• Apache returns truncated image

  - by ChronoFish

  I am bringing up an image directly through firefox (no PHP or other scripting code) and it appears that Apache is returning either a truncated image or a corrupted image. I get the top 5-10% of the image. It appears that I get complete width and height info. If I hit "refresh" (in firefox) I get about 5 more lines of the image. And if I hit refresh again I get another 5 lines. In IE I get the same initial 5-10% of the top of the file. But refresh does not give me any more. Bringing the image up across the network through a mapped-drive reveals the entire image. (so the image(s) itself seems to be okay). (If I point firefox to the image via mapped-drive rather than through Apache firefox brings the image up just fine. So it does seem to be Apache at issue) Any ideas?

• How to install anti-virus without administrative rights?

  - by Rohit

  In situations where the PC has no CD drive and operating a guest account with limited privileges, how to install an anti-virus tool? Malware is not permitting to open any anti-virus vendor's site and also blocking all sites opened via Google that contain the term "online scan". I somehow managed to download through mirror links with a Download Manager as the browser's download was blocked by the malware. But the problem didn't end there. After I downloaded the anti-virus tool, it failed to install because it needed administrative rights. The user didn't know the administrator password. I tried via command line with runas, but it also asks for the administrator password. The OS is Windows XP. How to deal with these type of malwares if there is a scenario that CD drive is not there only Internet is there?

• rsync creating thousands of ..ds_store files from mounted volume

  - by daniel Crabbe

  I've been using rsync on OS X to sync all our website admins. It was working fine until the OS X 10.6.3 update! Now it creates thousands of empty (0-kb) folders. It only does it when synching to a mounted network drive (which we need to do) as when I sync to my local drive it works as usual! I've tried excludes which don't seem to be working... also tried a different version of rsync so it's an OS X issue. echo "" echo "~*~*~*~*~*~*~*~*~*~*~*~*~*" echo " SYNCING up KINEMASTIK" echo "~*~*~*~*~*~*~*~*~*~*~*~*~*" /usr/local/bin/rsync -aNHAXv --progress --exclude-from 'exclude.txt' /Volumes/Groups/Projects/483_Modern_Activity_Website/web/youradmin/ /Users/dan/Dropbox/documents/WORK/kinemastik/WEBSITE/youradmin/ echo "" echo "~*~*~*~*~*~*~*~*~*~*~*~*~*" echo " SYNCING up CHRIS BROOKS YOURADMIN" echo "~*~*~*~*~*~*~*~*~*~*~*~*~*" /usr/local/bin/rsync -aNHAXv --progress --exclude-from 'exclude.txt' /Volumes/Groups/Projects/483_Modern_Activity_Website/web/youradmin/ /Volumes/Groups/Projects/516_ChrisBrooks/website/youradmin/ Has anyone experienced the same problem?

• HD movies stutter.

  - by Absolute0

  I just put together a new system build in the hopes that all of my daily tasks would run smoothly and without any hiccups. Unfortunately I am still seeing some sound and sometimes video stuttering when playing HD movies in VLC (no problems with xvid/divx files). My setup is as follows: Intel core i5 750 quad core 2.66mhz 4GB ram asus p55 motherboard radeon hd 5570 video card 650gb 7200rpm western digital sata HDD 23" Nec ea23wmi monitor Operating System: Windows 7 What might be the main bottleneck that needs upgrading to fix my delays? Seems like the hard drive might be the problem but anything faster than 7200rpm is beyond my budget for a decent hard drive. Could it be anything else?

• How to copy files from shadow copy with long source path

  - by Jake

  The files and folders in my shared network drive (set up with DFS) were mass deleted. Currently I am trying to recover the files from the shadow copy "Previous Version". Problem is, thousands of files are deeply nested with long paths making the file path too long. When copying, it shows the dialog "Source Path Too Long". My guess is that the file path just barely hits the limit when saved into the network drive, but shadaw copy service appends the date and time to the folders so the path character limit is exceeded. How else can I copy the files from shadow copy?

• How to copy a dynamic TrueCrypt volume quickly?

