• Configure all hosts, then create a list of the config for all hosts?

  - by AME

  I deployed a huge number of hosts with Ansible - which did work very nice. Each host got its individual settings and configuration. Now I'd like to generate a config file for another system that uses these hosts. For it, I need for every host a part of the generated configuration (the one that configures the database). Here is an example of the situation with two hosts having different configuration and the other system that uses a part of the Ansible-generated configuration: host1 ansible configured dbA host2 ansible configured dbQ The other system: host1 = dbA host2 = dbQ The values are computed differently (dbQ instead of dbB for host2 for example) if it belongs in a different cluster and so on, making it unpractical to just read out host configuration from the host_vars. I believe I would need to iterate over the hosts and let Ansible figure out the computed values for the variables like it would when deploying, but I do not know how to put that result in one template. Please advise :)

• Dell Dimension running Fedora12 does a "Sleeping Beauty" and I am not am not a "handsome prince"!

  - by Jim Dobbs

  Dell Dimension 2350 with a Pentium IV processor and integrated video and network chips running Fedora12 does a "Sleeping Beauty" and I, apparently, am not am not a "handsome prince"! The system puts video and network to sleep and it will not wakeup. I have heard of this problem on laptops, but this is a tower. Any ideas or help is appreciated. I tried to ping the network card from another system and ping fails. The logs indicate that the system continues to be active. Pressing keyboard short-cut keys makes the disk light blink but neither the video or network card comes alive. Failing all else, are there any Linux commands that I could schedule in cron to pulse video and network adapters hourly that will keep them awake? Or, should I wait on Fedora13? Before this machine, I built a Dimension 2400 with Pentium IV and it had the same problem. Fedora9 on the same hardware is fine.

• what damage can be caused if scandisk is not run before defrag

  - by Justin Gregoire

  Hello, I would like to know what the damage to a drive can be if a scandisk is not performed before a disk defrag. I have looked up some sites that say a scandisk should be run to correct any issues that may be apparent on the system, making sure that the drive is free of errors before a disk defrag is done. I have to perform a defrag on a computer without having physical access to it (using remote connection). I know that the scandisk requires a reboot to the system (causing me to lose my connection) which would be difficult to restart physically if the system does not come back on by itself once rebooted (this has happened before). Any suggestions? Thank you.

• Sun Java keytool importing EV certificates into a single keystore

  - by ss0

  At my current job we are using tomcat, customers have custom web portals setup on their own local machines. EV certs are new to me, they have 2 part intermediary and a primary certificate. For our product to work it appears I need to get all three parts installed under a single keystore entry. How can I roll all three parts into a single x.509 compliant file for import? They syntax I am using is as follows: /blah/system/j2sdk/bin/keytool -import -alias foo -keystore /zix/system/jdk1.5.0_06/jre/lib/security/cacerts -file certname.pem -trustcacerts where foo = the keystore name and certname.pem is the main cert. I have tried importing the intermediate certs under their own names into the keystore and I don't know if it's just the product I have to work with (not vanilla tomcat) or what but it doesn't see those. I have seen a working system and all three certs were under the single keystore alias. Anyone have any ideas?

• Simple one-way synchronisation of user password list between servers

  - by Renaud Bompuis

  Using a RedHat-derivative distro (CentOS), I'd like to keep the list of regular users (UID over 500), and group (and shadow files) pushed to a backup server. The sync is only one-way, from the main server to the backup server. I don't really want to have to deal with LDAP or NIS. All I need is a simple script that can be run nightly to keep the backup server updated. The main server can SSH into the backup system. Any suggestion? Edit: Thanks for the suggestions so far but I think I didn't make myself clear enough. I'm only looking at synchronising normal users whose UID is on or above 500. System/service users (with UID below 500) may be different on both system. So you can't just sync the whole files I'm afraid.

• What are the things to look out for when adding other domain user to your IIS?

  - by Jack

  I have a Windows Server 2008 R2 called Jack11 that joined a domain called Watson.org. It has IIS 7 installed. From my understanding, we need to add the following into the web.config file <system.web> <identity impersonate="true" /> </system.web> Also, we need to ensure that the server Jack11 can ping to the domain Watson.org. What other setting do we need to setup in order for a user of domain Watson.org (e.g. the user Watson\User1 to access the application in the Server IIS? This is because currently, there is a problem as follows: Exception Details: System.Data.SqlClient.SqlException: Login failed for user 'WATSON\User1'. The error message was displayed when the user User1 wish to access one of the web application in server Jack11 IIS and that web application also do some retrieval of records from the database, which is installed in SQL Server 2008 Enterprise located in the same server Jack11.

