Hallo Linux-Friends, I scanned my own box (my own dynamic IP) when I was online with: netcat -v -z 80.131.118.62 1-65535 p5083763E.dip.t-dialin.net [80.131.118.62] 33352 (?) open p5083763E.dip.t-dialin.net [80.131.118.62] 32769 (filenet-rpc) open p5083763E.dip.t-dialin.net [80.131.118.62] 32768 (filenet-tms) open p5083763E.dip.t-dialin.net [80.131.118.62] 6000 (?) open p5083763E.dip.t-dialin.net [80.131.118.62] 631 (ipp) open p5083763E.dip.t-dialin.net [80.131.118.62] 111 (sunrpc) open p5083763E.dip.t-dialin.net [80.131.118.62] 22 (ssh) open And now I am afraid not be alone on my box !? What could I do now to close the unwanted ports? I took a fresh new /etc/services from www.iana.org/assignments on my system. rose:~ # grep '6000' /etc/services .... x11 6000-6063/tcp X Window System x11 6000-6063/udp X Window System ... rose:~ # But why the port 6000 is not shown by netcat? only a ? Although it is in my /etc/services! Is this port necessary for a local machine, when I dont want X-forwarding? for ipp I have to look how? to deactivate this in cups? What can i do, to find out what is behind 33352 (?) open 32769 (filenet-rpc) open 32768 (filenet-tms) open ____________________________________ The same thing when I was yesterday offline: 46837 (?) open 32769 (filenet-rpc) open 32768 (filenet-tms) open 6000 (x11) open 631 (ipp) open 111 (sunrpc) open 80 (http) open 22 (ssh) open Best Regards and thank you in advance from Mick ; ~ {o} under shock Now I do logout and go to sleep. -- # MfG Michael Maldener + Das beste Linux ist die Pluralitaet aller Linuxica ;)
