Crontab authentication failure

UNIX for Advanced & Expert Users

Dear all,
I noticed in syslog that i receive authentication failure from cron:

Mar 11 23:19:01 s1 CRON[28789]: Authentication failure
Mar 11 23:19:01 s1 cron[682]: Authentication failure
Mar 11 23:19:01 s1 cron[682]: Authentication failure
Mar 11 23:19:01 s1 CRON[28787]: Authentication failure
Mar 11 23:19:01 s1 CRON[28788]: Authentication failure
Mar 11 23:19:01 s1 cron[682]: Authentication failure

How can I check what caused that and why there are two "crons"?

There are also other cron entries in syslog:

Mar 11 23:19:01 s1 CRON[28793]: (web123) CMD (/usr/bin/php5 -q /var/www/web123/web/yii/console/yiic.php email #domain.com)
Mar 11 22:46:01 s1 CRON[24149]: (root) CMD (/usr/local/ispconfig/server/server.sh 2>&1 > /dev/null | while read line; do echo `/bin/date` "$line" >> /var/log/ispconfig/cron.log; done)

Recently i had issue with dovecot/postfix mailuser rights, maybe this could be the issue, but i do not know what to look for.

Please post your exact crontab file entries for these two users:

  • root
  • web123

We need to see the exact crontab file entry to give you the help you are asking for.

Thanks.

Thanks for reply.
Here's crontab -l for root :

* * * * * /usr/local/ispconfig/server/server.sh 2>&1 > /dev/null | while read line; do echo `/bin/date` "$line" >> /var/log/ispconfig/cron.log; done
30 00 * * * /usr/local/ispconfig/server/cron_daily.sh 2>&1 > /dev/null | while read line; do echo `/bin/date` "$line" >> /var/log/ispconfig/cron.log; done

any other jobs are comented out.

I could not find any of the cron jobs for user web123
crontab -u web123 -l no crontab for web11 , even if they appear in syslog

Why are you posting questions and answers here at unix.com with two usernames (two accounts)?

Thanks.