• Shrink a mounted LVM partition

  - by javanix

  I fear I already know the answer to this question, but here goes. I need to carve out a new partition on a running system. /var/ is mounted from an LVM volume (hdd1_vg-var) and has only 3% used disk space. / is mounted separately (hdd1_vg-root) and has about 80% used disk space. Filesystem Size Used Avail Use% Mounted on /dev/**/hdd1_vg-root 2.0G 1.4G 481M 75% / /dev/**/hdd1_vg-var 33G 699M 31G 3% /var Unfortunately I don't have any free extents to grow this partition organically - vgdisplay shows: Total PE 10000 Alloc PE / Size 10000 / 39.06 GB Free PE / Size 0 / 0 So seeing that I have all this free disk space on /var/, can I shrink /var/ without un-mounting it or is this just a pipe dream? I am really hoping to be able to do this work on a running system - un-mounting would of course not be difficult but it would interfere with system functionality.

Any suggestions as to what's going wrong?

• Network monitoring solution

  - by Hellfrost

  Hello Serverfault ! I have a big distributed system I need to monitor. Background: My system is comprised of two servers, concentrating and controlling the system. Each server is connected to a set of devices (some custom kind of RF controllers, doesnt matter to my question), each device connects to a network switch, and eventually all devices talk to the servers, the protocol between the servers and the devices is UDP, usually the packets are very small, but there are really a LOT of packets. the network is also somewhat complex, and is deployed on a large area physically. i'll have 150-300 of these devices, each generating up to 100+ packets per second, and several network switches, perhaps on 2 different subnets. Question I'm looking for some solution that will allow me to monitor all this mess, how many packets are sent, where, how do they move through the network, bandwidth utilization, throughput, stuff like that. what would you recommend to achieve this? BTW Playing nice with windows is a requirement.

• Windows Despooler Requires Administrator to Print

  - by Software Monkey

  Does anyone know what changes I might need to make to allow restricted users to print using a printer configured for spooling? My Windows XP SP3 system currently requires me to use an Admin account for printing if the print is configured to spool documents before printing. If the printer is configured for direct printing it works for all accounts. This used to work and some months back it just stopped, and I can't pin down why. The printer itself is configured for all uses to have complete authority. My system is locked down for restricted users given them only read authority to the entire file system except their data directories, which is how I have run my systems for years. I assume there may be a directory somewhere that I need to allow users to write to.

• How can I create an encrypted, bootable thumbdrive containing Linux?

  - by Hanno Fietz

  I want to have a bootable flash drive that's fully encrypted. I have not tested, but seem to like, TrueCrypt, which provides a fully encrypted system and has lots of other features I like (for instance, hidden volumes). Unfortunately, it seems, system encryption is only supported for Windows, although I'm not sure why. The crux here, I guess, is that you need a boot loader that is capable of asking for your password and decrypt the disk, at least the part that contains kernel and initrd. An alternative might be to have an unencrypted boot partition containing a more powerful system which will decrypt and mount the main partition. However, this brings up the question of whether you're introducing data leaks. Depending on the specific scenario, I may lack the experience to assess if this is a problem. So I'd strongly prefer a fully encrypted disk or a similarly straightforward alternative.

• Is there a successor to NTFS?

  - by hak8or

  What I am asking is if there is any file system that is known to be a possible successor of NTFS? I am asking because I just bought a new external, and realized that the path to a file, including the file name itself, cannot add up to more than 255 characters. This is known as the "Long File Name" by microsoft. I am assuming this is due to the file system limitation, so I am searching for any possible alternatives. I have a windows 7 based machine, but I am under the assumption that there would be third party software that would work with windows to make the new file system accessible by windows explorer.

• Adding HTTPS capability to WAMPSERVER 2

  - by abel

  I have WampServer 2 installed on my WinXP Pro SP3 box, Apache 2.2.11 with ssl module enabled, which runs the comnpanies intranet website. http://www.akadia.com/services/ssh_test_certificate.html gives some pointers of generating a self signed certificate. But I encounter a error while running through the example openssl genrsa -des3 -out server.key 1024 where openssl.exe is located under C:\wamp\bin\apache\Apache2.2.11\bin The error code that gets generated is 4828:error:02001015:system library:fopen:Is a directory:.\crypto\bio\bss_file.c: 126:fopen('d:/test/openssl098kvc6/openssl.cnf','rb') 4828:error:2006D002:BIO routines:BIO_new_file:system lib:.\crypto\bio\bss_file.c :131: 4828:error:0E078002:configuration file routines:DEF_LOAD:system lib:.\crypto\con f\conf_def.c:199: Where am I going wrong?

