lagg with devices that may disappear

2013-01-22 Thread Eitan Adler
I have two USB devices:

run0/wlan0 - a wireless nic
ue0 - a wired nic

In my rc.conf I have these set up to lagg - (note that this is done
from memory and may not be exact):

# ether address also set up here
ifconfig_ue0=up
wlans_ue0=wlan0
ifconfig_wlan0=WPA
cloned_interfaces=lagg0
ifconfig_lagg0=laggproto failover laggport ue0 laggport wlan0 DHCP

This behaves as expected when both devices are plugged in.

However, when either the ue0 or wlan0 device is removed the link goes down.
In addition, if the device is reinserted I need to re-run service
netif start before the link returns.

It would be nice if removing the either nic failed over to the other
one without additional work. Is there a way I can set up these devices
to properly failover and return on device removal and insertion?

Please CC me as I am not subscribed.

Re: absurd I/O perf with ZFS: hangs on zfs-cv)

Good call.  I thought I had already disabled atime updating but it turns out
that some datasets had this property still on.

 With 8 GB of RAM ZFS enables prefetching by default and I assume
 for the git use case it's not too useful and could hurt performance
 by amplifying read operations. The Data Prefetch Efficiency is
 shown by zfs-stats and if it doesn't look too impressive you might
 want to disable prefetching to see if it helps.

I will look at this number - thanks.

 If your repository isn't fresh, you could also try git gc.
 My impression is that the automatic doesn't trigger frequently
 enough for larger repositories like /usr/src.

This isn't git specific. Doing anything remotely I/O related takes forever:

- starting a new shell take over a minute
- opening a file in vim which wasn't opened recently take a few minutes
- etc.

That said, I will be looking closely at the zfs-stats and see if I
notice any patterns.

 Try sysutils/zfs-stats to get a rough idea of how ZFS is using

Anything in particular I should be looking for?

 If you already followed tuning advice from the Internet without

I have done absolutely no tuning.  Is there anything in particular I

This changed a few months ago when ports and doc switched.

As of now:


- SVN is *the* source of truth.

- CVS is exported from svn. It will eventually go away
- git is exported from svn. It will remain as an option for developers
(including myself).

 To obtain the FreeBSD source, you can use CVS, SVN, or Git?  Do all have
 the same level of support?  Are they all up to date?

SVN is *always* up to date.  We try really hard to keep the others up
to date, but fail at times.

 Also, local branching and merging is amazing.

+1 - but one can always use git-svn.

 but the kernel. Ports are not related.


 q) The files in /etc/rc.d are all executable, from my understanding,
 those files will get executed and it is their duty to check the
 variable `rc-script-name_enable' for whether they should start or
 not. Wouldn't it be more efficient to chmod -x or +x them to
 disable/enable?

For a variety of reasons, no. They do more than just check *_enable in
complex cases.

 q) Is there a tool that can test a set of mirrors for connection time
 and speed (for packages and ports)? Analogous to Archlinux's
 rankmirrors?

looks in ports-mgmt/ there is fastestmirrors or something like that. I
ran it once and forgot about it ;)

 q) Is it possible for the pkg_* tools (especially pkg_add -r) to
 display progress?

no.

 q) I noticed in the ports collection that there were some outdated
 packages (skype-2.2, gimp-2.6), should I report that and where? (A
 PR?)

skype is out of date cause the newer ones don't work.
Generally, reporting out of date ports as PRs with patches (or to
po...@freebsd.org without patches might help) is a good thing.

Larger ports tend to be actively maintained. For gimp try asking
gn...@freebsd.org for progress.

 q) Is it possible to have the ports system compile into an mfs (to
 avoid disk access)?

Yes. Set WRKDIRPREFIX in /etc/make.conf to a mfs disk

 q) Is it possible to have the user asked to change their password the
 first time they log in (using an OTP) in a simple way? I looked at
 OPIE but it seems to be much more complex than what I need.

Look at pw -e ?


Hope I helped and didn't disappoint too much :)

 You can try sysctl -ad but most of the systls are either documented in

 It would be a really handy thing if the output of 'sysctl -d' told you

 Does GPLv3 does force programs you compile with gcc to be GPLed?


