• How to ignore an error in Powershell and let it continue?

  - by Jake

  I am trying to see if a process is running on multiple servers and then format it into a table. get-process -ComputerName server1,server2,server3 -name explorer | Select-Object processname,machinename Thats the easy part - When the process does not exist or if the server is unavailable, powershell outputs a big ugly error, messes up the the table and doesn't continue. Example Get-Process : Couldn't connect to remote machine.At line:1 char:12 + get-process <<<< -ComputerName server1,server2,server3 -name explorer | format-table processname,machinename + CategoryInfo : NotSpecified: (:) [Get-Process], InvalidOperatio nException + FullyQualifiedErrorId : System.InvalidOperationException,Microsoft.Power Shell.Commands.GetProcessCommand How do I get around this? If the I would still like to get notified if the process isn't available or Running.

• Inexpensive degaussers or HDD shredders?

  - by Nicholas Knight

  I do a lot of work for a small cash-strapped business that has a lot of active hard drives, most are consumer-grade SATA of about five years of age, and predictably they are dying at an increasing rate, and a lot of the time they can't even be detected, let alone complete a zero-out cycle. Right now those drives are just being stored, but that can't continue forever. We've got a couple bad LTO tapes it'd be nice to deal with, too. There are very real security and legal issues that make dropping them off with someone who claims they'll be properly destroyed a gamble. I've looked around at degaussers and HDD shredders, and the ones that don't look like they come from some guy in his basement all seem to be $3000+, which is hard to swallow right now. Is there anything out there in the $500-1500 range that you would recommend? (Speed isn't a big issue, if it takes several minutes or even hours per drive, that's completely OK, we've only got 10 or so thus far.)

• Why won't IE let users login to a website unless in In Private mode?

  - by Richard Fawcett

  I'm not entirely sure this belongs on SuperUser.com. I also considered ServerFault.com and StackOverflow.com, but on balance, I think it should belong here? We host a website which has the same code responding to multiple domain names. On 28th December (without any changes deployed to the website) a percentage of users suddenly could not login, and the blank login page was just rendered again even when the correct credentials were entered. The issue is still ongoing. After remote controlling an affected user's PC, we've found the following: The issue affects Internet Explorer 9. The user can login from the same machine on Chrome. The user can login from an In Private browser session using IE9. The user can login if the website is added to the Trusted Sites security zone. The user can NOT login from an IE session in safe mode (started with iexplore -extoff). Only one hostname that the website responds to prevents login, the same user account on the other hostname works fine (note that this is identical code and database running server side), even though that site is not in trusted sites zone. Series of HTTP requests in the failure case: GET request to protected page, returns a 302 FOUND response to login page. GET request to login page. POST to login page, containing credentials, returns redirect to protected page. GET request to protected page... for some reason auth fails and browser is redirected to login page, as in step 1. Other information: Operating system is Windows 7 Ultimate Edition. AV system is AVG Internet Security 2012. I can think of lots of things that could be going wrong, but in every case, one of the findings above is incompatible with the theory. Any ideas what is causing login to fail? Update 06-Jan-2012 Enhanced logging has shown that the .ASPXAUTH cookie is being set in step 3. Its expiry date is 28 days in the future, its path is /, the domain is mysite.com, and its value is an encrypted forms ticket, as expected. However, the cookie is not being received by the web server during step 4. Other cookies are being presented to the server during step 4, it's just this one that is missing. I've seen that cookies are usually set with a domain starting with a period, but mine isn't. Should it be .mysite.com instead of mysite.com? However, if this was wrong, it would presumably affect all users?

• Security of a free public VPN service

  - by Mark Belli

  I just started using VPNBOOK, which is a (very efficent) free VPN solution. I have a question: VPNBOOK user and pass used to connect to their vpn network are publicily available on their homepage; everybody uses them to connect to the vpn. Can a user intercept my wifi traffic and: Understand that my connections are directed to VPNBOOK servers. If point 1 is successful, then they could use VPNBOOK public user and pass to decrypt my traffic? I hope I am missing something, otherwise it would be a very big weakness and I would revert to a paid service (with a private account)

• Areca 1880ix RAID hangs

  - by Dave

  Areca RAID controller ARC-1880ix-12 (firmware 1.50) hangs when on high load. My setup is: Chenbro 3U chassis Intel S5500BC mainboard Xeon 5603 CPU 16GB of RAM 12 Seagate SAS drives ST32000645SS (2 of them as hot spare, 10 as RAID10) Mellanox Infiniband HBA card This server is working as external infiniband storage for Xen VMs. When load is quite big Areca's firmware hangs - it becomes unreachable even from Areca's ethernet adapter. After resetting the server power it returns to normal operation. While Areca is hanged I can confirm that it is powered (ethernet link is active) and Infiniband HBA works Ok. Thanks in advance for any idea or suggestion where the problem might be!

