Nu prea. In primul rand ca ma pierd in `'`'`' pe acolo, si in alte cele.
La mine al 8-lea camp nu este size-ul (adica nu este deloc). In fine,
trecand peste asta:
gawk '/13:39:29/ {sum += $6} END {print sum}' (poti sa pui si _*_ 8,
daca vrei in kilobiti)
In al doilea rand, de ce imparti kilobytes la 8, ca sa-ti dea kilobiti?
In al treilea rand, aia 42 sunt marimea payload-ului UDP. Adica la aia
42 se adauga inca 8 din header-ul UDP, cel putin 20 la IP si inca ceva
la datalink (Ethernet are 14, parca).
REVENIND! Cum bagi tu 200pps in 3kB/s?
