I am trying to get a process ( SARG access log report tool ) to run every 10 minutes but I cannot get it to work.
Here is the content of the crontab file

I am planning on running a script once every five minutes, and the syntax that comes to mind in doing this is the following:
Code:
5 10 15 20 25 30 35 40 45 50 55 * * * * /apps/<script>.pl
Is there a better syntax to use to accomplish this task, or is the above example the way to go?
I have and entry in a crontab for my user (appadmin) that when it executes it does not start with the proper path. It needs to start as the appadmin user as appadmin owns all the directories for glassfish. However, once glassfish restarts, the hudson application cannot find the default JDK. I get an error. If I initiate the restart via command line, all works as it should. I believe it has something to do with PATH in the crontab but am not sure what I need to set the PATH to in crontab.

I have a game server running using java, and it tends to crash sometimes, and only way to start it now is manually, so i thought i could create a script to check periodically if java is running, and if it isn't, run my startup script for the game server also, if it's possible it should log when it actually started the server startup script into a text file or something, so i can check why it crashed.

View 4 Replies View RelatedI have just installed Ubuntu for the first time using a USB drive and everything went fine during installation. However now during the boot phase I see 10 or so lines of
[14.24024] ata5: COMRESET failed (error=-16)
The numbers prior to COMRESET change with each line but the rest remains the same. I am extremely new to Ubuntu or Linux for that matter as this boot process is also taking about 3-4 or even 5minutes as it slowly cycles through each error. Once 10 or so lines have popped up the computer finishes starting and I can log in fine and everything.
What can I do about this?
Failed to execute child process "realplay" (No such file or directory)
using gdome Ubuntu, realplayer is in my Home folder (RealPlayer11GOLD)
Every time I boot up OpenSUSE 11.3 it hangs at the same "position" for approximately 3 minutes and then continues to boot. Unfortunately I see no corresponding error log e.g. in dmesg output. Hence, I don't know what is the reason for that. Here is my dmesg output. The delay occurs at 20 seconds after beginning of boot process (line 1085). I also analyzed the boot process with bootchart.
My computer: Notebook Lenovo ThinkPad R400.
I'm running a pretty heavy-weight process (Rails tests) that involves several worker processes, in an effort to parallelize the runs. To measure the performance impacts, I run hdparm -T /dev/sda to give me the cached read performance. Note that the disk IO is not being measured, but the disk cache IO is. It works very well on my work machine (8-core Mac Pro running Ubuntu with 8GB of RAM).
The baseline is:
honk4:~ $ sudo hdparm -T /dev/sda
/dev/sda:
Timing cached reads: 13224 MB in 2.00 seconds = 6616.86 MB/sec
In the middle of the test run:
honk4:~ $ sudo hdparm -T /dev/sda

I'm using mencoder to capture audio from a Encore ENLTV-FM3 video capture device. I have recently noticed that, since one week ago, when the machine was forcibly restarted due to a power outage, all recordings are slightly pitched, they play back slower than they should.
I narrowed down the problem to the following command line:
$ time mencoder -really-quiet -tv driver=v4l2:device=/dev/video1:chanlist=us-cable:audiorate=32000:alsa:adevice=hw.1:input=0:amode=1:normid=11 -endpos 00:10:00 -ovc copy -oac pcm -of rawaudio -o test-32000.wav tv://69
real 9m54.886s
user 0m5.536s
sys 0m1.740s
$ ls -l test-32000.wav
-rw-r--r--@ 1 martin martin 76800000 Mar 15 17:20 test-32000.wav
Somehow, mencode managed to gather precisely 10 minutes worth of raw audio in 9m 55s. That's not physically possible, unless the capture device's A/D converters are "overclocked". I can't think of any other explanation besides hardware failure. Can that be? Could it be that something got burnt during the power outage and now the capture device's internal clock went nuts?
Since the machine's restart, I've also noticed dmesg is flooded with entries like this:
CE: hpet increased min_delta_ns to XXX nsec
Which seem to indicate that the computer's high precision event timer is somehow out of sync. Does this have to do with the audio issue? Can it be that the audio converter's sample rate is linked to the HPET? I'm totally lost here. Has anyone bumped into something similar?
I am running ubuntu 10.04 as a web/file server. I have set up several cron jobs in the past which until recently were executing normally. However, a few days ago, cron jobs stopped executing after a restart. I was able to fix the problem by deleting and reentering the cron jobs, but only until the next restart. ps -ef lists cron.
Summary:
1.) Cron was working --jobs executed without error and restarts worked fine
2.) Cron jobs stopped executing after a restart about a week ago --ps -e still lists cron
3.) Removing all cron jobs and reentering them by copying and pasting fixes until next restart
4.) Cron job syntax is known to be correct since they were executing before this problem arose.
I want to execute a program at the very last step of Linux boot process. For Debian based Linux distro that uses BSD boot process, I came up with 2 solutions:
1) I should somehow call my program from the /etc/rc.local script (although is this the last step of the boot process?)
2) Use the "multi_end" and "sysinit_end" hooks for executing it at the end of rc.multi rc.sysinit respectively (I don't know how to do it though).
I want to monitor the process running and execute a command if some new process start. For example send a mail if any new process start.

