• Auto-rebuild RAID6 with MDADM

  - by user65632

  Hello everybody, i'm new in this forum, and because I see that a lot of people get helped here, i'll ask my question here! I have a openSUSE 11.3 Linux computer with 5 disks of 1TB (WD enterprise disks) in it. with mdadm I configured an RAID6 device. Now, after a lot of thorough testing, i've noticed that when the computer goes down unsuspectedly it could happen (1 time out of 10) that while booting, the md0 device isn't recognised, and then the machine goes in "recovery mode", which means that i have to 'CTRL + C' it so it can boot to openSUSE. Once in openSUSE i have to readd the drive manually with 'mdadm /dev/md0 --add /dev/sdX'. After this everything works back fine (after resynching). So my question is: Is there a way to auto-rebuild the RAID6 device when there are problems? and how can I stop this "recovery mode" from happening. Because the computer will be in a place I can't go to, to connect a keyboard, 'CTRL + C' it just to get in openSUSE. If you could help me, I would be a very very very! happy man! :-) thanks in advance! Mikhail

• How to route public static IP to a virtual machine on a vmware ESXi host?

  - by Kevin Southworth

  I have 5 static IPs from my ISP (Comcast) and I have a physical machine with VMware ESXi 4.0 on it that is hosting multiple virtual machines. Right now I am just using the default vmware virtual network (vswitch0) with DHCP from the Comcast IP Gateway Router and everything is working fine. Each virtual machine can access the internet, etc. One of my virtual machines is a webserver (Windows Server 2008) and I want to assign it to 1 of my 5 static IPs so it's accessible from the public internet, while leaving the other VMs on the internal LAN still using DHCP. If I just plug my laptop directly into the Comcast IP Gateway (it has 4 ports on the back) and assign my laptop a Static IP using the windows networking dialogs, then I can hit my laptop from the public internet and it works great. However, if I try to do the same steps to set a static IP config on my Windows Server 2008 VM, it does not work. The VM cannot access the internet (open Firefox and try to visit google.com), and I cannnot see the VM from the public internet either. I'm assuming I'm missing something in the ESXi config somewhere, but I'm pretty new to ESXi and I'm not sure how to configure it to work this way.

• Scanning website for vulnerablities

  - by Kristen

  I have found that the local school's website installed a Perl Calendar - this was years ago, it has not been used for ages, but Google has it indexed (which is how I found it) and it full of Viagra links and the like ... program was by Matt Kruse, here is details of the exploit: http://www.securiteam.com/exploits/5IP040A1QI.html I've got the school to remove that, but I think they also have MySQL installed and I'm aware that out-of-the-box there have been some exploits of Admin Tools / Login in old versions. For all I know they also have PHPBB and the like installed ... The school is just using some cheap, shared hosting; the HTTP response header I get is: Apache/1.3.29 (Unix) (Red-Hat/Linux) Chili!Soft-ASP/3.6.2 mod_ssl/2.8.14 OpenSSL/0.9.6b PHP/4.4.9 FrontPage/5.0.2.2510 I'm looking for some means of checking if they have other junk installed (quite possibly from way back, and now unused) that might put the site at risk. I'm more interested in something that can scan for things like the MySQL Admin exploit rather than open ports etc. My guess is that they have little control over the hosting space that they have - but I'm a Windows DEV, so this *nix stuff is all Greek to me. I found http://www.beyondsecurity.com/ which looks like it might do what I want (within their evaluation :) ) but I have a worry about how to find out if they are well known / honest - otherwise I will be tipping them a wink with a Domain Name that may be at risk! Many thanks.

• How do I disable the firewall on blackberry?

