[SOLVED] email only received from logwatch

qwertyjjj · 08-11-2009, 04:23 AM

I am receving emails from logwatch but when I setup my own mail script using mutt, the script succeeds but no email is received.
Any ideas what the difference is between the two mail methods?

Perhaps you can tell us how you set it up ?
Look in the logfiles for errors

Look in the logfiles or errors

just like this:

I ran the test commands and no errors were given so I'm thinking an email service or something? But then why would logwatch send successfully?

1st step:
check /var/log/maillog to see if any mail was ever sent out. logwatch sends email to root user.
are you doing the same?

I did that but there are only 10 lines in there using tail -f.
Anyway to view the whole logfile?
I changed the MailTo command in the logwatch.conf to an actual email address.

repo · 08-11-2009, 06:04 AM

Code:

cat /var/log/maillog | more

or
open a terminal and type

Code:

tail -f /var/log/maillog

open a second terminal and execute the script

change mailto in crontab too. by default it sends to the root user

Code:

/var/spool/mail/root

change this in your crontab

Code:

MAILTO=emailaddress

Script and test as per: http://www.syntaxtechnology.com/?p=83
Have changed MAILTO in /etc/crontab as well but that's separate from this SystemEmail script.
Comes up with this in the log.

Forgive the elementary questions:

1.) The script uses mutt to send emails

Code:

echo "${SHUTDOWNBODY}" | mutt -s "${SHUTDOWNSUBJECT}" ${EMAIL}

. Do you have mutt installed?
2.) There is a variable at the top of the script. Did you change it from example@example.com to your address?

Code:

EMAIL="example@example.com"

3.) What distro are you attempting this from? I assume CentOS from the information under your username, but I just wanted to make sure.
4.) When running either

Code:

./SystemEmail start
or
./SystemEmail stop

what is the output of

Code:

echo $?

If the return code is zero, does root receive a returned email with failure reason?

5.) If you run (using your email address)

Code:

echo "TEST BODY" | mutt -s "TEST SUBJECT" example@example.com

does it work?

mylog.log contains nothing this morning.
Is it possible the crontab didn't write to it using this code?
The sarg reports ran correctly...just nothing after that...

Code:

01 * * * * root run-parts /etc/cron.hourly
02 4 * * * root run-parts /etc/cron.daily
22 4 * * 0 root run-parts /etc/cron.weekly
42 4 1 * * root run-parts /etc/cron.monthly
00 23 * * * root /usr/bin/sarg
00 00 * * * root /etc/cron.daily/0logwatch 2 >> /root/mylog.log
00 01 * * * root /bin/tar -cvvf /root/backup-`/bin/date +%d%m%Y`.tar /etc /var/log /var/www /usr/lib/squid/ncsa_auth 2 >> /root/mylog.log
10 01 * * * root /bin/gzip /root/backup-'/bin/date +%d%m%Y'.tar 2 >> /root/mylog.log

Yes, in /usr/bin/mutt.

Yes, centOS.

what is the output of

Code:

echo $?

When I run those commands from the prompt, there is no output at all. It just returns with a new prompt line.

I ran this and just received a new prompt but no email as yet.

---------------------
When I run this directly from the command line, it goes into some kind of editor?????
mutt -s "TEST" email@myactualemailaddress.com

Also, the logs said something about:
postdrop: warning: unable to look up public/pickup: No such file or directory

While doing this, in another terminal type

Code:

tail -f /var/log/mail.log

what is the output from the command logged in as root ?

Code:

mail

Mail sent to root arrives in root's inbox.
You can change this by editing
/etc/aliasses
root:username

But logwatch uses sendmail doesn't it?
Like I said, the command works, just not when run from crontab?! Strange

Same error as before:
Aug 12 11:44:22 localhost postfix/postdrop[2894]: warning: unable to look up public/pickup: No such file or directory

repo · 08-12-2009, 07:10 AM

It uses the MTA installed.
