• How do I log back into a Windows Server 2003 guest OS after Hyper-V integration services installs and breaks my domain logins?

  - by Warren P

  After installing Hyper-V integration services, I appear to have a problem with logging in to my Windows Server 2003 virtual machine. Incorrect passwords and logins give the usual error message, but a correct login/password gives me this message: Windows cannot connect to the domain, either because the domain controller is down or otherwise unavailable, or because your computer account was not found. Please try again later. If this message continues to appear, contact your system administrator for assistance. Nothing pleases me more than Microsoft telling me (the ersatz system administrator) to contact my system administrator for help, when I suspect that I'm hooped. The virtual machine has a valid network connection, and has decided to invalidate all my previous logins on this account, so I can't log in and remotely fix anything, and I can't remotely connect to it from outside either. This appears to be a catch 22. Unfortunately I don't know any non-domain local logins for this virtual machine, so I suspect I am basically hooped, or that I need ophcrack. is there any alternative to ophcrack? Second and related question; I used Disk2VHD to do the conversion, and I could log in fine several times, until after the Hyper-V integration services were installed, then suddenly this happens and I can't log in now - was there something I did wrong? I can't get networking working inside the VM BEFORE I install integration services, and at the very moment that integration services is being installed, I'm getting locked out like this. I probably should always know the local login of any machine I'm upgrading so I don't get stuck like this in the future.... great. Now I am reminded again of this.

• Looking for ballpark pricing on an affordable a Cisco VOIP solution for our office

  - by guytech

  We have about 8 incoming PSTN lines that are currently on an old and antiquated Nortel Meridian ICS system. This system has been giving us some grief. We're looking for a new VOIP solution. I've been looking at a Cisco solution and it does seem pricey but I'm sure effective. Unfortunately, we probably can't afford a Cisco Unified Communications 520 which seems to be the ideal solution. We have about 15 people who need an extension and voicemail. We really don't have any need for a fancy system just an auto attendant of some sort when people call us. It looks like we'll have to get an older router and an addon card for what we're looking for to get best value pricing. However, I don't know a a lot about Cisco voice products so I'm a bit lost as to what to get. The only thing I am sure on is the pricing on VOIP phones which we expect to be about ~$100-200. However, I'm not sure what pieces of VOIP infrastructure to get. Any advice? I am familiar with Asterisk but right now I'm looking on pricing concerning a Cisco solution.

• windows 7 turns off itself everyday at about 9am

  - by Radek

  I was given this comp at work and after a week or so this strange thing started to happen in the middle of doing something :-( It turns off itself at about 9.10am every morning Just once a day and it works fine after it had it little nap. it happens both if the comp was on all night or I turned it off before leaving the office. I tried to swapped the memory as I was told that there was an issue with memory. But moving or removing any memory did not make any difference. I am not aware that I would install any program that could cause that. I installed AVG and set it up to do every day scan about 8am + if restart is needed it requires user confirmation. 'The Software Protection service has stopped' few minutes before it turned off itself but it happened also at other times without the computer turned off. I turned off Windows automatic updates as the first thing when I got the comp configuration Windows 7 Ultimate Intel Core2 Quad Q9550 at 2.8GH, 8GB RAM ST31000528AS Barracuda 7200.12 SATA 3Gb/s 1TB Update Below message are logged when I turn the comp on again. Message 1: The previous system shutdown at 9:08:54 AM on ?6/?29/?2010 was unexpected. Message 2: Level:Critical Source: Kernel Power EventID 41 Task Category (63) The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly. Log after manual restart Update 2 (task scheduler)

