 The most obvious possibility seems to be 'maxusers 0'

No.

This just means to autoconfigure a value according to the amount of
memory present at configure time.

Re: -STABLE was stable for long time (Re: FreeBSD: Server or Desktop OS?)

2002-11-17 Thread Thomas Seck
* Marc G. Fournier ([EMAIL PROTECTED]):

 What's to track?  Nothing happens on that branch ... I just CVSup'd
 RELEASE, followed by RELENG_4_7 and the only changes were pretty much
 related to the latest BIND vulnerabilities ...

The security branches are fortunately a very slowly moving target for
which you can develop and maintain *your* *own* patches.

What stops you from doing just this?

What keeps you from applying Matt Dillons VM patches to RELENG_4_7?

What keeps you from merging new features from -STABLE into your private
RELENG-branch?

You have chosen to maintain systems which stretch FreeBSD to its limits
and uncover bugs lurking in the code. This is great. But you cannot do
so on the one hand and refuse to face the administrative work on the
other hand. This does not work. You have the freedom to maintain your
own release with all the patches and fixes you need. Why don't you do
it? Instead you waste your time with complaining (and you waste my time
because I have to read it and think about the replies I am going to
send)?

As for the eroding stability: this is partly true, in my opinion because
-CURRENT and -STABLE's codebases have diverted to a great extent. There
were so many new CURRENT-only features implemented in the last few
months (SMPng, KSE, GCC update, GEOM, ...) which caused more or less
grief and instability for a long time. My guess is, that due to this no
one using -CURRENT had time to test features which were to be MFC'ed
extensively. And due to the ongoing instability of -CURRENT there were
probably not enough non-developer users with -CURRENT systems for
testing, so probably most things MFC'ed in the last few months got their
first round of thorough testing by a wide user base just after the MFC.
Anyone remember the ata(4) trouble?

I do not know whether the above was true when RELENG_3 was -STABLE; I
use FreeBSD only since 4.0. But I think that it could not have been that
bad, since I found 4.0 useable. As it seems 5.0 will be shipped with
big red warning signs attached :)

 Purely security vulnerabilities ... no 'critical patches' ... I would
 consider most anything related to the VM subsystem to be 'critical', at
 the very least ...

Please discuss this with the security officer.

 But, what you miss in here is that picking and choosing which patches to
 use is useless, as it doesn't take into consideration the interactions of
 other patches you don't apply ... or the reliance of future patches that
 would be useful on those patches you don't apply ... if I wanted to
 pick-n-choose patches, I'd run Linux ... I choose to run FreeBSD because
 its an Operating System, not a Kernel with a 101 different distributions

Basically, you want others to do the developing, testing and patching
and keep the complaining part for yourself.

 Please correct me if I'm wrong but I don't think the splx patch does
 anything to help people with broken CD-ROM drives.

You are right. It fixes a coding mistake which panicked boxes using TQ.
All other issues are still present.

[/etc/crontab vs. crontab -u root]

 ??? More visible?  New people to the system can never find that file.  
 Heck, I'm always forgetting where it is.  It wouldn't be so bad if
 it just weren't so inconsistent.

See cron(8), second paragraph.

 So, what I'm actually doing is:
 
 1. Set up NAT to route between my ethernet card and tun0
 2. Set up the firewall rules via PPP

Ugh.

Simply let ppp(8) take care of NAT, do the firewalling with ipfw(8) and
you're done. Close to trivial.

Re: Strange SCSI error message

2001-06-06 Thread Thomas Seck

On Jun 06 2001, Karsten W. Rohrbach wrote:

 there were some questions a while ago concerning the freebsd vs linux
 scenario where a freebsd fails with SCB timeouts while a linux runs
 along with apparently no problems at all. the quick answer for this
 particular behaviour in freebsd is, that the io subsystem is designed to
 put more load onto the scsi devices than the implementation of other
 os'es io subsystems. so, basically, what happens is, that you only see
 the timeouts under freebsd, of course, since it arbits the scsi bus more
 often, and with more data in the same period of time compared to other
 implementations.

Yes, this might well be the problem. What bothers me is that these 
errors only appeared when the box had been _really_ idle for hours.

 terminate correctly, symmetric terminators, active, for u160. use good
 cables, no vobis crap ;-) 

Vobis? Hey! (Note: Vobis is a chain of computer shops in Germany 
notorious for selling *really* crappy HW for about 15 years now)

 i use amphenol cables for external links and
 gr-kabel (german distributor) for internal wiring. this solved most of
 my scsi problems with u160.

Well, I hope I never have to see these problems again, cross fingers.

Thank you for your response and

Good work, Bruce.

I noticed one minor problem when I tried to build them: I had

DOC_LANG=en_US.ISO_8859-1 de_DE.ISO_8859-1
RELNOTES_LANG=en_US.ISO_8859-1

in my /etc/make.conf but making the docs via 

# cd /usr/src/release/doc
# make DOC_PREFIX=/usr/doc all 

failed because it was trying to build the reldocs for de_DE.ISO_8859-1 
too, apparently using DOC_LANG instead of RELNOTES_LANG.

I have a PR open (kern/26880, unexpected busfree errors), cocerning
