Unfortunately I can't do Make release as it is not Freebsd. It is a

Re: A question about the date Function

date -j -f "%a %b %d %T %Z %Y" "`date`" "+%s" >f0

What does the long form of this command give us that
date +%s fails to do?


It's a contrived example:

date -j -f "%a %b %d %T %Z %Y" "`date`" "+%s" 


  -j says "don't alter the system date" -- this is used if you want
 to read and format a date/time string other than the present time.

  -f says use the following format to read the input date. That's
 %a -- abbreviated weekday name (localized)
 %b -- abbreviated month name (localized)
 %d -- day of month as decimal number, zero padded to two digits
 %T -- equivalent to %H:%M:%S
 %H -- Hour in 24h clock, zero padded to two digits
 %M -- Minute, zero padded
 %S -- Second, zero padded
 %Z -- Time zone name
 %Y -- Year as 4 digits including century.
 (See strftime(3))

Which looks like this:

% date +"%a %b %d %T %Z %Y"
Thu Sep 17 06:31:15 BST 2009

and that just happens to be the default *output* format date produces
without any arguments.  Which is appropriate as the next item on the command
line is

 "`date`"  Rune the date command without arguments and substitute the output
into the command line here as a single argument

  +%s finally, says output the date that was read in as the number of seconds
since the epoch.  This is an argument to the initial date command.

so the end result is that the command reads the current date time in the 
standard
output format, parses all of that then converts it into seconds-since-the-epoch,
using two invocations of the date(1) program to do so. Which is not at all 
efficient
if all you need to do is generate the current epoch time.  Just use

  date +%s

for that.

On the other hand, it does show you how to convert an arbitrary date/time to 
epoch time. eg.:


  % date -j -f "%a %b %d %T %Z %Y" "Fri Feb 13 23:31:30 GMT 2009" +%s
  1234567890

CD doesn't eject from the drive.

2009-09-16 Thread Yuri

I have PIONEER Model DVD-RW  DVR-112D.
I started the command "cdda2wav -v255 -D5,0,0 -B -Owav" to grab audio 
but stopped it with Ctrl-C.
Now disk doesn't eject. Both "eject" command and "cdcontrol -f /dev/acd0 
eject" commands hang, and system log gets messages, see below.


It seems like a bug in atapi driver, since it didn't clear the state of 
cdrom hardware after controlling app died.


Anybody knows how to eject the disk now without rebooting?

Unfortunately, libarchive(3), which is used by tar(1) and cpio(1) on
recent versions of FreeBSD, seems to have only read and extract
support for ISO 9660 archives, and not write support (see
libarchive-formats(5) or
http://code.google.com/p/libarchive/wiki/LibarchiveFormats ).  So
while you could use tar(1) or cpio(1) to extract the contents of the
dvd without mounting it in order to make your change,  you would have
to use some other tool to write the new .iso image, like mkisofs(8)
from the sysutils/cdrtools-devel port.  (And if the original image has
extensions that are not supported by librarchive(3), you could use
something like readcd(1) from that same port instead of tar(1) or
cpio(1) to read and extract it.)

Have you tried mounting it as a vnode ? and mounting it R/W ?

mdconfig -a -t vnode -f file.img
mount -t  /dev/md0 /mnt/rw_dvd

Where  may be cd9660 or some other format of the image.

Pardon my political incorrectness...

If you can't get it to work under FreeBSD, I'm pretty sure that it works 
under Linux:


  mount -t iso9660 -o loop file.img /mnt

(I'm not sure that "iso9660" is the right filesystem type, but "man 
mount" will tell you.)


Once mounted that way you can use it like any other filesystem.

I actually did this once, but it was years ago.

Re: sSMTP, this mailing list, and helo errors

2009-09-16 Thread Chad Perrin
I evidently forgot to disable Sendmail in my rc.conf on the 7.2 machine,
which in turn reminded me that I had forgotten to change the mailer.conf
to indicate my alternate MTA for sending emails.  This means that my
ssmtp.conf file was irrelevant, because sSMTP wasn't being used to send
emails at all anyway.

The relevant lines for mailer.conf, in case someone later on stumbles
across this thread looking for a solution to the same problem, are:

sendmail/usr/local/sbin/ssmtp
send-mail   /usr/local/sbin/ssmtp
mailq   /usr/local/sbin/ssmtp
newaliases  /usr/local/sbin/ssmtp
hoststat/usr/local/sbin/ssmtp
purgestat   /usr/local/sbin/ssmtp

If this email gets through to the list, consider my problem solved and
myself suitably chagrined at having overlooked something that should have
been so obvious to me.

