   On my embedded systems (beaglebone black, 2 x Arietta G25) I installed

   Since these systems and especially the Ariettas are not as fast as a
   PC the greater update, which additionally includes C++ sources to
   compile takes time (read: hours) to finish. Often I run this over
   night.
  
   Since my PC do the forwarding of requests to the internet, it has to
   run the whole time also.
  
   To circumvent this I access the embedded systems via abduco/dvtm, so
   I can log out while the process keeps running.
  
   The current (shorted decription) workflow is
  
   eix-sync
   emerge ... -f (fetching all items, so the connection to the internet

   emerge ...(starting the compilation, logout and shutdown the PC)
  
  
   This includes Calculating dependencies twice of the same set of

   Is it possible, to do ONE call to emerge, which asks (according

   This would save one Calculating dependencies and also reduces writes

  You may want to set this in your make.conf file:
 
  FEATURES=parallel-fetch
 
  What that does, as soon as you start the emerge process, it starts to
  download the needed files.  It doesn't wait until it is ready to work on
  the package to download it.  I've had that set for so long, no idea if
  anything has changed as far as defaults.  I just know it works that way
  here.
 
  If you set that, you should be able to sync, start emerge and when it
  downloads the last files/tarballs it needs, you can then remove your
  internet connection.  You can monitor that with this command.
 
  tail -f /var/log/emerge-fetch.log
 
  Hope that helps.

 Hi Dale,

 thanks for your reply ! :)

 I know of that flag, but it does not exaclty what I want.
 It parallelizes compilation and downloading.

 How can I exactly determine, that the last file has been
 downloaded without watching the monitor all the (because
 these are embedded systems: long) time?

 Best regards,
 Meino








You can disable this feature, so compiling will start when everything is
fetched. I'm not sure weather portage has some post-fetch or pre-build
hook, with one of these you could send a shutdown message from the embedded
system to your PC.

 Did you try suspending using the echo command I mentioned earlier?
 Yes, it seemed to work (just starting up again didn't).

 You can set the resume partition in the kernel. Might be an option.
 Okay, so I changed my kernel command string from root=/dev/sdb2 to
 root=/dev/sdb2,resume=/dev/mapper/g-SWAP.

In my menuconfig I have a space separated list, not comma separated.
So I guess the boot failure is, that the kernel can't find the root
partition /dev/sdb2,resume...


 Then typed your suspension command again, now the system isn't booting
 up anymore: kernel prints trace.

Maybe you need to pass the resume-partition parameter to the kernel in the

You can boot normal with this parameter set and not hibernated

 You search in google and do a ton of clicks, this is so OT. and there

 Windows XP has a build in Remote Desktop but:

If you want to use Windows RDP you can try freerdp, which is a Linux

 Hi Randolph,

This is possilble with screen. yust start a screen session in your script
screen -dmS SessionName

screen -S SessionName -p 0 -X stuff $program\n
where -p gives the screen window number

 Right. heartbleed does not directly affect openssh, but openssh uses
 openssl and it's good practice to keep the shared libraries on-disk and
 the shared libraries in-memory in sync.



 How is OpenSSH not affected?

 emerge -uv1 `equery -q d P`

 Is there an easy way to do so without resorting to shell/python scripting?

lists all packages in short for that are installed and have P in their

 You can't change the owner as FAT doesn't have a concept of owner, so
 it's simulated at mount time. You can't change it at runtime.

 To change it you have to umount the device and remount it using the

 I don't think it has anything to do with FAT.
 Everything was working just find on my system before upgrade.

my first guess would be that the firmware for this device was not

something like could not find firmware, try installing linux-firmware

Re: [gentoo-user] re: emerge --depclean [gentoo-sources]

[Randolph Maaßen]

Hi,

2013/9/21 Alexander Kapshuk alexander.kaps...@gmail.com:
 emerge --depclean wants to remove the gentoo-sources for my old kernel
 [sys-kernel/gentoo-sources-3.8.13] which I want to hang on to for the
 time being.

