  • Why should one have a secondary DNS server?

    - by Sam Levin
    I'm very confused. I basically understand how DNS works. Here's an example that helps illustrate what I'm having trouble understanding. Right now, I run a small web-server. I use my provider's DNS manager, so I don't have a DNS server hosted on the machine. Let's say for a second, that I don't use my host's DNS, and I decide to set up a DNS server on my server. Hypothetical scenario: my server (entire) server goes down - DNS included. Why do I need backup DNS? If the server is down, who cares if the DNS server is down too, considering that even if I had DNS up (it wasn't on the crashed server), it wouldn't be able to forward requests anyway since the server would be down? Is the point of having secondary DNS, to be able to change the IP addresses that your DNS server points to, so if your webserver was down, you could redirect traffic to a backup? How would you switch to the secondary provider, in the event that your main DNS provider becomes unavailable? Is a backup DNS system basically up all the time? How is it configured? Is it just an exact clone of the DNS server you would have on your server? Do they run simultaneously? Hopefully someone can see what I'm hung up on, and provide some guidance. Thanks

  • 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

  • Sharepoint Workflow "Failed on Start" only when powershell import script is called from task scheduler

    - by Matt Keller
    I created a simple PowerShell script that takes an XML file in a local directory on our sharepoint server and imports it into a specific SharePoint form library. (Content management enabled library if that makes any difference) This script works flawlessly if i run it from the PowerShell command line manually. I call it like such: ".\script_name.ps1". It completes without error and the item is imported into the form library successfully. The workflow begins on the item and everything is happy dandy. However, i run into issues when i setup a scheduled task using Windows Server 2008 R2's task manager. The task runs the script without error and it does actually import the XML into the form library. I looks perfectly normal just as if i had run the script manually. However, after about 10 or 20 minutes the workflow status for that item changes from "In progress" to "Failed on Start (Retrying)". The scheduled task in question is a basic task and has only one action. (Start a program) The "program/script" box is set to "C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe" and the "Add arguments" box is set to the path of the actual ps1 script. (C:\scripts\sharepoint_import.ps1) I've tried running the task as various users. I've also tried with and without the "Run with highest privileges" check box. Nothing seems to work. For reference, here is the script i am using to import items into the form library.

  • Windows SBS 2008 to Windows Server 2012 migration

    - by StefanGrech
    I am in the process of upgrading my Windows SBS 2008 server running Exchange, Active Directory and as a File server to Windows Server 2012 essentials. Now I know that Windows Server 2012 essentials does not have exchange, thus I was looking to migrate the Active directory and the file server to Windows Server 2012 essentials, Then I would have a separate Virtual machine running Windows server 2012 standard with Exchange 2013. Now my question is, what should I do first? Migrate the AD and File server to Windows 2012 essentials and then after the migration is finished, I create a local move of the mailboxes from SBS 2008 to Windows Server 2012 standard running exchange 2013? or should this be the other way round?

  • windows 2008 always keep local dns in first

    - by user3085220
    I have a windows 2008 system and it always keep ::1 in first of the dns setting. I can see the following in "ipconfig /all": DNS Servers . . . . . . . . . . . . : ::1 8.8.8.8 8.8.4.4 and "Obtain dns server address automatically" option in network interface setting is disabled. I installed active directory once and uninstalled now, I think it's the reason. But I can't find any answer from google or bing how to fix.

  • /usr/bin/python (Python 2.4) was deleted on CentOS 5. I compiled from source but yum is still broken. How can I get everything back to the way it was?