• Is SSL to the proxy good enough?

  - by Josh Smeaton

  We are currently trying to decide on how best to do SSL traffic in our environment. We have an externally facing Apache proxy server that is responsible for directing all traffic into our environment. It is also doing the SSL work for the majority of our servers. There are one or two IIS servers in particular that are doing their own SSL, but they are also behind the proxy. I'm wondering, is SSL to the proxy good enough? It would mean that traffic within our network is identifiable, but is that such a big deal?

• When upgrading from Vista to Windows 7 on a DELL laptop, how do I know which drivers to reinstall an

  - by msorens

  According to Dell's upgrade page for Vista to Windows 7, after using the upgrade assistant the final step is to install drivers. They refer to this page for the order of driver installation, listing 9 items. From there I go to the Dell Drivers and Downloads page, enter my system tag, and get a list of the downloads available for my specific box. That page, by the way, has a link to driver install instructions that lists 10 rather than 9 items. Going to Drivers Help in the side panel and clicking on "In what order should drivers be installed?" shows yet a third list, this one containing 13 items. Not surprisingly, the order of these 3 lists of drivers are not quite the same for the common items! Furthermore, of the 26 files Dell's site recommends for my machine, there are several not shown on any of the 3 lists! I can make determinations for some of these: 6 of them are "applications" so I know which of those I want and that they could probably be safely installed after all drivers. BIOS: I would think this should be unaffected by an OS upgrade so could be skipped. Two tools in the diagnostics category: could probably be done after all drivers. That leaves just a CD/DVD driver and a webcam driver unaccounted for. So my two related questions are these: How critical is the driver installation order and which one do I follow? (Keep in mind this is for an upgrade, not a fresh install.) Where in the order do I insert the CD/DVD and the webcam drivers (if needed) ? Dell's driver download page provides (in theory) the list of all downloads relevant to my specific machine, via the service tag. But do I actually need to reinstall all of them? some? none? How does one determine this? They do label each with Recommended or Optional, so do I need to reinstall all the recommended ones? (Part of the reason for my perplexed frown is that I wonder why I would need to reinstall a CD/DVD driver since I would already be using the drive to install the OS!)

• What are the best possible ways to benchmark RAM (no-ECC) under linux / arm?

  - by moul

  I want to test integrity and global performances of no-ECC memory chips on a custom board Are there some tools that run under linux so I can monitor system and global temperature in the same time ? Are there some no-ECC specific tests to do in general ? EDIT 1: I already know how to monitor temperature (I use a special platform feature /sys/devices/platform/......../temp1_input). For now : wazoox : it works but I've to code my own tests Jason Huntley : ramspeed : does not work on arm stream benchmark : it works and is very fast, so I'll look if it's accurate and complete memtest : I'll try later, since it does not run directly from linux stress for fedora : I'll try later too, it's too problematic for me to install fedora now I found this distribution : http://www.stresslinux.org/sl/ I'll continue to check tools that run directly under linux without too big dependencies, after I'll maybe give a try to solutions like stresslinux, memtest, stress for fedora. Thanks for you answers, I'll continue to investigate

• Uninstalled Ubuntu, no GRLDR?

  - by user32965

  So I'm a big fat idiot. I installed Ubuntu 11.04 on my school's laptop, and here's come the time that I have to turn it back in. I wrote GRUB to the Master Boot Record, thinking it wasn't going to be permanent. So, fast forward to yesterday. I decided to hell with this, and popped in my Windows 7 CD, deleted the whole partition, formatted to NTFS, and installed Windows 7 on it. I'm surfing the web and my computer overheats [totally typical] I boot up, and get this: Try (hd0,0): FAT32: No GRLDR Try (hd0,1): invalid or null Try (hd0,2): invalid or null Try (hd0,3): invalid or null Try (hd1,0): NTFS5: No grldr Try (hd1,1): invalid or null Try (hd1,2): invalid or null Try (hd1,3): invalid or null Cannot find GRLDR. Press space bar to hold the screen, any other key to boot previous MBR... Timeout: 5 The timeout part just counts down to 0 from 5. I need to turn in this thing before tomorrow, please please please can someone help me out?

