Yeah... getrandom() apparently pings /dev/urandom by default which, as per the getrandom manpage, blocks until it has entropy. Sounds like we've wound up at much the same place: I took some data off of /dev/random, stored it in a file, and am feeding that to /dev/urandom at boot time (and re-seeding the file after five minutes' uptime). Alas (because, you know, deadline), that doesn't seem to be working. Which is really, really annoying. I'm *still* blocking for three-to-five on getrandom(). I guess it's time to cut my losses and start this in a different language. I mean, most of the hard stuff was figuring out *how* to do things, but I admit, my Perl and Python have grown rusty as I've enjoyed my Ruby... -Ken _______________________________________________ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
