I want to enable a function which is called clone mac...see in the picture. while, some systems don't support such a function... such as centos, the picture was taken in ubuntu 11.04... so, if i want to enable the function in centos or some other distributions which doesn't support this originally, what should i do? is upgrading the network manager functional?
View 4 RepliesI'm using Ubuntu desktop 10.10 on an Hp Pavilion dv2700 laptop. Most of the time I have had no issues, however on two separate occasions the wifi and bluetooth have been disabled, the switch on the front of the computer has no effect.the enable wireless function is grayed out, so I was not able to enable it. The first time it happened, (I didn't have an Ethernet cord at the time), I booted into windows Vista, thinking I could connect to the internet and find an answer. Low and behold I had the same problem in windows, however I was able to enable the wifi and blue tooth in windows. Now, rebooting into Ubuntu, the problem was resolved. The second time around the same thing happened, and I booted into Windows to fix the problem. I have done a search for known bugs on this issue, but none seem to relate to my exact problem. Is there a way to enable the wifi when it is grayed out? like in windows?Like I said this has only happened twice, but I had to boot into windows to fix the problem. I really want to delete windows all together, but if I have to keep it around awhile to fix this issue I guess I will.

Code:
#!/bin/bash
logErrors(){exec 2>/tmp/errorlogfifowhile truedocat /tmp/errorlogfifo |echo $(date "+[%Y-%m-%d %H:%m:%S]") Error: >/var/log/error.logdone}
logErrors
ls inexistentFile
exit 0
If I execute the script I see the formated error message in /var/log/error.log, as to be expected. After the script execution, I hoped "logErrors" was not executing anymore, but when, in another terminal, I call "echo something > /tmp/errorlogfifo", I still see the formated error message "something" in "/var/log/error.log". How can I finalize "logErrors" before the script ends? Or, maybe someone knows a better way to format and log the erros in a script.
I forgot to say that the file "/tmp/errorlogfifo" is a named pipe created by the command "mkfifo /tmp/errorlogfifo".
I have our own C written program code which is communicating with a third party C++ written program code to run a moving device. We have successfully communicated with the third party code with wrapper functions. (Thanks to member in LQ that helped me solved this.)Now, we tried to run some functions to move the device. I think it is better for me to attach the related code first. pro.c (The source code we used to run the device)
Code:
#include<stdio.h>

I am using Debian linux. I have 100 timers running. If a timer expired which will generate a signal and it was mapped to a same function handler. All the timers are mapped to one function handler. The problem is if the timer expires one at a time, the function handler called at a time. But if the 2 timers expires at a time, the function handler is called one time only instead 2 times. Is it possible to invoke the function handler as many times based on timer expirary happens simultaneoulsy?

I got a new laptop Toshiba L526. Now I want to make it's Function keys work. I have read many threads, and found it is better using acpi.
But when I try
modprobe toshiba_acpi
it got a error :
FATAL:Error inserting toshiba_acpi(/lib/modules/2.6.29.6-smp/kernel/drivers/platform/x86/toshiba_acpi.ko): No such device.
My slackware version has upgrade to current exclude the kernel packages and alsa. The kernel I use is 2.6.29.6-smp. When I run acpi_listen,no output.
I feel there's a bit of a misunderstanding going on between C++ and me...My problem is that I have a deque of pointers to a class, and create objects then add them to the deque in a for loop. However, the destructor is called on the object as soon as the loop quits.
Code:
This prints:
Code:
Now, if I change the deque from deque<Test*> to deque<Test> then it works fine - I get:
Code:
However, I can't do this with my actual code, because I am creating a deque of pointers to an abstract class, so it won't let me instantiate the class. (This is all so that I can take advantage of polymorphism, and call functions on a set of similar objects without worrying what type of object I'm dealing with).
So, I suppose my question is: what is the correct way to create that deque of pointers to the abstract class? I don't seem to be barking up the right tree currently.
i am trying to use a small application called toonel. its in jar format and it helps to compress traffic. i can run it succesfully but i cant seem to be able to get my applications e.g firefox to communicate with it!
normally in windows i just start the app, then set my browser proxy to 127.0.0.1:8080 which is where it listens for connections but so far in ubuntu i cant seem to be able to get it to work.
Bit of a strange one, to get internet I have to clone my MAC address on eth0. I'm using Ubuntu 10.10 64bit and have had a couple of strange problems.
1. If I run macchanger after login and set the mac to the correct one everything works perfectly. But as soon as I reboot it reverts back to the old mac.
2. If I use the network settings (i.e., the tray icon in the top right) to spoof the mac, then I get no connection. Eventually it does connect (I'm talking about a 10 minute wait) then I get kicked off after a few minutes.
3. If I edit the /etc/network/interfaces files there is no setting for et0. All that is in the file is:
auto lo
iface lo inet loopback
If I add the settings for et0 then I get the same problems as in 2. The settings I've been adding are.
auto eth0
iface eth0 inet dhcp
hwaddress ether 01:02:03:04:05:06 (obviously with a different MAC)
git clone is very very slow..This internet is capable of 630 kb/s and git is only cloning it at 30kb/s-80kb/s from git://kernel.ubuntu.com/ubuntu/ubuntu-natty.git and I am trying to make a custom kernel. I am the IT for my company. And I am trying to make a new kernel for our linux server. I am still somewhat new to Linux, but I know for a fact over the several T1's we have fused it shouldn't be this slow.

