  • DNS down in Anonymous attack

    - by Tal Weiss
    As I'm writing this our company website and the web-service we developed are down in the big GoDaddy outage resulting from an Anonymous attack (or so says Twitter). We used GoDaddy as our registrar and we use it for DNS for some domains. Tomorrow is a new day - what can we do to mitigate such outages? Simply moving to, say, Route 53 for DNS might not be enough. Is there any way to remove this single point of failure?

  • XServe won't let me log in

    - by niklassaers
    Hi guys, After a power-failure, my Xserve won't let me log in on the login screen. I can still SSH into the box and access its other services, but the login box just shakes when I write either a local username and password or an ldap based username and password (this server is the LDAP server). Any suggestions on how I can go about solving this problem? Cheers Nik

  • Success function not being called when form is submitted. jQuery / validationEngine / PHP form proce

    - by Tom Hartman
    Hi, I've been trying to figure out why the following script's success function isn't running. Everything in my form works perfectly, and the form contents are being emailed correctly, but the success function isn't being called. If anyone could review my code and let me know why my success function isn't being called I would very much appreciate it! Here is the HTML form with notification divs, which are hidden via css: <div id="success" class="notification"> <p>Thank you! Your message has been sent.</p> </div> <div id="failure" class="notification"> <p>Sorry, your message could not be sent.</p> </div> <form id="contact-form" method="post" action="" class="jqtransform"> <label for="name">Name:</label> <input name="name" id="name" type="text" class="validate[required] input" /> <label for="company">Company:</label> <input name="company" id="company" type="text" class="input" /> <label for="phone">Phone:</label> <input name="phone" id="phone" type="text" class="input" /> <label for="email">Email:</label> <input name="email" id="email" type="text" class="validate[required,email] input" /> <div class="sep"></div> <label for="subject">Subject:</label> <input name="subject" id="subject" type="text" class="validate[required] input" /> <div class="clear"></div> <label for="message">Message:</label> <textarea name="message" id="message" class="validate[required]"></textarea> <div id="check-services"> <input type="checkbox" name="services[]" value="Contractor Recommendation" /> <div>Contractor Recommendation</div> <input type="checkbox" name="services[]" value="Proposal Review" /> <div>Proposal Review</div> <input type="checkbox" name="services[]" value="Existing Website Review" /> <div>Existing Website Review</div> <input type="checkbox" name="services[]" value="Work Evaluation" /> <div>Work Evaluation</div> <input type="checkbox" name="services[]" value="Layman Translation" /> <div>Layman Translation</div> <input type="checkbox" name="services[]" value="Project Management" /> <div>Project Management</div> </div> <div class="sep"></div> <input name="submit" id="submit" type="submit" class="button" value="Send" /> <input name="reset" id="reset" type="reset" class="button" value="Clear" onclick="$.validationEngine.closePrompt('.formError',true)" /> </form> Here is the javascript: // CONTACT FORM VALIDATION AND SUBMISSION $(document).ready(function(){ $('#contact-form').validationEngine({ ajaxSubmit: true, ajaxSubmitFile: 'lib/mail.php', scroll: false, success: function(){ $('#success').slideDown(); }, failure: function(){ $('#failure').slideDown(); $('.formError').animate({ marginTop: '+30px' }); } }); }); And here is my PHP mailer script: <?php $name = $_POST['name']; $company = $_POST['company']; $phone = $_POST['phone']; $email = $_POST['email']; $subject = $_POST['subject']; $message = $_POST['message']; $services = $_POST['services']; $to = '[email protected]'; $subject = 'THC - Contact'; $content .= "You received a message from ".$name.".\r\n\n"; if ($company): $content .= "They work for ".$company.".\r\n\n"; endif; $content .= "Here's the message:\r\n\n".$message."\r\n\n"; $content .= "And they are interested in the services below:\r\n\n"; $content .= implode("\r\n",$services); if ($phone): $content .= "\r\n\nYou can reach them at ".$phone."."; else: $content .= "\r\n\nNo phone number was provided."; endif; $headers = "From: ".$name."\r\n"; $headers .= "Reply-To: ".$email."\r\n"; if (mail($to,$subject,$content,$headers)): return true; else: return false; endif; ?>

  • Py2exe, PyQt4 and Postgre Driver (QPSQL)

