Ok. Block a specific port is really easy... But the problem is: kazaa tries to use the port 1214, but if it's blocked, he use other ports... And if i block all other, it uses the port 80, that i can't block, cause my users need web..... I'm googling for the answer too... If i find something, i put it on the list too. -----Mensagem original----- De: fedora-list-bounces@xxxxxxxxxx [mailto:fedora-list-bounces@xxxxxxxxxx] Em nome de jludwig Enviada em: quarta-feira, 5 de maio de 2004 16:40 Para: For users of Fedora Core releases Assunto: Re: How to block Kazaa; NIS authentication On Wed, 2004-05-05 at 15:03, Markku Kolkka wrote: > Artur Sampaio kirjoitti viestissään (lähetysaika keskiviikko, 5. > toukokuuta 2004 21:12): > > 1) The W2k user insist in use kazaa, that was prohibited from > > enterprise's owner.....I wish to block the port of kazaa on the > > server (iptables??). someone knows how? > > http://www.linuxjournal.com/article.php?sid=6945 > > -- > Markku Kolkka > markku.kolkka@xxxxxx Blocking a port with iptables is rather trivial. A couple of examples. $IPTABLES -A INPUT -p udp --sport 23 -s 0/0 -j LOG --log-prefix \ "Incorrect DNS source" $IPTABLES -A INPUT -i lo --sport 631 -j ACCEPT $IPTABLES -A FORWARD -o $EXTIF -p tcp --dport 137 -j DROP $IPTABLES -A FORWARD -o $EXTIF -p tcp --dport 138 -j DROP $IPTABLES -A FORWARD -o $EXTIF -p tcp --dport 139 -j DROP See http://www.linuxguruz.com/iptables/ for more and better information -- jludwig <wralphie@xxxxxxxxxxx> -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: http://www.redhat.com/mailman/listinfo/fedora-list
