- that is not what i thought of. we know exactly, where our trnasceivers
- are. but we have about 600 machines on our ethernet. sometimes there are
- new machines, sometimes boards are changed.
- we can not walk along the cable to look after every transceiver.
-
- if the new machine uses IP, then we can find out all about the new
- machine, but if it is a different protocol, then we can find out (by looking
- at the packets) what sort of machine/ethernet board and what protcol is
- used.
- we might be able to write a programm, which will ask the new machines
- after their name. but we will have to know about something like a
- name binding protocol for the used protocol. unfortunately most of the
- protocols are not very well documentated.
-
- any ideas?
