On: FreeBSD deprecates all r-cmds (rcp, rlogin, etc.)

In the unlikely event that it matters, scp and I believe ssh have a flag to use no encryption.

Not that I'm aware of (at least not in openssh; maybe the commercial ssh has such a "feature"). Do you happen to know what that flag is?

I'm pretty sure it doesn't have one either, and that's by design. It seems very dangerous to have such an option. The best you can if encryption limits you is to use a faster cypher such as arcfour (RC4).

It actually reminded me of this old OpenSSH poster: http://openbsd.appli.se/images/poster2.jpg

IIRC the "++" on the RSH tombstone is a reference to a config directive that would open RSH access to anybody from anywhere, effectively giving you a very simple and rather inconspicuous way to "trojan" any rsh install. With SSH the best you can do is install a public key in ~/.ssh/authorized_keys, but it's not quite as convenient as simply adding a "++" in a file when nobody's looking.

See for instance https://www.mkssoftware.com/docs/man4/rhosts.4.asp

Strange; it appears that you're right. There are patches for `-c none`, but nothing official. Perhaps I'm misremembering sibling's suggestion of using a faster cipher.
