That really would would break things wouldn't it. Why is it that so often people just start wholesale deleting things without checking appropriate places. apropos mail should point out to the observant eye several things to check and reach the desired results without breaking things. Reading docs pointed out /usr/sbin/sendmail is a link to /usr/sbin/mailwrapper. The /etc/mail/mailer.conf describes how to use this so that you tell the systemexactly what programs to run when you call sendmail. Take a look at that and it should fix the problems. IOW using the name 'sendmail' can invoke other programs instead of the real sendmail. On top of that if you really don't want sendmail at all, then in /etc/make.conf put in the NO_SENDMAIL=NO directive. Man make.conf will clue you in on that. The system really is quite configurable with the tools built in without having to rip out directories wholesale and then wonder what you have to put back to make it work again. Use the docs Luke.

Its probably a part of Intel's and your motherboard spec actually, but generally SMP is only supported on CPUs of the same family and model. At least recently, Intel says that all steppings of a particular model are SMP-interoperable, but not of differing models. > model : 3 > model name : Pentium II (Klamath) > stepping: 4 vs.. > model : 5 > model name : Pentium II (Deschutes) > stepping: 2 -- Doug White| FreeBSD: The Power to Serve [EMAIL PROTECTED] | www.FreeBSD.org To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-stable" in the body of the message
Re: HEADS UP: Package compression format changed
I am an enthusiastic FreeBSD newbie, just smart enough to search for a mailing list like this one. Would it be possible to make an exception to the new .tbz format package policy for pkg_add itself (i.e. provide it in .tgz format)? I suggest this in the hope that a painless and simple upgrade could be performed using something like: pkg_add -r pkg_add This is assuming that there are no other technical obstacles. If this notion is nogo then what is the simplest alternative? Please pardon my ignorance. I see that this thread subsided on a note of resolution, but I'm daunted by the implications for the time being. Not for long I hope.

Don't know whether this value is really used. Returning to the original question, I'd never seen on our servers mbuf usage more that 2 times nmbclusters usage, so in every instance where I've explicitly set nmbclusters, I'd also set mbufs as 2*mnbclusters (this may slightly decrease kernel memory reservations comparing to setting nmbclusters only) This applies mainly to TCP servers, where most data flow is described as "Most packets are of maximum MTU".

An mbuf is a fixed length structure which contains network data. An mbuf cluster is associated with an area of memory which is used for storing more data than you can fit in a single mbuf. According the D&I 4.4 an mbuf is 128 bytes and (not all of this is available for data storage), an mbuf cluster varies in size, but defaults to 1024 bytes (but according to the book this may be different depending on CPU architecture). > I've wondered precisely this; perhaps one specifically relates to the > network?

interpreting netstat -m output
Hi, I'm working with a box that is apparently running out of mbufs: looutput: mbuf allocation failed looutput: mbuf allocation failed All mbuf clusters exhausted, please see tuning(7). Looking at netstat -m, I get the following: 144/9472/26624 mbufs in use (current/peak/max): 134 mbufs allocated to data 10 mbufs allocated to packet headers 94/6656/6656 mbuf clusters in use (current/peak/max) 15680 Kbytes allocated to network (78% of mb_map in use) 95798 requests for memory denied 102 requests for memory delayed 0 calls to protocol drain routines What is the difference between the "mbufs in use" line and the "mbuf clusters in use" line? The clusters are showing that a max was exceeded, but not the mbufs line at top. Looking at tuning(7) and reading up in the archives, it looks like I do need to bump up nmbclusters in loader.conf, and possibly bump down the tcp socket send/recv space. Can anyone clarify the netstat output for me?

RE: Updating world with least downtime
I recently rebuilt the world on my pII 400 system, and here is how long it took me. /usr/bin/time make installworld 266.34 real74.23 user43.33 sys /usr/bin/time make installkernel 26.11 real 6.89 user 2.38 sys So it took about 4.8 minutes to install the files, given average consumer grade disks. Compiling is more cpu dependant, but the install portion is more a function of disk-io. Mergemaster is obviously dependent on how quickly it takes the operator to run that command. But if you budget 10 - 15 minutes, it should be good enough.
