Note: Corrected commandline for launching the server Jan 20, 2013 -rs

An afterthought:
While poking around in this stuff I found this warning in the linux/if_ether.h header.

Code:

#define

Sockets - A Packet Snooper With A QT4 GUI (Req's libLQ-qt/mc2 dload) Part 1

Today's feature is

Running a packet snooper in an lqMiniTerm 'run' loop function.

[Note: the lqMiniTerm is evolving a bit and will continue to evolve for a while as we experiment and discover things that come up over and over that are easier to address in the mini terminal than in the main() file's code. Currently term_printf() is a candidate for becoming a miniterm feature. Find out why! :-) ]...

Sockets - Bidirectional Communication IPv4/6 (terminal version)

Today's features:

More fun with sockets.
Bidirectional communication using IPv4 and IPv6 socket streams (sequential).
Interactive. (Only interprets one command, but it's easily expandable.)
Terminal version for broader usefulness.

[Note the addresses in this and the previous sockets experiments (here http://www.linuxquestions.org/questi...example-35270/)...

Sockets - UDP RX (recieve/transmit) terminal example
Today's feature:

A UDP file server and client using linux sockets.
A terminal app for those who don't have libLQ-qt and mc2.

[This is for our LQ-less friends. A libLQ version using a qt gui but NOT qt sockets should be forthcoming shortly.]

This upload is pushing the size limit but it's interesting to see how the broadcast channel is set up (in inc/broadcast-rx.c) and how the parts of the files are picked up...

mini-term in qt4

mini-term in qt4.

Today's features:

A simple terminal-like application built from a qt4 class that can be used for other stuff too.
The present application can run shell commands and has copy/paste (ctrl-c, ctrl-v) capabilitity.
Another example of the Windows-like api so that C/C++ code can run in Qt4.
Runs the custom code (terminal in this case) inside a QT 'exec' loop... sorta. We call it 'run()'.
