It's best to start from [1] and add the extra installation and
configuration steps that you want based on "debconf-get-selections"
and "debconf-get-selections --installer".

"debconf-get-selections" and "debconf-get-selections --installer" have
unset configurations and have multiple-set configurations.

If you run "debconf-get-selections | grep tzdata", there are various
timezones with blank settings.

I don't have Debian box at hand to look this up exactly, but, AFAIR,
the timezone section of "debconf-get-selections --installer" has a
zone set when countries with multiple timezones.

You can go to SGI for suitably large n-way Linux servers.  An SGI UV 2k rack
will go up to 256 Intel E5 processors (2048 cores, 4096 threads), 64TB RAM.

http://www.sgi.com/products/servers/uv/

I don't think the UV has mainframe-style hardware partitioning.  It is a big
NUMA box with a complex hypercube-like node topology.

I've bought the 8 DVD set of Debian 6.0.5 and have set aside

rest would be for the resulting test install and possibly

Are there other routes to my goals I should investigate?



In this thread, and others, there have been an underlying

QUESTION:
Can someone point me to detailed instructions on setting up 
a client and "server" on a single physical computer. As a 
primary motivation for this whole project is learning Linux, 
I foresee lots of related reading :)

Not exactly. 

The openSUSE forum post is about moving the VGA card into a different 
PCIe slot but this was of no help for the Ubuntu user. I guess the 
success of the suggested bypass depends on the motherboard (on some 
models you can find slots which share MB resources which could be 
triggering this warning).

There's no clear solution posted at the Ubuntu bug (or at least I could 
not find it) that's why I suggested that you open a report in Debian :-)

Good. You can point to the Ubuntu bug so developers can see there are 
another users affected by this. Most sure they already know about this 
and can give you some hints to overcome it.

Did you try to diagnose your hardrive with smartmontools? Smartmontools 
uses S.M.A.R.T.[1] technology included in harddrives, and displays info 
about predictable failures, time of use, etc.

I work on IBM mainframes as my "day job".  32-bit IBM mainframes have
a 2 GB address limit.  (That's because, although the registers for
manipulating binary integer numbers are 32-bits wide, the address bus
has only 31 address lines.)  Physical memory in excess of 2 GB could be
installed though.  You could use the extra memory in two ways.  (1)
IBM provides virtual-machine-level virtualization built-in to the
hardware microcode, known as PR/SM (Processor Resource / System Manager).
This can create what are known as LPARs (Logical PARtitions).  You can
divide up the physical memory between LPARs, so that each LPAR does not
exceed 2G.  (2) You can configure some of the memory, either in basic
mode or in LPAR mode, as "expanded memory".  (Think back to the "expanded
memory boards" in the days of DOS.)

This in known in IBM lingo
as XSTORE memory as opposed to CSTORE memory.  Some IBM mainframe operating
systems, such as VM, can use XSTORE memory as a high-speed paging device.
Then, some applications, such as DB2, can use "hyperspaces" or
"VM data spaces" as ways to exploit memory above 2 GB.  I was aware of
these techniques in the mainframe world to exploit memory above 2 GB,
but I'm much less familiar with the world of PC CPUs.

BTW, IBM's 64-bit machines no longer offer a "basic mode".  LPAR mode is
required on all 64-bit machines, AFAIK.

That's one of your hard disks so you definitely have to worry for the above 
errors.

You can get WD diagnostic tool from here:

Data Lifeguard Diagnostic for DOS (CD)
http://support.wdc.com/product/download.asp?groupid=610&sid=30&lang=en

If both SATA drives pass the tests then open your computer case and reseat/
reconnect the SATA cables (or better yet, replace them with a set of quality 
SATA cables).

Another test you can perform is getting the ISO image for SystemRescueCD 
(livecd) 
and boot with it. From here you can check if the errors are gone or still 
present 
(by doing so you can discard/confirm a problem coming from the raid 1 layout 
that 
you have set in your main system because the livecd will see/treat both disks 
independently, not raided).

