Re: Software program to access remote machine over TCP/IP network

Are you working on some kind of multifunctional? Where on one occasion you would send raw print data to the printer for printing, and on another you'd be trying to retrieve a network scan? I went through a similar process while reverse engineering drivers for Xerox multifunctionals a couple of years...

UDP is very similar to TCP but there are some fundamental mechanics differences.. For UDP server: Create a socket Bind !!

Re: about ncurses.h

How are you compiling this? Did you link to ncurses in your compile command? You need to add -lncurses so that the compiler knows to link against ncurses.. gcc -o test -lncurses test.c or use a Makefile. Here's a recent Makefile for a simple (C++) curses app: CC = g++ LIBS = -lcurses CFLAGS = -fperm...

Re: Motion: how it works and what (else) can it do?

Motion can be pretty CPU intensive though.. Don't get me wrong, it's awesome stuff, but in simple implementations it consumes, like, nearly a full CPU core per camera. It does in software what your camera couldawouldashoulda done in hardware. So considering the pi only has one core, for pi purposes ...

One thing way better than VNC is NX. You should definitely look into this for the simple reason that VNC is insecure.

That all looks awesome. In fact if your electronics skills are this high, you probably won't even need the powered USB hub (which by the way is indeed good and the dc converter also). But if you do get the hub, then yep you'll be converting 12V to 5V to power it. You can also branch off an existing ...

First things first, get yourself a powered USB hub and a DC-DC converter that can provide the DC volts the hub needs. Some adapters you can regulate with a dial, so if your hub needs 5V, you just turn the dial to 5V and Bob's your uncle. Cheap to get. Then hook everything up to that USB hub, includi...