    - by Maxwell
    I saw a lot of other questions like this but none of them answered the exact part I am having trouble with (actually installing the Python RPM). Someone on my system deleted /usr/bin/python and /usr/bin/python2.4 on my 64 bit CentOS 5.8 installation. I recompiled Python 2.4 from source, but now whenever I try to yum install anything I get the following error: [root@cerulean-OW1 ~]# yum install httpd There was a problem importing one of the Python modules required to run yum. The error leading to this problem was: No module named yum Please install a package which provides this module, or verify that the module is installed correctly. It's possible that the above module doesn't match the current version of Python, which is: 2.4 (#1, Dec 16 2012, 09:16:56) [GCC 4.1.2 20080704 (Red Hat 4.1.2-52)] If you cannot solve this problem yourself, please go to the yum faq at: http://wiki.linux.duke.edu/YumFaq I checked http://wiki.linux.duke.edu/YumFaq and it said the following: If you are getting a message that yum itself is the missing module then you probably installed it incorreclty (or installed the source rpm using make/make install). If possible, find a prebuilt rpm that will work for your system like one from Fedora or CentOS. Or, you can download the srpm and do a rpmbuild --rebuild yum*.src.rpm I tried going to http://rpm.pbone.net/index.php3/stat/4/idpl/17838875/dir/centos_5/com/python-2.4.3-46.el5.x86_64.rpm.html to install Python, which resulted in the following error: [root@cerulean-OW1 ~]# rpm -Uvh python-2.4.3-46.el5.x86_64.rpm error: Failed dependencies: python-libs-x86_64 = 2.4.3-46.el5 is needed by python-2.4.3-46.el5.x86_64 So I tried installing python-libs-x86_64, which resulted in the following: [root@cerulean-OW1 ~]# rpm -Uvh python-libs-2.4.3-46.el5_8.2.x86_64.rpm warning: python-libs-2.4.3-46.el5_8.2.x86_64.rpm: Header V3 DSA signature: NOKEY, key ID 192a7d7d Preparing... ########################################### [100%] package python-libs-2.4.3-46.el5_8.2.x86_64 is already installed file /usr/lib64/libpython2.4.so.1.0 from install of python-libs-2.4.3-46.el5_8.2.x86_64 conflicts with file from package python-libs-2.4.3-46.el5_8.2.x86_64

  • nsclient++ intermittent connection refused on same subnet

    - by jshin47
    I have setup Nagios and nsclient++ on a number of my Windows servers. They are all in the same subnet so no routing or firewall stuff is taking place in between the endpoints, and I have verified that the firewalls on the servers are not causing trouble. The problem is that the scheduled checks sometimes fail with "connection refused" and sometimes work! It is a frustrating problem to resolve because I do not know what to look for. One place I did look is in the nsclient++ logs, where I am seeing this recurring error: ...\trunk\modules\CheckSystem\PDHCollector.cpp:148: Failed to query performance counters: \238... This sounds promising, but I couldn't find much on Google about this error as it pertains to NSClient++

  • Windows Authentication with IIS7 with public facing website

    - by user38553
    By default in IIS7, Windows Authentication was turned off and I had to make a configuration change to activate it. When I did that there was a description for Windows Authentication that explained this should only be used for intranet sites, not public facing websites. When you consider NTLM/Kerberos does not use plain text I am not sure why Microsoft have decided this, all of a sudden. Can anybody explain?

  • IIS7 Compression Configuration

    - by Level1Coder
    Hi, Previously when I used IIS6, I used IIS6 Metabase Explorer to edit Metabase.xml and manually turned on compression, specified the compression level and the file extensions to compress. IIS7 seems a bit different, there is no Metabase.xml file in the system32\inetsrv folder. Enabling compression is easy to turn on by checking the checkbox in the Compression module. But how do I manually tweak and set the compression levels and file extensions to compress? I also ran across an article saying that IIS7 also automatically throttles the compression if your CPU load is 50% then compression is turned off. Where are all these settings located?

  • www.domain.com and domain.com records in microsoft dns

    - by captainmish
    Hello Apologies if this is already answered, its a tricky one to search for! We are using split DNS for a domain used internally. For the outside nameservers, theres a simple zone with: @ IN A ip.ad.dr.ess www IN A ip.ad.re.ss This works fine externally. Internally its a windows server 2003 DNS server, so the www a record works fine, but I cant figure out how to add that primary record (using at symbol @ in bind). Can anyone help with how to get the same results from windows dns? I just want to be able to add a record for domain.com without being forced to use something.domain.com Thanks, Edit: This domain is not the "main" AD domain, and not used for logins etc.

  • Identifying cause of Software opening hundreds of thousands of handles

    - by user428370
    I have a user running the latest public revision of IBM Notes (8.5.4) on a Windows 7 Pro OA installation. Under his profile and only his, when the software is run, the software opens hundreds of thousands of handles, regarding token queries. This involves only this specific user, on his computer, using only said software. I have narrowed down the issue to being related to his profile but am unsure of what to look at next. Any advice would be appreciated.

