Re: bzip2split

% Obviously, 'split' won't work for 2 reasons:

 % Each chunk won't have the BZIP2 header


what a problem?

when unpacking you do

cat allfiles|bunzip2





 % 'split' will cut the file inside a bzip2 block, rendering the
 first/last blocks of each file unreadable.

 perl -pi.bak -e 's/OLDSTRING/NEWSTRING/g' file1 file2 fileN

For a single file it's very easy:

perl -ne 'print unless 8..10' filename

will print every line except lines 8, 9 and 10.

The .. or range operator (in scalar context) is a sort of flip-flop. It keeps 
its own state, which is either true or false. When it's false it only 
evaluates its left-hand argument; when it's true it only evaluates its 
right-hand argument; and whenever the argument it's currently looking at 
returns true, the expression changes state.

If the argument is an integer, it's treated as a comparison against the 
current line number, $. ; so the first expression, 8..10, means

($. == 8) .. ($. == 10)

It's false to start with, until ($. == 8) returns true (on line 8); it becomes 
true and remains true until ($. == 10) returns true (on line 10), when it 
becomes false again and remains false until it next sees line number 8.

You can also use more complicated tests in the range operator:

perl -ne 'print unless /START/ .. /END/'

will find each line containing the word START anywhere, and delete from that 
line to the next line containing END (inclusive of both endpoints) - this 
will work for multiple occurrences of START and END in your file.

There are two problems if you string multiple files together on the command 
line: first, if you're using line numbers, the line number doesn't reset 
between files unless you do an explicit close on each file.

The bigger problem is if you have a file in which the second condition doesn't 
occur (a file with only 9 lines in the first example, or a file with a START 
and no corresponding END in the second case): the range operator will stay 
true until it sees the ending condition in the next file, meaning you'll lose 
the first ten lines in the numeric case, or every line from the top of file 
to the first END in the second case.

To get round these two problems, you need to test for eof in the range 
operator, and close each file when it hits eof to reset the line count.

perl -ne 'print unless 8 .. $. == 10 || eof; close ARGV if eof' file[1-n]
perl -ne 'print unless /START/../END/ || eof; close ARGV if eof' file[1-n]

There's some hairy precedence in the first range expression: a useful tip for 
checking that you've got it right (and indeed in general for checking that a 
bit of Perl does what you think it does) is the B::Deparse core module, which 
you call like this:

perl -MO=Deparse,-p -e 'print unless 8 .. $. == 10 || eof'

which outputs

((8 .. (($. == 10) || eof)) or print($_));
-e syntax OK

The ,-p argument to -MO=Deparse tells it to put in parentheses everywhere. If 
you're like me and like to leave them all out, feed your expression to 
Deparse with all the parens in and leave off the ,-p argument: Deparse will 
get rid of all the unnecessary ones:

$ perl -MO=Deparse -e 'print unless (8 .. (($. == 10) or eof))'
print $_ unless 8 .. $. == 10 || eof;
-e syntax OK

Re: Status of hyperthreading in FreeBSD

[Wojciech Puchar]

Atom's HTT is actually pretty good - I saw up to 25% more performance
simply by using multithreading in 7zip's compression benchmark (on
WinXP, though). Of course, OTOH it uses about that much more transistors
on the CPU die so it's not exactly free performance.


really that much? i thought maybe 1-2% (just 2 sets of registers).

it would be better to put 2 much simpler cores in place of this one.

or 100 ARM7 cores ;) (it would fit)

To delete lines matching a R.E. (grep -v effectively):

   perl -ni.bak -e 'm/SOMETHING/ || print;' file1 file2 fileN

To delete lines by number from many files -- eg. exclude lines 3 to 7:

   perl -ni.bak -e 'print unless ( 3 .. 7 ); close ARGV if eof;' \
file1 file2 fileN

The malarkey with 'close ARGV' is necessary because otherwise perl
won't reset the input line number counter ($.) for each new file.
The range expression ( N .. M ) can take matching terms rather than
line numbers, so you can also do things like:

   perl -ni.bak -e 'print unless ( m/FIRST/ .. m/SECOND/ )' \
   file1 file2 fileN

I may try an ordinary ide cd drive setup as a slave.
On an older system with and IDE drive set as master I had the same

Is /etc/pam.d/su present and does it contain the line:

If so, the /etc/pam.d/system should contain:

account requiredpam_login_access.so
account requiredpam_unix.so

If this is all ok, I suggest rebuilding pam with OPENPAM_DEBUG defined, so 
that you can see where things go wrong.
Just out of curiousity, if you install something like mysql or squid, those 
users should be inaccessable for the same reason, cause I don't see anything 
wrong with the svn user itself.

