  • Backing up data from server to laptop ?

    - by Patrick
    I need a tool to automatically backup my Drupal installations from my server to my laptop. In other terms, I need to copy 1 folder (all my Drupals are inside this folder) and all databases. So I was wondering if I just need to write a script on my laptop connecting to the server every week copying the folder with all mysql databases informing me by email if the backup has been succesfull do you know if I can find some tutorial for it ? or download such script ? thanks

  • What hash should be used to ensure file integrity?

    - by Corey Ogburn
    It's no secret that large files offered up for download often are coupled with their MD5 or SHA-1 hash so that after you download you can verify the file's integrity. Are these still the best algorithms to use for this? Obviously these are very popular hashes that potential downloaders would have easy access to. Ignoring that factor, what hashes have the best properties for being used for this? For example, bcrypt would be horrible for this. It's designed to be slow. That would suck to use on your 7.4 GB dual layer OS ISO you just downloaded when a 12 letter password might take up to a second with the right parameters.

  • Statically Display Excel drop-down boxes

    - by Chris Gunner
    I'm looking to present an Excel questionnaire I have written to the board, via either paper or presentation slides. It uses a lot of drop-down boxes, and so I'm looking for any ideas on how one might go about showing the options for each response (from the drop-down boxes), without having to manually print screen a bunch of times and pasting the results into Visio. Has anyone come across a nie easy, fast method of doing this?

  • HDD situation - what would be best - data and backup

    - by Sam Johnson
    I just installed W8 on an Intel 330 180 GB SSD. I have 3 1TB HDDs. 1 HDD will be external for backup. 2 HDDs are then available for my PC. I do not need 2 TB of storage, so I thought I'd set these up to be exact clones of one another, so that if one dies I have a backup in the computer to go along with my external. Is this a good set up? How best would this be accomplished? I've heard people suggest RAID but I've never done RAID, have no idea what it is, and have no idea how to set it up in my BIOS. Thanks in advance

  • How Does EoR Design Work with Multi-tiered Data Center Topology

    - by S.C.
    I just did a ton of reading about the different multi-tier network topology options as outlined by Cisco, and now that I'm looking at the physical options (End of Row (EoR) vs Top of Rack(ToR)), I find myself confused about how these fit into the logical constructs. With ToR it also maps 1:1: at the top of each rack there is a switch(es) that essentially act as the access layer. They connect via fiber to other switches, maybe chassis-based, that act as the aggregation layer, that then connect to the core layer. With EoR it seems that the servers are connecting directly to the aggregation layer, skipping the access layer all together, by plugging directly into what are typically chassis switches. In EoR then is the standard 3-tier model now a 2-tier model: the servers go to the chassis switch which goes straight to the core switch? The reason it matters to me is that my understanding was that the 3-tier model was more desirable due to less complexity. The agg switch pair acts as default gateway and does routing; if you use up all of your ports in your agg layer pair it's much more complicated to add additional switches, than simply adding more switches at the access layer. Are there other downsides to this layout? Does this 3-tier architecture still apply in some way in EoR? Thanks.