 Is there a way to instruct emerge not to remove them?

 emerge(1)
 Packages that are part of the world set will always be kept. They can be
 manually added to this  set  with  emerge --noreplace atom.

 If I understood the instruction above, 'emerge --noreplace
 sys-kernel/gentoo-sources-3.8.13' should have added 'gentoo-sources' to
 /var/lib/portage/world_sets, which it didn't seem to do.

No, this it the wrong file. the file /var/lib/portage/world is THE
world set, it contains all packages you emerged manually (and with
--noreplace).
The file /var/lib/portage/world_sets can contain the name of other
sets that should be included into the world.


 box0 src # emerge --noreplace sys-kernel/gentoo-sources-3.8.13
 !!! 'sys-kernel/gentoo-sources-3.8.13' is not a valid package atom.
 !!! Please check ebuild(5) for full details.


 box0=; ls -l `pwd`/world*
 -rw-r--r-- 1 root portage 920 Sep 20 20:45 /var/lib/portage/world
 -rw-r--r-- 1 root portage   0 Sep 20 20:45 /var/lib/portage/world_sets

 Or is it a matter of defining something like this:
 CONFIG_PROTECT_MASK=/usr/src/linux-3.8.13-gentoo
 in /etc/portage/make.conf?


 Any pointers would be much appreciated.

 Once I decide I no longer need 'gentoo-sources-3.8.13', would it be
 enough just to remove the corresponding line from

emerge --deselect atom

Re: [gentoo-user] which VM do you recommend?

2013/7/30 Helmut Jarausch jarau...@igpm.rwth-aachen.de:
 Hi,

 I've been running a Windows 7 (professional)guest  with Virtualbox on my
 GenToo system for some years.
 But recently I have a broken network either due to Virtualbox or due to some
 (automatic) Windows updates.

 The situation is more than strange.

 Sometime using a backed up Virtualbox image the network seems to work but
 only for
 a very short time (some minutes?)

 Windows error analyzing tools don't see any network problems but it does not
 work.

 Trying ping -n 100 IP  only a few packets come back but with a large delay
 (40-50 times
 larger delay compared to ping on the GenToo host)

 I've tried the most recent Virtualbox 4.2.16 as well the oldest one (in the
 tree) which is 4.1.26

 So probably it looks best to me to change to a different (free) VM.
 What do you recommend?

 Many thanks for a hint,
 Helmut

Hi,

I'm using qemu-kvm for hoisting a Windows 7, but always typing the
long commandline is anoying, so I wrote a little script to start the
VM. I recently switched to libvirt and virt-manager, which do the
commandline work for me, and creatting new VMs or starting them is
quiet easy. This system also supports running the VM in background, if
this is important to you. It needs a couple of kernel modules to work,
but emerge will promt to you what it needs.

I'm not on my gentoo machine at the moment, so I can't provide you
details on USE-flags, but I can say I have the QUEM_TAGET varables set
to i386, x86_64

I came across the topic of SSD writes when setting up my laptop with

on SSD a good idea? At some point I found this at ArchWiki page about
SSDs[1], but I don't know how up to date or correct this is.

A 32GB SSD with a mediocre 10x write amplification factor, a standard
1 write/erase cycle, and 10GB of data written per day, would get
an 8 years life expectancy. It gets better with bigger SSDs and modern
controllers with less write amplification.

Now I have /var/tmp/portage on tmpfs and a swapfile on the SSD, but I
think the drive will last for the next years so i don't have to worry
much about it.

 * echoing setterm -blank 0 to the dev/ttyXs
 * xset s off

 A kernelsetting for this seem to have existed in older kernels, but

 All methods have failed.

 Does anyone know of a way to just keep the screen on?

 Thanks,

I have in my openbox autostart.sh xset -dpms s off. this disables the
sceensaver (as you tried), but also turns Energy Star (DPMS) features off.
So no power management turns off the screen.

