• Configure Nagios To Alert Depending On Host Group That Service Alert Originates From

  - by StrangeWill

  So my setup: Services are shared between all hosts (CPU/RAM/Disk/Services). Hosts are split into two main groups: "Production" and "Development". We have two contact groups: "Production" and "Development". Lets say my development SQL server runs low on RAM, I want it to only alert those in "Development" contact group (this service is of course assigned to a host in the "Development" host group, using the shared RAM monitoring service). I'm pretty much stumped on this... I can't configure it at the service level (they're shared there), and I can't seem to get escalations to do it for me either... Do I need to use service groups along with escalations and bite the bullet on building that list? Or am I missing something stupidly simple? I'm using Centreon for configuration if that helps.

• Motherboard on, but nothing will start

  - by Geeklat

  I'll try and be as clear as possible. Recently I purchased a barebones kit for my first attempt at a full PC assembly. I've gone through and connected all the parts correctly based on numerous examples that confirm everything is connected correctly. The motherboard and the video card are receiving power based on the fact that the motherboard's power LED is on and the video card has some LEDs on. Nothing else in the computer will come on when pressing the power button on the case. No fans, no hard drive, no CPU fan. Not even for a split second. I also receive no beeping noise from the speaker connected to the motherboard. I've also tried swapping the reset and power connectors from the front of the case to no luck.

• Vim: Show the index of tabs in the tabline

  - by bitmask

  Lets say I opened file1.txt, file2.txt, file3a.txt and file3b.txt such that the tabline (the thing on the top) looks like this: file1.txt file2.txt 2 file3a.txt (Note how file3b.txt. is missing because it is shown in a split, in the same tab as file3a.txt) To move more quickly between tabs (with <Number>gt), I would like each tab to display its index, along the filename. Like so: 1:<file1.txt> 2:<file2.txt> 3:<2 file3a.txt> The formatting (the angle braces in particular) are optional; I just want the index to appear there (the 1:, 2: and so on). No clues on :h tab-page-commands or google whatsoever.

• Should I remove all unmanged switches from my network?

  - by IMAbev

  I have a office network with approx 150 devices (computers/printers/ip phones). Almost all of the end point devices have straight run Cat5e from my Hp switches directly to the device. IP phones for each end user sit between the hp switch and computer. (hp switch - in to phone out of phone in to computer) While I have gotten rid of most of them, I still have a couple linksys unmanaged switches that split off to 2 or more devices. I have heard various reasons for removing these switches but not entirely sure if it actually degrades the network. I agree that eliminating these switches certainly cleans up the network from a management standpoint. Are these unmanaged switches bad for my network? Is there a clear advantage to having 'home run' cable runs to each of my end point devices?

• DrayTek Vigor 2920(n): VPN with VLAN restrictions?

  - by Dirk

  Hi, I'm currently installing a DrayTek Vigor 2920n router in a new office. This router is to be used for 2 seperate companies. For one of these companies, the router has a LAN-2-LAN (VPN) connection to a datacenter configured. The other company should not be able to access this other (VPN-)network. I'm aware of the capability of this router to have VLAN's, but I cannot figure out how to configure the VPN-connection to only be accessible for VLAN0 and not for VLAN1. I know I can also add another router to physically split both networks, but we bought the DrayTek with the idea that it could easily have the VPN-connection available for VLAN0 and not for VLAN1. VLAN1 can easily be in another subnet, that's fine, although, I don't know how to configure that on this DrayTek. Can anyone point me in the right direction? Thanks in advance, Dirk

• Cisco VPN Solution [on hold]

  - by Joey Harris

  Not sure if I can ask this type of question here so please delete if it should not be here. Im building a small server environment for a company and they are going to require a VPN gateway to connect to a main office from potentially anywhere in the world. I was hoping somebody could give me a recommendation on a Cisco product that can offer VPN connectivity for up to 100 clients and supports split tunneling. All products I've looked at are a few thousand dollars. I'm hoping someone can find me something that's only a few hundred dollars. I've seen the VPN Concentrator series but the modals that aren't thousands of dollars only support 4Mbps throughput. There will be file transfers going on so I'm hoping for something more then 500KBps.