• TEMP environment variable occasionally set incorrectly

  - by Roger Lipscombe

  Occasionally, I find my TEMP and TMP environment variables set to C:\Windows\TEMP. They should be set to %USERPROFILE%\AppData\Local\Temp, and are configured correctly in System Properties. This manifests itself as error messages like the following: ---> System.InvalidOperationException: Unable to generate a temporary class (result=1). error CS2001: Source file 'C:\Windows\TEMP\gb_pz65v.0.cs' could not be found error CS2008: No inputs specified ...which occurs in various .NET applications (in particular Visual Studio 2010 or SQL Server Management Studio). Alternatively, SQL Server Management Studio will report: Value cannot be null. Parameter name: viewInfo (Microsoft.SqlServer.Management.SqlStudio.Explorer) If I run PowerShell elevated, then $env:TEMP is set correctly. If I run PowerShell non-elevated, then it's not. I believe that it should be set correctly in both cases. If not, it's the wrong way round. The same is true for CMD.EXE. Rebooting fixes it, temporarily, until something breaks it again. Presumably something loaded into Explorer.exe is messing with its environment variables, but what? The values in the registry are correct, even while this is happening: HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment has TEMP = %SYSTEMROOT%\Temp HKCU\Environment has TEMP = %USERPROFILE%\AppData\Local\Temp By setting a breakpoint on shell32!RegenerateUserEnvironment, I'm able to trap it when it happens, but I still don't know why explorer.exe is reading the wrong environment variables. I can reproduce it consistently by broadcasting a WM_SETTINGCHANGE message (I wrote a one-line C++ program to do this). Watching the activity in Process Monitor shows that explorer.exe doesn't even look at HKCU\Environment. What is going on?

• How to migrate WinXP from failing old HD to new one

  - by Péter Török

  Following this issue, we have all our important data backed up now. I also bought and installed a new replacement hard disk (WD 160GB PATA) as secondary (slave) drive. I created two primary NTFS partitions on it: a 40 GB system partition, and a 110GB data partition. In theory I could start reinstalling WinXP from scratch on the new system partition, then copying over all user data from the old drive to the new data partition. Once this is done, I could even throw away the old drive, or keep it just to see what happens. (Note: I don't want to clone the whole drive as it contains a dual boot setup with an old Linux installation which I don't need anymore, and anyway, a fresh reinstall would do WinXP good to get rid of many years' clutter.) However, I am lazy :-) The old HD is still functioning, the problem has not manifested again since. So I feel there is no need to hurry with a complete OS reinstall. What I don't know though is whether I will be able to install WinXP on the new system partition at a later stage without affecting the contents of the data partition on the same drive. If this is possible, I can just move over all our data to the new data partition to have it safe, then continue running WinXP from the old drive as long as it works. Does anyone see any problems/risks with this plan?

• Disable or remove filter driver for single HID device

  - by snoopen

  Running Windows XP in a corporate setting here. I have an issue where a filter driver is interfering with the functionality of different USB HIDs. For example graphics tablets do not respond while the filter driver is in place. I've also had the issue with foot pedals used with transcription software. My question is really two fold: A) what makes Windows use a filter driver on one HID but not another? B) when a filter driver is causing conflicts how can I disable it on the affected devices? Background I've previously narrowed down the issue to the filter driver by uninstalling the software (Funk Proxy Host) responsible for the filter driver. The software is a type of RDP we use here at work. (I might have even booted into safe mode and renamed the file, I forget). I believe the filter driver is present to disable or modify the use of the local keyboard and mouse while admin staff are assisting users. Either way I don't have the authority to just go uninstalling this software. As far as I can tell the software versions are the same, however I'm not sure if the device driver definitions are all the same as I don't know where these things would be located. To check for the presence of the filter driver I locate the hardware device in Device Manager, click Properties Driver tab Driver Details.... It shows up as ph32ihid.sys. Even though all machines are meant to have the same SOE and do have Funk Proxy Host installed I don't always have issues with the same HIDs. A few machines here the foot pedals without any issues. I've not had any machines work with the graphics tablet without uninstalling Funk software. Driver details I've just read up a bit more about filter drivers and found the drivers description in the registry under "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ProxyHostHIDFilter" There it's called "Kernel-mode HID filter driver for the Proxy Host". Presumably I could also disable it here but that would be system wide which is probably not desirable?

