• XenServer/Center: Shared SRs for hosts not in same pool?

  - by 3molo

  I would like to use the same SRs on XenServer hosts that are not able to be part of the same pool (because of not having the exact same cpu feature set, if I understand it correctly) in order to share templates, being able to (manually) start a host on another node, backing up running hosts on other hardware etc etc. The technology for SR can be any of iSCSI, NFS or CIFS, iSCSI would obviously be preferred. Trying to add an iSCSI volume renders a "This LUN is already in use as SR iSCSI - Shared Storage on pool xxxxxx.". Adding a NFS share on one XS host, creating a template there and then checking another XS host reveals they don't agree on used space etc. Coming from a vSphere world this is quite baffling, but if these are limitations then I will have to rethink some of the concepts for this low budget project.

• Macbook Pro + Windows 7 (bootcamp) = Terrible battery life

  - by Scott Beeson

  I recently put Windows 7 Ultimate x64 on my wife's Macbook pro because of some software she bought for her business. Since then, the battery life has been abysmal. I've identified and researched one of the problems, which is display brightness. There is no brightness control in the windows power options, but I did manually turn it down in Bootcamp. However, it is still reporting very low battery life estimates. I'm wondering if this is because Windows thinks the display is at full brightness. Can anyone shed any light on this? (Pun intended). Also, are there any other things to look out for that may improve the battery life? (I mean in the context of Mac + Windows, not in general)

• Migrating to Windows Server 2008 R2 Domain Controllers - a few Questions/Issues

  - by Chris

  Ok so here's our setup: We have 2 Windows 2003 Domain Controllers. I am trying to replace them with Windows 2008 R2. The 2003 servers are named DC01 and DC02. The 2008 R2 servers are DC1 and DC2. I prepared the Windows Server 2003 Forest Schema for a Domain Controller that runs Windows Server 2008 or Windows Server 2008 R2. Then with both of the new servers up as member servers I ran dcpromo on DC1 using the advanced option and added it successfully to my existing domain. It's roles are GC, DNS and Active Directory Domain Services. I transferred The PDC Emulator, RID Pool Manager, and Infrastructure Master roles to DC1. The Schema Master and Domain Naming master are still on DC01. The first issue that I'm encountering is when I dcpromo the DC2 and select "Replicate data over the network from and existing domain controller" I select that I want to replicate from DC1 and I get the following error: Failed to identify the requested replica partner (dc1.xxx.org) as a valid domain controller with a machine account for (DC2$). This is likely due to either the machine account not being replicated to this domain controller because of replication latency or the domain controller not advertising the Active Directory Domain Services. Please consider retrying the operation with \dc01.xxx.org as the replica partner. "The server is unwilling to process the request. Is this because the Schema Master and Domain Naming Master roles are still on the old DC01? And if so, if I transfer Schema Master and Domain Naming Master roles to DC1 what is the risk or breaking my AD? I'm a little paranoid because this process HAS to be transparent. ANY down time or interruption will result in me getting a verbal ass kicking from my I.T. Director. Both of the new servers DNS point the the old DNS servers (DC01 and DC02) not themselves by the way.

• Is there a common X-Header for RFC 2821 "MAIL FROM"? Should it be DKIM signed?

  - by makerofthings7

  w.r.t. the difference between RFC2821 MAIL From and RFC2822 FROM I'm considering having my MTA add a header specifying what was sent in the MAIL FROM portion of the envelope. The RFC2821 header is used for receiving email bouncebacks, and is the header that is checked in SPF and some SenderID configurations. The goal is to make it easier for diagnostics and debugging by having this low level information in the email header. What is an acceptable name for this SMTP header? Should this header be signed by DKIM? Is there any reason why it shouldn't be signed?

