machine ipaddress = 192.168.0.1
Domain name = testing.com

I installed RHEL 5 today and set my network. Did it as follows:Eth0 connectionPrimary DNS 192.168.1.1When I click on Activate, it says:8139too device eth0 does not seem to be present, delaying initialization.This message shows no matter how many times I log out or restart.I don't know what the heck is the problem. I've done the essentials but still it's not working. I looked up on the net but people were saying things like ifconfig and lspci, and at the end still weren't able to solve it. I don't know all this since I'm new to Linux. Another important thing...after facing this same problem some time ago, I installed Centos which asked for internet settings right at the time of installation. And after logging in for the first time, I was able to use internet without any problem. How come internet works on Centos (which is a copy of RHEL) without any problems, but not working on RHEL itself?

View 3 Replies View RelatedI have a question about using crontab with /etc/crontab...
I had a cron job that I needed to run as root. At the time I thought that sticking it in /etc/crontab would be a good idea. However, I used the crontab command to edit /etc/crontab, which I guess is not standard procedure? Specifically, I configured /etc/crontab as my local user's crontab (i.e. sudo crontab /etc/crontab) then added my cron job as I would a local user crontab (i.e. sudo crontab -e).
Originally, my cron job looked like this:
30 * * * * root /my/batch/script &> /dev/null
After adding the new cron job I started seeing errors. Something to the effect of "can't find command root" or something similar. So I removed the 'root' user definition from the cron job and the job started running fine. However, because this is /etc/crontab, there are other system related cron jobs that have been defined to run under the root account (e.g. "17 * * * * root cd / && run-parts --report /etc/cron.hourly" runs as root, etc.). So these pre-existing system cron jobs, which up until now have been running smoothly, are now generating "can't find command root" errors. But I think that the system cron jobs _are_ successfully being run someplace because logrotate seems to be working.
So what I _think_ is happening is that /etc/crontab is being run twice: once as the system crontab, and once as my sudoed local user's crontab. When I run crontab -l I see nothing, but when I run sudo crontab -l I can see the contents of /etc/crontab. I am reluctant to delete my sudoed local user's crontab, because then in the process I would be deleting the system crontab, and I do not know how I should restore the system crontab's contents. (I am still not sure as to the most appropriate way to edit the system crontab).
How can I get out of this mess? I want /etc/crontab to go back to the way it was before--running _once_ as the system crontab. As for my new cron job, I'm willing to reconfigure it anywhere so long as I am still able to run it as root. Any ideas? (I am using Ubuntu 8.04 Server LTE)

View 4 Replies View RelatedI setup a cron job to trigger a script that I wrote every morning at 12:00 AM, but it does not seem to be working.
This is how I edit the job using crontab -e
Why it isn't triggering at 12:00 am every night. If I run the script manually it works just fine so I know is not the script causing troubles.
I know crontab -e sets a cronjob in /var/spool/cron but how do I set a cronjob to run from /etc/crontab? Is there a command used for this or would I have to manually edit a certain file?

View 5 Replies View RelatedMy laptop's clock (Acer Extensa 5220) seems to be slow. I've corrected it 5 minutes forward last week and now have just corrected minute forward again. Is there a program [apart from time servers] to correct clock properly, for example, by shifting it a bit every hour? Is there already a program to put it to crontab or I should hack up a script? Or I should check more things?
I have found that HW clock is right, but system time is slow: about a second each 2.1 hours.

Is placing "hwlock --hctosys" to crontab a right thing?
Im new to linux, using ubuntu 10.04. I have been playing around with crontab and have no problems scheduling a job which runs a script file containing the following command:
However, when I try to do the following in the script file nothing happens..
Similarly the following doesnt do anything either:
Is there something im missing?
Silly question here. My crontab looks like this:
Quote:
0 22 * * * /usr/sbin/logrotate /var/log/VRTSralus/VRTSralus.logrotate
#0-59/10 * * * * /root/memmon.sh >> /var/log/memmon.txt
0 8 * * 1 /root/SHC.sh
#0 21 * * * /root/scripts/ralus_restart.sh > /dev/null 2>&1
As you can see two of the lines are commented out. However, both commented out commands are still running. I get emails stating that the RALUS agent restarted (another mystery since it's supposed to go to dev null according to the line above), and I can see that the memmon script is also running daily. Am I missing a step? Some other place I should be looking? Commenting out lines in your crontab is pretty much a no-brainer, so I appear to have less than no brain as this is a mystery to me.
I am setting crontab to run a script every minute irrespective of the current hour's value:
Code:
[root@localhost bin]# ls
sec.php showTime.sh
[root@localhost bin]# crontab -l
1 * * * * /root/bin/showTime.sh
[root@localhost bin]#
But it is not working. Does the line mean: "Run this script every day at hour:01"?
I'm running Ubuntu server 8.04.3 with eBox on a Dell GX280. I want to power off my box automatically every night, so as root I added a crontab entry "05 1 * * * /sbin/shutdown -P now". The command runs on schedule but most days the PC goes into a coma instead of powering off. It doesn't respond to key presses or mouse movement or Ctrl-Alt-Delete, I have to push its power button to complete the shutdown. I have tried a variety of alternatives such as "/sbin/shutdown -h" and "runlevel 0", they all behave the same way
