• All commands stopped working in centos 6.5

  - by Michael

  I have made a big mistake while removing some duplicate packages as it appears to be broken. yum 1036 rpm -e --nodeps glibc-2.12-1.132.el6_5.2.x86_64 1037 rpm -e --nodeps nscd-2.12-1.132.el6_5.2.x86_64 1038 rpm -e --nodeps glibc-common-2.12-1.132.el6_5.2.x86_64 1040 rpm -e --nodeps glibc-common-2.12-1.132.el6.x86_64 glibc-devel-2.12-1.132.el6.x86_64 glibc-headers-2.12-1.132.el6.x86_64 1041 rpm -e glibc.x86_64 1042 rpm -e --nodeps glibc.x86_64 The issue happened after doing 1042 step. None of commands work(including yum, rpm, ls, cp etc) and getting error /lib64/ld-linux-x86-64.so.2: bad ELF interpreter: No such file or directory I thought that installing glibc after removing all the current ones would help to resolve the duplicate package error :( Now I realised that it is used as the C library in the GNU system and most systems with the Linux kernel. It defines the "system calls" and other basic facilities such as open, malloc, printf, exit, etc. Is there any possible solutions other than reinstall? I have lost ssh access. Maybe anything can be done using rescue cd? Thanks

• conflicting info about the running kernel version in FreeBSD

  - by John

  I asked a related question about uname before, now want to ask from another angle because the following simple yet obvious conflicting outputs may mean there is something many people did not think of (me included). I'm running FreeBSD 9 RELEASE, please see the following commands: # sysctl kern.bootfile kern.bootfile: /boot/kernel/kernel # strings /boot/kernel/kernel |grep RELEASE|grep 9 @(#)FreeBSD 9.2-RELEASE-p7 #0: Tue Jun 3 11:05:13 UTC 2014 FreeBSD 9.2-RELEASE-p7 #0: Tue Jun 3 11:05:13 UTC 2014 9.2-RELEASE-p7 The above kernel file suggests the running kernel is 9.2-RELEASE-p7. But... # dmesg Copyright (c) 1992-2012 The FreeBSD Project. Copyright (c) 1979, 1980, 1983, 1986, 1988, 1989, 1991, 1992, 1993, 1994 The Regents of the University of California. All rights reserved. FreeBSD is a registered trademark of The FreeBSD Foundation. FreeBSD 9.1-RELEASE #0 r243825: Tue Dec 4 09:23:10 UTC 2012 ... # uname -a FreeBSD localhost.localdomain 9.1-RELEASE FreeBSD 9.1-RELEASE #0 r243825: Tue Dec 4 09:23:10 UTC 2012 [email protected]:/usr/obj/usr/src/sys/GENERIC amd64 So dmesg and uname says it's 9.1-RELEASE. I also did an extensive find / -type f -exec grep -l "9.1-RELEASE" {} \; but found no possible kernel file that contains 9.1-RELEASE. What could lead to the above conflict, and what kernel I am actually running? Please note I run RELEASE and ran freebsd-update to do binary update, so no compiled kernel is involved. And I have rebooted multiple times after freebsd-update. And the system is not in jail etc, just the only system on that computer.