• Windows Server 2008 - RAID 5 Fails on Reboot

  - by Adam

  Hey, I've got an install of Windows Server 2008 Enterprise. It's running software RAID-5 with five disks. The disks were originally formatted under Windows Server 2003, but came up fine once I installed Windows Server 2008. The issue I'm having is that every time I reboot the server, the RAID comes up with a "Failed Redundancy" - the data stays available. I have 4 disks on a PCI SATA controller, and one of the disks connected to the motherboard's on-board SATA ports. (The other on-board port has the system disk connected.) I was having Disk #4 fail consistently, so I tried swapping the cables on the controller end. I swapped the on-board RAID disk with one on the PCI controller. Same issue now, expect with disk #1. Once the system's up, I can reactivate the RAID, it will resync for a while, then go to "Healthy", and will stay that way for an indefinite amount of time - until I reboot. As soon as I reboot, the disk drops again. I've ruled out disk + cable with the recabling. I don't believe it would be the controller as it seems to work fine most of the time - only failing on reboot, and the other port on the same controller connects the system disk - which is clearly working. I did look in the event log, but didn't see anything particularly relevant (although I didn't know what I was looking for - just looked for anything with a "Warning" or "Error" symbol that looked disk-related :)). I'm not particularly familiar with RAID on Windows, does anyone have any idea why this might be doing this? Any idea how to fix it? Any suggestions appreciated! -- Adam

• Ubuntu in failed state after upgrade from 10.04 to 10.10 - How to recover?

  - by Harvey

  I was running Ubuntu 10.04 and attempted to upgrade to 10.10. I have a really slow connection (DSL 128kbits/sec) and copying the upgrade files took about 26 hours. I of course let it run unattended. When I came back, I notice the following 3 dlgs: 1. Could not install the upgrades The upgrade has aborted. Your system could be in an unusable state. A recovery will run now (dpkg -- configure -a). 2. gpk-update-icon Distribution upgrades available maverick 10.10 (stable) [more information] [Do no show this again] [Cancel] [Ok] 3. gpk-update-icon Security updates available The following important updates are available for your computer: libwebkit-1.0-2-dbg - Web content engine library for Gtk+ - Debugging symbols libcupsimage2 - Common UNIX Printing System(tm) - Raster image library ... What is the best response to all of this? I went through something similar in an attempted network upgrade from 8.04 to 10.04 and had to reload the unbootable machine fresh from distribution media (all data was lost). I'd like to avoid that here. I have not yet responded to the dialogs, and want to make sure the system is still bootable and not lose my data this time.

• User not in the sudoers file. This incident will be reported

  - by Sergiy Byelozyorov

  I need to install a package. For that I need root access. However the system says that I am not in sudoers file. When trying to edit one, it complains alike! How I am supposed to add myself to the sudoers file if I don't have the right to edit one? I have installed this system and only administrator. What can I do? Edit: I have tried visudo already. It requires me to be in sudoers in the first place. amarzaya@linux-debian-gnu:/$ sudo /usr/sbin/visudo We trust you have received the usual lecture from the local System Administrator. It usually boils down to these three things: #1) Respect the privacy of others. #2) Think before you type. #3) With great power comes great responsibility. [sudo] password for amarzaya: amarzaya is not in the sudoers file. This incident will be reported. amarzaya@linux-debian-gnu:/$

• High memory utilization with firebird + windows server 2008 r2

  - by chesterman

  i have a Windows Server 2008 R2 (64bit) running a 64bit installation of Firebird 2.1.4.18393_0 in a 4GB phisical server. After a while, the task manager show that all memory is used, but the sum of the memory of all process does not stack to the half of the memory. Unfortunally, it's start swapping. Using RAMMAP, i can see that my entire database file is mapped into the memory. This only occours in windows server 2008 r2 and windows 7 64 bit. i can use firebird 32 or 64bit installations, doesn't matter. How can i prevent this? Why this only occours in w2k8r2 and w7? tks in advance ** UPDATE Aparently, this occours by the use of all memory by the file system cache. The microsoft documentations explain that this WAS a issue in windows xp, 2k3, vista and 2k8, but it was solved in 7 and 2k8r2. also adds that this issue is more common in 64bit hosts. (http://support.microsoft.com/kb/976618) there are some tools (DynCache, setcache and the Get/SetSystemFileCacheSize system calls from windows API) that allows me to fix a upper limit to the memory usage by the fscache, but the documentation argues that i should not do this in w2k8r2 because it will severely impact on the overall system performance. anyway, i tried, the performance remained the same shit and the use of the page file remained, although there is now more the 1gb of free memory.

