I can SSH to my Raspberry Pi = and BeagleBone Black just fine from another RELENG_9 FreeBSD system, and = from a Debian Wheezy system. The failure mode for those that don't work = is the same as reported above---a signal 6 on the server side. Also, = this hasn't always been the case, but I can't recall a revision number = when the problem began. Cheers, Paul.
