MANDOS.CONF(5)

NAME
mandos.conf - Configuration file for the Mandos server

SYNOPSIS

/etc/mandos/mandos.conf

DESCRIPTION

The file /etc/mandos/mandos.conf is a configuration file for mandos(8), and is read by it at startup. The configuration file starts with “[DEFAULT]” on a line by itself, followed by any number of “option=value” entries, with continuations in the style of RFC 822. “option: value” is also accepted. Note that leading whitespace is removed from values. Lines beginning with “#” or “;” are ignored and may be used to provide comments.

OPTIONS

interface = NAME
    If this is specified, the server will only announce the service and listen to requests on the specified network interface. Default is to use all available interfaces. Note: a failure to bind to the specified interface is not considered critical, and the server will not exit, but instead continue normally.

address = ADDRESS
    If this option is used, the server will only listen to the specified IPv6 address. If a link-local address is specified, an interface should be set, since a link-local address is only valid on a single interface. By default, the server will listen to all available addresses. If set, this must normally be an IPv6 address; an IPv4 address can only be specified using IPv4-mapped IPv6 address syntax: “::FFFF:192.0.2.3”. (Only if IPv6 usage is disabled (see below) must this be an IPv4 address.)

port = NUMBER
    If this option is used, the server will bind to that port. By default, the server will listen to an arbitrary port given by the operating system.

debug = { 1 | yes | true | on | 0 | no | false | off }
    If the server is run in debug mode, it will run in the foreground and print a lot of debugging information. The default is to not run in debug mode.

priority = STRING
    GnuTLS priority string for the TLS handshake. The default is

    “SECURE128:!CTYPE-X.509:+CTYPE-RAWPK:!RSA:!VERS-ALL:+VERS-TLS1.3:%PROFILE_ULTRA” when using raw public keys in TLS, and “SECURE256:!CTYPE-X.509:+CTYPE-OPENPGP:!RSA:+SIGN-DSA-SHA256” when using OpenPGP keys in TLS,. See gnutls_priority_init(3) for the syntax. Warning: changing this may make the TLS handshake fail, making server-client communication impossible. Changing this option may also make the network traffic decryptable by an attacker.

servicename = NAME
    Zeroconf service name. The default is “Mandos”. This only needs to be changed if for some reason is would be necessary to run more than one server on the same host. This would not normally be useful. If there are name collisions on the same network, the newer server will automatically rename itself to “Mandos #2”, and so on; therefore, this option is not needed in that case.

use_dbus = { 1 | yes | true | on | 0 | no | false | off }
    This option controls whether the server will provide a D-Bus system bus interface. The default is to provide such an interface.

use_ipv6 = { 1 | yes | true | on | 0 | no | false | off }
    This option controls whether the server will use IPv6 sockets and addresses. The default is to use IPv6. This option should never normally be turned off, even in IPv4-only environments. This is because mandos-client(8mandos) will normally use IPv6 link-local addresses, and will not be able to find or connect to the server if this option is turned off. Only advanced users should consider changing this option.

restore = { 1 | yes | true | on | 0 | no | false | off }
    This option controls whether the server will restore its state from the last time it ran. Default is to restore last state.

statedir = DIRECTORY
    Directory to save (and restore) state in. Default is “/var/lib/mandos”.

socket = NUMBER
    If this option is used, the server will not create a new network socket, but will instead use the supplied file descriptor. By default, the server will create a new network socket.

FILES

The file described here is /etc/mandos/mandos.conf

BUGS

The [DEFAULT] is necessary because the Python built-in module ConfigParser requires it.

Please report bugs to the Mandos development mailing list: <mandos-dev@recompile.se> (subscription required). Note that this list is public.

EXAMPLE

No options are actually required:

    [DEFAULT]

An example using all the options:

    [DEFAULT]
    # A configuration example
    interface = enp1s0
    address = fe80::aede:48ff:fe71:f6f2
    port = 1025
    debug = True
    priority = SECURE128:!CTYPE-X.509:+CTYPE-RAWPK:!RSA:!VERS-ALL:+VERS-TLS1.3:%PROFILE_ULTRA
    servicename = Daena
    use_dbus = False
    use_ipv6 = True
    restore = True
    statedir = /var/lib/mandos

    Section 2.2: Text Representation of Addresses

    Section 2.5.5.2: IPv4-Mapped IPv6 Address

    Section 2.5.6, Link-Local IPv6 Unicast Addresses
        The clients use IPv6 link-local addresses, which are immediately usable since a link-local addresses is automatically assigned to a network interface when it is brought up.

Zeroconf[1]
    Zeroconf is the network protocol standard used by clients for finding the Mandos server on the local network.
