detectNetworkInterfaceRate(device, cmd='/usr/sbin/ethtool')

Function Details

Return the next IP address on a network range, or an empty string

Parameters:

network (str) - dotted quad IP representation
netmask (int) - number of bits in netmask
startAt (str) - IP from which to get the next IP
boundaries (bool) - flag telling whether the network address and the broadcast address are also returned

Returns: str

an IP address in dotted quad representation, or an empty string

Get all network device interfaces using /proc. Linux only.

Use ethtool to detect network device rate. We can use the given rate only if:

the link is up on the device (if the link is down, the device is on low speed mode, and this speed may change when the link is up again)
auto-negociation is on (else the speed information can't be really trusted)

Returns: int: interface rate in kbit/s, or None if the rate can't be detected