Sorry, but this is not the proper thread to talk about that. Anyway, I already 
read the other post you sent about the issue but I have no idea on rsyslog and 
remote logging, sorry ;-(

Email management workflow

2012-08-28 Thread Jimmy Thrasibule

Hello,

I have a bunch of email accounts that I connect to using the POP3
protocol and Thunderbird. This is mainly done to keep the different
servers clean of emails and also to keep a backup of all my emails on my
workstation. Of course, all the emails within my workstation are also
backed up regularly.

Now I'm like the young guys and I get an Android phone. My problem here
is about sent email. I can configure my Android phone to leave the
emails on the server and then remove them later from the server using my
workstation. But as sent emails are saved locally, I will lose the
emails sent from my phone.

I know about IMAP but one of my concerns is to being able to have access
without an Internet connection and I also like the fact to clean out all
my emails from the servers.

Any idea?

How are you querying your DNS servers? 

Send the exact command and what's the output you get in both cases.

Anyway, I would avoid using wildcards for DNS registries.

Also, check this for some hints:

Will a wildcard CNAME take precedence over a named CNAME record?

According to Wikipedia, that's a Windows tool.

If the content of the original CCD file was protected then ccd2iso may have 
problems for doing the conversion.

Well, what you had to do with the ".img" file is convert it to ISO using 
ccd2iso to check if that works and thus discard a problem within the 
application ;-)

Fine. I can see now in another post from you that you finally got rid

IPSec Point to Point Tunnel Has Double Latency in One Direction

2012-08-28 Thread Chris Dos

I've been trying to figure this out for a few days now, but I'm at a loss.  
Time to ask the experts.

I have two Debian Squeeze boxes that I'm creating a site to site vpn for.

Followed this how to: http://wiki.debian.org/IPsec

I can ping both sides of the internal interfaces, but pings from one side, have 
twice the latency of the other
side.  I'm at a total loss about why this is occurring.

Site Office Network:
External Interface on eth0: 50.194.128.49/28
Internal Interface on eth1: 172.18.38.1/24
ip route add to 172.18.108.0/24 via 50.194.128.49 src 172.18.38.1

So about the same latency from the Office to the Branch over the VPN compared 
to pinging the external

64 bytes from 172.18.38.1: icmp_req=5 ttl=64 time=136 ms

Pretty much double the latency going over the VPN compared to just pinging the 
external interface directly.


I can find no reason why this is occurring.  Anyone have any ideas why this is 
happening?

How to find the lost 'installed application' - OpenOffice.org Impress

2012-08-28 Thread Ryan Duan

Hi,
I use Debian squeeze, now it cannot find OpenOffice.org-Impress to
open odp and ppt files, but Impress does have been installed, I can
use command "ooffice -impress" to open it.

I'm sure the following packages are well installed:
openoffice.org, openoffice.org-impress, openoffice.org-gnome.

Details:

1. .odp file handler isn't Impress, .ppt file handler missing, Impress
missing in "installed applications" list.
Right click .odp file, expect to open it with Impress by default,
but the default handler app becomes "Open with Document Viewer".
Further more, click "Open with other application...", in the
"installed applications" tab, I can find all of "OpenOffice.org"
entries except "OpenOffice.org Impress".

2. In the main menu "Applications -> Office", there are all the
OpenOffice entries except "OpenOffice.org Impress". I didn't remember
when and how I got it lost.

3. The above phenomena occur in my default user - the one created
during the installation of Debian.
I created a new user with menu "System -> Administration -> Users
and Groups" with the account type being "Desktop User", in the new
user, everything is OK!

4. I tried reinstall or dpkg-reconfigure package
openoffice.org-impress, but no help.

Does anybody have good idea to help me fix it?

Thanks!

Ryan

My mobile phone (Nokia E63) offers the option to basically add a BCC
header to all sent emails, which I use to send them to myself – they
then arrive in the POP3 Inbox on my server and my workstation can
download them. Of course, the headers are a bit off, but From: and
To: are usually correct, as well as the Msg-Ids.

