  • Rsync fails for files that start with underscore when destination is zfs

    - by Eric
    everyone. I'm using rsync3.1.0pre1 on Mac OS X 10.8.5, and am trying to rsync one folder to another. The destination is a ZFS volume mounted via SMB. The problem I'm having is that files that start with underscore (e.g., '_filename.jpg') are not being successfully synced to the destination. I get the following error message: rsync: mkstemp "/path/to/destination/._filename.jpg.NUgYJw" failed: Permission denied (13) In this case, '_filename.jpg' does not make it to the destination. I understand that rsync creates hidden, temporary files at the destination which are preceded with '.' and have a random file extension appended on the end. But the original filename starts with '', not '.', and I haven't asked rsync to copy extended attributes / resource forks over (unless it always does it). The rsync command I'm using is: rsync -avE --exclude='.DS_Store' --exclude '.Trash' --exclude 'Thumbs.db' --exclude '._*' --delete /source/ /destination/ Has anyone found a way around this problem? Thank you!

  • Copy file to WebDAV via Command Line on Windows 2003

    - by Boden
    I need to copy a file from a Windows 2003 server to a WebDAV folder (on the same server, if it matters). This operation will be performed via a batch script executed via Scheduled Tasks. I've enabled the WebClient service on the server. So far I've determined that I can do it like this: net use x: http://host/path copy c:\path\myfile.txt x: net use x: /delete 1) Is there a simpler way than creating a temporary mapped drive? Will it work via a batch file when no user is logged in? 2) Is there anything I should know about enabling the WebClient service on my server? Previously it was disabled, which I assume is default.

  • Open original Microsoft Office document (not "version 1") on Mac OS X Lion restart

    - by FlyingMolga
    My MacBook Pro running Lion has been frequently freezing lately, and I've had to restart with the power button. When Lion starts up again, the Microsoft Office applications that were running start and load different autosaved versions of the documents I had open (i.e. it does not open abc.xlsx but [version 1] of abc.xlsx). Sometimes it also opens the original files. Several times I've inputted data into these "version 1" files, only to try to save it and realize that it isn't the original file and is sometimes missing data that is contained in the original file. Is there any way to make autorecover open the actual document with the unsaved changes, instead of making a new temporary version?

  • How are suspected DoS attacks handled by webservers?

    - by Jan Kuboschek
    I rent a server somewhere out in Canada or so that I'm using to host a website of mine. That website has close to 400,000 pages that I wanted to index today. For that, I wrote a crawler a while back (see JCrawler on Stackoverflow.com). Now, I'm greedy and didn't want it to take too long so I ran multiple threads resulting in some 60+ requests per second from my IP. A couple minutes later, my server locked me out. I can still FTP into it, but I can't HTTP it. As server administrator or user, do you have any idea how servers usually handle these situations? Is it common to place a permanent or temporary ban on the IP or what is typically done? Naturally, I'll re-run my software with fewer requests once I'm back on.

  • How to optimize a postgreSQL server for a "write once, read many"-type infrastructure ?

    - by mhu
    Greetings, I am working on a piece of software that logs entries (and related tagging) in a PostgreSQL database for storage and retrieval. We never update any data once it has been inserted; we might remove it when the entry gets too old, but this is done at most once a day. Stored entries can be retrieved by users. The insertion of new entries can happen rather fast and regularly, thus the database will commonly hold several millions elements. The tables used are pretty simple : one table for ids, raw content and insertion date; and one table storing tags and their values associated to an id. User search mostly concern tags values, so SELECTs usually consist of JOIN queries on ids on the two tables. To sum it up : 2 tables Lots of INSERT no UPDATE some DELETE, once a day at most some user-generated SELECT with JOIN huge data set What would an optimal server configuration (software and hardware, I assume for example that RAID10 could help) be for my PostgreSQL server, given these requirements ? By optimal, I mean one that allows SELECT queries taking a reasonably little amount of time. I can provide more information about the current setup (like tables, indexes ...) if needed.

