Ooops.  The FreeBSD port I built from is trailing a bit:

spork@tiny[~]$ ssh -V
SSH Version OpenSSH_2.2.0, protocol versions 1.5/2.0.

And:

spork@tiny[~]$ ssh -c des 216.223.x.x
Unknown cipher type 'des'

However it appears newer versions include it, but warn you:

oscar[/var/spool/tftp/ios]# ssh -c des -l foo 216.223.x.x
Warning: use of DES is strongly discouraged due to cryptographic weaknesses
foo@216.223.x.x's password:

Sorry for the noise,

Charles
