  • DNS with Amazon EC2 Elastic Load Balancer

    - by user68173
    I'm told that I can't make the root of a domain (example.com) a CNAME - I have to specify an IP. Given that you can't use an IP address to point at your Elastic Load Balancer, what's the best thing to do? Currently I do this: example.com - A record to elastic IP of first server- redirects to www.example.com www.example.com CNAME to hostname of load balancer If the first server is out of action, the redirect will fail. Is there a better way to approach this?

  • Uninstaller that can work with failed installs

    - by Nifle
    I'd like an application that can uninstall applications that does not show up in the normal add/remove applications. I have an application that failed to install properly. It installs half way and then crashes leaving short cuts, folders with exe and config files in and some stuff in the registry. Ideally I would like to be able to point the uninstaller to the install dir and tell it to remove everything that references files in that dir.

  • No mysql password under linux?

    - by ripper234
    I was told that mysql user, similar to root user, by default "has no password". Not an empty password, but rather "no password". I wasn't aware this situation was possible - I thought every user on a linux had to have a password. Am I wrong? Can you point me to a link that explain this?

  • Attempting to ping RPC endpoint 6001/6004 (Exchange Information Store) on server on Exchange2010

    - by MadBoy
    I have Exchange 2010 in hosting setup like: TMG 2010 as load balancer Exchange 2010 x 2 (CAS,MAILBOX,HUB on each server) AD1, AD2 machines File witness All people currently connect thru OWA or POP3/SMTP and that works fine. The problem is autodiscovery doesn't work and RPC in terms of setting up Outlook doesn't work too. It doesn't work if I am connected with VPN or not. The thing is it used to work. Before reinstall of my machine 2 days ago I was able to get mails successfully thru Outlook that was set up using autodiscovery (but I was getting reports setting up of new clients wasn't working - so not sure why my outlook continued to work). I used https://www.testexchangeconnectivity.com to track it down and basically the message is more or less this: Attempting to ping RPC endpoint 6004 (NSPI Proxy Interface) on server autodiscover.domain.pl. The attempt to ping the endpoint failed. Additional Details The RPC_S_SERVER_UNAVAILABLE error (0x6ba) was thrown by the RPC Runtime process. I tried different solutions like disabling IP v6, followed couple of links and did all they proposed and it's still at the very same point: C:\Users\admin>netstat -a | find "6001" TCP 0.0.0.0:6001 EXCHANGE2:0 LISTENING TCP [::]:6001 EXCHANGE2:0 LISTENING C:\Users\admin>netstat -a | find "6002" C:\Users\admin>netstat -a | find "6003" C:\Users\admin>netstat -a | find "6004" I followed (and few others): http://helewix.com/blog/index.php/Microsoft-Solutions/2011/02/10/exchange-2010-how-to-open-ports-6001-6002-and-6004-on-your-server-for-telnet-to-work-and-rpc-to-be-able-to-connect-2 http://blogs.technet.com/b/exchange/archive/2008/06/20/3405633.aspx http://messagexchange.blogspot.com/2008/12/outlook-anywhere-failing-rpc-end-points.html Although most relate to Exchange 2007 and I have Exchange 2010 but there's not much things I can find on Exchange 2010 for the current problem. After applying all of those solutions error 6004 changed into error 6001 which doesn't bring me to my problems any closer. At this point even thou error was 6001 and 6004 was no more the 6004 port was still closed while 6001 stayed open. Attempting to ping RPC endpoint 6001 (Exchange Information Store) on server autodiscover.domain.pl. The attempt to ping the endpoint failed. Additional Details The RPC_S_SERVER_UNAVAILABLE error (0x6ba) was thrown by the RPC Runtime process. C:\Users\admin>netstat -a | find "6001" TCP 0.0.0.0:6001 EXCHANGE2:0 LISTENING TCP [::]:6001 EXCHANGE2:0 LISTENING C:\Users\admin>netstat -a | find "6002" C:\Users\admin>netstat -a | find "6003" C:\Users\admin>netstat -a | find "6004" So I reverted back to square one. I suspect it's a problem with TMG but really can't be sure. I tried multiple combinations but all fail.

  • cgconfig.conf : setting root control group parameters

    - by delerious010
    I've got cpu, cpuacct and memory cgroups configured via /etc/cgconfig.conf ( cgconfig-bin on Lucid ). I can add new control groups, and assign processes to them however there does not seem to be a facility for changing the paramters of the root level memory cgroup ( the actual mount point ). How would one best set such parameters in a clean manner withoput c For example, I've the memory cgroup mounted to /var/run/cgroup/memory. I'd like to have /var/run/cgroup/memory/memory.use_hierarchy set to 1 on boot.

  • Editting HD Quicktime .mov files in Windows

    - by NoCarrier
    I recently purchased one of those new wave of point & shoot digicams (canon SD780) that shoot high definition 720p video. Unfortunately it only writes to Quicktime files. How can I go about editing these in Windows without spending any money? I found a few MOV to AVI or WMV converters but am experiencing some quality degradation in the output.

  • Server 2012, ADFS 2.1, and Office 365

    - by Matt Bear
    Has anyone gotten ADFS 2.1 on Server 2012 working with o365 SSO? I have it working up to a point, I tweaked the registry to allow the powershell commands to run, user accounts syncs fine. Even the remote connectivity analyzer shows no errors. But SSO itself does not seem to be passing the credentials correctly. Microsoft claims that ADFS 2.1 is not supported to work with o365, but I'm just being stubborn and not giving up that easy.