  • Wyse Simple Imager. Unable to Create Product Directory

    - by Steve
    I am trying to submit a post on www.technicalhelp.de, but I receive an error: Invalid Session. Please resubmit the form. This happens if I delete temporary internet files and log out and back in, and if I use a different browser, and if I use a proxy browser. Perhaps someone on this forum can help I am trying to push a Wyse device image to a USB thumb drive. The image is on a remote server, and the thumb drive is connected to my desktop PC. I am using Wyse Simple Imager to do this. When I select the following: Product: V90 Image Version: 5.010627.512 Image File: \servername\folder\OLD_Rapport\V90-withusb\9V90.i2d Almost instantly, without attempting any action, I receive the message: WyseImager Unable to Create Product Directory. Add Image Failed I have completely formatted the USB drive with FAT32. It is new out of the fox, and I can create folders in it. How do I fix this?

  • Use cell formatting (e.g. "Good", "Bad", "Neutral") in formulas?

    - by ngm
    I am compiling a comparison of different pieces of software in an Excel spreadsheet. It is a big long list of features (the rows), with each column being one of the applications I'm evaluating. I've used styles to visually show how well each product meets each feature, as well as the importance of that feature, and now I'm wondering if there's a way I can use those annotations in a formula. The table is like: . | Product A | Product B | Product C Feature A | blah blah blah Feature B | blah blah blah Feature C | blah blah blah .... | .... | etc | Where I've put 'blah' in the table above, in my actual spreadsheet is (potentially lengthy) descriptive text explaining something about this feature in the given product. I've then used the styles "Good", "Neutral" and "Bad" to visually annotate the description, to show how well each product meets that feature. For each feature I've also used the styles Accent4, 60% Accent4, 40% Accent4, etc, to annotate the importance of each feature. Now I'm wondering if somehow I can use those styles (the annotations) to tot up a total score for each product. e.g., Score for feature A = valueof(60% Accent4) * valueof(Good) Is it possible at all?

  • SQL queries break our game! (Back-end server is at capacity)

    - by TimH
    We have a Facebook game that stores all persistent data in a MySQL database that is running on a large Amazon RDS instance. One of our tables is 2GB in size. If I run any queries on that table that take more than a couple of seconds, any SQL actions performed by our game will fail with the error: HTTP/1.1 503 Service Unavailable: Back-end server is at capacity This obviously brings down our game! I've monitored CPU usage on the RDS instance during these periods, and though it does spike, it doesn't go much over 50%. Previously we were on a smaller instance size and it did hit 100%, so I'd hoped just throwing more CPU capacity at the problem would solve it. I now think it's an issue with the number of open connections. However, I've only been working with SQL for 8 months or so, so I'm no expert on MySQL configuration. Is there perhaps some configuration setting I can change to prevent these queries from overloading the server, or should I just not be running them whilst our game is up? I'm using MySQL Workbench to run the queries. Here's an example.... SELECT * FROM BlueBoxEngineDB.Transfer WHERE Amount = 1000 AND FromUserId = 4 AND Status='Complete'; As you can see, it's not overly complex. There are only 5 columns in the table. Any help would be very much appreciated - Thanks!

  • Nagios and rrd on a old server

    - by Pier
    I have an old server (P4 based) on which nagios (and all the other tools to monitor) is running. In the last few weeks we are seeing a strange behavior. In the /var/spool/pnp4nagios (where temporary files are stored before getting processed by pnp4nagios daemon) we have many files like perfdata.1274949941-PID-18839 and we get an error in npcd.log: [05-27-2010 11:17:46] NPCD: ThreadCounter 0/15 File is perfdata.1274951306-PID-27849 [05-27-2010 11:17:46] NPCD: File 'perfdata.1274951306-PID-27849' is an already in process PNP file. Leaving it untouched. Sometimes some graph are not drawn. The server is pretty loaded (around 5-6 normally) and i suspect that npcd goes in timeout and leave those files behind. What could I do (apart from change the server)? Few infos about the system: centos 5.5 nagios 3.2.1 pnp4nagios 0.6 (from sources) Thanks

  • IIS7 is gzipping files but not serving the gzipped version.

