It is a very good point the MTU length, first of all thank you for this info because I didn't know , but when I tested the program, many messages arrived to the server , before the incomplete message i guess that the large of the message was more large that the message because even the first message should not have come.
Thank you very much for the information Corona688

I am attempting to write a *basic* network client in C. I have manage to create a socket but I have doubts as far as using AF_INET vs AF_UNIX.
At the present time, my client runs with AF_INET. Is AF_UNIX faster across hosts using the same OS flavor (Red Hat)? What is the difference... (1 Reply)

SET_NET_DEFAULT(8) System Manager's Manual SET_NET_DEFAULT(8)
NAME
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.