How can I link two separate internal networks to two separate external networks

[Geoff Roberts]

Hi,

I have a FreeBSD 7.0 box with pf.

I have two internal networks (intnet0 and intnet1) and two internal networks 
(extnet0 and extnet1).

extnet0 and extnet1 are two different gateways to the internet.

I only have one physical internal (int0) and one physical external (ext0) 
interface.

Traffic from intnet0 needs to go out on extnet0

Traffic from intnet1 needs to go out on extnet1 (consider this a default route 
for any traffic not going out on extnet0).

What are some suggested ways of doing this?

Assume addresses are (these are made up, but hopefully help paint the 
picture):

intnet0 - 192.168.50.0/24
extnet0 - 10.10.10.8/30
 - extnet0 address 10.10.10.8.10
 - default route 10.10.10.9
 - broadcast 10.10.10.11

intnet1 - 192.168.60.0/24
extnet1 - 10.10.10.12/30
 - extnet1 address 10.10.10.14
 - default route 10.10.10.13
 - broadcast 10.10.10.15

So far I have created vlans via a switch on each interface to multiplex the 
connections:

vlan10 - 192.168.50.0/24 and vlan20 - 192.168.60.0/24 come in on a single 
cable to int0.

vlan50 - 10.10.10.8/30 and vlan60 - 10.10.10.12/30 come in on a single cable 
to ext0.

However, since I have the defaultroute set for 10.10.10.13 all traffic from 
intnet0 is going out on vlan60 whereas i want it to go out on vlan50.

Am I going about this the wrong way?

Thanks,

Geoff

no port ralcgm - render CGM graphics with ImageMagick?

[Anton Shterenlikht]

I use ImageMagick quite a lot. Never came across this before, but
now I need to view some CGM drawings and realised that I need
ralcgm:
http://www.imagemagick.org/script/formats.php
http://www.agocg.ac.uk/train/cgm/ralcgm.htm

As far as I can search, there is no ralcgm port for FBSD.
Is that so?

Is there anybody else who is interested in having this port?
I might try to create one, if there is some support from the
community.

many thanks

I'd like to make it easier for my dad to shutdown a server. Instead of
having him plug a keyboard, log on as root (with a complicated
password) and finally type shutdown -h now, is it possible to assign
this command to some unused key like eg. Syst? Even better, send this
command only if the key is hit eg. three times within 2 seconds?

truss is buggy?

[Laszlo Nagy]

Apparently, the truss trace tool has a bug. At least I was told that 
the tracer program should not change the return value of the getppid() 
call inside the traced process. Here is an example program:


%cat test.c
#include stdio.h

int main() {
  while(1) {
  sleep(5);
  printf(ppid = %d\n, getppid());
  }
}

%gcc -o test test.c
%./test
ppid = 47653
ppid = 47653
ppid = 47653 # Started truss -p 48864 here!
ppid = 49073
ppid = 49073
ppid = 49073


I cannot install strace, beacuse my platform is amd64. What other 
options do I have?


Thanks

I have a similar setting, but it requires X, WindowMaker and a
Sun Type 6 USB keyboard. :-)

Short explaination: I have assigned the command

xterm -class SHUTDOWN -fg black -bg red -e shutdown -p now ; read 
DUMMY

to the key combination Ctrl+Alt+(I) - the switch off or moon
key on the top right. This combination is impossible to press
accidentally. (Without Ctrl and Alt, this key closes the X session
and leads back to xdm for login.)

You could add a clickable menu entry or desktop icon with this
command, but make sure it's not accidentally clicked. :-)



If your father is already logged in, he could shutdown -p now
(or using an alias) from an xterm. He needs to be in the wheel
(or at least operator?) group for this.



What about pressing the power button on the machine itself, it
should perform a shutdown -p now (shut down and power off).



By tht eay, the key you're refering to is named System Request,
or SysRq.

Could not find package - using ports

I'm upgrading all the ports I have installed and the command I

Sad news is that for every single package it tries to fetch it doesn't 
find anything, so it uses the ports, and it needs lots of time to compile 
everything. (gnome, X, firefox are not so fast to compile!)

Portupgrade won't install packages -- it'll upgrade your ports using
the ports tree.  If you want the latest software, you need to compile
using ports.  Packages are built once, when the X.X-RELEASE comes out.
 Did you read the portupgrade man page?

If you upgraded (you never specified from what version you upgraded
from), say from 7.0-RELEASE to 7.1-RC1, you will get the latest
packages by deinstalling your current packages and reinstalling using
pkg_add.

That's not entirely true. The portupgrade port installs a program
called portinstall. According to its manpage, portinstall can
-a- install from ports (compile), -b- install from packages
or -c- install from packages only (where it works similar to
pkg_add).

