• Exporting a VM running as a Domain Controller

  - by AndyM

  There is a Microsoft KB article that talks about best practices for running a DC on a VM. One of the notes is "Do not use the Export feature on a virtual machine that is running a domain controller". In order to export a VM, the VM needs to be turned off. If you turn off a DC VM, export it, import it on another server and then power the VM back on, there should be no risk as long as the original (exported) VM is never powered back on. Can someone explain to me why this isn't supported? After doing some searching on Google, the sites I found just regurgitated this line from the KB article, but didn't offer any explanation as to why this isn't supported.

• ARP replies contain wrong MAC address

  - by Jayen

  I've got a robot running linux with wired and wireless adapters. When I boot up, it connects to the wireless fine. When I assign an IP to the wired (either statically or with DHCP), it looks like it works. As in, ifconfig shows a proper IP and route shows proper routes. However, when I do an ARP request of the wired IP, the ARP reply contains the wireless MAC. ??? There's no bridge running on the robot, so why don't I get the wired MAC??? When the wire is disconnected, the wired IP replies to ping... Why is the robot replying over the wireless interface to IP requests on the wired???

• Debian: SSH: "PermitRootLogin=forced-commands-only" stopped working

  - by Brent

  I have several servers running Debian Lenny. Just recently I discovered the PermitRootLogin=forced-commands-only directive for ssh, which allows me to run a scripted rsync as root with an ssl key, without enabling more generalized root ssh access. However, last week this stopped working - it appears on all of my servers - and I can't figure out why. Everything continues to work fine with PermitRootLogin=yes, but I would prefer to block root logins - especially via passwords. The day it stopped working, we reconfigured some of the ports on one of our switches (which we later reverted), but I can't see that affecting this, since it still works with PermitRootLogin set to yes. How can I diagnose why the forced-commands-only directive has apparently stopped working?

• Windows cmd does not recognize xx.exe even though xx.exe is in system path

  - by July

  I installed 7-zip and add its directory to system path: C:\Program Files\7-Zip to PATH, from windows start-input cmd and press enter, Windows command line is started, i type 7z.exe, then press enter, it just run. However when i start command line this way: cmd.exe /c start {projectDir} /D{driveLetter} cmd /K then i type 7z.exe, it gives me error because it can not find 7z.exe. why and how to fix? P.S. 1. I'm on Win7. 2. For some other apps, the above way did works, that's why i'm so confused how bat works.

• What has changed to make it possible to develop USB3.0

  - by RoboShop

  Like I know the transfer speeds are vastly different. But I don't understand is why they are faster. And why couldn't they have implemented USB 3.0 when they released 1.0? Like what technical breakthrough was required to get transfer speeds that fast? Was it cost? capacities of computer? like they couldn't read the data fast enough? Although USB is still well below hard drive transfer speeds engineering breakthrough? They found some new material which could transfer at a faster rate? Was this in the cable itself? In the hardware?

• FCoE, on any Ethernet switch?

  - by javano

  I understand the concept of FCoE. I have looked at the Wikipedia page and looking at the layer 2 frame diagram, it looks like FCoE really should "just work" on any Ethernet switch, but is this really the case? If so, what do switches like Cisco's Nexus 5k or 6120P offer that normal switches don't (in specific relation to FCoE)? I am just using those two switches as examples. On the Nexus 5548UP page for example it says the following; Unified ports that support traditional Ethernet, Fibre Channel (FC),and Fibre Channel over Ethernet (FCoE) Well if FCoE runnins over regular Ethernet, that why does it support "Ethernet and Fibire Channel over Ethernet"? This is why I am curious as to weather FCoE will run on any Ethernet switch and these switches just support "bonus" features, or if you do indeed require a specialist switch. Thank you.

• LAN connection suddenly domain_not_set.invalid

  - by Liam Coates

  I went to work today - internet fine as always. Came back, dreaded yellow triangle. I can connect wirelessly like i am now on my tablet. Thats completely fine. But through LAN I get the domain_not_set.Invalid message if I renew my IP for example. It seems I just don't have a DNS. But I have literally not touched anything no ones even been in the house. Hows that happen? Any help on why only wireless works would be great, I am gonna buy a wireless adapter tomorrow for the interim but I would like to know why. Thanks.

• is my xml cached by IIS7?

  - by user22817

  Hi guys, I have a flashplayer on my website. Behind it, there is an xml file which keeps the configuration of the products shown on that flashplayer. I do not understand why, if i modify something in the xml config file, the flash player is not updated at that moment, but after hours... Do you know why? I have not defined any rule for output caching in IIS7 so there is probably something default? Of course, i've tried Ctrl+f5 but does not work. Thanks.

• Is it possible, and is it advisable, to host a mail server on a Windows Azure VM role?

  - by JcFx

  I know this question has been asked on various forums before, and that all the answer were negative, but many of the answers are quite old, and with Azure developing so quickly it seems useful to ask it again. Can we run a mail server (such as mailenable) on an Azure VM? And if not, why not? I've seen one posting on the MS forums (here) that suggests the IP of the Azure machine would be blacklisted as a source of spam. Why would this be (as opposed to hosting a mailserver on a dedicated box)?