• Sound problems in Windows 7

  - by Plastkort

  hi! I hope I reached the correct forum for this question. I have a media computer with a third party audio card (Soundblaster audigy SE) I use a coaxial digital audio cable connected to a Onkyo TX SR508. if I use normal audio, the sound seems very low, I have to set volume atleast to 62 in my amplifier to hear anything, however if I set digital SPDIF I have no means of controlling the audio volume from the PC (only from the amplifier) and this can be nasty if I toggle between movies that uses Digital AC3/THX and movies wihtouth, if I look at movies capable of AC3 the volume gets VERY loud if amp is set to 62, 32 is more than enough volume when using passthrough. so this bothers me is how can I get the same amount of volume with or without digital output? I tried also other soundcards, internal red light Digital audio cable... if I connect to my television I get ok sound on any sound source via HDMI... help :)

• Dell Studio XPS 16 Runs Hot

  - by dtbarne

  Specs: 1920x1080 i7 1.6 GHz quad core 6GB RAM 1GB ATI Radeon HD 6570M/5700 Series 500GB 7200rpm Hard Drive Love this laptop for many reasons, but it constantly runs hot (CPU is low 70s with basic tasks and often 80+ is not uncommon) and I'm finding it too much to deal with. The laptop feels very hot (almost too hot for a lap) and often gets so hot that the OS slows down or freezes altogether. I've tried cleaning it out and even replacing the thermal paste. I often use an external cooler, but it only helps 3-5 degrees and it's a pain to have to use. I've come to the conclusion that it just runs hot. I have two questions: What is to blame? The i7 processor, the gfx card, or is it just that this laptop has poor cooling? Does the Dell XPS 15 run cooler? I'm looking at replacing my current laptop, but I don't want to run into the same problem.

• Dye Sub printer with specific prints remaining - can I command-line query this?

  - by Jason N

  Hey, I've got a Sony Dye-Sub printer that holds ink/paper sets - i.e. a very certain amount of ink and paper for ~200 prints. This information is available to me from within Control Panel Printers Preferences Printer Device Information (i.e. current 189 remaining prints). Any way I can perhaps get this information from the command line? I'd like to write a little program to tell me when the number of prints gets low (i.e. < 20), rather than suffer the annoying Windows "run out of paper" popup. I've found the Windows VBScript print utilities, but can't seem to find the request I need for this. Any suggestions? Jason

• Tool to bulk speed up/convert an audio file

  - by User1

  I want to listen to certain podcasts on my phone but I have two common problems: The audio is in some weird format (some don't play on my phone). The audio is slow. I want to use something like sox or avconv to bulk convert the files. Since this is just voice and going on a cell phone, small low-quality files would be best for me. I had some good success using avconv: avconv -i weird.wma normal.ogg Unforunately, this command creates an enormous ogg file and I can't get it play faster. Ideally, this particular file would play at 170% of the original speed.

• High disk time on sql-server

  - by Patrik

  Hi We have a dedicated sql-server 2008 r2 enterprise edition. The setup is: D: (data files) - stored on local ssd disks (not the same disks as log files) (raid 10) E: (log files) - stored on local ssd disks (not the same disks as data files) (raid 1) F: (transaction log backup) - stored remote on a SAN Today we moved our log files to new disks (from F: to E:). From a shared volume ( F:(SAN)) to dedicated local disks (E:). What then happend was that the "disk time", "avg. transfer time" and "avg disk write queue length" increased on the volume where we have the data files (D:) (not on the volume where the log files are located). The data volume and log volume does not share disks, however they share the same controller card. "Disk idle time" is low for all volumes. One thought is ofcourse that the controller card might be overloaded. But, we need more ideas on where the problem might be.

• Debian Linux server hangs after a week or so

  - by Alex Flo

  I have 2 Debian Linux 6.0.4 servers that have a strange behaviour: after 5-7-10 days they hang. By this I mean the servers need to be restarted and before that ping won't answer. I've been struggling with this problem for a couple of months now and here's some thoughts/what I tried without being able to solve the problem. I changed the RAM on a server. Being 2 different servers I doubt that it could be something related to hardware as a 3rd identical server won't have this problem. I logged the server load and when it crashes the load is fine (quite low) I cannot find anything in the server logs, logs are fine till the server freezes. I don't have access to console unfortunately. While I have years of admin experience I have never encountered such an issue and right now I have no idea where else to investigate. If you have an idea of what I could try in order to fix the problem please share it with me:-)

• Memory modules not running at rated speeds.

