• Detect damage done by virus

  - by user38471

  Hey, this morning after I went to college a virus infected my pc without any user interaction at my end. When I came home my computer was completely frozen and infected with lots of trojans. I have not typed anything important since returning so keys cannot be logged. However I want to know exactly when my computer crashed from the time of infection to see what could potentially be done remotely by a hacker. The virus my pc was diagonosed with was "fakespypro" http://www.microsoft.com/security/portal/Threat/Encyclopedia/Entry.aspx?Name=Win32%2fFakeSpypro on a fully updated windows 7 installation with firewall enabled. My computer was connected to an internal dorm room network, so probably that has had to do something with it. Any further information about how I could backtrace this virus infection or ways to discover what data might be stolen would be greatly appriciated.

• Unable to logoff, disconnect, or reset terminal server user in production environment

  - by l0c0b0x

  I'm looking for some ideas on how to disconnect, logoff, or reset a user's session in a 2008 Terminal Server (unable to login as the user either as it is completely locked-up). This is a production environment, so rebooting the server or doing something system-wide is out of the question for now. Any Powershell tricks to help us with this? We've tried to disconnect, log the user off and reset the session as well as killing the session's processes too, directly from the same terminal server (from the task manager, Terminal Services Manager and the Resource Monitor) with no results. Help! UPDATE: We ended up rebooting the server as no other attempts that we could think of worked. I'll leave this question open hoping someone might have more information about this one issue, and it's potential fixes

• Does ILOM on recent Sun rackmount servers fully support Linux?

  - by orange80

  Do the recent Sun rackmount servers with ILOM fully support installation of Linux (Ubuntu or Fedora maybe) via the ILOM (connected by ssh) without having to hook up a display, kbd, and mouse? I have an old Sun v20z right now that will install Solaris no problem over the Service Processor but when trying to install Ubuntu 9 64-bit server I get one line on the console then it goes blank. I'd be interested in know which if any of the recent x64 models would allow me to install and run linux while completely avoiding any need for external display, keyboard, or mouse. Thanks!

• Windows 7 Wakeup from Sleep then Shutdown

  - by Kevin Hua

  Is this caused by low battery? I have an Asus UX31A, and I left it unattended. As usual, in 5 minutes, it went to sleep mode with the lid still open. I came back a couple hours later, and I noticed the laptop was off. I was still able to turn it on by manually pressing the power button (battery was at 2% though), but I don't understand why it shut off. If it was in sleep mode and the battery was near depletion, then wouldn't that result in a "Windows has recovered from an unexpected shutdown" upon boot? Does Windows have a mechanism to wake from sleep from a super critical battery level to shut down all programs and power down the system completely? I noticed that upon booting, firefox didn't give a fit about improper shutdown. Here are my power settings btw, powercfg -h off has been ran, so hibernation is off. And here is the event log: http://www.mediafire.com/download.php?lbfhl21g0nj2adi

• WBAdmin SystemState Problems

  - by TheD

  I recently installed DHCP on my 2008R2 Server and now Backup Exec and WBAdmin/WSB is having System State issues. Essentially, after some research, I came across a handy tool called VSHADOW which has allowed me to output all the files (and their respective directories) to a text file. And hooray, I think I found the problem: * WRITER "Dhcp Jet Writer" - WriterId = {be9ac81e-3619-421f-920f-4c6fea9e93ad} - InstanceId = {0ed0a8f4-19b0-414d-a3a8-d51d6f4ac8e0} - Supports restore events = TRUE - Writer restore conditions = VSS_WRE_IF_REPLACE_FAILS - Restore method = VSS_RME_RESTORE_AT_REBOOT - Requires reboot after restore = TRUE - Excluded files: - Component "Dhcp Jet Writer:\C:_Windows_system32_dhcp\dhcp" - Name: 'dhcp' - Logical Path: 'C:_Windows_system32_dhcp' - Full Path: '\C:_Windows_system32_dhcp\dhcp' The logical path and Full Path for DHCP is completely wrong. However I can't find where I would change this path, I assume in the registry but I've had no luck finding the key !

