Does anyone have an opinion about the third issue in Appendix E?
Basically, news servers use either port 119 (NNTP) or port 433 (NNSP);
news clients use either port 119 (NNTP) or 563 (NNTP/TLS). The use of
119/433 ports is described in Sections 3.4.1 and 3.4.2 of RFC 3977:
The official TCP port for the NNTP service is 119. However, if a
host wishes to offer separate servers for transit and reading
clients, port 433 SHOULD be used for the transit server and 119 for
the reading server.
As strict TLS over a dedicated port is the current TLS best practice to
use, what should we do for transit servers? We currently have no
NNSP/TLS port. Do you believe we should ask to register a new port
NNSP/TLS?
Otherwise, what should we recommend? (My fear is that adoption and use
of that new port by news servers will be slow, or even will never be
happening...)
