RE: Problema entre NFS, LVM y jbd2

[Frank Harbey Sanabria Florez]

Recuerda que cualquier tecnologia de disco va a usar mas IO, y si el proceso es 
pesado pues mas IO, el punto es LVM usa unas tablas para sincronizar sus 
archivos, y si son muchas estaciones pues imaginate, en cambio cuando se lo 
quitas, el disco va a estar "puro" y solo se va a dedicar a copiar, mover, 
crear y pegar archivos, no a sincronizar tablas, directorios, inodos etc. En 
este tipo de soluciones se debe de validar: 
1ro: El tipo de informacion que se va a pasar2do: La tecnologia de los discos, 
buffer, cache, y RPM3ro: Va a tener RAID? 4to: El tamaño promedio de los 
archivos para elejir el sistema de archivos adecuados asi como el tamaño del 
bloque
Con discos de 7200RPM SAS convencionales recomiendo maximo 3 clientes en un LVM 
con NFS (Pruebas propias) de consulta/escritura constante, esa misma 
configuracion pero con un disco extra en RAID 0 se aumenta hasta 10 Clientes, 
pero si lo creas en RAID1 siguen siendo maximo los 3 clientes.
Bueno no me extiendo mas, espero haberte podido ayudar.

Hola, quisiera comentarles algo que me sucedio a ver si me ayudan a comprender 
la raiz
del problema.

Se me ocurrió montar un servidor NFS para compartir los homes de los usuarios 
de la 
oficina, lo más sencillo posible. El servidor lo configuré para que usara todo 
el disco
mediante LVM y el archivo `/etc/export` contenáa la siguiente línea: 
/home192.168.1.0/24(rw,sync,no_subtree_check,root_squash)

Los mapas de automount y los usuarios están en un LDAP (que está en el mismo 
servidor).

Pruebo los clientes y todo funciona correctamente, los homes se montan 
sinproblema. 
Pero al poco tiempo noto que está lento, por algunos momentos se queda
congelado el cliente.

Revisando el servidor me percato que el proceso [jbd2/dm-0-8] esta realizando 
mucho 
trabajo de IO (cuando ejecutaba top, el jbd2 podia facilmente ocupar 80% o mas 
de IO).

Luego de unos dias, pruebas y leer mucho en internet, pruebo cambiando el
archivo exports, de "sync" a "async", y todo funciona perfectamente, el jbd2 ya 
no es un 
problema y aumentó la fluidez de los clientes del NFS de una manera íncreible.

Pero cuando estaba haciendo pruebas de diferente configuraciones, me doy cuenta 
que si
el servidor usa no LVM, el jbd2 no causa problema. Me refiero a que puedo 
exportar las
carpetas con la opcion "sync" y el jbd2 no ocupa todo el IO del servidor.

Entonces la duda es ¿por qué cuando uso LVM tengo que exportar de manera 
asíncrona ?.

RESOLVED: Re: Adding partition(s) to a Debian install pendrive

[rhkramer]

Thanks to all who replied (or read my original post), the problem is resolved.

I followed the instructions in Thomas Schmitt's first reply, and things just 
worked.

I need to try to puzzle out what I did differently the first time--I do know 
one 
difference, I was trying to make a logical instead of a primary partition, 
maybe that had something to do with it.  And, I guess it is possible in all 
the attempts I made, maybe in some of them I hadn't umounted the drive before 
partioning (I'm about 95% sure I did, but ??.

At this point in time, I probably won't file a bug against that document, but 
I'll think it over (sleep on it) and might suggest adding explicit 
instructions (like Thomas').

Also, I learned some other useful things, like lsblk.

Thanks again!

They do not have to be. That wasn't the point of the question.

When the OP was asked about having an internet modem or gateway he
responded "N/A". On behalf of the OP you could perhaps explain what
that means when he obviously has a means of accessing the internet.

Before I discovered the simplicity of using IPv6, I used IPv4.
I just dug out a backup of a configuration file from that time,
/etc/network/interfaces

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
allow-hotplug eth0
iface eth0 inet static
address 192.168.1.19
netmask 255.255.255.255
pointopoint 192.168.1.15

#

The other end had its 19 and 15 switched, naturally.