  - by Wesley

  Hi all, I'm having some odd memory issues with my build. Here are my specs right now: QDI Superb 4 motherboard Intel Pentium 4 Northwood 2.4GHz (512KB L2, 533MHz FSB) 3x 256MB PC2100 DDR266 RAM 16MB NVIDIA TNT2 Pro AGP Seagate 80GB IDE HDD Generic USB 2.0 PCI Generic Modem PCI Bestec 250W PSU To be even more specific, here are the current brands and models of each module: Kingston KVR266X64C25/256 Samsung PC2100U-25331-Z SMART SM5643285D4N0CHM0H Supposedly, they are all PC2100 266MHz modules with a latency of 2.5. Looking in Speccy, the Kingston module is somehow running at a speed of PC2300 ~284MHz. I've never overclocked RAM at all as I don't know how to. However, when I first started the computer, I had the SMART module in place first and then reset the BIOS settings, including the integrated overclocking options. However, this still doesn't explain why the Kingston module runs at a higher speed than the SMART and Samsung module. Why is it like this? On a side note, where could I find the motherboard manual for the QDI Superb 4? Thanks in advance.

• "Can't find root filesystem / error mounting /dev/root" when booting to new kernel

  - by salparadise

  I am trying to upgrade my kernel from 2.6.18-274 to 2.6.39 for some wireless card drivers. When I boot into the new kernel I get the "Can't find root filesystem / error mounting /dev/root" googling led me to this page http://fedoraproject.org/wiki/Common_kernel_problems#Can.27t_find_root_filesystem_.2F_error_mounting_.2Fdev.2Froot From what I am reading seems to be an issue with a driver for my SATA controller or HD, but I can't find what option I need to add to the kernel. Doing a diff from the old initrd to the new one gives me the following: root-> diff /tmp/kafter /tmp/kbefore 6a7,8 > lib/dm-message.ko > lib/dm-region_hash.ko 8a11 > lib/dm-raid45.ko 13d15 < lib/dm-region-hash.ko 16a19 > lib/dm-mem-cache.ko Do I need any of those? not sure if I would need dm-raid45.ko as I am not running a raid. I have the same SATA and IDE options configured for both kernels so not sure what else to look for, any help is appreciated.

• How to calculate bandwidth limits per user on WiFi network

  - by Lars

  A typical 802.11g access point can provide around 25 Mbps of bandwidth. How is the bandwidth shared among the users? Furthermore, how many users can be served by a single access point using 802.11g in an environment with low interference, and average web activity from the users? The goal is to use bandwidth limitation to avoid starvation for some users in case some of the users start to download a file or stream HD video or some other bandwidth intensive activity. Can someone break down the math on this?

• Windows 7 Wakeup from Sleep then Shutdown

  - by Kevin Hua

  Is this caused by low battery? I have an Asus UX31A, and I left it unattended. As usual, in 5 minutes, it went to sleep mode with the lid still open. I came back a couple hours later, and I noticed the laptop was off. I was still able to turn it on by manually pressing the power button (battery was at 2% though), but I don't understand why it shut off. If it was in sleep mode and the battery was near depletion, then wouldn't that result in a "Windows has recovered from an unexpected shutdown" upon boot? Does Windows have a mechanism to wake from sleep from a super critical battery level to shut down all programs and power down the system completely? I noticed that upon booting, firefox didn't give a fit about improper shutdown. Here are my power settings btw, powercfg -h off has been ran, so hibernation is off. And here is the event log: http://www.mediafire.com/download.php?lbfhl21g0nj2adi

• Am I getting the right memory for my motherboard?

