• SQL Server Installation: Is it 32 or 64 bit?

  - by CapBBeard

  Recently I was performing an OS upgrade on one of our DB servers, moving from Server 2003 to Server 2008. The DBMS is SQL Server 2005. While reinstalling SQL on the new Windows installation, I went to another of our DB servers to verify a couple of settings. Now, I always thought this second server was Server 2003 x64 + SQL 2005 x64 (from what I'd been told), but I now have my doubts about this. I now suspect that it is in fact only 32 bit SQL, however I'd like to verify this. Here's some details: The OS is definitely 64 bit. xp_msver shows Platform as NT INTEL X86 SELECT @@VERSION shows Microsoft SQL Server 2005 - 9.00.4035.00 (Intel X86)... However sqlservr.exe is not shown with '* 32' in taskmgr, does anyone know why this is the case, if it is in fact 32 bit as claimed? Despite this, it does seem to be running out of the x86 program files folder. If I do the same checks on a confirmed 64 bit installation, it does give back the expected 64 bit readings, which can only prove that this server in question is only running in 32 bit. Now, that being the case, the question arises about how much memory this '32 bit' install can use. Task manager reports about 3.5GB memory usage for sqlservr.exe (The server has 16GB physical). I suspect that AWE has not been configured at all, and therefore the server will be significantly under-utilised (remembering that the OS is 64 bit) if SQL is simply using a 32bit address space. Is this assumption correct? I feel the server should have SQL reinstalled as 64 bit in order to fully utilise the hardware platform, however it is currently heavily in production; this will be no easy task. I suspect we may just have to configure AWE correctly and let it be for the time being (Unless this is a bad idea?). I apologise that this question is a little vague/lost; I'm no SQL expert, just trying to get a handle on what's going on here.

• Slow parity initialization of RAID-5 array on HP Smart Array 411 controller

  - by Rob Nicholson

  On 29th October 2011, I built a RAID-5 array using 4 x 146.8GB Seagate SAS ST3146855SS drives running at 15k connected to a PowerEdge R515 with HP Smart Array P411 controller running Windows 2008 (so nothing particularly unusual). I know that parity initialisation of a RAID-5 array can take some time but it's still running after 2.5 weeks which seems a little unusual. I'd previously built another array on the same controller using 4 x 2TB SATA-2 drives and that did take a while to complete but a) I'm sure it was less than 2.5 weeks, b) that array was ~12 times bigger and c) during initialization, the percentrage slowly increased each day. At the moment, the status display for this new 2nd array simply says "Parity Initialization Status: In Progress" and it's said that since the start. It's this lack of change on the status that worries me the most - feels like it's not actually doing anything. Do you think something has gone wrong or am I being unpatient and for some reason, the status not increasing is normal? I kind of expected a much smaller array on faster drives (15k SAS versus 7.5k SATA-2) to build in a few days. This is our primary SAN running StarWind so my "have a play" options are very limited. This 2nd array is currently in use for one small virtual disk so I could shut the target machine down, move the virtual disk to another drive and try rebuilding.

• iis7 large worker process request queue creating process blocking aspnet.config & machine.config amended (bottleneck)

  - by scott_lotus

  ASP.net 2.0 app .net 2.0 framework IIS7 I am seeing a large queue of "requests" appear under the "worker process" option. State recorded appear to be Authenticate Request and Execute Request Handles more than anything else. I have amended aspnet.config in C:\Windows\Microsoft.NET\Framework64\v2.0.50727 (32 bit path and 64 bit path) to include: maxConcurrentRequestsPerCPU="50000" maxConcurrentThreadsPerCPU="0" requestQueueLimit="50000" I have amended machine.config in C:\Windows\Microsoft.NET\Framework64\v2.0.50727\CONFIG (32 bit and 64 bit path) to include: autoConfig="true" maxIoThreads="100" maxWorkerThreads="100" minIoThreads="50" minWorkerThreads="50" minFreeThreads="176" minLocalRequestFreeThreads="152" Still i get the issue. The issue manifestes itself as a large number of processes in the Worker Process queue. Number of current connections to the website display 500 when this issue occurs. I dont think i have seen concurrent connections over 500 without this issue occurring. Web application slows as the request block. Refreshing the app pool resolves for a while (as expected) as the load is spread between the two pools. Application pool in question FIXED REQUEST have been set to refresh on 50000. Thank you for any help. Scott quick edit to say hmm, my develeopers are telling me the project was built with .net 3.5 framework. Looking at C:\Windows\Microsoft.NET\Framework64\v3.5 there does not appear to be a ASPNET.CONFIG or a MACHINE.CONFIG .... is there a 3.5 equivalent ? after a little searching apparenetly 3.5 uses the 2.0 framework files that 3.5 is missing. So back to the original question , where is my bottleneck ?