    - by Marshall
    Hi, I`m trying to freeze my application using Py2exe. My app uses PyQt4 and it apparently works fine with py2exe. But once I`ve uninstalled PyQt, it shows the following error: QSqlDatabase: QPSQL driver not loaded QSqlDatabase: available driver: QPSQL7 QPSQL Which doesn't make sense at all. If PyQt4 is still installed, it works just fine. This is my py2exe parameters: data_files = [ ('sqldrivers', [ 'C:\Python26\Lib\site-packages\PyQt4\plugins\sqldrivers\qsqlpsql4.dll' ]) ] setup(console=["delivery.py"], options={"py2exe" : {"includes" : ["sip", "PyQt4.QtSql", "PyQt4.QtWebKit", "PyQt4.QtNetwork"]}}, data_files=data_files)

  • Why does PSEXEC work if I don't specify a password?

    - by Kev
    When I run PSEXEC to launch a process on a remote machine, if I specify the password in the command line it fails with: PsExec could not start cmd.exe on web1928: Logon failure: unknown user name or bad password. psexec \\web1928 -u remoteexec -p mypassword "cmd.exe" If I just specify: psexec \\web1928 -u remoteexec "cmd.exe" and type in the password it works just fine. The originating server is Windows 2003 and the remote server is Windows 2008 SP2.

  • MSMQ Resilience

    - by Paddy Carroll
    I have a requirement for a resilient MSMQ setup on VMWare ESX5. I am aware that we cannot allow the queue storage to be shared as it must be installed on physical disk mount, e.g. it cant be an CIFS or DFS Share. The following constraints apply: We don't use windows clustering We dont't rely on hot standbys Is there a way I can replicate the queue storage to another platform so that it can assume MSMQ duties on failure of the primary platforms using any method including queue forwarding?

  • where on disk is space allocated for new files inside LVM lv with ext4 file system?

    - by Jost
    I run a multi-disk server with LVM2. Several large disks serve as LVM2 physical volumes for one volume group, containing one logical volume formatted with ext4. Nothing fancy, just your standard linear setup. Recently an additional, very small disk was added as physical volume to that volume group and I expanded both the logical volume, and the ext4 file system therein onto that disk. This lv is used to store incremental backups using rsync and is only about 30% full, there have rarely been any files deleted from it, only incremental writes. Now this new HDD I added to the pre-existing volume group has unexpectedly died on me, and the volume group won't come up because it is missing one physical volume. As fate will have it, this WAS the "in an event of catastrophic failure on the primary server"-backup, the event happened, the boss is not happy, so this kinda has to work... According to this (Part 3): http://www.novell.com/coolsolutions/appnote/19386.html it is possible to trick LVM into starting anyway by creating a new pv with identical metadata to the failed disk, which will make the volume accessible, but of course leave giant holes in the file system. I have'n tried it yet, because it involves repairing (writing to) the file system which eliminates the possibility of trying other things if it fails. Now my question is: How does this setup actually allocate disk space for new data? Is it allocated linearly from beginning to end of PVs, in the order they were added to the vg? Is it striped somehow in order to increase performance/balance load? since this defective disk was added only later to an existing lvm2 vg and lv, containing a half-empty ext4, what are the chances that there was never any data written to the defective disk? In other words: what are the chances of recovering all my data, even without the defective disk, by just starting the volume group as-is? Am I about to go spend $1500 on having 250GB of empty space recovered when I send the defective disk in for repair? Is there a way to check without mounting the file system and opening the files, hoping they contain something other than zeros? (comparing addresses of used data blocks inside ext4 to address ranges that were on the missing pv, something like that, preferably easy to automate) I know bitwise-copying the entire lv into an image file before trying to repair the ext4 would probably be a good idea, but since this lv is very large and I just suffered major file system failure on several systems it is probably a luxury I don't have... Any suggestions?

  • Can someone explain RAID-0 in plain English?