• Excel - "send to Mail recipient" creates 2nd copy of EMail in Inbox

  - by ssollinger

  When sending Excel sheets using the menu item "File" - "Sent To" - "Mail recipient (as attachment)" I get additional copies of the email in the Inbox. When I press "send" then I get 2 copies of the email in Outlook - as expected one in the Outbox (which moves into the Sent folder as soon it is sent off) and an additional one in the Inbox. How do I stop the copy message appearing in the Inbox? System: Excel 2000, Outlook 2000, Windows XP. Antivirus is AVG Free 2011. I know this is a very old system, but it is not my PC and there isn't any chance to get it replaced in the near future yet. SOme further details: The copy in the inbox appears at the same time as the normal copy goes into the Outbox (i.e. as soon I press send). It doesn't contain anything in the From field (i.e. there is no sender, just the recipient of the mail). It has a different icon in Outlook to the other emails - the icon is the one for "saved or unsent message". I tried it with a few different spreadsheets and it happens with all of them. It happens with every recipient, and it only happens if sending from within Excel (i.e. using the Send to menu item). I can delete the attachment before sending and it will still create a copy. If I create a new message in Outlook and then add the Excel document as attachment then I don't get the copy of the message in the inbox, it only happens when using the send to item in Excel. It only started doing this recently. Around that time the Antivirus (AVG Free) was upgraded to the latest version (from the previous version - 2010? - to version 2011), but this might not be related. I thought I know Excel really well but have never seen this happening before, and I can't find any setting in Excel or Outlook that is causing this. Any ideas?

• Solid State Drive Occasionally Freezes For A Minute While OS Is "Beach Balling"

  - by Boris_yo

  Almost a month ago I bought Intel 330 128GB solid state drive, migrated my data with Intel branded limited-feature Acronis from old HDD to new SSD, optimized with Intel Toolbox and started using it. Occassionally I get close to 1 minute freezes while seeing operating system "beach balls" and animations still work, I can interact and click on something but nothing responds, nothing loads. Recently a couple of such freezes occurred in shorter amount of time in a row. I have noticed that if I stop interacting with laptop, the freeze lasts less time than if I was interacting with laptop. But the bigger problem is when freeze just does not end and computer keeps being stuck unlil it is more than half hour and I run out of patience to keep waiting and feeling I need to restart the system because I am not getting anywhere. Such freeze happened while laptop was cold booting into Windows 7. This is when freeze hang occurred and I had to restart, only later to be greeted with Windows recovery screen stating something about faiure of boot sector and asking to insert Windows repair CD. But after I restarted, Windows booted successfully and all was well. I have filmed video of freeze hang occurring in cold boot which you can see here (on video page look below for description): http://www.youtube.com/watch?v=8b7MQlcDTUs As I have mentioned in the beginning, the SSD is less than a month old but here is S.M.A.R.T statistics just in case (TRIM is enabled btw according to CrystalDiskInfo): I want to emphasize that this SSD is the only drive I have, yet it is working in RAID mode (it was enabled initially in BIOS by previous laptop's owner) on Intel Rapid Storage drivers. I am contemplating about switching to AHCI mode but want to be sure this won't cause data loss. Additionally, the stock firmware is the only firmware available currently, yet Intel does not respond to my posts in their community board. If anyone here has this SSD model or generally has experience with SSD drives, I would love to know your thoughts.

• Mac OS Leopard: SyncServer process constantly using 100% CPU

  - by macca1

  I am running Leopard that I upgraded from Tiger. I've been noticing that every once in a while the SyncServer process starts up and eats up all the CPU. The fans will start going at full blast and the laptop will slow down to a crawl. I need to force quit the process from Activity Monitor to get it under control. It disappears for a while, but eventually gets started again. I do have an iphone as well that I sync so I'm wondering if syncServer might be an apple process checking for my phone plugged in. Edit: Tried iSync and the manual resetsync as suggested, but got this output: Vince-2:~ vince$ /System/Library/Frameworks/SyncServices.framework/Versions/A/Resources/resetsync.pl full 2010-03-12 08:03:50.230 perl[176:10b] SyncServer is unavailable: exception when connecting: connection timeout: did not receive reply PerlObjCBridge: NSException raised while sending reallyResetSyncData to NSObject object name: "ISyncServerUnavailableException" reason: "Can't connect to the sync server: NSPortTimeoutException: connection timeout: did not receive reply ((null))" userInfo: "" location: "/System/Library/Frameworks/SyncServices.framework/Versions/A/Resources/resetsync.pl line 16" ** PerlObjCBridge: dying due to NSException Vince-2:~ vince$ And during that syncServer started spinning up 95-100% just like it always does.

• How to make Synaptics touchpad work better on Linux?

