This is the 'standard'/*EXPECTED* behavior of 'mail', and has been, 
since
the early 1980s.   (I still use 'mail' as my standard mail client'.)

If invoked _without_ specifying a maibox, 
  1) mail that is written to another mailbox is deleted from the inbox 
on exit.
  2) mail that was read, but _not_ written/deleted is saved to 'mbox'.

If invoked *WITH* '-f', messages are not deleted/moved on exit.  you 
must 
_explicitly_ perform any desired actions.


You've found a bug in the _documentation_, not the progam.  :)


ok, I might make a patch for mail.1 when
I have the time.

Thanks

Ha-ha... Ah those were the days..., but does anyone remember the "old" way
of building the kernel in the 2.2.8 days? I was just getting started doing
the basic system setup/admin things in those days. Back then (1998 or so) I
did not have access to broadband, so I did not even update the sources back
then, but I knew that it was a good idea to remove devices from the GENERIC
kernel that I did not have--thanks to the book by Greg Lehey. (Even though
the version of "The Complete FreeBSD" I bought is so out of date I cannot
bring myself to throw it away--it was my guide back in those days.)

Does anyone else remember "The Complete FreeBSD"?

of tweezers, bar copper wire, a magnifying glass, and a potato with two

Exactly the same, in geli the encryption is done per sector. 


I asked a similar questions to the OPs in the geom list and didn't get
an answer. Geli doesn't need or isn't using any advantages of XTS. And
CBC in geli is actually equivalent to ESSIV (see the previously linked
wikipedia page). 

In the end I went with 128 bit aes-cbc since it's the fastest setting
and Bruce Schneier recommends 128 over 256 AES as being more secure.

If you "don't know" what strength encryption you need, and/or the difference
between the methods, you need to hire a data-security professional to examine
your situation and make recommendations appropriate for _your_ needs.

'CBC' -- [C]ypher [B]lock [C]hainig -- is well-suited for strictly -sequential-
data access.   Try reading the blocks of a large (say 10gB) file in *reverse*
order and see what kind of performance you get.

I think I can: FreeBSD 4 on a Pentium 1 with 64 MB EDO RAM.
The make buildworld took 24 hours. The kernel itself, if I
remember correctly, required 3-5 hours, of course without
much tweaking. :-)

Precompiled packages are very helpful on such systems. Only
"top level ports" that _need_ compiling should be touched
(e. g. mplayer due to the options). With today's FreeBSD OS,
you can do many things by control files (loader.conf et al.)
which previously required at least rebuilding the kernel
(e. g. firewall, divert).

That's a fully normal make time on such a system. I've been experiencing it
on FreeBSD 5 and 7 (with ATA disks and 768 MB SDR-SDRAM).

There is no real way to speed it up, except to replace the hard disk with a
SSD. But that's only for I/O, not for compiling itself.
You also won't benefit from using the -j parameter (maximum number of jobs),
because the P4 does not seem to support it.

There's not much you can do to improve the system performance.
You _can_ few things to streamline the system, but that won't be a
_significant_ change.

Plan your builds to take place when you don't use the system interactively,
or use the "nice" command to give building a lower priority. It will last
longer, but can be run in the background without noticing it.

Don't complain about build times until you compile world and kernel on a 150
MHz Pentium 1 with 64 MB RAM. :-)


To give you some impressions of real-work build times, see those
examples:

FreeBSD 5, 500 MHz P2 system:
# make buildkernel KERNCONF
1:11
# make buildworld
3:54

FreeBSD 5, 2 GHz P4 system:
# make buildworld buildkernel
2:13
# make buildworld
1:58
# make buildkernel KERNCONF=*
0:25
# make installkernel KERNCONF=*
30s

On the same system:

A portupgrade of XFree86 server:
2:12
And mplayer including nearly all options:
1:19

FreeBSD 7, 2 GHz P4 system:
# make buildkernel KERNCONF=*
1:05
# make buildworld
3:54


Even worse:

# time make buildkernel KERNCONF=* -D USBDEBUG

There are programs in ports like mbmon and xmbmon to easily

correlation between the expected release date and the actual date is
purely coincidental. Just my 2¢ on the matter.



not disagreeing per se..but just a reminder that with the excellent

 I beiieve the winner is OpenOffice and its kindred;
still compiling after 2.75 hours on 4x3ghz and 8gbytes memory.  The
various Javas also take a while

Thanks for the tips! But I have already tried these commands.
With 2,4,6-core temperature is displayed, but with 8 cores is not :(
Probably will have to arrange PR ...

XTS-AES is a standard devised specifically for disk encryption - it
supports operations on sectors that aren't divisible by the cipher
block size.

