====== /etc ======



===== /etc/hosts =====



Current version:

<code>

# The first line should be left alone.  It seems

#   to be an important default.   MXM, SJ

127.0.0.1				localhost localhost.localdomain 

#

# The name of our machine (lamentably) is "tighar".

# The fully qualified domain name of the machine

#   is tighar.tighar.org

===== /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.



===== /etc/passwd =====

====== STD files ======

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

|  STDIN|0|

|  STDOUT|1|

|  STDERR|2|

\\ 

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."