• windows 8.1 does not boot after CHKDSK command

  - by sepehr

  I had problem with Windows 8.1 high Disk usage so in order to solve , searched forums. A voted answer suggested to use CHKDSK command as follow: run command prompt and as administrator type code snippet below: CHKDSK /f /v /b C: (I can not remember accurately) CHKDSK printed : can not run CHKDSK right now , would you like to schedule C drive to be checked next time windows starts? (Y/N) my response was "Y" ,please ! Following this suggestion not only didn't solve my problem as expected but also added another one ! The next time system booted, after windows authentication I just could see a black screen and mouse pointer. So I force shut downed the system and tried to start windows again. This time , windows got stuck in Scanning and Repairing on 22% for around 3 hours so I got tired and forced shut downed again. is CHKDSK source of Scanning and Repairing problem or they are discrete ? is there any hope to overcome this problem without re-installing windows ? can any one else run CHKDSK on newer versions of windows without problem? is CHKDSK effective but inefficient ?(it finally get to end but will take a long time) If yes, how much time does it take? I also have Linux Ubuntu 14.04 installed along side windows.

• Linking to a chat room via XMPP: URI

  - by Coderer

  I found out how to link directly to a chat room on a Jabber conference server -- it took a bit of digging, and I wound up actually looking at the spec before I was sure I was doing it right. I confirmed here, so I'm pretty sure I've got it. The results, though, are puzzling. If I click a link of the style xmpp:[email protected] I get a new chat session with user "dude" at example.com, as expected. If I tack on a nonsense query (xmpp:[email protected]?foobar), it's ignored, which is what the spec says should happen. However, if I use xmpp:[email protected]?join, as in the link above, nothing happens. I dug a little deeper, and found out that on my (Linux) system, xmpp URIs are handled via purple-url-handler, so I dropped to a terminal and ran it manually. The result was that any xmpp URI ran fine except one that includes a ?join query. The ?join query results in a dbus crash, pointing specifically to line 2356 of dbus-message.c -- a little Googling suggests this probably is dbus's less-than-elegant way of telling me that somebody is using dbus incorrectly. Am I crafting my link correctly? Is this an OS or maybe application issue? Does this work on other platforms / browsers / etc? More importantly, is there any easy way to fix it?

• How can I have puppet deploy ssh keys for virtual users?

  - by Pheezy

  I am trying to get puppet to assign authorized ssh keys for virtual users but I keep getting the following error: err: Could not retrieve catalog: Could not parse for environment production: Syntax error at 'user'; expected '}' at /etc/puppet/modules/users/manifests/ssh_authorized_keys.pp:9 I believe my configuration are correct (listed below) but is there a syntax error or scoping issue I am missing? I would simply like to assign users to nodes and have those users automagically have their ssh keys installed. Is there maybe a better way to do this and I'm just overthinking it? # /etc/puppet/modules/users/virtual.pp class user::virtual { @user { "user": home => "/home/user", ensure => "present", groups => ["root","wheel"], uid => "8001", password => "SCRAMBLED", comment => "User", shell => "/bin/bash", managehome => "true", } # /etc/puppet/modules/users/manifests/ssh_authorized_keys.pp ssh_authorized_key { "user": ensure => "present", type => "ssh-dss", key => "AAAAB....", user => "user", } # /etc/puppet/modules/users/init.pp import "users.pp" import "ssh_authorized_keys.pp" class user::ops inherits user::virtual { realize( User["user"], ) } # /etc/puppet/manifests/modules.pp import "sudo" import "users" # /etc/puppet/manifests/nodes.pp node basenode { include sudo } node 'testbox' inherits basenode { include user::ops } # /etc/puppet/manifests/site.pp import "modules" import "nodes" # The filebucket option allows for file backups to the server filebucket { main: server => 'puppet' } # Set global defaults - including backing up all files to the main filebucket and adds a global path File { backup => main } Exec { path => "/usr/bin:/usr/sbin/:/bin:/sbin" }