  - by whitequark

  I have Debian Squeeze currently installed on a Samsung N250 netbook with a Synaptics touchpad. These touchpads are, generally, good, and everything works perfectly on Windows. The support is extremely sucky on Linux through. Of course it has all the cool features like two-finger scrolling, but the cursor (or whatever is a replacement for cursor when scrolling) is trembling awfully. It trembles when I just keep the finger on touchpad, it shakes awfully if the finger is close to the top of touchpad, and when I'm scrolling with it (no matter with two fingers or one), the page shakes a lot too. None of this behavior is observed even in Windows XP with just the default drivers installed. Here's the Xorg version: $ Xorg -version X.Org X Server 1.7.7 Release Date: 2010-05-04 X Protocol Version 11, Revision 0 Build Operating System: Linux 2.6.32-5-686 i686 Debian Current Operating System: Linux mannaz 2.6.32-5-686 #1 SMP Fri Dec 10 16:12:40 UTC 2010 i686 Kernel command line: BOOT_IMAGE=/vmlinuz-2.6.32-5-686 root=/dev/mapper/mannaz-root ro quiet splash Build Date: 02 December 2010 01:08:37AM xorg-server 2:1.7.7-10 (Julien Cristau <[email protected]>) Current version of pixman: 0.16.4 and here is synclient -l output: http://pastebin.com/Eqa6hGXP

• Best tool for monitoring backups, etc. and trending statstics from that data

  - by Randy Syring

  I have done some research on nagios, opennms, and zenoss but am not confident that I have found what I am looking for. The main driving force for me right now is being able to monitor backups. This includes mysql, mssql, and eventually some file system backups. We have a tool that wraps the backup process for these different systems and collects statistics. So, items like: number of databases backed up size of db backup file size of db backup file compressed time to make backup time to zip file I want to be able to A) have notifications if the jobs are not run according to schedule B) be able to set thresholds on the statistics which would trigger notifications C) I want to be able to trend and graph the statistics I am planning on sending this information to the monitoring application through an HTTP POST. Or, the monitoring application could pull it from a log file as well. However, we will have other processes with other "arbitrary" (from the monitoring system's perspective) statics that will want to monitor and trend, so flexibility is very important. The tool or tools should also be able to do general monitoring and trending of network interfaces, server load, etc. Once we get the backup monitoring in place, we will want to include those items as well. Thanks.

• Oracle Database Recovery Problem

• Backing up default windows installation with dd from linux running on another partition - is this fe

  - by Marek

  I am preparing to reinstall my system. I am thinking about creating a multi boot with a linux distro+Windows 7 to choose from when starting up. I would love to be able to skip all the hassle of reinstalling Windows and all programs when it starts becoming too slow in the future, thus I would like to mirror my fresh Windows system partition with some programs preinstalled. I am thinking about installing Ubuntu, making a partition for windows, installing windows with the basic environment (Visual Studio, Office, etc.) then booting into Linux and making an image of the windows partition with dd. I am not familiar with linux at all so I am a little afraid something may go wrong along the way. Is it possible to do it this way? Will I be able to partition my existing disk for multi boot easily after I install Ubuntu? Will I be able to recover the Windows partition easily using dd when I will need to re-create a fresh windows partition in the future? What other (better) approach can you recommend to achieve the goal of easy disk mirroring (for free)?

• Solaris 10: How to image a machine?

