KDE e servizi in ascolto

Messaggio da Kenny96 » 2 giugno 2012, 20:38

Periodicamente dò un'occhiata con netstat per controllare che sia tutto a posto, oggi, dopo parecchio che non lo facevo, ho notato che ci sono diverse voci riconducibili a kde che vengono rilevate da netstat. Usano sia il protocollo TCP che UDP.

E' una cosa normale? Come mai in passato non mi risultavano? A quale scopo sono in ascolto verso internet?

Se anche non sapete darmi tutte le risposte, mi interesserebbe comunque capire se si tratta di una situazione normale, che anche altri utilizzatori di kde riscontrano.

A me non da quel problema...
qual'è esattamente il comando che hai lanciato?

@ambro: io ho dato il comando "sudo netstat -pelatun"

@bash: ho usato i tuoi stessi comandi e ho essenzialmente lo stesso elenco...

Ciao Kenny a quanto so alcuni servizi o demoni usano e hanno bisogno di comunicare in locale, dipende tutto da cosa hai installato, se ci fai caso sono tutti indirizzi locali quelli a cui comunica il software e non hanno nessun instradamento verso l'esterno, poi a quanto so, non sono molto esperto di arch, i servizi con indirizzo di destinazione 0.0.0.0:* utilizzano questo indirizzo in locale in caso si abbia bisogno di una successica connessione per l'acquisizione e instradamento. Comunque da quel vedo non c'e` da preoccuparsi. In ogni caso se vuoi avere un costante monitoraggio puoi affidarti ad Etherape, che e` un comodo software che mostra graficamente le connessioni in tempo reale , e consuma poche risorse. Poi se noti eventi strani fai controlli piu` approfonditi. :wink:

EDIT : Dimenticavo comunque ti consiglio di configurare il firewall se vuoi avere un controllo completo, anche se linux in genere ed archlinux non hanno problemi su questo tipo di cose, e` difficile che si avvi un servizio in remoto o instradamento almeno che non lo si abbia avviato volontariamente.... Per delle idee piu` chiare ti cosiglio la lettura di http://www.e-infomax.com/ipmasq/howto-t ... -it-6.html che anche se un po vecchiotto come articolo ha un ampio uso di grafici ed e` molto esplicativo sull'uso del Mascheramento e mostra come il forwarding e il firewall agisce e sopratutto come siano disattivi di defualt se non espressamente attivati!!! Molto piu` importante e` aggiornata la wiki arch a questo indirizzo https://wiki.archlinux.org/index.php/Firewall#iptables . Dove trovi anche la voce netfilter.org che e` una risorsa validissima.
In ultimo il firewall non necessita di grandi configurazioni soprattutto se non disponi di un server. A quanto ho capito hai alice con ip dinamico, non c'e` di che preoccuparsi.
