• How do I create an MBR on a USB stick using DD command line tool

  - by Lana Miller

  Okay I'm trying to create a BOOTABLE Windows7 image on a USB key from a Mac running Lion. My image is .iso format. I tried: sudo dd if=/Users/myusername/Win7.iso of=/dev/disk1 bs=1m And this succeeded in writing the files, except in DISK UTILITY on the mac, it shows the partition type as GUID Partition Table and not 'Master Boor Record'. Booting the key on my Vista computer yields the error "No boot sector on USB Device' From what I can tell, bs=1m in the DD command should have left 1 Megabyte for the boot sector, but for some reason this area of the USB Key is not set up correctly so that it will boot How can I fix this, or correctly use dd to write a bootable cd image such that it is now a bootable usb drive? Note: in the instructions I read about, they recommended renaming my Win7.iso to Win7.dmg before using DD, which made absolutely no sense to me, so I didn't do it. I could try with that step now, but it takes 1.99 hours to write the image to the USB drive so there is a huge penalty to trial and error here. Thank you.

• Relation between server_name in nginx sites-available, /etc/hosts file and A-records

  - by user2818584

  I have the following two server-blocks in my config-file in sites-available: server { listen 80; server_name www.mydomain.be; root /usr/share/nginx/html; index index.html index.htm; location / { try_files $uri $uri/ =404; } } server { listen 80; server_name sub.mydomain.be; root /usr/share/nginx/sub; index index.html index.htm; location / { try_files $uri $uri/ =404; } } I also created an A-record for both www.domain.be and sub.domain.be with the IP of my server as value. Yet, when I try to reload my nginx configuration with service nginx reload it fails. When I remove the second server-block, it reloads as expected. I know this topic is popular, and that there are loads of such [nginx][subdomain] questions here, but none of them seems to discuss explicitly how the following three things hang together: virtual hosts or server blocks in nginx (est. server_name matching) the effect of A-records on how nginx processes requests the need to add hosts to /etc/hosts Right now I have the impression that a lack of knowledge of this bigger picture, rather than specific knowledge of nginx configuration prevents me from making this work.

• Per connection bandwidth limit

  - by Kyr

  Apparently, our server box running Windows Server 2008 R2 has a per connection bandwidth limit of 0.2 MB/s. Meaning, while one TCP connection can pull at max 0.2 MB/s, 60 parallel connections can pull 12 MB/s. We first noticed this when trying to checkout large SVN repository from this server. I used a simple Java application to test this, transferring data from server to workstation using variable number of threads (one connection per thread). Server part of the application simply writes 1 MB memory buffer to socket 100 times, so there is no disk involvement. Each connection topped at 0.2 MB/s. Same per connection limit was for only one as was for 60 parallel connections. The problem is that I have no idea from where this limit comes from. I have very little experience administrating Windows Server, so I was mostly trying to find something by googling. I have checked the following: Local Computer Policy QoS Packet Scheduler Limit reservable bandwidth: it's Not configured; Group Policy Management Console: we have two GOPs, but neiher has any Policy-based QoS defined; There isn't any bandwidth limiter program installed, as far as I can tell. We're using standard Windows Firewall. I can update this question with any additional information if needed.

• how to back up data from a machine that keeps hanging

  - by Amit Phatarphekar

  Hello - I have a storage server running opensolaris. But lately its been acting up - it hangs at random times due to some SCSI/ATA related error messages. I've tried to fix it without any progress, so I'm giving up now. The machine keeps hanging every 30 minutes or 1 hr ...sometimes after 4 hrs. Its very unpredictable. So I've decided to just reformat the storage server and start from scratch...maybe I'll just not use solaris and install something else, since the errors are related to solaris running on ATA HDD or something. Question - Before I reformat it, I want to back up some of the important data on it. Like it has a VM with 200 GB disk files, it has a whole bunch of ISOs stored on it etc etc. I'm using a simple scp to copy the files over to a different machine. My issue is that, because the machine hangs....sometimes my file copy is incomplete and I have to start all over again. Lets say I'm trying to copy a 200GB file which takes like 4 hrs....IF the machine hangs before the whole file i copied over...I have to recopy the file from scratch. Is there a solution to copy the files over such that if the machine hangs or network goes down..the copying can resume from where it left off? - like if 50 GB of a 200GB file was copied and machine hung....next time, it'll just continue to copy rest of the amount, instead of starting all over again. Thanks Amit

