It turns out that rand(3c) in even recent Solaris versions returns values in the range 0..32767 only. I suppose this is part of Sun's rather extreme paranoia about backwards compatibility with programs written before the flood.
The specific thing that brought this to my attention was that, when using the -j option to dnssec-signzone, I couldn't get jitter of more than a few hours however large I set the option. isc_random_jitter in lib/isc/random.c has return (max - rand() % jitter); and now it is obvious why that was. There are probably other bad things happening elsewhere in BIND and its associated utilities. Sun provided the drand48(3c) routines as an alternative to rand(3c), even back in the SunOS 4.x days, and they have a better spec. I was about to write a version of lib/isc/random.c using lrand48() instead of rand(), but thought I would ask whether anyone has done the same thing already. Also, a suggestion to ISC that they use lrand48() on Solaris, in the same way as they use arc4random() if that is available. -- Chris Thompson Email: c...@cam.ac.uk _______________________________________________ bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
