  • How do I determine the linux server software/version and email server software/version running

    - by rwilkins
    I just inherited this a single linux box running pop/smtp for a small office (25 users). I'm new to Linux. I think the box is running Debian GNU/Linux 5.0 as the server (this is bannered accross the screen occassionally) but not sure of the release/kernal/build etc. I need to be certain of both the server os and email linux versions in order to perform research, admin and support. Any help/pointers on how to do this is much appreciated.

  • update-grub is setting a wrong linux root partition

    - by adrian m
    Initially, Ubuntu was installed on another partition (sda5 or sda4). At some point I did manually move the root partition to sda2. Now, the problem is that whenever a new kernel is installed, the automatic regeneration of the menu.lst is using the OLD Linux partition. So I have to manually change in menu.lst the lines : root (hd0,5) into root (hd0,1) How can I configure update-grub to automatically generate menu.lst with the current Linux root partition? I assume that the (hd0,5) was written somewhere at installation, but I couldn't find it.

  • Music Players in Ubuntu/Linux [closed]

    - by v2r
    Music Player, just like Web Browsers are an important part of today's application repertoire, and not only for entertainment reason. Having tried a few Linux Player over the past years i come to wonder, which Players you prefer and what kind of Players are out there, that you suggest are worth looking into and why!! I used Rhythmbox for a long time, but "Jamendo and Magnatune" plugin are both no longer available in 11.10 and also my covers are not shown, since i stream my music folder from a second partition. aTunes is another great Player, but there are also some flaws which i contacted the developers about. It would be nice if you post some alternatives! --Thank you. Example: Name of Player: aTunes | Homepage Additional Info : aTunes is a java-based Music-Player for Linux/Unix/Windows and ... Only one player-example per answer, please!!

  • Global variable in a Linux shared library

    - by user3730495
    Suppose we have the following setup under Linux, .so library named "libcnt.so" and 3 user space apps: "app1", "app2", "app3". This library does 1 simple thing, it says to the app (app dynamically links the library at runtime) by how many apps it is already linked. Apps should have access to link counter. My knowledge in C and Linux is somewhat limited in this aspect, but as I understand this information should be stored in a global variable inside the shared object. Something like: in libcnt.h extern int cnt_loads; in libcnt.c int cnt_loads = 0; // where each linking increments this counter or something... So, my question is how it should be declared and/or defined inside .so library to guaranty that multiple apps from user space get the same instance of that variable counter?

  • Clone a Hard Drive Using an Ubuntu Live CD

    - by Trevor Bekolay
    Whether you’re setting up multiple computers or doing a full backup, cloning hard drives is a common maintenance task. Don’t bother burning a new boot CD or paying for new software – you can do it easily with your Ubuntu Live CD. Not only can you do this with your Ubuntu Live CD, you can do it right out of the box – no additional software needed! The program we’ll use is called dd, and it’s included with pretty much all Linux distributions. dd is a utility used to do low-level copying – rather than working with files, it works directly on the raw data on a storage device. Note: dd gets a bad rap, because like many other Linux utilities, if misused it can be very destructive. If you’re not sure what you’re doing, you can easily wipe out an entire hard drive, in an unrecoverable way. Of course, the flip side of that is that dd is extremely powerful, and can do very complex tasks with little user effort. If you’re careful, and follow these instructions closely, you can clone your hard drive with one command. We’re going to take a small hard drive that we’ve been using and copy it to a new hard drive, which hasn’t been formatted yet. To make sure that we’re working with the right drives, we’ll open up a terminal (Applications > Accessories > Terminal) and enter in the following command sudo fdisk –l We have two small drives, /dev/sda, which has two partitions, and /dev/sdc, which is completely unformatted. We want to copy the data from /dev/sda to /dev/sdc. Note: while you can copy a smaller drive to a larger one, you can’t copy a larger drive to a smaller one with the method described below. Now the fun part: using dd. The invocation we’ll use is: sudo dd if=/dev/sda of=/dev/sdc In this case, we’re telling dd that the input file (“if”) is /dev/sda, and the output file (“of”) is /dev/sdc. If your drives are quite large, this can take some time, but in our case it took just less than a minute. If we do sudo fdisk –l again, we can see that, despite not formatting /dev/sdc at all, it now has the same partitions as /dev/sda.  Additionally, if we mount all of the partitions, we can see that all of the data on /dev/sdc is now the same as on /dev/sda. Note: you may have to restart your computer to be able to mount the newly cloned drive. And that’s it…If you exercise caution and make sure that you’re using the right drives as the input file and output file, dd isn’t anything to be scared of. Unlike other utilities, dd copies absolutely everything from one drive to another – that means that you can even recover files deleted from the original drive in the clone!

