  • Problem Making C++ script

    - by Abs
    Hello all, I am not sure if I can post this sort of question (apologies in advance) but I am trying to build something from this blog post. # mkdir wkthumb # cat > wkthumb.cpp # qmake -project # qmake && make # ./wkthumb I have no experience with this, but I download all the files needed in the directory wkthumb using git. I have gone inside this directory and tried to execute cat > wkthumb.cpp - this just hangs for me. In addition, I thought cat was supposed to be used like this: cat file1.txt file2.txt > file3.txt? The above is blank with the first arguments? I am using Fedora Core 10.

  • Implemenation of a pass through file system

    - by user3491505
    Can anyone give me inputs on how to implement a pass through filesystem using fuse?? What I mean by this is that you mount your FUSE file system somewhere (say in /mnt) such that the FUSE file system passes all filesystem calls to some other place (say /home/user). For example, when you go into the /mnt directory and run "ls", this would pass the file system calls to execute ls through and run them on /home/user, such that the directory contents of /home/userwould be listed

  • When is a program limited by the memory bandwidth?

    - by hanno
    I want to know if a program that I am using and which requires a lot of memory is limited by the memory bandwidth. When do you expect this to happen? Did it ever happen to you in a real life scenario? I found several articles discussing this issue, including http://www.cs.virginia.edu/~mccalpin/papers/bandwidth/node12.html http://www.cs.virginia.edu/~mccalpin/papers/bandwidth/node13.html http://ispass.org/ucas5/session2_3_ibm.pdf The first link is a bit old, but suggests that you need to perform less than about 1-40 floating point operations per floating point variable in order to see this effect (correct me if I'm wrong). How can I measure the memory bandwidth that a given program is using and how do I measure the (peak) bandwidth that my system can offer? I don't want to discuss any complicated cache issues here. I'm only interested in the communication between the CPU and the memory.

  • Graphical patch utility

    - by Demiurg
    I have a kernel patch for a slightly different kernel version then the one I'm trying to patch. Needless to say, the patch partially fails. I can certainly fix it manually, but I was wondering maybe there is a graphical patch utility that can be used to resolve the conflicts.

  • task_current redundant field

    - by user341940
    Hi, I'm writing a kernel module that reads from a /proc file. When someone writes into the /proc file the reader will read it, but if it reads again while there is no "new" write, it should be blocked. In order to remember if we already read, i need to keep a map of the latest buffer that process read. To avoid that, I was told that there might be some redundant field inside the current- (task_struct struct) that i can use to my benefits in order to save some states on the current process. How can I find such fields ? and how can i avoid them being overwritten ? I read somewhere that i can use the offset field inside the struct in order to save my information there and i need to block lseek operations so that field will stay untouched. How can I do so ? and where is that offset field, i can't find it inside the task_Struct. Thanks and I need to save for each process some information in order to map it against other information. I can write a ma

  • Using directory traversal attack to execute commands

    - by gAMBOOKa
    Is there a way to execute commands using directory traversal attacks? For instance, I access a server's etc/passwd file like this http://server.com/..%01/..%01/..%01//etc/passwd Is there a way to run a command instead? Like... http://server.com/..%01/..%01/..%01//ls ..... and get an output? EDIT: To be clear here, I've found the vuln in our company's server. I'm looking to raise the risk level (or bonus points for me) by proving that it may give an attacker complete access to the system

  • Same memory space being allocated again & again while using malloc()

    - by shadyabhi
    In each loop iteration, variable j is declared again and again. Then why is its address remaining same? Shouldn't it be given some random address each time? Is this compiler dependent? #include<stdio.h> #include<malloc.h> int main() { int i=3; while (i--) { int j; printf("%p\n", &j); } return 0; } Testrun:- shadyabhi@shadyabhi-desktop:~/c$ gcc test.c shadyabhi@shadyabhi-desktop:~/c$ ./a.out 0x7fffc0b8e138 0x7fffc0b8e138 0x7fffc0b8e138 shadyabhi@shadyabhi-desktop:~/c$

  • Use sudo su - <username> to access the <username's> account but sudo su - shouldn't be possible with a sudo user

    - by Winnie
    There is a requirement I got. My sudo users (for which their entry in sudoers file) should be able to access other user's account say Oracle using following command: sudo su - Oracle The above should work with giving current users password. But if the same user is firing the following command, sudo su - it shouldn't work and thus root access shouldnt be given to current user. I am not using su because because i dont want current user to know the credentials of other user(root,Oracle etc.). Can anyone please help me . Its urgent...

