NAME

       netctl.profile - Profile options

SYNOPSIS

       netctl.profile

DESCRIPTION

       Profiles for netctl live under /etc/netctl/ and are plain text files. The files consist of
       variable definitions following the bash shell syntax and are not expected to execute any
       code. It is good to omit as much quoting as possible. For a few WPA-related variables,
       special quoting rules (see below) apply.

       The name of the profile is the name of the file. Profile names must not contain newlines
       and should not end in .action, .conf, or .service. Whenever a profile is read, all
       executable scripts in /etc/netctl/hooks/ and any executable script in
       /etc/netctl/interfaces/ with the name of the interface for the profile are sourced. The
       name of the current profile is available via the Profile variable in the environment of
       the sourced scripts. On starting or stopping a profile, the respective command is
       available via the Command variable. Declarations in an interface script override
       declarations in a profile, which override declarations in hooks. For each connection type,
       there are example profile files in /etc/netctl/examples/.

AVAILABLE CONNECTION TYPES

       ethernet
           For wired connections.

GENERAL OPTIONS

       Description=
           A description of the profile.

       Connection= [mandatory for all profiles]
           The connection type used by the profile.

       Interface= [mandatory for all profiles]
           The name of the associated network interface. The interface name should not be quoted.

       BindsToInterfaces=()
           An array of physical network interfaces that this profile needs before it can be
           started. For ‘enabled’ profiles, systemd will wait for the presence of the specified
           interfaces before starting a profile. If this variable is not specified, it defaults
           to the value of Interface=.

       After=()
           An array of profile names that should be started before this profile is started. This
           is only an ordering dependency and is not intended to be a list of profiles that this
           profile requires. The meaning is the same as After= in systemd.unit(5).

       WaitOnline=
           Set to ‘yes’ to consider the profile activated only when it is online. Defaults to
           ‘no’.

       ExecUpPost=
           A command that is executed after a connection is established. If the specified command
           returns anything other than 0 (success), netctl will abort and stop the profile. If
           the command should be allowed to fail, add ‘|| true’ to the end of it.

       ExecDownPre=
           A command that is executed before a connection is brought down. Similar precautions
           should be taken as with ExecUpPost=.

       TimeoutUp
           Maximum time, in seconds, to wait for an interface to get up. Defaults to ‘5’.

       ForceConnect=
           Set to ‘yes’ to force connecting even if the interface is up. Do not use this unless
           you know what you are doing.

       ExcludeAuto=
           Whether or not to exclude this profile from automatic profile selection. Defaults to
           ‘no’ for wireless and DHCP enabled connections and to ‘yes’ otherwise.

       NETCTL_DEBUG=
           Set to ‘yes’ to generate debugging output.

IP OPTIONS

       These options apply to all connections that set up an IP-enabled network. In particular,
       these connection types are ethernet, wireless, bond, bridge, tunnel, tuntap, and vlan.

       IP= [mandatory for IPv4]
           One of ‘static’, ‘dhcp’, or ‘no’, depending on the desired way of obtaining an
           address.

       IP6= [mandatory for IPv6]
           One of ‘static’, ‘stateless’, ‘dhcp-noaddr’, ‘dhcp’, ‘no’ or left out (empty)
           altogether. The difference between not specifying and setting to ‘no’ is in the
           handling of router advertisement packages, which is blocked by ‘no’.

       Address=() [requires IP=static]
           An array of IP addresses suffixed with ‘/<netmask>’. Leaving out brackets for arrays
           consisting of a single element is accepted in the Bash syntax.

       Gateway= [requires IP=static]
           An IP routing gateway address.

       Routes=()
           An array of custom routes of the form

           ‘<address range> via <gateway>’.

       Address6=() [requires IP6=static or IP6=stateless]
           An array of IPv6 addresses. Prefix length may be specified via ‘1234:bcd::11/64’
           syntax. It is possible to specify modifiers, in particular, ‘1234:bcd::11/64 nodad’
           disables Duplicate Address Detection for the address.

       Gateway6= [requires IP6=static or IP6=stateless]
           An IPv6 routing gateway address.

       Routes6=()
           An array of custom routes of the form

           ‘<address range> via <gateway>’.

       DHCPClient= [requires IP=dhcp]
           The name of the DHCP client to use. Clients may accept additional options through
           client-specific variables. By default, netctl comes with support for ‘dhcpcd’ and
           ‘dhclient’. Defaults to ‘dhcpcd’.

       DHCP6Client= [requires IP6=dhcp or IP6=dhcp-noaddr]
           The name of the DHCPv6 client to use. By default, ‘dhcpcd’ and ‘dhclient’ are
           supported. Defaults to ‘dhclient’.

       DHCPReleaseOnStop=
           Set to ‘yes’ to release the DHCP lease when the profile is stopped.

       IPCustom=()
           An array of argument lines to pass to ip. This can be used to achieve complicated
           configurations within the framework of netctl.

       Hostname=
           A transient hostname for the system.

       DNS=()
           An array of DNS nameservers. Simply specify the IP addresses of each of the DNS
           nameservers.

