Hej NG Kan jeg via ping finde ud af hvilke porte der er lukket hhv. ud og ind? (Hvad er den "rigtige" kommando til formålet?)
Ping viser ikke portstatus. Fra man ping: Ping uses the ICMP protocol's mandatory ECHO_REQUEST datagram to elicit an ICMP ECHO_RESPONSE from a host or gateway. ECHO_REQUEST datagrams (``pings'') have an IP and ICMP header, followed by a ``struct timeval'' and then an arbitrary number of ``pad'' bytes used to fill out the packet. Nmap viser portstatus; se 'man nmap'. Eks.: $ nmap localhost Starting Nmap 4.20 ( http://insecure.org ) at 2008-04-16 13:52 UTC Interesting ports on localhost (127.0.0.1): Not shown: 1692 closed ports PORT STATE SERVICE 80/tcp open http 443/tcp open https 631/tcp open ipp 6000/tcp open X11 10000/tcp open snet-sensor-mgmt Nmap finished: 1 IP address (1 host up) scanned in 0.590 seconds -- Med venlig hilsen Jørgen Heesche mailto:heesche@xxxxxxxxxxx