Sidenote:

Another fine tool is pkgdb -aF (comes with portupgrade port)
to keep pkg_added packages and stuff installed by either
portinstall or manual make install in synchronization.
It's good to run this command before and after altering
something on the installed packages. :-)

 pkg_add).

Portinstall is just an alias for portupgrade -N

The reason that portupgrade -P was not using packages is that, by
default it fetches packages  built against the tree that's on the
install disks, so there wont be any for updated ports.

You can set portupgrade to fetch packages for the 7-stable development
branch (you can google for how to do this). For the most part this will
work, but occasionally there will be library problems.

kernel options for ipv6 firewall

[beni]

Hi,

I'm trying to reconfigure and recompile my kernel to use a ipv6 firewall.
So far I added this to the kernel (from http://techie.devnull.cz/ipv6/ipfw2-
ipv6-dummynet/) :

# IPFW2
options IPFW2
options IPFIREWALL_VERBOSE  #enable logging to syslogd(8)
options IPFIREWALL_FORWARD  #enable transparent proxy 
support
options IPFIREWALL_VERBOSE_LIMIT=100#limit verbosity
options IPFIREWALL_DEFAULT_TO_ACCEPT#allow everything by default

and I tried this also (from http://www.kame.net/~suz/freebsd-ipv6-config-
guide.txt) :

options IPV6FIREWALL
#options IPV6FIREWALL_VERBOSE
#options IPV6FIREWALL_VERBOSE_LIMIT=100
#options IPV6FIREWALL_DEFAULT_TO_ACCEPT
But all I get is an unknown option error when I do a make buildkernel.

I've added also this to my /etc/rc.conf :
#IPv6
gateway6_enable=YES
ipv6_enable=YES
#ipv6_gateway_enable=YES
#ipv6_router_enable=YES
ipv6_network_interfaces=vr0 tun0

# Enable ip6fw.
ipv6_firewall_enable=YES
ipv6_firewall_type=client
# ipv6_firewall_quiet=NO
ipv6_firewall_quiet=YES   # suppress rule display. (By default, it's NO)
ipv6_firewall_logging=YES # enable events logging. (By default, it's NO)
ipv6_firewall_flags=  # Flags passed to ip6fw when type is a 
filename

pf is enabled for ipv4.

So what option(s) do I need to use a ipv6 firewall in my kernel ?

That information is out of date.  ipfw now handles both IPv4 and IPv6 without
any extra kernel configuration required.  All you need to do is write rules
that reference IPv6 addresses etc.


I've added also this to my /etc/rc.conf :
#IPv6
gateway6_enable=YES
ipv6_enable=YES
#ipv6_gateway_enable=YES
#ipv6_router_enable=YES
ipv6_network_interfaces=vr0 tun0

# Enable ip6fw.
ipv6_firewall_enable=YES
ipv6_firewall_type=client
# ipv6_firewall_quiet=NO
ipv6_firewall_quiet=YES # suppress rule display. (By default, it's NO)
ipv6_firewall_logging=YES   # enable events logging. (By default, it's NO)
ipv6_firewall_flags=# Flags passed to ip6fw when type is a 
filename


Take a look at /etc/rc.firewall6 -- that just does for IPv6 what rc.firewall
does for IPv4.  Your settings above should enable it to work, but you'll need
to put the correct network numbers, prefix len and IP address into the
rc.firewall6 file.  (Not a particularly nice piece of design: configuration
information like that shouldn't require you to edit the actual rc script.)


pf is enabled for ipv4.


pf will also do IPv6 automatically.  With pf's really very handy indeed
feature of being able to deduce from the interface name the IP numbers /
networks to put in the rulesets, you can write rules that operate on IPv4
only:

 pass in on $ext_if inet proto tcp \
from any to $ext_if port ssh   \
flags S/SA keep state  \
(max-src-conn-rate 3/30, overload ssh-bruteforce flush global)

IPv6 only:

 pass in on $ext_if inet6 proto tcp \
from any to $ext_if port ssh\
flags S/SA keep state   \
(max-src-conn-rate 3/30, overload ssh-bruteforce flush global)

or both:

 pass in on $ext_if proto tcp\
from any to $ext_if port ssh \
flags S/SA keep state\
(max-src-conn-rate 3/30, overload ssh-bruteforce flush global)

Although this last is internally transformed into two rules, one for the
IPv4 address on the i/f, and the other for the IPv6 address.  See 'pfctl -sr'
for the generated rules.  So on my machine, that becomes:

pass in on de0 inet6 proto tcp from any to fe80::240:5ff:fea5:8db7 port = ssh flags 
S/SA keep state (source-track rule, max-src-conn-rate 3/30, overload 
ssh-bruteforce flush global, src.track 30)
pass in on de0 inet proto tcp from any to 81.187.76.162 port = ssh flags S/SA keep 
state (source-track rule, max-src-conn-rate 3/30, overload ssh-bruteforce 
flush global, src.track 30)

(not that I've yet seen any ssh bruteforce attempts over IPv6)

If you need bandwidth limiting facilities, you can do this with pf as well,
but you will have to compile a custom kernel to enable the ALTQ features.
It's equivalent to IPFW's dummynet but there are subtle differences in the
way it operates that may or may not be a show stopper for you.