Hi,

Ah yes. That's plausible. With my previous Linux i would have had to
unplug and re-plug the stick. But Debian 8 noticed the new partition
without that:

  $ ls -l /dev/sdc*
  brw-rw 1 root thomas 8, 32 Aug 18 20:44 /dev/sdc
  brw-rw 1 root disk   8, 33 Aug 18 20:44 /dev/sdc1
  brw-rw 1 root disk   8, 34 Aug 18 20:44 /dev/sdc2
  brw-rw 1 root disk   8, 35 Aug 18 20:44 /dev/sdc3

systemd magic ?

That would be the more likely candidate for failure, because the BIOS
hops on the x86 code in the MBR of which the partition table got
manipulated by fdisk.

As long as we have only one partition of type 0xef and not overlapping
partitions of non-zero type, EFI should be happy. From MBR it takes
only the partition table entry to find its FAT filesystem with the
boot programs.


Now it has to be tested whether or how easily the installer can make
use the files in partition 3.

This looks pre-isohybrid, i.e. two generations behind of debian-cd
for i386 and amd64. I understand arm64 is suitable for CD and USB stick,
too. Some other arches make no difference between CD and disk at all.


Have a nice day :)

This may (or may not) be because it tries to mount the first partition
and finds it's busy (not surprising as it's the d-i itself) and
moves on to the next device rather than next partition.

It also seems to assume that subsequent devices are unpartitioned so
it tries /dev/sdX but not /dev/sdX1.

The good news with my laptop was that putting the firmware on an old
SD card out of a camera worked just fine. No good for the typical
desktop though.

I think /media is that place.

Fdisk does not tries to read the table, it calls the system call to tell 
the kernel to re-read the partition table to update its view of the 
partitions on the device. I guess this is a privileged operation.


Note also that this old system call fails if any partition of the device 
is in use (mounted filesystem, active swap, active RAID member, part of 
an active LVM...). Parted, partprobe and other tools based on libparted 
use a newer system call which does not have this flaw.

It boots via any decent BIOS. I haven't tested EFI boot with it, but I 
don't see why it would not work as the new partition is "regular".

Probably written at a time when it did work. But the installer has moved
on and now it doesn't. It is more important that firmware files can be
loaded from a separate USB stick, so having everything on one stick is of
very minor importance.

A bug against the Installation Guide asking for the removal of this
section looks like a good move. Few would probably use the technique
even if it worked.

The installer ISOs are supposed to be put on the base device of the
USB stick (e.g. /dev/sdc, not /dev/sdc1).
There they establish an MBR partition table which has two partitions:

  $ /sbin/fdisk -lu debian-8.4.0-amd64-netinst.iso
  ...
  Device  Boot StartEnd Sectors  Size Id Type
  debian-8.4.0-amd64-netinst.iso1 *0 505855  505856  247M  0 Empty
  debian-8.4.0-amd64-netinst.iso2   3900   4731 832  416K ef EFI (FAT
 
This is not a very neat one, as Pascal Hambourg wrote meanwhile.
(My program makes it, but it is not to blame because it only follows
the ishoybrid+GRUB layout developed by Matthew Garrett for Fedora.)
Also there is a GPT head block, which is normally not considered valid
because not properly announced by MBR. Nevertheless some partition editors
actively hate it.

The type "Empty" is part of the trick, because EFI ignores it but Linux
is willing to mount it (yielding the overall ISO).

I tried on Debian 8:

  # get rw-permission to /dev/sdc

  $ dd if=debian-8.4.0-amd64-netinst.iso of=/dev/sdc bs=1M

  $ /sbin/fdisk -l /dev/sdc
  ...
  /dev/sdc1  *0 505855  505856  247M  0 Empty
  /dev/sdc23900   4731 832  416K ef EFI (FAT-12/16/32)

  $ /sbin/fdisk  /dev/sdc
  ...

  Created a new partition 3 of type 'Linux' and of size 1.6 GiB.
  Command (m for help): w
  The partition table has been altered.
  Calling ioctl() to re-read partition table.
  Re-reading the partition table failed.: Permission denied

(I wonder by what method fdisk tries to read the table and fails)

In any case it has worked:

  $ /sbin/fdisk -l /dev/sdc
  ...
  Device Boot  Start End Sectors  Size Id Type
  /dev/sdc1  * 0  505855  505856  247M  0 Empty
  /dev/sdc2 39004731 832  416K ef EFI (FAT-12/16/32)
  /dev/sdc3   505856 3915775 3409920  1.6G 83 Linux

Let's hope the USB stick still boots via BIOS and EFI ...

