first, you are talking about boot loaders or boot managers; its different from 
MBR witch means master boot record

When you say "FreeBSD can identify windows and load it", you have wrong the 
concept of FreeBSD can identify, because FreeBSD its not loaded yet, a program 
called BootEasy its the one identifying windows (an others OS) and display F1: 
Windows etc..

http://www.freebsd.org/doc/en_US.ISO8859-1/books/faq/disks.html#BOOTEASY-
LOADER

Look in ports for boot loaders (manager)

http://www.freebsd.org/cgi/ports.cgi?query=boot+loader&stype=text&sektion=all
http://www.freebsd.org/cgi/ports.cgi?query=boot+manager&stype=text&sektion=all

Its a good idea to read Chapter 9 (Disks, File Systems, and Boot Loaders) of 
FAQ

http://www.freebsd.org/doc/en_US.ISO8859-1/books/faq/disks.html

This is a classic scenario.  Some burst of traffic causes your apache to
spawn more child processes than will all fit in RAM at one time.
Consequently, the system starts to swap.  Swapping kills performance.
This slows everything down so much that there are always requests
waiting for apache to process, so apache will never find any idle
children to kill off.  Result misery.

The answer is to limit the number of child processes apache will spawn.
Decide how much of your available RAM you can devote to Apache.  Look at
top(1) to find the maximum size apache processes grow to.  The ratio of
those two sizes is the maximum number of apache processes your system
can support.

Limiting the total number of apache processes sounds counter-intuitive.
What happens when you get sufficient traffic that apache maxes out?  Web
queries will generally be queued up until there's an apache child free
to handle them.  Generally that will take from a few 10s of milliseconds
on up -- although if you're regularly getting into a state where your
webserver takes seconds to answer, then it's time to get more beefy
hardware.

Cheers,

Re: Make gtk widgets use a larger font

I'm not sure if it will still work, but in the past,
you could create ~/.gtkrc and override settings as
you liked.

style "font_1"
{
font= "-b&h-lucida-medium-r-normal-*-12-*-*-*-p-*-iso8859-15"
}

class   "*" style "font_1"
widget  "*" style "font_1"

Then replace "iso8859-15" with the font encoding you
need, and of course "12" with any other font size
that fits your needs. In order to construct the font
determination string based on a visual impression and
attribute selection from lists, you can use the

% xfontsel

program.

Attention: Untested.

you replaced the "wireless router".   Presumably this is also the wireless
'Access point', to which the laptop connects.

What are the chances that it doesn't support WPA,  but *ONLY* supports WPA2?
May need to tweak the ifconfig params, and/or the supplicant 'key_mgmt' type.

Kernel panic on power button

I just pressed the power button on my desktop computer - it seemed
like it was attempting to do an ACPI suspend instead of a power down
like I expected - but I'm not sure.

Either way:
When It got close to the end

I got

Hi,

I have to use FreeBSD 6.0 because the network stack I will test is only based 
on 6.0. BTW, I am using internal networking mode now, these two VMs could 
communicate with each other now. This mode seems could satisfy my needs, 
because my VMs only need to communicate with each other, not with the outside 
world.
Thank you so much for help.

Did you bump kern.ipc.shmall?  The one you bumped is the maximum size of
a single shared memory request, shmall is the maximum amount of shared
memory for the entire system.  They both have to be increased.  To make
it more confusing, shmall is in pages, not bytes, so you have to divide
by pagesize (sysctl hw.pagesize).

Re: What is loading my server so much?

[Laszlo Nagy]

First off, you have 24G of RAM available and PostgreSQL only seems to
have access to 400M of it.  Bump shared_buffers up to 2 or 3 G at least,
and bump up work_mem to at least a few hundred meg, and
maintenance_work_mem up to at 1/2G or so.


All right. Here is what I did. I setup a new shmmax value this way:

sysctl kern.ipc.shmmax=8589934592

It is 8G.  (By the way I also have kern.ipc.shm_use_phys: 1 ) Then I 
have changed shared_mem to 1024MB in postgresql.conf.

