Hello all,

I have a server with Fedora core and I'm having problems with it.

I'm receiving 2 emails daily with the following subjects:

1) Cron <root@account> run-parts /etc/cron.daily
At the body of this email I have:

/etc/cron.daily/logrotate:

error: stat of /var/log/ppp/connect-errors failed: No such file or directory

The second email is:
2) LogWatch for mydomain.com

and here I have a lot of IP addresses trying to connect to my server...

Please I'm new on this Fedora world and I don't know how fix that...

Thanks you.

The first one is saying that it can't write to this error log. It's the log for your ppp (dial-up modem) connections. Open /etc/logrotate.d/ppp with a text editor and add this line if it isn't there:

Code: 
create 0600 root root

On the second one, you didn't say how they were trying to access your server. Which one, or what port?

Thanks you very much...

Ok, the second email is too big, so the resume is that I'm receiving about 500 emails like spam... to an account that i have configured in case of someone send an email to an account that not exist on the domain.

On that account I'm receiving daily about 500-700 emails from different people and sometimes with the same subject and sometimes with other subject like: re[21]... etc.

Please I'm desperate with this problem...

Thanks you.

Rather than create an account for this type of mail you can reject it. Which mail server do you use?

you should be able to drop those connections by using
the /etc/hosts.deny file . Just put in the subnet that you want to drop (make sure it ends in a . (dot)

ALL: 200.11.78.
ALL: 200.147.105.
ALL: 200.171.182.
ALL: 200.179.

Make sure to check your logs after for any misconfig


works great for me