 On 2013-07-01, Grant Edwards grant.b.edwa...@gmail.com wrote:

  I've just recently run into a problem where sometimes when a machine
  boots, the kernel can't find init.  This appears to be because my grub
  configuration line says root=/dev/sda5 and _sometimes_ the drive
  that contains my root partition is sdb instead of sda. AFAICT, for the
  past 30 years the linux kernel was 100% consistent in the order that
  hard drives were labelled -- but recently that has seems to have
  changed.

 I still haven't figured out why my drives suddenly started getting
 discovered in varying orders.  I think that the SATA drives are always
 in the same order with respect to each other, but sometimes the
 external firewire drive gets discovered before the SATA drives and
 sometimes after the SATA drives.

 It looks like my options are:

  1) Keep hitting the reset button until it works.

  2) Unplug or power down the firewire drive when booting.

  3) Set up an initrd for the sole purpose of finding the actual root
 parition via filesystem label.  [I find this idea rather offensive.]

  4) Build the firewire drive as a module instead of building it into
 the kernel.  That would delay the discovery of the firewire drive
 until after root has been mounted.

  5) For the drive with the root parition on it switch from a DOS
 parition table to a GPT partition table and use the
 root=PARTUUID=whatever kernel option.


You don't need to switch to GPT for that. I have a DOS partitioned disk and
blkid prints the LABEL and UUID for each partition.


  6) Fix the kernel so it can find root by looking at filesystem
 labels.

 Number 6 (fixing the kernel) is The Right Thing To Do(tm), but it's a
 bit out of scope for the momement.  The early code in the kernel
 obviously knows how to read partition tables and also knows about the
 relevent file system, so I'm a bit baffled why it can't look at the
 file system label.

 Changing the firewire driver to be a module is probably the simplest
 solution, but it's a kludgy work-around for what is, in my opinion, a
 kernel bug: if you are going to require people to specify an absolute
 disk drive index for the root partition, then you'd better index
 drives in a consistent order from one boot to the next.

 Switching to a GPT partition table sounds like the cleanest solution,
 but I need to figure out if the grub (legacy) ebuild includes GPT
 support or not.  I know it's supported by grub2, but I don't really
 feel like switching to grub2 ATM.

 And you can pass those values to the kernel via  the root= parameter?


Yep.
The G in GPT just means that the type of the partition is stored as

 No, blkid does not print a PARTUUID value with an MBR. In only prints
 UUID values, which as you noted, are _filesystem_ UUIDs.  If you
 want to use a filesystem UUID to locate the root partition, you need
 an initramfs/initrd which contains an 'init' program that finds the

 does a root_pivot.

 A delete on an SSD is a very expensive operation, to my mind it seems
 completely unreasonable to think that Windows would try and clear many
 tens of GB just because it trashed a partition table. It would take
 _hours_ to clear those blocks.

 By far the easiest route would be to just do what is done for spinning
 disks - write the partition table, leave whatever junk is in the cells
 intact until the partition is formatted and actual data is written to
 the fs.

 As your results show, this is indeed what did happen.

Ok, let me sum up what I understood about the working of SSDs, please
correct me if I'm wrong at some point.

- The SSD stores what internal cell is allocated as a sector for the block
device representation on the SATA port.
- When a file is deleted the file system marks the block device sectors as
free and sends the TRIM command to the SSD and the SSD really frees the
underlying cell / breaks the cell - section allocation.
- Some SSDs have idle TRIM as described in http://en.wikipedia.org/wiki/TRIM to
use the advantage at systems that doesn't have the file system option
- A write operation can write to sectors which are not TRIMed jet

- When some program overwrites the partition table the sectors of the
partition aren't touched, so the SSD must be aware of the partition table
to trim these sectors
- A new partition can be formatted without trimming the sectors

- So when creating a new partition on the same sectors used before, the
sector cell allocation in the SSD is still the same, and no data is lost,
except the SSD is aware of the partition table to know which sectors can be
TRIMed

[gentoo-user] Recover on SSD

[Randolph Maaßen]

Hi,

I have a SSD in my laptop and I am running Win7 and Gentoo in Parralel. for
some purpose I needed several Partitions so my base system was lying on
sda10, on an LVM-PV. Today my Windows refused to start and during recovery
its diskpart must have deleted the information about the 10th partition on
the disk, containing my main Gentoo system. Recovery failed, but
sysrescuecd still works :)

Now I'm concerned about the rescueing of the partition on the SSD, is it
the same way as on HDDs and are the same memory-parts of the SSD used? Or
is the partiton gone forever? And when I recreate a partition, will the PV
with the data still be there and readable?

