Daily reports

Once your server running, you must make sure everything works fine. Do not read any further if you don't plan to maintain it. Luckily, OpenBSD developpers made things easier.

Every day (infact every night) a report from "Charlie Root" is generated and mailed to user "root". Inside, you can find :

I look like this:

You can read warning about file owners and changes in a file. Lines starting with "+" were added, those starting with a "-" removed.

In this example, at last, a checksum on the password database has changed : did you add a new user?

Well, that's nice, but how do I get it?

As you will see, it's very easy :

Of course, replace with a mail address you read daily.

Then, run "# newaliases".

That's it! 😄

Just to make sure, send yourself a test message :

echo "Hello sweetie!" | mail -s "test" root

You should get this mail at the address written in /etc/mail/aliases.

Now, it's up to you to read these report every day.

If you need to, you can change the domain name of the sender if you edit /etc/mail/mailname. As example :


File system check

Add this line to /etc/daily.local to check filesystems every day :
