weird save-entropy behaviour
Greetings. Yesterday, i noticed a very weird behaviour on my computer (which is running 8.0-RC3 btw. The shells were not responding and the load was insane, and constantly going up. At the time i managed to lock myself out, the load was 84 and growing (i have a screenshot if anyone is interested). That happened last night. Today, the computer was ok and i managed to ssh into it. The root account was spammed with two types of cron mails. half of them said: mv: /var/db/entropy/saved-entropy.2: No such file or directory and the other half said: override r operator/operator for /var/db/entropy/saved-entropy.2? (y/n [n]) not overwritten So i know that it's the save-entropy cron job, but i doubt that was supposed to happen, and i have never touched that directory. Anyone has an idea? ps. this has happened before, and i had to go to the place the computer is at and reset it. (the tty's did not respond either) -- Real programmers don't document.

# id operator

As for the orer part, why did it stop, i really have no clue. All the messages
arrived at root's mailbox at 5:57, tho the date in them said that they were
sent at 5:50.
It's really strange because I was locked out from the computer at 2:29, so
it's not something I did. and there's nothing that cron runs at that time.
by the way:
the mails that i got were not only about /var/db/entropy/saved-entropy.2, but
/var/db/entropy/saved-entropy.{1,2,3,4,5,6,8} as well

It is used to safely seed the random number generator, I believe.

It has to be on the root partition as it's used in the early stage of the boot before any other partitions are mounted, but like like I said there are other entropy files that are applied a little later as a boot, and on most machines enough entropy will be generated from the disk interrupts to suffice anyway. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

I tailored and compiled the kernel and upgraded the system by the usual commands: make buildword boot mergemaster -p make installworld mergemaster boot The locale is Italian and the system speaks Italian, for instance mc. Not it happens that when launching 010.pgsql start, apache.sh start, etc. they all start issuing the following warning --: not found Besides, after upgrading to 6, I go on receiving each 11 minutes the following email Date: Wed, 25 Jan 2006 18:00:00 +0100 (CET) From: [EMAIL PROTECTED] (Cron Daemon) To: [EMAIL PROTECTED] Subject: Cron [EMAIL PROTECTED] /usr/libexec/save-entropy X-Cron-Env: SHELL=/bin/sh X-Cron-Env: PATH=/etc:/bin:/sbin:/usr/bin:/usr/sbin X-Cron-Env: HOME=/ X-Cron- Env: LOGNAME=operator X-Cron-Env: USER=operator --: not found /var/log/messages doesn't say anything related to this.

Re: Problems with locale entropy (what's that?)
vittorio [EMAIL PROTECTED] writes: On a (mainly) postgresql pentium 4 server at office I upgraded freebsd 5.4 to 6 by means of a CD with the standard ISO downloaded from ftp.freebsd.org (I can't use any alternative means becuase of the tight rules of security of our network). I tailored and compiled the kernel and upgraded the system by the usual commands: make buildword boot mergemaster -p make installworld mergemaster boot So what you're saying is that you did a source upgrade rather than a binary upgrade, and that you got the sources from the CD? If so, and you did a buildworld but no buildkernel/installkernel? That means you're still running a 5.4 kernel. Perhaps you mis-typed your usual commands? [After all, there is a typo in them, so you obviously didn't cut and paste from what you actually did. The locale is Italian and the system speaks Italian, for instance mc.

This is, to put it plainly, wrong :-) ZAxisMapping belongs in an xorg.conf/XF86config file. It looks like someone who didn't really understand what they were doing ran sysinstall and specified this with the internal quotes as a parameter to moused. Garbage in, garbage out I'm afraid.

You don't get any console output whatsoever to give us a clue what's failing? No log files? Nothing more than Entropy Device is Blocking? modified files to give various IRQ's for entropy generation. I have read and searched (and had search engine failures), trying to find out more information on the problem and how to resolve it. No luck thus far. I suspect the reason you can't find information on the problem is that it isn't a problem for the rest of us. It sounds like you did something unusual. Did you use the standard install, or did you try to do something special? Which version of FreeBSD are you using? Can anyone give me the pointer to the piece of the fscking manual that tells me how to configure this beast to save a seed at shutdown and then use that seed file at startup instead of just dying and leaving me with a It already does that. At least, for me it does, right out of the box. Or CD drive, or whatever I got it out of. Is there a file named /entropy on your system? What version of FreeBSD are you using? system that is half-booted, or failing that simple request, how to work preseedrandom into the system startup so that it will happen BEFORE entropy is required? In addition to some addition context regarding when the error message appears, and which version of FreeBSD you are using, the contents of /etc/rc.conf and any other files you changed might be informative.

Problems with /usr/libexec/save-entropy
Ok, I'm an idiot! I MUST have done something to my system yesterday. It's been running fine, and around 3:00pm yesterday, I started receiving emails from Cron /usr/local/save-entropy saying: *User: not found I've tried everything, and looking into everything. I've checked my master.passwd and group (compared 'em to /usr/src/etc). I've checked crontab (/etc/crontab), and root's crontab (empty). I've also compared to another 5.1 (Release) box, and everhthing is the same. Could someone point me in the right direction? I'm running: 5.1 Current. I even did another update, build world, kernel and merge this morning, all to no avail! The line in my crontab is: */11 * * * * operator /usr/libexec/save-entropy And when I try to run it from the command line I get: /etc# /usr/libexec/save-entropy *User: not found Any/all help would be appreciated.

5.1 Hangs on boot (Entropy harvesting)SOLVED
Hi everybody. I think I found what caused the problem with my FreeBSD 5.1 desktop hanging at Entropy harvesting. Rebuilt with GENERIC kernel and everything went smooth. In my CUSTOM kernel I had enabled IPFILTER and IPFIREWALL, but no rules for IPFILTER. When I removed the lines concerning ipfilter, the problem went away. Why ? I don't know :-) It was not configured with default to block.

Well, for starters, this is the wrong list. You are supposed to ask question about 5.x on -current. You are also supposed to subscribe to the commit list and etc. If you don't want to do this, then 5.1 release may not be the appropriate choice of OS for you.

Why we have it ? etc etc The term entropy is often used (in rough analogy to its technical meaning in thermodynamics) in computer systems to describe the amount of randomness available to random-number functionality. The entropy is the mean information per symbol. The higher the entropy, the more random the language is. It can be shown that the entropy is maximum when all the symbols in the alphabet have the same probability 1/n, where n is the number of symbols in the alphabet. In that case, the entropy has a value of -n*log2(n). Also, in that case the alphabet is trully random. What to read depends on why you need to know about it, but you could always refer to some manual pages, particularly rndcontrol(8). If you want a more solid background, get an introductory book in information/coding theory. But don't try it if you don't know calculus, probability and algebra.

Re: entropy
From: http://people.freebsd.org/~bmah/relnotes/5.0-RELEASE/relnotes-i386.html The random(4) device has been rewritten to use the Yarrow algorithm. It harvests entropy from a variety of interrupt sources, including the console devices, Ethernet and point-to-point network interfaces, and mass-storage devices. Entropy from the random(4) device is now periodically saved to files in /var/db/entropy, as well as at shutdown time. The semantics of /dev/random have changed; it never blocks waiting for entropy bits but generates a stream of pseudo-random data and now behaves exactly as /dev/urandom. - aW Entropy is a tendency towards disorder in the universe, exemplified by things LIKE SOME FREAKIN' CLUELESS GIT POSTING A TOTALLY OFF-TOPIC SCIENCE MESSAGE TO A COMPUTER OS LIST!!!