    - by Edward Tanguay
    I've heard about and read about RAID throughout the years and understand it theoretically as a way to help e.g. server PCs reduce the chance of data loss, but now I am buying a new PC which I want to be as fast as possible and have learned that having two drives can considerably increase the perceived performance of your machine. In the question Recommendations for hard drive performance boost, the author says he is going to RAID-0 two 7200 RPM drives together. What does this mean in practical terms for me with Windows 7 installed, e.g. can I buy two drives, go into the device manager and "raid-0 them together"? I am not a network administrator or a hardware guy, I'm just a developer who is going to have a computer store build me a super fast machine next week. I can read the wikipedia page on RAID but it is just way too many trees and not enough forest to help me build a faster PC: RAID-0: "Striped set without parity" or "Striping". Provides improved performance and additional storage but no redundancy or fault tolerance. Because there is no redundancy, this level is not actually a Redundant Array of Inexpensive Disks, i.e. not true RAID. However, because of the similarities to RAID (especially the need for a controller to distribute data across multiple disks), simple strip sets are normally referred to as RAID 0. Any disk failure destroys the array, which has greater consequences with more disks in the array (at a minimum, catastrophic data loss is twice as severe compared to single drives without RAID). A single disk failure destroys the entire array because when data is written to a RAID 0 drive, the data is broken into fragments. The number of fragments is dictated by the number of disks in the array. The fragments are written to their respective disks simultaneously on the same sector. This allows smaller sections of the entire chunk of data to be read off the drive in parallel, increasing bandwidth. RAID 0 does not implement error checking so any error is unrecoverable. More disks in the array means higher bandwidth, but greater risk of data loss. So in plain English, how can "RAID-0" help me build a faster Windows-7 PC that I am going to order next week?

  • howto plan RAID for ESX

    - by maruti
    eight 300GB SAS drives are available. Can ESX be put on one disk as RAID-0 and others as RAID-5 ? so that in the event of disk failure data (VMs) are safe. if os disk RAID-0 fails could that be installed on replacement disk and still be able to keep VMs running? if not RAID-1 for OS is only option for OS disk? please suggest any other RAID options.

  • Moving Windows XP from ICH10R RAID 5 to single disk using Linux [migrated]

    - by tudor
    A friend's machine running Windows XP refused to boot recently which is running 3 SATA disks on RAID 5 (which was previously upgraded from RAID 1 not by me). I have determined there to be a disk failure. The disks have been replaced many times in the past few years. I wish to backup the RAID5 partition before I try anything to fix it. The RAID chipset used is ICH10R/DO. So, I plugged in an extra IDE drive and an Ubuntu USB key and looked at the RAID. The partitioning is a mess, but I did find at least one degraded but working RAID array with two partitions, one 79GB and the other 86GB. Then I: 1) Partitioned my IDE disk using fdisk to have a partition of 80GB and bootable, and marked as NTFS. 2) dd the contents of the array to the partition 3) disconnected everything else 4) inserted a Windows XP CD and ran fixboot, fixmbr, and bootcfg. They all run ok and claim that they worked. (e.g. bootcfg detects the Windows partition, fixboot returns saying that it was written correctly.) However, I'm still getting an error like "DISK FAILURE, BOOT DISK NOT FOUND". I have tried running the GRUB rescue disk, which also runs ok, but won't boot into Windows. It just stops with a flashing cursor after chainloader +1, boot. One clue may be that the partitions appear to be wack. One disk has a 79GB RAID partition on a 500GB drive with a offset, the second disk has a 320GB RAID partition across the whole drive. Additionally, the BIOS lists the RAID size as being 149GB. I don't see how this works. How are they even assembling the array when the partitions are so different? I have also tried running the Windows XP automated repair tool, but that didn't work either. I'm presuming this is something simple. Perhaps Windows is attempting to boot into RAID and, upon not finding it, simply crashing? Perhaps the 79GB partitions offset means that it's looking into the disk by that much? Please help!! To clarify: I want to make the single IDE disk bootable with a copy of the array so that I can prove/disprove that it's just that Windows has become corrupted, and use windows tools to correct it before attempting the same thing on the RAID array. That way I have a working backup and can show the process I used to fix it.

  • Safer RAID5 rebuilds using partially failed disks?

    - by arcticmac
    There have been lots of articles posted recently about how RAID5 is dangerous because of long resilver times, and in particular because of increasing chances of encountering a URE during the resilver. Obviously this is a significant concern. However, it seems that in many cases of interest (as long as you're keeping some kind of eye on your disks), when it comes time to rebuild the array, the disk that I'm replacing is still mostly readable. If you try to explain this predicament to the average layperson, they are typically very confused as to why you have two almost completely functional disks but can't produce one working array. It seems to me that there ought to be some way to take advantage of this to make rebuilds safer, as long as I'm willing to have the RAID5 be read-only for a couple of days while it rebuilds. Conceptually, what I have in mind looks something like this: When a disk fails, immediately take the RAID5 offline or mount it read-only Attach a new disk (either in a spare bay, or externally via eSATA) and begin rebuilding it to replace the failed one. If known, perhaps start with the stripes in which the failure occurred, to minimize the chances of losing those if another disk fails. In the event that a second disk experiences a URE or other failure during the rebuild, try to source that data from the disk that is being replaced. Presumably if this happens, more rebuilding would be necessary. When complete, shut down the server, swap the replacement drive into the original bay if desired, and bring the array back up. Obviously such a process would not be appropriate for applications where uptime is critical or data loss cannot be tolerated, but it seems to me that this could help considerably to improve the reliability of RAID5. I assume that there's not a good way to implement a recovery like this at present, given that I haven't seen any indication of tools that are designed to do this, and that it seems like it would be rather obtuse to work out manually. Are there also technical issues with it that I haven't thought of (I'm still fairly new to RAID stuff)? Any thoughts on how hard something like this would be to implement (e.g. in linux md raid)?