• HP G61 Laptop wont boot- display stays off, caps and num lock indicators blink repeatedly

  - by Benguy12

  I had my HP G61 laptop running in sleep for a while. When I came back to it about a half-hour later, it was no longer in sleep mode - the power light and the Wi-Fi indicator light were on (I keep Wi-Fi off becuase I use a wired connection) - but nothing was showing on screen. In fact, the display wasn't even turned on. So I let it sit for about 10 minutes but nothing happened. I did a force shut down and rebooted. Instead of a normal boot, the display didnt turn on, the Wi-Fi indicator was off, and the Caps Lock and Num Lock lights just blinked repeatedly. On the external keyboard i use, none of the light indicators were blinking or even on. I tried force shut-down again 10 times, then unplugged all connections except for the power cable (my laptop battery dosent hold a charge for more than 2 minutes, so I always must have a wall connection) and tried to boot again but still nothing happened. I unplugged the battery and even then nothing happened. I also tried booting with the disk drive open, and then with it closed again. On the time it was closed, I was able to successfully boot into Windows, but recieved a "Windows did not shut-down sucessfully" notice. Does anybody know why this may have happened? My PC's specs: Windows 7 Home Premium, 64-bit 4GB of physical RAM, 8GB of vRAM (on a flash drive) AMD Vision x64 processor (don't know any other specs about it) ATI Radeon graphics card, 392 MB DVD-R/W lightscribe drive 2 External hard-disks (first one is 1.5TB, second one is 1TB) custom boot-screen and boot-annimation Standard BIOS apps running before sleep: firefox 10.4 itunes 10.6 adobe photoshop extended CS5.1 rockstar games social club (running in background) microsoft powerpoint 2010 professional edition google chrome I was NOT running Aero or any fancy themes - I was using the normal windows classic theme. I have a desktop icon manager application called Stardock Fences that was also running (it runs as a service/process).

• Microsoft Application Request Routing with Windows Authentication

  - by theplatz

  I'm running into a problem trying to get Windows Authentication working in an environment that uses Microsoft Application Request Routing and was hoping someone might be able to help. The problem I'm running into is that only some requests are authenticated, while others fail with 401 errors. I have followed the Special Case of Running IIS 7.0 in a Web Farm instructions found at http://blogs.msdn.com/b/webtopics/archive/2009/01/19/service-principal-name-spn-checklist-for-kerberos-authentication-with-iis-7-0.aspx to no avail. My current server setup looks like the following: ARR Two servers set up with IIS shared configuration using IIS 7.5 on Windows 2008 R2 Anonymous authentication turned on for the Default Web Site Web Farm Two servers running IIS 7.5 on Windows 2008 R2 Three web sites set up using port binding to differentiate between virtual hosts. Ports being used are 8000, 8001, and 8002 Application pools for Windows Authentication all use a common domain account SPN added to domain account for http/<virthalhost-name>:<port-number> and http/<virtualhost-name>.<fully-qualified-domain>:<port-number> The IIS logs show the following when authentication is working/failing.

