  • How do I hook into Tar with BASH?

    - by orb
    Long Story Short I am working with Tar archives that contain PNG images in base64 encoding. I would like to use BASH (or whatever else works) to hook into the extraction function of Tar to decode PNG images from base64 encoding to standard PNG encoding after the files are unpacked. A simple cat $input-file | base64 -d >$output-file will successfully decode the images. Is there a way I can hook into tar -xf so that users do not have to do any (or minimal) extra work to decode the images? In the GNU Tar documentation (http://www.gnu.org/software/tar/manual/html_chapter/Backups.html#SEC97) I found that there are in fact variables reserved to hold the names of functions I desire to be hooked into various moments in Tar program execution. However, the documentation explains that these variables, along with other variables that can be set to configure Tar, are located in a file named backup-specs. Unfortunately, the path to this file is not given. Further, running sudo find / -name backup-specs tells me that this file is not present on my Ubuntu version 13.04 system. Background Information not included in the Long Story Short I have been working on a browser-based (WebGL) particle effect creation application (http://www.particleeffect.org), (https://github.com/cgrabowski/webgl-particle-effect-editor), (https://github.com/cgrabowski/webgl-particle-effect). I have began to write a client-side-only solution for saving and loading effect data as a tar archive. However, since client-side JavaScript has limited capability to process binary data, the images used as textures in the effect are saved with base64 encoding. I have been able to implement saving effect data as a Tar archive (haven't pushed that to Github yet). However, the images present in said Tar archive cannot be manipulated unless they are decoded from base64 encoding.

  • Good scanner to buy as of January 2010

    - by AlexV
    I'm planning to buy a scanner soon and since I didn't purchased one in years I wanted to know which brand / models are the "best". The ability to scan negatives is a nice to have but not 100% required. If you are specifing a model in particular, plase note that it must work under 64-bit OS (I'm using Windows 7 Ulitmate 64-bit). I'm not looking for a all-in-one solution like scanner/fax/printer. I want to use this to scan "old" photos from the non-digital era :) And sometimes to scan magazines and books. I am located in Canada it would be nice if your suggestion is available here. I usually buy online at NCIX and DirectCanada if it can help you see what's available there. Edit: My search leaded me to 2 particular models. I hesitate between Canon CanoScan 8800F and Epson V600. Anyone have good/bad words on either of them?

  • Combo ports and SFP

    - by Tahir
    I have Netgear GSM7324s prosafe switch. Switch has 24x1G ports. 4 ports are labeled as combo ports while 2 are labeled as SFP ports. I connected 2 PCs (each having 1gig and 10Gig NICs), with the switch using 1 & 10 Gig cables. Whenever, I ping the PCs the pinging is not working. As soon as, I removed the 10G cables, the ping starts working. Can someone please explain that what's going on. Also it would be very helpful if you can tell me the concept of combo ports, SFP ports in easy words?

  • Convert svn repository to hg - authentication fails

    - by Kim L
    I'm trying to convert an existing svn repository to a mercurial repo with the following command hg convert <repository> <folder> My problem is that the svn repository's authentication is done with p12 certificates. I'm a bit lost on how to configure the certificate for the hg client so that I can pull the svn repo and convert it. Currently, if I try to run the above command, I get initializing destination hg-client repository abort: error: _ssl.c:480: error:14094410:SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure In other words, it cannot find the required certificate. The question is, how do I configure my hg client so that it can use my certificate? I'm using the command line hg client on linux.