• IBM Tivoli Network Manager IP Edition - Job does not run

  - by Thorsten Niehues

  Since our network discovery takes too long I tried to split the biggest job into two parts. The two parts use the same Perl script but have a different scope. I copied a Job (Agent) doing the following: Copied the .agnt file Copied the associated perl script The problem is that one or the other job (changes randomly) does not run. The Disco Process will fail eventually. In the log of the job which does not run I see the following error message: Wed Jul 18 08:48:54 2012 Warning: Failed to send on transport layer found in file CRivObjSockClient.cc at line 1293 - Client My_MacTable_Cis is not connected to service Helper How do I fix this problem?

• Windows 2003 DNS updates from ISC DHCP server

  - by wolfgangsz

  We have a very mixed network, with most clients being Debian Lenny, the rest Windows XP/Vista/7. The network itself is split into two segments (for technical reasons) called "corporate" and "engineering". On the "corporate" side all clients get their IP addresses from a Windows DHCP server and the dynamic updates into the Windows DNS work just fine. On the "engineering" side, clients get their IP addresses from a linux machine running the standard ISC DHCP server. Although this server is configured to do dynamic DNS updates, they actually don't work. Anybody got any advice on how to fix this? Please note: dynamic updates from the clients directly into the DNS would work, but are not an option for us. So this is strictly on how make this work from an ISC DHCP server to a Windows DNS server.

• Migrating data from SQL Server 2000 to SQL Server 2005

  - by Muhammad Kashif Nadeem

  I have to migrate existing data which is in SQL Server 2000 to SQL Server 2005. The schema of two databases is different. For Example Locations table in SS2000 is split into two tables and has different columns. This is one time activity. After successful migration I don't need old db anymore. What is the best way to transfer data from one SQL Server to another having different schemas? I can write stored procedures to fetch data from SQL Server 2000 and insert/update tables in SQL Server 2005. What about SSIS? I don't have any experience with this and is this better to create package of SSIS because I don't need this again and need to learn it first. Thanks.

• MS Project - Schedule short duration tasks that stay within working hrs

  - by Dave Warwick

  I am planning a series of tests that take a couple of hours each. However, you can not split a test so I do not want the next test to begin if there is not enough time within the specified working hours of the day to complete it. Also, I would like to begin each day with a set-up period before the actual testing can begin. Is there a way to automatically begin each day with a setup period and have tasks that can not complete before the end of the specified work day defer starting until the next day?

• Create Hidden Partition on USB

  - by Francesco

  I need to split an USB flash disk into two USB drives, each one with its own drive letter, but one of these has to be hidden. In the non-hidden partition I want to place my software, and in the hidden partition I need to place some files that are required by the software in order to work. Moreover, only the software may read, write, delete or execute the files in this partition. I thought to use a little partition viewed as a CD-ROM drive, as they do in many flash drives, but this solution does not allow to write other data in a second moment, and it's visible to the user that can read the file. Obviously the software must be able to access to partition and read, write, delete or execute the content. Is there a solution to do so, possibly that work also on Linux?

• How to change from own Internal/Extrernal DNS to use an outsourced service like DNS Made Easy?

  - by Joakim

  Our current setup is a co-located linux box with an openvz kernel with a handful virtual containers for www, mail etc. and one container run Bind9 with a split views configuration serving External and Internal DNS. The HW-Node runs a shorewall firewall and all containers uses private ip's. The box (and DNS) basically handles web and mail for a handful domains and it works well but we still think it would be a good idea to outsource the public DNS and now to my question... Although I am fairly comfortable with the server stuff and DNS, I'm far from a pro and guess I basically need some confirmation that I am thinking in the right direction in that I basically just move the content of our external view (with zone files) to the external service and keep the internal view (or actually remove the view), update the new external DNS with thier names servers, update the info at my registrar and wait for propagation or have I missed something? Maybe someone else here run something similar already and can share some exteriences? I found this question which at least confirms it can be done.