  - by Daniel Carvalho

  Hi technophiles; I have a Gigabyte GA-EP45-DS motherboard. Also, the memory that came with my computer was two Transcend aXe RAM 1066MHZ 1GB modules. The thing is, I noticed that my motherboard has "DDR2 1200" written on it. This concerns me, have I bought slower memory than my computer is supposed to have ideally? Now, I'm not super concerned at a granular level about the best optimal RAM with the best CAS latency etc... but I do hope at least that I've got the right speed. Now, as far as I know, there is no such thing as ram at 1200MHZ? Am I right? You see, because I'm thinking of getting more RAM now, before I can't find the same type or speed any-more and just want to make sure it's the right thing. Furthermore, if the memory is slower than what I should be getting for my motherboard, what RAM should I be getting, and will that new RAM play nice with my old RAM? If I get new RAM at a different speed, would it be better / more beneficial performance-wise to omit the old RAM because of how the whole DUAL channel RAM thing works? I'm not too clued up on this area. Thanks chiefs.

• Slow Web Performance on two Windows 2008 R2 Terminal Servers

  - by Frank Owen

  We have two Windows 2008 R2 servers that we use for agents to log into to access our customers systems. Saturday morning we received complaints that on both servers the web is running horribly slow. This happens on all websites and the majority of the time the web site times out trying to load. Other users located at the same site but using their desktop machine do not see any issue. We have rebooted the boxes and checked settings and cannot find the cause. The CPU/Memory/Network/Disk Space use on the server is very low. I thought it might have been a MS update causing the issue but it appears the last update was applied in January. We have rebooted both boxes and I am in process of trying a different browser. Any ideas what could be causing this?

• How to increase Remote Desktop resolution?

  - by BugAlert

  I'm using Windows 7 on a PC and connect to it via Remote Desktop Connection for Mac by MS, using a Mac. On the Mac, I have a 27" Display with 2560 x 1440 px resolution. The PC has a high performance graphics card (one of those that needs an additional power supply). Both machines are connected via network cable to a router. So network should be insanely fast. However, the max resolution I can get is 1400 x 1050. The PC just has a old and bad 21" monitor connected to it. How can I increase the resolution to 2560 x 1440 to work fullscreen with the Apple LED Cinema Display via Remote Desktop? Maybe I shouldn't even ask, because I already experience some lag at the low resolution of 1400 x 1050. But I guess this can be resolved as well?

• How do I install and run Tomcat on port 80 as my only web server? (Rooted Ubuntu box)

  - by gav

  Hi All, tl;dr - I have a rooted linux box that I want to run tomcat on as a server (No Apache Web Server) how would you set this up avoiding common security pitfalls? I've written a Grails App that I want to run on a VPS I rent. The VPS has very little memory and I am using it for the sole purpose of running this application so I don't need the apache web server. This is my first venture into Server administration and I'm sure to fall into some well known traps. Should I use iptables to redirect requests from port 80 to 8080? Should I run tomcat as root or as it's own user? What configuration settings would be good for a low memory system expecting less than 10 concurrent users? Hopefully an easy one for you! Anyone who could link to a tutorial would be a personal hero destined for great things no doubt. Gav

• Copying Metadata Between Files in iTunes

  - by Levi Hackwith

  A while back, I converted some AVI files to .m4v files that would be playable on my iPhone. When I play these files on my PC using iTunes the quality is terrible because the resolution is so low. My solution is to convert the AVI's using Handbrake using the "Universal" preset; it works like a charm and I can now watch them both on my PC and iPhone. The Problem I want to import the newly converted files into my iTunes library and be able to copy the metadata (show, season (these are TV episodes) Description, etc) without having to manually copy and paste values from one file to another. Is it possible to just say "copy this file's metadata to this file"?

• If i make a mail server can i send bulk email?

  - by Jake Smith

  I work for a small company and we have fallen into the fad of "email campains" a.k.a Junk mail. So far the company has gotten a subscriber list from our website, and paid a good chunk of change for a emailer program. The problem is, Our list has close to 4,000 people on it and growing. with gmail only allowing 100 emails per account through on SMTP and I am on a tight budget so I cant hire anyone else. I was thinking of doing a dedicated mail server off of the website server we have running in the office. Is it possible? to make emails on your own server, and then send it through your own SMTP? if it is, what software would I need and is if free or low cost at least. We run a WAMP server, i set it up just for information, but i could switch it to lamp or whatever if need be. Thank you for your time and youre answers

• How to turn off power metering in HP ILO2?

