Hello programmers, hello maintainers!
Like most of the old smtp servers (e.g. sendmail), ssh servers makes it
pretty easy for an attacker to get the name of the software and its version:
> badboy:~ > telnet niceboy 22
> Trying a.b.c.d...
> Connected to localhost.
> Escape character is '^]'.
> SSH-2.0-OpenSSH_3.6.1p2
> ^]
> telnet> close
> Connection closed.
I am not a friend of "security through obscurity", but I think each
administrator should have the choice...
