/etc/sysconfig/samba

The

/etc/sysconfig/samba

file is used to pass arguments to the

daemon offers file sharing connectivity for Windows clients on the network. The

nmbd

daemon offers NetBIOS over IP naming services. For more information about what parameters

/etc/sysconfig/sendmail

The

the message over whatever networks are necessary. The file sets the default values for the Sendmail

application to run. Its default values are to run as a background daemon, and to check its queue once

an hour in case something has backed up.

The following values may be used:

  DAEMON= value

, where

value

is one of the following boolean values:

yes

  Sendmail should be configured to listen to port 25 for incoming mail.

implies the

use of Sendmail's

 bd

options.

no

  Sendmail should not be configured to listen to port 25 for incoming mail.

QUEUE=1h

which is given to Sendmail as

exists and

QUEUE

is empty or undefined.

is run. Sound card configuration information is located in the

/etc/modules.conf

file.

It may contain the following:

  CARDTYPE= value

, where

value

is set to, for example,

SB16

for a Soundblaster 16 sound

card.
