  • Bad certificate error with RabbitMQ using SSL

    - by David Tinker
    I am trying to get RabbitMQ working with SSL on a couple of Gentoo servers. I get the following error in /var/log/rabbitmq/[email protected] when I try to connect to the management console using https: SSL: certify: ssl_connection.erl:1641:Fatal error: bad certificate I followed the instructions here: http://www.rabbitmq.com/ssl.html The annoying thing is that I have 2 cloned servers and it is working on one and not the other. As far as I can tell the machines are configured identically. I wrote a script to generate the certs etc. and have run it on both. I am not using client certificates. Anyone know how I can figure out whats wrong with my certificate(s)? I am using Erlang 15.2, RabbitMQ 2.7.9, OpenSSL 0.9.8k.

  • Windows Server 2008 R2 - What now?

    - by MrStatic
    So I installed Windows Server 2008 R2, I have Exchange 2010 running for some mail. I installed BlackBerry Enterprise Server Express for kicks. This server runs dns/dhcp for 2 laptops. But what now? It has 200g's free on the main drive and a 150g external that I have mapped as a network drive. I am not sure what else to do with this thing. It was my main station but since my laptop is nicer I am running it headless and using the lcd monitor for it as a second monitor for the laptop when I am at home.

  • kernel: journal commit I/O error

    - by jasondewitt
    I am having some problems with a Dell 1950 server. I am installing RHEL 4.6 along with Oracle and some other software on here. I am randomly getting an error message saying "kernel: journal commit I/O error" on my ssh session and on the monitor I have hooked up to the server I see an error scrolling by that says "EXT3-fs error (device sda5) in start_transaction: Journal has aborted." It has happened several times but never at the same point during the install. Actually, this last time the system was up and running and I was just trying to import a database into oracle. This has happened on several hard drives, so I'm pretty sure that is not the problem. This makes me think the raid controller is going bad. What do you guys think? ** UPDATE ** Pretty sure it was a bad hard drive. I threw another drive in the server and it's been running for about 48 hours with out problems.

  • Modify MDT wizard to automate computer naming

    - by Jeramy
    I originally posted this question to StackOverflow, but upon further consideration it might be more appropriate here. Situation: I am imaging new systems using MDT Lite-Touch. I am trying to customize the wizard to automate the naming of new systems so that they include a prefix "AG-", a department code which is selected from a drop-down box in the wizard page (eg. "COMM"), and finally the serial number of the computer being imaged, so that my result in this case would be "AG-COMM-1234567890" Status: I have banged away at this for a while but my Google searches have not turned up answers, my trial-and-error is not producing useful error messages and I think I am missing some fundamentals of how to get variables from the wizard page into the variables used by the lite-touch wizard. Progress: I first created the HTML page which I will include below and added a script to the page to concatenate the pieces into a variable called OSDComputername which, for testing, I could output in a msgbox and get to display correctly. The problem with this is I don't know how to trigger the script then assign it to the OSDComputername variable that is used throughout the rest of the Light-Touch process. I changed the script to a function and added it to DeployWiz_Initization.vbs then used the Initialization field in WDS to call it. I'll include the function below. The problem with this is I would get "Undefined Variable" for OSDComputername and I am not sure it is pulling the data from the HTML correctly. I tried adding the scripting into the customsettings.ini file after the "OSDComputername=" This resulted in the wizard just outputting my code in text as the computer name. I am now trying adding variables to "Properties=" (eg.DepartmentName) in the customsettings.ini, pulling thier value from the HTML Form and setting that value to the variable in my function in DeployWiz_Initization.vbs and calling them after "OSDComputername=" in the fashion "OSDComputername="AG-" & %DepartmentName%" in customsettings.ini I am rebuilding right now and will see how this goes Any help would be appreciated. The HTML page: <HTML> <H1>Configure the computer name.</H1> <span style="width: 95%;"> <p>Please answer the following questions.

  • Fedora 17 - Can't access remote machine using hostname

    - by Aaron
    I am using Fedora 17 and am trying to access a remote machine (running Fedora 15) using its hostname which isn't working. The machine is right next to me on the same switch as my machine (so they are both on the same network with the same subnet and everything). When I was running Windows (7 32-bit) on my machine I could access the other machine no problem but now that I am running Fedora 17 that's not the case. Is there an additional daemon or something that I need to be using in order for this to work?

  • Natively boot Virtualbox Image

    - by isync
    I am faced with a Windows hardware/software problem left over from another person. It's on me to resolve. It's a mission critical setup. The situation is: I've got a physical server machine with: -Disk C:\ (one disk) containing a basic install of Windows Server 2008 R2, formerly Win Vista Pro, now gone. -Disk D:\ (software Raid) containing a VirtualBox disk image of a configured Windows Server 2008 R2 running SQL Server R2 among others. What shall I do now? Migrate all the stuff from the configured VM to the basic but natively installed C:\ Windows Server 2008 R2 (with the possibility of breaking stuff)? Or, Setting up the machine to "natively boot" the VM with the help of bcdedit.exe (something I've read about, what I've never done, what I don't know of if it works, if it hits performance, or if it is stable for production) For me, being old skool, I am in the process of de-virtualising everything (option 1). But I'd be happy if someone suggests I am ok to go down the "natively boot" route.