• Changing the default boot option without losing the boot menu

  - by hvd

  I've had a working multi-boot setup with the Windows boot loader, containing menu items for two Windows 7 systems, and one for Grub. Grub in turn contains multiple menu items, but I think that's not relevant here. I've upgraded one system to Windows 8. When I now set a different system as the default, I lose the boot menu, and I lose the possibility of booting into the other systems. I've set Windows 7 as the default, rebooted, and get Windows 7, but I don't get to choose which system to boot into. I can run its own bcdedit to change the default back to Windows 8, and another reboot shows the boot menu again, but how can I avoid defaulting to Windows 8? Here are my current boot settings, is there anything that is misconfigured? C:\WINDOWS\system32>bcdedit Windows Boot Manager -------------------- identifier {bootmgr} device partition=F: description Windows Boot Manager locale nl-NL inherit {globalsettings} integrityservices Enable default {current} resumeobject {2f8b77f0-a30b-11e1-a9c6-a4bd8d37f662} displayorder {current} {2f8b77e3-a30b-11e1-a9c6-a4bd8d37f662} {2f8b77ee-a30b-11e1-a9c6-a4bd8d37f662} toolsdisplayorder {memdiag} timeout 30 Windows Boot Loader ------------------- identifier {current} device partition=C: path \WINDOWS\system32\winload.exe description Windows 8 locale nl-NL inherit {bootloadersettings} integrityservices Enable recoveryenabled No allowedinmemorysettings 0x15000075 osdevice partition=C: systemroot \WINDOWS resumeobject {2f8b77f0-a30b-11e1-a9c6-a4bd8d37f662} nx OptIn bootmenupolicy Standard Windows Boot Loader ------------------- identifier {2f8b77e3-a30b-11e1-a9c6-a4bd8d37f662} device partition=D: path \Windows\system32\winload.exe description Windows 7 locale nl-NL osdevice partition=D: systemroot \Windows resumeobject {59616f59-a2ba-11e1-b73a-806e6f6e6963} nx OptIn pae Default bootmenupolicy Standard hypervisorlaunchtype Auto detecthal Yes sos No debug No Real-mode Boot Sector --------------------- identifier {2f8b77ee-a30b-11e1-a9c6-a4bd8d37f662} device partition=C: path \grub\winloader\grub.boot description Grub 2

• Master File Table Corrupt, any way to save data?

  - by domen

  hi. I've used search, but none of the results match my problem so I didn't have to ask separate question. I've Installed Windows 7 RTM recently and since then partitions located on one of my HDDs have gone "crazy". They used to "freeze" and didn't open in explorer for some time (minute or two, usually), sometimes all partitions of the drive wouldn't show until reboot and finally, one of those partitions started showing "disk structure is corrupted and unreadable" warning, it appeared in Disk Management window as RAW and chkdsk showed "mft corrupt". There were no important data on the partition and I didn't have enough time to analyze the problem at the moment, so I just reformatted it and ran antivirus scan on system. After that problem settled for some time, but yesterday the problematic HDD vanished again from the system. After reboot chkdsk identified mft of four partitions corrupt and now they are all in same conditions as the above mentioned one. But the difference is that the files stored in them are extremely important. and just for info: I upgraded from Win7 build 7077, but had some performance issues, so I reformatted system drive and installed fresh Win7 RTM on it. I've downloaded TestDisk and it shows all the partitions marked as NTFS (not RAW) and my knowledge of the program wasn't sufficient to obtain any other info from it :-) and the images that could help describe the problem (sorry, I'm not allowed to post images and more than one hyperlink): http:// img22.imageshack.us/img22/5909/chkdskz.jpg http:// img198.imageshack.us/img198/5576/computeray.jpg I'm interested, is there a way to let me restore the MFT or just access files so I can backup them before reformatting the drive. Thanks for your time. :) P.S. my reformatted drive is showing no problems, could there be a problem with windows 7 itself? I googled, but with no results.

