l2tp-secrets(5)						       l2tp-secrets(5)

NAME
       l2tp-secrets - L2TPD secrets file

DESCRIPTION
       The l2tp-secrets file contains challenge-response authentication infor‐
       mation 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  authenti‐
       cation 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 wildcard.

       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.