• Security of BitLocker with no PIN from WinPE?

  - by Scott Bussinger

  Say you have a computer with the system drive encrypted by BitLocker and you're not using a PIN so the computer will boot up unattended. What happens if an attacker boots the system up into the Windows Preinstallation Environment? Will they have access to the encrypted drive? Does it change if you have a TPM vs. using only a USB startup key? What I'm trying to determine is whether the TPM / USB startup key is usable without booting from the original operating system. In other words, if you're using a USB startup key and the machine is rebooted normally then the data would still be protected unless an attacker was able to log in. But what if the hacker just boots the server into a Windows Preinstallation Environment with the USB startup key plugged in? Would they then have access to the data? Or would that require the recovery key? Ideally the recovery key would be required when booted like this, but I haven't seen this documented anywhere.

• PostgreSQL 9.1 on Ubuntu Lucid fails to start - how to debug?

  - by Tom Fakes

  I'm using Vagrant with Chef Solo to setup a Lucid 64 box. I'm using a Chef recipe to install PostgreSQL 9.1 from Martin Pitt's backports. The install goes ok until the point where the database is started with /etc/init.d/postgresql start There's a log pause and the command fails. If I run pg_ctl manually, the database starts! The entire contents of my postgresql-9.1-main log file is: 2012-05-07 11:01:18 PDT LOG: database system was shut down at 2012-05-07 11:01:16 PDT 2012-05-07 11:01:18 PDT LOG: database system is ready to accept connections 2012-05-07 11:01:18 PDT LOG: autovacuum launcher started 2012-05-07 11:01:18 PDT LOG: incomplete startup packet 2012-05-07 11:01:26 PDT LOG: received fast shutdown request 2012-05-07 11:01:26 PDT LOG: aborting any active transactions 2012-05-07 11:01:26 PDT LOG: autovacuum launcher shutting down 2012-05-07 11:01:26 PDT LOG: shutting down 2012-05-07 11:01:26 PDT LOG: database system is shut down I've tried to change the postgresql config file to get more info into the logfile, but that hasn't worked at all. How do I debug this to find out what is failing so I can fix it?

• HP proliant dl360 g5 fails to reboot

  - by user1039384

  Some history of this also available here. As of my latest update on the forum linked above, now cold reboot as well as hard reset and following boot for my proliant dl360 g5 works as expected and successfully boot the system. However, soft-reboot results in internal health indicator turning RED on the front and long beeps every around 6seconds until I either cold reboot or press and hold the power button. A summary of system state when this happens: Internal Health led indicator: RED External Health led indicator: Green No led next to any component is red or amber No POST message neither on the video output nor on IML logs (verified both at the time issue occures and after cold reboot that boots the system successfully). Any thoughts please share. I hope we can knock this issue down together with your help!

• Location Services are always disabled in Mac OS X Lion

  - by rplusg

  A simple location services program was working fine on my machine and suddenly stopped working. Upon further exploring the problem, I realized that some process has disabled location services in System Preferences » Security & Privacy » Privacy. I checked Enable Location Services, but again it got disabled automatically. After some research I found that it's not just my program, even built-in system functions are also failing because of this problem for example System Preferences » Date & Time » Time Zone failed to get the current location. Every time I check Enable Location Services, I see the following error in the console logs: 16/10/12 11:23:15.636 AM [0x0-0x42042].com.apple.systempreferences: ERROR,Time,372059595.636,Function,"CLInternalSetLocationServicesEnabled",CLInternalSetLocationServicesEnabled failed 16/10/12 11:23:15.638 AM [0x0-0x42042].com.apple.systempreferences: STACK,Time,372059595.636,1 CoreLocation 0x00007fff8f9957be CLInternalSetLocationServicesEnabled + 110 Notes: WiFi is on I didn't install iOS Simulator I use Xcode Version 4.5 (4G182) I use Boot Camp and made my MacBook Pro dual boot (Mac OS X Lion and Windows 7) I do only Mac development but not iOS

• How to disable Windows File Protection in Windows XP or 7 from Registry?

  - by SEARAS

  How to disable Windows File Protection in Windows 7 and/or XP from Registry? I want to automatically replace a driver with my created driver. I used PendingFileRenameOperations key in HKLM\System\CurrentControlSet\Control\Session Manager but i've found that it can ONLY be used for simple (not-system) files, because Windows File Protection disables it for system files (see this post). Now I need to temporarily disable WFP (and turn it on after changing driver). You can tell me another way to disable it. It can help me too. Thanks in advance! Any ideas?