  - by user15660

  I own a Blackberry 9630 tour.(Sprint). The firewall is enabled with a lock sign and grayed out. I'm not able to disable it. Because of this many of my blackberry apps don't work as it gives a message "The application has tried to open a connection that's not allowed by your IT policy". I tried all options and there's nothing to disable. This is a personal blackberry and I don't have an IT policy on it. I did all methods like wiping, formatting/resetting to factory settings acc. to blackberry site by running their reset app from PC etc etc. but nothing works I tried CrackUtil for blackberry and that worked and wiped the blackberry. I restored my bb and started using it just to notice that the firewall is enabled back after a desktop manager connection to PC. I even made sure the policy.bin file on PC is a regular one with no IT policy. How do I get this disabled? I had the same problem on my old blackberry 8330 and crackutil disabled the firewall. but after a few days after a desktop manager update of blackberry OS and other small stuff the firewall got enabled again. Please give me a solutions to disable the firewall on blackberry

• Windows Server 2008 backup VHD's - is it possible to mount/open in Windows 7?

  - by Simon

  Hi All, Is it possible to mount the VHD files created by the Windows Server 2008 backup utility onto a Windows 7 (release) client? Following an array failure I was very worried that there was a problem with both the backup sets on different USB drives as attaching the VHD to a Win 7 box did not show the expected structure (instead they behaved like unformatted disk space). Subsequently, I've attached the backup drive to a 2008r2 machine that I'd intended to be the replacement and the backup set can be browsed without issue (seemingly). When the new disks arrive I'll go through the recovery process and see where we are, but it looks promising so far. Is it simply the case that you can't take server created VHD's and mount them on desktop machines? (Rather than hyper-ventilating at the thought of years of lost photos and email, I'm now just mildly curious) Edit:One thing that has confused things is that the backup utility on Win7 is more restrictive about restoring from external devices than the equivilent on 2008r2. With r2, I can restore files 'from another server' and browse to external storage. Win7 only allows the back to be located on a network share. Once my box of new disks arrive and I've got something to restore onto, I'll move the smaller of the backup VHDs onto network storage reachable by Win7 and see if the VHD is readable. I haven't read up on the VHD process used by the backup app - I'm assuming it's a base VHD and differencing files used for incremental backups and that the restore app understands this. Finally: In retrospect the question should have been, 'can I restore a 2008r2 backup set via a Win 7 client' Thanks

• 550 Requested action not taken: mailbox unavailable

  - by Porch

  I setup a small box with Server 2003 64bit to be used as a webserver and email server for a small school. Real simple stuff for a few users. A simple website and a handful of emails. rDNS and spf records setup and pass every test I found including test at dnsstuff.com. Email sending to almost every email address (google, hotmail, aol, whatever) works. However, with one domain, I get an bounce back with the error. 550 Requested action not taken: mailbox unavailable It's another school running Exchange judging from some packet sniffing with WireShark. Every email on this domain I have tried sending to gives this error. The email address is valid as I can send to it from my personal, and gmail account without a problem. Does anyone know of some anti-spam software that gives an 550 error like the above? What else could this be? Thanks for any suggestions.

• Hiera datatypes wont load in Puppet

  - by Cole Shores

  I have spent a couple of days on this, followed the instructions on http://downloads.puppetlabs.com/docs/puppetmanual.pdf and even the Puppet Training Advanced Puppet manual. When I run a test against it, the results always come back as 'nil' and Im not sure why. I am running Puppet 3.6.1 Community Edition, with Hiera 1.2.1 on SLES 11.

• How to add a privilege to an account in Windows?

  - by mark

  Given: A VM running Windows 2008 I am logged on there using my domain account (SHUNRANET\markk) I have added the "Create global objects" privilege to my domain account: The VM is restarted (I know logout/logon is enough, but I had to restart) I logon again using the same domain account. It seems still to have the privilege: I run some process and examine its Security properties using the Process Explorer. The account does not seem to have the privilege: This is not an idle curiousity. I have a real problem, that without this privilege the named pipe WCF binding works neither on Windows 2008 nor on Windows 7! Here is an interesting discussion on this matter - http://social.msdn.microsoft.com/forums/en-US/wcf/thread/b71cfd4d-3e7f-4d76-9561-1e6070414620. Does anyone know how to make this work? Thanks. EDIT BTW, when I run the process elevated, everything is fine and the process explorer does display the privilege as expected: But I do not want to run it elevated. EDIT2 I equally welcome any solution. Be it configuration only or mixed with code. EDIT3 I have posted the same question on MSDN forums and they have redirected me to this page - http://support.microsoft.com/default.aspx?scid=kb;EN-US;132958. I am yet to determine the relevance of it, but it looks promising. Notice also that it is a completely coding solution that they propose, so whoever moved this post to the ServerFault - please reinstate it back in the StackOverflow.

