This module implements a generic ethernet interface. To function correctly it needs an ethernet driver to be loaded, so that the module can use the driver to access the underlying hardware.
The link between the eth module and the ethernet driver is established without the programmer intervention by the driver itself.
Translate a host name to IPv4 address format. The IPv4 address is returned as a string, such as “192.168.0.5”.
select(rlist, wlist, xlist, timeout=None)
This is equivalent to the Unix
select system call. The first three arguments are sequences of socket instances.
rlist: wait until ready for reading
wlist: wait until ready for writing
xlist: wait for an “exceptional condition” (not supported by every wifi driver)
Empty sequences are allowed. The optional
timeout argument specifies a time-out as an integer number in milliseconds. When the
timeout argument is omitted the function blocks until at least one socket is ready. A
timeout value of zero specifies a poll and never blocks.
The return value is a triple of lists of objects that are ready: subsets of the first three arguments. When the time-out is reached without a socket becoming ready, three empty lists are returned.
Activate the Ethernet PHY and try to establish a link.
An exception can be raised if the link is not successful.
Disable the Ethernet PHY and disconnect from the currently linked network.
Return True if linked
set_link_info(ip, mask, gw, dns)
Set desired eth interface parameters:
ip, the static ipv4 address
mask, the network mask
gw, the default gateway
dns, the default dns
If 0.0.0.0 is given, a default address will be used.
Return information on the currently established link.
The result is a tuple where the elements are, in order:
The assigned IP as a string
The network mask as a string
The gateway IP as a string
The DNS IP as a string
The MAC address of the eth interface as a sequence of 6 bytes