• Switching from prefork MPM to worker MPM + php-fpm on ubuntu

  - by Shane

  All tutorials I found were how to fresh install worker MPM + PHP-FPM, since my wordpress blog's already up and running with prefork MPM, correct me if I'm wrong in the simulated installation process: I'm on ubuntu and according to some tutorials, the following lines would do all the tricks: apt-get install apache2-mpm-worker libapache2-mod-fastcgi php5-fpm php5-gd a2enmod actions fastcgi alias Then you setup configuration in /etc/apache2/conf.d/php5-fpm.conf: <IfModule mod_fastcgi.c> AddHandler php5-fcgi .php Action php5-fcgi /php5-fcgi Alias /php5-fcgi /usr/lib/cgi-bin/php5-fcgi FastCgiExternalServer /usr/lib/cgi-bin/php5-fcgi -host 127.0.0.1:9000 -pass-header Authorization </IfModule> After all these, restart: service apache2 restart && service php5-fpm restart Question: 1) Would it cause any down time in the whole process for previously running sites with prefork MPM? 2) Do you have to change any already existent configuration files like php or mysql or apache2(would they take effect immediately after the switch without you doing anything)? 3) I've already have apc up and running, do you have to re-install/re-configure it after the switch? 4) How do you find out if apache2 is working in worker MPM mode as expected? Thanks a lot!

• cpu load measure with hyperthreading on linux

  - by dronus

  How can I get the true usage of a multicore hyperthreading enabled cpu? For example lets consider a 2 core CPU, expressing 4 virtual cores. A single threaded workload would now show up as 100% in top, as one core of the virtual cores is completely used. The CPU and top work as expected, like there would be 4 real cores. With two threads however, the things get arkward: If all works well, they are balanced to the two real cores, so we got 200% usage: Two times 100% and two idle virtual cores, and are using all of the available CPU power. Seems ok to me. However, if the two threads would run on a single real core, they would show up as using two times 100%, that makes 200% virtual core usage. But on the real side, that would be one core sharing its power on the two threads, which are then using only one half of the total CPU power. So the usage numbers shown by top can not be used to measure the total CPU workload. I also wonder how hyperthreading balances two virtual on a real core. If two threads take a different amount of cycles, would the virtual cores 'adapt' so that both show a 100% load even if the real load differ?

• Determining a realistic measure of requests per second for a web server

  - by Don

  I'm setting up a nginx stack and optimizing the configuration before going live. Running ab to stress test the machine, I was disappointed to see things topping out at 150 requests per second with a significant number of requests taking 1 second to return. Oddly, the machine itself wasn't even breathing hard. I finally thought to ping the box and saw ping times around 100-125 ms. (The machine, to my surprise, is across the country). So, it seems like network latency is dominating my testing. Running the same tests from a machine on the same network as the server (ping times < 1ms) and I see 5000 requests per second, which is more in-line with what I expected from the machine. But this got me thinking: How do I determine and report a "realistic" measure of requests per second for a web server? You always see claims about performance, but shouldn't network latency be taken into consideration? Sure I can serve 5000 request per second to a machine next to the server, but not to a machine across the country. If I have a lot of slow connections, they will eventually impact my server's performance, right? Or am I thinking about this all wrong? Forgive me if this is network engineering 101 stuff. I'm a developer by trade. Update: Edited for clarity.

