  • Trying to unpack 2.5GB .tar.gz file on Linux but getting "An error occurred while trying to open the archive"

    - by TMM
    Hi, Is there a limit on Linux for the file size of a .tar.gz (or its contents). I am currently creating a .tar.gz (both through the UI/"Compress As" and also through the command line) file for 2 files (6GB and 2GB), and even though it is created successfully, when I try to unpack it using Ark it throws the error "An error occurred while trying to open the archive". I have seen some places that it might be better to archive the file into several smaller .tar.gz files, but I was wondering exactly how to do this (and subsequently unpack the files). Also, is it totally impossible to use the 1 .tar.gz file approach as this would be much simpler. Thanks in advance, Tim

  • What could cause a file system to spontaneously unmount or become invalid for a short time?

    - by Ichorus
    We've got DB2 LUW running on a RHEL box. We had a crash of DB2 and IBM came back and said that a file that DB2 was trying to access (through open64()) unmounted or became invalid. We have done nothing but restart the database and things seem to be running fine. Also, the file in question looks perfectly normal now: $ cd /db/log/TEAMS/tmsinst/NODE0000/TEAMS/T0000000/ $ ls -l total 557604 -rw------- 1 tmsinst tmsinst 570425344 Jan 14 10:24 C0000000.CAT $ file C0000000.CAT C0000000.CAT: data $ lsattr C0000000.CAT ------------- C0000000.CAT $ ls -l total 557604 -rw------- 1 tmsinst tmsinst 570425344 Jan 14 10:24 C0000000.CAT With those facts in hand (please correct me if I am mis-interpreting the data at hand) what could cause a file system to 'spontaneously unmount or become invalid for a short time'? What should my next step be? This is on Dell hardware and we ran their diagnostic tools against the hardware and it came back clean.

  • I believe I need a wireless access point, but can I do it with a wifi router?

    - by Flotsam N. Jetsam
    My needs are simple, I think: I have a laptop upstairs with a usb wifi that I use to connect to my neighbor's wifi which I share (with their knowledge). I have a laser printer downstairs that my wife doesn't wants to stay down there (big, bulky and ugly), but that we both need to print stuff off. It has wired networking and I have wired hub and router down there. The usb wifi on the laptop has absolutley the best reception I've ever seen or heard of. I cannot get onto the neighbor's net with the thing downstairs though--sortof in the ground. What do I need downstairs to give printer access to my laptop wirelessly? One thing I can't do in this solution is have a computer on downstairs, so I would think that would eliminate a usb solution.

  • File/folder Write/Delete wise, is my server secure?

    - by acidzombie24
    I wanted to know if someone got access to my server by using a nonroot account, how much damage can he do? After i su someuser I used this command to find all files and folders that are writeable. find / -writable >> list.txt Here is the result. Its most /dev/something and /proc/something and these /var/lock /var/run/mysqld/mysqld.sock /var/tmp /var/lib/php5 Is my system secure? /var/tmp makes sense but i am unsure why this user has write access to those folders. Should i change them? stat /var/lib/php5 gives me 1733 which is odd. Why write access? why no read? is this some kind of weird use of a temp file?

  • How can give privilege for DB to a user [ ERROR 1044 (42000): Access denied for user ''@'localhost']

  • How to limit access to Exchange 2003 Mobile Actviesync server by user?

    - by micilin
    So I was asked to set up an Exchange Activesync mobile gateway. That's done. It's a separat eExchange 2003 front-end server configured for SSL, and I've put an off-domain ISA server in front of it. Now I'm being asked to limit which users can connect to it. By default an Exchange front-end server allows any user who has a mail account to connect to the front -end server. So I'm looking at the permissions on the various IIS sites/apps on the server, but I know that it's easy to break Exchange Front-end server perms. So I've got the following in IIS: Exadmin Exchange EchWeb Microsoft-SErver-ActiveSync MobileAdmin OMA And a couple of others that I dont think are relevant. Can I change the permissions on one of these to restrict who can connect to Activesync? As a bonus: Can I do it in a way that does not affect ordinary browser based Exchange Access? Thanks in Advance!!

  • Can a cur file have an alpha map (for high quality transparency)?