"only" meaning 256 terabytes in this case...  I'll be very surprised to
ever see a 32 bit processor that can make effective use of that much
memory.

I'd go for a mixed of online/offline IMAP solution, that way you'll get 
the best of the two worlds: sent messages from the Android (online IMAP) 
phone will be kept/stored at the server side and thus could be then 
accessed/fetched/downloaded from the workstation (offline IMAP) to be 
stored locally.

Just to add to that:
- most IMAP clients offer an option to download and save copies of 
messages for offline access (while also leaving a message on the sever)
- to clean out emails from the server is easy: either delete the mails 
entirely, or move them to a local folder (of course, now that mail is 
only one machine)

Most (if not all) client/server software works fine on a single machine. 
If your goal is to create more complex environments that your probably 
want virtual machines (KVM, VirtualBox, Xen, etc.)

I experienced that it's not wanted, if people talk about pulseaudio and
systemd ;). Regarding to pulseaudio for me there's only one way to go. I
never ever use it. It's bad code, one example is the automated volume
control. While it increase one volume in the audio chain, it decrease
another volume at the time in the same audio chain. This is something
that can't work, for audio engineers it's frowned upon to do such evil
nonsense.

I don't like canons and fanatism, it's a civic responsibility to be loud
in such cases. In Germany male genital mutilation of children in
religious context still is allowed. It's a shame. I'm very sensitive
regarding to canons and fanatism. We are living in 2012, not in the dark
age. Somebody tried to be vox dei on this list and this isn't tolerable.
What comes next in the name of god? Killing People or only mutilation?
Don't use condoms, don't have sex, don't speak skeptical about god?

However, I don't like to write any additional word about this serious
issue.

Ralf

No, usually packages for the kernel-rt are as good as a self build
kernel, but to keep knowledge about Linux Rt it's good to build the
kernel and perhaps minimal better optimization of the kernel to my
machine + minimal better optimization of other things, might result in
an noticeable improvement.

Do I hear an echo? ;)

I mention the UV and Infinite Storage products here quite often.  The UV
and its ancestors, the Altix 3xxx/4xxx IA64 beasts, are a different
class of machine sold into a different market.  The SGI boxen are used
exclusively by HPC customers.

The ES7000 and Aviion 25K were used exclusively in traditional
commercial business environments, nearly exclusively hosting databases,
although I did hear of a few large MS Exchange deployments on 16-way
ES7000 boxen.

The CC-NUMA members of the Altix line can all be partitioned into nodes
via programming the NUMALink routers.  Once partitioned, an application
can still span all processors, communicating via MPI and shmem over the
ultra fast NUMALink interconnect.  The MIPS/Irix predecessors, the
Origin 2000/3000 could also be partitioned this way, as well as the IA64
Altix 3xxx/4xxx.  It is relatively common for customers with very large
SGI NUMA machines to partition them from day one, so a failure on a
single NUMA node doesn't take down the entire system.

This isn't quite the same as traditional mainframe partitioning, as you
can't independently assign memory and IO buses to different nodes the
way you can with many mainframe systems.

Yes, it seems there are two hard disks affected. Run:

I would run here the manufacturer's test disk but this one looks it's a bit 
tired. You can keep monitoring the tagged "pre-fail" values and proceed with 
a hard disk replacement as soon as these are quickly increased.

Oh my... consider also to run the manufacturer's smart test utility for this

I can deduce that Maxtor hard disks are very old and would deserve for a 
retirement, eventhough they are still up and (somehow) running.

In your case there are logged errors regarding sectors and I/O errors and this 
is dangerous.

You first sentence indicates I may know even less than I

To verify we are talking about the same thing:
I'm envisioning a Debian repository on the "server".
I will then use netinst to install Debian on the "client".
Later a browser running on the "client" will be able to 
access an HTML page on the "server" or connect to a page on 
the WWW via dial-up.

Sorry to follow up my own post -- I hit "send" too fast.  My response
was given the assumption that PAE gave a 48 bit physical address space;
of course it doesn't.  It gives 36 bits -- 64 GB, which isn't nearly so

May dmidecode be able to step in there?

