i cannot find it in the man. Is it possible to run cron job like this:
Run script from 18 00 till 5 00?
I want to run some script but only during the night time, when users are not working.
Previously I had posted a question on how to make it run every 7 minutes between 7 and and 11pm.However now I found out what I really need is every 7 minuted between 7:30 and 11pm BUT it has to be every 7 minutes, it cannot reset itself on the top of every hour, so the */7 wont work.How can it that it will be every 7 minutes, so it will go at 7:30, 37,44,51, 58, 8:05, etc..

I need to build a system that can provide me capacity to send more than 50.000 mails per hour. Now I have inherit a server farm with 40 postfix servers, and one server managing which of this servers send the mails but its programming for someone but it's too complex.

I have cron jobs running and the timing is critical, because I'm running Nessus scans on production servers. If I hit them at the wrong time, I'm toast. But when I check the cron log, I see that it is an hour off. Here is the output for the command "clock":
Wed 31 Mar 2010 03:01:26 PM CDT -0.257677 seconds
And this is the tail of the cron log:
Mar 31 16:00:01 nes-001 CROND[8790]: (root) CMD (/Nessus/Targets/NessusScriptDataCenterScan.test)
Mar 31 16:01:02 nes-001 CROND[8822]: (root) CMD (run-parts /etc/cron.hourly)

Mar 31 16:01:02 nes-001 run-parts(/etc/cron.hourly)[8834]: finished 0anacron
Cron thinks it is 4:00 p.m., but it's really 3:00 p.m. How do I tell Cron what time it is? (Stopping and restarting the crond service did not change it.)
I am attempting to schedule a task to run every hour. I have altered the crontabs for my account but the the task still won't run on the hour.

I recently install CentOS 5.5 on my small server. Unfortunately, I have problems with my mail configuration. I don't know anything about sendmail and dns configuration so I am just looking for something easy to set up. I use cron to perform automatic task. I set up the variable $MAILTO in cron to my regular mail. Cron send the mail but it is stuck in the queue.

View 8 Replies View RelatedRecently moved into amazon's ec2 cloud and noticed our server time was in UTC where we use EST. I did some looking around, and changed using the following;
Followed up setting the correct time using the date command with the correct time, then date showed;
Now, that is correct, but if I do an ntpdate pool.time.org or any other time server, the offset is huge and the date moves back one hour. Is this a daylight settings or something I am just missing?
It is the strangest thing. I can not receive emails on this server after it has been up for an hour. I noticed that everytime and email is received that a sshd opens but never closes. Causeing a memory issue that I dont know how to fix. Also the mailq grows and grows. Mostly with email stating the recipient and send are both [URL].. also postmaster@mail.jmchd.com shows mail system configuration error. I have to restart the server every 30 minutes so users can get and send emails. This is horrible because for every 5 minutes out of the hour emails are bouncing.i have looked through them but I know not what I am looking at.
PS. I was thrown into the position and have limited knowledge. I am used to a GUI.
Is 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).

View 5 Replies View RelatedI want to create some scheduled jobs in a CentOS server. These jobs are simple and repeatable, but the scheduling is complicated. I want a series of jobs to start every day but Monday, and not on the last day of the month. These jobs depend on software execution outside the server ( a Windows application) so if the Windows app fails, I need to temporarily suspend the cron jobs so I can straighten out the Windows server.
I've looked over some cron alternatives and nothing seems suitable. Am I stuck with cron and the limitations of crontab, or are there some programmatic things I can do in cron that I don't know about?

I'm having a very strange issue with cron on centos 5.3 64-bit. I have 3 cron scripts in /etc/cron.daily which run backups. They are as follows:
script1:
#!/bin/bash
/usr/local/bin/backup-script1
script2:
#!/bin/bash
/usr/local/bin/backup-script2
script3:
#!/bin/bash
/usr/local/bin/backup-script3
The contents of the 3 /usr/local/bin scripts are ...
/usr/local/bin/backup-script1:
#!/bin/bash
synbak -s srv1 -m rsync
rsync -av --delete /data/backup/srv1/* root@::share/srv1/
To explain this, the 1st active line does a synbak backup and the 2nd active line rsyncs the backup data to a remote server.
/usr/local/bin/backup-script2:
#!/bin/bash
synbak -s srv2 -m rsync
rsync -av --delete /data/backup/srv2/* root@::share/srv2/

pppd call isp Running it by hand, it dials out to my ISP and fetch all my email from different accounts and turn-off the link. It works great. I decided to automate the process using the cron.
The problem is when cron execute it at the specified time, nothing happens. It doesn't even dials out. I checked /var/log/cron and cron says It was executed. But it doesn't. I try again running the script by hand and works fine.
I have the following cron configuration in the 'crontab' file:

My focus is on the three WGET commands. The problem is the first one works fine, runs at 4:20 p.m., but the other two never run! If I visit [URL] it works fine but cron never runs it.
I made a big rookie mistake in a script in cron.daily, which emptied the directory when I tested it... now I'm left with an empty cron.daily directory, and from what I know there definitely were more scripts there than only my own.
