Re: openssh update broke connectivity

OK, shellworld was the wrong host, but the information still applies.  Even 
generating new keys might not solve the problem.  You probably have to edit 
ssh_config to allow the weaker cyphers or downgrade your ssh client.  I 
would suggest asking them to upgrade their sshd or to generate stronger host 
keys.  The change log clearly explains this in much more detail.

No, you should be able to use password authentication, so you should not use 
plain, unsecure ftp except in an emergency.  That's assuming they allow 
password authentication which is the default in most cases.  You can still 
use rsync or ssh to connect with a regular password.  Since it won't connect 
and isn't asking you for a password, this makes me think the problem is with 
their sshd using weaker cyphers and there probably isn't much you can do 
about it except write to them and explain the situation.  For now, I would 
suggest going back to an older ssh client.