  - by nonot1

  I've got a Solaris 10 workstation that I'd like to create a full image backup from. The machine has 2 drives, one UFS for system root, and 1 ZFS for data storage. I intend to add a third HD to keep the backup images of both primary drives (including any zfs snapshots). The purpose is not disaster recovery, but rather to allow me to easily blow away a series of application installation/configuration changes I intend to try. What's the best way to do this? I'm not too familiar with Solaris, but have some basic Linux knowledge. I looked at CloneZilla, but it does not support Solaris. I'm OK with just a dd | gzip > image style solution, but I'd need some way to first zero-out the non-used blocks on the primary drives to aid gzip. They are are much larger than my 3rd drive, but hardly have any real data. Update to clarify: I specifically want to avoid using any file-system snapshot functionality, because part of the app configuration changes involve/depend slightly on existing and new snapshots. Ideally the full collection of snapshots should be part of the backup. Virtualization not an option, because the goal is to do performance evaluation on a very specific HW configuration. For the same reason, the spurious "back up" snapshots could skew performance data. Thank you

• Windows 7 boot problem on a Lenovo Thinkpad Z61m 9450HAG

  - by Matt Taylor

  I recently did a full upgrade of Windows 7 on my Thinkpad. Everything worked fine after up until the second reboot (the first reboot after some updates installed worked OK). At second reboot time the system would just black screen before the Windows logo appears. Disk/wireless/power/battery lights are all lit and the disk light is active (flickering). However, if I remove my battery and boot with just power it boots fine and quickly, and everything is OK. Any help on why this won't boot with battery plugged in is greatly appreciated. I need to take this battery out on the road/trains, etc. A little more detail on this story. The battery I had inserted when doing the (failed) boot was a long life battery. I have not tried inserting this battery when Windows is logged in. I have another (normal life) battery that I have charged up within Windows. It has just got to 100% and I am about to reboot with it in. I am using the Lenovo power manager to diagnose the battery - all seems OK. I will report back shortly as to the outcome. OK, so I chose the reboot option from within Windows, the machine seemed to shutdown okay, but then stalled. It didn't turn off completely and didn't reboot, but just sat, with the fan humming, somewhere in between! I had to hold the power button in for a few seconds until the fan stopped and then hit the power button again to boot the machine from fresh. One good thing, with this battery (the normal one) it booted into Windows 7 the first time with a battery! So, now I have rebooting issues. I have 3 errors in the event log: A timeout was reached (30000 milliseconds) while waiting for the lxdxCATSCustConnectService service to connect. The lxdxCATSCustConnectService service failed to start due to the following error: The service did not respond to the start or control request in a timely fashion. The following boot-start or system-start driver(s) failed to load: cdrom Any thoughts?

• Why does hiberfil.sys come back from the dead on Windows 7?

  - by Corey White

  I have Windows 7 running on a small (40GB) partition, with 4GB ram. This means that the hiberfil.sys file created by Hibernate takes up a significant portion of the available diskspace. I would like to remove it. I am aware that I can disable Hibernate and remove hiberfil.sys by entering powercfg -h off in an elevated command prompt. This works -- the file is immediately removed, and after doing so, the HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Power\HibernateEnabled key is (correctly) set to 0. However, the next time I reboot the PC, hiberfil.sys returns from the dead, Hibernate is reenabled, and that registry key has returned to 1. I'm pretty much at my wits' end with this. Almost everything I can find online related to removing the hiberfil.sys file simply suggests using powercfg to turn off hibernation, and that appears to work for just about everyone. But it just keeps coming back for me! (Like a vampire, sucking up my disk space.) I did find one other thread from someone who seems to have had the same issue, but none of the suggestions there worked for the original poster (or for me). Still, I have tried everything listed there, including: Disabling hybrid sleep Disabling Hibernate through the command prompt, through the Power Options GUI, and through both (in both orders) Manually changing the HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Power\HibernateEnabled key Pretty much everything else I can think of! I do want to reiterate that I have no problem removing the file -- that works great. It just comes back after every reboot. I'm about ready to throw in the towel and just run a script on login to disable Hibernate each time, even though that seems like a crazily hacky "solution" . . . but I was hoping someone here could suggest something else, first. Thanks!