• Setting permissions on user accounts

  - by Ron Porter

  We would like to lock a couple of accounts to prevent even domain admins from resetting the password without already knowing the current password. From what I can see in the permission sets, this looks possible. Anything I've found on the subject recommends against altering default permissions, but doesn't go into detail why. Assuming that domain admin retains the ability to reset passwords without knowing current passwords is it reasonable to prevent password resets on the domain admin account and maybe a couple of others? If not, why not?

• What ever happened to vim-full package that used to be available in ubuntu?

  - by stephenmm

  Why was it removed and is there a way to get it? I know about this post but I am curious as to why it would have been removed? Also if you do an install like this: apt-get install vim vim-scripts vim-doc vim-latexsuite vim-gui-common vim-gnome What is actually happening? Are there different versions of vim installed or does it compile vim with all those options or ...??? Sorry about the multiple questions here but it would seem silly to break them out into individual questions since they are all very related. BTW I am using 10.04 LTS

• Unable to set NTFS permissions for ApplicationPoolIdentity on Windows 2008 SP2

  - by Kev

  On Windows 2008 R2 I am able to set NTFS permissions for an application pool's synthesised ApplicationPoolIdentity account thus: ICACLS d:\websites\site1\www /grant "IIS AppPool\site1":(CI)(OI)(M) The website's application pool is named site1 and is configured to run as ApplicationPoolIdentity. The site's authentication is also configured to authenticate as ApplicationPoolIdentity. I've done this a thousand times on Windows 2008 Standard Edition R2 with never a hitch. However if I try to do the same in Windows 2008 Standard Edition SP2 I get the error: IIS AppPool\site1: No mapping between account names and security IDs was done. Successfully processed 0 files; Failed processing 1 files I also notice that this fails if I try to set permissions for the application pool identity via the security GUI as well. I've seen this before and a reboot has cleared this issue but I'd like to know why this happens periodically. Googling around suggests other folks have hit this problem but there's never a satisfactory explanation. Why would this be?

• CentOS ISO DVD self-disc-check failing

  - by Jakobud

  I downloaded a CentOS 5.4 DVD ISO from one of the official mirrors. The MD5 sum is correct for the iso file that was downloaded. I burned the ISO onto a DVD+R using ImgBurn. I got no errors during the burning process and it says it finished burning successfully. When booting a server using this DVD to install CentOS on it, the first thing I did was run the self-disc-check (where it checks the files to make sure its genuine, etc). It failed. Didn't really say why. Am I doing something wrong here? Or is there someplace I can see why its failing? If the MD5 is correct and I don't get any burning errors, how can it be failing its own self-check mechanism?

• How can I evaluate the best choice of archive format for compressing files?

  - by Mehrdad

  In general, I've observed the following: Linux-y files or tools use bzip2 or gzip for distributing archives Windows-y files or tools use ZIP for distributing archives Many people use 7-Zip for creating and distributing their own archives Questions: What are the advantages and disadvantages of these formats, all of which appear to be open formats? When/why should I choose one (say, 7-Zip) over another (say, ZIP)? Why does the trend above appear to hold, even though all of these are portable formats? Are there any particular advantages to using a particular archive format on a particular platform?

• Time issues on the Network -- How to find the Root Cause

  - by Jeff

  A number of application servers started erroring out in my domain. Troubleshooting led me to a missconfiguration of NTP. I fixed the issue, but I don't know how the issue arose in the first place. The only errors I can find are System Error: 1097 Source: useenv System Error: 1058 Source: useenv System Error: 1030 Source: useenv System Error: 1000 Source: mmc How else can I find out why NTP started acting up on my domain? Is there any troubleshooting steps to diagnose why my DC started pulling from a random timeserver with the wrong time? EDIT: Current issue actually remains: the two 2003 DCs are not syncing with the PDC (a 2k8 box). w32tm /resync -- The computer did not resync because no time data was available.

• Understanding ESXi and Memory Usage

  - by John

  Hi, I am currently testing VMWare ESXi on a test machine. My host machine has 4gigs of ram. I have three guests and each is assigned a memory limit of 1 GB (and only 512 MB reserved). The host summary screen shows a memory capacity of 4082.55 MB and a usage of 2828 MB with two guests running. This seems to make sense, two gigs for each VM plus an overhead for the host. 800MB seems high but that is still reasonable. But on the Resource Allocation Screen I see a memory capacity of 2356 MB and an available capacity of 596 MB. Under the configuration tab, memory link I see a physical total of 4082.5 MB, System of 531.5 MB and VM of 3551.0 MB. I have only allocated my VMs for a gig each, and with two VMs running they are taking up almost two times the amount of ram allocated. Why is this, and why does the Resource Allocation screen short change me so much?

• How to have a soft-real-time process in presense of heavily swapping IO-intensive background load?

