# The first line should be left alone.  It seems

#   to be an important default.   MXM, SJ

/etc/logwatch/conf/logwatch.conf

What reports should be made to root@tighar.org?

Default configuration: /usr/share/logwatch/default.conf/logwatch.conf

MailFrom = root

/etc/mailname

According to mailname(5), the /etc/mailname file should contain

the “the visible mail name of the system” and is usually used by

“programs that wish to send or relay mail, and need to know the

name of the system.” More specifically:

  • The file contains only one line describing the fully qualified

domain name that the program wishing to get the mail name should

use (that is, everything after the @).

We don't have this file on our system. If we have troubles with

sendmail, it's something we might try.

STD files

Every process has a minimum of three standard streams associated with it:

STDIN0
STDOUT1
STDERR2


The numbers associated with these STD file streams often appear in command lines. 2>&1 says “redirect the output for STDERR to wherever the output for STDOUT is going.”
