Only announce the server and listen to requests on network

interface <replaceable>IF</replaceable>. Default is to
160
use all available interfaces. <emphasis>Note:</emphasis>
161
a failure to bind to the specified interface is not

If this option is used, the server will only listen to a

174
an IPv4 address can be specified using the
175
<quote><literal>::FFFF:192.0.2.3</literal></quote> syntax.
176
Also, if a link-local address is specified, an interface
177
should be set, since a link-local address is only valid on

all available addresses.

run more than one server on the same

<emphasis>host</emphasis>, which would not normally be

useful. If there are name collisions on the same
245

246
automatically rename itself to <quote><literal>Mandos

not needed in that case.

fact, been compromised by parties who may now be running a

fake Mandos client with the keys from the non-encrypted
524
initial <acronym>RAM</acronym> image of the client host. What
525
should be done in that case (if restarting the server program
