There's a *0 bug in hfaxd that shows up when the user logs in without
a password, and the etc/hosts file requires one.
Here's the fix:

  		if (++loginAttempts >= maxLoginAttempts) {
  		    reply(421, "Login incorrect (closing connection).");
  		    logNotice("Repeated SNPP login failures for user %s from %s [%s]"

      if (checkUser(loginID)) {
  	if (passwd != "") {

  		if (++loginAttempts >= maxLoginAttempts) {
  		    reply(421, "Login incorrect (closing connection).");
  		    logNotice("Repeated SNPP login failures for user %s from %s [%s]"