 You could try Testdisk[1]. It may help. The data on a SSD is not
 necessarily stored linar so it's not said that a new partition is using
 the same memory cells as the old one. Even if it is, you'd lose any
 information about directories or files (names, dates, accessrights and
 so on).
 You should definitly try to minimize writes (ideally there would be
 none) since they can corrupt data. For a HDD I'd advise to create a copy
 using dd but from my understanding of SSD technology it's not
 guaranteed to copy the right (now unused marked) blocks.
 If you can't recover the old partition information I'd say you lost your
 data unless you are willing (and there's no guarantees either) to pay
 substantial amounts of money to specialised services (substantial as in
 most likely  1000 EUR).

I dd'ed the SSD onto an external drive and worked at first on the image

For the partition:
Yes and no. You have to create a sepearate efi partition (type: ef; fs:
fat32) but there is no need to keep it mounted while th system is running.

For the boot loader:
I have no experience wit elilo, but grub 2 works well if you like the menu
and autoconfig it provides.
There is a 3. Way loading the kernel: efi_stub. If you compile the
commandline in the kernel and you don't use an initrd enable
CONFIG_EFI_STUB in the kernel and copy the bzimage to your efi partition as
an .efi file and announce the kernel image instead of grub2.

The arch linux wiki page was verry helpfull for me.

Ps: be sure to test your kernel before using efi, there are reports that
the firmware gets brickt in some cases. (It came out on samsung laptops)

Re: [gentoo-user] ntfs-3g problem (I suppose) - locking system

[Randolph Maaßen]

2013/3/15 Francisco Ares fra...@gmail.com

 Hello.

 During some months now, this machine was (and still is, sometimes)
 suffering from a strange progressive lock down. It always has begun with
 the web browser, passing to the whole X environment, and finally I could
 not even use a console.

 After several trial and error actions, as no log entry could give any hint
 on what is going on, it seems that I found something consistent.

 This machine is a dual-boot Linux/Windows, as my wife once in a while
 needs to work on a Windows O.S. .  The lock down starts when she saves a
 file received by e-mail in a ntfs-3g mounted partition, so that file would
 also be accessible whenever she uses Windows.

 The reason why I suspect of ntfs-3g is that when the lock down starts,
 that is, if only the web browser locks, just unmounting (and mounting back
 later) that partition, recovers the web browser functionality. Sometimes,
 when the lock down has already affected the whole graphic environment, but
 I still may use a console, again unmounting that same partition also
 unlocks everithing.

 I have already tried to emerge ntfs-3g with different use flags, but the
 problem persists. Even built a new kernel and re-emerged ntfs-3g after
 that. Now ntfs-3g package is using its own fuse.

 I would really appreciate any hints on what to do or where to look for any
 more information on this subject.  Perhaps I am still looking at an effect,
 and not the cause.

 Thanks
 Francisco

 With NVidia, it is usually a good idea to at least use the latest stable

 keyword the latest NVidia driver that's considered stable by NVidia, not
 by Gentoo. That would be 313.18.

 So update to gentoo-sources-3.7.9 and nvidia-drivers-313.18. And make
 sure you do (as root):

   eselect opencl set nvidia
   eselect opengl set nvidia


 According to nvidia the latest stable certified driver for my card:
 GeForce GTS 450 is: 310.32 (which is in portage)

 I tried it with kernel-3.6.11 it does not work but it works with 3.1.6
 I don't know why?

Hi,

I have just read the thread and recognized that you have the same graphics
card as I have.

I updated my kernel this week to gentoo-sources 3.8.0. After that I tried
to install the 313.18 driver and compilation failed.
So I tried the 310.32  driver and it works perfectly with the new kernel.

