There was a _reason_ the prior poster asked about seeing your code.
The information you provided is not adequate/sufficient for anyone to
have any chance of helping you.  Informationn that -is- necessary was
therefore requested.  

What you "don't use" is irrelevant to solving the problem. 

To be any help one must figure out what you _did_ do -- which =indirectly= 
calls flockfile().

Your code calls "something" in 'libc'  that calls flockfile().

You "don't know" what that something in your code is.  Other eyes _might_
recognize it, -if- they saw what you were doing.

Here is how to find out what does that calling, yourself.
 1) recompile all the components of 'myprog' with the '-g' compiler option.
 2) start 'script', so that you have a complete log of the debugger session.
 3) load the debugger with 'myprog' as the program to be debugged.
 4) set a breakpoinnt in the 'flockfile' function
 5) 'run' the program
 6) when it stops at flockfile() entry. use 'where' to see a stack trace.
 7) 'display' each of the arguments to flockfile().
 9) go 'up' to the calling code.
 9) repeat steps 7 and 8 util you reach 'your' code.
10) now 'continue' the program.  If it immediately segfaults, this was the
offending call.  Otherwise, the program will stop aggain at another
flockfile() invocation. repeat from step 7 -until- you get the segfault.

If, from that debugger session, you still don't see anything wrong, post
the log of the debugger session.

There is a *remote* possibility that the program will run properly under
the debugger, while it crashes when run directly.  This has been known 
to happen when a program _uses_ a variable before initializing it.

*IF* that happens, you will have to modify 'myprog' to add diagnostic
output before and after each identified point (above) in your code that
indirectly invokes flockfile() to find which is failing.  

In _that_ event, you =will= have to post the 'relevant' source-code from
'myprog', with the failing statement identified.

This is a different class of machines. They are made to be repaired and they 
are very large.

I have had a Fujitsu P2120 which died after a lightning strike. So, I 
disassembled it. The machine is so small that they have had to use all tricks 
get it this small.

The most interesting thing for me was the affect of damage to this machine. It 
got hit by something like a sledge hammer when it was not with me. This bend 
the magnesia cover but did not cause any internal damage. The material is very 
brittle but no metal dust fell into the machine.

The P2120 uses even a special glue to connect the graphics chip with the hear 
sink. The heat sink cools also the CPU. There is no way on this machine to take 
the heat sink off and later back, if this glue is not at hand.

Re: netif starting late after upgrade to FreeBSD 9.0 from 8

Thanks I stumbled upon netwait already. The only problem I have now is PF.
The rules of course include network interfaces but lo0 doesn't seem to be
up yet.

The upgrade following /usr/src/UPDATING was without any problems.

The only issue I have is that there seems to be a race condition for

require it, resulting in the following problems :

1. pf rules not being loaded as it can't find network interfaces

I suspect that it may be a file was not installed/updated after

How do I troubleshoot this? I've tried to manually change REQUIRES for

Any pointers would be much appreciated to possible solutions would be

If using DHCP, use SYNCDHCP instead.  For static IP addresses, see

No. Real men don't eat quiche. And real programmers don't
use Pascal. Also, stupidity must be punished (even if it's
me who is stupid), and it _will_ be done. Always and
repeatedly. You only learn the hard way. :-)

Exactly, and you're not depending on buying expensive software
that might not cover your particular problem case. The documentation
of all the "inner elements" of FreeBSD are present, and you can
learn (in worst case) everything yourself to solve the problem.
As other skilled persons have estimated and experienced the
need for professional tools, they've created them. Many of the
free tools can cope with the expensive ones designed for proprietary
platforms. The "default action" of UNIX ("if in doubt, do nothing
and let the master decide") can save your data, whereas the
habit of "repairing" things can make things worse (which includes
automounting r/w, fiddling with the FS or other nonsense that
destroys data).

TSK had _good_ documentation locally installed. I don't really
understand what's the idea behind moving it to a location that
can only be accessed via Internet connection. Really, it's not
_that_ much (hundreds of MB) that you couldn't leave it in the
install... sad, just sad...