• BIOS root kit? Or, how do I fresh install a clean BIOS?

  - by Leopold_Bloom

  So I was installing questionable operating system onto my EEE pc and it required me to downgrade the BIOS which I really am not an expert at. I used a patch and it appeared to work. Now, I'm paranoid about the downgrade because, honestly, I have no idea where the code came from or what could be in it. My question, then, is it possible to "start over" completely fresh with my BIOS? As in wipe out the possibly malicious BIOS and go back to the manufacturer-provided one? Has anyone done something similar to this? I just want to install Ubuntu Netbook Remix to the EEE pc 1000 but I want to make sure the BIOS are secure. Any advice would help tremendously, or am I just being uber paranoid? BIOS are definitely not my strength.

• One-Way Backup Service? [closed]

  - by Jon Rodriguez

  Up until a month ago, my girlfriend has used MobileMe to backup all the files on her MacBook. This turned out terribly when a quirk of MobileMe caused it to erase all of her files on MobileMe, and then sync the newly-erased MobileMe down to her computer, erasing everything. A week's worth of college essays and CS homework were gone. Now, I am terrified of any commercial cloud-backup solutions because of the possibility of this happening. Going off the list provided in these answers, could you please help me find a good backup service that is completely one-way? I want a service where there is literally not a single line of code that has the possibility of writing to my computer's drive. I want a pure one-way backup service.

• How to keep Varnish cached populate after backend down for an extended period?

  - by Nicholas Tolley Cottrell

  We have Varnish 3.0.2 running on Amazon's Linux and it works great. We have a ttl of 48 hours for most content pages and much longer for images, PDFs etc. This weekend we've taken the backend down for some maintenance, so I upped the ttl to 5 days earlier in the week. I had assumed that anything in cache would continue to be served for up to 5 days, but much to our disappointment we checked varnishstat this morning and the cache was almost completely empty and varnish was serving "page not found" messages. I know that this is not what Varnish is designed to do, but why would it reset its cache when the backend is down? And how can I prevent it for next time?

• How can I set up conditional formatting to highlight a range only if all its cells are empty?

  - by Jennifer

  I am new to conditional formatting and having a hard time. I have 6 columns with 100 rows. What I would like to have happen is to highlight the row in one color if there is no data in it at all. If there is data in one cell within the row, however, I would like for the highlighting to be removed from the row completely. Currently I have it set up to highlight the entire row if there is no data in it and if there is data in one cell, only that cell has no highlighting....I can't seem to make the entire row's highlighting disappear. I have used the formula to determine which cells to format: =I16:N16="" formatting color is yellow. I know I have to add a second conditional format but I have tried numerous different formulas and cant seem to get it to work.

• Windows 7 Recurring Blue Screens: MEMORY_MANAGEMENT 0x1A

  - by Chris C.

  I have recurring BSODs that really have me scratching my head. Here's a look at the errors: MEMORY_MANAGEMENT 0x1A (ntoskrnl.exe) - I've seen this 9 times since April 2012 NTFS_FILE_SYSTEM 0x24 (Ntfs.sys) - this one's new, happend 4 days ago BAD_POOL_HEADER 0x19 (win32k.sys) - also new, happened 7 days ago My system specs: Intel Core i5 2500K @ 3.30GHz ASUS Sabertooth P67 Motherboard (Rev 2) * RMA'd my Rev 1 due to recall 16GB (4 x 4GB) Kingston HyperX 1600 MHz DDR3 RAM 2 x 640GB Western Digital Caviar Black 64MB SATA HDD EVGA NVIDIA GeForce GTS450 1GB PCI-E 2.0 Graphics Card I've got Windows 7 Home Premium and it's completely patched. I'm also running Microsoft Security Essentials, which is up-to-date and always present. I've run MemTest86+ from a USB drive for up to nine hours, giving my RAM a total of 6 passes, and it didn't detect a single error. I've used chkdsk in Windows 7 to scan the C:/ drive on boot (twice) and it found no problems. How can I find out what's causing all these blue screens?