  • Problem with reading file line-by-line

    - by Maulrus
    I'm trying to complete an exercise to write a program that takes the following command line arguments: an input file, an output file, and an unspecified number of words. The program is to read the contents of the input file line by line, find for each word given which lines contain the word, and print the lines with their line number to the output file. Here's my code: #include <iostream> #include <fstream> #include <string> #include <sstream> using namespace std; int main(int argc, char* argv[]) { if (argc < 4) { cerr << "Error #1: not enough arguments provided\n"; return 1; } ifstream in(argv[1]); if (!in.is_open()) { cerr << "Error #2: input file could not be opened\n"; return 2; } ofstream out(argv[2]); if (!out.is_open()) { cerr << "Error #3: output file could not be opened\n"; return 3; } ostringstream oss; for (int i = 3; i < argc; ++i) { int k = 0; string temp; oss << argv[i] << ":\n\n"; while (getline(in, temp)) { ++k; unsigned x = temp.find(argv[i]); if (x != string::npos) oss << "Line #" << k << ": " << temp << endl; } } string copy = oss.str(); out << copy; in.close(); out.close(); return 0; } If I try to run that, I get the predicted output for the first word given, but any words following it aren't found. For example, for the source code above will give the following output: in: Line #1: #include <iostream> Line #2: #include <fstream> Line #3: #include <string> Line #4: #include <sstream> Line #5: using namespace std; Line #7: int main(int argc, char* argv[]) { Line #12: ifstream in(argv[1]); Line #13: if (!in.is_open()) { Line #14: cerr << "Error #2: input file could not be opened\n"; Line #22: ostringstream oss; Line #23: string temp; Line #24: for (int i = 3; i < argc; ++i) { Line #26: int k = 0; Line #28: while (getline(in, temp)) { Line #30: unsigned x = temp.find(argv[i]); Line #31: if (x != string::npos) Line #32: oss << "Line #" << k << ": " << temp << endl; Line #35: string copy = oss.str(); Line #37: in.close(); out: That is, it'll find all the instances of the first word given but not any following. What am I doing wrong here?

  • ft_stopword_file not picked up

    - by Alex Holsgrove
    I have a VPS server with a company called Webfusion. I want to remove some or all of the FULLTEXT stopwords because some specific words needs to be searchable with my DB content. I opened /etc/mysql/my.cnf and added the line ft_stopword_file="". I restarted the mysql service, ran a repair table and then tried my MATCH query with no success. I ran SHOW VARIABLES LIKE 'ft_%' and it simply shows (built-in) next to the stopword file. I am running WAMP on my workstation, and whilst I realise this isn't configured the same as a commercial VPS, the above method worked just fine. Couple someone please offer some guidance?

  • Google Search w/ Chrome Incognito w/ Gnome Do

    - by jrc03c
    I've installed Google Chrome as my default browser in Ubuntu, and recently installed Gnome Do and enabled the Google Search plugin. The Google Search from Gnome Do works exactly as expected but for one thing: Chrome (which is typically set to open in "incognito" mode) does not open in "incognito" mode. The shortcuts on my desktop, taskbar, and menus all have the --incognito flag attached (which works just fine), but the browser refuses to open in this mode when launched from Gnome Do. Any suggestions? Also, please note the settings for the Google Search plugin in Gnome Do: It's obvious that Gnome Do just passes the Google Search blindly to the default browser. In other words, there are no configurable settings specifically for Chrome. Any thoughts?

  • What's the best self-tracking software for Linux?

    - by trench
    I'm looking for a way to track myself and receive quality data upon which I can write future scripts/programs. For example, I use Google Reader a lot. I'd like to track the hrefs that garner my clicks. Further, I'd like to drop all of the words of each href into a database where they can be stacked in a hierarchical manner. At the end of the week I want to know that "Ubuntu" garnered 448 clicks and "Cheetos" garnered 2. :) That's just one example... I'd like this tracking and data-collecting to extend beyond my browser. I know writing something to do this myself wouldn't be too awfully difficult but if something already exists I'd happily use it. Thanks in advance. Primary OS: Ubuntu 10.04

  • Server hard disk read speed and client download speed, is there a connection? [closed]

    - by Mywiki Witwiki
    Ok so a client's download speed is only as fast as a server's upload speed, and vice versa. Based on the answers to this post: Does upload speed depend upon download speed of the server? In other words, the data transfer rate between the two computers is only as fast as the speed of the "bottleneck". Let's pretend the two computers are in two different networks and both have 100Mbps internet connection. Ben wants a copy of a file in Mark's computer hard disk with 30Mbps read speed. Does this mean that Ben can download the file at a speed of around 30Mbps only, despite having an internet connection faster than 30Mbps?

  • Can't connect to domain computers until reboot

    - by thealliedhacker
    I have a domain with about 300 Windows 7 and XP machines, with the domain controllers running Server 2003. Sometimes, I lose the ability to communicate/authenticate with some of the machines until I reboot my computer. This also happens from other computers and regardless of user account and operating system. In other words, say I'm on ComputerA, and I can't connect to ComputerX. I can go to ComputerB and connect to ComputerX, but ComputerB may not be able to connect to ComputerY. If you reboot ComputerA, then it will be able to connect to ComputerX again. Here are some messages from various utilities: sc: [SC] OpenSCManager FAILED 1722: The RPC server is unavailable. mmc (compmgmt.msc): Computer (computer name) cannot be managed. The network path was not found. explorer (\\computer): Windows cannot access \\(computer name). ping: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss) / Average = 1ms

  • how insecure is my short password really?

