Once Agian the LAIR my Friend and Foe and my Trial
Once Agian in the Lair and I have met the next generation of the Lair Kin and I fear that I have been out done yet agian. However this both hopefully and saddly my final 2 semesters in the LAIR im going to try once more to bury myself in my studies for the last semester I failed to improve my knowledege and understanding of the enviorment. I will be reteaching myself C and C++, java and bash while trying to complete my datacom Trials and my seemingly insurmountable opus of personal strife and achievement. I am a 3 yr veteran returning for a 4th yr and with out Certain Distractions keeping me from my goals and studies.

VoIP. Voice overlay Internet Proticol
a system and internet proticol that allows to transmite and receive human voice form one place to another much like the telephone which is analog but in order to use it via computer and the interwebs you need to digitize the sound wave length, tone and pitch of a human voice then transmit via the VoIP system which im not intirely sure of all that happens.
MAC Address
Arp
Mac address is the physical address put into and on a computer for its entire life this is not an IP which can be change no a Mac Adress is hard coded into the computer or networking device to reference it for future service such as allocating an ip to a network on the computer on either a WAN or a LAN. Media access control address ussaly given in a hexidecimal form
How to Find a Mac Address on a Windows XP Desktop PC or a Notebook PC • Click on START, and then click on RUN • The RUN dialogue box will appear. Type CMD and press ENTER • A DOS window will appear. This is also commonly called a Command Prompt • Now type IPCONFIG /ALL at the command prompt and hit ENTER. This window will now display the configuration of all of your network adapters. If you have multiple network adapters in your PC you'll see multiple addresses. The MAC Address you're looking for will be listed under the heading Ethernet Adapter Wireless Network Connection • Now look for the Physical Address. It should look something like 00-50-BA-D1-BA-71 • To close the window when you are finished, type EXIT at the command prompt and hit the ENTER key

Demonstration of the indicated keyword.
If you wish to aid your definition with a code sample, you can do so by using a wiki code block, an example follows:
/* * Sample code block */ #include <stdio.h> int main() { return(0); }
Alternatively (or additionally), if you want to demonstrate something on the command-line, you can do so as follows:
lab46:~$ cd src lab46:~/src$ gcc -o hello hello.c lab46:~/src$ ./hello Hello, World! lab46:~/src$
is there a known method to connect two analogue phones together to communicate with out the use of phone services or systems
no internet resourses how ever this experiment is one that has been done in the past in the same place by multiple inviduales all including the elusive presley suarues who has extensive experince in the home made cob job of analogue phone to phone
based on observatuions of preveouse atempts and experinces i belive that this is not only achiveable but easaly done knowning the right peramiters (ie an educated guess based on the facts known).
State your rationale.
Proof of previvuse exdperimentation and serveral retests and tests never been recorded however to my knowledge

Network Sockets
Network sockets are used to send and recive data via a out side source and are widely used for intenet applications and data comunications.
* Data coomuncations class
* and yes belive it or not we did touch on this in Cisco fundementals
* Beej's guid to network programing
thsi would be here if i knew a smaple cod ei could write to show this but only thing i have are other peoples work none of my oun yet still reading
Raspberry Pi is a mini perosnal computer not much larger then a smart phone. However the rasberry pi dose not have a screen nor a normal I/O busses system it has 2 micro USB 2.0 i belive and a single ethernet buss. With this and the right equipment a person who I know did this project named Andrew Sowers established that you could make a coffee pot brew a pot of coffee using the rasberry pi as an interfact with the on off switch, While using the asterisk pbx server to call in and tell the rasberry pi to turn on coffee mechine could brew coffee and in this he is showing that there are C and C++ libarys built into most standard libary packages that allow an interface with a basic appliance such as turn on and turn off. The more common reason they have this is when you shut down a computer your telling it do what you need to do save what you need to save and turn off all processing and programs and turn off the power supply and in this case more or less an applaince.
The Raspberry Pi hosts a General Purpose Input Output board for interfacing with low level peripherals. Dragon.net was nice enough to write a detailed C library for the GPIO to make electronics programming super easy! Here's an example of a program that turns on and off an LED:
/* * blink.c: * Simple test program to blink an LED on pin 7 */ #include <wiringPi.h> #include <stdio.h> int main (void) { int pin = 7; printf("Raspberry Pi wiringPi blink test\n"); if (wiringPiSetup() == -1) exit (1); pinMode(pin, OUTPUT); for (;;){ printf("LED On\n"); digitalWrite(pin, 1); delay(250); printf("LED Off\n"); digitalWrite(pin, 0); delay(250); } return 0; }
by way of this reference I hope to setup a simple c application using a solid state relay for my future automated “Dial a Coffee” via Asterisk and Pi ingenuity:http://elinux.org/RPi_Low-level_peripherals#GPIO_Driving_Example_.28C.29

Notes on Sip phone
Just for you Tom a step by step for using wine and installing and running Diablo 2 and Diablo 2 LOD
Using Argv and argc and scanf printf i can send and recive simple text by simply doing
argv argc promts user to type something tom command line then i use scanf and using a while loop with a termination varible so when your done messaging people you it will promt you after each message the only thing im having problem with is the lines of code being used to use a socket to send and recieve messages.