• Source of Unexplained Requests in Server Logs

  - by Synetech inc.

  Hi, I am baffled by some entries in my server logs, specifically the web-server logs. Other than normal, expected traffic, I have noticed three types of request errors (eg 404, etc.): Broken links, ie links from old, external pages that point to pages that are no longer here Sequences of probes, ie some jerk trying to hack in by scanning my server for a series of exploitable admin type pages and such What appear to be completely random requests for things that have never existed on the server or even have anything to do with the server, and appear by themselves (ie not a series of requests like the probes) Could it somehow be a mistyped URL or IP? That’s about the only thing that I can think of, but still, how could I get a request on say, foobar.dyndns.org (12.34.56.78) for something like www.wantsfly.com/prx2.php or /MNG/LIVE or http://ant.dsabuse.com/abc.php?auth=45V456b09m&strPassword=X%5BMTR__CBZ%40VA&nLoginId=43. (Those are a few actual requests from my logs.) Can someone please explain scenario three to me? Thanks.

• How to resize the disk of a Fedora guest VM in VMWare ESXi

  - by Cerin

  How do I resize (specifically increase) the disk size of a Fedora guest VM running under VMWare ESXi 4.1? I have a Fedora 16 VM with an ext4 formatted disk, and I've increased its disk size using the vSphere client from 50GB to about 250GB. I rebooted the guest, and it correctly shows this size using fdisk -l /dev/sda. However, df -H still shows the old size. I've found a few KB articles explaining how to resize partitions for some flavors of Linux, but nothing for Fedora with ext4. That article seems to imply I have to create a completely new partition, and that I can't simply expand the existing partition. Using Gparted, it also prevents me from simply resizing the existing partition. Is this impossible to do under Linux?

• How can I get Gnome-Do to open in multiple X Screens?

  - by btelles

  Hi, I LOVE Gnome-Do (the Ubuntu version of QuickSilver). The only thing is that I have several monitors, which are all completely separate X Screens (I.E. I can't move windows between them), and Gnome-Do will only open in ONE of those monitors. If I go to Monitor/Screen #2 and press Super+Space, the Gnome-Do window appears in the first monitor. Is it possible to get a separate Instance of Gnome-Do on each Screen? P.S. Using profiles may be a work-around...I've managed to get multiple instances of Firefox by using "firefox -P my_first_screen"...anything like that available in Gnome-do?

• How does MySQL 5.5 and InnoDB on Linux use RAM?

  - by Loren

  Does MySQL 5.5 InnoDB keep indexes in memory and tables on disk? Does it ever do it's own in-memory caching of part or whole tables? Or does it completely rely on the OS page cache (I'm guessing that it does since Facebook's SSD cache that was built for MySQL was done at the OS-level: https://github.com/facebook/flashcache/)? Does Linux by default use all of the available RAM for the page cache? So if RAM size exceeds table size + memory used by processes, then when MySQL server starts and reads the whole table for the first time it will be from disk, and from that point on the whole table is in RAM? So using Alchemy Database (SQL on top of Redis, everything always in RAM: http://code.google.com/p/alchemydatabase/) shouldn't be much faster than MySQL, given the same size RAM and database?

• How do i mitigate DDOS attacks on static servers?