• Parsing T-SQL – The easy way

  - by Dave Ballantyne

  Every once in a while, I hit an issue that would require me to interrogate/parse some T-SQL code.  Normally, I would shy away from this and attempt to solve the problem in some other way.  I have written parsers before in the the past using LEX and YACC, and as much fun and awesomeness that path is,  I couldnt justify the time it would take. However, this week I have been faced with just such an issue and at the back of my mind I can remember reading through the SQLServer 2012 feature pack and seeing something called “Microsoft SQL Server 2012 Transact-SQL Language Service “.  This is described there as : “The SQL Server Transact-SQL Language Service is a component based on the .NET Framework which provides parsing validation and IntelliSense services for Transact-SQL for SQL Server 2012, SQL Server 2008 R2, and SQL Server 2008. “ Sounds just what I was after.  Documentation is very scant on this so dont take what follows as best practice or best use, just a practice and a use. Knowing what I was sort of looking for something, I found the relevant assembly in the gac which is the simply named ,’Microsoft.SqlServer.Management.SqlParser’. Even knowing that you wont find much in terms of documentation if you do a web-search, but you will find the MSDN documentation that list the members and methods etc… The “scanner”  class sounded the most appropriate for my needs as that is described as “Scans Transact-SQL searching for individual units of code or tokens.”. After a bit of poking, around the code i ended up with was something like [System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.Management.SqlParser") | Out-Null $ParseOptions = New-Object Microsoft.SqlServer.Management.SqlParser.Parser.ParseOptions $ParseOptions.BatchSeparator = 'GO' $Parser = new-object Microsoft.SqlServer.Management.SqlParser.Parser.Scanner($ParseOptions) $Sql = "Create Procedure MyProc as Select top(10) * from dbo.Table" $Parser.SetSource($Sql,0) $Token=[Microsoft.SqlServer.Management.SqlParser.Parser.Tokens]::TOKEN_SET $Start =0 $End = 0 $State =0 $IsEndOfBatch = $false $IsMatched = $false $IsExecAutoParamHelp = $false while(($Token = $Parser.GetNext([ref]$State ,[ref]$Start, [ref]$End, [ref]$IsMatched, [ref]$IsExecAutoParamHelp ))-ne [Microsoft.SqlServer.Management.SqlParser.Parser.Tokens]::EOF) { try{ ($TokenPrs =[Microsoft.SqlServer.Management.SqlParser.Parser.Tokens]$Token) | Out-Null $TokenPrs $Sql.Substring($Start,($end-$Start)+1) }catch{ $TokenPrs = $null } } As you can see , the $Sql variable holds the sql to be parsed , that is pushed into the $Parser object using SetSource,  and then we will use GetNext until the EOF token is returned.  GetNext will also return the Start and End character positions within the source string of the parsed text. This script’s output is : TOKEN_CREATE Create TOKEN_PROCEDURE Procedure TOKEN_ID MyProc TOKEN_AS as TOKEN_SELECT Select TOKEN_TOP top TOKEN_INTEGER 10 TOKEN_FROM from TOKEN_ID dbo TOKEN_TABLE Table note that the ‘(‘, ‘)’  and ‘*’ characters have returned a token type that is not present in the Microsoft.SqlServer.Management.SqlParser.Parser.Tokens Enum that has caused an error which has been caught in the catch block.  Fun, Fun ,Fun , Simple T-SQL Parsing.  Hope this helps someone in the same position,  let me know how you get on.

• Dell Dimension 8400 Startup error

  - by Michael

  Hello all, thanks first for taking the time to read this and possibly help me...... now I am pretty decent of a computer tech...but not enough. I am having an issue with my computer which is running windows xp and as I mentioned it is a dell Dimension 8400. as soon as I power the system up the fan goes into hyper drive (spins like crazy and is very loud) then the start up screen with dell comes up and the loading bar gets stuck on the process of "Bios Revision A00" and never loads beyound that. I have read alot about it and think that the main problem was that it can not locate the file (which does have an updated version) I think it is A09. I can not enter safe mode, Bios mode or anything. I do have the file on my other computer and I was wondering if there is a way that I can use a usb flash drive (as I have read on other sites) to create a bootable MS-Dos diskette but I am failing at creating as such....is this possible? or is there anything else I can do? I tried to remove the battery from the system for about 10 minutes while it was completely unplug and tried then to reboot it and go into the bios menu but the same thing keeps happening....can anyone help me :-(

I have run "sfc", no problems. There are no Device Errors in Device Manager. I have also run "vssadmin list writers", no problems. Whats going on??? Would it be a good idea to re-install Windows 7?