I suspect that the the "long form" is just an example designed to
demonstrate more than one thing in single  line rather than a practical
suggestion.

I used to use it in scripts and never questioned it until for some
reason it stopped working, and I tried the simpler alternative.

My first guess would be DNS. Whenever I see something like a 'host not 
found' of this nature I think "no PTR record". Although I would think wrt 
mail the MX record would matter. My thinking is the two configs you have 
mentioned being identical the problem is a third config somewhere else, and 
first thing I'd look at is name resolution, forward and reverse.

Grab a copy of the transaction with tcpdump or Wireshark. Perhaps the list 
filtering software is seeing mail with a From:  it isn't 
recognizing and blocking. Tcpdump/Wireshark from both hosts and compare for 
differences in the mail headers, e.g., the one that works and the one that 
doesn't. With Wireshark this is easy, just start a capture, send an email, 
stop capture, and use the "Follow TCP Stream" menu option. Or use tcpdump 
and import it into Wireshark.

sSMTP, this mailing list, and helo errors

2009-09-16 Thread Chad Perrin
I moved email from a FreeBSD 6.2 machine to a FreeBSD 7.2 machine.

On both machines, I'm using sSMTP[1] to send email to a mailserver
managed by a shared hosting server, with SSL/TLS authentication.
Everything works, except for one "small" problem -- sending email to this
list.  It has apparently exposed a problem with the setup.  I get a "Helo
command rejected: Host not found" error when sending to this list.

The weird part is that I'm using *exactly* the same ssmtp.conf file on
both the 7.2 system and the 6.2 system.  As you can see -- since this
email comes from the 6.2 system -- that configuration file isn't causing
any problems sending with sSMTP on 6.2, so I'm a little confused about
the cause of the problem.  Where else should I look for a problem?

My MUA is Mutt (and yes, that's using exactly the same configuration file
too).

Thanks in advance for any help.

I found a tip in VirtualBox helps,
and the trick seem to solve the problem.
But, I am not sure this is the right solution.

The trick is, on OpenSolaris (the host system), to type the command.
$ VBoxManage setextradata "My VM name" "VBoxInternal/TM/TSCTiedToExecution" 1
The FreeBSD VMs no more need ntpd to sync the clock.

hi matthew,

i tried this and couldn't make it work before i emailed my question. then
mel answered that the /etc/rc.d/foo scripts ignore environment. and then,
looking closer at man pages, i got the impression that perhaps only /etc/rc
uses the foo_flags variables when it invokes /etc/rc.d/foo scripts.

A question about the date Function

2009-09-16 Thread Martin McCormick
The man page on date has an example showing how to get
an output showing the number of seconds since the Epoch.

date -j -f "%a %b %d %T %Z %Y" "`date`" "+%s"

There is an envokation of date embedded in this command
of

date +%s

I was curious as to what this command does so I tried the long
form and then the short form with:

date -j -f "%a %b %d %T %Z %Y" "`date`" "+%s" >f0
date +%s >f1

I then compared the outputs of f0 and f1 and they are identical.

What does the long form of this command give us that
date +%s fails to do?

Nothing is broken, here. I am just curious. Thank you.

If you're starting service foo, then you should be able to define command
arguments by setting foo_flags="-a -b -c".  This is a convention, and particular
services may use several more specific variables to build a command line
or may simply ignore any flags variable completely, so you'll have to check 
each case individually.



for example, how does one start sshd using /etc/rc.d/sshd and pass it
'-o X11Forwarding=no' without touching a config file?


In this case, setting sshd_flags will work as sshd uses the default rc
start function.

that's right.

when i read in 11.7 of the handbook: "Since the rc.d system is primarily
intended to start/stop services at system startup/shutdown time, ..." i
thought: maybe i'm making things hard by trying to use rc.d scripts when i
could just execute the daemon's binary.

an advantage i imagined of using rc.d is it starts the service with the same
config as at boot so i don't have to remember any config items that might
not be in the daemons config files. maybe all config _should_ be in the
daemon's config files but then i _might_ have been both lazy and forgetful.

You could also just put:

sshd_flags="-o X11Forwarding=no"

into your /etc/rc.conf file.

Pretty much all of the rc.d scripts support the use of NAME_flags being
defined in /etc/rc.conf, which are passed as extra commandline arguments
to the daemon. You should generally check /etc/defaults/rc.conf to see
what you might be clobbering. A small number of scripts may override
this feature from the library, breaking this method, but it's pretty
widely supported.

