Avoid sharing interrupts in FreeBSD under ESXi

[C. L. Martinez]

HI all,

 I have installed a FreeBSD 8.4 vm under an ESXi 5.1 U1 server. All
works ok, except for interrupt usage between mpt and nic interfaces:

root@fbsdtst:~ # vmstat -i
interrupt  total   rate
irq1: atkbd0   6  0
irq6: fdc0 9  0
irq16: em2 mpt2   945924  1
irq17: em3 em6   2124484  4
irq18: em0 em4 em7+  5950584 11
irq19: em1 em5 em8+   2317830055   4499
cpu0: timer206119496400
Total 2532970558   4916

 I have enabled the following options in loader.conf:

hw.pci.enable_msi="0"
hw.pci.enable_msix="0"

 without a result. Is it possible to avoid to share interrupts in
FreeBSD when it is running as a vm? Exists some kernel option to
resolve this (via sysctl or compiling a new kernel)?

Thanks.

Re: FreeBSD maximum password length

[Michael Sierchio]

I know this may seem off-the-wall to some, but I pasted a hashed
password for a user under 9.1 into the /etc/passwd entry for that user
on an 8.3 machine, and auth continues to work properly.  That's nice.

Hmm, looks like it wasn't MFC'd to 9-STABLE before 9.1's release. Well,
at least it's good to know that it's coming.

Perhaps your PR is unnecessary:

One _little_ terminology detail:

I'd say that bruteforce != dictionary. It's bruteforce _or_
dictionary attack instead.

A dictionary attack is more sophisticated because it uses words
from a dictionary, whereas a _real_ bruteforce will stupidly run
through _all_ combinations of the given charsets and length ranges.
It will _eventually_ be successful, even if our planet doesn't
exist anymore at that time. Finite time, far far away. :-)

The precise cipher/hash is almost irrelevant. What's important is the
amount of work needed to evaluate a password in a bruteforce dictionary
attack. MD5 is still OK for password hashing, the problem is an
inadequate number of iterations in our particular implementation. A
similar problem exists with blowfish and arguably all of the rest.

Another problem is that all current schemes are inadvertently optimised
for GPU attack since they run in very little memory.

The bottom line is: don't let anyone steal your password file.

This parameter can be used to the "make installkernel" command,
for example in a workflow like this:

# make buildkernel KERNCONF=TESTKERNEL
# make installkernel KERNCONF=TESTKERNEL KODIR=/boot/testkernel

Plus the corresponding settings in /boot/loader.conf:

kernel="testkernel"
bootfile="/boot/testkernel/kernel"
kernel_options="foo bar blah"

See /boot/defaults/loader.conf for details.

For booting test kernels, you might also find the nextboot command
very helpful; read "man nextboot" for more inspiration.

As you need max syntax checking from OCR, throw it at as many
different basic interpreters/ compilers as you can, & inspect where
each bleats, some error messages may be more & less usefull for
different errors.

A friend of mine wrote a basic decades back, its in /usr/ports/lang/pbasic/

Hi Pol,

If you include logcheck in a cron job (hourly, daily, etc.), the cron
system will send the email with its output.

On closer inspection it looks like the moons in the right spot, but the Sun
is in the wrong spot.  I will take a look and see if there is no error in
the lines that deal with the Sun's Az/El.  I have the original code that
was scanned from a USNO document.  The OCR was rather sloppy.  I will post
the original in a minute and send the link.

Thanks, again

Not sure what the limitations are. I know OpenBSD uses blowfish and I have  
been using that on older FreeBSD servers as a workaround. I think that  
OpenBSD uses a high number of rounds on their blowfish to make brute  
forces more difficult because of how slow it gets.

Hi Chris,

I prepared a new patch that incorporates my fixes, yours and
Michael's.  I found the coredump - multiple missing right parens on
line 1170.  Then I ran into another problem on line 430 and made an
educated guess with the fix.

