Salut ,
Salut.
Primesc length errors de cateva zile. Am schimbat cablul,portul la sw si pana si eth0 in eth1. Inca nu am facut update de driver. Stiu ca astfel de erori rezulta atunci cand setarile de duplex nu sunt la fel. Aveti un sfat ?
Acele erori sint pe rx (receive). Deci, cineva din retea ti le trimite. Poate switch-ul pe care il ai iti poate spune (din statistici) ce port face asta. Teoretic nu ar trebui sa-ti forwardeze astfel de pachete.
Oricum, sint destul de putine, nu ar trebui sa-ti faci griji. Nu ai specificat ce tip de placa e. Dupa "a0:b3:cc" nu am gasit-o.E posibil sa fie si un bug in driver si sa i se para ca "vede" pachete mici.
Pachetele pare ca trec de placa de retea catre kernel, asa ca ar trebui sa logheze acele pachete. Nu vezi nimic cu 'dmesg'-ul?
Cred ca-l poti prinde si cu tcpdump-ul: tcpdump -nvvvli <interfata> less 59 Succes!
