Vohljač za SAS on-line komunikacijo

GOJTANIĆ, ANDREJ (author), Bulić, Patricio (mentor)

V okviru diplomskega dela je bilo potrebno razviti vohljač, ki posluša komunikacijo med dvema računalnikoma. Prebranim podatkom doda določene parametre in vse skupaj pošlje na tretji računalnik. Za to smo razvili vezje, ki je priključeno neposredno na komunikacijski kabel, preko katerega potujejo podatki med dvema računalnikoma. Na vezju je mikrokrmilnik, ki prebrane podatke shrani, jim doda vse parametre ter vse skupaj pošlje na tretji računalnik. Na njem se izvaja program, ki je prav tako bil razvit za ta projekt, v katerem so podatki prikazani kronološko. Na ta način lahko vidimo, kje in kdaj je prišlo do napake.

• Title: A sniffer for SAS on-line communication

Abstract

In the thesis, a sniffer had to be developed, which is listening the communication between two computers. It saves all the data, includes some other parameters and sends everything to a third computer. For this, a circuit board was developed, that is directly connected to the communication line used by the two computers. There is a microcontroller on it, which stores all the read data, appends all of the parameters and sends everything to the third computer. An application that was also developed for this project is running on the third computer, which displays the data received chronologically. In such a way we can find when and why an error happened.