    Anybody know if it is possible that when making a tar + gzip through 'tar c ...' command if the relative paths will be ignored upon expanding. e.g. tar cvf test.tgz foo ../../files/bar and then expanding the test.tgz with: tar xvf test.tgz gives a dir containing: foo files/bar i want the dir to contain the files foo bar is this possible?

  • Methods of sending web-generated config files to servers and restarting services.

    - by JPG
    Hi, We're writing a web-based tool to configure our services provided by multiple servers. This includes interfaces configuration, dhcp configs etc. etc. Having configs in database and views that generate proper output, how to send it/make it available for servers? I'm thinking about sending it through scp and invoking reload command to services through ssh. I'm also thinking about using Func to do all the job, as this is Python tool and will seemingly integrate with python-based (django) config tool. Any other proposals?

  • Creating a Custom Ubuntu Daemon

    - by Chris S
    What's the "correct" way to create a custom daemon in Ubuntu, that will start at boot time and be controllable by Ubuntu's standard daemon start/stop commands? Can I just copy and paste one of the scripts in /etc/init.d or do I need to "register" the daemon somewhere else?

  • How to get line count from variable (from MYSQL query)?

    - by Mint
    My problematic code: testMYSQL=`mysql -u $mysqlUser -p$mysqlPass -h $mysqlHost --skip-column-names --batch -D $mysqlDB -e "SELECT $select FROM $mysqlTable WHERE nameTXT='test';"` $testMYSQL now contains: test test test Then I do: TEST=$(echo $testMYSQL | wc -l) echo "$TEST" I would of thought that would work, but it doesn't, it returns 1 But if I put this into $testMYSQL: "test\ntest\ntest" it will say 3… Whats going on here? does MYSQL not use new lines? PS, I know I can use a for loop to loop though the lines then count up the lines that way, but I was hoping for a simpler solution like wc

  • Saving information in the IO System

    - by djTeller
    Hi Kernel Gurus, I need to write a kernel module that simulate a "multicaster" Using the /proc file system. Basically it need to support the following scenarios: 1) allow one write access to the /proc file and many read accesses to the /proc file. 2) The module should have a buffer of the contents last successful write. Each write should be matched by a read from all reader. Consider scenario 2, a writer wrote something and there are two readers (A and B), A read the content of the buffer, and then A tried to read again, in this case it should go into a wait_queue and wait for the next message, it should not get the same buffer again. I need to keep a map of all the pid's that already read the current buffer, and in case they try to read again and the buffer was not changed, they should be blocked until there is a new buffer. I'm trying to figure it there is a way i can save that info without a map. I heard there are some redundant fields inside the I/O system the I can use to flag a process if it already read the current buffer. Can someone give me a tip where should i look for that field ? how can i save info on the current process without keeping a "map" of pid's and buffers ? Thanks!

  • If I start learning C on Ubuntu will it give me an edge when I start learning Objective-C later this

    - by Anonymous
    I know Ruby right now, however I want to learn a new language. I am running Ubuntu 10.04 right now but I am going to get a Mac later this summer. Anyways I want something more for GUI development. I was wondering if I should learn C on Ubuntu right now, and then learn Objective-C when I get an iMac? Will learning C give me an edge? Or should I just learn Python on Ubuntu and then learn Objective-C when I get a new computer? Please give me your opinions! Thanks!

  • Strange mod_rewrite problem; Website works partially

    - by Camran
    I have Ubuntu 9.10 Server... I need to get mod_rewrite working... the mod_rewrite module IS LOADED. On my server, the httpd.conf is empty, instead everything (almost) is in a file called apache2.conf. Anyways, I have also read I have to change the AllowOverride None to AllowOverride All in some file... My httpd.conf is empty as you know, but I have a folder called sites-enabled which contains a 000-default file. This is where I have set: AllowOverride All Now my goal as I stated in the last Q is to turn this link: http://mydomain.com/ad.php?ad_id=Bmw_nice_M3_497379462 into this: http://mydomain.com/Bmw_nice_M3_497379462 So as I got an answer in the last Q i inserted this into the htaccess file: Options +FollowSymLinks Options +Indexes RewriteEngine On RewriteCond %{REQUEST_URI} !^/ad\.php RewriteRule ^(.*)$ ad.php?ad_id=$1 [L] Now, this works (no fully) when entering the url manually in the adress bar, but my website isn't working now for some reason. It is like the website is locked down or something, and unless I change AllowOverride to None it will act like that. Any ideas why? Also another note, the links inside the rewritten url doesn't work properly (images are not shown, while some are shown)...
