• Apache2 Startup warning: NameVirtualHost *:80 has no VirtualHosts

  - by Kit Roed

  When my Ubuntu Apache server (apache2) starts up I get a warning message that reads: [warn] NameVirtualHost *:80 has no VirtualHosts however, the web server is working fine... could anyone explain what I might have wrong in my site's configuration to make it give me this warning? the config file in question (located in /etc/apache2/sites-available) reads like this (details removed for brevity) <VirtualHost *> <Location /mysite> # config details here... </Location> # use the following for authorization <LocationMatch "/mysite/login"> AuthType Basic AuthName "My Site" AuthUserFile /etc/sitepasswords/passwd Require valid-user </LocationMatch> </VirtualHost> Could the fact that I'm using <Location> be a part of the problem?

• Duplicity Full Backup Lifetime and Efficiency

  - by Tim Lytle

  I'm trying to work up a backup strategy for some clients, and am leaning towards duplicity for remote backup (already use rdiff-backup for internal/on location backups). Is it reasonable to want a full backup every so often? Since duplicity increments forward, each incremental backup is relying on the previous increment, and all are relying heavily on the last full backup. Should that become corrupt, bad things happen. A related question: Does Duplicity test the incremental backups for consistency? Assuming I do want a full backup every so often, how efficiently does duplicity create that full backup? Can/does it check file signatures and copy unchanged data from previous full backups/increments? Basically creating a new 'full' archive transferring new/changed data and merging existing unchanged data? Right now my concern is that running a full backup is needed, but the consistent large bandwidth use of full backups will make this unreasonable for some clients.

• Can I use a 27" iMac as a additional monitor for another 27" iMac?

  - by Darren Newton

  I currently have a 27" iMac i7 with the 512mb ATI card. After looking at prices on other Apple displays it appears I can purchase another low-end 27" iMac (Core 2 Duo basic model) for less than a 30" display. 3 Part question: Can I easily use the lower-end iMac as an additional monitor to my higher end iMac? While I am using the lower-end iMac as an additional monitor can I still take advantage of its CPU to do things like run a webserver, compress video with Handbrake, etc? Are there any other 27" LCD displays with the same resolution (2560 x 1440) cheaper than the basic iMac (~$1699.00 US)? Any insights appreciated.

• Clearing Java certificates cache (force reload certificates)

  - by AlbertoFEM

  A simple question here. One application gave me this exception when trying to access a website with a expired certificate: java.security.cert.CertificateExpiredException So, I renewed the certificated from the website machine and restarted it. When I try to access it from Firefox or Chrome it will load the new certificate (which it's expiration date is set somewhere near 2040). The problem is, Java applications doesn't seems to renew this certificate, it seems to be stuck in some kind of internal cache. I already tried to add it to the keystore and set options in the application properties like -Dcom.sun.net.ssl.checkRevocation=false. No matter what I do, it always throw me a java.security.cert.CertificateExpiredException Any ideas?

• Email deliverability -- Whitelist solution or Email delivery service?

  - by JoefrshnJoeclean

  Hey Folks -- our company is encountering the same recurring problem - email deliverability. A lot of our emails are still getting trapped in yahoo and gmail spam filters. We followed yahoo's best practices guide as well as tips Ive found on serverfault. (setting up DKIM, SPF) And even took the Email Server Test (http://www.allaboutspam.com/email-server-test/) Now my question is: has anyone had success using whitelist solutions like goodmail or EmailReach? Alternatively, Im beginning to think that going with a email delivery service like Mailchimp will save me the headache and future stress of managing our email lists. So whitelist solution or just fork up the money and send via an email delivery service? Thanks!

• Excel crashes when opening Excel files from Internet Explorer

  - by Rob

  I have been running into some issues when opening Excel files from Internet Explorer, generally the first document or two will open fine but after that trying to open a file will cause Excel and Internet Explorer to crash to the desktop without any notifications being given. This doesn't happen for users who are running Excel 2007, but for users with Excel 2003 it may or may not happen to them. The files in question are Excel XML files and Internet Explorer 6 and Excel 2003 are being use. At this time it would not be possible to upgrade Internet Explorer, but it would be able to upgrade to Excel to version 2007 if that would resolve the issue. Overdue Update: We recently upgraded to Firefox at the office which has rendered this error a non-issue; however, it is still unresolved from the standpoint that we haven't been able to come up with an explanation to the issue. Since IE6 is still installed on the systems, a fix to the problem (or explanation of why it's happening) would be appreciated.

