network configuration

network adapters

The network configuration is found in the service script /etc/rc.d/net. By default this service script is not configured to connect to the network.
Example:

# ----------------------------------------

# ipv4 config options for eth0, eth0.10 or bond0
IFNAME[0]=""
IFADDRS[0]=""
USE_DHCP[0]=""
DHCP_HOSTNAME[0]=""

# ipv4 config options for eth1, eth1.10 or bond1
IFNAME[1]=""
IFADDRS[1]=""
USE_DHCP[1]=""
DHCP_HOSTNAME[1]=""

# ipv4 config options for eth2, eth2.10 or bond2
IFNAME[2]=""
IFADDRS[2]=""
USE_DHCP[2]=""
DHCP_HOSTNAME[2]=""

# ipv4 config options for eth3, eth3.10 or bond3
IFNAME[3]=""
IFADDRS[3]=""
USE_DHCP[3]=""
DHCP_HOSTNAME[3]=""

# ipv4 default gateway ip address
GW=""

# ----------------------------------------

To enable a network with dynamic address acquisition (dhcp), you must specify the network interface and enable the use of dhcp:

IFNAME[0]="eth0"
IFADDRS[0]=""
USE_DHCP[0]="yes"
DHCP_HOSTNAME[0]=""

To set up a static address, perform the following settings:

IFNAME[0]="eth0"
IFADDRS[0]="192.168.0.1/24"
USE_DHCP[0]=""
DHCP_HOSTNAME[0]=""

# ipv4 default gateway ip address
GW="192.168.0.1"

wifi network adapters

To configure Wi-Fi adapters, you must configure the following settings in the file /etc/rc.d/wlan:

# ----------------------------------------

# ipv4 config options for wlan0
IFNAME[0]=""
IFADDRS[0]=""
USE_DHCP[0]=""
DHCP_HOSTNAME[0]=""

# ipv4 config options for wlan1
IFNAME[1]=""
IFADDRS[1]=""
USE_DHCP[1]=""
DHCP_HOSTNAME[1]=""

# ipv4 default gateway ip address
GW=""

# ----------------------------------------

To enable a network with dynamic address acquisition (dhcp), you must specify the network interface and enable the use of dhcp:

IFNAME[0]="wlan0"
IFADDRS[0]=""
USE_DHCP[0]="yes"
DHCP_HOSTNAME[0]=""

And also configure /etc/rc.d/wpa_supplicant, add or change adapter names, space separator:

IFNAME=(wlan0 wlp3s0)

You also need to set up authorization in /etc/wpa_supplicant.conf:

network={
   ssid="register the name of the access point"
   scan_ssid=1
   key_mgmt=WPA-PSK
   psk="register a password"
}

The wpa_supplicant package provides two startup scripts in /etc/rc.d.
You might choose to put wlan in the SERVICES array of /etc/rc.conf, which will let wpa_supplicant manage all your network interfaces.
Another option is to let the net startup script call wpa_supplicant as needed, by copying into /lib/dhcpcd/dhcpcd-hooks/ the example file /usr/share/dhcpcd/hooks/10-wpa_supplicant.

dns settings

You will also need to configure DNS settings in /etc/resolv.conf:

#
# /etc/resolv.conf: resolver configuration file
#

search your internal domain>
nameserver your DNS server>

# End of file

vlan network adapters

To configure VLAN interfaces, you must install the vlan package.
The VLAN ID is taken from the full interface name, which is comprised of the nderlying interface name, a period (.) and then the VLAN ID.
IFOPTS is a pipe (|) delimited list of VLAN module specific settings to be applied to the interface.
See the ip-link(8) man page (search for “VLAN Type Support”) for details of the options available.
This option is not required for a standard VLAN to be configured.

# ----------------------------------------

# config options for eth0.10
IFNAME[0]="eth0.10"
IFOPTS[0]=""

# config options for eth1.10
IFNAME[1]=""
IFOPTS[1]=""

# config options for eth2.10
IFNAME[2]=""
IFOPTS[2]=""

# config options for eth3.10
IFNAME[3]=""
IFOPTS[3]=""

# ----------------------------------------

After configuring interfaces, they must be specified in /etc/rc.d/net so that these interfaces can receive an address.
To configure this service vlan at system startup, add it before the net in the SERVICES array of /etc/rc.conf.

bonding network adapters

To configure bond (link aggregation) interfaces, you must install the bonding package.
Parameter description:
- BONDNICS is a space delimited list of interfaces to add to this bond.
- BONDMODE sets the bonding mode for this interface. If not specified when has been used, the default is ‘balance-rr’.
- IFOPTS is a pipe (|) delimited list of bonding module specific settings to be applied to the interface, and should always include the ‘miimon’ option when configuring bonding - not using this option will result in network degradation. In ‘active-backup’ mode, the ‘primary’ option should also be supplied. When using ‘802.3ad’ mode, set “lacp_rate fast” for faster recovery from an interface failure. In other modes, the ‘xmit_hash_policy’ should be set.
See the https://www.kernel.org/doc/Documentation/networking/bonding.txt.

# ----------------------------------------

# ipv4 config options for bond0
IFNAME[0]="bond0"
BONDNICS[0]="eth0 eth1"
BONDMODE[0]="balance-rr"
IFOPTS[0]="xmit_hash_policy layer2+3 | miimon 100"

# ipv4 config options for bond1
IFNAME[1]=""
BONDNICS[1]=""
BONDMODE[1]=""
IFOPTS[1]=""

# ----------------------------------------

After configuring interfaces, they must be specified in /etc/rc.d/net so that these interfaces can receive an address.
To configure this service bonding at system startup, add it before the vlan or net in the SERVICES array of /etc/rc.conf.
