interface <replaceable>IF</replaceable>. Default is to

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

considered critical, and the server does not exit.

172
If this option is used, the server will only listen to a

specific address. This must currently be an IPv6 address;
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
178
a single interface. By default, the server will listen to
179
all available addresses.

this may make the TLS handshake fail, making communication

with clients impossible.

239
Zeroconf service name. The default is

241
to be changed this if it, for some reason, is necessary to
242
run more than one server on the same
243
<emphasis>host</emphasis>, which would not normally be
244
useful. If there are name collisions on the same

<emphasis>network</emphasis>, the newer server will
246
automatically rename itself to <quote><literal>Mandos

restarting servers if it is suspected that a client has, in

523
fact, been compromised by parties who may now be running a
567
524
fake Mandos client with the keys from the non-encrypted
568
initial RAM image of the client host. What should be done in
569
that case (if restarting the server program really is
570
necessary) is to stop the server program, edit the
525
initial <acronym>RAM</acronym> image of the client host. What
526
should be done in that case (if restarting the server program

really is necessary) is to stop the server program, edit the

configuration file to omit any suspect clients, and restart