You don't. Defaults are set in /etc/defaults/rc.conf, overridden in 
/etc/rc.conf. Unless you add the logic yourself in /etc/rc.conf, the 
environment is not looked at.
So this means a one-time edit of /etc/rc.conf:
if test -n "${SSHD_FLAGS}"; then
sshd_flags="${SSHD_FLAGS}"
else
sshd_flags="${sshd_flags}"
fi

Then start with SSHD_FLAGS="-o X11Forwarding=no" /etc/rc.d/sshd start

But this is specific for sshd, as it supports _flags. There's no generic way 
to do this.

Hello Steve:

Another approach would be a cluster of Postfix servers and Dovecot
servers behind PF load balancers.  We have 3 "POP" servers (IMAP/POP), 9
Mail Servers, 2 Defer servers and 5 Filter servers that process over 20
million messages a day without a blip.  We can take individual servers
out of the pool for maintenance, etc.  Everything is fed to a set of
redundant NAS for the data storage and common configuration files.

Regards,

Mike

And providing details of a currently-undefendable vulnerability
to a black hat who did not previously know about it, thereby
enabling the black hat to perpetrate harm that would otherwise
not have occurred, isn't?


The simple act of publishing the fact that a know exploit exists for a
given program compromises nothing. Example:

WARN: The following program(s) have known exploits.

PROGRAM: prog-name
PROGRAM VERSION: 2.4
OS:  FreeBSD-7.2+
EXPLOIT: Potential to render HD inaccessible
PATCH:   NONE AVAILABLE
SUGGESTION:  If prog-name is not imperative to system
 performance, remove it and consider using a similar
 product by another author.

A simple solution that affords the end user the right to make an
informed decision. I realize that governments, especially
socialistic/fascists ones use the terms 'censorship' and 'secret' with
the term 'For their own good' interchangeable. I would hate to see the
open-source community, especially FBSD embracing that philosophy.



Are you really serious?  What you posted (your example) does absolutely no good 
for the average user.  What are you going to do?  Stop using the program?  And 
how can you possibly make an "informed decision" when you know nothing other 
than the fact that something is wrong?


OTOH, it's all an attacker needs to start digging around and successfully break 
in.


Think about this.  A guy wants to find a pot of gold.  He goes to a field and 
finds 12,000 pots.  Where does he start?  Along comes someone who believes in 
"freedom of speech" and says, "Well, I don't know where the gold is, but that 
pot over there is a good place to look.  I happen to know that it was put there 
recently and there was a lot of secrecy surrounding it."


Or an attacker approaches a seemingly impenetrable castle, trying to figure out 
how to defeat the army inside.  He knows he's going to have probe every area 
and lose many men in the process in order to find a weakness he can exploit.


Then one soldier, believing in "freedom" sends them a message that there's a 
weakness on the north face of the wall.  He doesn't tell them exactly where, 
but he's managed to focus their efforts on the area most likely to allow them 
to breach the wall and defeat the army inside, he's reduced the attacker's 
efforts by three fourths and reduced their losses as well.


You clearly don't understand the advantage that hackers have over the average 
user.


Rather than censorship, how the FreeBSD team handles issues like this is good 
stewardship.  They have a responsibility to the community to protect them. 
They do that by not irresponsibly trumpeting known weaknesses before a solution 
is available to the end users.

Change one file in an ISO image

Hi list,

I need to change one file in an existing ISO image. It is a DVD image btw.
Unfortunately I dont have many options of changing the fie before creating
the image.

Mounting is not the issue, copying data neither but the ISO is also
bootable. There must be a simpler solution as in copying all the content
with cpio and making it bootable. OS on the DVD is WinPE btw.

Does anyone have some pointers for performing this action?

Can lagg0 failback be prevented?

2009-09-16 Thread Peter Steele
I posted this on the -net list but didn't get any responses. I'm hoping a wider 
audience might help.



We're using the lag driver to provide automatic failover in case of a network 
outage. The default configuration looks like this:



lagg0: flags=8843 metric 0 mtu 1500

options=19b

ether 00:a0:d1:e3:58:26

inet 192.168.17.40 netmask 0xf000 broadcast 192.168.31.255

inet 192.168.22.11 netmask 0xff00 broadcast 192.168.22.255

media: Ethernet autoselect

status: active

laggproto failover

laggport: nfe1 flags=0<>

laggport: nfe0 flags=5



If nfe0 was to fail, we get an (almost) automatic failover to nfe1:



lagg0: flags=8843 metric 0 mtu 1500

options=19b

ether 00:a0:d1:e3:58:26

inet 192.168.17.40 netmask 0xf000 broadcast 192.168.31.255

   inet 192.168.22.11 netmask 0xff00 broadcast 192.168.22.255

media: Ethernet autoselect

status: active

laggproto failover

laggport: nfe1 flags=4

laggport: nfe0 flags=1



The problem we're having is when nfe0 comes online again, a failback occurs 
making nfe0 active again. This causes a momentary network outage that we want 
to prevent. Is there a way to configure the lagg device to stay with the 
currently active interface, even if the MASTER interface comes back online?