• Unlimited and multi-computer online storage solutions with automatic backup

  - by JRL

  As the title says, what are the existing online storage solutions that provide: unlimited storage automatic backup and allow for an unlimited number of computers (use not tied to a single computer)? There are several existing questions on this site related to online storage solutions, but none that is specifically targeted to what I want, so I thought I'd ask the question. This wikipedia article lists some of them, are there others? How do they compare in terms of price, feature set and ease of use? Update: Kinda disappointed no one has any answers to this so far. JungleDisk looks promising, anyone have experience with it? Update 2: To answer the comments, what I'm looking for definitely DOES exist. These solutions all seem to fit the bill: BackMii CrashPlan DataPreserve Humyo JungleDisk KeepVault SpiderOak And some of them are quite cheap (CrashPlan is $100 a year). For unlimited space and computers, I'd say that's pretty good. Does anyone have experience with CrashPlan or any other of the above solutions?

• User Provisioning Tool for SQL Server 2008?

  - by Rob Sanders

  Yesterday I moved my machine from one domain to another - foolishly forgetting the implications for my local instance of SQL Server! Mixed Mode authentication is not enabled, and the only local account login has only "public" permissions. SQL Server 2005 Service Pack 2 had a tool called the User Provisioning Tool for Windows Vista (sqlprov.exe) which allowed you to add Domain Users to a local SQL 2005 instance (it doesn't work against SQL 2008 btw) - my question is.. is there a similar tool for SQL Server 2008 or am I going to have to do a reinstall? Also let me know if you think this belongs on StackOverflow

• Upgrade from Debian Lenny to Squeeze with apt-get

  - by Fabio

  I just upgraded my system from Lenny to Squeeze following the steps posted here. I followed all the steps using apt-get (in the upgrade from Etch to Lenny i used aptitude as suggested) and the upgrade went fine. In the daily routine I use aptitude to maintain the system up to date and I really like the automatic handling of unused packages, so if I install package A that depends on B when I remove A, B is removed too keeping my system clean. My question is the following: do apt-get and aptitude share the automatic handling of packages? I don't think so, because I found a lot of packages not marked as Auto in aptitude after the upgrade via apt-get. Am I right? How can I fix this in automated way if the answer is yes?

• MemCached on Windows x64

  - by Django Reinhardt

  This question has previously been asked, but that was a year ago and I wanted to know if there had been any developments since then. Basically we'd like to use a MemCached Server on a Windows Server 2008 R2 machine... which is only x64, obviously. I haven't found any details on a Win64 version of MemCached, but there is still the solution from the previous thread (which I haven't tried yet) to use a bit of software called MemCacheD Manager running MemCached 1.2.6. However, the current version of MCd is 1.4.4 and I was wondering if there had been any improvements since then.

• Hyper-V Deployment Options Best Practices

  - by Erv Walter

  In what circumstances would you choose each of the following deployment options: Hyper-V installed as the bare bones Windows Hyper-V Server 2008 R2 Hyper-V role installed on a Windows Server 2008 R2 Server Core installation Hyper-V role installed on a Windows Server 2008 R2 Full Installation For example, I know there are licensing considerations for each option: With Hyper-V on top of a full installation of Enterprise or Data Center edition, you can use Windows Server as a guest OS without needing additional licenses (4 for Enterprise, unlimited for Data Center) With "Windows Hyper-V Server" you have to obtain licenses for each guest OS. But my real question is, are there technical considerations as well? I understand that the Full Installation doesn't perform as well as the other two options, but is there a significant difference between Server Core and "Windows Hyper-V Server"? What are the pros and cons of Hyper-V on Server Core vs "Windows Hyper-V Server" and when would you choose each?

• URL Rewrite is adding HTTPS to my canonical redirects in IIS7

  - by Derek Hunziker

  Hello, I have the following rule defined in my Web.config: <rule name="Enforce canonical hostname" stopProcessing="true"> <match url="(.*)" /> <conditions> <add input="{HTTP_HOST}" negate="true" pattern="^www\.mydomain\.org$" /> </conditions> <action type="Redirect" url="http://www.mydomain.com/" redirectType="Permanent" /> </rule> What I am experiencing is strange... It appears that I am being redirected to https://www.mydomain.com/ which causes my browser to hang. I do not have SSL encryption turned on, nor do I have any special authorization rules. The web server in question is behind an F5 load balancer. Any ideas?