  • httpd Redirect / Rewrite .com to .org

    - by David W
    I am trying to redirect a www.example.com to www.example.org. I cannot figure out what I'm doing wrong. I have ensured that mod_rewrite is enabled in httpd.conf with: LoadModule rewrite_module modules/mod_rewrite.so I further verify this by running: httpd -M and getting rewrite_module (shared) included in the results. Later in the same httpd.conf file is the VirtualHost directive where I am trying to perform the rewrite: <VirtualHost *:80> Options +FollowSymlinks RewriteEngine On RewriteCond %{HTTP_HOST} ^example.com [NC] RewriteRule ^(.*)$ http://www.example.org/$1 [R=301,NC,L] ServerAdmin [email protected] DocumentRoot /var/www/html ServerName example.org ServerAlias www.example.org *.example.org <Directory "/var/www/html"> Options Includes FollowSymLinks AllowOverride All Order allow,deny Allow from all </Directory> ErrorLog /var/www/logs/error_log CustomLog /var/www/logs/access_log common </VirtualHost> As we can see, we are following SymLinks in the directory (which I believe is a requirement), AND we allow All Overrides (which meets another requirement). But obviously I'm still doing something wrong. Can you spot it?

  • How can we achive a 403 Permissions Denied for a subdomain?

    - by marikamitsos
    We have a multisite installed in the root directory (multisite.com) and also a wordpress single installation on a subdomain (help.multisite.com) In the root .htaccess we placed: #START Security: Disallow access to folders Options All -Indexes # END Security On the main site (as expected we get) "403 Permission Denied. You do not have permission for this request /wp-content/blogs.dir/83/" Nice. :) BUT. We just noticed that when trying to access the subdomains folders we get: Internal Server Error. The server encountered an internal error or misconfiguration and was unable to complete your request.... Additionally, a 500 Internal Server Error error... This is something we do NOT want. So the question is: How can we avoid the above result and make the message for the subdomains be "403 Permission Denied" (the same as for the main site and NOT "500 Internal Server Error" (as it is now)? We put what, where?

  • Difference between *:80 and _default_:80 in Apache2

    - by Johannes Ernst
    I'm trying to understand the difference between the following two terms: *:80 _default_:80 in the Apache configuration file. The documentation here is unclear to me, and the only mailing list conversation that I could find here does not shed any (comprehensible, to me) light on the matter either. I have a bunch of name-based virtual hosts declared like this: <VirtualHost *:80> ServerName example.com ... and I'd like to have an entry that fires when none of those match, i.e. when a request comes in without a virtual host name, or with a virtual host name that has not been declared. Should I use *:80 or default:80?

  • bash : "set -e" and check if a user exists make script exit

    - by Dahmad Boutfounast
    i am writing a script to install a program with bash, i want to exit on error so i added "set -e" in the beginning of my script. the problem is that i have to check if a user exists inside of my script, to do this i am using "grep "^${USER}:" /etc/passwd", if the user exists, the script runs normally, but if the user doesn't exist, this command exists, and i don't want to exit on this case (i have to create the user and continue my installation). so what's the solution to make my script continue running ?? i tried to redirect the output of "grep" to a variable, but i still have the same problem :( thanks.

  • Access Amazon Linux EC2 over VNC using Guacamole

    - by Neon Flash
    I have a t1.micro Amazon Linux AMI instance running. Now, I want to access it using VNC so that I get the GUI. I came across Guacamole and the installation instructions for the server side configuration. So, I get it that we need to setup Apache Tomcat on the Linux machine and then install all the required dependencies, edit the configuration files for Tomcat. But, how do I access it from Windows? What is the client side configuration? From what I understood so far, instead of using a VNC Client like TightVNC or VNCViewer, we can use the Web Browser to access the Amazon EC2 instance. I am using Windows 7 as the client. I would like to access the Amazon Linux AMI (t1.micro instance) over VNC so that I get the GUI.

