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
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.
