+config BR2_PACKAGE_DROPBEAR
+	bool "dropbear"
+	default n
+	help
+	  A small SSH 2 server designed for small memory environments.
+
+	  http://matt.ucc.asn.au/dropbear/dropbear.html
+
+config BR2_PACKAGE_DROPBEAR_URANDOM
+	bool "  Use /dev/urandom (low entropy systems only)?"
+	default n
+	depends on BR2_PACKAGE_DROPBEAR
+	help
+	  By default, dropbear uses the much more secure /dev/random.  If you
+	  are using a system lacking usable entropy sources, this could cause
+	  the dropbear ssh daemon to block forever waiting for entropy that
+	  will never arrive.  By making dropbear use /dev/urandom, you can
+	  prevent Dropbear from blocking while waiting on the random device.
+	  This could however significantly reduce the security of your ssh
+	  connections.  Make sure you know what you are doing if you enable
+	  this option -- most people should answer N.
