View 1 RepliesI started a command, it needs very much time. and i have to save the (error-)output. but i forgot it.
is there a way to save the output of a running process? because the process runs over this night and i want to know what did the process do.
I'm trying to run LKL (Linux Keyboard Logger) in a Ubuntu 9.04 VirtualBox VM (VirtualBox 2.2.2 running on a XP host). The package installs fine, but when I try to run it lkl -l -k /usr/share/lkl/keymaps/us_km -o ./kbd.log & it hogs the CPU usage to 50% and never logs a keystroke (in fact the kbd.log file is never created)
View 1 Replies View RelatedThere is text based game in the Ubuntu repos called gomoku (just 5 in a row) it comes with the package bsdgames. The manual page [URL] lists an option (-b) to run it in the background. I want to try that and if I know how it works create a simple graphical front-end. When I start the program with:
Code:
gomoku -b
it starts and remains active, the terminal does not return to prompt which is OK as the command is not finished. The manual says the program reads from stdin, and this might sound stupid but how to get anything there?
I've tried to pipe an echo command to gomoku which works but ends the program after is receives input.
Code:
echo "black" | gomoku -b
just finishes. After that when you type another command like:
Code:
echo "justsometext" | gomoku -b
gomoku tells it expects either black or white as input. So it forgot the previous "black" because it is a new instance.
How do I pass text to an already running gomoku?
I'm trying to remotely run a script on a target machine though the ssh command-line using passwordless login. I know the keys are set up correctly because if I remove the call to the script, the ssh session succeeds and I can log into the remote machine, but when I call the csh script, I don't get any output on the command line. If I call an identical bash script, I do get the output. Specifically, calling line 1 below just returns me to the command line, but running line 2 echo's hello then returns to the command line (both scripts simply contain a single line to echo hello, and both work when run locally on the remote machine). Why do my csh scripts send any output through the ssh link whereas the bash does?
Code:
1) ssh -i /root/.ssh/id_rsa user@remotemachine /tmp/test.csh
2) ssh -i /root/.ssh/id_rsa user@remotemachine /tmp/test.bash Update: I have further determined that nothing I add to the csh gets run either. I've tried touching files and making directories in the scripts, and all gets run using the bash script, but calling the csh script like line 1 above does nothing, nothing is touched or created.
This could be easy but I obviously don't find the way myself, so I'm asking.I have esd running on a small device (router running OpenWRT).This has a large harddrive and a soundcard attached via USB and I'm using it to play my music via mpd, which also runs on this little device.Can't use pulseaudio, which would be better I suppose, because pulseaudio is not available for OpenWRT latest, so it's got to be esd.Playing the sound of movies I watch on my laptop through this device also works.I use mplayer and its esd-output - works nicely.
What I miss and want to do is:direct all sound from my laptop to esd on the above device.Specifically I would like to hear the sound of flash clips like those on ..... or metacafe through the nice speakers attaced to the device rather than through my laptops really low quality speakers.What I've done to get mplayer to output the movies sound through esd is:I just set the ESPEAKER environment variable to the IP of the router - and run mplayer with -ao esd.I also set the default audiosink to be esdsink - but this appearently has not the desired effect.Would I need to have esd running on my laptop?
I cant seem to get the sound working and when I click on perference then sounds and go to the output selection it has only dummy output as a option.

So here's the situation. He plugs his audio jack into his computer and then into the speakers but it still plays from the computer speakers.
I finally got audio working on my ubuntu 9.10 desktop... now I am having sound issues watching movies from a network share.The sound device continually randomly changes to "dummy output device" and then there is no sound output. The sound icon dissapears on the toolbar. To get it back and audio to start working I have to $sudo alsa force-reloadIt seems to happen everytime there is a network delay, the movie will stop for a second and then when it plays the sound is gone

View 6 Replies View RelatedI'm still trying to find out if my coby mp3 player will actually play mtv video files as is advertised.
ffmpeg -formats does list mtv but the only command I really ever used was one to convert a vid to an mp3 so I tried Code: ffmpeg -i test.mp4 -acodec copy output.mtv it returns Code: Unable to find a suitable output format for 'output.mtv' I can't find any mtv files online for purchase or free for that matter, so I know this is all pretty obscure but shouldn't there be a way to convert them since ffmpeg lists mtv format?
After "yum install emacs" & "yum install emacs-ess", I was able to install emacs on my X86_64 running Fedora 10.

Hi. I have Ubuntu 10.04, nm-applet is running in the background, my battery icon and sound icon are showing but my network icon has been missing for the past 2 days. It was working fine before but now it's not. How can I fix this issue if I don't have an ethernet cord? Is there a way to roll back the recent updates or do I need to reinstall my network manager?
I've tried restarting the system and I've tried killing nm-applet and reloading it using Alt F2. I get some Debug error.
When I try to run nm-applet --sm-disable
It says an instance is already running and then gives me a warning.
I tried removing "iface eth0 inet dhcp" from /etc/network/interfaces and then tried restarting by "sudo /etc/initi.d/networking restart"
It says:
What can I do to connect to the internet? I have a flash stick if its possible to download a .deb package on this mac and transfer it over to my other laptop to fix the problem. If its possible.
I presume there is something in the JWM window manager - or Puppy Linux Lupu 5.01 itself that is conflicting with the normal loading of GMPLAYER....
I would like to know how to troubleshoot, and fix this problem if possible (even a workaround would be great).
Sometimes I connect to my Debian box from another computer (using SSH on Cygwin or Linux), and once ina while I want to run some console apps. And sometimes some of these apps might complain about "another intance, Error: an instance of newsbeuter is already running (PID: 2496)". Is there a work around for this issue at all(without killing the original instance") ? The reason I do not want to kill the app because there might be 2 users connected to the same machine that might be using the same app.

We are running IPmonitor to monitor the disk usage on our Linux servers. It does not seem to coincide with what is reported when running df -h. For example on a Red Hat 5.3 server - our IPmonitor shows that 85% is used on the /usr partition, however when I do a df -h on the server it shows that 91% is used. Why there would be a discrepancy? IPmonitor uses SNMP.

My root Vixie cron crontab is set to perform a system snapshot via fsarchiver: 0 0 * * * fsarchiver savefs -o -A /backups/p30_root.fsa /dev/sda2 /dev/sda3 The command itself works fine, generating about a 7G snapshot of my Suse server. I then wish to rsync this to a NAS I have located in another building: 0 3 * * * rsync -av -e ssh --delete /backups/ root{at address}:/DataVolume/os_backups/
(yes, I'm rsyncing as root. I absolutely loathe it, but I got thrown into an quasi-SA position with a ridiculous to-do list and no time to do it. I'm having to make things just work and then go back and try to improve them/learn how. I couldn't make it work in a non-root way quick enough, so for now I'm having to cron rsync jobs as root because of all the differing file permissions on this samba/MySql server. I set the NAS to only accepts ssh from the server IP, and we're behind a campus firewall... It's serious trial by fire.) The crontab also has rsync commands for the samba areas, our specialized chemistry software and affiliated MySQL databases............
On my crontab there is an entry to run a script I wrote that backs up my local files to my remote server. It was working great, running once a day. However, I now want to make the script run every hour.The problem is that if there are too manyfiles to transfer (Example:I ripped a DVD in the last hour) the actual backup may take longer than 60 minutes.So I want to modify the script to check if my backup script, based on rsync, is running. If rsync is still running then do nothing and exit the script. If it is not running, execute the script as normal.