Again, programs like portdowngrade help a lot. :-)

Yes, it also uses a 'heatpipe' to move the heat away from the CPU to a heatsink

Start small. The model mentioned above has had a cover on the back giving 
access to the CPU. The next bet is the keyboard. The rest needs some mechanical 
knowledge.

I doubt this is related, but using -lpthread is wrong. use -pthread

"Both"?  I'm aware of at least three (FreeBSD, 4.3BSD, and 4.4BSD) that
are probably within the realm of what you're talking about (learning
about the workings of a BSD Unix system), all of which seem a little
redundant -- just different editions of the same book, from the look of
it.  What do you mean by "both" of McKusick's books?

I think there's an answer book for at least one of those, too.  Do you
perhaps mean the main book and the answer book?  Do you mean to include
the general-purpose "open source" book as one of the books (Open Sources:
Voices from the Open Source Revolution)?

If you have a decent ebook reader, I recommend just getting on the
O'Reilly mailing list for its periodic announcements of ebook discount
deals and picking up an occasional good book from those deals.  It's easy
to get far more excellent books than you have time to read that way, for
really good prices.  In fact, O'Reilly has a 50% off deal for a few
ebooks about C programming right now:

http://shop.oreilly.com/category/deals/c-programming.do

O'Reilly's ebook deals are about the only way I've found to get good
technical books from a major publisher in digital formats at a reasonable
price, considering most of the publishing world still thinks it's okay to
charge more for ebooks than for hardcopy books for some asinine reason.

O'Reilly is, in fact, pretty far ahead of competitors on its handling of
ebooks.  For instance, if you have a hardcopy O'Reilly book, you can
register it by ISBN with O'Reilly, then get an ebook copy of it for about
five bucks.  By contrast, The Pragmatic Bookshelf (which produces very
high quality books as well) at *best* gives you the opportunity to get a
hardcopy book plus a PDF book at the same time for about 150% of the
cover price of the hardcopy alone, *only* if you buy them together from
the Pragmatic website itself, and if you only have the ebook or the
hardcopy book you have no way to get a discount on the other; you have to
pay full price.  Pragmatic does offer ebooks at slightly lower price than
hardcopy, which is at least better than the "standard" industry practice
for science fiction, but it's a ridiculous price for a bundle of bits in
a digital file.

O'Reilly offers some kind of discount on hardcopies for people who have
the ebooks, too, I think.  I'm not sure -- I've never taken advantage of
that discount, because I only started collecting ebook copies of O'Reilly
books after getting an e-ink reader, which I find every bit as good for
many (though not all) reading purposes as a physical dead tree format
book.  Your mileage may vary, I suppose.

Reading symbols from /libexec/ld-elf.so.1...done.

I don't use flockfile () directly in my program.


I use -lpthread.

Same program runs without any issue on FreeBSD 8.1.


Any idea what's going on?

Building kernel outside of /usr/src (with an unprivileged user)

[Matthias Petermann]

Hello,

while trying to build a patched CURRENT src on a STABLE FreeBSD 9 I was 
wondering if it would be possible to have the source directory (src) in 
a different place from /usr (e.g. in /home/myuser/src) where it can be 
built with an unprivileged user and without interference with the STABLE 
sources in /usr/src.


Does anyone have an idea how to achieve this?

Kind regards,
Matthias

netif starting late after upgrade to FreeBSD 9.0 from 8

[Khairil Yusof]

I've just upgraded in place from FreeBSD 8 to FreeBSD 9.0.

The upgrade following /usr/src/UPDATING was without any problems.

The only issue I have is that there seems to be a race condition for
bootup scripts in which netif can start later than devices that
require it, resulting in the following problems :

1. pf rules not being loaded as it can't find network interfaces
defined such as lo0
2. named not starting

I suspect that it may be a file was not installed/updated after
mergemaster -i but, when I check /etc/rc.d/netif and pf the REQUIRES
line is the same as that in /usr/src

How do I troubleshoot this? I've tried to manually change REQUIRES for
pf for example to LOGIN, but it doesn't have any effect.

Any pointers would be much appreciated to possible solutions would be
much appreciated.

