like GoldEd, not an ordinary email client. Moreover, there is no
out-of-box encryption and strong authentication involved.
- NNCP requires editing of single YAML @ref{Configuration,
+ NNCP requires editing of single Hjson @ref{Configuration,
configuration file}.
-@item News transmission
- SMTP does not know anything about news, NNTP and so forth. Neither
- does NNCP, because they are not used very much nowadays.
-
@item File transmission
SMTP could transfer files only Base64-encoding them -- this is very
inefficient.
gigabytes files are queued in parallel.
@item SMTP integration
- Mail servers like @url{http://www.postfix.org/, Postfix} offers
- documentation and configuration file examples how to use it with
- UUCP. @url{http://www.exim.org/, Exim} and
+ Mail servers like @url{http://www.postfix.org/, Postfix} and
+ @url{http://www.exim.org/, Exim} offers documentation and
+ configuration file examples how to use it with UUCP.
@url{http://www.sendmail.com/sm/open_source/, Sendmail} could be
integrated with UUCP rather easily too. For using NNCP, just replace
UUCP commands with NNCP ones.
UUCP and NNCP does not known nothing about routing. You have to
explicitly tell how to send (what hops to use) packets to each node.
+@cindex PSTN
@item PSTN support
UUCP and FidoNet always have been working with modems out-of-box.
Only many years later they gained support for working over TCP/IP
TCP daemon, but nothing prohibits using of another 8-bit aware
online transport.
+@cindex anonymity
+@cindex Sybil attack
@item Anonymous peers
NNCP and FTN are friend-to-friend networks exclusively. This is very
secure and mitigates many possible man-in-the-middle (MitM) and
@url{https://en.wikipedia.org/wiki/Sybil_attack, Sybil} attacks.
+@cindex sneakernet
+@cindex floppynet
@item Sneakernet friendliness
No one, except NNCP, supports data exchanging via removable storages
likes flash drives, CD-ROMs, tapes and hard drives out-of-box. It
requires more manual work to do so.
