Since a shockwave attack the other year I have lost my visual CRON job manager tool in WebMin.
When I click on the menu option “System > Scheduled Cron Jobs” I just get the following message
“The command crontab for managing user Cron configurations was not found. Maybe Cron is not installed on this system?”
However I know that CRON JOBS are running because
a) I have a CRON job that sends out bulk emails every morning and they are still being sent
b) I have CRON jobs for a number of plugins to fire them and they still work e.g building SiteMaps, Importing Feed Content and running TweetBOT jobs.
So I am guessing it’s a permission issue or something has been changed that is blocking WebMin from loading them up in GUI fashion.
When I login to a console and run
crobtab: command not found
If I run any of these
crontab -u user1 -l
crontab -u root -l
/usr/bin/crontab: Permission denied
When I run
I can see a list of users
When I run this
sudo ls -root /var/spool/cron/crontabs
I get back some information
-rw------- 1 user1 201 Oct 14 2011 user1
-rw------- 1 user2 1668 Jan 28 2014 user2
-rw------- 1 user3 1953 Oct 5 2014 user3
-rw------- 1 root 1592 Oct 7 2014 root
If I run this
ls -user1 /usr/bin/crontab
I get back
9240919 32 ---------- 1 root 32 Jun 1 07:03 /usr/bin/crontab
So the cron jobs are obviously there and assigned to users but I am guessing the permissions are incorrect for some reason which is why it doesn’t run in WebMin or load up in the console.
What commands should I run to restore the visual cron tab in WebMin or view the jobs in the console?
I have seen this article > http://serverfault.com/questions/78159/what-could-cause-permission-denied-for-command-crontab-e
But I don’t want to just start running commands willy nilly as I am not exactly a LINUX expert and don’t want to make things worse.