    - by ptrin
    By following a number of helpful blog posts I have configured IIS to gzip my static files. I have even enabled Failed Request Tracing and filtered to the 200 status code, and I can see the successful compression events taking place as well as the finished headers, which look like this: Headers="Content-Type: text/css Content-Encoding: gzip Last-Modified: Mon, 04 Oct 2010 17:35:08 GMT Accept-Ranges: bytes ETag: "02ef37cea63cb1:0" Vary: Accept-Encoding Server: Microsoft-IIS/7.5 X-Powered-By: ASP.NET " However, when I test in Fiddler and Firefox the Content-Encoding header is missing, and the file is not gzipped. This is a similar issue to this question which was never resolved. IIS is generating the gzipped files which I can see in C:\inetpub\temp\IIS Temporary Compressed Files . Does anyone know how I can troubleshoot this?

  • Which SQL Server edition?

    - by StaringSkyward
    We need a new install of windows server and sql server to replicate a couple of databases to a geographically separate location from an existing application (over a site-to-site VPN). The source database is SQL Server 2005. However, this is a temporary solution since the client is aiming to implement a different system entirely, so we are looking to find the minimum specification of both windows server and sql server to do this. We are finding the SQL server features per edition and licensing a little difficult to understand, hence the question. Am I correct in thinking that we can replicate data using transactional replication from SQL Server 2005 to 2008 web edition and we can install sql server web edition on windows 2008 web edition also? Thanks.

  • Scanning to network share

    - by tking
    In our environment we have several printers with the scan to folder functionality set up. It worked pretty well. Long story short- I needed to reboot our file server one evening (the server whose $hares where all the scans go), upon on boot up I received a message stating the name of the file server (i.e AcmeFS1; Windows Server 2003) could not be used because there was a duplicate name on the network. I found that somehow another printer on the network was using the name of the file server. Weird - I know. People could no longer scan to their folders. I ran an nbtstat on the file server and found that the local netbios name table was empty. I renamed the offending printer and rebooted the file server once more. This time, no error, and once I ran nbtstat again, I found that correct name and domain in the local netbios name table. Problem is, scan to folder is still not working. I know this was working before I rebooted the file server the first time. Anyone have any idea what is going on and how to fix? Thanks. FIXED: Not sure why the reboot didnt fix it but I restarted the "Server" service on the file server and the problem went away.

  • Windows Media Player functionality for Ubuntu

    - by Xeoncross
    I have way to many music files to bother with setting up playlists. Especially since my files locations keeps changing as I move stuff around and swap between different computers, different mount points, and even different Operating Systems! So managing my media with any application is doomed to failure. However, since I still want to listen to the music I usually just select all the files I want to play at a time and then right-click to open them in a media player. Works great in windows media player and places all the tracks in a temp playlist on the sidebar. Fails in ubuntu using Rhythmbox since it doesn't understand "temp" playlists and just keeps adding files to your FULL listing of all sings on your whole computer. I have over three copies of some tracks now in my audio collection - and all of them are now invalid because the location of the files has changed. So what media player (for Ubuntu) works well with just temporary playlists and will allow me to open up my files without adding them to a collection?

  • Alternatives to y4mstabilizer; deshaking video

    - by Vi
    "Deshaking" means fixing the video captured from camera hold in hands. Is there open source video deshaker apart from y4mstabilizer from mjpegtools? Patch for mencoder is preferred. My current command line for processing video looks like: mplayer video_from_camera.avi -nosound -vo yuv4mpeg:file=/dev/stdout -really-quiet | y4mstabilizer -n -a 0.8 -r 30 -s 100 | mplayer -cache 1000 /dev/stdin -noconsolecontrols -vf crop=500:380:70:50,denoise3d=3:3:5:5 -vo yuv4mpeg:file=temporary.yuv y4mstabilizer is itself very unstable and often crashes (and it didn't work at all until I have patched memory allocation in it).