• Distributed storage and computing

  - by Tim van Elteren

  Dear Serverfault community, After researching a number of distributed file systems for deployment in a production environment with the main purpose of performing both batch and real-time distributed computing I've identified the following list as potential candidates, mainly on maturity, license and support: Ceph Lustre GlusterFS HDFS FhGFS MooseFS XtreemFS The key properties that our system should exhibit: an open source, liberally licensed, yet production ready, e.g. a mature, reliable, community and commercially supported solution; ability to run on commodity hardware, preferably be designed for it; provide high availability of the data with the most focus on reads; high scalability, so operation over multiple data centres, possibly on a global scale; removal of single points of failure with the use of replication and distribution of (meta-)data, e.g. provide fault-tolerance. The sensitivity points that were identified, and resulted in the following questions, are: transparency to the processing layer / application with respect to data locality, e.g. know where data is physically located on a server level, mainly for resource allocation and fast processing, high performance, how can this be accomplished? Do you from experience know what solutions provide this transparency and to what extent? posix compliance, or conformance, is mentioned on the wiki pages of most of the above listed solutions. The question here mainly is, how relevant is support for the posix standard? Hadoop for example isn't posix compliant by design, what are the pro's and con's? what about the difference between synchronous and asynchronous opeartion of a distributed file system. Though a synchronous distributed file system has the preference because of reliability it also imposes certain limitations with respect to scalability. What would be, from your expertise, the way to go on this? I'm looking forward to your replies. Thanks in advance! :) With kind regards, Tim van Elteren

• Storing Windows Updates for reuse

  - by Saiyine

  At work we update lots of computers using Windows Update. Windows XP and 7 all day long, rarely some Vista. We do it through a corporate proxy, as connecting them to a domain to build a Wsus server is out of the question, so we download about two gigabytes a day of the very same updates everyday. I've tried WSUS Offline. It's pretty complete but when it finishes it's common to be still missing hundreds of megabytes of updates, because its intention is not to fully update a system but to install the critical updates, as the developers explain in the forums. Now I'm trying with Autoupdater. It's far worse, with poor capabilities for non-English Windows XP, but at least it gives the option to install non critical updates in Windows 7. It still misses hundres of megabytes of updates after fully updating the system. And finally, both doesn't install the driver related updates of Windows 7, so they at most save us a couple of hundreds of megabytes and a reboot (with the associated login to the computer and to the proxy) out of three or four. So, is it possible to somewhat extract the installed updates in a Windows 7 system and not having to download the same updates again and again at least with machines with the same hardware? Or even better, a generic package with all the updates?

• Pushing Windows Store apps silently

  - by seagull

  As part of a requirement I have been issued, I seek the ability to push apps from the Windows Store (.appx) to remote users. The framework surrounding the data transmission is sorted; What I need to know is if there is a script that can be sent out along with a URI or the package proper to facilitate installation on the user-side of the Windows Store app. I am well aware that numerous guides exist from Microsoft on pushing out Line-of-Business (LOB) (AKA Enterprise) applications -- that is, apps that have been developed in-house and are not for the consumption of the Windows store. This is inappropriate for my requirement, however; the customer wants their clients to receive apps that appear currently on the Windows Store, and for them to be installed in a silent manner. I've seen this guide; http://blogs.technet.com/b/keithmayer/archive/2013/02/25/step-by-step-deploying-windows-8-apps-with-system-center-2012-service-pack-1.aspx, which details doing exactly this, but it is only applicable to machines that are administered by a system running Windows Server 2012 R2 with the 'System Center 2012' bundle installed. The systems I target are considerably more decentralised than this, making this guide inappropriate. I have a hunch that Microsoft have deliberately designed the Windows Store to be this way, but I figured I ought to ask around before I resign myself to the requirement. Much obliged

