running Linux release 2.4.19-uc0, build #511 embedded on a device. It is stripped down to a very minimal configuration and so many of the normal commands are not present.I'm trying to force a reboot from an application I've got running. I've tried the following:
system("shutdown -r");
or
sync();
[code]....
I know I can force a fsck run at next reboot using
Code:
shutdown -rF now
or
Code:
touch /forcefsck
can I force the fsck to more indepth checks such as doing directory optimisations, bad blocks checks, etc. maybe by passing parameters to the fsck call during startup?
todays update required a restart an then it went into check disc mode but i dont have time to wait and ended it.is there a way to force a check disc on a reboot when i do have time?

View 2 Replies View RelatedTwo or three times on a daily basis it just freezes and I do not know why. For example, I am doing some minor coding, surfing the web and just some regular stuff and suddenly, out of nowhere, it just freezes. I cannot force reboot, cannot shutdown, cannot run, cannot enter terminal, nothing. Totally helpless. Only physical reboot do the work. Never had this issue before.

I can get a virtual console by banging on the fn ctrl option f2 keys I can then use 'startx' to get another black screen but clicking around for a bit gives me the gnome fallback windowing. Is there any way I can force the gnome fallback to start up directly on a reboot?

At the moment im using a live linux distribution and running a program to test the security of my website. Unfortunatly this program is running from, and seems to fill up rootfs, at which point the program crashes and dissapears.
Is there any way to force a program to run totally from RAM, which i would presume would automatically use a swap file because of the in built memory management in linux, of which is a 30GB partiton.
I know i could just install the distribution to the partition instead, however it has peaqued my interest in just how much control linux has over the programs running on it.
So the question is - Is it possible to run a program totally from RAM, forcing all inputs/outputs to be re-directed to/from RAM to keep the rootfs clear whilst the application does what it needs to?
I decided I was going to compile XChat from source today for "fun." What I ended up doing was spending a few hours getting it to compile, then find out everything didn't work the way I thought it did. I was under the impression that after I ran "sudo make install" I was "upgrading", when in reality I'm just installing a seperate version alongside the old one. Apparently I have to keep the old version so every program that was compiled with it will continue to work, so how do I:
1) Force a program to use a specific version of GTK when compiling.
2) Find where my version of GTK installed to.
I've asked some people and I've just been told to "learn LD_PRELOAD". I've googled and can't figure how I could even apply that to my current problem
what the shortcut keys are to force quit a program that has frozen up in Ubuntu 10.04? I use to know it, but can't remember
View 4 Replies View RelatedI have added to my Panel the "Force Quit" program to click and use so I don't have to type it in on the rare occasions that I need it. I accidentally clicked it today not needing it. Not knowing this would be an issue, I clicked on it thinking it would force itself to quit and just close itself. I know I should have just hit esc to close it.
The problem I have now is that it is now frozen on my screen and for the life of me I cant figure out how to get rid of it. Yes I tried esc. I tried opening System Monitor and looking for it to end the prog and couldn't find it. I know I could fix this by just restarting the x server, but at the moment I happen to have several things open that I either cannot save right now or are actively running.

View 1 Replies View RelatedI sshed into a Linux machine (bash shell) from a public Windows machine (in our lab) and forgot to log out. I'm now back at my seat in another room and I am too lazy to walk back and log out that session; I can ssh into the Linux machine from my current PC though. Can I force-logout the other session from a new SSH session?
When I ssh to the Linux box from my current PC and type users command, I can see that I'm still logged in there; my name is listed twice - one for the current session and another for the session from lab PC.
I don't have root privileges on the said machine, but I guess that shouldn't matter as I'm just trying to log out myself.
I'm trying to upgrade to Firefox 5 on RHEL5, and am getting the following error:
./firefox-bin: /usr/lib/libstdc++.so.6: version `GLIBCXX_3.4.9' not found (required by /home/isdtc/tdiakiw/bin/firefox5/firefox/libxul.so)
As the computer is a work machine,I don't have access to update the libraries directly. To try and get around this I downloaded the libstdc++.so.6.0.10 library.strings libstdc++.so.6.0.10 | grep GLIBCXX shows:

I created a group, and after adding the users into this group, they have a /home/worksharing that is shared
Code:

For personal reasons (I'm hearing impaired) I need my linux machine to produce mono downmixed sound. Downmixed, not just single channel.
Is there any possibility to force such behavior in ALSA / PulseAudio server? Hardware mixing (short-circuiting L and R channels with some resistors) is not possible at the moment. I'm looking for a software solution to mix two channels into one.
I know that some media players have this functionality, but I'd like the whole system (ie games, flash applications, etc) to produce downmixed audio.
I am running a series of tests for an implementation of a remote pager that sends page faults to other computers in a network. Long story short, I was wondering if there is an easy way to force a process to use virtual memory as oppose to physical RAM so that I can better measure the performance of my implementation against how the system would perform while swapping to the hard drive.

Is there a way to instruct mencoder to stop streaming/recording after a specified period associated with a loss of signal?I use mencoder to record over-the-air television recordings. Most of the time there are no problems.Occasionally a station's transmission signal disappears, caused by quirky atmospheric conditions, usually at night.Noticing these signal outages is easy by the mencoder error message:dvb_streaming_read, attempt N. %x failed with errno %y when reading %z bytes"Lengthy outages are unbearable because mencoder silently waits forever rather than quit.
The significant problem with lengthy signal outages is mencoder continues recording for the time specified by the -endpos parameter. Thus, for example, if the recording is scheduled for 2 hours and there is a 20 minute loss of signal, the recording does not end until 2 hours and 20 minutes after starting.Generally, when the interruption is lengthy the recording is ruined and I don't care to watch. I would like to programmatically tell mencoder to stop waiting and quit.Is there a way to do this? Say, after ten minutes of no signal, just terminate do not notice any parameters that might offer that option, but I could be overlooking something obvious. I tried the -skiplimit parameter with no success.

View 4 Replies View RelatedI've hired a dedicated Ubuntu10.10 Server on a remote colocation. I needed a GUI to be able to hook into my KVM guests, so I installed xubuntu-desktop.
My dedicated server provider provides me very useful free service. I can request a CTRL+ALT+DEL to my server through their web based server control panel, and I can boot into a live image from their network. This is vital for me to be able fix back configuration problems.
However after I have installed xubuntu-desktop (XFCE I believe), the CTRL+ALT+DEL no longer reboots the machine.
I've been struggling with this simple issue for quite a few days, I simply can't get it to work.
I've tried setting it through XCFE 4 Settings Manager. It does not work. From my understanding any keyboard shortcuts defined here are specific to user, so I think they'll not work when the server is in login screen (no user logged in).
I've tried to put control-alt-delete.conf files in /etc/init and /etc/event.d/ , neither seems to trigger reboot. Documentary propose /etc/event.d has been deprecated since Ubuntu9.04, i tried it anyways.
Content of the file is
# control-alt-delete - emergency keypress handling
#
# This task is run whenever the Control-Alt-Delete key combination is
# pressed, and performs a safe reboot of the machine.
