DESCRIPTION

The purpose of rc.conf is not to run commands or perform system startup actions directly. Instead, it is included by the various generic startup scripts in /etc which conditionalize their internal actions according to the settings found there.

The /etc/defaults/rc.conf file specifies the default settings for all the available options, the /etc/rc.conf file specifies override settings. Options need only be specified in /etc/rc.conf when the system administrator wishes to override the defaults. The file /etc/rc.conf.local is used to override settings in /etc/rc.conf for historical reasons. In addition to /etc/rc.conf.local you can also place smaller configuration files for each rc(8) script in the /etc/rc.conf.d directory, which will be included by the load_rc_config function. For jail configurations you could use the file /etc/rc.conf.d/jail to store jail specific configuration options. Also see the rc_conf_files variable below.

The following list provides a name and short description for each variable that can be set in the rc.conf file. To set a variable of bool type, specify either “YES”, “TRUE”, “ON”, or “1”. To unset, specify “NO”, “FALSE”, “OFF”, or “0”. These values are case insensitive. The _enable postfix in the name of a variable for starting a service can be omitted (as in NetBSD).

icmp_drop_redirect

(bool) Set to “NO” by default. Setting to “YES” will cause the kernel to ignore ICMP REDIRECT packets. Refer to icmp(4) for more information.

icmp_log_redirect

(bool) Set to “NO” by default. Setting to “YES” will cause the kernel to log ICMP REDIRECT packets. Note that the log messages are not rate-limited, so this option should only be used for troubleshooting networks. Refer to icmp(4) for more information.

icmp_bmcastecho

(bool) Set to “YES” to respond to broadcast or multicast ICMP ping packets. Refer to icmp(4) for more information.

ip_portrange_first

(int) If not set to “NO”, this is the first port in the default portrange. Refer to ip(4) for more information.

ip_portrange_last

(int) If not set to “NO”, this is the last port in the default portrange. Refer to ip(4) for more information.

ifconfig_⟨interface⟩

(str) Configuration for “interface”. Typically includes IP address. Assuming that the interface in question was ed0, it might look something like this:

ifconfig_ed0="inet 10.0.0.1 netmask 0xffff0000"

If the /etc/start_if.⟨interface⟩ file is present, it is read and executed by the sh(1) interpreter before configuring the interface as specified in the ifconfig_⟨interface⟩ and ifconfig_⟨interface⟩_alias⟨n⟩ variables.

It is possible to bring up an interface with DHCP by adding “DHCP” to the ifconfig_⟨interface⟩ variable. For instance, to initialize the ed0 device via DHCP, it is possible to use something like:

ifconfig_ed0="DHCP"

If a vlans_⟨interface⟩ variable is set, a vlan(4) interface will be created for each item in the list with the vlandev argument set to interface. If a vlan interface's name is a number, then that number is used as the vlan tag and the new vlan interface is named interface.tag. Otherwise, the vlan tag must be specified via a vlan parameter in the create_args_⟨interface⟩ variable.

To create a vlan device named em0.101 on em0 with the vlan tag 101 and the optional the IPv4 address 192.0.2.1/24:

vlans_em0="101"
ifconfig_em0_101="inet 192.0.2.1/24"

To create a vlan device named myvlan on em0 with the vlan tag 102:

vlans_em0="myvlan"
create_args_myvlan="vlan 102"

If a wlans_⟨interface⟩ variable is set, an wlan(4) interface will be created for each item in the list with the wlandev argument set to interface. Further wlan cloning arguments may be passed to the ifconfig(8) create command by setting the create_args_⟨interface⟩ variable. One or more wlan(4) devices must be created for each wireless devices as of DragonFly 2.5. Debugging flags for wlan(4) devices as set by wlandebug(8) may be specified with an wlandebug_⟨interface⟩ variable. The contents of this variable will be passed directly to wlandebug(8).

Also, if your interface needs WPA authentication, it is possible to add “WPA” to the ifconfig_⟨interface⟩ variable. This will start wpa_supplicant(8). See wpa_supplicant.conf(5) for configuring authentication information.

Finally, you can add ifconfig(8) options in this variable, in addition to the /etc/start_if.⟨interface⟩ file. For instance, to initialize the wi0 device via DHCP, using WPA authentication and 802.11b mode, it is possible to use something like:

wlans_wi0="wlan0"
ifconfig_wlan0="up DHCP WPA mode 11b"

ifconfig_⟨interface⟩_alias⟨n⟩

(str) Configuration to establish an additional network address for “interface”. Assuming that the interface in question was ed0, it might look something like this:

ifconfig_ed0_alias0="inet 127.0.0.253 netmask 0xffffffff"
ifconfig_ed0_alias1="inet 127.0.0.254 netmask 0xffffffff"