• Which database to use and system/db administration by layman [closed]

  - by blah

  So my friend and I got briliant ;) idea for a business. Since it is not predictable whether it will work out or not, we decided to keep cost as low as possible to start with, in particular not to hire anyone. If it will work out as expected it will generate enough profit to hire professionals in few months. But for the first few months we'll be doing everything by ourselfs. He's a business/finance major, and I'm a software developer, so obviously I have to take care of IT :) It will be a webapp, written in python/django. My questions regarding this project: 1) What database should I choose? I'm experienced with oracle, and have been working with SQL Server for a while, but both of them are too expensive(at least now). It's a developer experience, I've never done any dba stuff. I'm looking for something free(as in beer). Looks like MySql or PostgreSQL are most popular in this sector. I would appreciate any comments on which db to choose. I'm open to any suggestions(it doesn't have to be MySql or Postgre). Here's what I know about data: It will be almost dates and numbers, a little bit of text. Searched mainly by dates. Data will almost never be updated, mostly inserted and browsed. From 30k to 300k new records/month. 2) Servers. My idea is to rent two dedicated servers. During normal operation one would be a web server(debian/apache), other would be a db server(debian/?). My recovery plan is to install everything on both, and in case of trouble with one of machines just run everything on the other one. Does it even makes sense? Any other tips appreciated. Thanks.

• How do I get netcat to accept connections from outside the LAN?

  - by Chris

  I'm using netcat as a backend to shovel data back and forth for a program I'm making. I tested my program on the local network, and once it worked I thought it would be a matter of simply forwarding a port from my router to have my program work over the internet. Alas! This seems not to be the case. If I start netcat listening on port 6666 with: nc -vv -l -p 6666, then go to 127.0.0.1:6666 in a browser, as expected I see a HTTP GET request come through netcat (and my browser sits waiting in vain). If I go to my.external.ip.address:6666, however, nothing comes through at all and the browser displays 'could not connect to my.external.ip.address:6666'. I know that the port is correctly forwarded, as www.canyouseeme.org says port 6666 is open (and when netcat is not listening, that its closed). If I run netcat with -g my.adslmodem's.local.address to set the gateway address, I get the same behavior. Am I using this command line option correctly? Any insight as to what I'm doing wrong?

• Unzipping archives, preserving folder hierarchy

  - by Hydrangea

  I've got a problem and am not sure what it is, but hope someone can help me think this through because this has me stumped. Backstory: I wrote a Java app (Android) that unzips some zip files downloaded from the network. Until now, this was working great. Then, this week, the archives that I'm creating on my pc (in Ubuntu 12.04) unzip on the Android phone into a flat hierarchy instead of preserving the folders. I'm creating the archives the same way (right-click on folder compress) but even though my old archives (created in 10.04) still unzip as expected, the new ones don't. On Ubuntu, the new zip files look the same to me as the old ones. When unzipped on my pc the folders in these new archives are restored the same as the old ones... it's the Android app that extracts the old ones fine and the new ones flat. What I really want to know, though, is what the difference between the archives is. Question: How could one determine why one zip archive would be extracted with folder hierarchy preserved, when an identical one (to all appearances on Ubuntu 12.04) is extracted with no hierarchy? Are there different ways in which a .zip file can "have" folders, but Ubuntu doesn't distinguish between them?

• vCenter 5.1 SSO Configuration option not available in Web Client?