  • MacBook Pro won't sleep when closing lid

    - by Eelco Visser
    My one month old MacBook Pro suddenly does not sleep anymore when I close the lid. There might be a relation to the Caffeine program that I installed recently. Caffeine prevents a Mac from going into sleep. But I have the problem when Caffeine is not even running. What reasons could there be for this problem happening? I'm hoping its a software problem instead of some hardware failure.

  • Hard disk with trustworthy SMART support

    - by Paggas
    Which hard disk drive do you suggest with trustworthy SMART diagnostics? That is, a hard disk that can truthfully report sector reallocations and other pre-failure indicators. I'm asking this because I have seen quite a few hard disks with SMART support fail with no warning in the SMART diagnostics, so a hard drive that can report such problems with some degree of reliability would be much appreciated :)

  • Backing Up vs. Redundancy

    - by TK Kocheran
    I'm currently in stage 2 of 3 of building my home workstation. What this means is that my RAID-0 array of solid state disks will be backed up nightly to a RAID-5 or RAID-6 array of traditional spinning hard disks. However, it recently dawned on me that redundancy is not backup. The main reason for setting up a RAID array with redundancy was to protect myself in the event of a drive failure to serve as an effective backup solution. Wait. What if a bolt of lightning finds a way to travel into my house, through my surge-protector, into my power supply and physically destroys all of my hard disks and SSDs? Well, in that case, I guess I'd be fine because I generally keep most important files (music, pictures, videos) stored in multiple places like on my laptop, my wife's laptop, and an encrypted USB hard drive. Wait. What if a giant hedgehog meteor attacks my house from space traveling at mach 3 and all machines and hard disks are blown to smithereens. Well, I guess I could find a way to do ridiculously slow and cumbersome rsyncs or backups to Amazon's Glacier. Wait. What if there's a nuclear apocalypse... and at this point I start laughing hysterically. At what point does backing up become irrelevant? I completely understand situation one (mechanical drive failure), situation two (workstation compromised or destroyed somehow), possibly even situation three (all machines and disks destroyed), but situation four? There's no questioning the need for backups. None. However, there are three questions I'd really like addressed: To what level should one backup? I definitely understand the merits of physical disk redundancy. I also believe in keeping important files on multiple machines and thinning out the possibility of losing all of my files. Online backups make sense, but they beg the following question. What should I be backing up remotely and how often? It's no problem storage-wise to back up important files (music, pictures, videos) and even configuration and temporal data for all of the machines in my network (all Linux based)... albeit locally. Transferring to the cloud is another story. Worst-case scenario, if I lost all of my configuration for my individual computers, the reality is that I probably lost the machines too. The cloud is a long way away from here; I can run backups over CAT-6 here and see 100MB/s easily, but I'm afraid that I'm only going to see 2MB/s at best when transferring up to the cloud.

    I have a SBS 2008 Server/Windows 7 environment. We have approx 25 users & 6 Networked printers. What is the recommended way/what are the advantages disadvantages of having all the printers shared through the Server 2008 Print server vs having workstations connect directly to the workstation printers. Off the top of my head using the server 2008 print server is a single point of failure but Should make it easier to deploy/manage the printers.

  • Can't get basic web servers working on EC2 RedHat

    - by Yarin
    I'm trying to get some basic Python web servers (Flask, Tornado) turned up on the EC2. On the Amazon-flavored Linux AMI (Amazon Linux AMI 2013.03.1) they work no problem, but the same web servers installed on the RedHat quicklaunch AMI (Red Hat Enterprise Linux 6.4) don't work at all- All I get is connection failure errors when I try to browse to them. Both these servers share the same security group, with the relevant ports (5000, 5010) open, so I'm trying to understand why RedHat would not be not working.
