Ciao a tutti,
da qualche giorno ho notato un notevole rallentamento nella mia
connessione internet.
Siccome in precedenza avevo notato anche un rallentamento nella comparsa
dei caratteri a schermo rispetto alla pressione dei tasti ho cominciato
a nutrire perplessità sulla solidità del mio ubuntu...
Mi è venuto in mente un vecchio comando DOS che mostrava le connessioni
di rete attive in tempo reale ed ho provato ad eseguirlo:
netstat -a >net1.txt
Questo è l'output generato sul file net1.txt:

In questo caso sembra che ci siano diverse connessioni in attesa
(TIME_WAIT)
in altri casi nella colonna "foreign address" ho diversi indirizzi IP in
stato ESTABLISHED risalenti a stati esteri.
Se eseguo "firestarter" l'output diventa molto più breve:

Qualcuno sa dirmi se è tutto normale o se invece potrebbe essere

Grazie e ciao!