And so on. For each ifconfig_⟨interface⟩_alias⟨n⟩ entry that is found, its contents are passed to ifconfig(8). Execution stops at the first unsuccessful access, so if something like this is present:

ifconfig_ed0_alias0="inet 127.0.0.251 netmask 0xffffffff"
ifconfig_ed0_alias1="inet 127.0.0.252 netmask 0xffffffff"
ifconfig_ed0_alias2="inet 127.0.0.253 netmask 0xffffffff"
ifconfig_ed0_alias4="inet 127.0.0.254 netmask 0xffffffff"

Then note that alias4 would not be added since the search would stop with the missing alias3 entry.

ifconfig_⟨interface⟩_name

(str) New name for “interface”. It is possible to rename interface by doing:

ifconfig_ed0_name="net0"
ifconfig_net0="inet 10.0.0.1 netmask 0xffff0000"

netif_enable

(bool) Set to “YES” by default. Setting to “NO” will disable the configuration of network interfaces.

network_interfaces

(str) The list of network interfaces to configure on this host, or “auto” to configure all network interfaces (default “auto”). For example, if the only network devices to be configured are the loopback device (lo0) and a NIC using the em(4) driver, this could be set to “lo0 em0”. An ifconfig_⟨interface⟩ variable is assumed to exist for each value of interface.

ipv6_network_interfaces

(str) This is the IPv6 equivalent of network_interfaces. Instead of setting the ifconfig variables as ifconfig_⟨interface⟩ they should be set as ipv6_ifconfig_⟨interface⟩. Aliases should be set as ipv6_ifconfig_⟨interface⟩_alias⟨n⟩. Interfaces that do not have a ipv6_ifconfig_⟨interface⟩ setting will be auto configured by rtsol(8) if the ipv6_gateway_enable is set to “NO”. Note that the IPv6 networking code does not support the /etc/start_if.⟨interface⟩ files.

ipv6_prefix_⟨interface⟩

(str) Assign prefix to interface, prefixlen 64 is used.

ipv6_default_interface

(str) If not set to “NO”, this is the default output interface for scoped addresses. Now this works only for IPv6 link local multicast addresses.

ip6addrctl_enable

(bool) This variable is to enable configuring the default address selection policy table (RFC 3484). The default value is “YES”, and the policy table to be installed is specified by the ip6addrctl_policy variable below.

ip6addrctl_policy

(str) This variable specifies the policy table to be installed, and can be one of the following keywords: “ipv4_prefer”, “ipv6_prefer”, or “AUTO” (default).

If “ipv4_prefer” or “ipv6_prefer” is specified, ip6addrctl(8) installs a pre-defined policy table described in Section 2.1 (IPv6-preferred) or 10.3 (IPv4-preferred) of RFC 3484.

If “AUTO” is specified, it attempts to read a file /etc/ip6addrctl.conf first. If this file is found, ip6addrctl(8) reads and installs it. If not found, a policy is automatically set according to ipv6_enable variable; if the variable is set to “YES” the IPv6-preferred one is used. Otherwise IPv4-preferred.

ip6addrctl_verbose

(bool) If set to “YES”, print the installed policy table after configuring. The default value is “NO”.

(str) Set to the list of clonable network interfaces to create on this host. Entries in cloned_interfaces are automatically appended to network_interfaces for configuration.

gif_interfaces

(str) Set to the list of gif(4) tunnel interfaces to configure on this host. A gifconfig_⟨interface⟩ variable is assumed to exist for each value of interface. The value of this variable is used to configure the link layer of the tunnel according to the syntax of the tunnel option to ifconfig(8). Additionally, this option ensures that each listed interface is created via the create option to ifconfig(8) before attempting to configure it.

sppp_interfaces

(str) Set to the list of sppp(4) interfaces to configure on this host. A spppconfig_⟨interface⟩ variable is assumed to exist for each value of interface.

fsck_y_enable

(bool) If set to “YES”, fsck(8) will be run with the -y flag if the initial preen of the file systems fails.

netfs_types

(str) List of file system types that are network-based. This list should generally not be modified by end users. Use extra_netfs_types instead.

extra_netfs_types

(str) If set to something other than “NO” (the default), this variable extends the list of file system types for which automatic mounting at startup by rc(8) should be delayed until the network is initialized. It should contain a whitespace-separated list of network file system descriptor pairs, each consisting of a file system type as passed to mount(8) and a human-readable, one-word description, joined with a colon (‘:’). Extending the default list in this way is only necessary when third party file system types are used.

A value of 2-10 seconds will substantially reduce network traffic for many NFS operations. The default is 5 seconds. Note that the attribute cache holds stat information only. The NFS data cache is independent of the attribute cache and is only invalidated when the client detects that the server has modified the underlying file. This value specifies a maximum timeout. The NFS client will automatically use a shorter timeout for files which have been recently modified.

nfs_neg_cache

(int) If nfs_client_enable is set to “YES”, this can be set to “0” to disable the caching of NEGATIVE LOOKUPS (lookups of non-existent filenames), or to the number of seconds for which negative lookups should be cached.
