s_n_d, set_net_default - select the default TCP/IP network SYNOPSIS
set_net_default: not found DESCRIPTION
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 default network. 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. ETH_DEVICE=device -E device Device to use as raw ethernet device instead of the default /dev/eth. PSIP_DEVICE=device -P device Pseudo IP device to use instead of /dev/psip. IP_DEVICE=device -I device IP device to use instead of /dev/ip. TCP_DEVICE=device -T device TCP device to use. UDP_DEVICE=device -U device UDP device to use. FILES
/dev/eth[01] First and second raw ethernet. /dev/psip[01] First and second Pseudo IP network. /dev/ip[0123] IP devices for two ethernets and two Pseudo IP networks. /dev/tcp[0123] TCP devices for same four networks. /dev/udp[0123] 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. SEE ALSO
ip(4), boot(8). AUTHOR