• Cisco ASA bonding/teaming/port-channel capabilities

  - by Antoine Benkemoun

  Hello, This seemed to me like a really simple question that I would be able to answer by myself but I have not been able to find any info on this subject. I have a Cisco ASA 5510 which has 4 FastEthernet interfaces. I was wondering if it would be possible to use 2 or 3 of these interfaces as a port-channel in order to agregate bandwidth for multiple VLANs. I have found no info on the Cisco website nor on Google. Is this just a stupid/crazy idea or am I missing something ? Thank you in advance for your help, Antoine

• Move smaller hard drive to partition on a larger hard drive

  - by bluejeansummer

  My parents bought a new hard drive for a laptop that I've owned for several years. It's much larger than the current one, so I plan on splitting it up to dual boot it with Ubuntu. I have no problem with partitioning a drive (I always keep a LiveCD handy), but my question is this: how can I go about moving the existing partition to the new drive? This is a laptop, so I can't simply plug the new drive into another slot. Also, even if I manage to move it, will Windows still work on the new drive in a larger partition? I've had this laptop for quite a while, and I've lost the recovery discs that came with it a long time ago. I also have a lot of software without CDs to reinstall them with. This makes not reinstalling Windows a high priority. In case it helps, both drives use 2.5" PATA, and I have a 1 TB external drive available if it's needed.

• Querying Active Directory in PowerShell from a Windows host that is not a member of the domain

  - by jshin47

  How can I use PowerShell [adsisearcher] to query a domain that I am not a member of? Usually I will do something like this: $myAdsi = [adsisearcher]"" $myAdsi.SearchRoot = [adsi]"LDAP://dc=corp,dc=mycompany,dc=com" $myAdsi.Filter = "objectCategory=computer" $res = $myAdsi.FindAll() If I run this snippet on a host in my domain, I get the expected result. However, if I run this from a computer that has network access to the domain (through a L2L VPN) I get the error: Exception calling "FindAll" with "0" argument(s): "The specified domain either does not exist or could not be contacted. " At line:11 char:33 + $adComputers = $searcher.FindAll <<<< () + CategoryInfo : NotSpecified: (:) [], MethodInvocationException + FullyQualifiedErrorId : DotNetMethodException This is somewhat expected as I have not provided any sort of credentials to [adsisearcher] that would tell it how to authenticate. My question is: how do I let [adsisearcher] know that I want to authenticate against a domain in which I am not a member?

• EC2 hosted service multi-tenant dynamic DNS solution

  - by accidental admin

  I want to change the model of my EC2 hosted service to have a separate sub domain for each tenant (ie. .example.com). My primary DNS is now with dnsmadeeasy.com, but their dynamic DNS offering seem pretty weak: it requires the API to use my full dnsmadeeasy.com account credentials, I rather have the API use a limited privilege credential that can only add/remove/modify subdomain records from what I gather it only allows to modify existing records, does not allow me to dynamically add/remove records for new tenant subdomains My question what are my alternatives? Is there something in the dnsmadeeasy API offering I misunderstood and I should just use them? Is there some other similar DNS service that has a DDNS offering that satisfies my requirements? Or should I just bite the bullet and host my own DNS (my fear is not configuration/learning/know how, my fear is reliability). If you recommend the latter, can you detail the necessary steps or a link to a good tutorial how to?

• How do I find out what the Finder is busy with?

  - by Peter S Magnusson

  I'm running Snow Leopard on a MacBook Pro. My Finder has decided to be very busy, and neither restarting Finder nor a reboot cools it down. Spotlight doesn't report activity, Time Machine isn't busy, yet top -ocpu reports Finder is running between 30% and 100%. Update: none of the suggestions have worked. At this point (three months after first asking the question), I'm resigned to wait until the new MacBook Pro comes out and start with a clean install. Very frustrating that there's no way to investigate what the Finder gets stuck on.