View 3 Replies View RelatedI run a VMware clone of CentOS 5.3, I observe that kudzu [i.e. /etc/init.d/kudzu, from /etc/rc3.d/S05kudzu or /etc/rc5.d/S05kudzu] detects a MAC address change on eth0 and then creates a /etc/sysconfig/network-scripts/ifcfg-eth0.bak file. This .bak file is identical to the original ifcfg-eth0 file except for the value of the HWADDR [i.e. MAC address] parameter. I would be unconcerned but for the fact that /usr/bin/neat indicates that both ifcfg-eth0 AND ifcfg-eth0.bak are 'Active'. The following solution may help others with the same (or similar) problem:

I am doing some Linux kernel programming for my research project. I need to record the timestamp (by using cpuid and rdtsc) when an interrupt handler (top half) is first invoked. Due to the time critical nature of the problem itself, I have to do the timestamping inside the interrupt handler itself (the first operation when the handler is called). However, I understand that tasks that are not so time critical should be deferred to a tasklet function (bottom half) for processing because other interrupts are disabled in a (top-half) interrupt handler. I am currently out of idea on how I can pass the timestamp information that I have obtained in the interrupt handler to the corresponding tasklet function.
View 2 Replies View RelatedI'm currently using OpenSuse 11.1 web server. This is bad since 11.1 is no longer supported. the reason why I am using it is because Function set_magic_quotes_runtime() was no longer being used. (so I was told)
That being said, is there a way to get Function set_magic_quotes_runtime() to function on the newer versions of OpenSuSE?
the function terminates if no key is pressed for 10 consecutive seconds. I tried using the -t option as suggested in some forums, but my version of showkey doesn't have the option of changing the timeout. The options I get are:
-h --helpdisplay this help text
-a --asciidisplay the decimal/octal/hex values of the keys
-s --scancodesdisplay only the raw scan-codes
-k --keycodesdisplay only the interpreted keycodes (default).
Is it possible to write a script to use this function and still keep the function active until an interrupt is recieved?
Here are the specs of my machine: Linux matrix 2.6.18-92.el5 #1 SMP Tue Apr 29 13:16:12 EDT 2008 i686 i686 i386 GNU/Linux Red Hat Enterprise Linux Server release 5.2 (Tikanga)
When I run an ldapsearch in root, it works fine. tcpdump filtered by dest IP shows packets captured.
When I run an ldapsearch in a perl script as root, it works fine. tcpdump filtered by dest IP shows packets captured.
However, when I run it via a perl script in my cgi-bin directory it fails. tcpdump shows no packets captured. When I added a "2>&1" to my ldap search in my cgi script, I got "ldap_bind: Can't contact LDAP server (-1)".
I ran a "whoami" in my cgi script and it showed up as apache.
Another twist to all this is that I ran the same test on my slackware box, and everything works (esp the cgi script). Here's what the specs are on that machine:
Linux slackvm 2.6.29.6-smp #2 SMP Mon Aug 17 00:52:54 CDT 2009 i686 Intel(R) Core(TM)2 Duo CPU P8400 @ 2.26GHz GenuineIntel GNU/Linux
I checked the permissions on the ldapsearch file and directory, and they're the same (755).
Could there be something blocking the apache user on my Red Hat box from sending packets out?
I want to know the basic function of TCP Backlog queue.
View 3 Replies View RelatedHow do I get internet connection through mobile broadband (internet stick Nokia CS 15) for my laptop (Fujitsu Siemens) with encrypted hard disc (LVM)? I have set up LVM using Ubuntu 10.04 Alternate install.
Earlier when I installed the ordinary desktop version (Ubuntu 10.04 desktop) using no encrypted disc the internet connection worked fine. Before I installed the software from the internet stick an image appeared (Nokia Modem) on the desktop. I dubbel clicked the image and through the files that appeared I installed the software. After that I clicked the Eject Volume and after some input I had my connection.
But now I dont get that image on my desktop when the stick is plugged in. I can imagine that I have to mount the stick some how. I can further imagine that the encrypted hard disc through its protection now stop me from this action.
I looked on the net for such function or example and didin't find anything, thus after having made one i guess it would be legitimate to drop it to see what others thinks of it.