• Frequency of RAM

  - by Vignesh Palani

  I have a very old system hp compaq dx2080. It had 1gb of RAM. I recently bought a EVM DDR2 1 GB PC RAM which had a clock rate of 667Mhz. I have dual booting windows 7 and 8. When I installed it, windows 7 was still using the older 1gb. It showed as 2 gb available and 1gb usable in system properties. I searched around and found that I can change it to max in the msconfig. I did so. I set it 2048. Still, it was using only 1gb. When, I switched to 8, it was using the 2gb. Now, for my question: My system only supported 553Mhz and 667Mhz RAM. In the BIOS, I saw that the new RAM was showing as 800Mhz. Rechecked using speccy and cpu-z. It showed different values between the two. The RAM is labeled as 667Mhz over it. No mistake in that. But, am I missing something? Please help. And, can I continue using it? My point again. There are only two slots.

• How do you avoid that server documentation gets out of sync with the actual setup?

  - by Frerich Raabe

  I'm a hobbyist maintaining a small FreeBSD server serving mail via IMAP - it's an exercise in server administration. The setup does have reasonably good documentation (in AsciiDoc format) which recently allowed another person to recreate the entire setup from scratch in less than 30 minutes. However, I noticed that after the initial setup, it easily happens that small changes done to the system (say: inetd gets disabbled, my IMAP server listens on an additional port for ManageSieve connections, a new router is added to the exim configuration) don't end up in the documentation immediately (if at all). My idea was to avoid this problem by (partially?) generating the documentation out of the configuration files and the comments therein - one way to implement this may be to put /etc and /usr/local/etc into some source code management system (say - git) and then run a script which regenerates the documentation on every commit. However, I'm not sure whether that would be overkill and/or too difficult to get right (after all, I don't want complete copies of the source files in my documentation but rather just the diffs). How do other people avoid that the server documentation gets outdated - is there a good way to keep them in sync automatically, or do you just have the discipline to update the documentation the same time you modify the system?

• Port(s) not forwarding?

  - by user11189

  I have cable internet service through Charter Communications and feed two desktop computers through a Linksys RP614v3 router. One system is my wife's running WinXP Home Edition and the other is mine, running Vista Home Premium (sp1). I have port forwarding configured in the Linksys so I can access the Vista system remotely using TightVNC. Initially, it worked great and I was able to remotely tend email and access local files while out of town for work. Lately, the cable internet service appears to flicker intermittently and upon return, my Mailwasher program loses ability to access the net and I've been unable to make the remote connection. When I reset the port forwarded for email in the router control panel, Mailwasher functionality returns but as I'm home when that happens, I have no easy way to check remote access until the next time I'm on the road or at work. I'm at my wit's end -- the TightVNC client accesses fine from my wife's system from behind the modem/router setup but I don't know how to maintain whatever gets reset when I fiddle with the control panel and the need to do so at all is new. I accessed it fine for a week off and on while out of town a month ago and now I can't leave home and access it from work an hour later.

• which virtualization technology is right for me?

  - by Chris

  I need a little help with this getting this sorted out. I want to setup a linux virtual server that I can use to run both sever and desktop systems. I want a linux system that is minimalist in nature as all the main os will be doing is acting as a hypervisor. The system I'm trying to setup will be running a file server, windows 7, ubuntu 10.04, windows xp and a firewall/gateway security system. All the client OS'es accessing and storing files on the file server. Also all network traffic will be routed through the gateway guest os. The file sever will need direct disk access while the other guests can run one disk images. All of this will be running on the same computer so I wont be romoting in to access the guests OS'es. Also if possible I would like to be able to use my triple head setup in the guest OS'es. I've looked at Xen, kvm and virtualbox but I don't know which is the best for me. I'm really debating between kvm and virtual box as kvm seem to support direct hardware access.

• less maximum buffer size?

  - by Tyzoid

  I was messing around with my system and found a novel way to use up memory, but it seems that the less command only holds a limited amount of data before stopping/killing the command. To test, run (careful! uses lots of system memory very fast!) $ cat /dev/zero | less From my testing, it looks like the command is killed after less reaches 2.5 gigabytes of memory, but I can't find anything in the man page that suggests that it would limit it in such a way. In addition, I couldn't find any documentation via the google on the subject. Any light to this quite surprising discovery would be great!