  • VPN: Disable class based route addition for Windows XP/Vista

    - by brgsousa
    Paraphrasing this SuperUser link: When you set up a VPN, the Windows default is to enable "Use default gateway on remote network." A new default route is added to the routing table pointing to the remote network's gateway, and the existing default route has its metric increased to force all Internet traffic to traverse the tunnel and use the remote network's gateway. All traffic uses the VPN, and traffic destined for the outside world is directed to the remote gateway. When the VPN drops, the route to the remote gateway is removed and the original default route is set back to the original metric. Unchecking "use default gateway on remote network" means that new default route isn't added, so Internet traffic goes out the local gateway, but a new classful route is added to the routing table, using the local adapter's IP, pointing down the VPN. Only traffic destined for the classful network of the local adapter goes down the VPN. This may not be what you want. Checking "Disable class based route addition" means that classful route isn't added to your machine when the VPN starts up, and you'll need to add the appropriate routes for networks that should be routed through the tunnel. But, the option "Disable class based route addition" is available ONLY for Windows 7. How can I do something like that for Windows XP or Vista since they don't have that option? I have searched about for that but, no solution yet.

  • Help recovering lost text from a refreshed Chrome webpage (it was in the clipboard as well)? [closed]

    - by tobeannounced
    Possible Duplicate: Chrome: where is the location to save browse temporary files Ok, so here's what happened - and yes, it was pretty stupid by me: I wrote up and submitted a post on Stack Overflow It was not suited to be placed on Stack Overflow as someone pointed out to me, so I deleted the post (this was a few hours ago) I copied the text into a new question page on Super User, but didn't submit it yet I accidentally just refreshed the webpage that had the text, and the question has now been deleted from Stack Overflow I have Lazarus installed, however the Chrome version doesn't have many features and the text was not recoverable from there. I do not have a clipboard manager, but the text was copied to my clipboard - so is there any way to get this back (Windows 7)? Although the post on Stack Overflow was deleted, I suppose it would have existed in my cache - could I recover it from there? Would the post on Stack Overflow exist in an rss feed anywhere? Many thanks, and I hope I can find this - and I am sure that the solution will prove valuable for me (and others) in the not too distant future once again.

  • Tool or website or process to display previews of website templates residing in archive files?

    - by Tony_Henrich
    I have hundreds of website templates in rar or zip files. To view any of them I have to extract the archive to a temporary folder and then view the template in there. It's a time consuming manual process to do this for each template Is there a tool which enables me to quickly preview the templates in the files? OR (if I extract each template into a separate folder off a master folder) A web app which can enable previewing of each template by automatically creating a link or a preview image (similar to template sites) of the home page for? OR any method to preview the templates in the fastest convenient way possible?

  • Problem with the hosts file under windows 7

    - by martani_net
    I updated some entries in the hosts file "C:\WINDOWS\System32\drivers\etc" to make google for example point to 127.0.0.1 # Additionally, comments (such as these) may be inserted on individual # lines or following the machine name denoted by a '#' symbol. # # For example: # # 102.54.94.97 rhino.acme.com # source server # 38.25.63.10 x.acme.com # x client host 127.0.0.1 localhost ::1 localhost 127.0.0.1 google.com This works fine under windows Vista, but not under Widows 7. When I type google, it goes directly to Google's website. For info, I am not using a proxy server. I think there are some temporary DNS settings that must be flushed, but I don't know how, anyone knows how to fix this? Thank you.

  • Corsair SSD appears completely blank and does not retain written data

    - by ebanders
    I have a 180GB Corsair SSD (model# CSSD-F180GB2-BRKT) as the primary drive in a Windows laptop. Recently the machine became unbootable after installing Windows updates. Windows installed updates before the machine shut down and the next time the machine boot up it complained about not being able to find a bootable device. After finding fixmbr unsuccessful at making the machine unbootable, I investigated a little within knoppix. Fdisk revealed an empty partition table. A scan by Testdisk came up empty. And finally 'head -c 1024 | hd' reveals all zeros. Creating a primary partition spanning the whole disk completes successfully, but after a reboot the disk appears empty again. dmesg reveals no read or write errors. smartctl indicates that the drive is healthy- although the SMART attribute values do not appear to be read properly. "Data Page | WARNING: PREVIOUS ATTRIBUTE HAS TWO" and "Threshold Page | INCONSISTENT IDENTITIES IN THE DATA" messages appear within the table of values. I don't have much experience with SSDs. Is this drive dead or something? Can anyone recommend any diagnostic tools that may be suited for diagnosing SSDs?