• ESX 4.0 space: DASD, NAS, or ?

  - by thormj

  I put together an ESX box for better management, but its performance is a WTF item; I'm a noob at dealing with ESX, so I'm looking for a laundry-list of reading material to help me straighten this out so I can go back to .NET programming. Current storage system: We're running Raid5+Hotspare (8x500 GB spindles) on a PERC6i on a Dell 2910. Due to ESX limitatios, the PERC is showing the storage as 1x2TB + 1x800GB "partitions." I'm not sure of the setup's configuration (stride / stripe / ???) at all. Our Applications We have a SBS server as well as a minor (2x50 GB, but growing at 10GB/month) database server... Our application that lives on the database VM is CPU and I/O insense; it's a database churning excercise mixed in with a lot of computation on the data (fixing that performance is what I'm supposed to be working on)... Perfomance Issue When I do a backup, restore, or worse (copy a backup from 1 vm to another to move it to the QA VM), the entire system slows to a crawl (even "unrelated" VMs). I originally thought a DASD situation would be quite good since you had PCI-x bandwidth, but the systemwide slowdown is killing productivity. Questions What should I do to make an intelligent decision about NAS vs RAID vs SAN vs DASD? Are there sweet spots/ugly spots in the storage setup? Can you use a SSD PCI-X card in ESX for the tempdb? Good/Bad idea? Is there any way to "share" some image in a copy-on-write fashion? Most of the "Backup-Copy-Restore" is to "put a clean image on the dev boxes"; if I could have them "share" the master image, the "big copy" (2x50 GB) would only need to be done once per week instead of once per dev per week...[runtime performance isn't a concern with the dev boxes, but the backup/copy/restore kills production, SBS, and everything else on the box]

• SATA Windows 7 Problems

  - by Isaacs

  Scenario: Core 2 Duo processor, Gigabyte MB, 4 SATA Western digital 500 GB hard drives, windows 7 64 bit. Problem: Copying data from USB or among SATA hard drives is faulty. When trying to copy 20GB from one HD to another it starts off with normal ~14-15 MB/s transfer rates and eventually bogs down to < 120KB/s transfer rates. If I leave it alone over night I come back with my computer crashed and setting at BIOS detecting hard drives. Troubleshooting: Removed all but 1 HD with OS on it, everything seems to be happy. I can copy large files from USB HD to main/single HD. Ran SpinRite on all hard drives, no errors found. Tried adding one HD to machine and problem exists, tried switching SATA cables, and SATA ports on MB. Reinstalled windows 7 x2 (from different disks..). Oddly enough if I boot to a ubuntu everything works fine. Getting ready to purchase a new MB, but wanted to see if anyone had suggestions. Thanks!

• Forwarding HTTP Request with Direct Server Return

  - by Daniel Crabtree

  I have servers spread across several data centers, each storing different files. I want users to be able to access the files on all servers through a single domain and have the individual servers return the files directly to the users. The following shows a simple example: 1) The user's browser requests http://www.example.com/files/file1.zip 2) Request goes to server A, based on the DNS A record for example.com. 3) Server A analyzes the request and works out that /files/file1.zip is stored on server B. 4) Server A forwards the request to server B. 5) Server B returns file1.zip directly to the user without going through server A. Note: steps 4 and 5 must be transparent to the user and cannot involve sending a redirect to the user as that would violate the requirement of a single domain. From my research, what I want to achieve is called "Direct Server Return" and it is a common setup for load balancing. It is also sometimes called a half reverse proxy. For step 4, it sounds like I need to do MAC Address Translation and then pass the request back onto the network and for servers outside the network of server A tunneling will be required. For step 5, I simply need to configure server B, as per the real servers in a load balancing setup. Namely, server B should have server A's IP address on the loopback interface and it should not answer any ARP requests for that IP address. My problem is how to actually achieve step 4? I have found plenty of hardware and software that can do this for simple load balancing at layer 4, but these solutions fall short and cannot handle the kind of custom routing I require. It seems like I will need to roll my own solution. Ideally, I would like to do the routing / forwarding at the web server level, i.e. in PHP or C# / ASP.net. However, I am open to doing it at a lower level such as Apache or IIS, or at an even lower level, i.e. a custom proxy service in front of everything. Thanks.