    - by rika-uehara
    Using systems like TrueCrypt, when I have to define a new password I am often informed that using a short password is insecure and "very easy" to break by brute-force. I always use passwords of 8 characters in length, which are not based on dictionary words, which consists of characters from the set A-Z, a-z, 0-9 I.e. I use password like sDvE98f1 How easy is it to crack such a password by brute-force? I.e. how fast. I know it heavily depends on the hardware but maybe someone could give me an estimate how long it would take to do this on a dual core with 2GHZ or whatever to have a frame of reference for the hardware. To briute-force attack such a password one needs not only to cycle through all combinations but also try to de-crypt with each guessed password which also needs some time. Also, is there some software to brute-force hack truecrypt because I want to try to brute-force crack my own passsword to see how long it takes if it is really that "very easy".

  • Send encrypted mail using GPG by command-line?

    - by Mohammad AL-Rawabdeh
    A few days ago I asked about how I can secure email and many people advised me to use PGP tool, and I read about it and I use it. Now I want to write a batch file to send encrypted email with attachments. I know how I can generate key, exchange key with other side and encrypt email with PGP mail but until now I don't know how I can integrate PGP tool with my mail and how I can send the encrypted email. In other words, how can I send encrypted email that encrypts with PGP tool to other side by command line (batch file)?

  • DSL vs Cable latency

    - by tovmeod
    currently I have a 10Mbps DSL line and I'm thinking to switch to a cable since they got 100Mbps for a little less than double the price I'm paying for 10Mbps. In other words the cable company is offering 100Mbps for the price of 20Mbps DSL. Since 10Mbps is more than enough for me I am worried about the latency, I saw this that is just a guy experiment, that shows that cable and DSL are the same in practical terms, and this but I couldn't grasp it, not sure if it is helpful. So my question is if there's any practical difference between cable and DSL, mainly in latency terms but I would be also interested in other advantages/disadvantages. This is for my home connection, I work from home but I don't run any server, I most of the time code, skype and eventually game.

  • Is zip's encryption really bad?

    - by Nifle
    The standard advice for many years regarding compression and encryption has been that the encryption strength of zip is bad. Is this really the case in this day and age? I read this article about WinZip (it has had the same bad reputation). According to that article the problem is removed provided you follow a few rules when choosing your password. At least 12 characters in length Be random not contain any dictionary, common words or names At least one Upper Case Character Have at least one Lower Case Character Have at least one Numeric Character Have at least one Special Character e.g. $,£,*,%,&,! This would result in roughly 475,920,314,814,253,000,000,000 possible combinations to brute force Please provide recent (say past five years) links to back up your information.

  • Configure IIS Web Site for alternate Port and receive Access Permission error

    - by Andrew J. Brehm
    When I configure IIS to run a Web site on Port 1414, I get the following error: --------------------------- Internet Information Services (IIS) Manager --------------------------- The process cannot access the file because it is being used by another process. (Exception from HRESULT: 0x80070020) However, as according to netstat the port is not in use. Completely aside from IIS, I wrote a test program (just to open the port and test it): TcpListener tcpListener; tcpListener = new TcpListener(IPAddress.Any, port); try { tcpListener.Start(); Console.WriteLine("Press \"q\" key to quit."); ConsoleKeyInfo key; do { key = Console.ReadKey(); } while (key.KeyChar != 'q'); } catch (Exception ex) { Console.WriteLine(ex.Message); } tcpListener.Stop(); The result was an exception and the following ex.Message: An attempt was made to access a socket in a way forbidden by its access permissions The port was available but its "access permissions" are not allowing me access. This remains after several restarts. The port is not reserved or in use as far as I know and while IIS says it is in use, netstat and my test program say it is not and my test program receives the error that I am not allowed to access the port. The test program ran elevated. The IIS Site is running MQSeries, but the MQ listener also cannot start on port 1414 because of this issue. A quick search of my registry found nothing interesting for port 1414. What are socket access permissions and how can I correct mine to allow access?

  • Just one client bound to address and port: does it make a difference broadcast versus unicast in terms of overhead?