• Perl script and out of memory errors

  - by Kevin

  We have a midsized server with 48GB of RAM and are attempting to import a list of around 100,000 opt-in email subscribers to a new list management system written in Perl. From my understanding, Perl doesn't have imposed memory limits like PHP, and yet we are continuously getting internal server errors when attempting to do the import. When investigating the error logs, we see that the script ran out of memory. Since perl doesn't have a setting to limit the memory usage (as far as I can tell) why are we getting these errors? I doubt a small import like this is consuming 48GB of ram. We have compromised and split the list into chunks of 10,000, but would like to figure out the root cause for future fixes. This is a CentOS machine with Litespeed as the web server.

• Classic ASP on large memory server

  - by Steve Evans

  I have a client with a large ASP app that apparently is fairly memory intensive. I’m helping them migrate to new hardware they have running Win2k8 R2. They have 4 physical servers with 32gb of RAM each. I’m making the assumption that ASP apps run as a x32 process. So I see that we have two options: On the application pool enable web gardens. Use the physical servers as VM hosts and split the box into say 4 web servers each. Any thoughts on which path will provide us better performance? I’m just not really sure how ASP will handle a machine with lots of memory, and I’m worried it won’t really be able to address the memory well. (you can ignore all the obvious stuff like increased maintenance of 16 web servers vs 4, or the flexibility virtualization gets us over physical servers, etc)

• Apple XRaid questions

  - by luckytaxi

  I inherited an environment with a couple of apple xraid san. 1 - I have a 14 drive setup that's split into 5 LUNs on EACH side. The SAN goes into a fibre switch along w/ the servers that are attached to it. LUN masking is enabled on the SAN and as far as I know, there aren't any zoning on the fibre switch. Question, I have a server that's assigned two LUNs, one from each side of the controller. For some reason, it only sees one LUN (from the upper controller) and it doesn't see the one from the lower controller. The controller seems to be working fine as I have other servers attached to LUNs on the lower controller. 2 - I see a little "disclaimer" saying that any changes to the xraid will result in a reboot. So, if I add/remove hosts, this thing is going to reboot?!?!?!

• Recovery of Pinnacle Studio Project Files

  - by seanieb

  My external hard drive had some sort of issue a few months ago, but I was able to recover my files using a data recovery software program. However my Pinnacle studio files are not being recovered as before, they are being recovered as directory's/folders that have sub directory's and files. And I have tried with several different recovery programs and they all recover the projects as directories. And the projects all contain one file called README.TXT: * WARNING This directory contains the descriptive data of the project, split into. various subdirectories and files for better access. DO NOT EDIT, ADD, CHANGE OR MODIFY ANY OF IT'S CONTENTS! This gives me hope that I could some how just turn the directory into a .stu Pinnacle studio project file. How would I go about doing this? Or is there another way to solve this problem?

• Server Fault Wiki: How does Subnetting Work?

  - by Kyle Brandt

  How does Subnetting Work, and How do you do it by hand or in your head? Can someone explain both conceptually and with several examples? Server Fault gets lots of subnetting homework questions, so we could use an answer to point them to on Server Fault itself. If I have a network, how do I figure out how to split it up? If I am given a netmask, how do I know what the network Range is for it? Sometimes there is a slash followed by a number, what is that number? Sometimes there is a subnet mask, but also a wildcard mask, they seem like the same thing but they are different? Someone mentioned something about knowing binary for this? Not looking for links to other sites (unless maybe you have one post with a bunch of good ones). I already know how to subnet, I just thought it would be nice if Server Fault had a generic subnetting answer.

• Windows 8 slow after refreshing and rebooting

  - by Dan Drews

  First, I apologize if this is in the wrong place. I use S/O a lot but not the other sites much. I have an HP Split X2 that has been very choppy as of late (takes several seconds to respond to any form of input), so I went ahead and did a system refresh. After the refresh everything ran very fast as it should, then when I went to download my old apps I needed to reboot. After rebooting, it went back to the choppiness. Does anybody have any thoughts on what this could be?