So what option(s) do I need to use a ipv6 firewall in my kernel ? 


Same as you need for either pf or ipfw with IPv4 -- in fact, you frequently
don't need to modify the GENERIC kernel at all.  You can just load ipfw as a
kld.  Same with pf, unless you need to use altq which still requires some
compiled-in stuff in the kernel.

Cheers,

Matthew

Cpu and memory clock tool

[Jeff Laine]

Hello everybody.

I've been fiddling with some memory modules on my laptop and realized that I 
had no idea what frequency memory was running.

So is there any tool to measure such things like FSB and memory clocks 
under FreeBSD?

Not sure of how detailed the output will be regarding FSB (check your

[ re. a bootable CURRENT backup system on a USB stick]

 I am very sorry for this inaccurate information.  As it turns out,
 only the GENERIC kernel is bootable, my custom configuration doesn't.
 On the bright side, this indicates some feature missing from my
 normally very lean kernels, nothing is kaputt beyond repair.  I'll
 just have to find out which module just has to be in the kernel to
 make it boot from an USB stick.

The custom configuration uses the new USB2 stack, whereas GENERIC
still includes the older one.  When replacing USB2 with the old stack,
I can reliably boot the system from the stick.

I have another backup on a MMC card in a $5 card reader, but that one
boots with USB2.

The USB stick which only runs on the old stack identifies as:

  ugen1.2: SanDisk at usbus1
  umass0: SanDisk product 0x5151, class 0/0, rev 2.00/2.00, addr 2 on usbus1
  pass0: SanDisk Cruzer Micro 8.02 Removable Direct Access SCSI-0 device
  da0: SanDisk Cruzer Micro 8.02 Removable Direct Access SCSI-0 device
  umass0:  SCSI over Bulk-Only; quirks = 0x

I don't know if any quirks would make this product work.  To me it seems
as if it has to do with bulk handling?

Re: How can I link two separate internal networks to two separate external networks

[Michael K. Smith]

Hello Geoff:


On 12/22/08 4:06 AM, Geoff Roberts ge...@apro.com.au wrote:

 Hi,
 
 I have a FreeBSD 7.0 box with pf.
 
 I have two internal networks (intnet0 and intnet1) and two internal networks
 (extnet0 and extnet1).
 
 extnet0 and extnet1 are two different gateways to the internet.
 
 I only have one physical internal (int0) and one physical external (ext0)
 interface.
 
 Traffic from intnet0 needs to go out on extnet0
 
 Traffic from intnet1 needs to go out on extnet1 (consider this a default route
 for any traffic not going out on extnet0).
 
 What are some suggested ways of doing this?
 
 Assume addresses are (these are made up, but hopefully help paint the
 picture):
 
 intnet0 - 192.168.50.0/24
 extnet0 - 10.10.10.8/30
  - extnet0 address 10.10.10.8.10
  - default route 10.10.10.9
  - broadcast 10.10.10.11
 
 intnet1 - 192.168.60.0/24
 extnet1 - 10.10.10.12/30
  - extnet1 address 10.10.10.14
  - default route 10.10.10.13
  - broadcast 10.10.10.15
 
 So far I have created vlans via a switch on each interface to multiplex the
 connections:
 
 vlan10 - 192.168.50.0/24 and vlan20 - 192.168.60.0/24 come in on a single
 cable to int0.
 
 vlan50 - 10.10.10.8/30 and vlan60 - 10.10.10.12/30 come in on a single cable
 to ext0.
 
 However, since I have the defaultroute set for 10.10.10.13 all traffic from
 intnet0 is going out on vlan60 whereas i want it to go out on vlan50.
 
 Am I going about this the wrong way?
 
I think this will work.  Let's assume:

$vlan10_if - macro for your tagged VLAN 10 interface
$vlan20_if - macro for your tagged VLAN 20 interface
$vlan50_if - macro for your tagged VLAN 50 interface
$vlan60_if - macro for your tagged VLAN 60 interface
$vlan50_gw = 10.10.10.9
$vlan60_gw = 10.10.10.13

pass in on $vlan10_if route-to ($vlan50_if $vlan50_gw) from any to any
pass in on $vlan20_if route-to ($vlan60_if $vlan60_gw) from any to any

That would be in conjunction with your NAT's and any RDR's as well.