    - by chrisapotek
    Scenario: I am implementing failed over for a network node, so my idea is to make the master node listens on a broadcast ip address and port. If the master node fails, another failover node will start listening on this broadcast address (and port) and take over. Question: My concern is that I will be using a broadcast IP address just for a single node: the master. The failover node only binds if the master fails, in other words, almost never. In terms of network/traffic overhead, is it bad to talk to a single node through a broadcast address or the network somehow is smart enough to know that nobody else is listening to this broadcast address and kind of treat it as a unicast in terms of overhead? My concern is that I will be flooding my network with packets from this broadcast address even thought I am just really talking to a single node (the master). But I can't use unicast because the failover node has to be able to pick up the master stream quickly and transparently in case it fails.

  • Unable to connect SQL Server instance from Visual Studio 2008 Version 9.0

    - by salvationishere
    I am getting the below error from VS on an 32-bit XP Professional server even though I set Tools-Options-Database Tools-Data Connections to "SIDEKICK", which is the name of my computer. In other words SIDEKICK should default to the full SQLSERVER. In other words, I want VS to use SQLSERVER instead of SQLSERVER EXPRESS. And I can clearly see my database both from VS in the Server Explorer and also in SSMS 2008. Furthermore, I can view the tables of this database in Server Explorer from VS. I do not get any build errors. And it looks like all of the naming is consistent in my web.config file. I am developing my website according to a Microsoft tutorial, so I should not be getting an error. Yet I get the following exception when I run this code below: CreateAccounts.aspx.cs file protected void CreateAccountButton_Click(object sender, EventArgs e) { MembershipCreateStatus createStatus; //This line below is where the exception occurs MembershipUser newUser = Membership.CreateUser(Username.Text, Password.Text, Email.Text, passwordQuestion, SecurityAnswer.Text, true, out createStatus); And here is what the exception looks like: System.Web.HttpException was unhandled by user code Message="Unable to connect to SQL Server database."

  • Alternate port numbers for Supermicro IPMI View software

    - by MC9000
    I'm using the IPMI View software to manage a SuperMicro server but would like to use alternate port #s within the program itself. In other words - If I use the web browser, it defaults to port 80 - While I can, say change that port to 12345 (or whatever) and type the IP address into the browser (like http://xxx.xxx.xxx.xxx:12345 ) that works just fine. However, in IPMIView, it will assume port 80 and load the browser with the IP (which, naturally, won't work, so I have to manually type in the alternate port #). I can deal with that. The clincher is if I use a port other than 623 for management - (say 55623 for example), the IPMIView will not find it. Same goes for the iKVM port #. Is there some place to specify this (to tell IPMIView to use the alternate port numbers), like a settings file? I'm running this from a Windows client.

  • How can I customize the notification from Google Notifier and Google+Growl?

    - by Philip
    As best I can tell, Google+Growl just makes the Google Notifier growl the notification instead of displaying its own. The GrowlMail plugin lets you configure what info is displayed upon receipt of a new message. Is there a way to configure what is displayed by the Google Notifier a la GrowlMail--in other words, to choose that I just want to see e.g. that there is a new message and the time, but not the sender or body, etc. etc....? Thanks!

  • Hugepages not utilized by MySQL 5.0, CentOS 5

    - by TechZilla
    I've set up Hugepages, but i'm not seeing any of them reserved. Have I missed a step, or for some particular reason, is MySQL is unable to utilize the Hugepages? I have not created a mount of hugetlbfs, although from what I read, MySQL would not call pages in such a manner. If I'm wrong, please let me know, as that would be a trivial solution. Almost all my MySQL tables are using InnoDB. NOTE: I created a hugetlbfs, no change as expected. Is it possible that rebooting would rectify this situation? I would not want to go through the procedure, as this is high availability, but would do so if necessary. This is the configurations, which I believe are relevant. /etc/sysctl.conf ... ## Huge Pages vm.nr_hugepages = 4096 vm.hugetlb_shm_group = 27 ## SHM kernel.shmmax = 34359738368 kernel.shmall = 8589934592 ... /etc/security/limits.conf ... mysql soft nofile 12888 mysql hard nofile 51552 @mysql soft memlock unlimited @mysql hard memlock unlimited /etc/my.cnf [mysqld] large-pages ... grep Huge /proc/meminfo HugePages_Total: 4096 HugePages_Free: 4096 HugePages_Rsvd: 0 Hugepagesize: 2048 kB id mysql uid=27(mysql) gid=27(mysql) groups=27(mysql) context=root:system_r:unconfined_t:SystemLow-SystemHigh tail -6 /var/log/mysqld.log InnoDB: HugeTLB: Warning: Failed to allocate 1342193664 bytes. errno 12 InnoDB HugeTLB: Warning: Using conventional memory pool 120808 15:49:25 InnoDB: Started; log sequence number 0 1729804158 120808 15:49:25 [Note] /usr/libexec/mysqld: ready for connections.