Next one would mkfs.fat a filesystem onto /dev/sdc2 and copy files to it.


Have a nice day :)

Were you able to progress on this issue?
You mentioned initially that, with older kernel, this issue was not seen. Is
that still the case ?

The manpage says that uncorrected machine check errors will lead to a kernel
panic.

Caso esse do linux-firmware-nonfree não funcione tem o firmware-b43-installer

Around 10:30 this morning, it started working again all on its own.  I'm
guessing one of the networking people restarted something.

There is a phenomenon in one of the online communities that I engage with.
A sort of wink-nudge superstition, if you will: "If you want something
to happen, complain in chat about it not happening."  Posting in IRC
didn't work in this case, but apparently posting to debian-user worked.

IPv6 link local addresses are harder to remember, and you must append 
the interface name to them (see D. Wright's reply), assuming that the

Re: Subject: Adding partition(s) to a Debian install pendrive

[Pascal Hambourg]

Le 18/08/2016 à 18:17, rhkra...@gmail.com a écrit :

Is there any way to add another partition after copying the the DVD-1 install
image to the pendrive?


Sure. Just use any partitioning tool as long as it does not choke on the 
invalid layout of the partition table (the two partitions overlap and 
one overlaps the MBR).



I found subchapter 4.3. of the Debian GNU/Linux Installation Guide: "Preparing
Files for USB Memory Stick Booting"
(https://www.debian.org/releases/jessie/amd64/ch04s03.html.en) and tried to
follow some of the instructions--In section 4.3.1. Preparing a USB stick using
a hybrid CD or DVD image, I see:


The hybrid image on the stick does not occupy all the storage space, so it may
be worth considering using the free space to hold firmware files or packages or
any other files of your choice. This could be useful if you have only one stick
or just want to keep everything you need on one device.


Did they really write this ? The last time I created an extra partition 
and tried to use it for such purpose, it didn't work. The installer just 
seemed to skip any partition on the same device as itself. I had to 
manually mount the extra partition to some directory I don't remember 
(had to check into the installer logs /var/log/syslog) so that the 
installer eventually could find the firmware files on it.



From the above, I inferred that I should be able to create a 2nd partition
after copying the DVD-1 image to the pendrive


You mean a third one : the Debian installer ISO hybrid images, at least 
for i386 or amd64, already define two partitions : one for the ISO 
filesystem and one for the EFI boot.


, but I tried quite a few

approaches (that I might describe in a follwup email if someone really wants
to know) and I'm beginning to believe it can't be done that way.

And, that, instead, you have to follow the procedures in section 4.3.3.
"Manually copying files to the USB stick \u2014 the flexible way".


This is a completely different approach.

In any case, note that Windows or other OS's may not see more than one 
partition on a USB pendrive. I still wonder how it makes the differences 
with a USB disk.

To remind ourselves:

  I wish to connect two laptops via Ethernet

He has internet connectivity. Stick both machines into the router. Set
them up with addresses and routing. Verify they can communicate. Neither
machine need be capable of connecting with the outside world.

OP is seeking to connect exactly 2 PCs. Both SLAAC and DHCP are
overkill in such case IMO. I don't see what's so inconvenient in ipv6
link-local for such simplistic setup.

/etc/mailname has to be sensible for your situation. I usually have to
edit it to get something which makes sense in my situation.

How did telnet go?

You cannot create another partition with cfdisk?

Please show the output of 'lsblk' when the stick is plugged in.

The latter is certainly what I meant earlier. I find it very
convenient, just by using an alias and function (which I deliberately
avoid below). Here's the networking on my laptop as normally
configured wirelessly (with uname -a; /sbin/ifconfig -a;
ip route show; ip neigh show) and then when I connect to a
host with cat5 cable, and back again. (I edited out the lo
interface for brevity):

I doubt that was it. A metre of coax will have a delay of 10-20ns,
which was the blink of an eye to hardware of that era. Collisions would
have been detected by abnormal levels, which is why termination of the
cable was such a big deal. Coax-based Ethernet was basically analogue
video technology. Except for, as you say, the damn' stupid 50 Ohms...

