NAME

       syslog.auth -  authorization file for accepting remote syslog messages

SYNOPSIS

       # format:  Each fully qualified host name on a separate line hostname.domain_name

DESCRIPTION

       The /etc/syslog.auth file specifies which remote hosts are allowed to forward syslog messages to the local host.  For the sake of security,
       only messages coming from remote hosts listed in the local /etc/syslog.auth file will be logged by the syslogd daemon.

       If the /etc/syslog.auth file does not exist, then messages coming from any host will be accepted.

       Each remote host name should appear in a separate line in /etc/syslog.auth. A line started with the # character is considered as a  comment
       and is thus ignored.

       A  host	name  must be a complete domain name such as trout.zk3.dec.com. If a domain host name is given, it must either appear in the local
       /etc/hosts file or be able to be resolved by the local name server (BIND).

       Note that a host name can have at most as many characters as defined by the  MAXHOSTNAMELEN constant in <sys/param.h>, although	each  line
       in the /etc/syslog.auth file can have up to 512 characters.

       The /etc/syslog.auth file must be owned by root and has a permission of 0600.

       To invoke a new version of the /etc/syslog.auth file, run the following command (as the super user) to initialize the  syslogd daemon: kill
       -HUP `cat /var/run/syslog.pid`

EXAMPLES

       The  following  example	provides  a  typical  authorization  file:  #  format:	 Each  fully  qualified  host  name  on  a  separate  line
       c3poid.rvo.dec.com r2d2id.ckt.dec.com
