ssh into NetBSD 10.0 from older systems

[Robert Nestor <rnestor%mac.com@localhost>]

I installed the latest version of NetBSD 10.0 BETA and tried to ssh into it from an older system, in my case Mac OS X running 9.5 (Mavericks).  I got an error “no hostkey  alg”.  Never saw anything like this when I was running 9.2, and I was able to ssh into the new system from another system running 10.0.

After some research and experimentation I discovered that I needed to add this line to the NetBSD /etc/ssh/sshd_config file:

    HostKeyAlgorithms +ssh-rsa,ssh-dss

I mention it here in case someone else stumbles into the problem.  Might be nice to add this to the default sshd_config file with a comment that it might be needed to allow older systems to connect.