See  
http://en.wikipedia.org/wiki/Disk_encryption_theory#XEX-based_tweaked-codebook_mode_with_ciphertext_stealing_.28XTS.29

I personally would be fine with AES-CTR mode, since I don't see the
need to defend against the mythical "strong" adversary who can write
arbitrary bits to unused sectors and then ask to have them decrypted.
AES-CTR doesn't (by itself) have any integrity check.

AES-CBC is fine, but the ciphertext is larger than the plaintext.

geli - selecting cipher

[Wojciech Puchar]

i need high speed disk encryption (many disks running in parallel, lots of 
data movement). i have processor with AES-NI.


geli give 150MB/s performance (tested from/to md ramdisk) using default 
and recommended AES-XTS


and ca 400MB/s read and 700MB/s write using AES-CBC.

I'm not cryptography expert, is CBC somehow "less secure", and if so is it

I will go for a new FreeBSD version and will move out all data.

you mean just new freebsd or new server? if first there is no need to move

Which version do you recommend?
Shall I go for 9 ?

You could use pkg_add -r xorg to get it and all of its dependencies
installed. I usually use that, in combination with ccache to speed up
compiles called by portupgrade.

mail(1) save command does not work as in the man page

[Anton Shterenlikht]

According to the man mail(1):

 save(s) Takes a message list and a filename and appends each message
 in turn to the end of the file.  The filename in quotes, followed
 by the line count and character count is echoed on the user's
 terminal.

However, it seems the mail is copied, but not
deleted on exit:

$ mail -f mbox
Mail version 8.1 6/6/93.  Type ? for help.
"mbox": 1 message

"somefile": 1 message
>   1 me...@bristol.ac.uk   Wed Jul 25 16:36  46/2045  "kuku"
& q

So the mail was copied to  file, as expected.
However, it's still in mbox file too:

$ mail -f mbox 
Mail version 8.1 6/6/93.  Type ? for help.
"mbox": 1 message
>   1 me...@bristol.ac.uk   Wed Jul 25 16:36  46/2045  "kuku"
& q
$ 

This shouldn't happen. According to the man page
the expected behaviour is that message 1 should
be deleted from mbox on quit.

Any comments?

This is strange. src/sys/dev/usb/usbdevs says this:

product HUAWEI E140B0x140b  3G modem

This means that your product is supported

Is this line in your usbdevs?

There is something very, very simple wrong. I just do not see now what
it is.

I have the feeling that your modem is not recognised while it should be
as it is known to FreeBSD.

(as you can't use wildcards in sysctl oids, bleh)

It is all done by usbconfig

usbconfig without any parameters gives you a list of devices. One entry
should look like this:

ugen0.4:  at usbus0,

You enter then

usbconfig -u 0 -a 4 dump_device_desc

Hi,

Thanks for your reply.

I tried switching the USB ports and have some information which could 
help you to help me :


usbconfig -u 0 -a 2 dump_device_desc :
ugen0.2:  at usbus0, cfg=0 md=HOST 
spd=FULL (12Mbps) pwr=ON


  bLength = 0x0012
  bDescriptorType = 0x0001
  bcdUSB = 0x0110
  bDeviceClass = 0x
  bDeviceSubClass = 0x
  bDeviceProtocol = 0x
  bMaxPacketSize0 = 0x0040
  idVendor = 0x12d1
  idProduct = 0x140b
  bcdDevice = 0x
  iManufacturer = 0x0001  
  iProduct = 0x0002  
  iSerialNumber = 0x0004  <>
  bNumConfigurations = 0x0001

usbconfig -u 0 -a 3 dump_device_desc :
ugen0.3: Conversion> at usbus0, cfg=0 md=HOST spd=LOW (1.5Mbps) pwr=ON


  bLength = 0x0012
  bDescriptorType = 0x0001
  bcdUSB = 0x0110
  bDeviceClass = 0x
  bDeviceSubClass = 0x
  bDeviceProtocol = 0x
  bMaxPacketSize0 = 0x0008
  idVendor = 0x051d
  idProduct = 0x0002

  iManufacturer = 0x0003  
  iProduct = 0x0001  
  iSerialNumber = 0x0002  
  bNumConfigurations = 0x0001

Now what should my devfs.conf contain ? Currently it contains the 
following :


link cuaU0.0 modem
own modem root:operator
perm modem 666

link ugen0.3 usv
own usv root:operator
perm usv 666

link cuaU0.1 apcups
own apcups root:operator
perm apcups 666

Obviously, these entries are incorrect since neither my modem speaks to 
the internet nor is any signal from the APC UPS recognized. I believe 
once I have the correct devfs entries, the whole system should work 
smoothly. But please correct me if I am wrong.