  - by Baron Throw

  I have an issue with all of my RHEL 5.3 servers, where HP iLo2 power meter checks the power draw of the power supply on the server. However this gets passed to the /var/log/messages in our host, and eventually fills up the logs. Anyone have any idea how to completely disable power meter option in iLo? I checked google and iLo2 documentation provided from HP, but found nothing that tells you how to disable it / turn it off. Maybe some CLI command? Im not sure. The message is: Aug 18 10:11:03 KAMIL-SERVER1 ipstor_hwmond: IPSTOR||1408371063||E||11788||sensors||Power Meter = 108.000 Watts [ low=na high=na]

• EventID 1058 Code 5, Sysvol is subdir of Sysvol - how to fix?

  - by nulliusinverba

  I have been trying to resolve this error, like many others: The processing of Group Policy failed. Windows attempted to read the file \domain.local\SysVol\domain.local\Policies{3EF90CE1-6908-44EC-A750-F0BA70548600}\gpt.ini from a domain controller and was not successful. Group Policy settings may not be applied until this event is resolved. This issue may be transient and could be caused by one or more of the following: a) Name Resolution/Network Connectivity to the current domain controller. b) File Replication Service Latency (a file created on another domain controller has not replicated to the current domain controller). c) The Distributed File System (DFS) client has been disabled. Error code: 5 = Access Denied. The incredibly helpful post is this one (http://www.experts-exchange.com/OS/Microsoft_Operating_Systems/Server/2003_Server/A_1073-Diagnosing-and-repairing-Events-1030-and-1058.html). Quoting from this post: HERE IS A LIST OF POTENTIAL PROBLEMS THAT CAN LEAD TO 1030 AND 1058 EVENT ERRORS: --Sometimes the permissions of the file folders that contain Group policies (the Sysvol folder) can be corrupted. --Sometimes you have problems with NetBIOS: --Sometimes the GPO itself is corrupt, or you have a partial set of data for that GPO. --Sometimes you may have problems with File Replication Services, which almost always indicates a problem with DNS --Sysvol may be a subfolder of itself: Sysvol/Sysvol I have the problem listed where sysvol is a subfolder of sysvol. The directory structure is: -sysvol -domain -staging -staging areas -sysvol (shared as "\\server\sysvol") -domain.local -ClientAgent -Policies -scripts Interestingly, the second sysvol folder is the one that is shared as "\server\sysvol". This makes me confident this is the issue with the permissions and error code 5. Also interestingly, my server 2008 R2 servers can see it fine - my server 2008 servers cannot, and get the error. This is consistent across all my servers. This latter fact makes me uncertain what I need to do to fix this up. Do I, e.g., simply move the shared sysvol folder up a level to replace the non-shared one? Any help greatly appreciated. Cheers, Tim.

• AWS: Multi-region setup using single RDS instance

  - by Ion

  I'm trying to scale our web application (PHP, MySQL, memcache) in a multi-region scheme. Currently we are using a setup with two EC2 instances behind an ELB and an RDS instance, all of them in US-EAST (Virginia) region. We would like to have a presence in the EU (Ireland) region as well. This means at least a new EC2 instance there (identical to the others, serving the same application). I have copied the desired AMI, setup the new instance, setup a same ELB configuration (required for SSL termination) and configured latency-based routing in Route53. And it works as suggested. But, clients from EU have speed problems. This is due to the fact that the EU EC2 instances connect to the US-based RDS instance. As far as I know Amazon has not yet enabled RDS multi-region replication. Do you have any suggestions on how to properly speed up the whole setup while using the single RDS instance? Also, any ideas in general on how to scale things up? Ideally we would like to continue using the RDS technology for various reasons. Nevertheless, I am open to suggestions (I guess the next idea would be to host our own MySQL servers).