  - by goober

  Problem I just finished separately installing vCenter Server 5.1. I installed the components separately but on the same machine using a local SQL 2008 R2 DB (not SQL express). Everything appears to be working correctly with the exception of SSO. It doesn't find the AD server. This is to be expected (see below) but I don't know how to fix it. Potential Leads / Steps taken During the install of SSO, I was logged on as a local administrator (waiting on central IT dept to create a service account). As a result, I received a message saying that SSO wouldn't be able to automatically locate the AD. (fair eonugh) After I read up on it a little bit, I believed I could go into the SSO Configuration option in the Web client, like so: However, what I actually see is: I also notice that the "SSO Users and Groups" entry is not there. Betting that has something to do with it as well. Question How can I get the "Configure" Option to show up for SSO? Overall goal: How can I manually enter the AD server in this scenario while logged in as a local administrator? References VMWare vCenter 5.1 Installation: Part 9 (Optional SSO Configuration) [Derek Seaman's Blog] (used the image of correct configuration menu)

• Conky starts above windows in Ubuntu Maverick

  - by DesertIvy

  Hey guys, I did not run into this problem until I upgraded my Ubuntu box to Maverick Meerkat (10.10). Basically, whenever I start my computer, conky runs as expected, except it gets drawn over any windows that I load (see screenshot). To fix this for a single session, I simply restart conky by running killall conky; conky in a terminal. Conky gets re-drawn below active windows (namely, only appearing on my desktop), and does not have the border/drop-shadow, but I have to do this every time I start a new session. Is there a simple way to fix this? I have a small shell script that I run on startup, but it does not seem to solve the problem. #!/bin/bash sleep 10 && conky; sleep 5 && killall conky; conky; Below is the non-text part of my .conkyrc file. # Conky settings # background yes update_interval 1 cpu_avg_samples 2 net_avg_samples 2 override_utf8_locale yes double_buffer yes no_buffers yes text_buffer_size 2048 #imlib_cache_size 0 temperature_unit fahrenheit # Window specifications # own_window yes own_window_type override own_window_transparent yes own_window_hints undecorate,sticky,skip_taskbar,skip_pager,below border_inner_margin 0 border_outer_margin 0 minimum_size 200 250 maximum_width 200 alignment tr gap_x 220 gap_y 280 # Graphics settings # draw_shades no draw_outline no draw_borders no draw_graph_borders no # Text settings # use_xft yes xftfont caviar dreams:size=8 xftalpha 0.5 uppercase no temperature_unit celsius default_color FFFFFF # Lua Load # lua_load ~/.lua/scripts/clock_rings.lua lua_draw_hook_pre clock_rings

• Bounce backs from web-generated e-mails are missing

  - by JerSchneid

  We use Google Apps to host my company's mail. On our website, we send some e-mails on behalf of our users. In those e-mails we include lines like this: Return-Path: <[email protected]> Sender: <[email protected]> Sending the messages works great (passes SPF tests), but in the case that the message is sent TO an invalid e-mail address, we expect to get a bounce back message sent to "[email protected]". That message never arrives. (If we send an e-mail manually from within the gmail interface to the same bad e-mail, the message does arrive). We used to receive the bounce back messages as expected, but it seems like they are always quietly blocked now (not in spam or anything). Is there a new policy that blocks bounce backs when the "From" does not match the "Return-Path" or something? We would really like to get these bounce-backs to verify the delivery of the messages. Is there any way to prevent them from being blocked?! Thank you!

• iptables: allowing incoming for 192.168.1.0/24 allowed incoming for all?

  - by nortally

  The internal side of my ISP router has three devices: ISP router 128.128.43.1 Firewall router 128.128.43.2 Server 128.128.43.3 Behind the Firewall router is a NAT network using 192.168.100.n/24 This question is regarding iptables running on the Server. I wanted to allow access to port 8080 only from the NAT clients behind the Firewall router, so I used this rule -A Firewall-1-INPUT -s 192.168.100.0/24 -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPT This worked, but UNEXPECTEDLY ALLOWED GLOBAL ACCESS, which resulted in our JBOSS server getting compromised. I now know that the correct rule is to use the Firewall router's address instead of the internal network, but can anyone explain why the first rule allowed global access? I would have expected it to just fail.

