jos jedna stvar u prezentacijama je ova slika 
na netu sam pronasla ovu sliku 
odlomak parameter problem: "Code 0 defines that there is ambiguity in the header field of the datagram and the pointer field’s value of the parameter problem error message, points to the byte of datagram header, that has a problem.
Code 1 defines that the required part of the header is missing. Here, the pointer field is not used."
dakle icmp poruke o greskama u zaglavlju(parametrima datagrama) se po predavanjima ne salju, a google kaze da se salju… ofc “slusat” cu predavanja, ali ono wtf?