    - by Codemonkey
    I want to convert this Heroes of Newerth cursor into a cur file so I can use it as a cursor on windows and on my website. The cursor is now in a PNG file with an alpha map, and I have so far been unsuccessful in converting it to a cur file. The things I've tried is using the Photoshop cursor plugin to simply save the png as a cur. The result was a working cur file with a white background instead of a transparent one. I've also tried painting the background pure green (0, 255, 0) and saving as a cur file, in which case the background was still green when I tried using it as a windows cursor. I've also tried what's been mentioned in a few tutorials, which is selecting the area I want transparent and saving the selection in Photoshop (it then ends up as a new channel). So I selected the cursor and inverted the selection and saved it. The result was a bit odd. Instead of a transparent background, I now get a background that inverts the colours behind it, just like the "Windows inverted" mouse scheme. So is there any way to accomplish what I'm trying to do?

  • Office 2010 & Windows 7 - 'File' is currently in use. Try again later

    - by thing2k
    The issue: when saving a document from either Word, Excel or PowerPoint 2010, every so often it will show the message 'file' is currently in use. Try again later. We started our rollout of Windows 7 beginning of this year, and this issue was infrequent, but is now affecting enough people to be a problem. Usually, if you clear the alert, then save again, it works fine, though only in Word or Excel. Annoyingly, PowerPoint has a bad habit of changing the file to read-only after the error. So the only choice is to save to a new file name. The issue seems to only happen to files in the user's My Documents, which is a redirection folder from their HomeShare. The HomeShares are spread across 3 different file servers, 2 Windows 2003 and 1 Windows 2008 R2. Has anyone seen this issue and know how to fix it?

  • How can I crop every page of a large PDF file?

    - by Andrew
    I have a 1300 page PDF file of a scanned book that was unfortunately not cropped when scanned. The actual book page dimensions are around 6x9", but each scanned page is 8.5x11", the size of the scanner bed. For much smaller PDF files I could throw it into Photoshop and crop the page, but this is a huge file. What is the best way to losslessly crop all of the pages of the file, in either Windows or OS X?

  • How to allow Mac OS X's native Apache/PHP installation to access WebServer directories?

    - by Martin Bean
    I have a problem bugging me with Mac OS X's native Apache/PHP installation. With my PHP scripts, I have to alter the file permissions on each folder I want to access. For example, in an upload script I would have to set the destination directory to 'read & write' for the group 'everyone'. However, I believe this is not the best practice and would like all of my directories to be readily writable to PHP. My scripts are stored in /Library/WebServer/Documents/, which is Mac OS X's default directory to serve web pages locally.

  • How do I put a url n a text file and change it to html - making it a shortcut

    - by VISQL
    I've forgotten how to do this. In Windows, you can create a new text document "blah.txt" Inside blah, you can enter a url like http://kongregate.com Then.....??? I forget this step Then you change the file extension of the file to "blah.html" When you double click the file, it acts as a shortcut/hyperlink and takes you to the url you entered in the text file. Can someone tell me what the missing step it? There is something else I need to enter with the url, but I don't know what it is.

  • Tools to extract text from powerpoint pptx in linux?

    - by felix
    Any there any linux tools that will extract the text from a Powerpoint pptx file? I tried catppt but it just returns file.pptx is not OLE file or Error. abiword --to=txt file.pptx also returns an empty text file. I can open the file in libreoffice but it doesn't seem to have an "export as text" option. As a guess I also tried libreoffice --headless --convert-to txt:Text file.pptx but that doesn't even return an empty file.

  • In VirtualBox, how can I access host localhost from guest (Visual Studio Dev Server from IE7 testing VM)?

    - by Seth
    Host OS is Win7 running MyApp in the Visual Studio Development Server, bound to localhost:51227, VM is VirtualBox configured with NAT. Guest OS is Win XP with IE7 installed. My goal is to debug MyApp (running on host) from within IE7 (running on guest). Visual Studio Development server only binds to the loopback network device (i.e. localhost). It does not bind to the external IP address of my host. I've tried access 10.0.2.2:51227 from IE7 on the guest (and confirmed that 10.0.2.2 is the gateway address using ipconfig), but it appears that 10.0.2.2 binds to the external IP of the Host, NOT the loopback IP (localhost), so this does not work. Any suggestions?

  • Know any file compare utility for chunks of text?

    - by Belun
    Is there any file-compare utility-software that can help me compare chunks of text from two text files ? As in, I want to know what chunks of text that are in one file can be found again in the second file. What I need to do is more like a 'compare and search' operation, not just a compare line by line. I need this for finding common errors in application logs. Eg., I have a Java application and logs from two different days. I want to find out which stack-traces (that are actually chunks of text inside a text file) are common to both days.

