       l2tp-secrets - L2TPD secrets file


       The  l2tp-secrets  file contains challenge-response authentication information for xl2tpd,
       the implementation of l2tp protocol.  The format of the file is derived from the  pap  and
       chap secrets file format used in pppd.

       The  secrets  file  is  composed  of  zero  or  more  lines with 3 fields each.  Each line
       represents an authentication secret.  The 3 fields  represent  our  hostname,  the  remote
       hostname and the secret used in the authentication process.

       The first field is for our hostname, a "*" may be used as a wildcard.

       The  second  field  is  for  the  remote system's hostname.  Again, a "*" may be used as a

       The third field is the secret used if the previous two fields match the hostnames  of  the
       systems  involved.  The secret should, ideally, be at 16 characters long (the length of an
       MD5 digest output), and should probably be longer to ensure sufficient security.  There is
       no minimum length requirement, however.