Then I tried to start postgresql I got this message in the log:

Dec  9 17:53:59 shopzeus postgres[27247]: [1-4] The PostgreSQL 
documentation contains more information about shared memory configuration.

(currently 203).
Dec  9 17:55:52 shopzeus postgres[27328]: [1-4] The PostgreSQL

I do not understand.

Doc says these:

"max_connections cost ~ 400 bytes of shared memory slot, plus lock space 
(see max_locks_per_transaction)."


Even if I had max_connections = 5000, total shared memory required would 
be way below shmmax=8G.


What am I missing here?

according to man 1 whois you can specify alternative hosts to query as
well as alternative databases.  specifically i think the -h switch

Re: What is loading my server so much?

[Laszlo Nagy]

Step 1, get them to define "server" and "too slow":

If you log in and do shell ops, is the system slow to respond?  Based on
what you've reported, I'd be willing to bet that shell ops are pretty
responsive.  I can't be 100% sure without more information, but I'm
willing to be that what your users are complaining about is your web
application being slow.  Since you don't say what that application is,
I can only provide general advice.
Shell response is fast. The application may be slow, but we should see 
why (high CPU load or high I/O?)

I'm guessing that PostgreSQL is the bottleneck.  I'm going to first make
a few general suggestions, then provide suggestions on how to isolate the
problem more specifically.

First off, you have 24G of RAM available and PostgreSQL only seems to
have access to 400M of it.  Bump shared_buffers up to 2 or 3 G at least,
and bump up work_mem to at least a few hundred meg, and
maintenance_work_mem up to at 1/2G or so.
Good point. Changed shared_buffers to 4G, work_mem to 512M and 
maintenance_work_mem to 2G

If the top and gstat outputs are typical, it looks like PostgreSQL is
doing mostly writes, but is not significantly blocked on writes.  It looks
like individual PostgreSQL processes are simply taking a long time to do
their work.

What's in your PostgreSQL log files?  If there's nothing, then bump up
the logging information in your postgresql.conf.  I particularly like
log_min_duration_statement at 500 ... any query that takes longer than
1/2 second to execute is suspect in the types applications I work with
most frequently.
Thanks for that hint also. We have some programs making huge queries 
(once in a day or so) so I set this to 3000 for now.

If your application is developed in-house, I'd be willing to bet a paycheck
that there are LOTS of indexes missing and that PostgreSQL is doing lots
of seq scans where it could run lots faster if it had indexes.

Check also your autovacuum settings and ensure that tables are not bloating
out of control due to insufficient vacuuming.  You may have to vacuum full/
reindex the entire database to get things back under control, which can take
a long time if it's badly bloated.
Well, we have tables with 5M+ rows (table size over 4G) and we have 500+ 
tables. This is probably something that is out of scope - probably you 
cannot help with that without knowing the structure of the database and 
how it is used, and it would take a long time to understand. But anyway, 
if there is a problem with the database (not having indexes), we see 
heavy I/O or CPU load of the postgresql processes right? I mean, if the 
bottleneck is postgresql, then we should be able to see it at the OS level.

Your application may also be suffering from lock contention if there are
lots of table locks used.  Looking at the pg_locks table while things are
slow can quickly identify if this is the case, and looking at
pg_stat_activity in conjunction with that table will usually narrow down
the problem pretty quickly.
We do not issue "lock" statements directly, but we use database 
transactions. We have a tool for checking the state of those. Most of 
the time, only a few open database transactions are opened, and usually 
we don't have locks that are not granted.

Finally, if you find that PostgreSQL is the bottleneck and you can't
narrow it down enough to fix, join the PostgreSQL general questions
mailing list and ask for help with the same level of detail you did
here.  You'll find that they're an equally helpful community.

I'll do that, but first let me test the new settings.

Yes, thank you very much for you help.