  • over Windows terminal change cursor width or color in Vim depending on mode

    - by INTPnerd
    I am using PuTTY to connect over SSH to an Ubuntu server from my Windows 7 workstation. Once connected I am using the Vim installation from the Ubuntu server to edit files. I want the cursor to change when I go into and out of insert mode. Part of my .vimrc file is like this but it is not changing the cursor: if &term =~ "xterm" echo "xTerm!!inate!" let &t_SI = "\<Esc>]12;purple\x7" let &t_EI = "\<Esc>]12;blue\x7" endif I know that the if statement is executing because of the echo. EDIT: Actually I would prefer to change the cursor to be a vertical line like you can in the PuTTY settings rather than change the color, or maybe even do both. But just changing the color would be a lot better than nothing. Also I am willing to change terminals if there is another Windows 7 Professionsal 64 bit compatible terminal that can do this (preferably something free). Maybe Poderosa can do this?

  • Combine Multiple Audio Files into a single higher-quality audio File

    - by namenlos
    BACKGROUND My team gave a demo to a large audience - we recorded the audio of the demo in multiple locations in the room (3) the audio was recorded using cheap laptop microphones I was not involved in the recording of the audio or the demo Both audio files suck in some form the first one is of a recording near the speaker - which clearly gets his voice but the the audience is audience is muffled - also this one is slightly noisy The second recording was done in the middle of the audience - it gets the audience questions clearly but actually gets the speaker rather sometimes well and sometimes poorly (not all the speakers spoke loudly enough to be heard) MY QUESTION Is there any techinque or software which can be used to merge these audio files in such a way that the best qualities of each are preserved. I am NOT asking now to simply merge them together in one track - I've already done that in Audacity and it is certainly better - what I am looking for could be considered closer to how HDR images are created - multiple exposures combined into an enhanced new version which is not simply an average of the inputs. NOTE Am not an "Audio" guy - just a normal user

  • Apparent leak in Mozilla Firefox

    - by LeopardSkinPillBoxHat
    I use Mozilla Firefox 3.6 all day, opening and closing tabs quite regularly. I am noticing over time that the firefox.exe process size keeps growing and growing over time. Initially I put this down to memory fragmentation caused by opening and closing tabs, but now I am suspecting that there is a memory leak in one of the add-ons that I have installed. The problem I am seeing is that when the process size gets to about 1.5GB in the "Mem Usage" stat in Task Manager (and it gets there quite regularly), Firefox freezes up. Does anyone have any ideas about how I could diagnose whether: Any of the add-ons are leaking memory? Something else is causing this problem?

    Dear Everyone I am currently using openvpn for normal browsing. However, I have the following services running: a bit torrent client, a web server, IRC and a git server which I would really want it to not be using my vpn connection (and use my original connection instead). Is there a way to do this? I looked up policy routing and I can't really find any tutorial on how to do this on linux (I am on ubuntu). I don't want the solution to be incredibly complicated - I am pretty new to networking in ubuntu and I only want a very simple solution to this problem. Can someone help me out?

  • Setting up 802.1X wireless connection on OSX

    - by hizki
    I am an OSX user, I have Snow Leopard 10.6.5 and an updated AirPort. I am trying to connect to my university's wireless network, but it has a complex security that I am having trouble defining... Here there are instructions for connecting with Windows XP, Windows 7 and Linux. Can someone please instruct me what should I do to set up this network on my MAC? Thank you. P.S. I have had previous success in setting up this network, but I have no idea what I did that made it work. Since I updated my AirPort it worked only seldomly and very slowly... Before the update, even when it worked it never remembered my password.

  • Rework filename from mod_pagespeed back to normal files

    - by British Sea Turtle
    I am hoping someone can help me with this problem. I am moving to a new server and not using mod_pagespeed any more. However We not that we have lots of external links that link to images on our server using the strange mod_pagespeed filenames. This is not an issue but we do not want to have lots of 404 errors. So I have lots of links like the following : http://www.domain.com/images/150x150xlink.png.pagespeed.ic.pPXw45HSQm.png http://www.domain.com/images/paris_01.gif.pagespeed.ce.vfrkuKUaj0.gif http://www.doamin.com/images/1st2.gif.pagespeed.ce.OUg38q6VbZ.gif How can I redirect them to : http://www.domain.com/images/150x150xlink.png http://www.domain.com/images/paris_01.gif http://www.doamin.com/images/1st2.gif There are thousands of files like this so I am hoping for a simple solution with mod_rewrite, I tried this but it does not work. So any help would be appreciated. RewriteCond %{REQUEST_URI} \.gif\.pagespeed\. [NC] RewriteRule ^(.*?\.gif)\..*\.gif$ $1 [NC,L]

  • Remote monitoring with screen capture

    - by Anonymous
    Is there anyway i can perodically take screenshots of a remote computer using nagios? I am experimenting with Nagios, and i am trying to explore different monitoring. So my question is apart from using nagios to monitor cpu usage, bandwidth utilization, uptime etc.. can i monitor my worker's productivity by checking what is he doing on his computer in a form of image output. Being able to monitor processes would not be of much help to me, as i only know if he or she is running firefox.exe for example he maybe using excessive use of firefox for facebook or other stuff but he claims he is troubleshooting and looking for solutions on forums. I saw a check_vnc script but i am unable to install the requsite vnc server anyone succesfully tried the vnc script care to share how to go about it? If not anyother way to try this?