The new patch is here, and you'll need to apply it to the original
version of the program:
http://people.freebsd.org/~glarkin/diffs/prog.bas.2.diff

Hope that works,
Greg

Here is a patch to apply to your code that gets the program a little
further: http://people.freebsd.org/~glarkin/diffs/prog.bas.diff

There were some "O" characters that should have been "0" instead and
at least a couple of Unicode characters that I removed.

It prints out some results up to the moon illuminance, and then
bwBasic core dumps, but maybe you'll be able to debug from there.

Good luck,

Huzzah!

9.1-RELEASE and higher indeed use sha512 as the new default.

8.4 still using md5 though (and expected to stay that way).

Question…

Is sha512 the highest it goes in our system?

Depends on the hashing algo.

Old crypt(3) stored passwords with a 12-bit (2x Base64 characters; 
[0-9a-zA-Z./]) followed by the hashed cleartext.

This [ancient] format limited password input to 8 characters. With this 
algorithm, input beyond 8 characters was ignored, so the behavior you describe 
is accurate -- with the old DES based one-way hash algorithm (which hasn't been 
default for a vey long time).

The default in FreeBSD is MD5, but you can go to AES256 (Rijndael) if you like, 
or Blowfish, or whatever you like. Each of these has different limitations, but 
will not exhibit the behavior you describe above.

There is no limit to these algorithms, only in the implementations -- that is 
to say that if you implement a read-buffer of 128k, that's the practical limit 
of your applications input (read: these algorithms have no limitations on 
input, however that being stated… no CRC algorithm has a limitation on input).

But be aware…

What makes these algorithms more secure is their larger salts *and* their 
stated rate of collisions.

MD5 is no longer considered secure. It's secure *enough* for most people, but 
if you run a tight ship, any one with a few multiplexed GPUs running a CUDA 
thread against your hash can break it in a matter of a week if not days. The 
benchmark (in my mind) for any cryptographically strong algo is that with 
almost dream-like hardware, it would still be impossible to reverse the one-way 
trapdoor hash in one's-own lifetime.

Of course, achieving that as a human can be hard considering that we rarely (if 
ever) produce strong inputs to the strong algorithms. However, if you want to 
be pedantic about choosing a strong password… you should actually take respite 
in the fact that these algorithms is still like their CRC brethren in that:

Inputs greater than the hash length are cryptographically more secure than 
inputs shorter than the hash length.

I digress…

If I remember well, any password longer than default size is truncated, so 
passwords

a) 'AhN12Njufsn8794432kjfvsnkkJHNDSMNDKh844mNJKnhjhu8u8424'
b) 'AhN12Njufsn8794432kj'

have the same salt hash value and both validate the user.

I need to moderate the input password in my system's user interface. And I
believe i have tested longer passwords than that, about 1000 characters
long, and there was no limitations, via using this command in a /bin/sh
test shell script : "echo PASSWORD | pw user mod USER -h 0".

at least there was no errors reported by *pw*. i did not test the user
myself.. and it somehow seems correct, as the encrypted output string may
be not a function of the input string, based on the method used.

Thank you :)

Is plain-text passwords even a supported behaviour? I didn't think it was.

_PASSWORD_LEN is the defined limit. It's 128 characters by default but
could be changed at compile time. There may be other limits, such as in
various versions of NIS.

I'm not sure I understand what you're doing, so I don't have any real
advice, but I don't see why 128 characters would be that hard to deal
with.

Thank you, Mark, for your helpful answer :)

yes, i am aware of the max username length of 16characters.. I just wanted

Thank you again :)

You can also use this trick to work on youtube directly:

This video use flash player:
http://www.youtube.com/watch?v=M84Y6VXAIaU

This will give you player directly and can skip flash:
http://www.youtube.com/embed/M84Y6VXAIaU

This will download the video:
http://www.youtube.com/v/M84Y6VXAIaU

Not sure how to change format of a video that will be downloaded. You
can also use http://www.offliberty.com to download audio and video
tracks of web clips in mp3/mp4 format :-)