This may/may not mean anything. Some days ago I got a brief mail
from  reminding me to "re-up".  I quit them months ago when they
wanted to slam me for some absurb amount-- $153.00--to be my
secondary.  

I deleted their email; then in October my ~/Maildir got wiped.
(I-done -it[?])  FWIW, I had an Amazona glitch around 16:00
localtime yesterday.  Amazon couldn't verify my Visa card.  I
retried hours later and the DDoS seems to have resolved itself.

Bridged networking makes the guest behave like another physical installation
with respect to networking.  If your network doesn't have a DHCP server then
for DHCP to work one is required.  You don't need DHCP for networking
however, you could simply assign static addresses.

In NAT mode, VirtualBox provides it's internal DHCP server.

Hi,

I am sorry I don't know which page you refer to... I am confusing now cause 
first, I don't know which mode could be best for my needs. What I need is two 
VMs on a real machine, these two VMs could communicate with each other. It 
seems bridged mode is suitable here. But there is no network access for bridged 
mode. 

BTW, when I use NAT mode, two VMs get the same IP address, and they could not 
get to each other.

Thanks,

Runaway ProFTP?

[Ryan Coleman]

Dear list,

Has anyone else had experience with ProFTP 1.3.3a running away with processes? 
I installed it about 2 months ago with a new server build and over the course 
of the last three weeks I've had to forcibly kill, wait and restart the service 
every one-to-three days and sucking up between 20% and 80% of my system 
resources.

I've attempted to change the logging in hopes to track down what is causing the 
problems but I have not been successful. Additionally it won't connect after a 
restart through Filezilla but using Terminal on my MBP it will connect in the 
CLI.

It's not the end of the world (for me) but it is for my staff when they have to 
upload large numbers of photos.

Thanks,
Ryan

I'll take a stab in the dark as to the cause, but not to whom is
responsible. This looks like an erroneous DNS Injection. An attempt to
inject false/misleading dns entries into [or before] a valid dns server
serves a reply. This is usually contributed to a bad admin who improperly
secured his/her DNS server or a malicious admin with the intent to wreak
havoc.

It would appear that if the port is already installed, passing '-o' will
only update the source location (origin) to prevent breakage in the future.

Could you clarify in regards to what you want sendmail to actually use
/etc/host for?

If your intent is to re-map where mail destined for a given host/domain goes
- (ie override DNS MX records) - then /etc/hosts is not going to do what you
want. Depending on where you intend to redirect to, you'll need either
mailer table, access table entries or to configure your local sendmail to
receive for that domain to accomplish that. You might try reading further
at:

http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/mail-using.html

Specifically in regards to email and DNS relationships.

It would appear that Ubuntu has not correctly installed the bridging
adapter. Did you check out the links I provided on setting up a bridging
device on Ubuntu w/ vBox? They worked for me, I set up an Ubuntu VM and in
the VM setup a test VM of vBox to boot fbsd (8.1 in my case).

NOTE: I do not recoomend setting up a VM within a VM, I did it strictly as a
test to boot and get network access. Which it did.

you can use natd as well in rc.conf

  natd_enable="YES"
  natd_interface="rl1"
  natd_flags="-dynamic"

then as root in the base system

  kldload ipdivert
  natd -n rl1

or whatever your interface is

I'm seeing lookup problems for several big domains, plus as an

I've been looking into this, although my intention was to make the fonts
smaller.  I have yet to be successful.  I think the answer should lie in
modifying your gtk theme file (.gtkrc-2.0 for GTK 2).

2) Install the new port manually:

autoconf and automake

[Steven Friedrich]

I'm having trouble with the latest advice in ports/UPDATING:

20101208:
  AFFECTS: autotools
  AUTHOR: autoto...@freebsd.org

  Another stage in the autotools cleanup that reduces tree churn whilst
  updating components, a number of ports have now moved to non-versioned
  locations since there is now only the concept of legacy and current
  versions.