  • Suspend not working after kernel update on an HP Envy14 1050

    - by leoxweb
    I just update ubuntu 12.04 to the kernel 3.2.0-30 and together with it a lot of packeges in the system. I am running it on an HP Envy14 1050. When I first made a fresh install of the clean ubuntu 12.04 I had the problem that when restoring from suspend the screen was black, although some backlight was there. I could fix it following this https://bugs.launchpad.net/ubuntu/+source/linux/+bug/989674/comments/20. Now, after the update the black screen after suspend has reappeared but with no backlight at all and the led in the caps lock key blinking. The laptop is using a ATI radeon 5600 with the privative drivers. During the update process there was an error with depmod . You can see the /var/log/dist-upgrade/apt-term.log file at the end. UPDATE: suspend is not working at all. The problem is not when restoring from suspend, but when I try to suspend the system it gets blocked and the fan running. Only option is to press power button.

  • Linux HA / cluster: what are the differences between Pacemaker, Heartbeat, Corosync, wackamole?

    - by Continuation
    Can you help me understand Linux HA? Pacemaker, Heartbeat, Corosync seem to be part of a whole HA stack, but how do they fit together? How does wackamole differ from Pacemaker/Heartbeat/Corosync? I've seen opinions that wackamole is better than Heartbeat because it's peer-based. Is that valid? The last release of wackamole was 2.5 years ago. Is it still being maintained or active? What would you recommend for HA setup for web/application/database servers?

  • How to run infinitely script in background on Linux?

    - by Andrew Bashtannik
    I have a PHP script with infinite loop. I need this script running forever. So, I run php /path/to/script.php > /dev/null & And it works in background in my current user's security context. But when I close terminal window (log off), of course, CentOS Linux kills my program. I see two guesses: run from a different user in background or make a daemon. I need help in each situation. Thanks a lot!

  • REDUX: How to overcome an incompatibility between the ksh on Linux vs. that installed on AIX/Solaris

    - by Andrew Stein
    I have uncovered another problem in the effort that we are making to port several hundreds of ksh scripts from AIX, Solaris and HPUX to Linux. See here for the previous problem. This code: #!/bin/ksh if [ -a k* ]; then echo "Oh yeah!" else echo "No way!" fi exit 0 (when run in a directory with several files whose name starts with k) produces "Oh yeah!" when called with the AT&T ksh variants (ksh88 and ksh93). On the other hand it produces and error message followed by "No way!" on the other ksh variants (pdksh, MKS ksh and bash). Again, my question are: Is there an environment variable that will cause pdksh to behave like ksh93? Failing that: Is there an option on pdksh to get the required behavior?

  • Can I use a serial port as TCP/IP interface on Red Hat Linux?

    - by ShaChris23
    Background We want to run an FTP server on a Red Hat Enterprise OS. The problem is, the machine we have does not have an Ethernet port/interface (please don't ask why; it's just a project requirement). We only have a serial port. Question Is there COTS / open source software that I can use to make serial port "look" like a an Ethernet port? My project is commercial. We run Red Hat Enterprise Linux 5.3. Note: Pardon me if my post title is unclear. If you can think of a better title, please suggest or simply change the title.

  • How do I move a Java JFrame partially off my Linux desktop?

    - by Erick Robertson
    I'm writing a Java application with movable frames, and I've come across a quirk in Linux. I'm running GNOME 2.16.0 under CentOS. When I use JFrame.setBounds to set the bounds to any location that's half off the screen, it actually sets the location of the frame to be as close as possible to the bounds specified while still staying completely on the screen. This is confusing because other non-Java windows can move half off the screen. How do I tell Java to tell GNOME to actually put the frame where I specify, even if that's half off the screen?

  • Why are functions loaded at aligned addresses in x86 Linux for elf executables?

    - by user344787
    Hi, I've been looking at Linux elf executables on x86, mostly using IDA but also gdb. One thing I've noticed is functions are always loaded at word aligned addresses? Anybody knows the reason of that? I am not aware of any requirement of x86 instructions to start at aligned addresses. And it cannot be due to page alignment cause the page boundary can still be anywhere within the function. I would appreciate any insight at all. Thanks.

  • How do I prevent JDialog from showing in gnome-panel(Linux)?

