  • Mount --bind persistence over reboot

    - by vnuk
    I'm having trouble finding an answer for this question Does mount --bind persist over reboot? On my CentOS it looks like it doesn't, so I've placed apropriate mount --bind calls in rc.local. How can I do mount --bind to avoid rc.local scenario?

  • Wifi channel interference

    - by artfulrobot
    In my neighbourhood there are: 11 wifi signals on channel 1 2 wifi signals on channel 4 (including mine at the mo) 8 on channel 6 6 on channel 11 According to the diagram on wikipedia Mine on channel 4 will suffer interference from channel 1 and channel 6, so a total of 20 other networks(!). So would I be better to join channel 11, even though my network is then in direct competition with the 6 others? I suppose the question is: what's worse: direct interference (meaning that on the same channel) from 6 or fringe interference from many more networks?

  • ntbackup with two backup plans?

    - by feklee
    Is it possible to use ntbackup.exe (Windows XP SP3, 32) with two incremental backup plans? An example: "My Documents": every day, incrementally to D:\My_Documents.bkf Drive C: every month, incrementally to D:\All.bkf As far as I understand it, ntbackup.exe marks files as having been backed up in the file system. Thus, two incremental backup plans would interfere in a bad way. So, I assume that the answer to my question is: No But maybe I'm wrong...

  • Does Windows 8 support UTC as BIOS time?

    - by Roren
    Is there any way to use Windows 8 with time in UTC in BIOS? I know there is a way to do it in Windows 7 (in this question: Does Windows 7 support UTC as BIOS time?), but this solution makes my system unbootable. Windows expects the bios clock to be set to local time by default. In Windows 7 and before, there was a registry hack to change this behavior so that it could expect UTC – is there an equivalent in Windows 8?

  • Host's sys admins - can they view files?

    - by FullTrust
    Hi, Just a quick question. When using shared hosting, can system admins (employed by the host) access your files and read your database connectionstring details? Can they also access your database, and view the files, without a connectionstring? I'm assuming there's a certain level of trust, but is this possible/common? Thanks

  • How to make Linux to re-detect network interfaces?

    - by ablmf
    For some reason, ifcfg-eth* under /etc/sysconfig/network-script were deleted. Is there any tools that could detect network interfaces and re-generate these files? Another question : If I manually added ifcfg-eth0, is there any method to make it work without reboot? I tried "/etc/init.d/networking restart", and it doesn't work.

  • Can Remote Desktop Services be deployed and administered by PowerShell alone, without a Domain in WIndows Server 2012 and 2012 R2?

    - by Warren P
    Windows Server 2008 R2 allowed deployment of Terminal Server (Remote Desktop Services) without a domain, and without any insistence on domains. This was very useful, especially for standalone virtual or cloud deployments of a server that is managed remotely for a remote client who has no need or desire for any ActiveDirectory or Domain features. This has become steadily more and more difficult as Microsoft restricts its technologies further and further in each Windows release. With Windows Server 2012, configuring licensing for Remote Desktop Services, is more difficult when not on a domain, but possible still. With Windows Server 2012 R2 (at least in the preview) the barriers are now severe: The Add/Remove Roles and Features wizard in Windows Server 2012 R2 has a special RDS deployment mode that has a rule that says if you aren't on a domain you can't deploy. It tells you to create or join a domain first. This of course comes in direct conflict with the fact that an Active Directory domain controller should not be the same machine as a terminal server machine. So Microsoft's technology is not such much a Cloud Operating System as a Cluster of Unwanted Nodes, needed to support the one machine I actually WANT to deploy. This is gross, and so I am trying to find a workaround. However if you skip that wizard and just go check the checkboxes in the main Roles/Features wizard, you can deploy the features, but the UI is not there to configure them, and when you go back to the RDS configuration page on the roles wizard, you get a message saying you can not administer your Remote Desktop Services system when you are logged in as a Local-Computer Administrator, because although you have all admin priveleges you could have (in your workgroup based system), the RDS configuration UI will not accept those credentials and let you continue. My question in brief is, can I still somehow, obtain the following end result: I need to allow 10-20 users per system to have an RDS (TS) session. I do not need any of the fancy pants RDS options, unless Microsoft somehow depends on those features being present. I believe I need the "RDS Session Host" as this is the guts of "Terminal Server". Microsoft says it is "full Windows desktop for Remote Desktop Services client. I need to configure licensing so that the Grace Period does not expire leaving my RDS non functional, so this probably means I need a way to configure TS CALs. If all of the above could technically be done with the judicious use of the PowerShell, I am prepared to even consider developing all the PowerShell scripts I would need to do the above. I'm not asking someone to write that for me. What I'm asking is, does anyone know if there is a technical impediment to what I want to do above, other than the deliberate crippling of the 2012 R2 UI for Workgroup users? Would the underlying technologies all still work if I manipulate and control them from a PowerShell script? Obviously a 1 word Yes or No answer isn't that useful to anyone, so the question is really, yes or no, and why? In the case the answer is Yes, then how.

  • Is it okay to use a SSH key with an empty passphrase?

    - by mozillalives
    When I first learned how to make ssh keys, the tutorials I read all stated that a good passphrase should be chosen. But recently, when setting up a daemon process that needs to ssh to another machine, I discovered that the only way (it seems) to have a key that I don't need to auth at every boot is to create a key with an empty passphrase. So my question is, what are the concerns with using a key with no passphrase?