  • Data capture from other sheet into Summary sheet

    - by Hemant
    an Excel workbook which has Summary sheet, Pending and Master Sheet. My requirement is below and try to develop a Macro or VB logic for excel • I want to control this workbook from Summary sheet. o Generate Fault Summary – ? I have set logic but if doesn’t give warning if sheet name is exists , so need to add this logic . ? When we press the Fault Report Summary command button then it copy the master sheet with cell “A6” Name and will hide the Master sheet. Again when you select the another Month name then it will generate the sheet for that month name. o Generate Toll System Uptime ? When I select the sheet name and “Week” then Press the “Enter “Command button then it should get the result from that sheet number . Each sheet number has Month detail in B2 Cell. ? To calculate the Uptime formula for Week wise is • Week-01 = (1680-SUMIFS(L5:L23,B5:B23,"="&B2,B5:B23,"<="&(B2+6)))/1680 • Week-02 =(1680-SUMIFS(L5:L23,B5:B23,"="&(B2+7),B5:B23,"<="&(B2+13)))/1680 • Week-03 =(1680-SUMIFS(L5:L23,B5:B23,"="&(B2+14),B5:B23,"<="&(B2+20)))/1680 • Week-04 =(1680-SUMIFS(L5:L23,B5:B23,"="&(B2+21),B5:B23,"<="&(B2+27)))/1680 • Month =(1680-SUMIFS(L5:L23,B5:B23,"="&(B2),B5:B23,"<="&(DATE(YEAR(B2),1+MONTH(B2),1)-1)))/1680 ? Result should reflect in Summary sheet at B18 cell . o Pending Fault Report Summary ? When segregate the report on its status like which one is open or Close . It is open then it is Pending Fault Report and when it is Close status it means it is closed. ? If any fault which has OPEN status in all sheets(Jan-13,Feb-13,Mar-13….etc) then it should be come as well as in Pending Sheet which ascending date order. ? When it’s status is changed then it should be moved in that month sheet or nearby fault created date. It status is close then it should not be available in pending sheet as it’s status is Closed. ? Each fault has Reported date and we monitor all fault according reported date. ? When we press the Update Fault Report Summary command button then it should update as above logic. ? Some time we export the Pending fault report , so date calendar should be present in Start and End date to Choose the date. When we press the Export command line then it should export the Pending fault report and able to save in Excel,PDF.

  • Is an NTBackup of a MySQL data directory reliable

    - by Justin Dearing
    This question was asked on the MySQL forums in 2004 with no answers. I'm installing MySQL 5.0.x on a Windows 2003 Server for use with Drupal. I began to configure the backup with mysqldump when it occurred to me that an ntbackup taken using shadow copying should be reliable enough for backing up the database. Is there any flaw in my logic?

  • Indexing Service filter daemon keeps crashing on Windows XP; something worse underneath?

    - by IVR Avenger
    The Indexing Service filter daemon keeps crashing on my Windows XP Pro machine, with the following error message: Indexing Service filter daemon has encountered a problem and needs to close. We are sorry for the inconvenience. Not a big deal, I can click "Don't Send Error Report" all day. But what's going on, here? Is this a service that I need? Is the frequent crashing indicative of something worse that's happening behind the scenes?

  • Finding optimal ddrescue command line options where Accuracy > Speed

    - by gav
    I'm read up a bit about this tool and obviously looked at the man pages. The trouble is that ddrescue takes so long I need to get the command right first time. I wasn't sure how to improve on the vanilla; $ sudo ./ddrescue -v /dev/disk0s5 MyVolImage.dmg MyVolRescue.log $ sudo ./ddrescue -v MyVolImage.dmg /dev/disk1s3 MyVolRestore.log From HSF+ to HSF+ drives Source (Broken) HDD is connected via USB 2.0 Dest HDD is inside MacBook I would choose accuracy over speed There seem to be a lot of options but I'm not sure how they impact quality and speed of recovery. Thanks, Gav

  • How to start a service at boot time in ubuntu 12.04, run as a different user?

    - by Alex
    I have a server ClueReleaseManager which I have installed on a Ubuntu 12.04 system from a separate user (named pypi), and I want to be able to start this server at startup. I already have tried to create a simple bash script with some commands (login as user pypi, use a virtual python environment, start the server), but this does not work properly. Either the terminal crashes or when I try to ask the status of the service it is started and I am logged in as user pypi ...? So, here the question: What are the steps to take to make sure the ClueReleaseManager service properly starts up on boot time, and which I can control (start/stop/..) during runtime, while the service is running from a user pypi? Additional information and constraints: I want to do this as simple as possible Without any other packages/programs to be installed I am not familiar with the Ubuntu 12.04 init structure All the information I found on the web is very sparse, confusing, incorrect or does not apply to my case of running a service as a different user from root.

  • Finding a private (NAT) host's IP using historic destination data

    - by l0c0b0x
    The issue: An unknown private (NAT) client is infected with malware and it's trying to access a Bot server at random times/dates. How we know about this: We receive bot traffic notices/alerts from REN-ISAC. Unfortunately, we don't receive those until the next day after it has happened. What they provide to us is: The source address (of the firewall) The destination addresses (it varies, but they're going to network subnet allocated to a German ISP) The source port (which varies--dynamic ports). Question: What would be the best approach to finding this internal host (historically) with a Cisco ASA as firewall? I'm guessing blocking anything to the destination address(es), and logging that type of traffic/access might allow me to find the source host, but I'm not sure which tool/command would be the most useful. I've seen Netflow thrown into a few responses when it comes to logging, but I'm confused with it's association of Logging, NAL, and nBAR, and how they relate to Netflow.