  - by Ivan

  I have created a dynamic TrueCrypt volume file, set it size to 40 GiB and put about 20 GiB of files on it. When I open the volume file properties it says "Size: 40.0 GB, Size on disk: 23.0 GB". When I try to move the volume file to another physical partition it takes a lot of time as it tries to copy all the 40 GB instead of just 20 GB that the volume file actually takes. Also, when it is less than 40 GB free on the target drive it says insufficient space even though it is more than enough space considering how much does the image file actually take. How do I overcome this? Creating a new volume file on the target drive works but needless to say I'd like a better solution.

• PowerShell fomat.ps1xml not reachable

  - by blsub6

  I'm trying to load Exchange Management Shell and it gives me a big 'ol red error that says: Import-Module : There were errors in loading the format data file: Microsoft.PowerShell, , %APPDATA%\Roaming\Microsoft\Exchange\RemotePowerShell\DOMAINNAME.format.ps1xml : File skipped because of the following validation exception: File %APPDATA%\Roaming\Microsoft\Exchange\RemotePowerShell\DOMAINNAME.format.ps1xml cannot be loaded. The file %APPDATA%\Roaming\Microsoft\ExchangeRemotePowerShell\DOMAINNAME\DOMAINNAME.format.ps1xml is not digitally signed. The script will not execute on the system. Please see "get-help about_signing" for more details... The %APPDATA% is stored on an external server on my network (that I can ping to without problems). I am missing a ton of PS cmdlets too, which I'm presuming are stored in '*.format.ps1xml' I tried finding the directory in which format.ps1xml is supposed to reside on the external server and it's not even created. Can someone tell me where to start?

• Dual booting Windows and Arch Linux (with GRUB2) - after using Windows, Windows Boot Manager made first in boot priority list

  - by louis058

  I am dual booting Windows 7 and Arch Linux (both 64bit), with GRUB2, using the 64-bit EFI version. I partitioned my drive into a GPT drive and installed Windows first according to this guide. I then installed Arch Linux using the Beginner's Guide, installing grub2-efi-x86_64 in the process. Everything is working fine now, but with one problem. I can set the boot priority in BIOS (or is it UEFI?) to have GRUB boot try and boot before Windows Boot Manager. Then I chainload Windows Boot Manager using GRUB. However, when I actually use Windows in this manner, upon shutting down and turning on again, or rebooting, Windows seems to set Windows Boot Manager first in the priority list again, with the result being I have to manually set GRUB again, or I can't boot into Linux. My motherboard is an Asrock H61M/USB3, if that helps. I want to know how to turn off this behaviour.

• 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.

• Windows 7 - Move location of Eventlog

  - by Jörg B.

  I am having a particular nasty problem of my main system drive 'disappearing' all of the sudden while the system is running. The vendor somewhat knows about this but has not managed to fix it completely over multiple fw iterations. Problems I have with the support is that I cannot provide any particular system log files/entries to further analyse what might have been going on because, well - windows cannot write to its 'lost' drive before bsod'ing. Is there any way to configure where Windows 7 stores its event logs so that I could specify a second physical hdd?

• Unable to play bluray movies or see bluray discs

  - by Jason Shultz

  I have a Optiarc BD ROM BC-5500S ATA Device and when I put bluray discs into the drive the computer doesn't read them. I hear the drive make 3 noises as if it's trying to read them. Nothing shows up in windows explorer. I am running windows 7 64bit. I can read DVDs and CDs just fine. Bluray seems to be the only problem. I have installed PowerDVD9, HP DVD Play and HP DVD Media Smart and nothing helps. My laptop is a hp dv7 1273cl. I bought it before the free upgrades to windows 7 were available so I wasn't able to get the upgrade and so HP won't assist me beyond telling me to format and reinstall Vista.

• Can SATA be used to connect computers?

