Having this patch active rngd complains: rngd[1435]: rngd 2-unofficial-mt.13 starting up... rngd[1435]: block failed FIPS test: 0x1f rngd[1435]: block failed FIPS test: 0x1f ... rngd[1435]: stats: entropy added to kernel pool: 0 rngd[1435]: stats: FIPS 140-2 successes: 0 rngd[1435]: stats: FIPS 140-2 failures: 10 It doesn't do this without the patch. The only available rng was via, I did blacklist the others just to be sure. regards Mario --=20 The social dynamics of the net are a direct consequence of the fact that nobody has yet developed a Remote Strangulation Protocol. -- Larry Wall --rwEMma7ioTxnRzrJ Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) iQEVAwUBTSMQbRS+e2HeSPbpAQLQxggAgp/V6UfheJo2VYVPQgh5aVw7U/9wpiyh wL4cVWDXAqKlf4iTA2ArHpwd/l5idgiEAfhMo733Wb7mG31un8hFQ5n0zDHh7nmt qt+ArghURZyLxNyU7hsm58gv0j77sI0daOkUDBzIfXI8V2efKgZ7KV1vRyWQ/L// Q7qnPJliWGrXMYx4+ebAft/pf78On+hQvrNrPN3qq/W4m9rTsg2sbI5MWLU8FFJw Pu4LId1sPaIxO3NBrrydeBkdoLqvM9oBCcjMfMbgdAc9Ip/EZphOwYPEEwSBFzm6 KrnNqsDhdf4NUslWm1aX1w0bmfo1/T7dp2l0/RwgpXDQvRO53jUyPA== =P0Ex -----END PGP SIGNATURE----- --rwEMma7ioTxnRzrJ--
