- * SSH Protocol 1.5 aka New Channel Protocol
- * Thanks to Martina, Axel and everyone who left Erlangen, leaving me bored.
- * Written by Markus Friedl in October 1999
- *
- * Protocol versions 1.3 and 1.5 differ in the handshake protocol used for the
- * tear down of channels:
- *
- * 1.3: strict request-ack-protocol:
- * CLOSE ->
- * <- CLOSE_CONFIRM
- *
- * 1.5: uses variations of:
- * IEOF ->
- * <- OCLOSE
- * <- IEOF
- * OCLOSE ->
- * i.e. both sides have to close the channel
- *
- * See the debugging output from 'ssh -v' and 'sshd -d' of
- * ssh-1.2.27 as an example.