[gentoo-user] Booting the Kernel as UEFI App

[Randolph Maaßen]

Hi Guys,

I just got my laptop back from repair, the main board and harddrive are
changed, so bye bye data. I haven't created any data on gentoo, i couldn't
even set up the system before it crashed.

So I'm going to setup a new install, and I have heard that you can set up
the kernel as UEFI application[1]. I have booted the system from UEFI grub2
before, so UEFI works and I know that the BIOS/UEFI has a boot manager.

Has anyone here did this before or is this a bad idea ?

I had to use Windows till about 3 months ago, and I came back to gentoo and
used gnome again. But I didn't feel that comfortable and home, so I tried
kde and some other desktop environments, but these felt even worse. I found
cinnamon and used it with  gdm, what made me happy for a while. But I
couldn't find an easy way to configure this system to my needs. I found no
way to change the gdm background for example. I googled for a couple of
days. So I tried to get rid of gnome, but I have some programmms, that use
it. I use Openbox and slim now, I could configure it within half a day, and
I'm happy now.

By the way, I got used to tabbing terminal.in gnome-terminal, does someone

Hi, when you are dealing with python always remember that the API has
changed between version 2 and 3 so python 3 can't handle python 2 scripts.

So what I think emerge is doing here is installing python 2.7 beside 3.2.

When you add the verbose flag to the emerge command, you will probably see
something like [ NS ] or [ uS ] at the beginning of the python line. The S
stands for new slot, so both version will be installedbecause samba or one
of it's dependency is using python 2 scripts.

Re: [gentoo-user] OT: python, accounting gentoo

[Randolph Maaßen]

2012/8/24 James wirel...@tampabay.rr.com

 Hello

 I'm looking to learn more about Python and it's capabilities.
 Since I have some loose requirements to integrate some financial
 accounting and data collection into an sql
 database, I figured I'd research relevant, existing software
 as well as writing some code in python, to see
 how well I like python. with web, graphics and database
 systems.

 So what I have found on Gentoo is openERP
 Other software (written in python is a requirement)
 not in portage, that I have found so far is:
 GNU Enterprise and Tryton. Any Others?

 So whether  it's a basic (python) based accounting system
 or a full blown Enterprise Resource Planning tool,
 I have one twist as to what the software must eventually do.
 I have  a myriad of embedded devices that provide all
 sorts of machine based data (literally pumps, valves, etc and
 all sorts of sensors) that will also be sending data into the
 database system. I also have a myriad of very questionable
 mathematical models that generate simulated sensor data also
 to be included, monitored and analyzed.


 So I want to find/develop/refine  software
 that is able to collect data from  all sorts of disparate
 sources. To then display it like a normal accounting  software
 package would, but also be able to display some (selective) data
 in some sort of separate, graphical display, so a particular
 parameter(s) could be displayed in a (real-time) graphical gui,
 much like a speedometer on the dashboard of a car, simultaneously too.

 Usually Java, qt4 etc are used to generate the graphical displays
 on a computer screen. Is python viable as a language/tool to also
 create these graphics? If not, what would be a good language,
 that works well with python,  to use to develop either web based
 or display graphics?

 This is an evolving, formative effort, so all input, particularly codes
 that exist, are welcome. Comments on using python, and other ideas
 are most appreciated.



 James






Hi,

I cant tell you much about accounting software, but what i know is that
there are python binding for qt and gtk, just look for PyQt4 and pygtk.
Another toolkit with bindings i I know about is wxWidgets with wxPython.

I'm sure, there are bindings for your preferred toolkit.

 Remove the power supply. Go outside ;) and blow the dust inside away.

 Put the power supply back into the PC again an attach the cables.

 Remove all RAM, carefully clean the contacts, insert as less RAM as
 possible.

 Remove even the HD if it is possible to get into the BIOS
 without any HD attached.

 Remove the BIOS battery, wait at least a day and insert it again.

 Start the PC and go directly into the BIOS. Check the date/time.
 If it shows the current date/time, the battery wasn't removed
 long enough. Check the battery voltage. Reinsert the battery.
 If your board has a BIOS reset: Reset the BIOS.

