This kind of random fishing expedition is unlikely to succeed.  You need
to take a more methodical approach to the problem.

Luckily, Kris Kennaway did a presentation a while ago that teaches you
the *right* way to fish:

REPOST: Re: help requested in fixing disk label mistake

[Scott Bennett]

 A few days ago, I posted here regarding damage resulting from a typing
error and, a few minutes later, posted a followup to correct an error in my
description of the problem.  Thus far I've gotten no responses.  In case the
lack of response is simply due to the message having gotten lost in the flow,
I'm reposting it below.  I hope that someone who is more familiar with the
details of bsdlabels and glabels can help me understand how to correct the
problem because I'm loath at this point to embark upon an ill-informed trial-
and-error experimentation program to recover label and file system(s).

No, gmake can make binaries that work on freebsd. For example, the
Atheme IRC services require gmake, not make on freebsd (at least, last
I checked). It's just a difference in the format of the Makefile.

No.

Broadly speaking ports that build from source install native binaries,

Best RAID setup

[Don O'Neil]

I'm getting ready to setup a new FreeBSD 8.1 64 bit server and wanted to
know everyone's thoughts on which way to go. software RAID 5 (or 10) or
hardware RAID 5 (or 10). I currently have a 3Ware card in one of my servers
and it works great, but I haven't really been keeping up on what the latest
RAID support is. How is the ZFS support these days? Is it production ready?
What about hardware RAID, is there a compatibility list somewhere with what
hardware (or pseudo hardware) RAID controllers are supported? 

 

I'm just looking for the most stable, and production ready RAID that can
handle at least 1 TB disks and create volumes in the 3-4 TB range. Any
thoughts, feedback, caveats, etc. are welcomed.

 

Thanks!

It does not. I just tested it with a file backed md device, and

After the first two steps, I got just zeros, after labeling it, I got

If it does overwrite the label, you most likely specified the da0s1d to

Ah!  That is, in fact, exactly what I did.  I didn't realize

Streams fail, more/less.

[Gary Kline]

The _last_ thing that I need to resolve--or at least to understand, is why
streams suddenly stopped working about two weeks ago.  With all the other
hassles, I didn't want to check and see if streams worked here on my server
--they don't.  The streams stall after a few seconds or a few minutes on my
Ubuntu desktop.  The youtube streams always worked before.  No more.  

Meanwhile I have no trouble downloading source or packages at 110 to 170kpbs .
 But the streams fail: both audio and video.  I have zero idea even where to
 begin looking to fix this problem.

 Anybody know?

 thanks in advance,

 gary


 PS: some audio will streams at very slow rate ... but usually stops after a
 few minutes.

dhcpd does not log

[Toomas Aas]

Hello!

I have isc-dhcp41-server-4.1.2,1 installed on FreeBSD 8.1 amd64 and it  
is working well, except that it generates no log.


In dhcpd.conf I have this line:
log-facility local4;

and in syslog.conf:
local4.*/var/log/dhcpd

The file /var/log/dhcpd exists with permissions 0600, owned by root. I  
have restarted dhcpd and syslogd and the entire server, but this has  
no effect. I have also tried removing the log-facility line from  
dhcpd.conf expecting that after restarting dhcpd the log messages  
appear in /var/log/messages, but they don't.


dhcpd is running with these arguments, as seen by ps:

/usr/local/sbin/dhcpd \
  -q -cf /usr/local/etc/dhcpd.conf \
  -lf /var/db/dhcpd/dhcpd.leases \
  -pf /var/run/dhcpd/dhcpd.pid \

If I try

to repeat the glabel command, then the geli metadata is
overwritten.


That will give you a device node called /dev/label/data.eli, that you
can newfs and mount. Unfortunately, since you already encrypted da0s1d,
you may have to back it up, and restore the data after you've redone it.
I had this problem a few years ago, and I had to back up and restore,
but perhaps it's been made simpler now? Though I doubt it.


I think that this is the problem.

Unfortunately, this step overwrites the label.  If I try
to repeat the glabel command, then the geli metadata is
overwritten.

I think that this is the problem.

the exact drive number, etc., which might change if I reboot

label in the last sector, which is where GELI stores metadata.


You don't have to worry about this. geli uses the last sector for
its metadata and creates a device with one sector less to its clients.
The original device is 2048 sectors, the device geli provides is 2047
sectors:

moby# diskinfo /dev/md0 /dev/md0.eli
/dev/md0512 1048576 20480   0
/dev/md0.eli512 1048064 20470   0


There is no way for the "internal" GEOM to mess with the "external's"
metadata.