Subject: Adding partition(s) to a Debian install pendrive

[rhkramer]

Is there any way to add another partition after copying the the DVD-1 install 
image to the pendrive?  

I found subchapter 4.3. of the Debian GNU/Linux Installation Guide: "Preparing 
Files for USB Memory Stick Booting" 
(https://www.debian.org/releases/jessie/amd64/ch04s03.html.en) and tried to 
follow some of the instructions--In section 4.3.1. Preparing a USB stick using 
a hybrid CD or DVD image, I see:


The hybrid image on the stick does not occupy all the storage space, so it may 
be worth considering using the free space to hold firmware files or packages or 
any other files of your choice. This could be useful if you have only one stick 
or just want to keep everything you need on one device.

Create a second, FAT partition on the stick, mount the partition and copy or 
unpack the firmware onto it. For example:

# mount /dev/sdX2 /mnt
# cd /mnt
# tar zxvf /path/to/firmware.tar.gz
# cd /
# umount /mnt


From the above, I inferred that I should be able to create a 2nd partition 
after copying the DVD-1 image to the pendrive, but I tried quite a few 
approaches (that I might describe in a follwup email if someone really wants 
to know) and I'm beginning to believe it can't be done that way.

And, that, instead, you have to follow the procedures in section 4.3.3. 
"Manually copying files to the USB stick \u2014 the flexible way".  

I'll characterize those as, generally, partition the USB stick, then add the 
installer image (and, iiuc, you have to use a different install image than the 
DVD-1 .iso.) and a different procedure.

Am I missing something?

PS: Aside: The "instructions" above don't address creating a second FAT 
partition, only copying stuff to it after it is created--I may send a patch to 
the maintainer of that document after I fully understand the situation to make 
it more clear.

6 feet is sensible. This may be why modems and routers come with
6-foot cables, the cheapest guaranteed to work. Shorter could give
problems with cheap devices.

But there's no harm in the devices themselves being closer,
eg stacked, as long as the ventilation works and you don't have our
sort of weather (often >100°F outside).

In days of yore, there was a minimum distance on coax because
every transmission was effectively a broadcast, and had to pass a
certain distance (≡time) before any reply would be recognised *as a
reply* rather than the transmitter hearing itself transmitting.
And if you had a problem, everyone on that segment would share it too.
They say half a metre, but we were not allowed anything less than
one metre. And 50Ω, not 75Ω TV cable!

Cheers,
David.

   You know it makes sense to do this. :)

I had never manually edited /etc/mailname. I took whatever what put there by
the debian installer perhaps as modified by whatever packages I installed and
by running dpkg-reconfigure exim4-config.

As per another post, on thakaa running wheezy I have

   qobi@thakaa>cat /etc/mailname 
   thakaa.ecn.purdue.edu
   qobi@thakaa>tail -n 1 /etc/aliases
   root: q...@purdue.edu
   qobi@thakaa>

and it does correctly forward mail to root to q...@purdue.edu.

On upplysingaoflun running jessie I have

   qobi@upplysingaoflun>cat /etc/mailname
   ecn.purdue.edu
   qobi@upplysingaoflun>tail -n 1 /etc/aliases
   root: q...@purdue.edu
   qobi@upplysingaoflun>

and it does not. I have tried putting each of
   upplysingaoflun.ecn.purdue.edu
   ecn.purdue.edu
   purdue.edu
in upplysingaoflun:/etc/mailname and none of them work. The debian installer,
perhaps as modified by dpkg-reconfigure exim4-config put
upplysingaoflun.ecn.purdue.edu in upplysingaoflun:/etc/mailname

   But it does qualify a bare qobi or root correctly.

Neither thakaa (wheezy) nor upplysingaoflun (jessie) will qualify a bare qobi.
I don't care about that. It would be nice to fix (i.e. send to @purdue.edu)
but is not crucial.

Thakaa (whezy) but not upplysingaoflun (jessie) will ultimately get mail
addressed to a bare root to q...@purdue.edu. That is what I would like to fix
on upplysingaoflun (and all of my other machines running jessie).