  • Do memory cards have any max file size limitation?

    - by Dmitriy R
    I am not sure where to ask this question, so perhaps it is physical limitation. I have a 8 GB flash micro SD memory card. When I copy any file size of up to few gigabytes, copying happens normally. But if I am trying to copy file over 4 GB file, then the system tells me like insufficient memory on card, although 8 GB is available. So perhaps only 32 bit address is used for keeping size of file in micro SD card, or is my micro SD defective?

  • Ubuntu: On a network with many clients there are two machines that can't access the web via a browser at the same time

    - by ChrisInCambo
    Ok I'm pulling my hair out over this one. We have a wireless network with many clients all working well except two Ubuntu clients running 10.10 that can't access the internet via a browser at the same time. They can both still ping, use Skype etc but can't browse. As soon as the one that can browse exits the network browsing returns for the other and vice versa. As ping and Skype was working I assumed some kind of DNS problem but moving over to OpenDNS didn't solve it, nor did restarting networking or using wired rather than wireless. We also switched out the router, and it still persisted so I'm sure this isn't a network issue. The two clients are both laptops and work fine together on a wireless network at another office (which we don't control). I'm thinking something must be cached from the other network they both use that's causing this but have no idea what. Does anyone have any ideas? I just don't know where to go from here.

  • "bin/sh: can't access tty; job control turned off” error when running shellcode"

    - by Nosrettap
    I'm writing shellcode to exploit a buffer overflow vulnerability on a server. To do so I have port binding shellcode that I send to the server and then I run (from a linux terminal) the command telnet serverAdress 4444 where 4444 is the port which I have opened up. The hope is that I will receive a shell back that I can use to execute commands. However, I always end up with the command bin/sh: can't access tty; job control turned off I can't change any of the server code, and I believe the shellcode is correct because I got it from this website (http://www.tsirogiannis.com/exploits-vulnerabilities-videos-papers-shellcode/linuxx86-port-binding-shellcode-xor-encoded-152-bytes/). From my research, it appears that this may have to do with the mode that my terminal is running in (something called interactive mode...or something like that). All computers involved are linux machines and the machine that I am on is running the latest version of Ubuntu. Any ideas what this job control error means and how I can fix it?

  • Can I stop SharePoint from prompting during file edit?

    - by uSlackr
    We use a SharePoint 2007 site internally with Office 2010. Whenever I open a Word document to edit it, I get a prompt saying: Some files can harm your computer. If the file information below looks suspicious, or you do not fully trust the source, do not open the file. I've been unable to find a reliable answer around the web. Some suggested using the Windows File Types dialog to remove the prompt on download option, but this dialog is not available in Windows 7.

  • Why am I unable to access the network shares on my own computer?

    - by DoomStone
    I am having some problems with media center computer, with Windows 7 on it. The computers IP address is 192.168.1.13, and another computer can without any problem navigate to \\192.168.1.13, but the computer itself can not. Neither \\servername nor \\localhost. If I reboot the computer a couple of times, it will work again, but this is a big problem as my computer cleans my media center library on boot and there, if it can not access \\192.168.1.13, it will think that all the files have been removed and therefore delete them from the database. I really have no idea on where to start with this problem, but if anyone has tried this before and fixed it, I would be very happy, as it would save me from having to reinstall the whole system.

  • Best way to restrict FTP access to a single directory?

    - by John Debs
    I have a VPS running Ubuntu 10.04, and I'd like to give someone SFTP access to a single directory, but prevent them from seeing anything else on the system. What's the best way to pull this off? I considered removing "everyone" permissions from everything on the system, but that seems like a really blunt tool for this problem (and one that'll cause other issues) - I'm hoping there's a better option here. Edit: I appreciate the answers! (And I learned a bunch reading/researching through them). I ended up finding and using this guide from Linode as it spelled all the steps: http://library.linode.com/security/sftp-jails/

  • Under *nix, how can I find a string within a file within a directory ?

    - by roberto
    Hi all. I'm using ubuntu linux, and I use bash from with a terminal emulator every day for many tasks. I would like to know how to find a string or a substring within a file that is within a particular directory. If I was knew the file which contained my target substring, I would just cat the file and pipe it through grep, thus: cat file | grep mysubstring But in this case, the pesky substring could be anywhere within a known directory. How do I hunt down my substring ?
