\begin{description}

\item[\textbf{Name}] \mbox{}

This is a short identifier for the scheme. If more than
one scheme has the same identifier, then the first
occurence takes precedence. Schemes shown with brackets
around the name are system defaults that cannot be
changed. The scheme named "def\_dialup" will be used as a default
for dialup connections. Schemes can be disabled by
postfixing the name with *.

\item[\textbf{Description}] \mbox{}

An optional description of the scheme.

\item[\textbf{Interfaces}] \mbox{}

A (space-separated) list of interfaces for which this
scheme is appropriate. If this field is blank, the
scheme is a candidate for all interfaces. Use "ppp0"
for schemes which are intended only for dialup.

\item[\textbf{Wireless Net}] \mbox{}

The name of a wireless network to which the scheme
should be applied. If this is blank, the scheme applies
only to wired interfaces. The name may be prefixed with
/ad-hoc for an ad-hoc network (default is "/managed").

\item[\textbf{AP Address}] \mbox{}

A (space-separated) list of access point MAC addresses
for which this scheme is valid. By default, schemes are
valid for any AP. Mac Addresses must have the form
XX:XX:XX:XX:XX:XX.

\item[\textbf{WEP Key}] \mbox{}

The WEP encryption key for this wireless network as a
hex string, or in the form "s:PASSWORD". If this is
blank, no encryption is performed. This field is
ignored for wired networks.

\item[\textbf{Netmask Size}] \mbox{}

The size (in bits) of the netmask for this network. If an
explicit IP address is specified, the default value is
determined from the given IP address. If no explicit IP
address is given, this value is ignored and the value
supplied by DHCP/PPP is used.

\item[\textbf{Script}] \mbox{}

The name of script to execute when this scheme is
detected. The name of the scheme is passed as an
argument, and the script is run with the uid of the
user owning the scheme file. The script is executed in
the background with input and output to /dev/null.

\item[\textbf{SMTP Server}] \mbox{}

The name of a host to use as the mail relay. Local mail
will always be delivered via the local sendmail program
which will forward it to this relay. If this is blank,
then the LCFG-defined default mail relay will be used.
Setting this to "localhost" will cause the local sendmail
to deliver mail directly; this is usually necessary when
connected to a foreign network.

\item[\textbf{Context}] \mbox{}

A context to be passed to the LCFG profile
component. This can used to tune the system
configuration towards the type of connection. The
default is set by the defcontext resource (normally
"net=remote").  The additional context "scheme=ID" is
also selected.

\item[\textbf{IP Address}] \mbox{}

The IP address (or hostname) to which the host should
be configured if this scheme is detected. If this is
blank, then DHCP will be used in an attempt to
determine the host address. If a name is specified
in the LCFG (rather than an IP number), then the name
must be available in the local DNS server. This field
is ignored for dialup schemes and the IP address is
determined via PPP.

\item[\textbf{Probe Addresses}] \mbox{}

The IP address (or hostname) of one or more well-known
hosts (eg. the gateway) to be probed to identify this
scheme. If this is blank, the scheme will be applied as
a default if all others fail. Note that more than one
default scheme is not meaningful, unless they are on
different wireless networks. If a name is specified in
the LCFG (rather than an IP number), then the name must
be available in the local DNS server. This field is not
used for dialup connections.

\item[\textbf{Gateway}] \mbox{}

The IP address (or hostname) of the gateway
corresponding to this scheme.  This value is set
automatically if DHCP is being used (IP field is
blank), or when using a dialup scheme. If a name
is specified in the LCFG (rather than an IP
number), then the name must be available in the
local DNS server. The special value <route> indicates
that the existing default values for the routing
component will be used to set up the routing.

\item[\textbf{DNS Servers}] \mbox{}

The IP addresses (or hostnames) of DNS servers to use
with this scheme. These hosts will be used as
forwarders by the local DNS server which is always
queried first. If this is blank, then the default
forwarders will be used. If it is *, then no forwarders
will be set.  If a name is specified in the LCFG
(rather than an IP number), then the name must be
available in the local DNS server. If left blank,
DHCP and PPP will supply these values automatically.
