- This particular "bug" is in your other host, not timeslave.
-
- The error message means that the host from which timeslave has been
- told to get the time and date does not support the UDP "time"
- protocol. The other host does not do the right thing when it receives
- a UDP packet for port 37. I bet that if you snoop on the wire,
- you'll discover your time serving host is responding with an ICMP
- port unreachable message. (If you don't have a network analyzer, such
- as the SGI product, then `ping -v` on an IRIS can often be used to
- see ICMP messages.)
-
- If your other machine is using a different port number, then the
- "-p" arg. might help.
-
- What are the "many many hosts with no problem" that get time from your
- other machine? Do they use the Internet time service? Or do they use
- something based on "rsh"?
