Hi misc

For the archives...

Here is a post with info that solves and explain the case if someone else get 
stuck in the problem.

 This problem was actually caused by an updated OpenSSL. I have had 2048 and 
4096 SSH keys that have worked perfect until my last complete 3-9 -stable 
update.

In OpenSSL  the limit is 3kbit for DSA keys and 16k for RSA keys.  These days 
ssh-keygen won't let you generate DSA keys other than 1024 bit ones (which is 
all the FIPS-186-2 spec allows) so if you want larger keys then you should 
use RSA. The thing that actually caused the problem was an openssl update 
earlier (013_openssl2.patch or its equivalent in -stable), but it didn't 
become apparent until sshd was rebuilt with the new openssl.


Thanks you *very* much for the help Darren Tucker!