• Is there a way to use something similar to a capture group for apache2 server name

  - by Zipper

  I have a server that sits behind an AWS load balancer. The LB can't do automatic redirect from HTTP to HTTPs, and the LB is doing my SSL. So I need to setup apache on my servers to redirect any request on port 80 to https://FOOBAR m where FOOBAR is the domain that came in. I haven't been able to find a way of doing that so far. I'm an apache newb though. What I'm trying to do is something similar to this. I'll use regex as an example <VirtualHost *:80> ServerName (.*) Redirect / https://\1 </VirtualHost> If there's a better way to do this, please let me know. EDIT: Sorry I should have explained why this is happening. I actually have a tomcat server running my app on port 8080, and the LB points to that. From what I can tell so far my requests come in on http (which is expected), but when my app server sends redirects (for login purposes) it tries to redirect to http, instead of https. I haven't had a chance to fully investigate this, but I wanted to work around it for now by point the LB to point to the apache server, and have any port 80 requests redirect to 443. EDIT2: The other reason I'm interested in doing this, is that since the LB can't do the redirect, I need to have another redirect mechanism in place to tell the browser to go to https://FOOBAR

• Unknown user in terminal

  - by Giles B

  Im having a strange problem with the terminal in OS X. When I open the terminal the username at the command prompt is: unknown-04-0c-ce-e3-0d-c2: ~ I can't pinpoint when this first started or why unfortunately. I usually use iTerm for web development purposes but this also occurs in the normal OS X Terminal app. Any ideas/help would be really appreciated. Thanks Update: Thanks to @fayadfami and @aliasgar for the correct answers and steering me in the right direction. Also this forum post helped http://forums.macrumors.com/showthread.php?t=152407 The extract from the right post: Having run into the exact same issue myself, and having come across this thread while attempting to figure it out, I thought I'd post the answer. OS X is initially setting your hostname to what's set for your Computer Name in Sharing; however, if you're set up for DHCP and you match a current lease on your DHCP server (i.e., match the IP address of another recent user), OS X will then set your hostname to whatever the DHCP server currently has for that lease. This freaked me out incredibly at first, as I had just reformatted (having just purchased my first Mac and wanting to see how the installer worked) and knew I had not yet changed the Computer Name in Sharing -- yet my system hostname at the Terminal prompt was indeed changed to what I had previously set, pre-format. I grepped around, not finding the name anywhere save log entries; I thought either the format didn't actually properly wipe everything, or I was losing my mind. Finally I logged into my router (it's a Linksys WRT54GS running OpenWRT), and found the hostname in the current leases file. I then manually set my Mac's IP to something different, and volia! -- the hostname was back to what I expected. I hope this helps save someone from the same paranoia I went through.

• Debian network bridge configuration - /etc/network/interfaces

  - by Mathias

  I'm running a Lenny Xen dom0 hosting multiple virtual machines in a routed IP setup. To get an additional private subnet, I created the bridge xenbr0 in the dom0 with the following commands: brctl addbr xenbr0 ifconfig xenbr0 10.0.0.1 netmask 255.255.255.0 ifconfig xenbr0 up This works as expected, and domU interfaces are added to the bridge by Xen on VM start. My only problem is: how the heck do i specify this configuration in /etc/network/interfaces that it remains permanent and the bridge is available after a reboot? I tried the following config as found on a lot of tutorials: auto xenbr0 iface xenbr0 inet static address 10.0.0.1 netmask 255.255.255.0 network 10.0.0.0 broadcast 10.0.0.255 bridge_stp no I get 2 different errors, depending on if the bridge already exists or not. If it doesn't exist: root@dom0:~# brctl show bridge name bridge id STP enabled interfaces root@dom0:~# /etc/init.d/networking restart Reconfiguring network interfaces...if-up.d/mountnfs[eth0]: waiting for interface xenbr0 before doing NFS mounts (warning). SIOCSIFADDR: No such device xenbr0: ERROR while getting interface flags: No such device SIOCSIFNETMASK: No such device SIOCSIFBRDADDR: No such device xenbr0: ERROR while getting interface flags: No such device xenbr0: ERROR while getting interface flags: No such device Failed to bring up xenbr0. done.