It shows the DMI / SMBIOS tables.

It happened right after restart! :o)

But I have already solved the problem for me - removing all seemed
Gconf-related config. garbage accumulated over time in the sux-ed user

But I wanted to help to hunt a possible bug here - therefore would to

Are you sure about 1) desktop applications I/O behavior and 2) NCQ?

1) I see noticeable difference for my Intel SSD 320 with different iodepth 
values in fio job.

And as to my current understanding more than one single-threaded I/O 
generating desktop application can easily run at some given point of time. 
And then Nepomuk desktop search accesses the SSD disk with up to 10 
threads at times excluding the Virtuoso database server with its 5,4 GiB 
database – no kidding, thats for real. Then there is Akonadi with the 
PostgreSQL database, KMail, Iceweasel with cache and sqlite3 database and 
whatnot.

As sync I/O calls are synchronous on the syscall side but the kernel is 
still free to schedule the requests in bigger batches on the lower levels 
of the I/O stuck, I´d expect that desktop workloads can cause similar 
effects as somewhat higher I/O depths as one.

Indeed running fio with numjobs=64 instead of iodepth=64 gives similar 
results with that Intel SSD except for higher context switch rate and CPU 
usage. (I can dig out those results if wanted.)

2) I am not sure about NCQ tough. I´d never disabled it on my tests. The 
Intel SSD 320 reports a queue depth of 32 with hdparm -I. It may not make 
much of a difference, I don´t know. Your seek time argument makes sense to 
me. But then I thought that the SSD firmware may have bigger chances to 
combine requests into erase block sized units when it gets more data to 
deal with at once. So it may make some difference for writes. But I could 
be completely off track with my assumption and I bet only a test will show. 
SSD firmwares are like big black interesting and fascinating boxes to me ;)

Use of the word "server" and "client" is difficult because there are
so many meanings associated with it.  A hardware computer.  A software
program running on a computer.  The side of a communication protocol.

  http://en.wikipedia.org/wiki/Server_(computing)
  http://en.wikipedia.org/wiki/Client_(computing)

When you asked your questions about installing onto a system I think
the common assumption would be that you meant you had a physical
hardware computer system and would be installing a Debian system upon
it.  It may be to a different partition on the disk so as to preserve
other systems but only booting one at a time.  In other words, it
isn't possible to install on hardware using the same hardware as the
source and the destination.  Only one is running at a time.  The
installation to the detination would overwrite the source.

If instead you already have a computer system running and you want to
use that same computer system for running an instance of Debian such
that you end up with *both* your currently running system *and* a
newly created Debian system running on the same hardware _then_ the
solution you need is a virtual machine running on your present system.
(As was suggested by Andrei.)  Because you would be wanting to
simulate more than one computer system on the same physical hardware.
One would be the host system.  One or more would be vitual systems
running upon it.

In that case you would want to create a virtual machine that will act
as your client.  Then you can install upon your client virtual machine
using your host machine as the server.  That is certainly possible.
People do it all of the time.

What is your host machine operating system?

Hopefully it will be Debian.  After all this is the debian-user
mailing list.  (smile) But from a technical standpoint it could be any
of a variety of host operating systems.  Some will be easier to work
with than others.  You would need to set up a virtual machine upon it
and then use it as your test client.

This is a somewhat scary question to answer.  Scary because it is
really quite a simple thing to set up a web server and to browse it
using a web browser.  Surely you are already using a web browser.
Making it very confusing that you would even need to ask about a web
browser.  Just use whatever web browser you are normally using.  The
hard part is setting up a virtual machine, configuring the network and
networking bridge, installing an operating system on it.  In this the
task and mighty labor lies.

But to answer your question the most popular web server is Apache with
a variety of improved higher performance followers such as Nginx or
Lighttpd.  And for a web browser Firefox and Chromium are probably in
the lead with others such as Epiphany, Konqueror, Midori in the pack
behind them.  And there are text console web browsers such as lynx,
w3m, elinks which are very useful too.

