I'm guessing that it's sending back an ICMP "Port Unreachable" because it received a packet for a port with no listener. It's a perfectly valid thing for the software to do. It's a stupid message, because it just confuses people. >As I post this I've seen at least a half dozen "invalid port" >messages. I have also noted this message (exactly one occurrence) >under NCSA telnet v2.3b14. What's the relationship? I have the same problem when I use the clarkson ni6510-driver. If I instead use the ipx.com packet-driver wich was included with the Racal-Interlan Ni6510 Pc/tcp packet then I doesn't get any errors in the console-window in Winqvt/net. Interesting. I also get these messages with the 3c503 driver. Perhaps there's something wrong with *all* the packet drivers? Or perhaps the message has nothing to do with the packet drivers at all? -- --russ I'm proud to be a humble Quaker.