• Shared storage for web cluster

  - by user52475

  Hi all! Have a big question about shared/clustered/distributed file system for storage. It will shared storage for shared web hosting (web files + maildir) and OpenVZ containers storage . Have any one working example of such system? The options are: Lustre GFS1/GFS2 - GFS2 - as I understand is EXPERIMENTAL... NFS This 3 systems which I consider for shared storage. Now I have storage with HW RAID 10 - 1TB. NFS - As I know there will be problem with locking? GFS/Lustre - problems when there will be a lot of small files , what is typical for hosting environment and problems with maildir.

• HTTP Caching Server that supports POST

  - by Jeroen

  I am hosting a REST service which is sending appropriate cache-control headers. I use Varnish as a caching server in front of my webserver. However, a limitation of varnish is that it doesn't support caching HTTP POST and HTTP PUT. Is there any alternate caching server that will be able to cache these requests? I understand that caching POST is a bit tricky because you cannot just cache based on the url as a key like for GET; it needs to actually inspect the request body. In case of multipart/form-data requests, there should probably be a limit on the size of the request body for it to be cached (so that big file uploads, etc won't be cached). Nevertheless I really want to be able to cache short HTTP POST, or at least the application/x-www-form-urlencoded ones.

• How to delete system default printer forms?

  - by matt wilkie

  On Windows there are system default printer forms which can't be deleted from the Print Server Properties dialog. Is there some other way they can be removed? We are never going to use page sizes like Envelope, B5(JIS), US Std Fanfold, etc. and I'd like to save users (and myself!) from having to scroll through a big long list of noise. Our print servers are Windows Server 2003 if that makes any difference. thanks.

• Copying files from Public folder to C: takes a minute, even though they are same hard drive and same

  - by Jian Lin

  I have a big file, like 2GB, and would like to copy it from Network -> Bookroom -> Users -> Public (this is the computer in the bookroom in the house) to c:\myfiles and they are actually on the SAME hard drive (and same partition). But copying still takes a minute or so? I thought if on the same hard drive and partition, then it is a "move" and it should take 2, 3 seconds only. that public folder also is \\Bookroom\Users\Public

• Shared storage solution for our sql server backups

  - by Gokhan

  We have 3 clustered sql servers. We have 5+ multi terrabyte databases and their backup files (compressed using quest litespeed) are hitting over 600gb each, We are required to keep at least a week or two weeks (if we can) of weekly full backups and then 6 days differential backups, and a week or 2 weeks worth of log backups local. We are currently limited to 2TB volumes from our san team, we can have multiple volumes but they are expensive ($200 per raw TB per month) and having to deal with many backup volumes instead of a single big volume is difficult. I think if we could have a shared network storage of 20TB+ raid 10 or so for all our servers for keeping the backups and another department will copy them to tape from the network storage and delete files according to the retention period would be good, if this box would be a build in operating system (even unix a complete file storage system) that would be good. What do you guys think, does this make sense to you, is there any manufacturer that sells a storage product like that which that work in a clustered environment? Thank you

• Disable page cache on a specific page

  - by David Brunelle

  Hi, Not sure if I really am on the right forum, but if not, just tell me. I have a page that is coded in ASP (not .net) which is used to send email. We are currently having a problem in which the page seem to be sent twice sometime. Upon checking, we found out that those who have this problem are coming from big organisation, so it was suggested that their server might cache the file for some reason. I would like to know, is there a way in HTML (or ASP ) to prevent that from happening ? Or is it in IIS that we must set this up ? Thanks,

• Generate metadata of all files in a dir?

  - by nmuntz

  We are working on a project that is quite big, and its stored in an SVN repository under different folders with many files all over the place. Quite often, it is hard to locate the document that has a certain keyword or phrase. Does anyone know of any program that will generate and index the metadata of all the files that are in these documentation folders? (most filetypes are: xls, doc, ppt). Windows Search and Google Desktop could be an option but that would generally index the whole hard drive, emails, etc and thats probably much more than what we need and would not be suited for something more folder specific. Example of what im looking for: a program or webpage where i enter "John Doe" and it will show me all files in MyProjectFolder/ that contain the keyword "John Doe". This of course will already be indexed somewhere so searches should be almost instantaneous. Is there such a tool or i am asking too much? Thanks in advance!

