i just want to know whether we can execute the commands in invisible mode in linux. i.e.the command we typed must be executed but should not be visible.is it possible.
if not,then how the password we are typing is not visible in linux,while creating or entering password for users.
I have a USB modem on a Debian install that I want to be able to use AT commands to diagnose, specifically for obtaining signal strength (RSSI). I know the command for this is AT+CSQ but I cannot seem to get the interface for issuing AT commands to work.
The modem is using /dev/ttyACM0 and when I try to use minicom, I type in AT commands and nothing is echoed to the screen (Yes, echo is turned on). Maybe I just don't know how to use minicom correctly.
For routine tasks i have to execute commands on machines running both winxp and linux. I usually do it via telnet. But the process is very manual as i have to authenticate for each machine then specify the command.
Is there any way that i could automate this job using a script or so?
I have setup lirc on my htpc and it works perfectly, but I am trying to use irexec to execute commands from my remote controller, and this does not work.
Basically, I loosely based my setup on this thread at the XBMC forums (starting at step 3 because lirc is configured and runs the Slackware way !): [URL]
The thread on XBMC's forum uses irexec and irxevent to execute commands. I am not 100% sure why irxevent is used but I am interested to know why and what it really does...
In the meantime my .lircrc file looks like:
Code:
# Start XBMC
begin
remote = harmony2
prog = irexec
[Code]....
but irxevent wouldnt start normally. My understanding is that irxevent uses the display of the parent owner (in my case root since it is called from rc.local) so I tried to start it as normal user and it worked.
So on top of my problem executing commands with irexec, I would like to know how to execute a process as a different user so I can have irxevent started as a normal user by the system at boot time?
I need to hide all the contents in a file sytem. Any command is there or need to tune the kernal parameter...

View 11 Replies View RelatedI was having an annoying problem with icons on my KDE desktop moving out of place, even if the icons were locked. I blamed KDE, but I don't have the knowledge or experience to guess what part of KDE was the problem, so I reinstalled most or all of KDE. That did indeed solve the problem, but it caused two minor new "problems." Both I can ignore, but one I should probably fix. One, the MEPIS splash screen was replaced by a Debian splash screen. Two, on the session menu, root became invisible so I can no longer select it with the mouse; I can only type it in (which I don't mind doing).

My linux workstation recently crashed. After rebooting, Linux (Red Hat 5.3) will not boot properly and automatically went into emergency mode or recovery mode i think. I can still see my /home/user/ and all the files inside.I boot from CD to rescue mode and tried mounting read-only the /dev/sd5 which contains the files in the crashed hard disk to try to copy out my files but mounting was unsuccessful (invalid argument). I checked the filesystem type using fsck -N /dev/sda5 and shows it to ext2. i tried to mount another known working hdd and was successful.
My question is why in emergency mode, the crashed hdd is able to be mounted automatically as read-only but cannot be done in rescue mode thru a bootable CD?Is there any special mount options used in emergency mode?I also cannot copy out in emergency mode booting from the crashed hard disk as everything is read only.

I have a some c source code files that i have to copy to linux machine from a windows machine over a network. This source code folder has to be copied into a particular directory structure in the linux system at the other end. After copying the file into the appropriate folder in the linux server i have to instruct the linux machine to make(using the make file that is there with the c files) this source code from the windows machine. Does anyone have any idea in regard to how this can be implemented?? i am trying to have a gui client that has the above mentioned options(copying and inserting the c files into the appropriate directory and then for making the files and getting the executable.)

I am running Yellow Dog Linux release 6.2(Pyxis) on my PS3. I would like to compile and run C programs that utilize OpenMP for parallel programming. Unfortunately, I have not been very successful. I am able to compile programs containing OpenMP statements error free, but when I attempt to execute the binaries I receive the following error: Code: ./file: error while loading shared libraries: libgomp.so.1: cannot open shared object file: No such file or directory Compiling programs without OpenMP statements works fine.
Because it has to do something with missing libraries, I am not sure if knowing the executable search paths may help in diagnosis, but when echoing the path environment variable:

The version of GCC on this machine, 4.1.2 20080704 (Red Hat 4.1.2-44), is identical to the ones I have on two other machines (CentOS release 5.3 (Final) and CentOS release 5.4 (Final)) and they both compile and execute OpenMP code flawlessly. I have tried building and installing another version of GCC that would possibly include the OpenMP libraries, since, according to some sources, GCC has only supported OpenMP since version 4.2. But I have not been successful with that either (that problem would make a good second thread.)