Mike

Re: truss is buggy?

[Dan Nelson]

In the last episode (Dec 22), Laszlo Nagy said:
 Apparently, the truss trace tool has a bug. At least I was told
 that the tracer program should not change the return value of the
 getppid() call inside the traced process. Here is an example program:

It looks like the ptrace() syscall is the problem:

DESCRIPTION
 The ptrace() system call provides tracing and debugging
 facilities.  It allows one process (the tracing process) to
 control another (the traced process).  The tracing process must
 first attach to the traced process, and then issue a series of
 ptrace() system calls to control the execution of the process, as
 well as access process memory and register state.  For the
 duration of the tracing session, the traced process will be
 ``re-parented'', with its parent process ID (and resulting
 behavior) changed to the tracing process.

I imagine that also explains why a truss'ed program will die if you
kill -9 the truss process.  It looks like the reset parent when
trussing behaviour appeared back in 1996 (sys_process.s r1.21).  The
fix would probably be to store the pid of the tracing process somewhere
other than p_ppid...

I did that and would not do it again for a massive upgrade: 
http://lists.freebsd.org/pipermail/freebsd-questions/2008-August/180336.html


Using freebsd-update for a (minor version) upgrade to 7.1-RC1 and after 
that using 7.1-RELEASE packages for a portupgrade will probably take 
less time overall.


See the 7.1-RC1 announcement on how to do the first part: 
http://lists.freebsd.org/pipermail/freebsd-stable/2008-December/047014.html


When it is available, you should upgrade to 7.1-RELEASE, which will take 
less time with freebsd-update from 7.1-RC1 than from 7.0-RELEASE, since 
there are less configuration file changes to be merged.


For the portupgrade, you should have in mind that portupgrade uses the 
ports tree to know what to upgrade to which version. Your ports tree is 
newer than the 7.1-RELEASE packages. Anyhow, if the newest package is 
not available but a newer one than the one installed, portupgrade 
usually works, too. Reading /usr/ports/UPDATING before is still advisable.


You might still run into problems of the nature that kde was used to be 
build against openldap23-client at the time of 7.0-RELEASE, but the 
7.1-RELEASE packages are build against openldap24-client and these two 
ports cannot coexist. With ports this is not a problem, since it can be 
build against either version. (AFAIR, this particular case will work out 
fine, but there was something else requiring manual work besides 
everything listed in UPDATING.)


Probably not for 7.0-7.1, but in some cases removing all packages and 
reinstalling all takes less time than anything else.


Cheers,
Jan Henrik

NFS Cache

[Jonatan Evald Buus]

Greetings,
We are having problems with Record Based Log Shipping from our PostGreSQL
database server that appears to stem from NFS caching the files.
PostGreSQL are continously writing to its WAL files located in the pg_xlog
directory which is shared via NFS
Our program is in turn continously detecting the changes as described in
24.4.4 at http://www.postgresql.org/docs/8.3/static/warm-standby.html and
copying a segment of the WAL file to the local harddisk.

The changes written by PostGreSQL however doesn't appear to be reflected
through the mapped NFS drive until at some later point in time (not sure how
long the delay is, but it appears to be 10+ seconds). The delay causes the
transferred WAL files to become corrupt.
Running the same program directly on the PostGreSQL machine provides the
expected result.

The following is the NFS configuration on both the Client and Server
machines:
sysctl -a |grep nfs
vfs.nfs.downdelayinitial: 12
vfs.nfs.downdelayinterval: 30
vfs.nfs.skip_wcc_data_onerr: 1
vfs.nfs.nfs3_jukebox_delay: 10
vfs.nfs.reconnects: 0
vfs.nfs.bufpackets: 4
vfs.nfs.realign_count: 0
vfs.nfs.realign_test: 0
vfs.nfs.defect: 0
vfs.nfs.iodmax: 20
vfs.nfs.iodmin: 0
vfs.nfs.iodmaxidle: 120
vfs.nfs.diskless_rootpath:
vfs.nfs.diskless_valid: 0
vfs.nfs.nfs_ip_paranoia: 1
vfs.nfs.nfs_directio_allow_mmap: 1
vfs.nfs.nfs_directio_enable: 1
vfs.nfs.clean_pages_on_close: 1
vfs.nfs.nfsv3_commit_on_close: 0
vfs.nfs.access_cache_timeout: 0
vfs.nfs4.access_cache_timeout: 0
vfs.nfsrv.nfs_privport: 0
vfs.nfsrv.commit_miss: 0
vfs.nfsrv.commit_blks: 0
vfs.nfsrv.async: 0
vfs.nfsrv.realign_count: 0
vfs.nfsrv.realign_test: 4069
vfs.nfsrv.gatherdelay_v3: 0
vfs.nfsrv.gatherdelay: 1

Are there other ways of disabling the NFS' cache than using sysctl?
Preferably at mount time so caching is only disabled for the PostGreSQL
mount point.
Alternatively, how is NFS forced to use Direct IO?