  • Video Chat going through a server

    - by Alexander
    I'm trying to build a simple video chat client on the mac as a little project and I want it to be able to go over my own little server and arrive at the other end (so going over the internet rather just locally). So my question is if there are any references I should look for online on how to handle something like this on the server side and such. Any links or pointers would be a great help, thanks!

  • Having a netbook with closed lid will decrease the lifespan of it?

    - by LanceBaynes
    I need a cheap netbook for "router" functions. [OpenBSD/Scientific Linux/whatever will be on it on OS level]. So once I configure it I will put it somewhere down for YEARS. The Question is: What is the lifespan difference of the netbook if it will be [for years]: with opened lid with closed lid I don't think there will be heat problems, because netbooks doesn't produce too much heat. But will ex.: a closed lid [for years] decrease the lifespan of a netbook?

  • Recovering data from failed Raid configuration with 4 drives and two raid sets (Asus P6T / Intel ICH10r)

    - by user56365
    I've added the complete detailed version for my question below for those who can help, but want to quickly summarize my question first. I setup two Raid arrays using (4) WD Raptors, a striped set for the OS and 1+0 set for crucial data. After booting once out of the 50 times a cable fell out, the drive wasn't recognized in the array anymore. After trying to fix it, another drive did the same. I now have two drives remaining, luckily with the parity information. I know the striped set is gone, but I need the data on the other set. Can anyone recommend anything to recover the data, or fix the two drives that doesn't allow the raid controller to recognize the drives, even though they are listed on the utility screen as still apart of the configuration but that they are not found? More Details I recently upgraded to a ASUS P6T motherboard with an Intel ICH10R raid controller and changed my previous 4 drive raid array from strictly a Raid 1+0 set to a Raid 0 for the OS/Page/Scratch drive and a Raid 1+0 set for crucial data. I never had problems after upgrading with my configuration, even when a drive died and was replaced. I managed to rebuild the array fine. Unfortunately this time around, a cable came unattached and I booted my system up until the raid status screen with the degraded error. This shouldn't have been a problem, but after I attached the drive it was no longer recognized as a member in the array. Both drives actually show up as a non-member disk. I've spent a very, very long time online trying to find information or support and haven't had much luck. After spending time trying to scan the drive for errors, damaged partition info, etc.. another drive in the set decided it didn't want to be recognized as a part of the array. At this point, I have two out of the four drives still functioning, but the Raid 1+0 array went from degraded to failed and I must find a way to retrieve that data. I think the two drives still in the array have the parity information because they show up as OS (110GB),BACKUP(80GB) and OS:1(110GB),BACKUP(80GB) under windows data management. The other two are simply 74gb Raw unallocated Is it possible recover the data using those two drive only, and which tool would I use? Could it be a simple partition table or any other error that is repairable with hard drive utilities out there? I know the Raid 0 set is done for, but I would assume because the correct drives failed in a 1+0 config to save the data I can retrieve it some how.

  • Is it possible to prevent the win7 sleep state while using spotify?

    - by Skadlig
    Does anyone know if there is a way to prevent windows 7 to go to sleep while using Spotify? I have read the answers in this question but if it's possible I'd rather not resort to start a third party program like insomnia every time I want to listen to music. So are there a setting or a registry entry buried somewhere deep in windows that allows you to do this? Either for a group like "all audio" or for specific programs?

  • Dual boot: Windows XP and Ubuntu

    - by user19455
    (I know that there are some questions similar to this one, but the ones I have read (and I have read more than one, did not answer my question) I have installed, in two physically different hard drives Windows XP and Ubuntu 9.0. I would like to have a dual boot that, if nothing was pressed, the Windows XP would start automatically. I have read about Grub but got the impression that it wasn't possible to default the operating system to start to something other than Ubuntu. Thanks.

  • How to get a "live screenshot" in windows

    - by alexei7
    Quick question – do you know any software or way of doing a live screenshot of a window and bring it to the foreground? It’d be like picture link in Excel... My problem is that I am running various tasks in IE and Oracle, and they take forever but i have no way of seeing if they’re done without tabbing back into them all the time. I want something so that I can always see in the foreground the status bar/egg-timers thingy for them. Thanks all

  • Understanding exim configuration files

    - by bobobobo
    So, I want to understand what's going on with this Exim configuration directory. In /etc/exim4, there's: * exim4.conf.template * update-exim4.conf.conf * conf.d The conf.d has a mess of directories and files, and inside each are a bunch of if statements which I find really different. For example: maildir_home: debug_print = "T: maildir_home for $local_part@$domain" driver = appendfile .ifdef MAILDIR_HOME_MAILDIR_LOCATION directory = MAILDIR_HOME_MAILDIR_LOCATION .else directory = $home/Maildir .endif .ifdef MAILDIR_HOME_CREATE_DIRECTORY create_directory .endif .ifdef MAILDIR_HOME_CREATE_FILE My question is, where do the CAPS VARIABLES get defined how can I change them why are there so many if statements in these configuration files?

  • How to re-enable Autoplay for removeable drives on Windows 7

    - by Clay Nichols
    When I plug a USB thumb drive into my Win7 PC, it no longer auto-launches the window giving me options like "Import Photos" or "browse". The drive is recognized but nothing autolaunches. Similarly, CD's don't autoplay either. I verified that Win7 is set to autoplay, per method 1 and 2 of: http://www.sevenforums.com/tutorials/27544-autoplay-enable-disable-autorun.html FYI, there is a similar question (but for Windows XP) here on SU.