  • Where does Rundesk execute local tasks from

    - by Leon Stafford
    I'm trying to interact with the nodejs Azure sdk from a CentOS installation of Rundeck. If I try from the "run" adhoc virtual shell, I am able to after running azure account import <mykey> and can then also execute other Azure commands inside of jobs if I set them as Rundeck node tasks and not selecting "dispatch to nodes" in the job settings. Trying to run the Azure sdk commands as commands to be dispatched to the node (local) fails with the error: localhost1-NodeDispatch-localexec 04:53:04 /usr/bin/env: node: No such file or directory 04:53:04 Failed: NonZeroResultCode: Result code was 127 I am not able to "jumpstart" the same environment by running azure account import <mykey> I am assuming this is a permissions/environmental issue, though not sure how to fix it. UPDATE: Executing whoami from the same job returns rundeck, so I assume I will need to either modify that to execute tasks as my system user or grant permissions to get the rundeck user into the node environment the Azure sdk is running in?

I want to know how do web hosting companies give so many public IPs to so many users and each of them has root login also. How this is technically done that is what I am interested to know.

  • ITIL Incident Classification - Fault vs SR vs Technical Incident

    - by ExceptionLimeCat
    I am new to ITIL and Incident classifcations and I am trying learn more about them and understand how they could integrate in our organization. I have found it difficult to find a clear definition of Fault vs. Service Request vs. Technical incidents. I am basing my definitions on this article: http://www.itsmsolutions.com/newsletters/DITYvol6iss27.htm As I understand it: Service Request - Service provided by IT as part of regular administration of a system. Fault - An unexpected error in a system. Technical Incident - An interruption or potential interruption in IT service due to an expected incident caused by some IT policy.

  • windows server 2008 vs ubuntu 11 [closed]

    - by user472875
    I am working on implementing a custom server application that should be capable of handling a very large volume of traffic. I am aware that this type of question has been asked a lot, but I haven't been able to find a good answer. What I'm really looking for is for a server with given specs which OS will be able to handle a larger traffic faster and more reliably. I do not care about rights management or any other features. I am fairly good with both platforms, and so I would like to pick the OS with better performance on a clean install, and with nothing else running. Thanks in advance.

  • Random timeouts in IIS7

    - by Cor-Paul
    Hi, I have a weird problem which I think is caused by my IIS7 installation on Vista 64 bit. I have a bunch of AJAX calls and JS dynamic file loads (~30) in a local application, and I get random timeouts (or so it seems) in my browser. In Chrome it looks like the page just stops loading (no HDD activity), in Firefox/Firebug I can see that some of the files are being loaded but they never actually finish. When I reload the page the same occurs, but for (random) other files that must be loaded. When I try to load one of those JS files concurrently (so during the timeout in FF) in another browser, the file loads there. So I am pretty sure the request can be handled by IIS. I am thinking about a limit or so on simultaneous requests from the same browser which is not working correctly, but I am pretty clueless on how to solve this. Does anyone recognize this problem and know a solution? Thanks!

  • How to limit disk performance?

    - by DrakeES
    I am load-testing a web application and studying the impact of some config tweaks (related to disk i/o) on the overall app performance, i.e. the amount of users that can be handled simultaneously. But the problem is that I hit 100% CPU before I can see any effect of the disk-related config settings. I am therefore wondering if there is a way I could deliberately limit the disk performance so that it becomes the bottleneck and the tweaks I am trying to play with actually start impacting performance. Should I just make the hard disk busy with something else? What would serve the best for this purpose? More details (probably irrelevant, but anyway): PHP/Magento/Apache, studying the impact of apc.stat. Setting it to 0 makes APC not checking PHP scripts for modification which should increase performance where disk is the bottleneck. Using JMeter for benchmarking.

  • how to compile VTK on Mac Air

    - by Ilan Tal
    I am trying to compile VTK on a Mac after successfully doing so on Linux. I am using CMake 2.8.9 and for a long time I had a problem where it couldn't find jni.h. If anyone else has the problem, the answer is to have JAVA_INCLUDE_PATH2 point to "-framework JavaVM". After that it successfully finds JNI and does a "Configure" followed by "Generate". According to the instructions I have the next step should be easy: in a terminal run "make -j 2". I get a message "-bash: make: command not found". Strange.... I am in the vtkBuild directory, which seems the most reasonable place. I even tried the parent directory where I have the VTK source but that didn't work either. I ran a make under Linux and had no troubles, so what do I need to do with the Mac? Thanks, Ilan