 As far as I know, the main difference is that the GPLv3 is
 often called a viral license. Software linking against v3
 libraries and so maybe programs compiled by a v3 compiler
 will have - according to the license - to be released as
 v3 too.

 This word: MAYBE is most crucial here.

This is false: http://www.gnu.org/licenses/gcc-exception-faq.html

 i wouldn't be surprised that FreeBSD team would decide to go back to gcc
 soon.

Unlikely. clang is much better on all the other fronts. Even if clang
produces slightly slower code for math heavy code for now we don't
care that much. The kernel does not spend much time in compute heavy
code. :)

 The application themselves are still installed and will keep functioning, you
 just removed the records of their installation. When you later install newer

 This approach does _not_ work well when using portsnap. From
 the portsnap.conf manpage: Note that operating with an incomplete

Note that the issue of incomplete ports trees has nothing to do with

Hard links are not special. You can't tell something is a hard link

Re: find and remove ?

 Thanks, Eitan, but it didn't delete. What did I do wrong?

I would need to see what command you typed :-)
Go to the top directory you start deleting from and type
find . -name _vti_\*

This will print out what it thinks should be deleted. If you don't see
the directories you expect here then please be more specific about
what should be deleted.
If you do see the directories you expect and running the find command
with -delete doesn't work then we could try and debug from that
point.

 The comamnd:

If you do want a logon screen take a look at x11/gdm (gnome) and

tuning a system for a single user

2011-04-01 Thread Eitan Adler
When I look for tuning guides online, or reading tuning(7) I find a
lot of guides for tuning a system for multiple users or for specific
purposes (web servers, file servers, etc)

I am looking for specific tunables that might make the experience of
using FreeBSD better. I found the sysctl kern.maxusers but I'm unsure
how things affects things.  Can I reduce the amount of time, memory,
etc the kernel spends enforcing quota, scheduling, etc?

I don't have anything particular in mind - just want to get a general
set of tunables I might be interested in.

Re: printf() leak?

2011-03-29 Thread Eitan Adler
Hi David,

 It seems printf() always alloc something and does not free it:

What compiler and what optimizations? Most compilers will optimize a
printf without any special formatting into a puts call instead of a
printf call.
For example clang -O3 -fomit-frame-pointer (which I use for clarity
here) outputs this code:

.file   leak.c
...
main:   # @main
# BB#0: # %entry
subl$12, %esp
movl$str, (%esp)
calll   puts
xorl%eax, %eax
addl$12, %esp
ret
.Ltmp0:
...
str:
.asciz   Hi
.size   str, 3
...

 [snip]
 ==67840==         suppressed: 4,096 bytes in 1 blocks

Lets take a look at what valgrind says immediately after this:
==14481== For counts of detected and suppressed errors, rerun with: -v

One of the lines we get is
--14508-- used_suppression:  1 libc puts leak

Which means it is a known issue and has been specially marked as to
avoid being reported by valgrind.

Lets take a look to see where this suppression happens: in
/usr/local/lib/valgrind/default.supp we find
{
   libc puts leak
   Memcheck:Leak
   fun:malloc
   obj:/lib/libc.so.7
   obj:/lib/libc.so.7
   obj:/lib/libc.so.7
   fun:puts
   fun:main
}

After some investigation I was able to find the following commit:
http://p4db.freebsd.org/chv.cgi?CH=168767 which shows when this
suppression was added and by whom.

I trust that if you are interested in the details of why this leak is
detected you have the skills to follow up on this by yourself :-)

Thank you for trying to make FreeBSD better!

Re: can make -j be used for ports?

2011-03-15 Thread Eitan Adler
Is this possible or am I being unreasonable, or both, or not?

This is unsupported, but you are not being unreasonable. This is a
much wanted feature.

 Yes.  Ports which support parallel builds will have MAKE_JOBS_SAFE=yes set in 
 the port Makefile.  It defaults to running -j with 
 MAKE_JOBS_NUMBER=`${SYSCTL} -n kern.smp.cpus`, but you can change that to 
 some other # if you like.