  - by André

  Can SATA be used to connect two computers together, just like a crossover Ethernet cable would do ? I know SATA has no "networking" features and even though a controller may have multiple ports, the drives don't "see" each other, and that in SATA one device acts as the host (the computer) and the other device is some kind of "client" (the storage drive). But still, did anyone attempt to make a kernel module that would make one computer appear as a "client" (so that the host's SATA controller detects it as a standard hard drive) and then set up like a pseudo-Ethernet link or a very high speed serial link (and then run pppd on it and do networking) ? Note : I know this is an unprofessional and totally stupid idea, I'm just asking out of curiosity.

• Alternative to Windows Home Server (WHS) backups

  - by Adam Tegen

  Since Microsoft announced the end of life for WHS, are there any alternatives? Specifically, I am interested in recovering from a catastrophic disk failure with WHS. For example, this is my ideal scenario when a desktop hard-drive fails (has a bad virus, etc): Install a disk of the same size or greater Boot the desktop with the Recovery Disc Point the recovery application at the WHS Pick the machine, the drive(s) and the date of the backup Have a couple beers Reboot to a working machine as if nothing happened. I would need to slap multiple disks in the machine without raid. It sounds like LVM will work here. It would be nice, but not required to have de-duplication of files when multiple machines are backed up. (Single Instance Storage)