Appreciate the input

Cheers
Jona

See the kbdcontrol(1) manpage; the -d and -l options are what you need.

Re: Status of hyperthreading in FreeBSD

 be enabled under that operating system.
 */
 
 I found this in wikipedia at the following link
 http://en.wikipedia.org/wiki/Hyper-threading

Yes, system respond variously to hyperthreading but it's mostly in two
areas:

a) Granularity of locking - systems with big locks like FreeBSD's
Giant was when HTT was new don't scale well in multi-CPU configurations
(logical CPUs) and simply using HTT can expose and increase these
inefficiencies. Modern FreeBSD locking is good enough for 8 cores in
7.x and it's improving in 8.x.

b) Behaviour in multi-core (or multi-CPU) case when individual CPUs or
cores support HTT. This is a scheduler issue - if the scheduler isn't
aware that some logical CPU's are fake and some are not (i.e. if it
treats all of them equally) it could move processes or threads from one
CPU or CPU core to another when it would be much better to move it from
one fake (hyperthreaded) CPU to another within the same real CPU.

There are more similar issues here, but none of them (including those I
described) are applicable to Atom since a) locking in FreeBSD is good
enough for it in recent releases (even in 6.x) and b) there are only two
fake logical CPUs and they really can be treated equally.

Now, with Nehalem design (i7) the system can have a quad-core CPU
(actually, several of those) with each core supporting hyperthreading. A
system with 16 logical CPUs (2 x quadcore x HTT) isn't really strange
any more. The scheduler knows about HTT, so the issues under a) are
much more noticable.

 really that much? i thought maybe 1-2% (just 2 sets of registers).

Screenshots are available :)

I was also surprised because in this case both threads use the same
algorithm with the same requirements on registers. It used to be (in the
days of Pentium 4) that HTT would work best if the two threads used
different sets of instructions and registers (e.g. one doing integer
math and another doing floating point math). I guess they made more
effort this time.

Wireless router?

[Nerius Landys]

I have a PC with FreeBSD set up as a router (NAT). The PC has several
network cards and I'm grouping the internal-facing network cards as a
bridge (promiscuous mode for the interfaces).  Everything works well.

Now I'd like to extend my wired network to include wireless.  I really
have no experience with wireless networks.  I have a couple of
computers that are wireless-ready (a laptop and a Playstation 3 that I
won in a raffle).  Is it possible to somehow add some hardware to my
FreeBSD router PC to make it into a wireless router?  What kind of
hardware would I install?  What is it called?  The PC only has PCI
slots, can you recommend a brand and model of wireless server
equiptment if such a thing exists?  Would a normal wireless card
suffice?  What model should I get?  I would prefer to set up static
internal IPs for my wireless network at home, would this be possible?
Or is DHCP the way to go (I hesitate at the thought of configuring a
DHCP server).

Another way to go is to hook up a standalone wireless router appliance
to my FreeBSD machine's network interface (one of the interfaces).  I
already have such a device, I think it's made by Linksys.  But then, I
would be NAT'ing both through the FreeBSD machine and through the
wireless router.  So it would be a double-NAT so to speak.  Is there
anything wrong with that approach?

So in a nutshell, I have a wired FreeBSD router with multiple ethernet
jacks at home, and I want to extend it to include wireless network.
Any suggestions would be appreciated.  Thanks.

If you already have a wireless router, all you have to do is to turn it into 
an access point to your internal lan. Disable its DHCP server, assign a free 
LAN IP to the router LAN ethernet,plug one of its LAN ports into your switch  
and assign free LAN IPs to the wireless cards of your LAN machines.

That's what I did here at home and works like a charm.

If you need a DHCP server you have to set it up on the FreeBSD router.

 If I'm understanding you right, I'm surprised by that (the native part).
 It make any proprietary software less portable.  You're also tying your
 code into third-party internals, which sounds like a maintenance
 problem.

Yes, but I think that's a fairly small effect.  The packet send/receive
interface involved is generally pretty small, regardless of how you
implement it.

  I would have thought that the likes of Cisco and Alcatel
 etc would would have reusable codebases that abstract the OS and
 minimize OS dependencies.

That's always a goal, of course.  Completely throwing out the protocol
stacks in the OS kernel doesn't make most things more portable, though.
There are a fair number of system parameters that are already
implemented in OS kernels, and reinventing that wheel doesn't buy you
anything. 

