+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.
