.Sh NAME
.Nm sasyncd.conf
.Nd configuration file for sasyncd
.Sh DESCRIPTION
.Nm
is the configuration file for the
.Xr sasyncd 8
daemon.
.Pp
Comments can be put anywhere in the file using a hash mark
.Pq Sq # ,
and extends to the end of the current line.
.Pp
Since the file contains the shared secret key used to encrypt data
between this host and the others,
.Pa /etc/sasyncd.conf
must be owned either by
.Dq root
or the
.Dq _isakmpd
pseudo user and be readable only by this owner, e.g.\&
.Bd -literal -offset indent
# chown root /etc/sasyncd.conf
# chmod 0600 /etc/sasyncd.conf
.Ed
.Pp
The following configuration settings are understood:
.Bl -tag -width Ds
.It Ic carp interface Ar interface
Specify which
.Xr carp 4
interface
.Nm sasyncd
should track master/slave state on.
.It Ic carp interval Ar seconds
Specify how often the daemon should check the above interface for
state changes.
Defaults to once every 10 seconds.
