ICMP Destination Unreachable (Port Unreachable)

[Tony Wong <tonyw () stanford edu>]

I dont understand why I keep getting these "ICMP Destination Unreachable
(Port Unreachable)" in my alerts. the source is from a pc to an apache web
server. Running


I ran ethereal on the pc when doing an ftp and this is usually when it
happens.

I get an ICMP Destination Unreachable when doing an ftp. I can ftp in ok
no problems but why these ICMP Destination Unreachable messages?

Thanks