• Saving Photoshop workspace doesn't remember docked panel state

  - by johnh

  A friend of mine has recently setup his computer with a fresh install of Windows 7 and Photoshop CS5. He's having a strange issue with saved workspaces not remembering the state of docked panels. As an example, he's docked several panels on the right of the screen. The Layers panel is docked but is open, showing all layers in the document. If he saves this as a workspace, closes and reopens Photoshop and loads the workspace, the Layers panel is docked but is closed. It's not the only panel this is happening with. It's not a big problem but he's having to open 4 panels and drag them to the appropriate height each time he starts Photoshop. Does anyone know of a possible fix for this? Any insight would be great.

• What happens if an OpenStack cloud controller dies?

  - by magu

  I've been reading up on OpenStack and how we can re-create an EC2/S3-style cloud for our internal development and I'm having a hard time finding information on how the OpenStack cloud controller provides redundancy of the cloud management services. I know I can setup multiple Swift and Nova nodes, but not a single document/article/howto/wiki contains information on: a) what happens if the cloud controller node dies; and b) how to setup redundant cloud controllers. It seems to me that, although it is massively scalable, there is a big single-point-of-failure built into OpenStack. Can anyone with more experience on OpenStack please shed some light as to how it all works in regards to high-availability?

• Can I make a computer connecting via VPN visible to computers within the network it is connecting to

  - by SCdF

  OK, here's the deal: I have a computer (specifically, a MacBook Pro) that is connected to a standard network that is then connected to the big nasty internet. Let's call it foo. It runs a web server on 8084, and so if you were on its local network you could get to this with http://foo:8084/, or http://192.168.1.2:8084/, or whatever. From foo I can VPN into my companies intranet and see a computer on the local company network called bar (another MacBook Pro, incidentally). Is there any way to set this up so that while foo is on the VPN bar can access http://foo:8084/ (or http://x.x.x.x:8084/, or whatever)? (From my limited understanding of how VPNs work I have a sneaking suspicion the answer is no, but it doesn't hurt to ask...)

• Is there a RAR extractor (for multiple rar files like .r00 etc.) that will use all of my quad cores?

  - by Christopher Done

  I've got a quad core Intel processor. I've got a big file split into little ones as RAR files, foo.r00, foo.r01, etc. which the RAR program extracts into one file/directory. Is there a RAR program that I can specify like "use four cores" in the extract process? At the moment it sits there using 100% of one core. I recognise the bottleneck might be my hard drive anyway, but I don't see a lot of HD usage and suspect the decompression process is more intensive than waiting on I/O. For example, GNU Make accepts a (-j, I think) argument to tell it how many cores to use, which I used to compile PHP 6 really quickly.

• no UAC prompt when opening the Services applet

  - by Serge - appTranslator

  Not quite sure if this question is better asked here or on superuser.com Hi All, My Win7 Ultimate no longer 'UAC prompts' me when I open the services applet (administrative tools). I can manipulate services without ever confirming the elevation. Yes, UAC is still enabled. Yes, I've rebooted to make sure this is not due to a former UAC elevation of explorer.exe or so. It looks like a big security hole. Does anyone have an idea about the reason for this behaviour? Or how to investigate it? TIA,

• Files slow to save sometimes after Ubuntu upgrade

  - by Matchu

  I haven't quite been able to track down why this happens sometimes in Ubuntu 10.04 and not other times. I'll go into gedit or OpenOffice.org and try to save files, and, during some sessions, it will take up to 10 seconds to save the file, sometimes causing the program to become unresponsive. But during these same sessions, the files sometimes save instantly. This didn't start happening until after the 10.04 (Lucid) upgrade. I suspect that something is reading all the changes I make, or that there's some other big file action going on, or something like that. I disabled Tracker a while back, before the upgrade, and don't see it under the settings - could it be back under a different name under Lucid? You probably don't already know the answer, but how can I go about finding the cause of this problem?

• How does Windows handle Time? Updating RTC, etc. (Active Directory and Novell E-Directory)

  - by bshacklett

  I'm troubleshooting some time issues in my domain and before making any big changes I want to have a thorough understanding of what's going on. I've got a few lingering questions at the moment: What sources (rtc, ntp, etc.) are queried by Windows to keep time? How does this differ in a mixed Active Directory / Novell environment? What is the order that each source is queried in? How does Windows decide whether to act as an NTP client, peer or server? In what situations will Windows update the RTC, if ever?

• Is SmoothWall a good firewall alternative?

  - by Oden

  I found this linux distribution, called SmoothWall. I read its documentation and it looks pretty for me. The only problem is, that I'm not a big linux professional and I have also not a lot of experience but I want to know your thoughts about this "Firewall OS"! Can it be used for small-business environment, with 15-17 PC-s? I would use the server also as cache proxy. Is this a good idea? (I mean, using one server for two things)
