Re: ssh None cipher
If the purpose of having a none cipher is to have a fast file transfer, then one should be using sysutils/bbcp for that purposes. Uses ssd for authentication, and opens unencrypted channel(s) for the actual data transfer. It's also very fast, can use multiple TCP streams.

I agree. Is there any harm in enabling this by default, but having the None cipher remain disabled in /etc/ssh/sshd_config? That way people wouldn't have it on my default, but wouldn't have to recompile to enable it.

IIRC, upstream openssh refuses to merge the none cipher patches because you shouldn't do that. But I'd vote for having it compiled in and just disabled by default. It will refuse to let you have a shell without encryption, and prints a big fat hairy warning when encryption is disabled. ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to freebsd-current-unsubscr...@freebsd.org