• Music but no voice on headphones

  - by TFD

  I have normal stereo headphones which work fine On a specific PC running Windows 7 the external speaker and USB speakers work fine too But when I plug in the headphones, all I hear is muffled music, no voice track? It sounds like it is being split into 5.1, and I am getting just the L & R components, and not the centre voice channel? In the Playback devices (sound) control panel, I can adjust stereo or 5.1 for external speakers or USB speakers, but not for the headphones. The config button is grey out for them Is this the problem, if so how do I fix it?

• When your field-terminating char appears within field values

  - by Jonathan Sampson

  I've had a very colorful morning learning the innerparts of Linux's sort command, and have come across yet another issue that I can't seem to find an answer for in the documentation. I'm currently using -t, to indicate that my fields are split by the comma character, but I'm finding that in some of my files, the comma is used (between double-quotes) within values: Jonathan Sampson,,[email protected],0987654321 "Foobar CEO,","CEO,",[email protected],, How can I use a comma to terminate my fields, but ignore the occurences of it within values? Is this fairly simple, or do I need to re-export all of my data using a more-foreign field-terminator?

• IPSec tunnel between FortiGate and iPhone / iOS - Works except for DNS / Wins

  - by user57988

  I have configured my Fortigate with a new VPN IPSec tunnel to allow the iOS Cisco client to connect. That works fine. I can RDP to my servers, browse to my servers via IP address, etc. But, the iPhone does not resolve my internal IP addresses. I have added the DNS servers that serve addresses for my internal users, as well as the WINS servers, but the iPhone acts like it doesn't see them at all. config vpn ipsec phase1-interface edit "iPhone_VPN" set type dynamic set interface "wan1" set dhgrp 2 set proposal 3des-sha1 3des-md5 set xauthtype auto set mode-cfg enable set authusrgrp "iPhone_VPN_Users" set ipv4-start-ip 10.10.99.100 set ipv4-end-ip 10.10.99.199 set ipv4-netmask 255.255.0.0 set ipv4-dns-server1 10.10.2.1 set ipv4-dns-server2 10.22.1.80 set ipv4-wins-server1 10.10.2.1 set ipv4-wins-server2 10.22.1.80 set ipv4-split-include "Dialup_VPN_Networks" set psksecret ENC xxxxx next end For whatever reason, as far as I can tell, the iPhone does not 'see' the DNS or WINS entries. I don't know how to check it...

• 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.

• Why is my Mac beeping at me in a Sprint-Nextel-PTT kind of way?

  - by Philip

  I'm really stumped about this one. Before on OSX 10.5 and now on OSX 10.6, my Mac occasionally beeps at me. It's a split-second "bee-bee-beep" that sounds vaguely similar to the push-to-talk beep you hear on Sprint/Nextel PTT commercials. I haven't been able to isolate what's running when it happens or what happens before it happens. Possible culprits are Quicksilver, Firefox, DropBox, Evernote helper, TrueCrypt, Wally. Any thoughts? Thanks.

• Kindle 2 and PDFs in landscape

  - by doronkatz

  Hi guys, I am looking at getting a Kindle 2, read a lot about the PDF support (or lack off) and wanted to ask someone who has a kindle, a question. If you read a pdf in landscape mode, does it shrink the text to have it all in the one screen, or does it increase font size and split it into two or more pages. I have another reader, the iRiver Story and it does that, splits it into multiple pages thus making it readable. I know you can't zoom or anything like that in portrait view (i assume) I know you will say stick with iRiver, but the make of the kindle is a lot better (metallic back) and its useful to have a hybrid amazon book/pdf reader in one.

• Splitting CA component off puppet master

  - by Dennis LeMioux

  We are scaling our puppet infrastructure and would like to split off the CA component from the puppet master server to another server. Part of the change involves a servername change for the puppetmaster too. I'm no puppet expert but i'm at a point where I -think- we need to create a SAN cert with both the old and new names in it (to be safe), and then re-sign all the agent nodes all over again which is going to be a royal PITA. Is there a quicker/smarter way to do this? We already have hundreds of agent nodes out there and individually re-signing them will be an arduous task.
