NethServer 6

Database: network_interfaces

Each entry describe a network interface according to CentOS/RHEL specification for network-scripts files:

<device_name> = type
     role = <role>
    <param> = <value>

• ethernet
• bond
• bridge
• alias
• ipsec (https://access.redhat.com/knowledge/docs/en-US/Red_Hat_Enterprise_Linux/4/html/Security_Guide/s1-ipsec-host2host.html)

• if the device is a physical ethernet device, the name will start with the role name followed by an optional ordering number. Eg: green, orange, red1, red2, ecc
• if the device is a logical device, name will be the standard one for the specific function. Eg: bond0, br0, br1, ecc

All ethernet devices are renamed using udev rules like (/etc/udev/rules.d/70-persistent-net.rules):

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="08:00:27:de:xx:xx", ATTR{type}=="1", KERNEL=="eth*", NAME="green" 

• green: local network, all services are exposed on this interface by default
• orange: DMS network
• blue: guest network
• red: external network, usually Internet
• yellow: reserved for private network (eg. cluster)
• empty: ethernet not assigned

• ippaddr
• hwaddr
• dhcp_hostname
• netmask
• slave
• ...

All parameters will be mapped 1-to-1 to the configuration file
