  -----------
  Fix error checking for socket connections

- IO::Socket::UNIX->new should never die, therefore...
- $@ is always undef when the eval exits, so...
- use $! instead

  Log Message:
  -----------
  Improve error messages

- Add "p0f" to error output to aide in debugging
- Remove some no-ops which called only '... if $@', in a context
  where $@ would never be set, or never be meaningful.