Surprisingly, /etc/usb_modeswitch.d contains no entries for 12d1:140b or 
051d:*. Do I need to reinstall usb_modeswitch.d ? Or can usbconfig 
configure the devices correctly ? I am no expert here, so if yes, I 
would need the complete commands.


Thanks for any help. I am greatly indebted to FreeBSD and its philosophy 
making things 'as simple as possible, but not any simpler' - which has 
helped me learn a great deal about computers in general and managing my 
own computer in particular. But the USB related stuff still beats the 
hell out of me, so I need help here.


BTW, my system now has the usbdump command (installed from sources

Yep, I said this already: before there is no modem /dev/ device
which belongs to the Huawei device and produced by u3g, and before one
can not talk with AT cmds (for example with kermit), it makes no
real sense to think in ppp and fire up ppp;

That would suit the need.


I've tried a bit, alas I'm afraid that for some reason, it won't log my
commands as a user...

I have to try a bit harder.



Either way and back on topic, I'm concerned that the security/snoopy/
port might be broken.

I have not yet seen a reply mentioning success, and have had none on my
side on 8.1-RELEASE (admittedly, I could try on a more up-to-date system).

I got something wrong.

It is all done by usbconfig

usbconfig without any parameters gives you a list of devices. One entry
should look like this:

ugen0.4:  at usbus0,
cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON

You enter then

usbconfig -u 0 -a 4 dump_device_desc

and you should get something like this:

ugen0.4:  at usbus0,
cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON

  bLength = 0x0012 
  bDescriptorType = 0x0001 
  bcdUSB = 0x0200 
  bDeviceClass = 0x 
  bDeviceSubClass = 0x 
  bDeviceProtocol = 0x 
  bMaxPacketSize0 = 0x0040 
  idVendor = 0x12d1 
  idProduct = 0x1803 
  bcdDevice = 0x 
  iManufacturer = 0x0003  
  iProduct = 0x0002  
  iSerialNumber = 0x  
  bNumConfigurations = 0x0001 

You try to find a solution from the other side of the rope. I think we
better start here first.

Well that's my problem exactly, really.

1/ the enable script won't work and will always return an error,
requiring a manual activation
2/ even once enabled, snoopy doesn't get loaded because
/etc/ld.so.preload is not used on FBSD apparently
3/ even when enabled with "setenv LD_PRELOAD /usr/local/lib/snoopy.so",
snoopy won't return any log



>From config.h:
/* Syslog facility to use */
#define SNOOPY_SYSLOG_FACILITY LOG_AUTHPRIV

/* Syslog level to use */
#define SNOOPY_SYSLOG_LEVEL LOG_INFO


>From my syslog.conf:
auth.info;authpriv.info /var/log/auth.log

Yet I'm seeing not a trail in /var/log/auth.log , or messages, or even
in secure


I have however validated that snoopy.so is called, as per the following:

# truss ls /dev/null
[snip]
open("/usr/local/lib/snoopy.so",O_RDONLY,031)= 2 (0x2)
fstat(2,{ mode=-r-xr-xr-x ,inode=548761,size=6952,blksize=16384 }) = 0 (0x0)
fstatfs(0x2,0x7fffe220,0x19,0x0,0x80080053a068,0x0) = 0 (0x0)
pread(0x2,0x80063e2a0,0x1000,0x0,0x80080053a068,0x0) = 4096 (0x1000)
mmap(0x0,1056768,PROT_NONE,MAP_PRIVATE|MAP_ANON|MAP_NOCORE,-1,0x0) =
34366341120 (0x80064c000)
mmap(0x80064c000,8192,PROT_READ|PROT_EXEC,MAP_PRIVATE|MAP_FIXED|MAP_NOCORE,2,0x0)
= 34366341120 (0x80064c000)
mmap(0x80074d000,4096,PROT_READ|PROT_WRITE,MAP_PRIVATE|MAP_FIXED,2,0x1000)
= 34367393792 (0x80074d000)
close(2) = 0 (0x0)


And still no logs...

Re: FreeBSD Stable production version.

[Jakub Lach]

8.3 or 9.1.

Using 9.0 when 9.1 is behind the corner
is going backwards IMHO.

or 9-STABLE if you want your system
evolving up to release, which is nice 
because you can catch and solve all
possible problems one at the time, 
and not be overwhelmed upgrading
only to RELEASE.

I do not wonder. This is the best choice.

But I must say that I moved my machines now all to 10 and I am
surprised how robust it already is.

If robustness is the main concern, I would still recommend 8.x.