 Then: In the BIOS enter a page which does something
 (reports continously temperatures for example).

 If this is possible, let the PC run for a
 while that BIOS page and see, whether it
 hangs again or not.

 If all went fine, add ONE component and try it again.
 Add the HD at last to sort out hardware from software bugs...

 May be one of the components and not the CPU or motherboard
 causes the problem and you will be able to identify it by
 this procedure...

 HTH!

 GOOD LUCK!

 Best regard,

  Hi there!
 
  Two days ago, my PC suddenly died, after working fine for half a year.
  I used myrtcwake as usual to suspend to RAM, and it woke up in the
  morning. But after two minutes, the screen went blank and nothing, even
  SysRq, gave a reaction. I tried booting a couple of times again, and
  sometimes it did not even reach KDM. Now, I cannot even run Grub (from
  my USB stick) any more, I only see a GRUB string at the top right,
  then nothing happens.
 
  Booting with SystemRescueCD also freezes sometimes. If not, I can make
  it freeze after seconds by running 'memtester'.
 
  Booting good old memtest86 ran for an hour and only found one error,
  then I aborted, removed three of my four memory modules (4GB each), and
  tried different ones in the first bank. Memtest86 again did not find
  much errors, but froze once. Running memtester after booting from
  SystemrescueCD again makes the thing freeze in seconds. It once also
  froze while being in the BIOs setup.
 
  What could be the problem? CPU, board, or even the PSU? I do not think
  it has to do with bad memory. I removed most of the other stuff (hard
  drives, PCI cards). I have no similar hardware so I cannot simply
  exchange things, the question is what to buy and try. How would you
  proceed?
 
  The fan is still working, the cooler does not become hot, and in the
  BIOS there are not high temperatures begin reported. But one thing was
  strange: I updated Calligra from 2.4 to 2.5 (I think), and it took
  ages, at least 8 hours. I thought there may b something strange with
  the build process of this new version, forcing MAKEOPTS=-j1 and such,
  but still this is very long. But when working with it, I did not notice
  anything strange like sluggish reactions, and videos played fine. But I
  did not use it as much as I normally do, and maybe even when overheated
  and throttled down it would have been fast enough for me to not notice
  this. I watch the syslog normally, but maybe I just did not look
  closely that day, I was busy doing other stuff.
 
  CPUs don't just die, do they? Even when overheating, I think these days
  throttle down, so no permanent harm should be done? So maybe it's the
  board? It looks okay, no bent or leaking capacitors.
 
  This is really annoying. Of course most of my passwords are in my KDE
  wallet I cannot access. There's also Wiki, CVS and Git repositories,
  not needed every day, but still important. And the timinig is very bad,
  I just started my new job the day the problem happened, and I do not
  have much time for this now. Before, I was working at home, so I would
  have had all day to diagnose and try things.
 
  It's an AMD FX-4100 Quad-Core CPU, and an ASRock 880GMH/U3S3 board.

Re: [gentoo-user] Gentoo Installation, Kernel Panic

[Randolph Maaßen]

 Hi,

 After going over the installation instructions and performing the standard
 operations (genkernel etc.), the Kernel halts during the boot.
 http://www.gentoo.org/doc/en/handbook/handbook-amd64.xml?part=1

 I'm attaching the screenshot of what happens…

 I'm not the Linux expert, so don't know how to fix.

Hi,

looks like the kernel can't find your root partition. (VFS: Cannot open
root device sda3 or unknowen block(0,0)).

Please make sure that you configured your grub correctly (which version do
you use?).

On grub legacy (0.9)  edit the file /boot/grub/menu.lst and add the
root=your root partiton parameter

it should look like this
title Gentoo
root (hd0,1)
kernel /boot/kernel* root=/dev/sda2

When you need further help, please post your partitioning and grub menu
entry, grub device names can be verry confusing for beginners.

The more complex idea in my mind is that your kernel is missing some device
drivers for the ide/sata controler.
This should not happen, because you used genkernel.