  • Formatting not retained in paste from Ditto (clipboard manager). Plain text pasted instead [Solved] Add supported types

    - by Jeff Kang
    I'm trying to use Ditto on the Ditto documentation. If I were to copy the table of contents, then paste it (without Ditto) to the word processor, I get http://i.imgur.com/V1GU3.png, and the formatting is maintained. As as a result of the copy operation, the table of contents also goes into the Saved Items List (= History List = Lists the Clips saved from the Clipboard) in Ditto’s Main Window: I open a blank document to paste from Ditto instead of the default clipboard, and press either Ctrl-`, the default Ditto window activation Global Hot Key, or click the tray icon. From this point, I can do 3 things to close the Ditto window, and place the item on the clipboard (the default clipboard?). Select the item, and press Enter Put the cursor on the item, and double-click Select the item, and press Ctrl-c 1) and 2) send a right-click where the cursor is, after the Ditto window closes (presumably to have the paste option ready to access?): Ctrl-c just closes the Ditto window. Whichever method is used, the contents are pasted in what I believe is plain text: http://i.imgur.com/mQAZH.png How do I keep the formatting that the default clipboard keeps? Thanks.

  • Sharing RAM resources between 2 or more computers

    - by davee44
    I know there was a somewhat similar question before: How to share CPU or RAM? But, let me just specify it a little more... When Microsoft Windows requires more RAM capacity than available it uses a swap-file to temporarily store the data there, this is actually something like a hard-drive-based RAM. This technology is used for many years. Theoretically, it shouldn't be too hard to implement a similar technology that uses the RAM of different computer(s) in the network for temporary data storage. This just requires a software that runs on computers in the network that accepts and returns data from/to the main computer and keep that data in the RAM; plus the operation system of the main computer must have the ability to use computers in the network instead of (or in addition to) the swap-file. I wonder, are there any implementations of this idea? This would allow users to build RAM clusters using all of their home or office computers, that will boost the performance of a single computer for some development/gaming/video tasks, etc.

  • Kindle (client) for Mac--text search or highlighting/notes?

    - by doug
    just so we're clear, i'm talking about the client/software version here--ie, that you install on your Mac or PC--not the device. The Kindle client was recently released for the Mac. I downloaded it and bought a couple of Kindle-edition books to view on this client. Astonishingly, two features i consider to be more or less essential to any ebook reader are missing in the Kindle client, either that, or i can't find them: (i) text searching; and (ii) highlighting text. First, does anyone know how to access the search feature? I'm aware of the "Go To" button at the top middle of the reader window--the options in that menu when you click the button are: "Cover", "Table of Contents", "Beginning" and "Location." "Location" requires that you type in an integer (but it doesn't correspond to page number--e.g., typing "167" brought me to the table of contents), not a search term. Second, there's a button on the upper right-hand corner of the window "Show Notes and Marks" yet i can't find any way to highlight text. The only kind of "note" or "mark" i have been able to record is to "bookmark" a page by clicking the "bookmark" button also at the top of the window.

  • (Possibly) Corrupted DDCrypt self-decrypting file

    - by sca
    I recently discovered some files I had encrypted and archived on a CD using DDCrypt 2.0, which is a small encryption utility from back in the day. One of its functions is to create self-decrypting files, which are essentially EXE files that you can enter a password and then have the file extracted onto your filesystem. Unfortunately, I can't seem to get them to do this properly. They appear to be decrypting and then at the last moment I get the error: Error opening encrypted file C:\users\username\Temp\dde3cfa.tmp Reason: Success and then another dialog immediately says Error extracting ddc file. I'm not really sure what this means (certainly not success), but I've checked out the temporary file and it appears to be garbage data (although of the right file size). I don't know if anyone has an idea what might be done here to extract the files, or has dealt with a similar situation before. Any ideas are appreciated! Thank you in advance for your time and any help you can provide.
