC2?

  • Firefox: This connection is untrusted + Behind corporate firewall

    I've seen some similar issues strewn throughout Google's results about this, but none seem to be corporate-specific. I continually get the 'This connection is untrusted' screen every time I attempt to log into a secure site...for instance Gmail. This is pretty annoying as sometimes I have to go through the process of adding the exception two or three times before it finally lets me into Gmail. I am behind a corporate firewall, going through an internal proxy server to get to the Internet, so there is no possibility for me to update the firewall...etc. Does anybody know a way around this? Can it simply be disabled (and is that safe)? EDIT I'm going to reopen this question with a bit of new information. I have been using Google Chrome lately until today, and one thing that I noticed was that I never had this issue when using either Chrome or Internet Explorer. Is there something that these other browsers do that I need to manually do in FF?