  • Sparing level on HP EVA 4000

    - by Samuel
    One of the disks of our EVA4000 died today. This diskgroup (all volumes vraid5 with sparing level 1 and almost no space left for more volumes, 1TiB drives) is being rebuilt with "spare space" right now, and it will take at least 15 hours to do the leveling/rebuilding. We can't get a new disk until Friday. So, the question is, what would happen if another disk dies before the leveling completes? Would we lose data? And after that, how many aditional disks could die before losing data? 1 or 2? In "usual" RAID, we would be vulnerable to data loss while the rebuild takes place, but in this case the space reserved for sparing is two times the size of the bigger disk, so at the very least the effect should be the same of having two spares. Thanks in advance. Update: I have found some interesting threads about this question but still can't answer to this question, so I'm starting a bounty. http://blog.thestoragearchitect.com/2008/10/27/understanding-eva/ http://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&url=http%3A%2F%2Fwww.experts-exchange.com%2FStorage%2FStorage_Technology%2FQ_25548177.html (Expert Exchange question from google).

  • Solaris disk I/O spike... which monitoring tools do I need?

    - by bonez05
    Hi all, My Solaris 10 websever / database server disk io keeps spiking at intermittent times. Using iostat -xtc 5 the reads / sec will jump from 3.0 to 1450.0 and %busy will jump to 98% The apache access log doesn't indicate anything out of the ordinary. In other words, requests aren't any higher than usual. top doesn't generate anything useful. The cpu usage is fine with mysql using about 20% and nothing else to speak of really. What monitoring tool should I be using to see what process is using excessive disk I/O? or if there are any other suggestions I'm all ears. Thanks

Excluding: /sys/kernel/debug /sys/kernel/security /sys /proc /dev/pts /dev /dev /media /mnt /proc /sys /etc/udev/rules.d/70-persistent-net.rules /etc/udev/rules.d/z25_persistent-net.rules /mnt/image /mnt/img-mnt 1+0 records in 1+0 records out 1048576 bytes (1.0 MB) copied, 0.00677357 s, 155 MB/s mkfs.ext3: option requires an argument -- 'L' Usage: mkfs.ext3 [-c|-l filename] [-b block-size] [-f fragment-size] [-i bytes-per-inode] [-I inode-size] [-J journal-options] [-G meta group size] [-N number-of-inodes] [-m reserved-blocks-percentage] [-o creator-os] [-g blocks-per-group] [-L volume-label] [-M last-mounted-directory] [-O feature[,...]] [-r fs-revision] [-E extended-option[,...]] [-T fs-type] [-U UUID] [-jnqvFKSV] device [blocks-count] ERROR: execution failed: "mkfs.ext3 -F /mnt/image -U 1c001580-9118-4a50-9a25-dcf02be6d25f -L " So mkfs.ext3 wants -L, which is a volume name. But ec2-bundle-vol doesn't seem to take in a volume name as an argument, and the docs (http://docs.amazonwebservices.com/AmazonEC2/gsg/2006-06-26/creating-an-image.html) don't seem to think one should be needed. Certainly their sample command: # ec2-bundle-vol -d /mnt -k ~root/pk-HKZYKTAIG2ECMXYIBH3HXV4ZBZQ55CLO.pem -u 495219933132 -s 1536 doesn't specify anything. So... any help? What am I missing?

  • How do I add color syntax highlighting to GNU emacs?

    - by Alex Reynolds
    I have two versions of emacs available to me on a locked workstation: $ /usr/local/bin/emacs --version GNU Emacs 22.3.1 $ /usr/bin/emacs --version GNU Emacs 21.4.1 In both cases, my terminal type is xterm when I run either version of emacs. When I run the v21 version of emacs, I get syntax coloring for Perl, HTML, and other modes. When I run the v22 version, I do not get syntax coloring. I would like to migrate from the v21 version because the combination of v21 emacs, GNOME Terminal and GNU Screen is eating Ctrl-arrow key chords, which prevents me from moving quickly between words. (OS X Terminal and GNU Screen do not have this issue.) The v22 version allows use of Ctrl-arrow key combinations with GNOME Terminal and GNU Screen. How do I fix the v22 version (or ask my sys admin to fix) so that it once again highlights syntax and allows me to use Ctrl-arrow key combinations?