Not a big issue. Make sure you can remember which parts belong where.
Make photos if it helps you, or draw some notes. If possible, find
the service manual of the device and use it as orientation. But I
think such kind of documentation is no longer part of the "end user
book present". :-)

I've been lucky exploring that my "new" Lenovo Thinkpad T61p can be
easily disassembled up to the CPU region and the cooling units
without trouble, and with _standard_ tools, and you don't need
to eviscerate _all_ the bowels of the device in order to make
your way to that component.

Yeah I didn't know either until it fried my CPU. Many laptop heatsinks
use "heat pipes":

http://en.wikipedia.org/wiki/Heat_pipe

The hole will probably be too little to notice but in my case I
noticed some oxidation/stain around the hole which gave it away.

Except buying (good) books, you can also search for

Hi

While updating 9.0-RELEASE to 9-STABLE today mergemaster wanted to put in a 
new hosts file that does not contain the localhost entry.

I don know why this changed, but I left the localhost entry in my hosts file.

I didn't even know they put fluid heatsinks in laptop.
I thought this was something from IBM cutting edge power6
chips.

So I might need to pull the laptop apart..
I'm just not sure I could put it back

Probably not. I had a laptop with similar symptom when I was compiling
stuff. I took it apart, cleaned it and thought that maybe these log
messages were normal under stress. The CPU eventually fried and only
then I took a real close look and the heatsink had a very tiny little

sight. These liquid (or gel?) filled heatsinks are basically useless
if the liquid escapes or evaporates so it will usually only show when

laptop very hot and noisy

[Anton Shterenlikht]

I run 10-current on Compaq 6715s.
It's very hot and noisy. If I boot
in verbose mode, I get lots of:

acpi_tz0: _AC2: temperature 92.0 >= setpoint 50.0
acpi_tz0: _AC1: temperature 92.0 >= setpoint 60.0
acpi_tz0: _AC3: temperature 92.0 >= setpoint 40.0
acpi_tz0: _AC2: temperature 92.0 >= setpoint 50.0
acpi_tz0: _AC1: temperature 92.0 >= setpoint 60.0

at the console.

I guess it's telling me that the CPU is too hot?

Is that normal, e.g. under "make -j4 buildworld"?

Thanks

Limiting closed port RST response

[Arthur Chance]

Every once in a while the nightly periodic security checks tell me I've 
got a kernel message


Limiting closed port RST response from N to 200 packets/sec

where N > 200. The problem is that it doesn't say which port was 
involved. Is there any way to find that out so I can try tracking down 
the problem? AFAICT tcpdump doesn't have a way saying "closed ports on 
this machine" as a filter.

So, what is the variable 'port' initialized to?  It should be a const
char* with the name of a network service found in /etc/services or else
the string representation of a port number in decimal.

Failing that, this is almost certainly a configuration snafu on your
9.0-STABLE box.

Does this machine have an entry for localhost in /etc/hosts ? Can it
resolve localhost via the DNS? Or through any other means such as NIS or
LDAP?

What does:

% getent hosts localhost

return?

If that fails, sanity check /etc/nsswitch.conf and /etc/resolv.conf

Cheers,

Matthew

Has anybody out there taken the BSDA certification exams?

[herbert langhans]

Hi List,
on Saturday the 5th of May there is the Central-European BSD day in
Vienna. They also give the chance to make the BSDA certification
exams.

I went through the 'BSD Associate Exam Objectives' to get some idea
the questions. But I still wonder, how NetBSD users get away with the
style of questions and solutions asked. Its some years ago that I used
FreeBSD and I have for sure forgotten lots of details or never ran into
certain commands/solutions since changing to NetBSD.

Has any of you taken the exams? Has somebody told you about the exams? 
By the Exam Objectives I think its not that easy to pass ...

Cheers
herb langhans

localhost not recognised in getaddrinfo(3) in FreeBSD 9.0-STABLE

[Unga]

Hi all

Following code fragment works in FreeBSD 8.1-RELEASE, but not in FreeBSD 
9.0-STABLE:

error = getaddrinfo("localhost", port, &hints, &res0);
 if (error)
    {
 fprintf(stderr,"getaddrinfo failed - %s\n", gai_strerror(error));
 exit(1);
    }

It complains: getaddrinfo failed - hostname nor servname provided, or not known

Any idea why?