• where are the "ipmi sel" entries parameter descriptions?

  In order to troubleshoot a possible hardware issue I have installed ipmitools on my server and am doing queries for info related to poweron/poweroffs, hardware added/removed/status. I am trying to find some info on how to interpret sel obtained via ipmi sel list and the output looks like this : 72b4 | 10/31/2013 | 10:42:40 | System Event #0x01 | OEM System boot event | Asserted 72c8 | 10/31/2013 | 10:42:48 | System ACPI Power State #0x82 | S0/G0: working | Asserted I really want to know what "Asserted" means in this context, and also, where can I find a reference with all possible "exit status(es)" ? (Because I think that's what this is, right ?)

• Can I make my drives visible and change their partition type without losing my data?

  - by user165408

  I have made a lot of mistakes and now I cannot see my hard disk nor I can start my operating system on my laptop. All my passwords and important files on my hdd without any backup. I followed this course of action Changed my hard disk partitions to dynamic just for getting 5th partition. (1st mistake) Decreased partitions to 4 again. Backed up operating system from 4th to 3rd partition with Norton Ghost. Booted from a live CD for Windows XP. Formatted 4th partition and moved my all important data from 1st and 2nd partitions to the 4th partition. Deleted 1st and 2nd partitions and got 1 partition from half of empty space. So I have just 3 partitions and empty space between 1st and 2nd partitions. Tried to install Windows 8 to the first partition but it did not allow because it is dynamic. Also it did not allow to install to other partitions. Tried to install Windows XP to the 1st partition but it said if I continue I cannot use other drivers. Therefore I escaped from installing it. Booted from the Windows XP live CD then increased 1st partiton to less than 400mb of empty space. Therefore I thought it will be adjacent but it was shown as 2 partitions. In my computer I see just 3 drivers. Using Norton Ghost I recovered my OS to the 1st partition. (2nd mistake it was on 4th partition originally) Booted from a Windows XP live CD I tried to install bcdedit to the Windows XP live CD but it did not work. Then I tried to install EaseUS Partition Master Home Edition. It was installed with errors then I start it and it showed me an error like there is no hard disk. I looked to my PC and my drivers were not there. Booted from the Norton Ghost CD and it did not show me my drivers either, but before I was able to see them. I checked numbers of partition shown by the Norton Ghost utility and they are still have same numbers so I have to see my drivers but I cannot see them now. My hard disk is shown as extarnal dynamic now so I cannot see any drive in my PC in the live Windows XP. There are two options; first one is import extarnal disk and second one is convert disk to basic. Will they delete my data? I fear booting from CDs like Windows XP live CD, Norton Ghost CD, and the operating system CD/DVD, because they may overwrite a few MB their data to my data. These recover tools are already exist in Windows XP live CD by The Ultimate Boot CD for Windows. Can any of them help me?

• Tracking down random BSOD on windows 7

  - by pehrs

  I have gotten a computer running windows 7 handed to me that randomly, several times a day, bsods with a PAGE_FAULT_IN_NONPAGED_AREA (50) or WHEA_UNCORRECTABLE_ERROR (124). Crashes happens regardless of load. I am running out of ideas for how to track this down. Analyzing the minidumps shows the crash to be in ntkrnlmp.exe/WMIADAP.exe System has plenty of power (600w) Ram checks out fine using memtest86+ over a weekend. System is clean inside. No dust build up. Temperatures stay low. As far as I know (and reliability history shows) no new drivers were installed for several months before the problems started. All drivers are now up to date. sfc /scannow reports the system as clean. CHKDSK reports the disks as clean Removing the AV (Avast) has no effect. Any more things that should be tried on windows 7 before I start replacing the hardware?

• How to install multiple versions of the same software?

  - by Matt Love

  I manage phone systems for multiple clients. Each system uses the same administrator software, but it runs on different versions depending on what version of firmware is installed on the system controller. The software is downloaded directly from the system controller so it's the right version. For example, if the controller runs on version 5.0.2, you have to run version 5.0.2 of the administrator software. You can't administrate a 5.0.2 controller with a later versions of administrator software. Bottom line, you have to have the right version of software to log into the controller. The software is not executable on its own, you have to install it. So every time I want to log into a different controller, I have to reinstall the right software. Any way to get around this? I'm running Windows 7 Enterprise x86.