• Overriding HOMEDRIVE and HOMEPATH as a Windows 7 user

  - by MikeC

  My employer has an Active Directory group policy which sets my Windows 7 laptop HOMEDRIVE to "M:" (a mapped network drive) and my HOMEPATH to "\". Since I have read-only permissions for the root of that shared drive, I cannot create files or directories in my windows home directory. My attempts to work with the IT department have been unsuccessful. Is there a way for me to globally change these envars at boot or login time? I need for all applications to use alternate values (such as "C:" and "\Users\myname"). I have some installed utilities (like gvim and others) that store preference files in the user's home directory. IMPORTANT: Changing these envars under "System Properties Environment Variables" does not work. I have tried setting these as both User and System Variables (including a reboot). TypingSET HOMEin a DOS window clearly shows that my settings are ignored. Also, using "Start in" in a Windows shortcut will also not solve this, as I need things like Explorer context menu items (like "Edit with Vim") to operate correctly. I do have admin rights on this company laptop, but I am not a Win7 guru. Back in the day, a boot script would have solved this in a minute. Is it even possible today? Thanks.

  Hi, I have an ISO file of the Windows 7 DVD and I want to install it on my PC which currently only runs Linux. I don't have any DVD drive. I have some unpartitioned space on one disk where I want to install it in. When I am doing this for Linux, I usually just create the partitions from the running system, format them, mount them, copy files over, chroot into it, setup the stuff and I can boot into it (or I use some of the uncountable available scripts which do exactly that automatically). However, I have no idea how to do the same thing with Windows. So far, I tried with VMware, i.e. I gave it direct full access to the disk where I want to install it in, installed it there, then tried to boot natively into it. The Windows logo showed up but after maybe 3 seconds or so, it crashes. Safe mode also crashes. I already expected that this probably would exactly behave the way it does right now because I have heard that Windows is quite sensible about hardware changes (i.e. the VMware hardware and the real hardware). However, how can I fix it now that it works? Or I could also just delete it again and try just over. But how exactly? I also searched for ways to boot directly into an ISO file. There seem to be ways to do that via GRUB (and maybe some additional boot loader), although quite complicated. I already tried one method (GRUB: map ...iso (hdX)), however, that didn't worked. Also, even if it does work, I will get into trouble when I boot into the newly installed Windows and it requests for the DVD (because it does that at the first boot into the new system). Seems all quite complicated. Isn't there some easy way like I would do it for Linux? Or what would be the easiest way to get what I want?

• What's next for all of these Microsoft "overlapping" and "enhanced" products ?

  - by indyvoyage

  Recently I attended a road show, organised by MS Gold Partner company in the UK. The products discussed were: SharePoint server (2010 and 2007), Exchange server, Office Communication Server 2007, Exchange hosted services Office Live meeting, Office Communicator, System Center Configuration Manager and Operation Manager, VMware, Windows 7 etc. As Microsoft claims the enhancement in the each product against higher version, I felt that clients are not much interested in all these details. For example Office Communicator, surely they have improved a lot the product and first site all said 'WOW' great product, but nobody wish to pay money for all these extra features. Some argued, they are bogged down by all these increased number of menus. They don't need soft call feature included with mobile call. It apply for all other products as well such as MS office (next what 2 ribbons ?), windows OS and many more. Indeed there must be good features in all these products, but is it worth to spend money and time to update the older system ? Also sometimes these feature will decrease the productivity instead increase it. *So do you think what ever enhancement MS is doing in the products is only for selling purpose, not a real use ?? and I think also keep the developer busy learning the new tools and features. * I am sure some some people here will argue that some people need this sort of features. But I am not talking about NASA or MI5 guys. I am talking of usual businesses and joe public. Any ideas welcome.