    - by aeter
    I have a class: public class ANote extends JDialog{...} In GNOME(Linux) it shows an entry in the gnome-panel. I want it to show nothing (the same way it does in the taskbar in Windows), because there may be present several instances of the class simultaneously, and this overcrowds the gnome-panel. How do I prevent it from showing an instance in the gnome-panel? EDIT: So far I have tried playing with the modality, which hides it from the gnome-panel, but blocks the main frame of the application behind the ANote instances.

  • How do I send a file as an email attachment using Linux command line?

    - by Kit Roed
    I've created a script that runs every night on my Linux server that uses mysqldump to back up each of my MySQL databases to .sql files and packages them together as a compressed .tar file. The next step I want to accomplish is to send that tar file through email to a remote email server for safekeeping. I've been able to send the raw script in the body an email by piping the backup text file to mailx like so: $ cat mysqldbbackup.sql | mailx [email protected] cat echoes the backup file's text which is piped into the mailx program with the recipient's email address passed as an argument. While this accomplishes what I need, I think it could be one step better, Is there any way, using shell scripts or otherwise, to send the compressed .tar file to an outgoing email message as an attachment? This would beat having to deal with very long email messages which contain header data and often have word-wrapping issues etc.

  • How can a running application in Linux/*nix determine its own absolute path?

    - by Dave Wade-Stein
    Suppose you run the application 'app' by typing 'app', rather than its absolute path. Due to your $PATH variable, what actually runs is /foo/bar/app. From inside app I'd like to determine /foo/bar/app. argv[0] is just 'app', so that doesn't help. I know in Linux I can get do pid = getpid(); and then look at the /proc/pid/exe softlink, but that doesn't work on other *nix. Is there a more portable way to determine the dir in which the app lives?

  • How would I go about writing a Linux TTY sniffer?

    - by alienate
    For educational purposes (not that anyone should care the motivations behind such an exercise) I'd like to write a program that can read/write to/from alternate tty/pty's. I've read papers (from the 1990's) but can't employ the implementation they use, on modern UNIXes. I was hoping that someone had researched into this in the past, or at least, read documentation pertaining to it, that they could provide. I also wonder if (considering the fact that Linux doesn't have STREAMs) if this exercise must be done via a loadable kernel module? I have many questions and probably a misunderstanding of some of the fundamental ideologies that allow such objectives to be put in place, could someone help? :)

  • How can install sqlite-ruby on linux when sqlite3 is not in /usr/local ?

    - by Charles
    I am trying to install sqlite3 and sqlite-ruby (ruby 1.8.6) on a linux box where I do not have root. I downloaded the sqlite3 source, binaries, and shared library and placed them all in a directory called sqlite3 I then try to install sqlite-ruby using gem install sqlite-ruby --with-sqlite-dir=the_path_sqlite/sqlite3 but I keep getting the error... checking for main() in -lsqlite... no checking for sqlite.h... no * extconf.rb failed * Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers. Check the mkmf.log file for more details. You may need configuration options. Provided configuration options: --with-opt-dir --without-opt-dir --with-opt-include --without-opt-include=${opt-dir}/include --with-opt-lib --without-opt-lib=${opt-dir}/lib --with-make-prog --without-make-prog --srcdir=. --curdir --ruby=/data/scratch/bettbra/common/packages/ruby-1.8.6/bin/ruby --with-sqlite-dir --with-sqlite-include --without-sqlite-include=${sqlite-dir}/include --with-sqlite-lib --without-sqlite-lib=${sqlite-dir}/lib --with-sqlitelib --without-sqlitelib

  • Which is the best Linux C/C++ debugger (or front-end to gdb) to help teaching programming?

    - by omer.gimenez
    I teach a sort of "lite" C++ programming course to novices ("lite" meaning no pointers, no classes, just plain old C, plus references and STL string and vectors). Students have no previous experience in programming, so I believe that using an interactive debugger would help them understand program flow, variables, and recursion. The course is taught in Linux. Teaching them to use gdb is just overkill (they will not use nor understand most features). I just need something simple but easy to use: to see at which line the program is now, what is in the stack (local variables, previous calls, etc.). I look something similar to old Turbo Pascal or Turbo C++ Borland's debugger, or Visual Studio debugger. Thank you,

  • How to tell if running in a linux console versus an ssh session?

    - by Stéphane
    I have an application that needs to behave differently if run directly from the linux console. So if a user connects with SSH to run FooBar, or the user walks over to the console and logs in directly to run FooBar, I want it to do something different. What C API do I need to call to tell the difference between these two scenarios? I was thinking I'd have to look at the "tty/pts" information (such as what I see when I run "ps axf"), but I'm not certain if that is the best solution, nor what API to call to get that information. Hints appreciated. :)