• Windows disk change monitoring for malware analysis

  - by SuperDuck

  Not sure if this question belongs to here, because it has some relations with 'serverfault' (system backups) and 'stackoverflow' (software analysis). I'm looking for a solution to monitor disk changes on a Windows system and selectively revert them. It should be able to handle live files like registry parts, so may need to be an offline backup software. It shouldn't silently pass over files which the current admin user doesn't have permissions on (files with no permission entries or owned by the 'system' user) Registry change tracking would be a bonus but is not a requirement I use virtual machines for malware analysis, there is even no solution to list file changes in disk snapshot files (delta VMDK). I currently use Ashampoo for monitoring changes. Though it's the best one between similars, it's not a good software and hasn't really evolved in many 'platinum', 'deluxe' versions released in the last 10 years (it even used non-resizable windows until the latest version). The real problem is it misses some disk / registry changes. Perhaps it only compares modification dates and doesn't catch a change if the dates are preserved. So, I think the solution should compare files using hashes, or file sizes at least. There are numerous backup software out there and I'm sure one can handle this, offline or online.

• clocksource tsc unstable

  - by amorfis

  Ok, now I have real server fault ;) After some time from booting (about one minute) my server hangs. All I can do is hard reset. Then after restart in /var/log/kern.log I can find: Jul 29 22:38:57 leonidas kernel: [ 90.729598] longhaul: Failed to set requested frequency!

• The suggested way to handle pip(easy_install) with homebrew?

  - by Drake

  I know there are brew-gem and brew-pip but it is still really easy to get confused. Let's say my Mac OS X is 10.7.2. There are at least, as far as I know, 3 locations for Python modules (assume 2.7): /System/Library/Frameworks/Python.framework/Versions/2.7/ /Library/Python/2.7/site-packages /usr/local/lib/python2.7/site-packages/ (controlled within homebrew) For some Python modules, pip install them into 2, the so-called local/customized Python module location, and everything looks and works great. Ex, readline by *easy_install* (ipython suggested me to install readline by *easy_install* instead of pip) For some, it would try to install some miscellaneous files (ex, man, doc, ...) into system-wide location, which requires sudo! Ex, ipython insisted on installing man and doc into /System/Library/Frameworks/Python.framework/Versions/2.7/share/, which violates permission issue and all I can do is to use sudo. For some Python modules installed by brew, they are symbolic linked to /usr/local/lib/python2.7/site-packages/. Everything seems great except that you have to remember to add this location into PYTHONPATH. I am wondering any suggested and uniform way to handle those mass, or any explanation to make those stuff crystal clear.

• Is there a utility to visualise / isolate and watch application calls

  - by MyStream

  Note: I'm not sure what to search for so guidance on that may be just as valuable as an answer. I'm looking for a way to visually compare activity of two applications (in this case a webserver with php communicating with the system or mysql or network devices, etc) such that I can compare the performance at a glance. I know there are tools to generate data dumps from benchmarks for apache and some available for php for tracing that you can dump and analyse but what I'm looking for is something that can report performance metrics visually from data on calls (what called what, how long did it take, how much memory did it consume, how can that be represented visually in a call stack) and present it graphically as if it were a topology or layered visual with different elements of system calls occupying different layers. A typical visual may consist of (e.g. using swim diagrams as just one analogy): Network (details here relevant to network diagnostics) | ^ back out v | Linux (details here related to firewall/routing diagnostics) ^ back to network | | V ^ back to system Apache (details here related to web request) | | ^ response to V | apache PHP (etc) PHP---------->other accesses to php files/resources----- | ^ v | MySQL (total time) MySQL | ^ V | Each call listed + time + tables hit/record returned My aim would be to be able to 'inspect' a request/range of requests over a period of time to see what constituted the activity at that point in time and trace it from beginning to end as a diagnostic tool. Is there any such work in this direction? I realise it would be intensive on the server, but the intention is to benchmark and analyse processes against each other for both educational and professional reasons and a visual aid is a great eye-opener compared to raw statistics or dozens of discrete activity vs time graphs. It's hard to show the full cycle. Any pointers welcome. Thanks!