• CARP: two machines think they're the master, but only on one interface

  - by Conor McDermottroe

  I have two machines, each configured identically as a firewall/load balancer for a busy website. I have set them up with CARP and pfsync on both the internal and external interfaces. The internal interface is behaving as expected (primary listed as MASTER and secondary listed as BACKUP) On both machines, the network interfaces are as follows: em0 - External interface bge0 - Internal interface bge1 - Crossover connection between both machines carp0 - Shared external interface for CARP carp1 - Shared internal interface for CARP I've rewritten the IP addresses and MAC addresses below. The networks are as follows: 10.0.1.0/24 - External network 10.0.2.0/24 - Internal network 10.0.3.0/24 - Crossover network Here's the output from ifconfig on the primary: em0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=19b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4> ether [SNIP] inet 10.0.1.10 netmask 0xffffff00 broadcast 10.0.1.255 media: Ethernet 100baseTX <full-duplex> status: active bge0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=9b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM> ether [SNIP] inet 10.0.2.10 netmask 0xffffff00 broadcast 10.0.2.255 media: Ethernet 1000baseT <full-duplex> status: active bge1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=9b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM> ether [SNIP] inet 10.0.3.10 netmask 0xffffff00 broadcast 10.0.3.255 media: Ethernet 1000baseT <full-duplex> status: active lo0: flags=80c9<UP,LOOPBACK,RUNNING,NOARP,MULTICAST> metric 0 mtu 16384 options=3<RXCSUM,TXCSUM> inet6 fe80::1%lo0 prefixlen 64 scopeid 0x4 inet6 ::1 prefixlen 128 inet 127.0.0.1 netmask 0xff000000 pflog0: flags=141<UP,RUNNING,PROMISC> metric 0 mtu 33152 pfsync0: flags=0<> metric 0 mtu 1460 pfsync: syncdev: bge1 syncpeer: 10.0.3.11 maxupd: 128 carp0: flags=49<UP,LOOPBACK,RUNNING> metric 0 mtu 1500 inet 10.0.1.5 netmask 0xffffff00 carp: MASTER vhid 1 advbase 1 advskew 0 carp1: flags=49<UP,LOOPBACK,RUNNING> metric 0 mtu 1500 inet 10.0.2.5 netmask 0xffffff00 carp: MASTER vhid 2 advbase 1 advskew 0 And here's the /etc/rc.conf excerpt from the primary: defaultrouter="10.0.1.1" network_interfaces="em0 bge0 bge1 lo0 pfsync0" cloned_interfaces="carp0 carp1" ifconfig_em0="inet 10.0.1.10 netmask 255.255.255.0 media 100BaseTX mediaopt full-duplex" ifconfig_bge0="inet 10.0.2.10 netmask 255.255.255.0 media 1000BaseTX mediaopt full-duplex" ifconfig_bge1="inet 10.0.3.10 netmask 255.255.255.0 media 1000BaseTX mediaopt full-duplex" ifconfig_carp0="vhid 1 pass [SNIP] 10.0.1.5/24" ifconfig_carp1="vhid 2 pass [SNIP] 10.0.2.5/24" pfsync_enable="YES" pfsync_syncdev="bge1" pfsync_syncpeer="10.0.3.11" And here's the output on the secondary: em0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=19b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4> ether [SNIP] inet 10.0.1.11 netmask 0xffffff00 broadcast 10.0.1.255 media: Ethernet 100baseTX <full-duplex> status: active bge0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=9b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM> ether [SNIP] inet 10.0.2.11 netmask 0xffffff00 broadcast 10.0.2.255 media: Ethernet 1000baseT <full-duplex> status: active bge1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=9b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM> ether [SNIP] inet 10.0.3.11 netmask 0xffffff00 broadcast 10.0.3.255 media: Ethernet 1000baseT <full-duplex> status: active lo0: flags=80c9<UP,LOOPBACK,RUNNING,NOARP,MULTICAST> metric 0 mtu 16384 options=3<RXCSUM,TXCSUM> inet6 fe80::1%lo0 prefixlen 64 scopeid 0x4 inet6 ::1 prefixlen 128 inet 127.0.0.1 netmask 0xff000000 pflog0: flags=141<UP,RUNNING,PROMISC> metric 0 mtu 33152 pfsync0: flags=0<> metric 0 mtu 1460 pfsync: syncdev: bge1 syncpeer: 10.0.3.10 maxupd: 128 carp0: flags=49<UP,LOOPBACK,RUNNING> metric 0 mtu 1500 inet 10.0.1.5 netmask 0xffffff00 carp: MASTER vhid 1 advbase 1 advskew 20 carp1: flags=49<UP,LOOPBACK,RUNNING> metric 0 mtu 1500 inet 10.0.2.5 netmask 0xffffff00 carp: BACKUP vhid 2 advbase 1 advskew 20 And here's the /etc/rc.conf excerpt from the secondary: defaultrouter="10.0.1.1" network_interfaces="em0 bge0 bge1 lo0 pfsync0" cloned_interfaces="carp0 carp1" ifconfig_em0="inet 10.0.1.11 netmask 255.255.255.0 media 100BaseTX mediaopt full-duplex" ifconfig_bge0="inet 10.0.2.11 netmask 255.255.255.0 media 1000BaseTX mediaopt full-duplex" ifconfig_bge1="inet 10.0.3.11 netmask 255.255.255.0 media 1000BaseTX mediaopt full-duplex" ifconfig_carp0="vhid 1 pass [SNIP] advskew 20 10.0.1.5/24" ifconfig_carp1="vhid 2 pass [SNIP] advskew 20 10.0.2.5/24" pfsync_enable="YES" pfsync_syncdev="bge1" pfsync_syncpeer="10.0.3.10" What I don't understand is, the carp status on carp0 is MASTER on both machines when the status on carp1 is as it should be (MASTER on the primary and BACKUP on the secondary).

• BootMgr is missing, usual fixes don't work

  - by parsley72

  I know this question has been asked before but I've tried all the usual fixes and nothing works. Basically the hard drive had two partitions with Vista and Windows 7. I've deleted the Vista partition to make more room and expanded the Windows 7 partition to fill the drive (using GParted). I've tried: Running Startup Repair - it doesn't find any problems. Setting partition to Active - worked. bootsect /nt60 c: - worked. BootRec /FixMbr - worked. BootRec /FixBoot - worked. BootRec /ScanOs - I get the message "Total identified Windows installations: 0" BootRec /RebuildBcd - I get the message "Total identified Windows installations: 0" BcdEdit shows a Windows Boot Manager and a Windows Boot Loader, both on C: partition. What else can I try?

