Bug 30462

	
I updated to 4.4-RC via source; somehow (possibly mergemaster's
run of MAKEDEV; presumably the subject of another PR) all of my
standard devices became mode 600 or worse, so e.g. /dev/random was
not accessible to normal users.  ssh started printing bogus error
messages, e.g.  when trying sshv1:

fenestro% ssh -o"Protocol 1" mango
ssh: no RSA support in libssl and libcrypto.  See ssl(8).
Disabling protocol version 1
ssh: No protocol version available.

This is a pretty misleading error, and it made me spend quite some time
investigating how I could have failed to include RSA support.

The error for protocol version 2 is even worse:

fenestro% ssh -o"Protocol 2" mango
DH_generate_key

A masterpiece of conciseness, while relaying no actual information.

Fix: 

Check for this possibly-common problem (two seperate people in #bsdcode
showed up at the same time with this problem, either that's amazing
syncrhonicity or it's an easy problem to have) in another way and
report the inability to get randomness.
How-To-Repeat: 	

chmod 600 /dev/*random
ssh -o"Protocol 1" somewhere
sso -o"Protocol 2" somewhere
