OSX definitely has both /dev/random and /dev/urandom, so I suspect their semantics are similar to what I've experienced on Linux systems before. I'm running (on my Mac): $ java -version Java version "1.6.0_29" Java(TM) SE Runtime Environment (build 1.6.0_29-b11-402-11M3527) Java HotSpot(TM) 64-Bit Server VM (build 20.4-b02-402, mixed mode) ... and this is in my java.security file: securerandom.source=file:/dev/urandom # # The entropy gathering device is described as a URL and can also # be specified with the system property "java.security.egd". For example, # -Djava.security.egd=file:/dev/urandom # Specifying this system property will override the securerandom.source # setting. There is no explicit setting for java.security.egd. I've never had a problem restarting my webapps, but I'm not using SSL on my own machine, which is the most likely thing to require a bunch of entropy on startup. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.17 (Darwin) Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk8eywUACgkQ9CaO5/Lv0PBmLQCgq8O1XwpQTZ7z7hVR91PFVNgW qCEAoKRI7vBFqHx3VA+6QcLJThbtY01l =iR5k -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