• Windows7 and Virtual PC guest copy/paste intermittent delay

  - by James

  I've been using Virtual PC for some time now and have not had any issues with copy and paste until I upgraded my host to Windows7 64-bit. After the upgrade sometimes when I copy and paste some text there is like a 15-20 second delay before it completes, this is very frustrating when I'm trying to get my work done. The problem seems to be intermittent in nature, it seems to occur when I have not done a copy paste for a while. After the delay occurs copy and paste seem to work at normal speed until I don't copy and paste for a good length of time. My question is, is there any solutions or patches that can fix this copy/paste issue for virtual PC running in a 64-bit windows7 host?

• Forward local port or socket file to remote socket file

  - by Ninefingers

  Hi All, Quick question - I run two linux boxes, one my own desktop and the other my VPS. For security reasons on the VPS end I opted for socket connections to MySQL (/var/run/mysqld/mysql.sock). I know I can tunnel like this: ssh -L 3307:127.0.0.1:3306 [email protected] if I set up the remote sql server to listen on some port, but what I want to know is can I do something like: ssh -L /path/to/myremotesqlserver.sock:/var/run/mysqld/mysql.sock thereby tunnelling two sockets, as opposed to two ports? A perfectly acceptable solution would also be to forward a local port to the remote socket file, but where possible I'm trying not to have tcp servers running on the remote box. (and yes, I know tcp would be easier). Thanks all, Nf.

• Creating a new Active Directory account with an InfoPath form

  - by ryan

  I am setting up a business partner portal in our Sharepoint server. There will be an AD group with permissions limited to viewing and possibly contributing to the specific business partner site and employees of our business partners will have accounts created for them as needed. Now we would like to let our business development group(BDG) have control over the partner accounts. Ideally they should be able to add and delete accounts and change permissions on them. The BDG are not domain admins so we don't want to give them access to the domain controller. We want to create an Infopath form that will allow them to do all this. Is it possible to create and manage AD accounts from within an Infopath form on the sharepoint server? I searched this site and MSDN and can not find anything specifically related to my question.

• Make bootable iso with grub chainloading

  - by hlovdal

  My parents' pc has windows 7's boot manager installed at MBR and grub2 is installed on /dev/sda2 (booting linux on /dev/sda2). I want to make a bootable cd so that when booted from it just chainloads into the boot manager on the second partition. I assume using grub rather than grub2 for this will be simpler, using the configuration timeout=0 hiddenmenu default=0 title grub2 (/dev/sda2) rootnoverify (hd0,1) chainloader (hd0,1)+1 I know I can make a bootable linux cd in various ways, but that is not what I want. I just want to put grub/grub2 on the cd, no kernels or programs. The question is how do I make the iso file? I have found some references to installing on a floppy or usb disk, but all those assume the device is present when running the grub install commands. A iso file is different.

• Cisco ASA 5510 ASDM: Setting up multiple public static ip addresses on a single interface and route

  - by ssjaken

  HI, i have a cisco ASA 5510 using ASDM version 6.3 We have a webserver that is been written very specifically and i was given super direct "DO NOT DEVIATE" directions. This server has to get traffic from 3 different PUBLIC ip's that we own. (our isp gave use a block of 12 static addresses) on 4 different ports. there are the directions i was given externalIP1:22 - 172.17.5.50:22 - SSH externalIP1:443 - 172.17.5.50:23040 - SIT externalIP2:443 - 172.17.5.50:33040 - STAGE externalIP3:443 - 172.17.5.50:43040 - PROD My first question is, using ASDM (my contract employer demands i use ASDM over CLI) how do i get three public addresses to work on one interface. We are authenticating on PPPoE. I know create a virtual interface with the static address but when i do i cannot ping the address from another offsite machine. secondly, where would i put the traffic redirect in. would i go ahead and create ACL's or just make NAT routes. Thanks.

• How can I install the latest full version of Canon ZoomBrowser EX without the original CD?

  - by Sorin Sbarnea

  ZoomBrowser EX comes with Canon cameras. Canon software enigeering team did a really poor job analyzing how people are using the software: people do lose their x-year old CD or do not have it with them when travelling do not have a CD drive at all (very common nowdays) Canon updater from their website does not allow you to install the software if it does not find the original CD in the drive. The question is how do I trick the installer to run on a computer and install the product that I payed for. Currently the latest version is 6.5.1.15 and you can download the updater from Canon website. In fact the updater is just the full installer but it doesn't allow you to install if it doesn't find a previous install or the original CD. Note: In the past I used to save a registry file with registry keys used by it, loading it did allowed me to run the installer but now, with Windows 7 x64 it seams that it doesn't work anymore.