  - by Vi

  schedtool: PID 32301: PRIO 4, POLICY R: SCHED_RR , NICE -20, AFFINITY 0xf ionice: realtime: prio 4 But the music is stumbling anyway. Background load is low prio (SCHED_IDLEPRIO, idle ionice), but uses a lot of memory (more than is physically available) and does a lot of IO and calculations. Latencytop shows about 1500ms for: Following symlink Writing buffer to disk (sync) Page fault Writing a page to disk both for the bg load and for unrelated processes. Load average is 10 and counting. Why cannot it allocate, for example, 200MHZ of one of the cores and 32M of memory and not less than once per second opportunity for IO for mplayer to make it happy while continuing calculations on the background? Or: why it cannot leave background task and swap loving each other but keeping the rest of the system as if there were no background load? How to have RT processes AND heavy bg load simultaneously (without of virtual machines)?

• What about IPv4 class E?

  - by Luc

  IPv4's class E network (240.0.0.0/4) contains 268 million addresses. Despite the advertisements for IPv6, claiming we have ran out of address space, this block ironically still claims to be "Reserved for future use". Why hasn't this block been freed up yet? Of course, IPv6 should be promoted instead of freeing up more IPv4 addresses, but we've seen the address shortage coming for years. There has even been a time they weren't sure there was enough time to develop IPv6 before we would run out of addresses. Why didn't they free up this block already? And is there any chance these addresses will be used in the future, like when IPv6 is fairly widely implemented but we still need IPv4 for backwards compatibility? It will be phased out regardless, but then ISPs don't have to employ NAT for IPv4 compatibility.

• Is there a reason the partition tool GParted doesn't show a percentage finish number initially?

  - by Jian Lin

  I am using GParted more, and it seems to do a reliable work. I just wonder why if the tasks is to resize a 250GB partition to 190GB, and then create a new partition, the first 10, 15 minutes, there is only a blue bar moving left and right, but there won't be an indicator showing how many percent is done. Then after that 10 to 15 minutes, it does show 1:05:00 left to finish the job. Update: at first I thought there is no percentage or time remaining at all... but after waiting for 10, 15 mintues, it does show. I just wonder why it didn't show at first.

• Very high memory usage, but not claimed by any process?

  - by SharkWipf

  While stress-testing LVM on one of our Debian servers, I came across this issue where memory would fill up a lot to the point where it would run the server out of memory, but no process would claim the memory. See http://i.imgur.com/cLn5ZHS.png, and see http://serverfault.com/a/449102/125894 for an explanation on the colors used in htop. Why is this happening? And is there any way to see what process is using the memory? Htop is configured not to hide any processes, so what is it that htop is missing? In this particular case, I can fairly certainly say that it is caused, directly or indirectly, by lvmcreate, lvmremove or dmsetup, as I was stress-testing that. Do note that this question is not about solving the LVM problem, but about why the memory isn't claimed by any process. Stopping all LVM commands does bring the memory back down to <600MB.

• Chrome Crash Investigation

  - by iamcreasy

  Chrome is crashing very very frequently(every 2-3 min). It becomes irresponsive. How can I start investigate why this is crashing so much? It feels to me that certain components of some web pages are triggering the crash. I also checked "C:\Users\irfan\AppData\Local\Google\CrashReports", but this folder is empty. Some sort of process tacking tool, and keep an eye out for which request is being made just before the crash, or something like that. Any software suggestion? Im using Windows 7. Please don't suggest, reinstall chrome. I want to know why this is happening.

• Tomcat / Railo stop responding with no error output

  - by andrewdixon

  This is going to sound very vague and I'm sure it will be voted down for not giving enough information however I don't really have any to give as you will see. We have an AWS instance running Amazon Linux, Apache, Tomcat and Railo and from time to time the Tomcat/Railo simply stops responding to requests and there are no errors output in the catalina.out file or any of the other log files in the Tomcat logs directory. When I issue the command to restart Tomcat/Railo the restart scripts sits there for a while then says that Tomcat has not responded so it has killed it off and then it starts up again and everything is fine until it happens again, anything from a couple of minutes to a couple of days later. I have done my best to check other logs on the server but have found no messages at all to indicate why Tomcat/Railo has given up and stopped responding. Can anyone suggest any reason why it might be doing this and / or any other log file(s) that we could check to see what is happening. Thanks. Andrew.

• What is the value/cost of enabling "spread spectrum clocking" on my hard drives?

  - by Stu Thompson

  I'm building up a biggish NAS box (10x WD RE4 2TB SATA RAID10) and ran into some problems. During the course of my research, debugging, investigations, etc, I discovered a jumper on the physical drives labeled "spread spectrum clocking". After some googling about this on teh internets, it seems to be a feature that some suggest (without reference or explanation) enabling in 'a storage configuration' that makes the drive less sussesptable to EMI. But why? I've got three core questions: Why is this feature not enabled by default? What are the actual benefits? Are there any costs?