Networking for kvm virtual machines

2012-08-28 Thread James Allsopp

Hello,
I'm trying to learn more about networking and set up BIND, LDAP and
Nagios on a KVM virtual machine. The VM works great and I can ssh into
it from the host, and view the nagios pages from the host. However the
VM gets the address 192.168.1.x and the host is 192.168.1.2.

What I really want to do is set it up so that the VM just appears as
another machine on my network I can view from anywhere on my network.

I set up a bridge on the host, configured as below in /etc/network/interfaces;
auto lo
iface lo inet loopback

auto eth0
#iface eth0 inet dhcp
iface eth0 inet manual

auto br0
iface br0 inet static
address 192.168.1.2
network 192.168.1.0
netmask 255.255.255.0
broadcast 192.168.0.255
gateway   192.168.1.1
bridge_ports eth0
bridge_fd 0
bridge_hello 2
bridge_maxage 12
bridge_stp off

If anyone has any suggestions on how to do this I would be very grateful.

James

Sawfish wm won't start from gdm3

2012-08-28 Thread Rick Macdonald

I recently (finally) upgraded from lenny to squeeze. All seems well 
except if I choose the sawfish window manager from the gdm3 greeter, the 
dialog goes away and it just sits with the debian logo and the stars 
background. I can't find any error messages anywhere (~/.xsession-errors).


If I start up gnome with the default wm, metacity, I can kill metacity 
and run sawfish from an xterm:


killall metacity; sawfish &

Any ideas why it won't start from the gdm3 greeter?

Regards,
Rick

Well, I've looked into it, and that's not going to work.  The mobo
you suggested has stuff on it for which there are no connector holes
on the back of the case.  The built-in connector holes on the back
of the case support A/C power (of course), PS/2 mouse, PS/2 keyboard
(small-size PS/2 connectors in both cases), 2 USB ports, 2 serial ports,
and one parallel port.  In addition, there are knock-out plugs for what
looks like a joystick/MIDI port and what looks like line-in, line-out,
and microphone connectors for on-board sound.  I would have to knock
out the metal plugs, but at least the case can handle a mobo with
on-board sound.  But there are no connector holes for VGA output, DVI
output, or an Ethernet jack for a network connection, nor are there
knock-out plugs for the same.  The power supply connector to the mobo
is a 20-pin connector.  The case is just not designed to handle modern
mobos.

I can't even identify the mobo.  With no RAM, the BIOS won't initialize.
It just beeps at me (about 1 second on and 1 second off).  So the BIOS
won't tell me what the mobo is.  I searched in vain for some form of
identification on the mobo silk screen itself, but all I could find
was "Made in China".  Therefore, I don't know what kind of memory it
needs.  I'm afraid this other system is going to be good for nothing
except possibly to be cannibalized for parts.  A clue to its age:
it has a couple of ISA (or possibly EISA) bus slots on it, in addition
to PCI bus slots.  And the video card appears to be VESA local bus.

The fist Infiniband hardware hit the market in the early 2000s.  But its
data rate was only 2Gbps, or ~200MB/s, one way.  This is Infiniband 1x.
 That's 100 times less bandwidth than the memory system in the 32-way
ES7000.  And the latency is over 100 times higher.  Now take into
account that with memory based networking, all that is required to send
a packet is a write to a memory location, and to receive it, all that is
required is to read that memory location.

> that should about measure up to what you're describing, but with tons
> more scalability, no?

Absolutely not.  4x QDR Infiniband is the most popular type in wide use
today.  Its one way bandwidth is "only" 4GB/s, and its one way latency
is still many tens of times greater than the in-memory networking in the
ES7000 we're discussing.  Infiniband 12x QDR is currently used for
switch-switch backbone links and node links in some HPC clusters, and
has a one way data rate of 96Gbps, or 12GB/s, only 60% of the ES7000
memory bandwidth, while its latency is still some 10 times greater.