Thanks for everyone's help on this.

Re: exim4 under jessie vs wheezy

[Jeffrey Mark Siskind]

   I would bet you do not recall what you answered to the questions regarding
   mail config when installing wheezy.

I kept records of what I answered to those questions when installing sarge,
etch, lenny, squeeze, and wheezy.

   If you have a backup copy of /etc/exim4 you could diff and see.

All my machines save two have been upgraded to jessie. One (thakaa) is running
wheezy and one is runnign squeeze. I just tried on the machine running wheezy.

I just tried thakaa (wheezy) and it did correctly send mail that was addressed
to root to q...@purdue.edu. But it did not on upplysingaoflun (jessie).

I don't understand the files in /etc/exim4. I didn't create them. I just ran
dpkg-reconfigure exim4-config and edited /etc/aliases and
/etc/exim4/passwd.client (and more recently /etc/mailname on upplysingaoflun;
it has been unchanged on thakaa since install).

Any help on how to fix this would be appreciated.

I have frequently used shorter ones.  I think that the shortest I have ever 
actually used was 30 cm. (12") (Cat 5 and Cat 5e.)  So far I have never had 
occasion to use a short Cat6 patch cable.

Are you not on the Internet at all?  I thought that your Windows computer did 
have a *limited* connection, at which rate you must have a modem of some 
kind, albeit possibly internal.

Sort of, but not directly.

Ethernet and fast-ethernet have minimum cable lengths specified.  There
is no minimum cable length specified for gigabit ethernet (1000BASE-T).

For gigabit ethernet, what matters is that none of the crosstalk
parameters are exceeded.  So, any length of cable *as long as it
certifies as CAT5e/6/6A* will work for gigabit ethernet.

In practice, you'll find good CAT6 1m patch cables readly available,
I've never seen anyone bother selling anything shorter than that, but
YMMV.

Because I learned one thing here already (Gigabit ethernet usually doesn't 
require crossover cables), I'll see if I can learn something else ;-)

Back in the "good ole days" there used to be a minimum segment / cable length 
for an Ethernet cable--I don't recall to what all it applied--i.e., I don't 
recall if it applied to thick Ethernet, thin (coax) Ethernet, Cat 5 and Cat 6, 
all of the above or just some of the above.  I always used a minimum of 6' and 
that worked for me.

Does that apply for Gigabit Ethernet?

Have you run aplay -L?  Can you run amixer set Master 85% then alsactl

Subject: "No soundcard"-problem after reboot on 1005HA without speakers

Hello

I have a Asus Eee PC 1005HA on which I run Jessie. The thing is that the
speakers have been physically removed and I am having trouble getting
audio to work via the headphone jack.

However, if I run

# apt-get remove --purge alsa-base pulseaudio

and then reinstall them both and reboot it works perfectly. If I go to
alsamixer I see HDA Intel, Chip: Realtek ALC269 and:
cat /proc/asound/cards
0 [Intel]: HDA-Intel - HDA Intel
   HDA Intel at 0xf7db8000 irq 44

But when I reboot the computer again I'm back to square one and my
soundcard can't seem to be found.

$ lspci | grep Audio
00:1b.0 Audio device: Intel Corporation NM10/ICH7 Family High Definition
Audio Controller (rev 02)

# alsamixer
cannot open mixer: No such file or directory

also if I open the gui pulse mixer no sound card is found.

# cat /proc/asound/cards
--- no soundcards ---

# alsactl init
alsactl: init:1758: No soundcards found...

# journalctl | grep snd

MSI/MSI-X
Aug 18 15:16:02 noether kernel: snd_hda_intel :00:1b.0: no codecs
found!

I can then purge and reinstall to make it work temporarily again which I
tried a number of times just to make sure that the behavior is
consistent.

How can I make alsa/pulse remember my card after purge/reinstall?

produce sound.

And that tells us that running Pulseaudio (or alsa-base post-install
script) requests to load such kernel modules.

It's simple.

Make your laptop enter this 'broken' state, in which no soundcard is
'found'. Execute /sbin/lsmod, redirect its output to some file.

Make your laptop enter 'correct' state, execute /sbin/lsmod again,
redirect the output to some other file.