i'm using ASUS K40IE laptop, installed Ubuntu 10.10 and online upgraded to 11.04 (natty), and i have a problem about my wifi.This laptop using Fn+F2 to enable/disable wifi (using Windows work properly with driver from asus) and have a Led that trigger on/off.Using ubuntu, that's shortcut it's useless. i press Fn+F2 many times, but that led indicator never turn off. Is there a way to make that shortcut can function properly? Actually, i'm not often using wifi, so i want to make it default disable on start up. Both ubuntu 10.10 or 11.04 can't using this shortcut.
View 1 Replies View RelatedWhenever I start up my laptop i do not get a wireless connection automatically. I have to rightclick network manager applet and select enable networking. After that everything works fine untill i shutdown and restart my laptop. I would like a way to change this so that my wifi connection is working whithout having to click something first..
OS:Xubuntu 10.04 LTS!

I just upgraded to natty last night, and everything is working fine except for the network manager. I can enable and configure the wireless card via bash, but the network manager widget will not manage the wireless card.
When I first boot up, the "Enable wireless" check box is greyed out. After I enable the card via the terminal, the "Enable wireless" check box becomes ungreyed, but every time I click it, it instantly unchecks itself. I feel like Currly from the Three Stoogies. Check, uncheck, Check, uncheck.. "Slaps face repeatedly."
I had the elrepo kmod-r8168 driver running smooth for a while on my development box.
Yesterday, I did a clean install on it and when I tried to install the latest kmod-r8168 rpm, it failed to enable the networking support:
# yum --enablerepo=elrepo install kmod-r8168
The install performed all proper steps to disable the 8169 driver, I double checked to be sure.This is not a connectivity issue. If I remove the kmod-r8168 rpm, reboot the server and run the ifconfig eth0 up to activate the interface, everything works as expected. I use the latest kernel (2.6.18-194.26.1.el5 x86_64).
First, I performed a clean install, activated the eth0 and did a yum update, then installed the kmod-r8168 with yum. Then, I reinstalled the OS again, activated the eth0 and installed the kmod-r8168 on a 5.5 CD based kernel, same fail results. The only hiccup is: every time I start the box, I have to activate the eth0 interface (with default CentOS 8169 driver):
# ifconfig eth0 192.168.1.3
# ping -c 3 192.168.1.1 (no packets lost)
# ifconfig eth0 up
Once I do this, I have network connectivity.
I've been experiencing a problem with Fedora in which when I enable Wireless in Fedora, Wireless networking does not work in windows. HOwever, when disabled, it works correctly. Windows claims it is "not able to find any networks to connect to"
EDIT: It seems that when wireless is disabled manually on fedora before shutdown, there are no problems in windows.
My wireless can connect to my router without a problem, but in order to do so (after boot) I must first disable networking in the Notification Area and then re-enable it. I don't mind it too much, but when other people use my computer, it's made painfully obvious to me, that this was never an issue with Windows 7 (as much as I despise MS).