• chkconfig creating service symlinks with the wrong order

  - by Robert

  On RHEL 6.3, I have a system service that should be starting after postgresql and httpd (order 64 and 85, respectively), but chkconfig always places it at order 50. I tried an experiment on a CentOS 6.0 virtual machine to make sure I understood the LSB stanza syntax. I created /etc/init.d/foo, owner root, permissions 755, with this text: ### BEGIN INIT INFO # Provides: foo # Required-Start: postgresql httpd # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 # Description: Foo init script ### END INIT INFO And then ran chkconfig --add foo. Result: /etc/rc5.d/S86foo is created, as expected. (The other runlevels are also as expected.) I repeated the exact same experiment on the RHEL machine, and it created /etc/rc5.d/S50foo instead. I can't see anything different between the two that would lead to different results. Both machines have postgresql and httpd starting at the same orders and runlevels. Any thoughts? I could just use # chkconfig: 2345 86 50, or manually rename the service symlinks to the correct order, but I'm trying to document an install process for later users, and I want to know how to do it right and understand why it's not working as expected.

• Tidy up old Windows Server Backup snapshots

  - by dty

  Hi, I'm running wbadmin from a scheduled job, backing up my C: and D: drives to my E: and (I believe!) including the system state: wbadmin start backup -backuptarget:e: -include:c:,d: -allCritical -noVerify -quiet I'd like to delete old backups, but I'm concerned that all the information I can find says to use wbadmin to delete old system state backups, and vssadmin to delete other backups. As far as I know, my backups ARE system state backups, but are using VSS on E: for storage, so I'm worried about trying either of these techniques for fear of losing all my backups. This is a home network, so I don't have a spare server to test this on. I'm also happy to simply restrict the space used on E:, but I can't make sense of the difference between the /for and /on parameters of the relevant vssadmin command. For reference, here's the output of vssadmin show shadows: Contents of shadow copy set ID: {xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx} Contained 1 shadow copies at creation time: 07/01/2011 08:12:05 Shadow Copy ID: {xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx} Original Volume: (E:)\\?\Volume{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}\ Shadow Copy Volume: \\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy83 Originating Machine: x.y.com Service Machine: x.y.com Provider: 'Microsoft Software Shadow Copy provider 1.0' Type: DataVolumeRollback Attributes: Persistent, No auto release, No writers, Differential [... repeated a lot...] vssadmin show shadowstorage: Shadow Copy Storage association For volume: (C:)\\?\Volume{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}\ Shadow Copy Storage volume: (C:)\\?\Volume{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}\ Used Shadow Copy Storage space: 0 B Allocated Shadow Copy Storage space: 0 B Maximum Shadow Copy Storage space: 5.859 GB Shadow Copy Storage association For volume: (D:)\\?\Volume{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}\ Shadow Copy Storage volume: (D:)\\?\Volume{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}\ Used Shadow Copy Storage space: 0 B Allocated Shadow Copy Storage space: 0 B Maximum Shadow Copy Storage space: 40.317 GB Shadow Copy Storage association For volume: (E:)\\?\Volume{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}\ Shadow Copy Storage volume: (E:)\\?\Volume{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}\ Used Shadow Copy Storage space: 168.284 GB Allocated Shadow Copy Storage space: 171.15 GB Maximum Shadow Copy Storage space: UNBOUNDED wbadmin get versions: Backup time: 07/01/2011 03:00 Backup target: 1394/USB Disk labeled xxxxxxxxx(E:) Version identifier: 01/07/2011-03:00 Can Recover: Volume(s), File(s), Application(s), Bare Metal Recovery, System State [... repeated a lot...]

• Connection refused in ssh tunnel to apache forward proxy setup

  - by arkascha

  I am trying to setup a private forward proxy in a small server. I mean to use it during a conference to tunnel my internet access through an ssh tunnel to the proxy server. So I created a virtual host inside apache-2.2 running the proxy, the proxy_http and the proxy_connect module. I use this configuration: <VirtualHost localhost:8080> ServerAdmin xxxxxxxxxxxxxxxxxxxx ServerName yyyyyyyyyyyyyyyyyyyy ErrorLog /var/log/apache2/proxy-error_log CustomLog /var/log/apache2/proxy-access_log combined <IfModule mod_proxy.c> ProxyRequests On <Proxy *> # deny access to all IP addresses except localhost Order deny,allow Deny from all Allow from 127.0.0.1 </Proxy> # The following is my preference. Your mileage may vary. ProxyVia Block ## allow SSL proxy AllowCONNECT 443 </IfModule> </VirtualHost> After restarting apache I create a tunnel from client to server: #> ssh -L8080:localhost:8080 <server address> and try to access the internet through that tunnel: #> links -http-proxy localhost:8080 http://www.linux.org I would expect to see the requested page. Instead a get a "connection refused" error. In the shell holding open the ssh tunnel I get this: channel 3: open failed: connect failed: Connection refused Anyone got an idea why this connection is refused ?

