Home- table = rawio.ifconfig(interface)
- rawio.ifconfig(interface, table)
SYNOPSIS
DESCRIPTION
Functions for manipulating the configuration of network interfaces.
The first form returns a table that contains all items of the current interface configuration.
| Key | Value type | Description |
|---|---|---|
| broadcast | Boolean | True if this interface is able to handle broadcasts. |
| dynamic | Boolean | True if IP Address, Netmask, etc... is configured by DHCP. |
| ip | String | The IP address. |
| loopback | Boolean | True if this is a looped back interface. |
| mac | String | The hardware address. |
| metric | Number | The interface metric. |
| mtu | Number | The maximum transfer unit (Max. packet size.) |
| multicast | Boolean | True if this interface can handle multicasting. |
| netmask | String | The network mask in dotted quad format. |
| prefix | String | The network mask as number of prefix bits. |
| running | Boolean | True if the interface is enabled. |
| up | Boolean | True if the interface is enabled and properly configured. |
The second form allows changing configuration values. The passed value table accepts the same key/value pairs as shown above, only values that are to be changed must be present in the table.
RETURN VALUE
On success, returns a table containing key/value pairs. On error, three values are returned:
nil, a string describing the error (The result of the C library call strerror() on the
errno code) and the errno number from the standard C library.