  • cygwin sshd fails to allocate pty for some users

    - by user115851
    I have (finally) got sshd working under cygwin on Win7 - well, sort of. The sshd runs as user 'cyg_server'. I'm able to successfully ssh to my computer using that same user name. However, if I attempt to ssh using my normal (Windows) user name, it fails trying to allocate a pty for my login session. For example, output of 'sshd -D -d -d -d' contains this .. ... debug1: Entering interactive session for SSH2. debug2: fd 4 setting O_NONBLOCK debug2: fd 5 setting O_NONBLOCK debug1: server_init_dispatch_20 debug1: server_input_channel_open: ctype session rchan 0 win 1048576 max 16384 debug1: input_session_request debug1: channel 0: new [server-session] debug2: session_new: allocate (allocated 0 max 10) debug3: session_unused: session id 0 unused debug1: session_new: session 0 debug1: session_open: channel 0 debug1: session_open: session 0: link with channel 0 debug1: server_input_channel_open: confirm session debug1: server_input_global_request: rtype [email protected] want_reply 0 debug1: server_input_channel_req: channel 0 request pty-req reply 1 debug1: session_by_channel: session 0 channel 0 debug1: session_input_channel_req: session 0 req pty-req debug1: Allocating pty. debug1: session_pty_req: session 0 alloc /dev/pty1 !!! chown(/dev/pty1, 17308, 10513) failed: Invalid argument debug1: do_cleanup debug1: session_pty_cleanup: session 0 release /dev/pty1 Currently /dev is owned by my normal account. I've tried changing its ownership to cyg_server as well as SYSTEM. In both cases the problem persists. I've also changed permissions for /dev (e.g, 700 and 777) - again problem persists. [As a side note - it is strange that whenever I do 'ls -al /dev' the ptys do not show up. However, if I 'ls -l /dev/ptyX' for a pty I know to exist, it shows up. Is that normal for cygwin?] -Bob Andover, MA

  • Netstat flags on OS/2

    - by Cian
    On an OS/2 box, what do the flags UGDP mean in the output of netstat -r. Google seems to point to them meaning Up, Gateway (i.e. an indirect root), and Dynamic (learned from a redirect), but that leaves me mystified as to the meaning of P. The only suggestion I've had is permanent but that doesn't make any sense with dynamic. Any ideas?

  • Oracle tuning optimizer index cost adj and optimizer index caching

    - by Darryl Braaten
    What is the correct way to set the optimizer index cost adj parameter for Oracle. As a developer I have observed huge performance improvements as this parameter is lowered. Common queries are reduced from 2 seconds to 200ms. There are lots of warnings on the net that lowering this value will cause dire issues with the database, but no detail is given on what will start going wrong. I am currently only seeing only an upside, much improved application performance and no downside. I need to better understand the possible negative repercussions of adjusting these parameters.

  • IIS7, different ports for websites but no portnumber in the browser

    - by Queensheep
    I have a windows server 2008 with IIS7 with 4 websites. In DNS I have 4 different URLs which point to the IP of the server. I configured each web site with the site bindings: website1: hostname: url1, port: 80, IP-Adresse: the adress of the server website2: hostname: url2, port: 80, IP-Adresse: the adress of the server The result is, that from the client, I can browse with all the 4 URLs to the specified web sites and everything is fine. Then I changed in IIS the port of the websites, so that website1 now uses port 8080, website2 uses port 8081, and so on. Now I have to use the browser with the url and the portnumber (like URL:8080). Is there a possibility, to configured the websites with different portnumbers but not to use the portnumbers in the browser?

  • Problem with Nobody and PhP

    - by user39190
    We use Cpanel/WHM and have just used EasyApache to upgrade to Apache 2.2 and PhP 5.3.2 As a result of the upgrade process, the user "Nobody" who runs php can no longer access directories or create directories in the various owners web directories. For instance, with Word Press we can no longer upload images. We have tried rebuilding with SuEXEC on and off, SuPHP on and off and nothing makes any difference. It feels as if the user "Nobody" has got its permissions messed up, but that is a wild guess. How can we get back to where we started which is, I assume, that "Nobody" had the rights to the file systems in the web directories?

  • hosting environment for delivering FLVs

    - by Gotys
    What would be the ideal hardware setup for pushing lots of bandwith on a tube site? We have ever-expanding cloud storage where users upload the movies, then we have these web-delivery machines which cache the FLV files on its local harddrives and deliver them to users. Each cache machine can deliver 1200 mbits/s , if it has SAS 8 harddrives. Such a cache machine costs us $550/month for 8x160gb -- so each machine can cache only 160GB at any given time. If we want to cache more then 160gb , we need to add another machine..another $550/month..etc. This is very un-economical so I am wondering if we have any experts here who can figure out a better setup. I've been looking into "gluster FS", but I am not sure if this thing can push a lot of bandwith. Any ideas highly appreciated. Thank you!