• With no password expire notification at logon in Windows 7, how are you configuring password expire

  - by J. L.

  To my understanding, Windows 7 users do not receive password expiration notification during the logon process - it occurs strictly from the system tray. We currently have tray balloon notifications disabled to lessen user distraction, and I expect the password change process is a smoother one during the logon process rather than in an existing session. As a result, users will get prompted to change their passwords at expiration. The users also connect to Terminal Services boxes, but receive the advanced notification for password expiration there. So, Windows 7 is not notifying, but TS/RDS and XP boxes are. Any guidance on configuring this? Personally, I would turn off all expiration notices, but I understand most users would prefer to see the notification. Thoughts? Any GPO or other settings I might be overlooking? The interactive logon setting below is already enabled for our Win7 workstation GPO. My thought is balloon notifications will get turned back on for Windows 7, but I wanted to see if anyone was aware of alternatives. Thanks.

• How do I calculate clock speed in multi-core processors?

  - by NReilingh

  Is it correct to say, for example, that a processor with four cores each running at 3GHz is in fact a processor running at 12GHz? I once got into a "Mac vs. PC" argument (which by the way is NOT the focus of this topic... that was back in middle school) with an acquaintance who insisted that Macs were only being advertised as 1Ghz machines because they were dual-processor G4s each running at 500MHz. At the time I knew this to be hogwash for reasons I think are apparent to most people, but I just saw a comment on this website to the effect of "6 cores x 0.2GHz = 1.2Ghz" and that got me thinking again about whether there's a real answer to this. So, this is a more-or-less philosophical/deep technical question about the semantics of clock speed calculation. I see two possibilities: Each core is in fact doing x calculations per second, thus the total number of calculations is x(cores). Clock speed is rather a count of the number of cycles the processor goes through in the space of a second, so as long as all cores are running at the same speed, the speed of each clock cycle stays the same no matter how many cores exist. In other words, Hz = (core1Hz+core2Hz+...)/cores.

• Troubleshooting a Windows 7 PC that wouldn't sleep

  - by NPE

  I have a new Windows 7 PC that wouldn't sleep (not just automatically, but also when specifically told to). The screen goes black momentarily, but within two seconds the machine comes back as if nothing has happened. I tried powercfg energy. This produces some errors quoted at the bottom of this post, plus some warnings about timer resolution. There are no USB devices connected other than wireless keyboard + mouse (Logitech MK250); I tried unplugging them to no effect. The motherboard is Asus P7P55D-E. powercfg lastwake says "Wake History Count - 0", which I take to mean that it never actually went to sleep. I dual boot into Ubuntu, and was having exactly the same problem on the Linux side. That turned out to do with USB 3.0, which I've now disabled in the BIOS. This has solved the problem on the Ubuntu side of things, but made no difference to Windows 7. Any suggestions? Suspend:USB Device not Entering Suspend The USB device did not enter the Suspend state.

• Advanced Linux file permission question (ownership change during write operation)

  - by Kent

  By default the umask is 0022: usera@cmp$ touch somefile; ls -l total 0 -rw-r--r-- 1 usera usera 0 2009-09-22 22:30 somefile The directory /home/shared/ is meant for shared files and should be owned by root and the shared group. Files created here by usern (any user) are automatically owned by the shared group. There is a cron-job taking care of changing owning user and owning group (of any moved files) once per day: usera@cmp$ cat /etc/cron.daily/sharedscript #!/bin/bash chown -R root:shared /home/shared/ chmod -R 770 /home/shared/ I was writing a really large file to the shared directory. It had me (usera) as owning user and the shared group as group owner. During the write operation the cron job was run, and I still had no problem completing the write process. You see. I thought this would happen: I am writing the file. The file permissions and ownership data for the file looks like this: -rw-r--r-- usera shared The cron job kicks in! The chown line is processed and now the file is owned by the root user and the shared group. As the owning group only has read access to the file I get a file write error! Boom! End of story. Why did the operation succeed? A link to some kind of reference documentation to back up the reason would be very welcome (as I could use it to study more details).