  # portmaster -o devel/autoconf devel/autoconf268
  # portmaster -o devel/automake devel/automake111
  # portmaster -o devel/libtool devel/libtool22
  # portmaster -o devel/libltdl devel/libltdl22

  substitute 'portupgrade' for 'portmaster' accordingly if that's your
  your upgrade tool of choice.

If I invoke portupgrade -o devel/autoconf devel/autoconf268
portupgrade doesn't appear to do anything:

portupgrade -o devel/autoconf devel/autoconf268
--->  Session started at: Thu, 09 Dec 2010 13:52:08 -0500   
   
** None has been installed or upgraded.
--->  Saving the results to '/root/done'
--->  Session ended at: Thu, 09 Dec 2010 13:52:08 -0500 (consumed 00:00:00)

And pkg_info says there's still an old version of autoconf:

pkg_info|grep autoconf
autoconf-2.13.000227_6 Automatically configure source code on many Un*x 
platforms  
autoconf-2.68   Automatically configure source code on many Un*x platforms 
autoconf-wrapper-20101119 Wrapper script for GNU autoconf


Can anyone help me?  I'm thinking that I'm trying to upgrade all ports that 
depend on autoconf-2.13.000227_6 to depend on autoconf268.

Hi, 

I do not configure a DHCP server. When my FreeBSD 6.0 is booting, there are 
several DHCPDISCOVERY messages, finally it shows no DHCPOFFER received. Do I 
need to configure a DHCP server myself? If I need a DHCP server? Where it 
should be? Now I only have one test machine, Ubuntu as the host OS, two VMs 
(both are FreeBSD 6.0) on this machine. I want this two VMs communicate with 
each other. 

Just go back to the DHCP stuff, when I use NAT mode, the guest OS FreeBSD 6.0 
could get DHCPOFFER successfully. Who is the DHCP server then?

When running dhclien em0, the results are similar to the DHCPDISCOVER results 
during booting. No DHCPOFFERS received. 


Thanks,
W.W.

simple NAT for jails

[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 ?

I encrypt my data with gbde, it fetches the passphrase from another

Did you try putting this in the "/etc/make.conf" file:

WITH_OPENSSL_PORT=yes

Then try doing an R&R on the ports and see what transpires. By the way,
the port version of openssl is 1.0.0c, so you might want to update your
ports tree before attempting to rebuild the afflicted ports. Also,
check the updating file. You will need to rebuild a few files before
continuing on with your project.

First curiosity I would have is these 7 zombies. Which processes are they 
and how did they get into that state? Might give you a thread to pull on for 
unraveling. Also, there is some degree of discrepancy present wrt to 6 
thousand processes with only 7 running and 623 asleep. I suspect this is 
just top not getting it right. But it also looks like a forkbomb.

Step 1, get them to define "server" and "too slow":

If you log in and do shell ops, is the system slow to respond?  Based on
what you've reported, I'd be willing to bet that shell ops are pretty
responsive.  I can't be 100% sure without more information, but I'm
willing to be that what your users are complaining about is your web
application being slow.  Since you don't say what that application is,
I can only provide general advice.

I'm guessing that PostgreSQL is the bottleneck.  I'm going to first make
a few general suggestions, then provide suggestions on how to isolate the
problem more specifically.

First off, you have 24G of RAM available and PostgreSQL only seems to
have access to 400M of it.  Bump shared_buffers up to 2 or 3 G at least,
and bump up work_mem to at least a few hundred meg, and
maintenance_work_mem up to at 1/2G or so.

If the top and gstat outputs are typical, it looks like PostgreSQL is
doing mostly writes, but is not significantly blocked on writes.  It looks
like individual PostgreSQL processes are simply taking a long time to do
their work.

What's in your PostgreSQL log files?  If there's nothing, then bump up
the logging information in your postgresql.conf.  I particularly like
log_min_duration_statement at 500 ... any query that takes longer than
1/2 second to execute is suspect in the types applications I work with
most frequently.

If your application is developed in-house, I'd be willing to bet a paycheck
that there are LOTS of indexes missing and that PostgreSQL is doing lots
of seq scans where it could run lots faster if it had indexes.