• Scriptable BitTorrent clients?

  - by James McMahon

  In an effort further automate all the little computer house keeping tasks that can waste my time I am looking into BitTorrent clients that have the ability to script common tasks. I've done some Googling and it looks like Transmission might have some of said such capabilities, but there site wasn't very clear on the details. Things I am looking to do; Prioritize and label torrents based on trackers Set seed length based on trackers and filesize Set additional seed time when a torrent's seed time expires based on a number of factors, like time spent seeding, remaining disk space and ratio. Move torrents to appropriate places post seeding based on labels and tracker Basically, while I could Python or Bash script things like moving torrents around and other simple actions, I need away to talk to the client to figure out things like the torrent seed time, tracker, labels, filesize, etc. Is there any client out there that would allow me to all or a subset these actions? I have access to Linux, Mac and Windows and am not tied to any particular torrent client. I am a programmer so I have no problems writing scripts, but examples of torrent scripting would also be helpful.

• Sony PMB causing failure to load Windows 7 Pro 64-bit normally or even Safe Mode

  - by Wesley

  After installing Sony's Picture Motion Browser on my desktop with Windows 7 Pro x64, it always goes to Startup Repair due to Windows 7 failing to start. This always happens after I try to install it. I've installed with all unnecessary programs closed and all disk drives and unnecessary usb ports empty. I don't exactly know what is causing the problem. Any ideas? My desktop is an HP m8530f. http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01469325&tmp_task=prodinfoCategory&lc=en&dlc=en&cc=us&product=3740333&lang=en Only upgrades are an HD4350 and a 500W PSU. EDIT: Windows 7 cannot start now. I'm currently running diagnostic tests from the BIOS. EDIT: Here are the problem details. Problem Signature: Problem Event Name: StartupRepairOffline Problem Signature 01: 6.1.7600.16385 Problem Signature 02: 6.1.7600.16385 Problem Signature 03: unknown Problem Signature 04: 21201022 Problem Signature 05: AutoFailover Problem Signature 06: 8 Problem Signature 07: CorruptFile OS Version: 6.1.7600.2.0.0.256.1 Local ID: 1033 CONCLUSION: So, I think Sony PMB may have caused some sort of corruption in the system files. So if you have Windows 7 and plan on installing Sony PMB, find a Vista or XP machine to install on.

• How to avoid ugly dithering when running KDE over VNC?

  - by Chris Jester-Young

  I'm currently setting up a new Xen paravirt domain running KDE (4.2.2, from Kubuntu 9.04). As I have been unable to get the virtual framebuffer working in it, I've decided to set up VNC (from the vnc4server package), and run KDE over Xvnc. This is all fine and good, and KDE starts up okay. However, all the colours look dithered, especially on the task bar and title bar, making them impossible to see. From my web searches, it appears to be because these items are drawn using Porter-Duff. This is especially the case when using the Oxygen style, and Oxygen and Ozone window titlebars (selecting these styles generates messages about Porter-Duff being unavailable); not using those styles at least makes most of the UI widgets and window titles usable again. But this doesn't solve the problem for the task bar, nor for the desktop, where the only theme available to me is Oxygen (this is under the "Desktop Settings - Plasma Workspace" window, just for reference). So, unless I have a way to use a non-Porter-Duff theme for those, it seems that KDE would still be unusable under VNC. So if someone experienced with KDE can advise on how to work around, or even fix, these issues, I'd appreciate it very much. :-)

