i upgraded to 10.04 and when i connect my psp system it calls it 9"e instead of PSP wich it used to in 9.04. how to rename it?
View 2 RepliesWhat is the real difference between system calls and normal function calls. Ultimately function calls too would be passed to kernel for some or the other work.

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?
I'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?
I 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 RelatedI'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);
}
I need to include variables in a system() call. This is that I have:
[code]#include <iostream>
#include <stdio.h>
#include <stdlib.h>
using namespace std;
[Code]....
P.S.: I know this is a pointless redundant program, but it's part of a larger project learning process.
what is the command to show the recent system calls in the OS?
View 2 Replies View RelatedI know there is a way to call winapi in runtime in windows. I want to ask how can I call a system call in gcc in runtime (when I don't know what it can be)? I don't mean syscall that I think is for calling only system calls and not library functions.
View 4 Replies View RelatedI'm trying to produce a alphabetic, non-repetitive list of all System service calls in all c files located in a folder. Here's what I got so far.
grep -ow '[A-Za-z]*SYS[$][A-Za-z]*' *.c | sort
Which produces all system service calls in alphabetic order I just need to find out how to make it non-repetitive.
I am working with fedora 6 , i386 architecture.I am trying to write on keyboard port via program.On inspation i come to know that 0x0060 to 0xz006f are used for keyboard in linux 2.6 kernel in the i/o space from kernel.

I 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?
View 4 Replies View RelatedI've a issue on Skype 2.1 beta, my Ubuntu version is Karmic Koala. Well, my camera works perfectly in guvcview and in skype test (I already modified config.xml in my user dir to have 640x480, my cam is Ricoh r5870). OK, as soon as I start my video or I get itautomatically started it goes 320x240 and very bad. I turn it off during the call and I restart it: it works perfectly. Could I solve this issue by telling skype to open the video "just like if it were the second time" ?
View 1 Replies View RelatedI'm running 10.04 on a Fujitsu Siemens Amilo Pi 1505 laptop. Normally, when I plug my headphones in, all sound is diverted to them. I haven't found anything in sound preferences that changes this.(Under Sound Preferences, Output tab, there's a dropdown called Connector.It has options: "Analog Heaphones", "Analog Output" and "Analog Speakers" but they don't seem to make a difference.) I'd like to leave my headphones plugged in all day and setup my machine to play all sounds through my speakers (including Skype ringing), except Skype calls, which should play through my headphones. Skype has a feature to split the ringing and call sounds, i.e. play them on different devices, but the only option in each dropdown is "PulseAudio Server (local)".
View 1 Replies View RelatedI 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.

Just installed Ubuntu 10.04 LTS netbook edition and everything goes well except for one thing.
When I connect my lcd monitor to the vga port the system lags. If I listen to music and browse web pages at the same time, the sound skip and when the page stop loading, music is ok. Also, the mouse skip. If I do circle with it on the desktop without doing anything else, it will skip.
The strange thing if I remove the external monitor and reboot the system everything comes back to normal.
I had Intrepid Ibex for 2 years without any problems. I remember a post saying that powernowd should be disable, but can't find the process from the startup list anymore.
I've been trying for a few hours to connect to the internet on my debian jessie system. I used the netinstall without installing a DE so I boot into the command line for the mean time.
I have had no luck connecting to the internet after trying to configure the network. I have followed the debian tutorial from the wiki and tried some youtube video tutorials. I just have an ethernet cable connected to my home network. I have tried both dhcp and a manual static setup using /etc/network/interfaces and checked the /etc/resolv.conf file. Ping doesn't work and i cant update or install anything on the system...
Not the best idea to dive into the Linux world on my first ever HTPC build. Anyway, here I am. I am trying to connect my computer with a fresh copy of Ubuntu 10.04 to an older CRT TV. My video card has (2) DVI ports as well as an S-Audio port. The TV has S-Audio and the white-yellow-red RCA's. I bought an S-Audio cable today but I cannot get the "detect monitor" option in system>preferences>monitor to detect anything other than the actual monitor I also have hooked up at the moment. I haven't even begun to focus on audio yet, but I expect that to be much smoother than the video side of it.
PC specs just in case:
Gigabyte P35-DS3L
Intel E8400
Generic (2) 2GB RAM
XFX 8800gts Alpha Dog
Razer Barracuda AC-1
WD 500GB
I'm used to LimeWire. Very straightforward. gtk-gnutella has all these frames, windows, etc. Anyways, it's not connecting. Nicotine connects fine, but people say gtk-gnutella is better, as it has access to more.

View 1 Replies View RelatedI recently installed XBMC and Boxee on my Linux laptop, but neither of them are connecting to the internet. Since I'd like to try XBMC first, I'll talk about that here. When I run the program, I do not have a Live TV icon or link on the side. I can see my Music, Programs, Settings, Pictures, Video and Weather links on the sidebar, but my Weather page is blank as in I do not see any weather forecasts or whatever else ought to be on that page. I thought that maybe since I was running XBMC as a user there might be some permissions issues, so I ran "sudo xbmc" and received an error message "Do_Wait: DRMWaitBlank returned -1, IRQs Don't Seem to be working correctly. Try adjusting the vBlank_mode configuration parameter." No idea what that means. I've tried connecting both via Ethernet and my WiFi.

View 1 Replies View RelatedJust upgraded to Lucid (32bit), pulse generally seems to work ok: I get sound out, I can see various apps connecting via the Sound Preferences dialog (audacious, flash via alsa interface, etc.), and my mic seems to work fine too.
However, when starting skype (v2.1.0.81 which defaults to pulseaudio if it's running), it isn't able to output any sound and I never see a connection appear in Sound Preferences. Don't really want to force it to use Alsa or anything like that; I'd be fine with pulse if it would just work.
I've tried installing the .deb from the skype site as well as the official ubuntu package, with the same result. Any idea why pulse seems to be working, but skype can't seem to use it properly?
I'm trying to get audio from a keyboard into my computer. I have a 1/8' to 1/4' adapter, and I can hear the sound from the other end when I connect my earphones to the keyboard, but if I connect it to my computer's microphone port, it doesn't even recognize something connected there. Sound preferences tell me that there are two microphones connected (two built-in microphones), and so does Jack.How do I get it to detect the keyboard? I'm using Ubuntu 9.10 64-bit, if that's of any relevance.
[edit] I also tried connecting this computer to another computer (i.e. Speakers are connected to computer 2, a 1/8' cable goes from the speaker's earphone socket and into computer 1's microphone in). I expected the sound produced by computer 2 to go to computer 1 like regular microphone input would, but it still didn't detect anything and persisted in telling me that there are only two sound inputs on the computer.

The latest version of Spotify incorporates a social networking part, which allows you to connect with your friends to share playlists etc. However, accessing this feature using Ubuntu and running Spotify with Wine isn't the easiest thing to do. Regular Spotify works well, but I cannot login to my Facebook account. Apparantly, this is due to that part of Spotify using IE7 components.
I couldn't get past the diaglogue box asking me to enter usr/pass, but after some googling I got IE7 support for Wine running using Winetricks. Now I can log in, but I get stuck at another point: the window where I'm to accept that Spotify accesses my private information. I click OK but then it just stands still, loading, and nothing happens. I know the new version just came out, how to fix it? Perhaps adding some other stuff with Winetricks beside IE7 support?
I just installed Ubuntu 9.10 and its great. However when I connect to the internet at home it shows that the connection has been established but I still cant connect to the internet. My flatmates are all able to connect. However, I am able to connect from work both wirelessly and through an ethernet cable.