No, this is incorrect. The MAKE_JOBS_NUMBER and MAKE_JOBS_SAFE is used
internally when building a single port. When the OP is asking if he
can manually specify -j on the command line which would end up
building multiple ports in parallel. This can not be done (primarily
because there is no locking done on ports)

Certain utilities can make this process faster. For example portmaster
prefetches as much as it can,

Is CTM still being offered for updating FreeBSD?

2011-02-25 Thread Eitan Adler
http://lists.freebsd.org/pipermail/ctm-src-8/ appears to be empty and
http://lists.freebsd.org/pipermail/ctm-users/2009-December/000226.html
 seems to be the last mention of CTM on any of the related mailing
lists (other than a few people asking if it was down).

So I have a few questions:
1) Is it still being offered and supported as a method of updating
FreeBSD systems?

2) If not can the section in the handbook be removed? I have attached
a patch which removes references to CTM from the handbook. Should it
be applied?

3) Probably the most controversial question - but I'll ask it
nonetheless. If CTM is no longer an option for updating FreeBSD is
there any reason to leave it in base? Is it still being used by a
sufficient number of people to maintain it?

  Why is this question even arising? Surely there are other

I am familiar with it. I just happened to notice that the mailing
lists were empty and therefore I thought the service is not being
used.

In case you did not notice the subject was in question form and points
#2 and #3 both had an if not  clause. Your initial response answered
my question: that CTM is still being offered. and therefore the rest
of the email is moot.

Use pkg_rmleaves (ports) to remove the leaf ports of gnome and keep

better when doing such a massive switch to either a) delete all the

simple NAT for jails

2010-12-09 Thread Eitan Adler
Hi,
I want to throw together some jails for friends to play with. I'm not
terribly concerned about security on this machine. My goal is to do
something like
ezjail create james 10.0.0.1
ezjail create jared 10.0.0.2
ezjail create joe 10.0.0.3
ezjail create idaho 10.0.0.4

I have a single IP address for my computer - so I would need some kind
of nat to allow these jails to access the outside world - and allow
the outside world to access them.

I've looked into pf and I guess I would need something like

nat on nfe0 from 10.0.0.1 to any - $external_ip

is this correct?
Do I need anything in in /etc/pf.conf ?

 some one help me for the same.

        Could you, in your script do something like:

        cd /Path_to_Data_Root
        find . -name *.chk -print -prune -exec rm -rf {} \;
If you really want to delete all the .chk files extension files at a time
find path -name '*.chk' -print -prune -exec rm -rf {} + \;

 As a long term solution, if you wish to clear /tmp every reboot add
 clear_tmp_enable=YES  # Clear /tmp at startup.
 to your /etc/rc.conf


You may also want to consider changing /tmp to be a TMPFS file system

add the line
tmpfs   /tmptmpfs   rw,mode=01777   0   0

to /etc/fstab (and remove any other /tmp lines).

A warning will come saying that it is highly experimental - but I've

Re: Clean up / filesystem

2010-10-10 Thread Eitan Adler
 I also understodd the meaning of /tmp in this way - does not need
 to survive reboot. For things that have a kind of temporary nature,
 but have to survivve a reboot, /var/tmp is usually used.

I did not know that. I aliased /var/tmp to /tmp which is tmpfsed
I'm guessing I should undo that - right?

 So OPEN authmode is broken somehow? Send a problem report if really is.

 If you set wlan0 for manual roaming it will not hang.

 Use 'ifconfig wlan0 list scan' instead.
That worked, thanks.

 Are you sure that you setup is correct?
 For example you can not connect to AP which require RSN authmode
 if you configure wlan0 for OPEN authmode, you also may not
 connect to AP if you are far away, because you are able
 to receive and send doesn't mean AP can see your packets 

 Try changing ucastrate to lower values.


I'm not really sure what ucastrate does - but here it goes:

$ifconfig wlan0 list scan|head -1
xyz 00:23:xx:yy:zz:aa:bb 1 54M -125:-95 102 E HTCAP WME
$ifconfig wlan0 ssid xyz
$dhclient wlan0
... no link ...
$ifconfig wlan0 ucastrate 9
$dhclient wlan0
... no link ...
$ifconfig wlan0 ucastrate 1
$dhclient wlan0
... no link ...

