Aim:
I want to look/log for internal system calls that are being made after i do 'make' command in bash terminal. So that after the make is done, i can look and study the internal method/file calls made while make was happening. In this way i will come to know how the actual building process works.

Ubuntu :: System To Drop Telemarketer Calls?
Aug 6, 2010I've been receiving a ton of calls from telemarketers and political callcenters. What would be the simplest way to use Ubuntu to automatically drop calls incoming from blacklisted numbers?
I have Comcast Digital Voice service, which is technically VOIP but I think it interfaces with modems themselves just like any other phone service would.
I have a dedicated Ubuntu server sitting next to a phone jack already, so I'd like to use that if possible.
I've seen FreePBX and Asterisk, and hear that they can do the job. However, I haven't been able to tell just how easily they could be set up. It sounds like they might require me to get rid of all my phones and use soft phones instead... Does anybody know if it is as simple as buying a voice modem and configuring a PBX software to interface with it?
Ubuntu :: Return Values From System Calls?
Apr 30, 2011I've implemented a few custom system calls in my Ubuntu kernel, but I'm having some issues with the return values. Each function returns a variety of non-negative integers depending on which error is encountered. However, when I'm testing the system calls, the only negative value that gets returned to the user program is -1, regardless of what I have in the code.
Is there some special path I have to take to get the proper return values?
General :: Tracing An User's System Calls?
Mar 27, 2010I would like to trace a user's activity by monitoring system calls. Is there a way to use strace such that at startup it will begin tracing all system calls? Or is there any other method to automatically trace the system calls used during a user's session automatically without having to call strace manually?
View 6 Replies View RelatedGeneral :: Error Checking On System Calls
Sep 19, 2010I'm new to C language and some help finding places in the following code where a system call is made and error checking is not done. I found one but since I don't know C language at all I'm not exactly sure what else to look for. Link to my file: [URL]...
I found one and added error checking:
if (setoutpipe){
//Changes: Added error checking to the system call close()
//Orginal Code: close(pidefd[1]);
if(close(pipefd[1] != 0){
fprintf(stderr, "Could not close piple.
");
exit(255);

Programming :: How To Include Variables In System() Calls
Mar 12, 2010I need to include variables in a system() call. This is that I have:

using namespace std;

P.S.: I know this is a pointless redundant program, but it's part of a larger project learning process.

General :: Log Or Live Data That Discloses The System Calls An Application Makes?
Apr 5, 2011I want a log or live data that discloses the system calls an application makes. I have used strace but can't find a guide for it that is decent. I'm interested in knowing the calls made after user intervention like opening a menu and so on. If you run (strace application_name) it is static. What good is this? When does strace make this file? When is this log produced?

Fedora :: Firefox Does Not Show Up In System Monitor
Apr 18, 2011I recently installed FC14 on my system as I was previously on FC8. Everything seems to be working fine, but I ran into an issue today where I wanted to kill firefox. I checked in gnome system monitor and I did not see a running process for firefox or firefox-bin. I also ran a "ps -e" command from a terminal as root and did not see it there either. I don't know if this is a fedora issue or a firefox issue, so I am posting it here first.
And just to vent on something that IS a firefox issue. I have the new firefox 4 running and when I click the X in the top corner, it doesn't give me the option to save my current tabs and exit like the previous versions did. That was a feature I liked.

Fedora :: Get System To Show Deps For Particular Target?
Aug 11, 2011I read the manual for systemD and systemctl, and I could not see a way to display the dependencies of local-fs.target. My system hangs at boot, somewhere before the local-fs.target completes. Not only do I know know what is failing, I don't know what it is trying to do.I can boot to the emergency target. But that does not trigger the problem. I have the logging options on, but it FREEZES when I try the local-fs.target, so I never get to open the logs. I'd like to know what it is trying to do, so I can step through manually.
I boot to emergency. Manually start each local-fs.target.wants/* then local-fs.target It waits a long tome for something, then it "works" but does not mount my lvm filesystems. I try again for default.target, and this time local-fs.target fails with a dependency, and the system hangs again. syslog is not available at the time of the hang. What ever is the first fail, is lost when the console scrolls.I's looking a lot like I must do a full reinstall of this system.
CentOS 5 Hardware :: System Won't Boot After Recent Updates?
Jul 18, 2009I did a yum update to install quite a few updates to my Centos 5.3 x86_64 system. Updates included kernel and xen which required a reboot. It must be a month or so since I last updated. The updates seemed to go fine - but when the machine restarts it goes through the bios screens which seem to detect all the hard drives etc - but then the word "Grub" appears at the bottom of the bios screen - and the system hangs. It doesn't appear to respond to keyboard input. The system is using linux raid in case that is relevant.
I am able to boot a centos5.2 live CD and look at the Logical volumes - and all appears in order to my untrained eye. I have also mounted the /dev/mdo as /tmp/bootx (boot volume) and had a quick look at /tmp/bootx/grub/grub.conf and /tmp/bootx/grub/device.map and again - I can't spot any obvious problem. I note that before the updates - my default boot was "1" and now it is "0" though this appears reasonable because the xen and non-xen images seem to be listed in the opposite order to earlier updates. I have set it to boot non-xen by default - and this has always worked in the past.
I realise that the recent updates may be a coincidence - and whatever is wrong may have occurred earlier. I cannot think of anything I have done which could have broken grub though. I can probably restore my boot volume to the state it was before the updates. I should have a backup from this morning - as luck would have it. Is this a safe thing to do - or do I need to restore both boot and root to keep them consistent. I would prefer not to restore the root system unless I have to - as this would cause some data loss. However I need advice as to whether yum and other things will get confused if the boot volume is restored in isolation.

Mar 7, 2010Completely new to Ubuntu, basically never used anything but Windows before, hadn't even had a chance to properly test out Ubuntu before I broke it. So, sorry if this question is very easy...or if I'm posting it in the wrong place...
Anyway, I cleverly installed the most recent drivers for my graphics card, and it killed Ubuntu - it won't start now. This happens on Windows, too, but Windows will System Restore for me. How might I fix this in Ubuntu?
I can choose Ubuntu from the grub menu, but then the screen goes blank, the fan on my computer goes into overdrive, and nothing happens.
Am currently running my Karmic Koala from LiveCD...
Software :: Script Calls Another Script Which Calls 'bash' Inside
Mar 15, 2010I need to write a script. In which, the 2nd part commands need to run under another bash shell environment.The enter_antoher_bash_env.sh will setup a new shell environment, call "bash". The rest commands need to run under the new env. (I cannot change this script too. )If I run these command one by one manually, it works of course. If I put them into a script, enter_another_bash_env.sh won't return because it calls "bash" command inside.