• SNMP Access on Ubuntu

  I am trying to use SNMP to monitor a machine locally on its self and remotely. This is the snmpd.conf (Ubuntu 8.04.1): # sec.name source comunity com2sec readonly 1.2.3.4 nicenandtight com2sec readonly 5.6.7.8 reallysafe group MyROGroup v1 readonly group MyROGroup v2c readonly group MyROGroup usm readonly view all included .1 view system included .iso.org.dod.internet.mgmt.mib-2.system access MyROGroup "" any noauth exact all none none syslocation my house syscontact me <[email protected]> exec .1.3.6.1.4.1.2021.7890.1 distro /usr/bin/distro smuxpeer .1.3.6.1.4.1.674.10892.1 includeAllDisks 95% 1.2.3.4 is the local machines IP and everything is working locally. 5.6.7.8 is the remote machine and initially I am just trying to touch SNMPD with snmpwalk from the remote machine; snmpwalk -v 2c -c reallysafe 1.2.3.4 Timeout: No Response from 1.2.3.4 I have added to iptables as the very first rule; -A INPUT -p udp -m udp --dport 161 -j ACCEPT With such a loose iptables rule I can't see why I can't even touch the SNMPD on that Uubuntu Machine. There are more specific rules further down the table but as I couldn't connect I added the above. TCPDump shows the UDP packets coming in. What could be going wrong here?

• Manipulating IIS7 Configuration with Powershell

  - by John Price

  I'm trying to script some IIS7 setup tasks in PowerShell using the WebAdministration module. I'm good with setting simple properties, but am having some trouble when it comes to dealing with collections of elements in the config files. As an immediate, example, I want to have application pools recycle on a given schedule, and the schedule is a collection of times. When I set this up via the IIS management console, the relevant config section looks like this: <add name="CVSupportAppPool"> <recycling> <periodicRestart memory="1024" time="00:00:00"> <schedule> <clear /> <add value="03:31:00" /> </schedule> </periodicRestart> </recycling> </add> In my script I would like to be able to accomplish the same thing, and I have the following two lines: #clear any pre-existing schedule Clear-WebConfiguration "/system.applicationHost/applicationPools/add[@name='$($appPool.Name)']/recycling/periodicRestart/schedule" #add the new schedule Add-WebConfiguration "/system.applicationHost/applicationPools/add[@name='$($appPool.Name)']/recycling/periodicRestart/schedule" -value (New-TimeSpan -h 3 -m 31) That does almost the same thing, but the resulting XML lacks the <clear/> element that is created with via the GUI, which I believe is necessary to avoid inheriting any default values. This sort of collection (with "add", "remove", and "clear" elements) seems to be fairly standard in the config files, but I can't seem to find any good documentation on how to interact with them consistently.

• compile ntp without ssl

  - by Zulakis

  I need to deploy ntp to a very space-critical pxe-imaging-system. (Yes, each KB matters.) Footprint needs to be as small as possible, so I want to compile ntp without linking openssl. According to the manual this is should be possible: If available, the OpenSSL library from http://www.openssl.org is used to support public key cryptography. The library must be built and installed prior to building NTP. The procedures for doing that are included in the OpenSSL documentation. The library is found during the normal NTP configure phase and the interface routines compiled automatically. Only the libcrypto.a library file and openssl header files are needed. If the library is not available or disabled, this step is not required. I already tried out ./configure --without-openssl however, this didn't help. This is my ldd output: ldd ntpd/ntpd linux-gate.so.1 => (0xb7706000) libm.so.6 => /lib/i686/cmov/libm.so.6 (0xb76d5000) libcrypto.so.0.9.8 => /usr/lib/i686/cmov/libcrypto.so.0.9.8 (0xb7582000) librt.so.1 => /lib/i686/cmov/librt.so.1 (0xb7578000) libc.so.6 => /lib/i686/cmov/libc.so.6 (0xb741d000) /lib/ld-linux.so.2 (0xb7707000) libdl.so.2 => /lib/i686/cmov/libdl.so.2 (0xb7419000) libz.so.1 => /usr/lib/libz.so.1 (0xb7404000) libpthread.so.0 => /lib/i686/cmov/libpthread.so.0 (0xb73eb000) The system I am compiling on is 32-bit debian lenny using openssl 0.9.8g-15+lenny16. What is the correct configure option to compile ntp without openssl?