• Why is my biometric logon method no longer default and how to fix it? Win 7-based lenovo laptop

  - by StormRyder

  My laptop has been having some random problems with hibernating properly. That is a whole another topic that I still haven't resolved, but this is a different issue. The issues are connected, I guess, because one time after my computer experienced a failed hibernate, my login screen changed: since then my login screen always appears as the standard one with a prompt to type in a password. I can still use the finger scanner by clicking "other credentials" button. But that's annoying having to do that every time; previously the prompt to use finger scanner was the default one, whereas the typing password access was the alternate. How do I bring this arrangement back? In other words, how to switch the default from the type password prompt to the finger scan prompt? From online searches, I have only found discussions of turning the biometric access on or off... but clearly it is turned on and working, since I can use it. It's just not the default for some reason...

• Serving and caching content from Amazon S3 with Tomcat

  - by Rob

  Hi all, We're looking to serve a range of content using Amazon S3 as a store for the content and Tomcat to host the web application. The content is divided into free and paid for content. We intend to authenticate the users when they access the web application running in Tomcat. Based around their authentication we are able to tell if the user has access to paid for content or simply free stuff. So I envision the flow of a request being something like this: Authenticated request to Tomcat If user is "paid" user, display links to premium content Direct requests for paid content back through Tomcat to prevent direct access to it by non-paying users. Tomcat makes request to S3 through a web cache to keep our costs down Content is returned to user. As we have to pay for each request to S3, I'd ideally like to cache content locally to the Tomcat instance after it has been requested for the first time to keep costs to a minimum and to speed things up. I would also like to be able to invalidate this cache if we publish fresh content to S3. So to confirm my proposal: Client Request - Tomcat - Web Cache - S3 To invalidate the cache, I was thinking of using something like PubSubHubbub with the cache waiting for updates to the feed for content that it should invalidate. I'd appreciate some general feedback on this approach as I've no real experience of caching and I'm sure I've made some invalid assumptions. I'd also appreciate any recommendations for caching technologies. Thanks.

• Which is the fastest way to move 1Petabyte from one storage to a new one?

  - by marc.riera

  First of all, thanks for reading, and sorry for asking something related to my job. I understand that this is something that I should solve by myself but as you will see its something a bit difficult. A small description: Now Storage = 1PB using DDN S2A9900 storage for the OSTs, 4 OSS , 10 GigE network. (lustre 1.6) 100 compute nodes with 2x Infiniband 1 infiniband switch with 36 ports After Storage = Previous storage + another 1PB using DDN S2A 990 or LSI E5400 (still to decide) (lustre 2.0) 8 OSS , 10GigE network 100 compute nodes with 2x Infiniband Previous experience: transfered 120 TB in less than 3 days using following command: tar -C /old --record-size 2048 -b 2048 -cf - dir | tar -C /new --record-size 2048 -b 2048 -xvf - 2>&1 | tee /tmp/dir.log So , big problem here, using big mathematical equations I conclude that we are going to need 1 month to transfer the data from one side to the new one. During this time the researchers will need to step back, and I'm personally not happy with this. I'm telling you that we have infiniband connections because I think that may be there is a chance to use it to transfer the data using 18 compute nodes (18 * 2 IB = 36 ports) to transfer the data from one storage to the other. I'm trying to figure out if the IB switch will handle all the traffic but in case it just burn up will go faster than using 10GigE. Also, having lustre 1.6 and 2.0 agents on same server works quite well, with this there is no need to go by 1.8 to upgrade the metadata servers with two steps. Any ideas? Many thanks Note 1: Zoredache, we can divide it in two blocks (A)600Tb and (B)400Tb. The idea is to move (A) to new storage which is lustre2.0 formated, then format where (A) was with lustre2.0 and move (B) to this lustre2.0 block and extend with the space where (B) was. This way we will end with (A) and (B) on separate filesystems, with 1PB each.