 What's the advantage, don't routers usually lead OS's in terms
 of new protocol support?

Protocol support per se is generally fairly independent from the OS in a
hardware router; high level protocols are usually handled in userland,
and low level protocols are mostly a hardware issue.

Sorry for replying to myself but it needed a correction. You CAN use the

IPs.

The WAN port won't matter. It won't be used.

Academic and commercial information tend to be separate topics.  The

find corporate white papers and so forth to give you some ideas.  

I can't think of anything more useful to say unless you have a more

Yes, a supported Wireless net card would suffice. It can be configured
to work in Access Point mode, essentially what a cheap wireless router
would. Instructions in section 32.3.5 here:

http://www.freebsd.org/doc/en/books/handbook/network-wireless.html

While I haven't used FreeBSD in this mode,  from my experience
atheros-based (ath(4)) cards work well.
I have no less than three Dlink DWL-G520 cards and never had any
problems.  This is a rather older model now, newer atheros cards may
need a newer HAL than the one currently in the source tree (e.g. the
Aspire One uses a newer atheros, and needs a custom kernel with some of
the original files replaced. I believe -CURRENT has the newer HAL though).
I recently also got a Linksys WMP 54G that is based on a Ralink chipset
(ral(4)). This also works nicely.

  I would prefer to set up static
 internal IPs for my wireless network at home, would this be possible?
   

Sure. I am using static IPs in all my wireless clients.

 Or is DHCP the way to go (I hesitate at the thought of configuring a
 DHCP server).

   

Configuring a DHCP server is very easy. I've only used it with wired
ethernet though. Have a read at  this:

http://www.freebsd.org/doc/en/books/handbook/network-dhcp.html

 Another way to go is to hook up a standalone wireless router appliance
 to my FreeBSD machine's network interface (one of the interfaces).  I
 already have such a device, I think it's made by Linksys.  But then, I
 would be NAT'ing both through the FreeBSD machine and through the
 wireless router.  So it would be a double-NAT so to speak.  Is there
 anything wrong with that approach?
   

I've used something similar and it worked. Don't know about possible
drawbacks, cause it was only a toy for me. My setup was something like this:

Wireless standalone router (built in NAT) -- FreeBSD system as wireless
client of the router + wired ethernet card -- FreeBSD NAT using pf /
ipfw -- Wired internal ethernet (with DHCP server) -- Wired client(s)

So I guess your approach is also possible.
 So in a nutshell, I have a wired FreeBSD router with multiple ethernet
 jacks at home, and I want to extend it to include wireless network.
 Any suggestions would be appreciated.  Thanks.
   
Probably multiple solutions exist, start up by buying a cheap but
supported wireless card.

 I've tried searching around, but I haven't been able to turn anything up.
 Is there something I'm missing?  Something I should be doing that I'm not?

 You are missing new snd_hda man page reading. RTFM. :)

 1) Read new man page;
 2) Driver provides you two pcm devices for different purposes, so try to use
 both (as man page recommends);
 3) If your system has several audio connectors - try all of them, they are
 not equal any more.
 4) Boot with verbose logs enabled to get much more information about your
 codec and driver operation (as man page recommends);
 5) Connexant audio codecs are rare, so send your verbose output to me, I
 would like to see it.

Should I be asking you about the old snd_hda?  I'm having this same
problem and ignoring it for some time (no sound), but on

FreeBSD aire.franks-development.dyndns.biz 6.4-STABLE FreeBSD
6.4-STABLE #9: Sat Dec 13 18:25:36 MST 2008
r...@aire.franks-development.dyndns.biz:/usr/obj/usr/src/sys/GENERIC
amd64

instead of current.  I read the warning:

 A few Hardware/OEM vendors tend to screw up BIOS settings, thus rendering
 the snd_hda driver useless, which usually results in a state where the
 snd_hda driver seems to attach and work, but without any sound.

In the man page, and I suspect that may be my problem.  Chipset is
Intel.  I played with the bios, but only got it to be worse (snd_hda
not detected at all).

[st...@aire ~]$ cat /dev/sndstat
FreeBSD Audio Driver (newpcm)
Installed devices:
pcm0: Intel 82801G High Definition Audio Controller at memory
0xfdff8000 irq 16 kld snd_hda [20071129_0050] (1p/1r/1v channels
duplex default)

Is there any further info that would help?  I've been limping along on
a usb dongle and it's a bit sad ;)

Thanks,

Yes.

 What kind of hardware would I install?  What is it called? 

Wireless card.

 The PC only has PCI slots, can you recommend a brand and model of
 wireless server equiptment if such a thing exists?  Would a normal
 wireless card suffice?

Yes

 What model should I get? 