• Creating a pseudoterminal to make sudo happy

  - by larsks

  I need to automate the provisioning of a cloud instance (running Fedora 17) for which the following initial facts are true: I have ssh-key based access to a remote user (cloud) That user has password-free root access via sudo. Manual configuration is as simple as logging in and running sudo su - and having at it, but I would like to fully automate this process. The trick is that the system defaults to having the requiretty option enabled for sudo, which means that an attempt to do something like this: ssh remotehost sudo yum -y install puppet Will fail: sudo: sorry, you must have a tty to run sudo I am working around this right now by first pushing over a small Python script that will run a command on a pseudoterminal: import os import sys import errno import subprocess pid, master_fd = os.forkpty() if pid == 0: # child process: now that we're attached to a # pty, run the given command. os.execvp(sys.argv[1], sys.argv[1:]) else: while True: try: data = os.read(master_fd, 1024) except OSError, detail: if detail.errno == errno.EIO: break if not data: break sys.stdout.write(data) os.wait() Assuming that this is named pty, I can then run: ssh remotehost ./pty sudo yum -y install puppet This works fine, but I'm wondering if there are solutions already available that I haven't considered. I would normally think about expect, but it's not installed by default on this system. screen can do this in a pinch, but the best I came up with was: screen -dmS sudo somecommand ...which does work but eats the output. Are there any other tools available that will allocate a pseudoterminal for me that are going to be generally available?

• So who decided VGA cables should be symetrical ? [closed]

  - by mgb

  < rant So who decided that VGA cables should be the same gender connector at both ends? I just spent an hour trying to fix a server that would apparently boot but wouldn't display any post messages - I needed to change some bios settings. The monitor gives me a helpful error message - "unable to display this resolution". Wondering how it can't show simple VGA res, I reset the bios, when that doesn't work I remove the BIOS battery. The system is in a rack with a keyboard and monitor mounted 6ft away - with the cable running through the normal waist thick rats nest of wiring of wiring. The monitor worked with another system, so it and the VGA cable are good, I brought in another monitor and tried that - still nothing. Eventually I ripped the rack apart to discover that the other end of the VGA connector I was trying to plug into the server was actually plugged into another server box ! And the second monitor I was testing was plugged into the first monitor. An error message like - "I'm actualy plugged into another monitor stupid" - would be useful. So would having a connector with a male end and a female end. < end rant - thank you

• How can I switch from a custom linux network namespace back to the default one?

  - by Martin

  With ip netns exec you can execute a command in a custom network namespace - but is there also a way to execute a command in the default namespace? For example, after executing these two commands: sudo ip netns add test_ns sudo ip netns exec test_ns bash How can the newly created bash execute programs in the default network namespace? There is no ip netns exec default or anything similar as far as I've found. My scenario is: I want to run a SSH server in a separate network namespace (to keep the rest of the system unaware of the network connection, as the system is used for network testing), but want to be able to execute programs in the default network namespace via the SSH connection. What I've found out so far: Created network namespaces are listed as files under /var/run/netns (but there is no file for the default namespace) The ip netns exec code can be found here: http://git.kernel.org/cgit/linux/kernel/git/shemminger/iproute2.git/tree/ip/ipnetns.c#n132 - I haven't grasped everything that it is doing yet, but it doesn't look very promising. ip netns identify $$ as suggested by Howto query and change network namespace on linux? returns nothing when in the default network namespace
