NETDEV_NOTIFY_PEERS(9) Network device support NETDEV_NOTIFY_PEERS(9)NAME
netdev_notify_peers - notify network peers about existence of dev
void netdev_notify_peers(struct net_device * dev);
Generate traffic such that interested network peers are aware of dev, such as by generating a gratuitous ARP. This may be used when a
device wants to inform the rest of the network about some sort of reconfiguration such as a failover event or virtual machine migration.

s_n_d, set_net_default - select the default TCP/IP network
set_net_default: not found
This manual page is here because so many others refer to it. The set_net_default command does not exist under standard Minix, because the
TCP/IP server only supports one network. The server under Minix-vmd supports four different networks, that can each be chosen as the
The TCP/IP library and commands do have a notion about a "default network" however, because the code is shared between the Minix versions.
So if you want to venture into network programming then you should know about the devices and environment variables mentioned below to make
your program compatible. (Especially since there is a plan to upgrade the TCP/IP server for standard Minix.)
Options and environment to change the default
Many TCP/IP programs implement the following options and environment variables to change the default devices set by set_net_default. The
options are only implemented for low level programs where it makes sense to name a network device. The environment variables are used in
all code. You can run a process and all its children connected to a different network by setting four environment variables.
Device to use as raw ethernet device instead of the default /dev/eth.
Pseudo IP device to use instead of /dev/psip.
IP device to use instead of /dev/ip.
TCP device to use.
UDP device to use.
/dev/eth First and second raw ethernet.
/dev/psip First and second Pseudo IP network.
/dev/ip IP devices for two ethernets and two Pseudo IP networks.
/dev/tcp TCP devices for same four networks.
/dev/udp UDP devices.
/dev/eth, /dev/psip, /dev/ip, /dev/tcp, /dev/udp
Devices for the default network, links to the devices above. Eth is only present if ethernet is the default, psip only
for pseudo IP.