I'm fairly sure that I'm in an area where the signal reaches because
when I was using the ndis driver (on an old install) it worked.
This is a fresh install now.

 Why is INT (beacon interval of AP) 102 ?

Re: ACPI battery issues

2010-10-04 Thread Eitan Adler
 Eitan,

 I've attached the patch - this came from David Naylor on the ACPI list. If I 
 understand what he told me at the time, it doesn't fix the problem entirely - 
 but I can't pretend I understand ACPI. I know it means that on my S10e I no 
 longer get spammed with ACPI errors - and that my battery status and shutdown 
 work properly.

 The patch applies to /usr/src/sys/dev/acpica/acpi_ec.c

 It needs some new entries in /boot/loader.conf to adjust the timeouts and 
 delays - which you can tinker with. The settings given are what works for me 
 - but search the acpi list archives for David's original email:

 debug.acpi.ec.delay=200
 debug.acpi.ec.gpe=1
 debug.acpi.ec.timeout=100

 Hope it helps,



 Peter Harrison.

Thanks for the patch. Unfortunately the hard drive in the laptop in
question broke and I'm waiting for a replacement. I will test it when
I reinstall freeBSD though. Thanks for the patch.

 The Embedded Controller timed out so battery info is unknown / bogus,

It might be the same issue - but I am able to use shutdown -p to shutdown.


 If you're sure you have the latest Lenovo BIOS/EC updates, try posting
 your report above to the freebsd-acpi list, also providing OS version

I'm unsure if I have the latest BIOS, however the vendor's only update

Re: BWN driver error messages

2010-09-08 Thread Eitan Adler
 I'm not familiar with portsnap, so I'll let someone else troublehoot that.
 But I want to mention that the port was added to the tree six months ago...


I checked it out from CVS and installed the port. I'll test the wireless soon.

Re: BWN driver error messages

 As I recall, I had to add this line to loader.conf because it wouldn't
 autoload it:
 if_bwn_load=YES              # Broadcom BCM43xx IEEE 802.11 wireless NICs

 Someone may have fixed it by now.  I was doing this back during the release of
 8.1

I already did $kldload if_bwn  kldload bwn_v4_ucode.ko  kldload

Re: Xorg Problems

2010-08-26 Thread Eitan Adler
 I used make install as I had no way of knowing that additional drivers
 could be selected.  Perhaps that should be an option to the sysinstall
 program when FBSD is initially being installed.


 Yes, people can't guess what are the names of the drivers, it's in my
 opinion a problem for this port.  I Cced the maintainer.

I have a lot on my plate right now so I can't guarantee that I'll
solve this soon.
Would depending on x11-driver/xorg-drivers instead of requiring
VIDEO_DRIVER being set help at all?
I intended this port to be used when you require X11 to up and running
fast without any overhead. That is why things like xset aren't
installed. It is possible to run X11 with the vesa driver even if you
can get better performance with a different driver.

 Hi,
 I'm the maintainer of x11/xorg-minimal. I have not been following this 
 thread.

 Did you have problems with fonts when installing x11/xorg-minimal ?

 --
 Eitan Adler

 Hi Eitan,
 The Xorg.0.log file shows it can't find some expected fonts.  The file
 is at
 http://wonkity.com/~wblock/tmp/Xorg.0.log

These are harmless. X.org will work without them which is why I didn't
depend on them on x11/xorg-minimal

 The actual problem I am having is that startx produces only a completely
 black screen.  Xorg -config xorg.conf.new -retro  produces the expected
 grid and mouse pointer.  A .xinitrc file is supposed to start a window
 manager.
Modern X.org installs don't show a default window manager (so a black
screen is expected). What is the contents of your .xinitrc file?


 Best regards,
 Fred

I have a key which is meant to switch between the built in and an
external monitor. This key is activated by fn-f7. xev does not report
any activity when it is pressed.
How get I run a script when it is pressed? I think this key is
supposed to report some sort of ACPI event.
