I've just discovered that crontab is creating a new file in the root directory every time it executes a cronjob, and it doesn't erase over the old file so there are thousands of files in the root directory, they have the same name as the script file (appended with a numeral) but are all blank.here is what one of the cronjob's looks like[URL]
View 10 Replies View RelatedI 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 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)

BACKGROUND:
My local subnet (NAT'ed by my gateway router) is 192.168.52.x. My router has been configured with a conduit (port-forward) for port 1194 (the standard OpenVPN port), which points towards my CentOS server.The CentOS server is .52.112, and the supplicant is .52.110.

View 4 Replies View RelatedIs there something that blocks cron from running a shutdown command? I'm doing a daily bounce to break an attack (I have thread about that in security forum), but I always end up doing it manually. The cron log shows it being fired off at the right time...but the server never bounces. I thought maybe I just missed it, but there is nothing in messages that shows the server restarting (unlike when i do it manually, you see the start-up logging).

I have installed Centos and after few days I used it as a web server, database server (MySQL) and have some very important for me applications installed.
Today - I have read about "yum -update" function and I (a dummy one...) tried it. After some minutes the process was finished. But unfortunatelly - my server did not boot any more.
As startup options I have:
CentOS (2.6.18-164.6.1.el5)
CentOS (2.6.18.-164.6.1.el5PAE)
CentOS (2.6.18-128.2.1.el5PAE)
CentOS (2.6.18-128.2.1.el5)
CentOS (2.6.18-128.1.14.el5)
CentOS (2.6.18-92.el5)
I'm not sure what are these options. Anyway - I have tried to choose every one and the result is aways the same : red Hat Nash version 5.1.19.6 starting
Then starts the clock [ok],
Then starts the "udev" [ok]
And then My screen goes to suspend mode, with the text "no signal".
The most important thing is to backup the data from the hard disk. Do I have any chance to repair this installation ?

[Errno 14] HTTP Error 407: Proxy Authentication Required
Error: Cannot find a valid baseurl for repo: addons
i export the proxy but still not working,
1) Installed Cent os 5.4 in my system (name it as "guest os").
2) Downloaded the full kernel source, and patched the vanilla kernel to export symbol table (2 line change) [URL] (Yes I know that kernel should not be touched, if touched you should not seek help here . but I felt I didnt do any big change in kernel there). Besides we unset the config_smp & config_preempt parameter to make the kernel as not SMP and not preemptive .
3) Then compiled and booted with the new kernel 2.6.18, everything went fine . Now my gust os box is loading fine and I dont have any issue .
So now I need to install this above machine as guest OS in one more XEN machine cent os 5.4 (name it as "xen os").
So we created the image out of the above box "guest os" and added it as VM in xen os . But while booting it always hangs under some error like "/usb device sort of thing" (I dont have the screen where it hangs, but I do have the equivalent xen log from XEN OS linked to [URL] .
1) what the error is, and what need to be changed in my guest os build .
2) In general I am new to this VM and XEN installation, to be frank I am completely zero . Does changing the native os 5.4 to guest os need any change in kernel or something.
3) Does this case possible, install plain cent os in xen machine. After then patch the kernel in VM and boot with that . I guess it should not be possible ...
4) If possible guide me to some documentation where I can learn few basics over this.
After reviewing the dmesg log, I realize that it does not log all startup messages. Is there a way to configure it or another log to do so?

I am trying to monitor a Centos 5.3 box using SNMP and I am having a lot of trouble getting the data that i need from it. Everytime I try to get information from the UCD-SNMP MIB it returns "End of MIB". It is my understanding that UCD-SNMP is a standard package when Net-SNMP is installed and should always be there. Then why can't I access it? I have tried removing the reinstalling Net-SNMP, but that hasn't worked. My server is update date on all it's patches as well. It is quite old hardware, but I don't believe that should affect SNMP from being gathered. Iptables is down, and I cant' even get it from the local machine.