Check also your autovacuum settings and ensure that tables are not bloating
out of control due to insufficient vacuuming.  You may have to vacuum full/
reindex the entire database to get things back under control, which can take
a long time if it's badly bloated.

Your application may also be suffering from lock contention if there are
lots of table locks used.  Looking at the pg_locks table while things are
slow can quickly identify if this is the case, and looking at
pg_stat_activity in conjunction with that table will usually narrow down
the problem pretty quickly.

Finally, if you find that PostgreSQL is the bottleneck and you can't
narrow it down enough to fix, join the PostgreSQL general questions
mailing list and ask for help with the same level of detail you did
here.  You'll find that they're an equally helpful community.

Good luck.  Hope this helps.

I'm going to weigh in now. :)

If you want to install FreeBSD using X with a pretty GUI, you can do that 
today. Use a PC-BSD install DVD. There is a radio button in the installer to 
make it install plain FreeBSD. 

pc-sysinstall is in HEAD now, and it is completely functional. It's been doing 
PC-BSD and FreeBSD installs for a long time now. 

The way it works is it does an install based on a config file, so really the 
work on the front end is building a tool that will build a config file.

The real issue is that you really want a volume and disk layout "wizard" of 
sorts. The ability to take some disks, maybe make a gmirror, or a ZFS RAIDZ, or 
even use glabel on a single disk, then layout some filesystems on that, then do 
the install. 

It turns out that this is really simple to do in a web app, and not quite so 
simple to do in curses. You want things like constraining choices based on 
previous input. For instance you can't make a RAID-Z from two devices. 

As far as floppy based installs and all of that, the last successful install 
via floppy that I can find documented was in the 3.x era, in the 90's. That was 
over 10 years ago. Booting from floppy is pretty rare these days, and I submit 
that a system that has no choice but to boot from floppy isn't going to be able 
to run FreeBSD 9 anyways. My Pentium Pro can't boot anything newer than 4.11, 
and *that* has USB ports. 

Anything with a chance of running FreeBSD 9 can boot

I would love to try that sometime - but right now I have to get this regular
ftp working.

certificate keeps messing it up: http://pastie.org/1358536 - anybody know

Server is running: mailscanner + apache multihost + PHP + postgresql. 
Main load on the server is usually postgresql.


Today something happened. Number of http processes went up to 200. As a 
result, number of connections to database also went up to 200, and the 
web server is now refusing clients with "Cannot connect to database" 
messages (coming from PHP).


This is a typical output from top:

Here is what I don't understand. "last pid" is increasing relatively 
slowly, e.g. there are no hidden processes. Only the first one or two 
processes are showing CPU load > 10%.  The "CPU User%" value is about 
50%. We have lots of free memory. I/O load is almost nothing (see iostat 
below).


However, server load is between 7 and 13! In fact sometimes it is above 
16. And everybody complains that the server is too slow.


How can I find out what is causing the problem?

That PR is invalid/useless. If you want feedback give more.

You have wpa_supplicant.conf?



Yes, this is my wpa_supplicant.conf file:
  network={
  ssid="wifi"
  scan_ssid=1
  bssid=XX:XX:XX:XX:XX:XX
  priority=9
  mode=0
  proto=RSN
  key_mgmt=WPA-PSK
  auth_alg=OPEN
  pairwise=CCMP
  group=CCMP
  psk="x"
}

Just to remind you - ifconfig says that wlan0 is associated with my 
access point.
I'm happy to provide all details needed, just tell me what you need. I'm 
running FreeBSD 8.1-RELEASE with all SA+errata patches. Standard 
dhclient.conf file.

Probably worth noting that the latest version of zfs has encryption built
in. This isnt available to bsd yet, but i guess theres a good chance it will
be in the next few months as a patch. Might take a (big) bit longer to hit
stable though

you could try isc-dhcp31-client or another client as a stop gap until the pr
is resolved