       DNSDomain=
           A ‘domain’ line for /etc/resolv.conf, passed to resolvconf(5).

       DNSSearch=
           A ‘search’ line for /etc/resolv.conf, passed to resolvconf(5).

       DNSOptions=()
           An array of ‘options’ lines for /etc/resolv.conf, passed to resolvconf(5).

       TimeoutDHCP=
           Maximum time, in seconds, to wait for DHCP to be successful. Defaults to ‘30’.

       TimeoutDAD=
           Maximum time, in seconds, to wait for IPv6’s Duplicate Address Detection to succeed.
           Defaults to ‘3’.

       SkipDAD=
           Whether or not to bypass Duplicate Address Detection altogether. Defaults to ‘no’.

       SkipNoCarrier=
           Whether or not the absence of a carrier (plugged-in cable) is acceptable. Defaults to
           ‘no’.

       Priority=
           Priority level of the profile. In case of automatic profile selection, profiles are
           tried in decreasing order of priority. Defaults to ‘1’ in DHCP enabled profiles and to
           ‘0’ otherwise.

OPTIONS FOR ‘WIRELESS’ CONNECTIONS

           is not already present).

       Priority=
           Priority group for the network. In case of automatic profile selection, the matched
           network with the highest priority will be selected. Defaults to ‘0’.

       WPAConfigSection=() [mandatory for Security=wpa-configsection]
           Array of lines that form a network block for wpa_supplicant. All of the above options
           will be ignored.

           succeed. Defaults to ‘15’.

       RFKill=
           The name of an rfkill device. When specified, the device is used to block/unblock the
           interface when appropriate. Names can be found in /sys/class/rfkill/rfkillX/name. It
           is also possible to set this variable to ‘auto’. In that case an rfkill device that is
           associated with the network interface is used.

OPTIONS FOR ‘BOND’ CONNECTIONS

       The interfaces of BindsToInterfaces= are bound together in the interface named by
       Interface=. Next to the ip options, the following is understood for connections of the

       following are understood for connections of the ‘tunnel’ type:

       Mode=
           The tunnel type (e.g. ‘sit’). See ip-tunnel(8) for available modes.

       Local=
           The address of the local end of the tunnel.

       Remote=
           The address of the remote end of the tunnel.

           A key identifying an individual traffic flow within a tunnel.

OPTIONS FOR ‘TUNTAP’ CONNECTIONS

       The name of the tuntap interface is specified in Interface=. Next to the ip options, the
       following are understood for connections of the ‘tuntap’ type:

       Mode=
           Either ‘tun’, or ‘tap’.

       User=
           The owning user of the tun/tap interface.

       Group=
           The owning group of the tun/tap interface.

OPTIONS FOR ‘VLAN’ CONNECTIONS

       The name of the vlan interface is specified in Interface=. The underlying physical
       interface is specified in BindsToInterfaces=. Hence, for vlan profiles, BindsToInterfaces=
       contains the name of a single network interface.

       All options for connections of the ‘ethernet’ type are understood for connections of the
       ‘vlan’ type. Additionally, connections of the ‘vlan’ type must set a vlan identifier using
       VLANID=. See ip(8) for details.

OPTIONS FOR ‘MACVLAN’ CONNECTIONS

       The name of the macvlan interface is specified in Interface=. The underlying physical
       interface is specified in BindsToInterfaces=. Hence, for macvlan profiles,
       BindsToInterfaces= contains the name of a single network interface.

       All options for connections of the ‘ethernet’ type are understood for connections of the
       ‘macvlan’ type. Next to the ip options, the following are understood for connections of
       the ‘macvlan’ type:

       Mode=
           Either ‘bridge’, ‘vepa’, ‘private’, or ‘passthru’. See ip(8) for details.

       MACAddress=
           Optional static MAC address for the ‘macvlan’ type link.

SPECIAL QUOTING RULES

       Configuration files for wpa_supplicant use non-standard quoting. Therefore, non-standard
       quoting rules exist for some variables for connections of the ‘wireless’ type. In
       particular, these variables are ESSID=, and Key=.

       A variable is considered quoted by wpa_supplicant if it is enclosed in double quotes (").
       A variable is considered non-quoted by wpa_supplicant if it does not start with a double
       quote. Hexadecimal values are specified non-quoted in configuration files of
       wpa_supplicant. In netctl, variables are written to wpa_supplicant configuration files
       quoted by default. When special quoting rules apply, it is possible to specify an unquoted
       (hexadecimal) value using a special syntax.

       The special quoting rules of netctl are as follows. A string that starts with a literal
       double quote is considered non-quoted. Any other string is considered quoted. It is
       possible to specify quoted strings that start with a double quote by quoting manually. An
       extreme example is the specification of a quoted double quote: X='""""'. On the other end
       of the spectrum there is the non-quoted backslash: X=\"\\.

       Further examples of quoted strings (all equivalent):

           X=string
           X="string"
           X='""string"'

       Further examples of non-quoted strings (all equivalent):

           X=\"string
           X="\"string"
           X='"string'

       A mnemonic is to think of the prefix ‘\"’ as saying ‘non’-‘quote’.