RTNETLINK answers: File exists Failed to bring up xenbr0. done. Could anyone point me in the right direction please? The bridge works fine when created manually, i just need the right config file entries. The most tutorials I found add some devices to the bridge in the config, is that maybe the problem why it is not working? I don't have any interfaces I want to add to the bridge on creation as they get added later on VM start... Thanks, Mathias

• Windows 8 - no internet connetction to some hosts while VPN is active

  - by HTD

  I use VPN to access the servers at work. When VPN is used, all network traffic to the Internet passes through my company network. It worked without any problems on Windows 7, now on Windows 8 some sites suddenly became inaccessible. Please note - I don't try to connect them over RDP, they are public Internet addresses, outside company network. They are inaccessible using any protocol. Ping returns "General failure.". I know it could be a misconfiguration on my company's server side, but it's very strange, since the same VPN connection used on Windows 7 works properly. What's wrong? Is it a Windows 8 bug, or is there something I could do on my company servers to make VPN work as expected with Windows 8? My company network works on Windows Server 2008 R2 and uses Microsoft TMG firewall. I couldn't find any rules blocking the traffic to mentioned sites, all network traffic for VPN users are passed through for all IPs and protocols. Any clues? UDPATE: Important - one whole day it worked. I hibernated and restarted the computer, connected and disconnected VPN - nothing could break my connection. Today it broke again, and restarting Windows didn't help. And now the solution: route add -p 0.0.0.0 MASK 255.255.255.255 192.168.1.1 Oh, OK, I know what it did, added my default gateway to routing table. But it still didn't work sometimes. So I removed my main network gateway route with: route delete -p 0.0.0.0 MASK 0.0.0.0 192.168.0.1 And added modified with: route add -p 0.0.0.0 MASK 255.255.255.255 192.168.0.1 And it works. Now. But I don't trust this. I don't know what really happened.

• VMware Workstation reboot 32-bit host when starting 64-bit guest

  - by Powerman

  I'm trying to start 64-bit guest (MacOSX and Windows7) on 32-bit host (Hardened Gentoo Linux, kernel 2.6.28-hardened-r9) using VMware Workstation (6.5.3.185404 and 7.0.1.227600). If VT-X disabled in BIOS, VMware refuse to start 64-bit guest (as expected). If VT-X enabled in BIOS, VMware start guest without complaining, but then, in about a second (I suppose as soon as guest try to switch on 64-bit) my host reboots (actually, it's more like reset - normal reboot procedure skipped and BIOS POST start immediately). My hardware is Core 2 Duo 6600 on ASUS P5B-Deluxe with latest stable BIOS 1101. I've power-cycled system, then enabled Vanderpool in BIOS. My CPU doesn't support Trusted Execution Technology, and there no way to disable it in BIOS. I've rebooted several times after that, sometimes with power-cycled, and ensure Vandertool is enabled in BIOS. I've also run VMware-guest64check-5.5.0-18463 tool, and it report "This host is capable of running a 64-bit guest operating system under this VMware product.". About a year ago I tried to disable hardened in kernel to ensure this isn't because of PaX/GrSecurity, but that doesn't help. I have not checked 32-bit guests with VT-X enabled yet, but without VT-X they works ok. ASUS provide "beta" BIOS updates, but according to their descriptions these updates doesn't fix this issue, so I'm not sure is it good idea to try it. My best guess now it's motherboard/BIOS bug. Any ideas?

• XP Client for NFS failure dialog on startup, but drive mapping works

  - by Matt Bennett

  I'm mounting an NFS share to some windows machines using the tools that come in the Services for UNIX Administration toolkit. I've set up the User Name Mapping service to use local passwd and group files. I had to manually start the User Name Mapping service, and then created an 'advanced map' from the XP machine's user to a uid that exists in on my NFS server, like so: Windows User: Matt Bennett UNIX Domain: PCNFS UNIX User: mattbennett UID: 10250 Primary: * I can map a network drive without any issues, and it correctly identifies the UID and GID to use, but when I reboot I get this message: "An error occurred while connecting to the NFS server. Make sure that the Client for NFS service has started. If the problem persists make sure Client for NFS service can communicate with User Name Mapping or PCNFS server." After dismissing the dialog, the machine finishes booting and the network drive is there in My Computer with the title "Disconnected Network Drive", but I can open it I can see the network share without a problem, and then it drops the 'disconnected' from its title. It seems like the services are starting in the wrong order or something, so the first attempt to connect fails but subsequent ones work as expected. There don't seem to be any symptoms apart from the dialog box, but obviously something's not quite right. What have I done wrong? Thanks, Matt.