• Netinstalling CentOS if the gateway is in a different subnet

  - by James Lawrie

  I have a KVM host (A) running a virtual machine (B). They each have their own external IP address and the networking is setup using bridging between eth0 and br0 on A. B uses eth0, with A being the gateway. The problem is that the two external IP addresses are on different subnets (different /8s in fact) so by default, B claims it cannot reach A (Network Unreachable). I can resolve this by adding a static route on B: echo "any host gateway_ip dev eth0" > /etc/sysconfig/static-routes Modifying /etc/init.d/networking to reload the gateway after applying static routes (I only added the final line before fi): if [ -f /etc/sysconfig/static-routes ]; then grep "^any" /etc/sysconfig/static-routes | while read ignore args ; do /sbin/route add -$args done route add default gw "${GATEWAY}" fi If I then restart networking, it comes online. How can I do this (or work around it some other way) prior to the system being installed, ideally inside an Anaconda kickstart file?

• Crashes and freezes after fixing "BOOTMGR is missing" error

  - by Greg-J

  I came back from a 3-day weekend to a computer that was off. I leave my PC on 24/7, so this was odd. Turn it on to get the dreaded "BOOTMGR is missing" screen. Two attempts at Windows Recovery and it booted into Windows fine. After an hour or so, I get a frozen Chrome and my start bar disappears. Ctrl+Alt+Del brings up an error box telling me that Ctrl+Alt+Del failed to work properly. Clicking on any open application triggers an error (I can't recall the error now, but it essentially just said that the application couldn't be found running or something along those lines). I restart, and again, the same thing happens after a while of use. I turn it on, install the 47 updates I have or so, and then restart it. After a while of use (under an hour), it just freezes completely. My thoughts are: SSDs, RAM or PS. My system specs below: (RAID0) 2 x Crucial M4 CT128M4SSD2 2.5" 128GB SATA III MLC Internal Solid State Drive (SSD) CORSAIR Vengeance 16GB (4 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model CML16GX3M4A1600C9 CORSAIR HX Series HX750 750W ATX12V 2.3 / EPS12V 2.91 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Modular Active 1 x ASUS Maximus IV Gene-Z/GEN3 LGA 1155 Intel Z68 HDMI SATA 6Gb/s USB 3.0 Micro ATX Intel Motherboard 1 x Hitachi GST Deskstar 7K1000.C 0F10383 1TB 7200 RPM SATA 3.0Gb/s 3.5" Internal Hard Drive -Bare Drive 1 x Intel Core i7-2600K Sandy Bridge 3.4GHz (3.8GHz Turbo Boost) LGA 1155 95W Quad-Core Desktop Processor Intel HD Graphics 1 x SAPPHIRE 21197-00-40G Radeon HD 7970 3GB 384-bit GDDR5 PCI Express 3.0 x16 HDCP Ready CrossFireX Support Video Card 1 x Noctua NH-D14 120mm & 140mm SSO CPU Cooler This is all crammed in a pretty small case (NZXT Vulcan) and has been running perfectly problem-free since January. The only thing out of the ordinary is that there is a fan in the case that is now making noise whereas the case has previously been completely silent. I have no reason to believe this is anything more then correlation, but felt it is worth mentioning. I believe it MAY be the SSDs simply because of the BOOTMGR error, but not sure how to test that theory. My belief that it may be the RAM is simply from experience with frozen machines. I haven't had the time to memtest it, but will. The PS being the culprit is something I've picked up by reading similar threads on various forums, and it seems plausible. I am unsure how to test this though. ANY insight whatsover would be greatly appreciated!

• Unable to access Citrix XenApp 6 published applications externally

  - by Christopher McCann

  We are trying to use a trial of Citrix XenApp 6 Fundamentals to virtualise a couple of applications as a proof of concept. We haven't ever used it before so I confess to be a noob with it. We can connect to the XenApp web interface, and the iPad app will connect and list the applications, but the applications themselves will not load. I discovered in the .ica file that it was attempting to connect to the internal IP address of the server instead of its static external. I have been following various threads on Citrix but nothing seems to have fixed it for me. The server is deployed on an EC2 instance with a static elastic IP. All the ports are opened and I can telnet into the XenApp server on 1493 and I get the ICA response. I have also run on ALTADDR and provided the external IP address. Does anyone have any ideas?