This is *EXACTLY* what I was looking for!

The possibility of loosing an extremely small amount of data far
outweighs the possibility of a multi-hour outage where 3,000 users are
receiving "can't reach the POP3 server" errors.

Besides, our incoming SMTP gateway boxes cache all incoming email for 24
hours, and we can re-deliver any message to the back-end we wish during
that window.

I really try my best to design/implement all the systems I can like our
networks... multiple paths and extremely quick convergence. Being able
to take a box down to test/perform an upgrade, or during a failure
without client impact is well worth any initial large learning curve imho.

Thanks,

Steve

Now, that is a different kettle of fish.  This is a job for cyrus imap.
I suggest googling for 'cyrus murder' -- this is almost, but not quite,
a fully resilient mail store / IMAP system.  Your mail store is divided
into frontend IMAP protocol servers which handle user auth etc. and back-end
mail stores.  The protocol layer servers are fully resilient and you can
fail over a user session at will, but the mailstores don't quite get there:
mail is replicated across different stores, but actions modifying the mail
store are not transactional across all the mail stores. Or in other words,
you can lose a small amount of data if one of the mail stores goes bang at
precisely the wrong moment.  Even so, it will do better at keeping multiple
copies of a mailstore in synch than any locally scripted rsync setup.

Matthew

Ok, I'm back up and rolling again.

Thanks Matthew, and the others who replied off-list for all of the feedback.

One thing that I forgot to ask in my original post was that of clustering.

In our production network, we have a cluster of perimeter MX's, and a
similar setup for our submission boxes (it's been a couple of years
since we've strictly enforced AUTH for all clients).

What I don't have, and have always wondered about, is live redundancy
for the IMAP/POP services.

I know that this would be a challenge to some degree considering the
high volume of data changes.

Perhaps a carp(4) setup between a couple of MDA's, where when the
primary is up, a constant rsync pushes the data to the backup. Or
perhaps a combination of rsync for manual changes, and a method to have
the primary write the emails to a local disk, and a network disk
simultaneously?

If anyone has a setup that has redundancy for their IMAP/POP services,
and a method to keep the changing data relatively up-to-date, I'd love
to hear about it.

Cheers,

Steve

You could try the following;

1) Update your ports tree.
2) Remove: /var/db/pkg/pkgdb.db
3) Run: /usr/local/sbin/pkgdb -Ffuv
4: Run: /usr/local/sbin/portsdb -fUu
4) Run: /usr/sbin/pkg_version -vIL=

Now run portupgrade as you normally do and see what transpires.

If that still fails, install /usr/ports/ports-mgmt/portmanager
Then run it as thus: portmanager -u -l -y -p

I have had great success in getting updates completed successfully with
portmanager when portupgrade and portmaster both crapped out. I would
suggest that you consider deleting the contents of
the /usr/ports/distfiles prior to running any of the above port utility
programs.

The simple act of publishing the fact that a know exploit exists for a
given program compromises nothing. Example:

WARN: The following program(s) have known exploits.

PROGRAM: prog-name
PROGRAM VERSION: 2.4
OS:  FreeBSD-7.2+
EXPLOIT: Potential to render HD inaccessible
PATCH:   NONE AVAILABLE
SUGGESTION:  If prog-name is not imperative to system
 performance, remove it and consider using a similar
 product by another author.

A simple solution that affords the end user the right to make an
informed decision. I realize that governments, especially
socialistic/fascists ones use the terms 'censorship' and 'secret' with
the term 'For their own good' interchangeable. I would hate to see the
open-source community, especially FBSD embracing that philosophy.

I am still facing this issue.  I have tried several ways of 
rebuilding the index and pkgdb but nothing is changing this 
behaviour.

Doing a 'make index && pkgdb -fu' gets me a portversion list that 
shows nothing needs updating, which is clearly wrong when the cvsup 
just prior to it shows changes in ports I have installed.

'make fetchindex && pkgdb -fu'
is more successful, showing all the ports I need to update 
correctly(?), however, portversion will still do this

> portversion -v | grep png
png-1.2.38  <  needs updating (port has 1.2.40)

> portupgrade -vrR png-1.2.38

I saw someone ask about this in Google Groups on the 14th but he has 
not got an answer yet, so I am not the only one.

How do I fix this?