• HTTP Error: 413 Request Entity Too Large

  - by Torben Gundtofte-Bruun

  What I have: I have an iPhone app that sends HTTP POST requests (XML format) to a web service written in PHP. This is on a hosted virtual private server so I can edit httpd.conf and other files on the server, and restart Apache. The problem: The web service works perfectly as long as the request is not too large, but around 1MB is the limit. After that, the server responds with: <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>413 Request Entity Too Large</title> </head><body> <h1>Request Entity Too Large</h1> The requested resource<br />/<br /> does not allow request data with POST requests, or the amount of data provided in the request exceeds the capacity limit. </body></html> The web service writes its own log file, and I can see that small messages are processed fine. Larger messages are not logged at all so I guess that something in Apache rejects them before they even reach the web service? Things I've tried without success: (I've restarted Apache after every change. These steps are incremental.) hosting provider's web-based configuration panel: disable mod_security httpd.conf: LimitXMLRequestBody 0 and LimitRequestBody 0 httpd.conf: LimitXMLRequestBody 100000000 and LimitRequestBody 100000000 httpd.conf: SecRequestBodyLimit 100000000 At this stage, Apache's error.log contains a message: ModSecurity: Request body no files data length is larger than the configured limit (1048576) It looks like my step #4 didn't really take, which is consistent with step #1 but does not explain why mod_security appears to be active after all. What more can I try, to get the web service to receive large messages?

• What are the most important aspects to consider when choosing a SAN for a small office virtualizatio

  - by Prof. Moriarty

  I am in the process of consolidating 6 physical servers running 6 different operating system flavors (don't ask) into two identical physical servers (Dell PowerEdge 2900), using the free VMware ESXi 4.0 platform. We will install an iSCSI SAN over a 1GbE network, and store all virtual machine images on the SAN. Each physical server would run 3 VMs, and in the case of a physical server failure, we would manually switch over the other 3. These are all internal servers, while important, they can tolerate some amount of downtime (say <1h) to keep cost and complexity associated with HA down. I now need to choose the SAN to be used for the setup, on a low budget. We currently have about 2TB of data, but of course I want to able to grow, do backups of VM snapshots on other drives and remove them to a different location, etc. So what I would like to know is: Which are the must have features for this setup, without which using a SAN is not worth it? We are mostly a Dell shop, so I have been looking at the EqualLogic PS4000E High Availability model. Any opinions, anecdotes, bad experiences with this model? (This is one of the few models which could accomodate our existing disks from the physical servers.) If you can recommend something that is not Dell, but it has better value, I would most definitely consider it. Caveats, things to look out for?

• DAS vs SAN storage for serving 2 to 4 nodes

  - by Luke404

  We currently have 4 Linux nodes with local storage, arranged in two active/passive pairs with storage mirrored using DRBD, running virtual machines (actually using Xen Hypervisor) for typical hosting workloads (mail, web, a couple VPS, etc.). We're approaching the (presumed) maximum IOPS of those servers, and we're planning to migrate to an external storage solution with two active nodes, with capacity for up to four active nodes. Since we're an all-Dell shop I've done some research and found the MD3200 / MD3200i products should be the ones we're looking for. We are pretty sure we won't be attaching more than 4 hosts on a single storage and I'm wondering if there is any clear advantage for one or the other. In theory I should be able to attach 4 SAS hosts to a single MD3200 (single links on a single controller MD3200, or dual redundant SAS links from each host to a dual-controller MD3200), or 4 iSCSI hosts to a single MD3200i (directly on its 4 GigE ports without any switch, again with dual links for the dual controller option). Both setups should let us implement live VM migration since all hosts can access all the LUNs at the same time, and also some shared filesystem like GFS2 or OCFS2. Also, both setups should allow full redundancy of the whole system (assuming dual controllers in the storage). One difference I can see is that the DAS solution is actually limited to 4 hosts while the iSCSI one should be able to grow to more hosts (adding two GigE switches to the mix). One point for the iSCSI solution is that it would allow us to start out with our current nodes and upgrade them at a later time (we can't add other SAS controllers, but they already have 4 GigE ports each). With the right (iSCSI|SAS) controllers I should be able to connect diskless nodes and boot them off the external storage which I think is a good thing (get rid of any local storage). On the other hand, I would have thought the SAS one to be cheaper but it seems like an MD3200 actually costs a little less than an MD3200i (?) (please note: I've used Dell gear in my examples since that's what we're looking for but I assume the same goes with other vendors) I would like to know if my assumptions above are correct, and if I'm missing any important difference between the two setups.