The absolute "fastest" type of Infiniband is currently 12x EDR, with a
one way data rate of 300Gbps, or 37.5GB/s.  And just as some of the
Internet's fastest backbone links at 10 Terabits/sec have far more
bandwidth that the memory subsystem of a high end parallel server of
over a decade ago, so does today's fastest implementation of Infiniband.
 This shouldn't be surprising.  Just as it shouldn't be surprising than
any AMD socket AM3 or better system has more memory bandwidth than the
decade+ old high end server we're discussing.  Technology doesn't sit still.

Remove 'network' line.  Remove 'broadcast' line.  Let the tool
calculate it from 'netmask'.  That will prevent errors such as in the
above where the broadcast setting is incorrect.  :-)  [It should have
been 192.168.1.255 not 192.168.0.255.]

I don't see any other problem.

I do not set 'bridge_hello' nor 'bridge_maxage'.  I do set
'bridge_maxwait' to 0.  YMMV.

I also use the resolvconf package and therefore also set
dns-nameservers and dns-search but that is a separate thing.

Good memory. I just replaced a Model 6Y080P0 of that family with a

It looks like the HDD associated with sdc is encountering some issues.


And more specifically, "/dev/sdc5" partition.


But is sdc linked to ata4 or ata6? Do these two problems (before and
after restarting) are the same ones or not?


Yes, it seems there are two hard disks affected. Run:

dmesg | grep -i ata[0-6]


After running several short and long tests with S.M.A.R.T. on each of my
3 HDDs, I got these results:

1) HDD associated with /dev/sda looks in some pre-failure state:


(...)


SMART Error Log Version: 1
Warning: ATA error count 454 inconsistent with error log pointer 5


I would run here the manufacturer's test disk but this one looks it's a bit 
tired. You can keep monitoring the tagged "pre-fail" values and proceed with 
a hard disk replacement as soon as these are quickly increased.



2) HDD associated with /dev/sdb verifies


(...)


(this is the one that looks the healthiest, actually).


Agreed.
 

3) The HDD associated with /dev/sdc, which should be in some way broken
(being given the messages that I wrote above from /var/log/syslog), does
not look so through SMART:


(...)

Oh my... consider also to run the manufacturer's smart test utility for this 
one... and make a full backup _now_.



What can I deduce from this? It looks like /dev/sdc is broken but SMART
tells /dev/sda would have more chance being on the verge to broke than
/dev/sdc.


I can deduce that Maxtor hard disks are very old and would deserve for a 
retirement, eventhough they are still up and (somehow) running.



Note that I tried exchanging SATA cables, to no avail.


In your case there are logged errors regarding sectors and I/O errors and this 
is dangerous.

Thanks for both answers. I effectively removed the very old one,
installed at its place a brand new HDD. This way, I disconnected the one
which was SMART-recognized as sick, and put a new one which now contains
/home/*

This looks perfect, I just had to modify /etc/fstab accordingly (to
modify one UUID value for /home) and to use some screwdrivers.

Thanks again for the help. I hope everything will be fine now. I'm just
surprised that SMART actually detected a faulty HDD which was not
causing any troubles, when it said nothing for a drive that was totally
faulty!

PS: It seems to be, that it's possible to "play" this game without
paying for it, but I can't see anything that teaches me how to use vim.
":" and cursor keys? Wow! Everybody, including me knows this and I'm
able to venture a guess when using vim too. That's the benefit of an
idiotic video game? Wasting time with nonsense, while using vim at least
will help to do some work, even without the knowhow to use it in a good
way, but anyway some work could be done. I think visually, not in words,
but anyway, such a game IMO is less good than a written tutorial and
since I'm a dyslexic reading isn't fun for me.
Sorry for the unkind words, but there already is too much nonsense on
our planet and IMHO this isn't good. Tux math isn't perfect, but
tolerable, for a different target group ;).

trouble editing a partition table

2012-08-28 Thread Ross Boylan

A kvm virtual machine has two disks provided by LVM logical volumes.
They are identical; each has 3 partitions.  To get more space I used
lvextend to grow the logical volumes.