Compare two outputs, put the difference in /etc/modules. Since such
approach is much of a band-aid - expect the things to break again once
you'll upgrade to next Debian version.

You presumably have a modem/router already. The Debian machine doesn't
have to use it as gateway to the internet. Set up routing for it to send
packets to the local network only.

For you, I would suggest trying a different mirror.

$ host http.debian.net
http.debian.net is an alias for httpredir.debian.org.

This redirection service works very well for some people, and very poorly
for other people.  You appear to be in the latter group.

You can either select a single mirror directly from:
https://www.debian.org/mirror/list

(the single mirrors are listed at the bottom of the page)

or you can use one of the country-code round robin services, such as:
http://ftp.us.debian.org/debian/
http://ftp.ca.debian.org/debian/

(the round robins are listed at the top of the page).

Obviously you would want to choose a country that's close to you,
network-wise.

I have also experienced a MASSIVE problem with apt-get in the last week
or so.  I don't know if it's the same problem you're having, or totally
unrelated, but I am going to piggyback on your thread.

I have my problem at WORK only.  At work, I am trapped inside a firewalled
network.  I have no control over the firewall.  The entities who control
it are mysterious dark wizards who do not reveal themselves or their
secrets to mere mortals like me.

One of the past features of this firewall was a "transparent" (worst term
ever) HTTP proxy with forced authentication (user name and password).
I was able to plead to get an exception in place.  HTTP connections coming
from my desktop workstation's IP address weren't required to perform a
Windows Active Directory login to the HTTP proxy.  So I put a Squid proxy
on my workstation and told all of the Debian servers to use that for apt.

This worked well enough for years.

Now, starting last week, the problem is that when I try to apt-get update,
the files coming from security.debian.org HANG at 100% complete.  It
looks something like this:

qobi has been qualified by Exim. The mail is accepted and makes its way
to dynamo.ecn.purdue.edu.

A mail loop, if I am not mistaken. My thoughts would now be turning to a
server misconfiguration.

Frequent Hash Sum mismatch on jessie-backports with apt-get update

What's wrong and what would you recommend?

Wordpress sites overzetten

Hoi,

Zit er in Debian ook een tool om Wordpress over te zetten naar een
andere URL of een ander path?  Of weten jullie een goede methode?

Ik doe het nu door de database te dumpen en dan zoek-en-vervang te doen
met rpl. Maar dit gaat niet altijd goed.

Groeten,

Too bad it is WinXP, otherwise you'd have instant connectivity via IPv6

Windows XP supports IPv6. It is just disabled by default, so you need to 
enable it with something like "ipv6 enable". Even Windows 2000 could 
have experimental basic IPv6 support.


SLAAC (stateless address autoconfiguration) requires a properly 
configured IPv6 router sending RA's (router advertisements). Debian 
running radvd can do this.


Or do you mean link local addresses (fe80::/10) ? They're not the most 
convenient for everyday use.

Capturar vídeo mediante firewire

[Xavier Sarsanedas Trias]

Buenas,

Tengo una cámara Canon DV (modelo MV950) y quisiera pasar/capturar el 
vídeo a mi sistema Debian 8.5 mediante firewire.


Los puertos firewire de mi torre estan en una tarjeta PCI. Esta misma 
tarjeta la he utilizado en sistemas Windows sin problemas.


Tengo instalados los siguentes paquetes:
-dvgrab
-kdenlive
-kdenlive-data
-libavc1394-0
-libdc1394-22
-libiec61883-0
-libraw1394-11

Mediante el comando "lspci -vv" me devuelve la siguiente información:

04:07.4 FireWire (IEEE 1394): ULi Electronics Inc. M5253 P1394 OHCI 1.1 
Controller (prog-if 10 [OHCI])

Subsystem: Belkin Device 0519
Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- 
Stepping- SERR- FastB2B- DisINTx-
Status: Cap+ 66MHz+ UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- 
SERR-  no me devuelve nada

lsmod | grep firewire --> me devuelve lo siguiente:

firewire_ohci  39523  0
firewire_core  56665  1 firewire_ohci
crc_itu_t 12347  1 firewire_core

Mi intención es utilizar la aplicación "Kdenlive" que utiliza "dvgrab", 
así que des de terminal he intentado lanzar el comando "dvgrab -i" y me 
devuelve el siguente mensaje:


rom1394_1 warning: read failed: 0xf414
error reading config rom directory for node 1
Error: no camera exists

A que se puede deber mi problema?
Me falta un driver para la videocamara?
Me falta algun módulo para cargar en el sistema relacionado con el 
firewire?

