Compiled OK, and operating nicely on CentOS 6.6, both 32/64 bit. Really appreciate the UpdateHostkeys feature! One issue I noticed, the screen output gets garbled if the user has been "asked" to "Accept" the new hostkeys. Looks like the screen output is missing the CR's, and only LF's get presented.