  - by acidzombie24

  Here is a slightly different take on DDOS attacks. Rather than a server with dynamic content being attack i was curious how to deal with attacks on servers with STATIC CONTENT. This means cpu tends to not be an issue. Its either bandwidth or connection problems. How would i mitigate a DDOS attack knowing nothing about the attacker (for example country, ip address or anything else). I was wondering is shorting the timeout and increasing amount of connections is an acceptable solution? Or maybe that is completely useless? Also i would limit the amount of connections per IP address. Would the above help or be pointless? Keeping in mind everything is static checking for multiple request of the same page (html, css, js, etc) could be a sign of a attack. What are some measures i can take on a static content server?

• Apache Rewrite Rules breaking each other?

  - by neezer

  I have this rule: RewriteCond %{REQUEST_URI} ^/(manhattan|queens|westchester|new-jersey|bronx|brooklyn)-apartments/.*$ RewriteCond %{REQUEST_URI} !^/guide/(.*)$ RewriteRule ^(.*)$ /home/neezer/public-html/domain.com/guide/$1 [L] Which works great on it's own. Essentially, I have a bunch of directories that have a bunch of files in them that I want to keep in the "/guide" folder, but I want them to appear at the web root for SEO reasons. This rule works, but unfortunately the original URL's still work too (with "/guide"). I want to 301 Redirect the ones with "/guide" in the URL to those without, without actually moving the files on the server. I tried adding this rule: RewriteCond %{REQUEST_URI} ^/guide/(manhattan|queens|westchester|new-jersey|bronx|brooklyn)-apartments/.*$ RewriteRule ^guide/(.*)$ http://www.domain.com/$1 [R=301,L] ... but that breaks my first rule completely. Any thoughts about what I might be doing wrong? Please let me know if you need to know anything else from me to help me with this issue.

• Can't ping self

  - by Paddy

  I have a wireless internet connection setup on my Mac. (v10.5.6) Am connected to the internet and everything is running smoothly. I recently discovered a quirky behaviour while setting up apache web server. When i typed in my dynamic ip (http://117.254.149.11/) in the webbrowser to visit my site pages it just timed out. In terminal i tried pinging localhost and it worked. $ ping localhost PING localhost (127.0.0.1): 56 data bytes 64 bytes from 127.0.0.1: icmp_seq=0 ttl=64 time=0.063 ms 64 bytes from 127.0.0.1: icmp_seq=1 ttl=64 time=0.056 ms 64 bytes from 127.0.0.1: icmp_seq=2 ttl=64 time=0.044 ms But if i pinged my ip it would just time out. $ ping 117.254.149.11 PING 117.254.149.11 (117.254.149.11): 56 data bytes ^C --- 117.254.149.11 ping statistics --- 10 packets transmitted, 0 packets received, 100% packet loss Pinging any other site works though. I am completely stumped. Any help would be greatly appreciated.

• EMC CX3-10c Fault Condition won;t clear

  - by ITGuy24

  We have an old CX3-10c from Dell that had both Standby Power Supplies (SPS) fail. This obviously caused a fault on the system and disabled the cache. We have replaced the SPS's and they test fine as do all other components. Problem is there is still a fault on the "Enclosure SPE [SPE3]" despite all the component in the enclosure showing as good. I was on the line with Dell Gold support for 3 hours yesterday, they have had me restart the SPs multiple times, as well as reseat the power supplies, even shutdown the system completely and power it back on. All to no avail. Fault remains and cache cannot be re-enabled so long as the Fault is present. Any suggestions on clearing this erroneous fault?

• How to reassign drive back into MediaShield (nvidia) RAID stripe

  - by scottwed

  So I managed to inadvertently remove the RAID configuration from 1 drive of a 2 drive stripe. I have both drives, unmodified, and undamaged. Specifically for MediaShield RAID, is there any way to reattach the 2nd drive back into the stripe? Current state is the stripe is displayed in Error status, and I have the other drive available, but unassigned. I strongly suspect there is no solution without purging the array completely and redefining the stripe, but I figured it was worth asking before I wipe out the data.