Now that's the tricky bit. If you look at the wlan(4) manual page,  you
will see the supported wireless chipset in the SEE ALSO section.

The trick is knowing which chipset a certain card has. It is usually
_not_ listed on the box or on the manufacturer's website, because it
comes with windoze drivers so most of the users don't give a damn about
the chipset. And some manufacturers put different chipsets in different
batches of the same card depending on what they can get their hands on.

If you see a card that you like and you cannot get the name and type of
chipset used, download the windows driver. It will come with an in
information file (.inf) that usually contains the name and type of the
chipset.

 I would prefer to set up static internal IPs for my wireless network
 at home, would this be possible?  Or is DHCP the way to go (I hesitate
 at the thought of configuring a DHCP server).

You could use the wlan_acl module to grant access based on the MAC
address. But it might be better to do it somewhat more sophisticated and
run hostapd(8).

 Another way to go is to hook up a standalone wireless router appliance
 to my FreeBSD machine's network interface (one of the interfaces).  I
 already have such a device, I think it's made by Linksys.  But then, I
 would be NAT'ing both through the FreeBSD machine and through the
 wireless router.  So it would be a double-NAT so to speak.  Is there
 anything wrong with that approach?

It's probably easier. But you'll have to be on the lookout for
vulnerabilities in the router software. 

When I got a wireless card for my desktop, the idea was to make a
wireless conncetion to my laptop. But you have to set up hostapd on the
access point, and wpa_supplicant on the laptop. And the manual pages in
question don't give an overview of the process, and neither does the
handbook. The section of the handbook dealing with wireless networks is
outdated and in need of expert attention. Unfortunately I didn't get far
enough to be that expert.

In the end it was much easier and faster for me to just plug a
cross-cable into the laptop from the desktop. (fast=nice when you're
running rsync(1) or if you're transferring dumps via nc(1))

Hello Nerius,

I simply bought a standard wireless router, turned off all services in 
it except the access list and plugged it in the LAN. The access list 
filters on mac addresses and that level of security is fine where I live.


The wireless router does have firewall, dhcp, port triggering and such 
but I disabled all of those since my FreeBSDs do all of that already.


The wireless router has one port for internet and four ports as a normal 
switch, I don't use the internet port. I just plug in the ethernet cable 
in the switch part as uplink.


I considered having a wifi nic as accesspoint in the FreeBSD main 
router, however, it was better for me to be able to place the wifi 
router for optimal range of the wifi. Turned out that the centre point 
for wifi is not the same as where the main router is


Greetings

/Roger

If you have another PCI slot available in your router, one of these should work:

This is definitely the route I'd go.  I'm a BIG fan of the Buffalo 
wireless access points if they've re-entered the channel near you (a 
patent troll prevented their sale for the last 18 months, but that court 
case was just overturned), as they support DD-WRT.  Failing that, the 
Linksys WRT54GL isn't a half bad unit.


Custom firmware (dd-wrt, OpenWRT, Tomato) also give you a lot finer 
grained control over what happens on the AP.

Re: Wireless router?

[Nerius Landys]

Thank you all for your suggestions.  This will be a project for me
over the holidays.  I decided to go the standalone wireless router
approach.  I will need to figure out how to configure my standalone
wireless router to pass everything through to the internal LAN that
I already have.  Also I don't know too much about security, like how
to prevent eavesdroppers from connecting to my internal network.  One
of you mentioned access lists, and I assume that means I tell the
wireless router which MAC addresses it accepts, and nothing else.  Is
there any other way to provide security?  Like a password-protected
network?  What are the buzzwords for these security schemes?  Which
security scheme do you recommend for preventing random people within
proximity from connecting to my internal netowrk?

Good man!

I already have.  
It's called Bridge mode on most APs-- it does exactly what you 
describe.  Just make sure things like DHCP server are turned off or 
you'll see some... odd breakages.

Also I don't know too much about security, like how
to prevent eavesdroppers from connecting to my internal network.  One
of you mentioned access lists, and I assume that means I tell the

Ugh.  MAC addresses are trivial to spoof-- I usually don't bother with 
using them for security, although I do use 'em to ensure that particular 
machines always inherit particular addresses.



Is there any other way to provide security?  Like a password-protected
network?  What are the buzzwords for these security schemes?  Which
security scheme do you recommend for preventing random people within

Absolutely.  Google for WPA or WPA2; WEP has been broken and is trivial 
to bruteforce, so I'd not bother with that.


Once you get the unit in, feel free to email me off list for 
configuration questions; it sounds like a fun project!

Or let your dad login with his own account and password.  Just add him

write him a little script that does 'shutdown -p now [comment ..]'

Shutdown is cleaner than reboot, runs 'stop' rc.d scripts for all active