• How can I set the CD audio volume in Linux?

  In Windows 7 Control Panel - Sound - Sound Properties window there's an slider for setting CD Audio volume: And it's pretty strange that I can't find corresponding one in generic Linux mixers: alsamixer or amixer. I connected a CD drive to try to set CD audio volume with cdcd (CD Player): $ cdcd setvol 0 Invalid volume It isn't actually an invalid volume, it is because ioctl() call fails.

Though I don't think it's the case: $ lsmod | grep snd snd_mixer_oss 22602 0 snd_hda_codec_hdmi 32474 1 snd_hda_codec_realtek 223867 1 snd_hda_intel 33773 4 snd_hda_codec 127706 3 snd_hda_codec_hdmi,snd_hda_codec_realtek,snd_hda_intel snd_hwdep 13668 1 snd_hda_codec snd_pcm 97188 3 snd_hda_codec_hdmi,snd_hda_intel,snd_hda_codec snd_seq_midi 13324 0 snd_rawmidi 30748 1 snd_seq_midi snd_seq_midi_event 14899 1 snd_seq_midi snd_seq 61896 2 snd_seq_midi,snd_seq_midi_event snd_timer 29990 2 snd_pcm,snd_seq snd_seq_device 14540 3 snd_seq_midi,snd_rawmidi,snd_seq snd 78855 19 snd_mixer_oss,snd_hda_codec_hdmi,snd_hda_codec_realtek,snd_hda_intel,snd_hda_codec,snd_hwdep ,snd_pcm,snd_rawmidi,snd_seq,snd_timer,snd_seq_device soundcore 15091 1 snd snd_page_alloc 18529 2 snd_hda_intel,snd_pcm All I need is just mute or set to 0 volume level of CD Audio channel, like I did in Windows 7, to get rid of sibilant noise in the speakers.

• How Can I Make Apache Stop Serving ALL Unknown File Types (like .php~)?

  - by user223304

  I am coming from IIS and moving to Apache and recently found out that Apache by default serves up files of an unknown file extension as PURE TEXT. This can be an issue if a user uses certain programs that back up .php files as .php~. Then the .php~ file becomes completely readable by simply navigating to it in a browser. To make matters worse these .php~ files are often considered 'hidden' in the linux environment from the user so some may not even know they exist. Bots have been created around this fact that scour the internet looking for popular file name backups and extracting potentially secure info from them. I already know how to stop serving up .php~ files or any specific file extensions. I also know not to use any editors that would save backup files like this. My question is, how can I stop this default Apache behavior of serving up ANY non-MIME file type at all? I just don't like the this behavior and would like to stop it. I don't want it serving up .aspx~, .html~, .bob, .carl, no extension or anything else that is not a real MIME type. I know that I can probably go and use a directive to first Deny access to all file types. Then add the ones I want to serve out one by one. But I'm wondering if there's an easier/quicker way. Thanks for any help.

• flowchart for debugging a slow/unresponsive server

  - by davidosomething

  So the server is slow: Roll back to the previous known working build - Success? Code problem - Fail? Go on. Ping ip address - Success? maybe a DNS problem, go on. - Fail? Server or connection problem, go on. Ping and tracert your domain.com from inside your network - previous success - fail: DNS problem - success? go on. - previous fail and: - Fail? Go on, could be you or network. - Success? Go on. Try it from outside your network (http://centralops.net/co/) - Fail? The server's network connection sucks. - Success? If inside network was fail, your network sucks. Check the server load: CPU/RAM usage. Is it overloaded? - Yes. Who's the culprit? Kill some processes/reboot. - No? Go on. what other steps should i add?

