NAME    [Toc]    [Back]

       syslog.auth  -   authorization  file  for accepting remote
       syslog messages

SYNOPSIS    [Toc]    [Back]

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

DESCRIPTION    [Toc]    [Back]

       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`