• Cannot boot from a hard drive

  - by Martin Melka

  I have a problem booting from a hdd. I used to have it as my main drive before I bought an SSD, so I had been able to boot from it. But for some reason, now, half a year later, I can't get it to work. I completely erased it, deleting data and partitioning (using EASEUS Partition Master), then I installed Kubuntu (without changing anything in the installer), but it simply won't boot up. It always boots the drive with Windows and when I unplug this drive, it only gives me an error "PXE-E61: Media test failure, check cable", I guess it's trying to boot from LAN. I tried installing the system on a freshly deleted drive, without any other drives plugged in the pc, but the problems persist. This is how the drives look now (first one has Windows 7 installed, the second one Kubuntu): I am lost. I mean, after doing a fresh wipe and a clean install without altering anything, it should work. But it doesn't. What can be wrong here? Thanks

• Longlasting Macport installation

  - by user10826

  Hi, I use Macports on Mac OSX to install some software. But there are somethings that I find very strange. For instance, yesterday I installed some app. and the it needed to get gcc43 and compile completely from source! It took a lot of time, although now everything works right. I understand that compilation of everything in the gentoo spirit is eomthing nice, but in the Mac case, not necessary. There are ony sole hardware variations, so it will be easier to get the binaries. I wonder if Macporst can be forced to get the binaries when available and therefore avoid these time consuming compilations. Thanks

• Switching to LDAP over SSL for Active Directory

  - by bkildow

  On our active directory server, I would like to enable LDAP over SSL as per this: http://support.microsoft.com/kb/321051. I am wondering, once this is set up, will LDAP still be listening on the standard port, 389 once this is implemented as well as the secure port? Or will the secure port completely replace the standard port as an option to connect to? Also, will there need to be any other configurations besides the steps in the article for doing this? In other words, will domain users still be able to authenticate like normal, or is there additional setup that would need to occur?

• Laptop overheating within minutes of start up

  - by Spik330

  I have a Dell Windows 7 Home Prem with an I7-720QM. More information on the computer can be found here http://www.dell.com/support/home/us/en/04/product-support/servicetag/51CVCN1/configuration The Problem I am having is the computer will over heat unnaturally fast. From the time it takes from boot to when i can run my diagnostic tools which takes about two minutes the cpu temp is 86c after a few more minutes the cpu temp will reach 100 and the computer will black screen shut down. In total the the laptop can only be run for 3-5 minutes before completely shutting off. During this time there is nothing extensive running. After the laptop shuts down you have to wait for it to cool down or it will shut off even faster sometimes 7-15 seconds well still in the boot screen. Does anyone know what could be the problem maybe a sensor or is the computer fried?

I know almost nothing about apache nor how to use it and nearly all the article say write this but doesnt tell me where. So far i have done this # a2enmod deflate Module deflate already enabled Then i tried writing this in httpd.conf AddOutputFilterByType DEFLATE text/html text/plain text/xml text/css Then i wrote a longer version which involved deflate.c. After those didnt work i deleted them all and wrote the AddOutputFilterByType line in apache2/sites-enabled/000-default inside of I used this to test http://www.whatsmyip.org/http_compression/ everytime it says no compression. I used another site but i could never compress. Also i restart the server everytime i save a file so what could be the problem and how do i enable this properly?

• Technicolor TG582n with external DHCP server [on hold]

  - by Jack

  We have a small home setup with a Technicolor TG582n on Plusnet ISP. We have a Samba4 DC with DNS forwarding enabled. The DC forwards to the Technicolor. However, the client machines have their DNS settings manually set. This is an annoyance when using laptops on other networks. We would like to have DHCP handled on the server machine, such that when a client connects to the Technicolor, it gets its IP and DNS information from the DHCP server, eliminating the need to manually set adapter DNS settings. However, I cannot find an option to disable DHCP on the Technicolor and am not completely clear on how one would point DHCP services to the server from the Technicolor if there were the option. So, how would one make the Technicolor use an external server for DHCP leases?