That's fine, but I want to label the "external" /dev/md0, not
the "internal" /dev/md0.eli.

What I eventually want to do is to "geli attach" the device
using a name that doesn't depend on drive numbering.



Correct me if I'm wrong anyone.
You need to first label da0s1d

e.g. like so

glabel label data da0s1d

then geli init the labeled device

e.g. like so

geli init -l 256 -s 4096 label/data

then

geli attach label/data

That will give you a device node called /dev/label/data.eli, that you 
can newfs and mount. Unfortunately, since you already encrypted da0s1d, 
you may have to back it up, and restore the data after you've redone it. 
I had this problem a few years ago, and I had to back up and restore, 
but perhaps it's been made simpler now? Though I doubt it.

Use tcpdump to do a capture file. something like this:

tcpdump -i eth0 -n -s 1500 -w sip.cap

then feed sip.cap to wireshark

filter for SIP and observe the SIP conversation

It's also possible to decode the RTP stream

I've been using tcpdump on the asterisk server and both interfaces of
the firewall as well as the log interface. Unfortunately, its not giving
me the answers I want so far. Follow a stream from beginning to end, so
to speak, but I've been having trouble matching it up; especially with
the log.

Is it possible with wireshark to do this kind of matching if I capture
on all these interfaces?


From the wireshark manual page:

INTERFACE
   MENU ITEMS
   File:Open
   File:Open Recent
   File:Merge
   Merge another capture file to the currently loaded one. The
   File:Merge dialog box allows the merge "Prepended",
   "Chronologically" or "Appended", relative to the already
   loaded one.

Looks like doing a chronological merge is what you need. Your machines 
had better have the same idea of what the time is though.

Re: Can't open serial line /dev/cuaa0: no such file or direcotry (2)

[Michael Adams]

Dear Greg,

Thanks for your reply.  I've avoided contacting you because I've been "doing
my homework" in an attempt to get up to speed.  However, I'm delighted to
hear from you, and must congratulate you on your work with Tempcontrol.

In fact, I've overcome the problem with port nomenclature in exactly the way
you suggested, and the error no longer appears.  I simply changed the value
in .temperaturecontrolrc to /dev/cuad0.

I do, however, have other problems with the programme: regardless of the
values that I pass to endtemp, none of the solenoids are responding and I
get no output on screen.

May I discuss this with you further?  Your program seems to be precisely
what I need, but unlike you, my problem in chilly East Anglia is keeping the
fermentation temperature up, not down, for most of the year!

Regards,

Michael Adams

Correct. Currently sysinstall can only perform MBR partitioning

You want GPT partitioning.

Re: How to label a GELI device

[Nikos Vassiliadis]

I have an encrypted partition, /dev/da0s1d.  I can use geli
attach da0s1d and obtain a device /dev/da0s1d.eli, which is a
UFS filesystem.  All that works just fine.

I'd like to label /dev/da0s1d so that I don't have to refer to
the exact drive number, etc., which might change if I reboot
with a USB stick in the system or whatever.  But glabel puts the
label in the last sector, which is where GELI stores metadata.


You don't have to worry about this. geli uses the last sector for
its metadata and creates a device with one sector less to its clients.
The original device is 2048 sectors, the device geli provides is 2047
sectors:

moby# diskinfo /dev/md0 /dev/md0.eli
/dev/md0512 1048576 20480   0
/dev/md0.eli512 1048064 20470   0


There is no way for the "internal" GEOM to mess with the "external's"
metadata.


So, how do I make this work?



glabel apart from the generic device labeling, supports UFS labels which
are *part* of the filesystem, that is, you *don't* have external metadata
living in a sector outside the filesystem. Check tunefs manual page and
specifically the -L option.

HTH, Nikos

I have been trying to get some pointers on my asterisk issues and I've

How do I trace IP packets across the network (pf firewall included)? And
would it be possible to read it visually (human readable)?


1: tcpdump on every machine the packets go through?

2: wireshark (in /usr/ports/net/wireshark). A very nice tool.

In general, probably yes, provided the combination of hardware
and driver actually works properly _all_ the time :)

AHCI is new enough that the occasional hardware erratum or
driver bug might be more likely than with an older technology
such as IDE or ATA.