• OSX Time Machine: deletion of backup folders

  - by jml

  I saw this question and was hoping that someone could expand upon the chosen answer (which I understood): Can you sudo mv Time Machine backup files as sudo from the trash to their original locations? I have tried doing this as root to no avail (operation not permitted). If not, can you successfully rm them via the trash via the terminal, faster than what the endless 'preparing to empty the trash' dialog suggests, and If you get the files back out of the trash can you tell if they are intact via disk utility (and how) Can you force indexing on a Time Machine drive in the same way that you would a normal drive to rebuild the TM index? I realize that a single answer could clarify all of the above, but I wanted to include details to be clear on what I am asking. Thanks for any help.

• How to check for duplicate files?

  - by miorel

  I have an external hard drive on which I have backed up files several times. Some files were modified between backups, others were not. Some may have been renamed. Now I'm running out of space, and I'd like to clean up duplicate files. My idea was to md5sum every file on the drive, then look for duplicates, and diff the relevant files (just in case, haha). Is this the best way to do this? What are some other methods of checking for duplicate files?

• Does Exchange 2010 lift the restriction that DL addresses must be in Active Directory?

  - by Justin Grant

  We'd like to enable end-users to be able to create and maintain their own email distribution lists in Exchange 2010, where those lists may include users inside the company but also customers, partners, etc. who are outside the company. One of the limitations in Exchange 2007 (see this question) was that any member of a DL had to have an entry in active directory. You couldn't just take a group of email addresses (both inside and outside my company) and create an Exchange DL with those addresses without involving Active Directory admins to create entries for each external user. For a company creating hundreds of small mailing lists every month, this was an unacceptable IT expense. So we had to use a separate mailing list solution (GNU mailman) for DLs which included external users. Is this limitation relaxed in Exchange 2010 so we can throw away GNU mailman and use Exchange instead?

• How can I mitigate DNS Server outages?

  - by Eric Belair

  Let's say I have a root domain of "mysite.com". That domain and its sub-domains have DNS served by an external service - let's call them Setwork Nolutions. If this external company is hit with a DDoS attack, my interally-hosted websites under this domain are no longer accessible at "mysite.com" or "*.mysite.com", even though the website(s) is/are fully up and operational. How can I mitigate such a problem so as to keep end users happy? The only solution others at my company have come up with is to create a second domain - i.e. "mysite2.com", and host its DNS at another company, and then communicate to all end users that this is the website they should use. I think this is ridiculous, and just leads to a bunch of other problems. I'd like to find a solution where we can point to the same website with the same URL without the original DNS host being operational. Any thoughts?

• Simple Workstation Imaging Solution?

  - by Will

  Hey guys, I need a fairly cheap imaging solution for Windows XP corporate desktops. Ideally, I'd be able to set up a desktop exactly as we want it, create an image, deploy this image to a server, then boot a new desktop to a CD/USB Drive/Network and quickly set up the workstation. Ideally, each computer would also have a unique workstation name. Any ideas? Right now I'm using a custom built Linux DD solution, but it's slow, not network-based, can't image multiple computers at the same time as there's only one copy on a USB drive, and can't uniquely name the computers. Thanks, Will

• Unmount Mass Storage USB Device from the Command Line in Linux

  I've searched high and low, and can't figure this one out. I have a older Olympus Camera (2001 or so). When I plug in the USB connection, I get the following log output: $ dmesg | grep sd [20047.625076] sd 21:0:0:0: Attached scsi generic sg7 type 0 [20047.627922] sd 21:0:0:0: [sdg] Attached SCSI removable disk Secondly, the drive is not mounted in the FS, but when I run gphoto2 I get the following error: $ gphoto2 --list-config *** Error *** An error occurred in the io-library ('Could not lock the device'): Camera is already in use. *** Error (-60: 'Could not lock the device') *** What command will unmount the drive. For example in Nautilus, I can right click and select "Safely Remove Device". After doing that, the /dev/sg7 and /dev/sdg devices are removed. Some things I've tried already are sdparm and sg3_utils, however I am unfamiliar with them, so it's possible I just didn't find the right command.