  • Cannot uninstall XP SP3 update

    - by wfaulk
    I need to uninstall Service Pack 3 because it broke a program I rely on (FrameMaker). I have done this before on other computers using Microsoft's SP3 uninstall instructions. However, on this computer, SP3 is not listed in Add/Remove Programs (and, yes, I have checked the "Show Updates" checkbox), there's no "$NtServicePackUninstall$" restore directory, and either Windows didn't create a restore point for the SP3 install or it has fallen off of the list of restorable points. Does anyone know of any other options?

  • gotomypc and aircard?

    - by user13743
    My boss is looking at getting an aircard ( internet over cell network ) for his laptop. One of the uses he mentioned was gotomypc. I couldn't find good information on it, but I was thinking it would blow out the bandwidth because it was like streaming a movie. Is gotomypc really feasible with an aircard at this point?

  • What is a vim "runtime directory"?

    - by Andres Jaan Tack
    I'm trying to get started with things like FuzzyFinder, but I am stuck at the point where it says: INSTALLATION fuf-installation Put all files into your runtime directory. If you have the zip file, extract it to your runtime directory. You should place the files as follows: your_runtime_directory/plugin/fuf.vim ... What is my "runtime directory"? How do I know if I have one? Why does it matter how I put things into it?

  • Backing Up vs. Redundancy

    - by TK Kocheran
    I'm currently in stage 2 of 3 of building my home workstation. What this means is that my RAID-0 array of solid state disks will be backed up nightly to a RAID-5 or RAID-6 array of traditional spinning hard disks. However, it recently dawned on me that redundancy is not backup. The main reason for setting up a RAID array with redundancy was to protect myself in the event of a drive failure to serve as an effective backup solution. Wait. What if a bolt of lightning finds a way to travel into my house, through my surge-protector, into my power supply and physically destroys all of my hard disks and SSDs? Well, in that case, I guess I'd be fine because I generally keep most important files (music, pictures, videos) stored in multiple places like on my laptop, my wife's laptop, and an encrypted USB hard drive. Wait. What if a giant hedgehog meteor attacks my house from space traveling at mach 3 and all machines and hard disks are blown to smithereens. Well, I guess I could find a way to do ridiculously slow and cumbersome rsyncs or backups to Amazon's Glacier. Wait. What if there's a nuclear apocalypse... and at this point I start laughing hysterically. At what point does backing up become irrelevant? I completely understand situation one (mechanical drive failure), situation two (workstation compromised or destroyed somehow), possibly even situation three (all machines and disks destroyed), but situation four? There's no questioning the need for backups. None. However, there are three questions I'd really like addressed: To what level should one backup? I definitely understand the merits of physical disk redundancy. I also believe in keeping important files on multiple machines and thinning out the possibility of losing all of my files. Online backups make sense, but they beg the following question. What should I be backing up remotely and how often? It's no problem storage-wise to back up important files (music, pictures, videos) and even configuration and temporal data for all of the machines in my network (all Linux based)... albeit locally. Transferring to the cloud is another story. Worst-case scenario, if I lost all of my configuration for my individual computers, the reality is that I probably lost the machines too. The cloud is a long way away from here; I can run backups over CAT-6 here and see 100MB/s easily, but I'm afraid that I'm only going to see 2MB/s at best when transferring up to the cloud.

  • OpenOffice Daemon Problem

At this point, the open office applicattion don't work and the documents don't be generated. How can I restart automatically the openoffice daemon when this problem happens? Is there any way to monitor the service or to program a watchdog to handle it? Thanks in advance, regards.

  • File open fails initially when trying to open a file located on a win2k8 share but eventually can su

    - by Ruddy Douglass
    Core of the problem: I receive "(0x80070002) The system cannot find the file specified" for roughly 8 to 9 seconds before it can open it successfully. In a nutshell, we have two COM components. Component A calls into Component B and asks for a UNC filename to write to - the filename returned doesn't exist yet, but the path does - it then does its work, creates and populates the file, and tells Component B its done by making another com call. At that point Component B will call MoveFile to rename the file to its "official" name. This code has worked for (literally) years. Its works fine on win2k3. Its works fine when its running on win2k8 and points to a share on a win2k3 server. It also runs fine, if the share is actually located on the same win2k8 machine that the code is running on. But if you run it on win2k8 and point it to a share on a different win2k8 server, it fails. Both Component A & component B exist in their own Windows Service running with as a domain admin account. The shares are configured for "Everyone/Full control" in all test environments, similarly so are the underlying folders that the share points to. All machines are in the same domain. During debugging I realized the file actually does exist by the time I get to checking manually for it - after several iterations it occurred to me that the file doesn't "show up" until some delay passes by - so I put in the loop below in component B as shown below: int nCounter = 0; while (true) { CFileStatus fs; if (CFile::GetStatus(tempname, fs)) break; SleepEx(100, FALSE); nCounter++; } This code does, in fact, exit and nCounter is generally between 80 & 90 iterations when it does -- indicating the file "appears" approx 8 to 9 seconds later. Once that loop exits the code can successfully rename the file and all further processing appears to work. I put a CFile::GetStatus in component A immediately before it calls into Component B and that indicates success - it can see the file and get its true size yet the call into component b made immediately after can not see the file until the above indicated delay passes. I have verified the pathnames are precisely the same, even though it would clearly have to be for the calls to eventually succeed after a pause of 8 to 9 seconds... When something like this occurs I always assume there is a bug in my code until proven otherwise, but given (a) this code has executed properly for a very long time and (other than my diagnostic loop added) has not changed, and (b) it works in all environments except the win2k8 - win2k8 share, I'm guessing there is some OS issue in here that i do not understand. Any insight would be helpful. Thanks!