My problem is that the partition tables are unchanged; the last
partition should extend to the end of the new disk but it does not.
None of the tools I have used to change that will cooperate.

How can I expand the partition?

Inside the VM the disks are used like this
LVM
software-raid
partition
drive.

Partition 3 on each virtual disk is software RAID1 with the other.  The
resulting device, /dev/md1, is used for an LVM volume group.

The virtual disks were 6G and now are 8G.

I shut the VM of which the disks were a part and attached them to
another VM running squeeze (the main VM is lenny).

above it would not be at all appropriate to call (since LVM is on top of
md1).  All resizing options are greyed out in the edit and partition
menus.  Attempting to click the end of the graphical box toward the top
representing sdc3 does nothing.

Even more reason to use apt-cacher-ng or something similar.  If you have
multiple Debian installations, you will only have to download updates
once.  All Debian installations will get their updates from
apt-cacher-ng.

http://www.unix-ag.uni-kl.de/~bloch/acng/

I'd recommend you use Virtualbox for all of your "test" installations.
So start by installing Debian on the laptop, and include a GUI (the
default is Gnome, but you could pick something else if you already have
a favorite.  

apt-get install apt-cacher-ng

You can even import the deb files from some/all of the 8-DVD set you
bought, so they will be available any machine configured to use this
proxy.  http://www.unix-ag.uni-kl.de/~bloch/acng/html/howtos.html#imp

Configure the laptop to use the apt-cacher-ng proxy by putting
this line in /etc/apt/apt.conf:

Acquire::http::Proxy "http://localhost:3142";;  

Then configure that machine to be a gateway (sorry, I don't have a link 
for a how-to).  As a gateway, all computers on the local network will
get their internet access through the gateway machine.  You will
probably want to configure a DHCP server on the laptop.

So if you had a real network, the ethernet port of the laptop would
connect to a switch, which would connect to many other computers.  They
would all get IP addresses from the DHCP server on the laptop.  The DHCP
server would be configured to tell those other computers that the laptop
is their gateway.

apt-get install virtualbox-dkms

Now you can use virtual machines instead of real machines to set up your
local network.  It works the same as I described above.  You will need
to read up a bit on the networking options that Virtualbox provides.
I think you want "bridged networking", but it's been a while since I've
used it.  You should be able to get ip addresses on your virtual
machines that are similar to your laptop's ip address (192.168.1.1,
192.168.1.2, etc)

http://www.virtualbox.org/manual/ch06.html

When you install Debian in a virtual machine, make sure to specify the
proxy that apt should use (the installer asks you).  Enter it in this
form:

http://192.168.1.1:3142

(make sure that you specify the IP address of your laptop's ethernet
port).

Have fun practicing networking!

-Rob

Acknowledged.  You have dnsmasq configured to assign addresses to
clients to the 192.168.122.1/24 subnet between .2 and .254.

Your bridge is configured for 192.168.1.2/24.

Somehow you will need to route between those networks.

A virbr0 is set up on 192.168.122.1/24.  I believe this to be a NAT
interface.  A NAT interface will allow outgoing connections.  But
obviously no incoming connections can occur.

It is probably being created by libvirt during VM startup.  You
probably have it set up as the network default for libvirt.

You would need to show us your libvirt configuration and tell us what
type of VMs you are using and how you are starting them.  Are you
using KVM?

If you haven't read it then this page is very useful.  Read through
this and it will probably answer a lot of your questions.

where to report bug: Wheezy installer failed on a RTL8169 network card

2012-08-28 Thread Yuwen Dai

Dear all,

I downloaded the latest Wheezy AMD64 version DVD iso image, trying to
install it on a HP notebook with a RTL8169 NIC.  When the installer
detects network, it hangs.  I could switch to other ttys and open a
busybox  shell, but it's useless, the installation could not resume
any more.  I tried a Squeeze  DVD on the same notebook,  the DHCP
process appeared some difficult, I tried several times,  but at last,
it got IP address.  Where can I report this bug?

Best regards,
Yuwen