• NetInstall working on some systems, not working on others

  - by cduruk

  Hi, I'm having an issue where my NetInstall setup works on some computers and fails on others. I am not able to diagnose the issue. I created an image of a Mac Mini and then created a NetRestore image using the System Image Utility found on Snow Leopard Server. NetBoot and NFS all seem to be working fine on the server, which is an XServe. Then I select the NetInstall image from the Startup Disk on a machine. On some of the machines, the process works as expected. On some of them, I see the globe icon blink a few times and then the system boots to the regular hard drive. I have captured the tracedump and the system.log logs from the server on both cases where NetInstall seems to work and fail. Here is the link that has all the logs http://gist.github.com/232232 The gist of the failure seems to be from the lack of BSDP DISCOVER in the failure but I'm not able to identify why that exactly is happening. I'd really appreciate any help on this issue.

• High load average due to high system cpu load (%sys)

  - by Nick

  We have server with high traffic website. Recently we moved from 2 x 4 core server (8 cores in /proc/cpuinfo), 32 GB RAM, running CentOS 5.x, to 2 x 4 core server (16 cores in /proc/cpuinfo), 32 GB RAM, running CentOS 6.3 Server running nginx as a proxy, mysql server and sphinx-search. Traffic is high, but mysql and sphinx-search databases are relatively small, and usually everything works blazing fast. Today server experienced load average of 100++. Looking at top and sar, we noticed that (%sys) is very high - 50 to 70%. Disk utilization was less 1%. We tried to reboot, but problem existed after the reboot. At any moment server had at least 3-4 GB free RAM. Only message shown by dmesg was "possible SYN flooding on port 80. Sending cookies.". Here is snippet of sar 11:00:01 CPU %user %nice %system %iowait %steal %idle 11:10:01 all 21.60 0.00 66.38 0.03 0.00 11.99 We know that this is traffic issue, but we do not know how to proceed future and where to check for solution. Is there a way we can find where exactly those "66.38%" are used. Any suggestions would be appreciated.

• Compiling linux kernel, how much size is needed?

  Hello, I am have downloaded the newest most stable linux kernel 2.6.33.2 I thought I would test this using virtualbox. So I create a dynamically sized harddisk of 4gb.

• ProxyPass for specific vhost with mod_rewrite

  - by Steve Robbins

  I have a web server that it set up to dynamically server different document roots for different domains <VirtualHost *:80> <IfModule mod_rewrite.c> # Stage sites :: www.[document root].server.company.com => /home/www/[document root] RewriteCond %{HTTP_HOST} ^www\.[^.]+\.server\.company\.com$ RewriteRule ^(.+) %{HTTP_HOST}$1 [C] RewriteRule ^www\.([^.]+)\.server\.company\.com(.*) /home/www/$1/$2 [L] </IfModule> </VirtualHost> This makes it so that www.foo.server.company.com will serve the document root of server.company.com:/home/www/foo/ For one of these sites, I need to add a ProxyPass, but I only want it to be applied to that one site. I tried something like <VirtualHost *:80> <Directory /home/www/foo> UseCanonicalName Off ProxyPreserveHost On ProxyRequests Off ProxyPass /services http://www-test.foo.com/services ProxyPassReverse /services http://www-test.foo.com/services </Directory> </VirtualHost> But then I get these errors ProxyPreserveHost not allowed here ProxyPass|ProxyPassMatch can not have a path when defined in a location. How can I set up a ProxyPass for a single virtual host?