La configuración de la tarjeta PCI puede no ser la correcta?

PD: todos los comandos mencionados los he ejecutado como usuario "root".

Un saludo.

>From what I can gather of the thread, both of your machines have
gigabit interfaces. That's good as it means the Auto-MDIX feature is
virtually guaranteed be supported¹. So, you need not worry whether
your cable is crossover or not.

All you need to do now is statically configure both machines to be
in the same IP network. It does not really matter what numbers you
choose as long as they are valid, but convention dictates that you
should use one of the private networks as listed in RFC1918:

https://en.wikipedia.org/wiki/Private_network

As you are only going to have two machines on this network you could
a /30. In fact given there won't be a default gateway host you could
probably get away with a /31. But there is no need to make life
confusing: you can just use a /24, so your network has use of all of
the last octet of the address, e.g. 192.168.1.*.

So, let's say you did choose 192.168.1.0/24. Just configure one
machine as 192.168.1.1 and the other as 192.168.1.2 with a netmask
on both of 255.255.255.0. If either of them insists on needing a
default gateway you can just put the IP of the other machine there.

Your Debian machine is probably saying that it's "attempting to
establish a connection" because it has detected that you've plugged
in an Ethernet cable that has carrier (has the electrical properties
of a working Ethernet network), and is now trying to automatically
configure that interface with DHCP.

That's most likely going to fail because you don't have a DHCP
server on your "network"—unless you *did* happen to have a DHCP
server running on one of those two machines.

Since this setup is very limited and isn't going to change, I would
just statically configure the network on both machines. Setting up a
DHCP server would be just one more thing to learn.

Once your network is working you can use the same tools that you use
over the internet to transfer files over your local network. So,
things like scp, sftp and so on. If your purpose in direct
connection is to have a secure link that needs no encryption and
you're satisfied that it needs no encryption², then you could get
faster transfers with tools like netcat.

Cheers,
Andy

I would bet you do not recall what you answered to the questions regarding
mail config when installing wheezy. If you have a backup copy of /etc/exim4
you could diff and see.

Regarding receiving mails from root from one machine and routing them to
another you should tell the local exim what to do. It used to ask related
question when configure/reconfigure.

The most simple way to do this is to use the default satellite config. This
is also good for the reason that you usually have one MX for your domain.

Then for the root account you usually define alias to some admin user
account/mailbox.

Just keep it as simple as possible

example of test envs /etc/exim4/update-exim4.conf.conf

MX server

dc_eximconfig_configtype='internet'
dc_other_hostnames='mxhost; test.home; *.test.home'
dc_local_interfaces='192.168.40.40; 127.0.0.1; 127.0.0.1.10025'
disable_ipv6=true
dc_readhost=''
dc_relay_domains=''
dc_minimaldns='false'
dc_relay_nets=''
dc_smarthost=''
CFILEMODE='644'
dc_use_split_config='false'
dc_hide_mailname='false'
#dc_hide_mailname=''
dc_mailname_in_oh='true'


MX client

dc_eximconfig_configtype='satellite'
dc_other_hostnames=''
dc_local_interfaces='127.0.0.1'
dc_readhost='test.home'
dc_relay_domains=''
dc_minimaldns='false'
dc_relay_nets=''
dc_smarthost='192.168.40.40'
CFILEMODE='644'
dc_use_split_config='false'
dc_hide_mailname='true'
dc_mailname_in_oh='true'


On both we do something similar to

cat /etc/aliases
# /etc/aliases
mailer-daemon: postmaster
postmaster: root
nobody: root
hostmaster: root
usenet: root
news: root
webmaster: root
www: root
ftp: root
abuse: root
noc: root
security: root
root: admin_account


Resulting in
From: 
Cron Daemon 
  To: 
r...@gw.test.home

From: 
Cron Daemon 
  To: 
r...@maistor.test.home

In the MX machine mailbox for the admin_account
