The idea is that option negotiation order will allow you to tell if you are talking to a 4.2 or a 4.3 telnet -- in reality, the 4.2 and 4.3 differences are a result of the differences in OOB data handling between the releases. In particular, 4.2 flubbed the urgent packet handling rather badly; so with those systems, you want to not use urgent packets. This should not effect your ability to connect to CMC. Are you sure that you have the BSD box set up correctly in your local domain name services database? If the CMC telnetd can't do a getpeername successfully, it'll probably refuse the connection. This is *a* possible cause of your symtoms, and not *the* only possible cause.
