** Tags added: apport-collected natty

** Description changed:

  I got a machine which has eight public ip addresses bound to eth0,
  eth0:0, eth0:1, eth0:2 etc.
  
  If i try to bind an address using -b for outgoing connections it just
  fails to do so but creates the connection without any warning or
  message:
  
  ssh -v -o UsePrivilegedPort=no -o BindAddress=x.x.x.131 other-host.com
  or
  ssh -v -b x.x.x.131 other-host.com