• What does a DHCP-client consider to be the "best" answer?

  - by Nils

  We have training rooms where normally Windows XP is installed (via PXE). The "normal" DNS/DHCP infrastructure are Windows-Servers. The training room has its own VLAN (different from the Windows servers), so there is most propably an IP helper for DHCP requests active on the Cisco router where all PCs from that room are connected to. Now we wanted to convert some of the PCs to Linux instead. The idea was: Put our own Laptop with a DHCP server into the VLAN of the room and override the "normal" DHCP response. The idea was that this should work, since a directly attached DHCP server in that VLAN should have a faster response-time than the "normal" DHCP server located some hops away from that VLAN. It turned out that this did not work. We had to manually release the lease on the original DHCP server to get it working. On the Laptop we did see the client requesting the IP and "our" dhcp was sending NACKs to the Windows IP request, before that we did offer our own response. Old Question: Why did this not work out as expected? What is making the PC regain its old lease? Update 2012-08-08: The regain-issue has been explained in the DHCP-RFC. Now this explains why the PC regains its old lease. Now we do release the IP from the Windows-DHCP-server before giving it another try. Again - the Windows-DHCP-server wins. I suspect that there is some algorithm for the dhcp-client which determines the "best" dhcp-answer for the client. The new question is: How does the client choose the "best" answer?

• IIS6 intranet site using integrated authentication fails to load when accessed externally

  - by maik

  I've developed a couple of internal sites for my organization that use integrated authentication. Ultimately we want these sites to be accessible externally to users with domain-joined computers. The sites work as expected on domain computers while on the internal network. The problem comes when I take my laptop home and try to access those sites. IIS only has integrated authentication enabled for the two sites. When I browse to the site using IE8 I get a username/password prompt asking for domain credentials. I can put those in and it will work, but the goal is to use the cached token for integrated authentication. Next I reasoned that IE wouldn't response to an integrated auth request (is NTLM the right term for this?) unless the site was trusted. I tried adding the site to Trusted Sites but I get the same behavior as the before. I then added the site to Local Intranet sites and that is where things get weird. I get a generic error page from IE, no error code or anything. Just for funsies I loaded up Firefox (which I had previously set up to use integrated authentication) and I added this new site to network.automatic-ntlm-auth.trusted-uris. Much to my surprise I was able to load the pages up with no problem at all and saw exactly what I was expecting (including verification that the integrated authentication worked). My mind is a bit boggled at the moment as I'm not really sure where to go from here. I was hoping some of you may be able to provide some insight.

• Linux Scheduler (not using all cores on multi-core machine) RHEL6

  - by User512

  I'm seeing strange behavior on one of my servers (running RHEL 6). There seems to be something wrong with the scheduler. Here's the test program I'm using: #include <stdio.h> #include <unistd.h> #include <stdlib.h> void RunClient(int i) { printf("Starting client %d\n", i); while (true) { } } int main(int argc, char** argv) { for (int i = 0; i < 4; ++i) { pid_t p_id = fork(); if (p_id == -1) { perror("fork"); } else if (p_id == 0) { RunClient(i); exit(0); } } return 0; } This machine has a lot more than 4 cores so we'd expect all processes to be running at 100%. When I check on top, the cpu usage varies. Sometimes it's split (100%, 33%, 33%, 33%), other times it's split (100%, 100%, 50%, 50%). When I try this test on another server of ours (running RHEL 5), there are no issues (it's 100%, 100%, 100%, 100%) as expected. What's causing this and how can I fix it? Thanks