• Websockets Server with Fault-Tolerance and Durable Message Store

  - by smitchell360

  I am starting to experiment with websockets. Does anyone know of a websockets server (open source or paid) that provides a durable store of the websocket "channel"? All of the examples that I have found do not address durability -- if a websockets server goes down, all "channel" data is lost. Services such as Pusher do not really discuss whether they address the durability issue (and I have not received a response from tech support yet). Happy to roll my own, but would rather not reinvent the wheel. EDIT: I'm not looking for websockets 101 information. That is readily available and understood. I'm looking for a server (open source or paid) that supports websockets and has a durable store for the websocket data so that, in the event that a server fails, a new server can take over where the original one left off. Two main purposes: 1. support failover scenarios contemplated by the websockets Network Working Group http://tools.ietf.org/html/draft-ibc-websocket-dns-srv-02#section-5.1 (most importantly so that missed messages are sent when a client connects to a failover server) 2. support scenarios where new subscribers must receive all past messages that were published. Of course this can be handled at the application layer...but that is not what I am looking for. EDIT So, after some research the following installed options seem to be the most robust: Kaazing Migratory Migratory (http://migratory.ro) Hosted services that seem "real" Pusher (great API but no history feature yet) PubNub (has history) All of the above services have graceful fallback to other communication methods if websockets are not available. I was not able to find any open source that provided "out of the box" clustering, fail-over, and a durable message store to play back history. There are some projects that may serve as good starting points, but not exactly what I am looking for.

• Enable re-attached mouse/keyboard via ssh?!

  - by aidan

  I had Ubuntu 9.10 x64 Desktop installed on a nettop I have (that I normally run headless), and yesterday I decided to take the plunge and update to 10.04. So, I plugged in a screen and usb mouse/keyboard, booted up and set to work. It was 1am, and it was telling me it had 3hrs left to install all the new packages, so I unplugged the screen and usb mouse/keyboard, left the box running, and went to bed. This evening, I plugged it all back in again to check progress. It's asking if I want to remove obsolete packages. I do, but neither the mouse nor keyboard work! I can access the box via SSH like I normally do; is there any way I can re-enable the keyboard from there? I'm reluctant to restart the box (via ssh) mid-way through such a complicated upgrade.

• In spite of correct DNS, Exchange sending to wrong destination server for single outbound domain

  - by beporter

  My company uses an SBS 2003 server and makes use of Exchange to host our own email. We also have a linux server hosting domains for some of our clients. In order for us to send to those clients, we had internal DNS set up to shadow the client domains to provide "correct" MX records inside our network. For example, public DNS for a domain abc.com might point to 1.2.3.4, but internally we have MX records set up to route mail for abc.com to 172.16.0.4, which is the linux email server. This setup was entirely functional; this is just back story. We've recently moved one of our client domains from our internal linux server to an external email provider. When we did that, we naturally deleted our internal shadow DNS records so our Exchange server would fetch correct (public) DNS records and route mail out to the new external host. This has NOT had any effect on Exchange though. Even after rebooting the Exchange server and completely flushing the DNS cache (nslookups on the Exchange machine itself correctly resolve to the new external address) Exchange still attempts to deliver messages for the domain to our internal server! Exchange correctly routes to all other internal and external domains when sending email. Somehow Exchange is trying to deliver to a machine that by all accounts it has no business trying to use for just this one domain. Is there a DNS cache that Exchange uses internally? Is there a way to flush that internal cache? What else could I be missing?

• Create "raw disk file" from WIM file

  - by Joe Baltimore

  First timer here. I've searched around here, but haven't found a question like the one I have. Apologies if I missed it. The challenge at hand: produce a "raw disk image file" from a given WIM file. What I am pursuing so far is to use imagex.exe with the "/apply" operation to take the WIM and lay it down in a directory on a server. That seems to produce all the necessary "stuff" I need in that directory. How would I take that content and produce a "raw disk image file"? I'm told the definition of "raw disk image file" is a block-by-block copy of the disk image, which I hope is the output of the "imagex.exe /apply" command I use currently, but stored in a single file I can hand back to another system in our solution. imagex.exe /apply image.wim 1 R:\WimImagePoint I would like to take the contents of R:\WimImagePoint and produce the elusive (to me) "raw disk image file". ISO is not what they want, nor is anything requiring winPE. Any pointers? External utilities' references are welcome. Would like to avoid unmanaged code solutions as much as possible, but will entertain them if that's the only route. Also, I am not married to the idea of imagex /apply as the starting point, it's just the comfort zone so far.