Re: FreeBSD Stable production version.

[Damien Fleuriot]

While I participate in this philosophy, a very good point was made on
this list that if everyone waits for x.1 , then x.1 will just be riddled
with all the bugs that nobody (or only a select few) found in x.0

That is the point that decided me to get 9-STABLE for 2 of our new
firewall boxes.

I would agree with that philosophy up to a point. It is definitely a
matter of personal preference; however, for myself, I NEVER install
version X.0 of any software if said software is to be used in a mission

Securituy - logging of user commands

[Damien Fleuriot]

Hello list,



We're currently working towards the PCI DSS certification (Payment Card
Industry) for a project at work.


One of the prerequisites is that all user commands be logged.

We're currently using a very bad hack that takes the last command from a
user's history and sends it to a log server.

This of course is unreliable as a user may entirely disable their
history, or just use another shell to bypass the csh function or whatever.



My colleagues installed Snoopy on debian and it seems to work wonders as
a module which is LD preloaded.


I notice it also exists on FreeBSD as /usr/ports/security/snoopy .


However I face several problems with it, mainly it doesn't seem to log
anything.



As per the README, I have added "/usr/local/lib/snoopy.so" to
/etc/ld.so.preload

I'm not even sure this file is used on BSD ?

As per the man page for ld.so there's no such file:
http://www.freebsd.org/cgi/man.cgi?query=ld.so

Neither libmap.conf nor ldconfig(8) seem to be the answer either.



I've googled for ld.so.conf and found the following 2 posts which seem
to indicate it isn't used either:
http://lists.freebsd.org/pipermail/freebsd-hackers/2003-June/001746.html
http://lists.freebsd.org/pipermail/freebsd-hackers/2003-June/001747.html

The posts mention -current but date back from 2003.



Lastly, I have also noticed that the port installs /usr/local/bin/detect
which I executed and would always reply "something's fishy".

By looking at the (very short) source I noticed the program merely loads
/lib/libc.so.6 , and it wouldn't find it on my system (8.3-STABLE with
/lib/libc.so.7).
Adjusting and recompiling lets the program correctly print "secure" but
it does nothing else.

I have checked that the output /usr/local/lib/snoopy.so module is linked
against libc.so.7 , and it is.



Has anyone ever got Snoopy to work on BSD ?
Might I need to install linux emulation ?

Is there any other port that might do the job and which I could use ?

I'm removing sendmail entirely from an installed system.  I had

the list I have so far:

/etc/mail/* (excluding mailer.conf)
/etc/rc.d/sendmail
/usr/bin/vacation
/usr/libexec/mail.local
/usr/libexec/sendmail
/usr/libexec/smrsh
/usr/sbin/editmap
/usr/sbin/mailstats
/usr/sbin/makemap
/usr/sbin/praliases
/usr/share/sendmail
/var/spool/clientmqueue
/var/spool/mqueue

Is this list complete?  I'm intentionally leaving the stuff for
mailwrapper.  I'm ok with leaving /etc/rc.d/sendmail behind as well,
but it looks like it's not needed by anything (i.e., nothing requires
"mail").


"make delete-old"; see the section "Deleting obsolete files, directories
and libraries" in the handbook.


Even though I have WITHOUT_SENDMAIL specified and the world was built
with that, mergemaster still installs /etc/mail/aliases and
/etc/rc.d/sendmail.  Is there a way to prevent this other than adding
them to IGNORE_FILES in mergemasterrc?


There are other ways, but that's the first one I would think of. Note
that neither of these files can be harmful, and might (especially
aliases) be used by other MTA.




I have same question but from different view point. In my situation I
find it easier to install from scratch to empty disk using .iso file
when moving to an newer version of freebsd. Sendmail is included as part
of the base system. What is best method to totally remove sendmail
including the /var/log/sendmail.st file from rotating?

I'd say it's a matter of personal preference.

We're mostly running 8.3 in production here.


I've recently installed 9-STABLE servers to try them out and fill PRs if
I get problems.


I would encourage you to use 9-STABLE so that you may do the same and
ensure the stability of future releases.

FreeBSD Stable production version.

[Marwan Sultan]

Hello all and Good Morning, Afternoon or evening :)

 I will go for a new FreeBSD version and will move out all data.
 
 My Server is mainly is a MAIL server, sendmail.
 and ofcourse few websites, data.etc..
 
 Which version do you recommend? 
 Shall I go for 9 ?
 or 8.3 is still more fit for a production and bsns server ?
 
 Thank you.

What do you do if the extra patches need some pathnames to be removed
(need a PATCH_STRIP different from those in files/patch-*)?