Best regards
Unga

Thanks!. I will try creating different filesytems to further my

An informed critic would have recognized that the 'lack of knowledge' issue,
and the 'nonsense questions' were two -entirely- different matters. 

One who lacks knowledge of system fundamentals and asks questions _about_
_the_fundammentals_ that they do not understand is not subject to 
criticizm -- they are educatable.

Those who make grossly false-to-fact assumptions about the behavior of those 
fundamentals, and extrapolate wildly from those erroneous assumptions
cannot be engaged in rational conversation -without- hauling them back
to the initial erroneous assumptions, and correcting those errors.  And,
when that is done, it invaliates everything extrapolated from the false
premise.

Those who continue to extrapolate wildly in such manner cannot be helped.

It was also established that the OP's descriptions were woefully incomplete
and unreliable.  A second disk was involved.  'dangerously dedicated' or
otherwise?  partitioning?  slices? label type?  There is indirect indication
'everything of interest' was on a single slice, but that is only an inference.
There's no indication of where _in_the_filesystem_ on the slice that the 
jails '/' directories were located, or by what names they were known to the
system outside the jail.  The 'pattern' of the names, and placement in the 
hierarchy _is_ likely of some significance. As is (a) ownership, (b) 
permissions, and (c) 'flags', of (1) the original 'containing' directory,
(b) the external view of the jail '/' directories in that directory, and
(c) 'where they ended up'.  It is likely that that 'external view' (pre-
problem) of the jail '/'s does not exist -- unless one had historical data 
from before the problem.  "Everything" was running in jails.  Except for
things that weren't.

For any constructive analysis of "what happened", one needed to capture *all*
the bits in the directory (itself) where the jails ended up -- a directory
'listing', e.g. 'ls' (regardless of options), is not sufficient -- and the 
same for the directory where they 'should have been', plus a copy of the 
slice's complete inode table -- i.e., from _all_ the cylinder groups.  Then 
one would examine the 'last modified' timestamp on the directory where the 
jails were found, and -then- the timestamps on the jail directories 
themselves. 

Among other things, this data allows one to establish whether or not the
jail directories were ever _really_ where one thought they were, or whether
they just 'appeared' to be there, e.g. due to nullfs, or a 'link'.  And an 
'initial estimate' of -when- it may have happened.  (if 'malice' is involved,
or certain kinds of backup/restore activities, the timestamps _may_ not be 
accurate, but they are a 'best available' guess.)

Capturing -all- the data from the 'where they were' directory, allows one
to examine the 'deleted' entries -- where one _should_ find entries for
the jails, and 'last accessed' timestamps which put a lower bound on when
the 'move' occured.

When the 'apparently impossible' happens, it is *VERY*OFTEN* the case that
'reality' is *NOT* what someone 'knows' it is.  No matter how 'obvious' it
is, one has to =verify=.  

It is also _FAR_ 'easier to believe' that (especially) a nullfs mount (or,
less likely, a hard link) disappeared, than directories actually got moved.
The move may well have happened, but one must 'positively' eliminate the 
'more plausible' alternatives first.  Things that would 'give the appearance'
of what was reported, but from -very- different causations.

Of course, to capture this kind of information, one have to know "what's 
where" in the filesystem metadata, and have means to capture it _without_ 
changing any of that data.  And _that_ means that you have to have a fair
understanding of the mechanics of how the filesystem works.  Which rapidly
leads into gory details of how the O/S does disk I/O, and the various
performance optimizations (and trade-offs) employed.

Reading _both_ of McKusick's  "Design of .." books, and the 'Unix System 
Admininstration Handbook', by Nemeth, et al.  is a good _start_.

Having a bunch of the books from O'Reilley & Assoc. (),
especially for 'standard' tools that you need to get the most out of, is
also highly recommended.  

Disclaimer:  I know a lot of the authors of those books, persoally.
