Re: How to modify SSH2 prompt message?

[Dave Kline <dave@iitedge.com>]

Not that I like security-through-obscurity, but if a cracker runs 
scanssh on me and sees I am running Debian there is that much less to 
figure out.  I can understand the maintainer's point of view, but I 
would rather audit my network SSH installs manually.  So I would be 
interested in removing non-critical SSH banner information.