  • How to compare data in 2 columns in Excel and then in one cell, determine if there are similar data in both columns

    - by Charmaine Camara
    I have 2 columns in Excel: the first contains a list of employee names who perform function A, and the second contains a list of employee names who perform function B. What I want is to identify, in one cell, if there is one employee whose name appears in both the first and second columns. It does not have to show which name(s) appears in both columns, it just needs to identify IF there are any names that appear in both columns.

  • MySQL Server - Got error -1 from storage engine

    - by Bobby
    I am currently trying to restore a MySQL table from the .ibd file. I have been following the instructions on the MySQL reference manual on how to use DISCARD and IMPORT TABLESPACE to replace the .idb files. Discarding the tablespace returns no error and the file is deleted however IMPORTING the replacement .ibd file yields a "Got error -1 from storage engine" error. There doesn't seem to be too much information about what exactly an error -1 is. Does anybody have any further insight as to why an import table space isn't working?

  • Almost All Xenserver Logical Volumes Disappeared - Recovery?

    - by Alex
    We had a hard disc crash of one of two hard discs in a software raid with a LVM on top. The server is running Citrix xenserver. On the hard disk which is still intact, the volume group gets detected well, but only one LV is left. (some hashes replaced by "x") # lvdisplay --- Logical volume --- LV Name /dev/VG_XenStorage-x-x-x-x-408b91acdcae/MGT VG Name VG_XenStorage-x-x-x-x-408b91acdcae LV UUID x-x-x-x-x-x-vQmZ6C LV Write Access read/write LV Status available # open 0 LV Size 4.00 MiB Current LE 1 Segments 1 Allocation inherit Read ahead sectors auto - currently set to 256 Block device 253:0 root@rescue ~ # vgdisplay --- Volume group --- VG Name VG_XenStorage-x-x-x-x-408b91acdcae System ID Format lvm2 Metadata Areas 1 Metadata Sequence No 4 VG Access read/write VG Status resizable MAX LV 0 Cur LV 1 Open LV 0 Max PV 0 Cur PV 1 Act PV 1 VG Size 698.62 GiB PE Size 4.00 MiB Total PE 178848 Alloc PE / Size 1 / 4.00 MiB Free PE / Size 178847 / 698.62 GiB VG UUID x-x-x-x-x-x-53w0kL I could understand if a full physical volume is lost - but why only the logical volumes?

  • Excel chart: How to reverse the X axis of time series data

    - by JohnnyLambada
    In Excel 2003, I have a time series from a financial report that goes something like this: 2007 2006 2005 Amount 300 200 100 I want to create a graph of the time series that looks something like this (please excuse the ugly ascii graph): 300| .x | ... 200| .x.. | ... 100| x |____________________ 0 2005 2006 2007 But intead of getting an upward sloping graph, excel wants to put my time series in reverse (the way it actually appears in the spreadsheet). Is there any way to make excel display the x axis in reverse of the way it normally does? I've tried manually reversing the range in the chart dialog (changing a range of B1:D3 to D3:B1), but excel just puts it back.

  • How to get data from a borked Windows Home Server

    - by harhoo
    Yesterday we had a power surge, followed by a power outage. This left my WHS borked: powering on just gives to a flashing blue light (the led on the power supply also flashes green) - no fan or boot activity, nothing. I urgently needed some files off there in the short term (and the 500GB of photos, music, personal video etc in the long term) so I took the hard drive out and put it in my computer. The files and folders showed up, but I couldn't access them - clicking on an image gave an invalid image error in Picasa, I couldn't play MP3s etc. I changed the ownership and permissions of the files, still nothing. I booted in with a LiveCD, the same: files appear, but won't open. Is there anything else I can do? I'm now wondering if it was just the power cable that's broken, but if so, why can;t I access my files from the hard drive? If it is the power cable, and I replace that and the hard drive, will I have done any harm messing around with ownership and file permissions?