I've just installed subversion.I need to create a script /etc/init.d/svnserve that will start at boot time.I want to use start-stop-daemon --start so I can track my process and eventually kill it using start-stop-daemon --stop.My problem is that I can't get it to work and the documentation shows no exemple.
I've replaced $DAEMON by the whole line: svnserve -d -R -r $REPO_ROOT and got -d is not an option.I'm not quite sure what to do at that point. If someone has some experience with start-stop-daemon it would be great.
Just figured this one out and thought I'd post it here in case it helped someone else. Skype just upgraded itself from 2.1 to 2.2. After upgrading it didn't start, and I got the message
"failed to execute child process skype-wrapper" First test out if skype runs from the command line, by running this in a terminal
Code: skype & If it runs, you're good to go: simply right click on the menu, locate your entry for skype and change the command to launch it from skype-wrapper to skype. The reason for this is that in the 2.1 version, skype needed a script called skype-wrapper to set some varibles before start up. Upgrading removes the script, but failed to update the menu entry.
I have a computation going which takes a long, but uncertain, amount of time. I have another computation which needs to be run, but _after_ the first one is done. I won't be at the computer at that time to manually start the new process. I've done some Googling, and I found how to delay execution by a specific amount of time (e.g. "start process x in exactly 8 minutes from now), but that isn't quite what I want to do. Essentially, I'd like to tell the shell, "When process #nnnn finishes running, then start process x". Is there a way to do this?

There seems to be a common solution to get the webcam working with Skype - rather than launching with Skype you launch with LD_PRELOAD=/usr/lib32/libv4l/v4l2convert.so skype - so far so good.

Now I am using Live CD.
I just updated from 9.04 to 9.10 (it's a long story, and I still can't go beyond 2.30).The update got rid of WICD, which is what I used and installed network-manager. Network-manager was not working at all, so I uninstalled it again and installed WICD. I could connect perfectly and had no problems.However, now the computer hangs during boot, saying that init can't start network-manager. I assume that something went wrong during the uninstalling process, since it wasn't updated.
This is the message: init: Failed to spawn network-manager main process: unable to execute: No such file or directory.
So how do I update it or manually change it so it stops requesting network-manager?
My machine is dual booted with Fedora 14 and RHEL 6. (I have only installed Red Hat because I am studying for RHCE). Just now I tried to install the Banshee player on my Red Hat OS. I ran various scripts inside the directory to see what really happens and after I ran the 'Makefile.in' file my terminal froze. It displayed '/bin/ not found'Then i restarted my computer and I got the following messages:
init: Failed to spawn readahead-collector main process: unable to execute: no such file or directory
init: Failed to spawn rcS main process: unable to execute: No such file or directory

I tried run level 1 and run level 3 but I get the same error messages.
PS: My Fedora 14 installation is working fine.
What is the difference between the crontab located in /etc/crontab and the crontab that can be edited using crontab -e?