• Cannot Update Adobe Creative Suit

  - by Lynda

  I am attempting to check for updates using the Adobe Application Manager on Windows 8 and I get this error: The update server is not responding. The server might be offline temporarily, or the Internet or firewall settings may be incorrect. I have seen this error before on Windows 7 and remembered that I needed to disable the Microsoft Virtual WiFi Miniport Adapter. I navigated to the correct place but the Miniport Adapter was not there. After a bit of searching across several forums I saw a recommendation to change <logLevel>2</logLevel> to <logLevel>10</logLevel>. I attempted that and again it still did not work. I have also tried disabling my anti-virus protection and disabling Windows Firewall. Neither worked. I am not sure what else to try or do at this point. Are there any other recommendations to solve this issue? Notes: I am running Windows 8 Pro using the Creative Cloud Version of CS6. I check for updates by choosing Help Updates from within any Adobe Application I originally posted this question on the Adobe Forums and received no help there.

• how many sites IIS 6 can handle

  - by Sarah Nasir

  Is there a limit for creating Sites in IIS. i have searched and some forums have it in discussion which says there is no limit. Someone mentioned that he has created upto 100,000 sites in IIS 6 but i dont know his server specs though. Personally i feel that whatever the limit of IIS, the resources will be run out well before the limit reaches. how do big sites like blogger and wordpress handle a huge number of sites on their server. Questions: 1) Is there an upper limit for IIS 6.0? if yes then what is it 2) What should be a good number of requests IIS should serve for a decent server? (I am not talking about dynamic requests on server or logs.) 3) Is there a way I can do the test run on my cloud to test the capability of my server. what factors should i keep in view. db request, page size, disk read/writes etc ? Response shall be highly appreciated.

• SSD Drive not being recongized in BIOS

  - by chobo2

  Well I bought my first drive Mushkin Chronos 180GB and got it installed in my computer and loaded up. I went to windows 7 and initialized the drive and then I installed "SSDlife Free" and loaded it up and my the SSD drive came up said it was "powered on 3 times"(thought it was odd but then thought maybe some testing???). I then restarted my computer and loaded into Acronis. Went to my SSD drive and make a partition called windows(made a basic logical partition). I then loaded up Norton ghost and wanted to copy my current windows onto the SSD drive on the partition I made found out I could not do it through the recovery disk so I made a backup of my windows drive and wanted to then restore it onto the SSD drive. Came back an hour later when the backup was done. I tried to restore the it on my SSD drive and could not find the partition so I loaded up Acronis again and it did not see it. I then went to the bios and saw only my other hard drive. What I tried Tried uplugging and replugging in both sata and power cables. Tried using the power and sata cable from the working drive and giving it the ones that SSD drive were using. Tried Sata AHCI Mode (Intel ICH9 Southbridge) Tried SATA PORT0-1 NATIVE MODE (Intel ICH9 Southbridge) Nothing worked. Software / hardware Windows 7 ultimate Gigabyte S-Series GA-P35-DS3L Mother board I hope someone has some ideas on why it is not being recognized.

• No apparent reason for high load average

  - by Oz.

  We have several web servers running on Amazon (ec2) c1.xlarge, over Amazon AMI. The servers are duplicates of each other, running the exact same hardware and software. Each server spec is: 7 GB of memory 20 EC2 Compute Units (8 virtual cores with 2.5 EC2 Compute Units each) 1690 GB of instance storage 64-bit platform I/O Performance: High API name: c1.xlarge A couple of weeks ago we have run a yum upgrade on one of the servers. Starting on this upgrade the upgraded server started showing a high load average. Needless to say, we did not update the other servers and we can not do so until we understand the reason for this behavior. The strange thing is that when we compare the servers using top or iostat, we can not find the reason for the high load. Note that we have moved traffic from the "problematic" server to the others, which have made the "problematic" server less crowded in terms of requests, and still his load is higher. Do you have any idea what could it be, or where else can we check? Many thanks for the help!
