[gentoo-user] Dhclient and buggy ISP

[Matti Nykyri]

Hey

I have a following with Telia ISP and their dhcp-server... I'm using 
dhclient to get dynamic IP from ISP and also to update DDNS. When 
dhclient does DHCPDISCOVER the ISP will issue a new lease for 43200 sec 
after a normal DHCPOFFER, DHCPREQUEST and DHCPACK cycle; and the 
interface gets bound to the given address. Now when the dhclient does a 
subsequent DHCPREQUEST, server will issue DHCP with a declining 
lease-time ending at the same time as original 43200s lease. By 
releasing the lease and doing a new DHCPDISCOVER the lease time is reset 
to 43200s. The ISP how ever keeps track of the MAC and will always issue 
the same IP.

When the lease-time of 43200 runs out the default gw stops responding 
and the internet connection dies. The only way to then get it to work is 
to manually start a new discover cycle (ifdown - ifup).

I would like to configure the interface so, that there would not be an 
interuption in network traffic! Because the IP doesn't change, I would 
like to configure the WAN interface to stay up with the IP all the time 
and get dhclient to do DHCPDISCOVER to the ISP to update ISP-firewall to 
let the traffic through for the next 43200 sec. If the IP changes for 
some reason, I would like the dhclient to update the WAN interface.

Would there be a ready way in Gentoo to achieve this? Or anyway :'D

Ps. I hate my ISP :(
Pps. I have other problems too...

Well this is a linker error. This means that you are linking without -lbotan 
flag or the installed version of libbotan.so is incompatible with 
qt-creator-3.6.0

You can fix this by compiling qt-creator without out botan or upgrading 
dev-libs/botan to a version required by qt-creator.

If you have the correct version of botan installed then it might be that the 
linker is unable to find libbotan.so

Based on the error messages it is probably a version mismatch, because there is 
only one kind of undefined reference.

Sunc doesn't necessarily sync everything and if some random files are out of 
sync you either need to update them manually or get a new snapshot. I doubt the 
server/mirror is messed up, but you could try changing that. Downloading a new 
snapshot isn't that big a deal and that should definitely fix everything, so 
why not try that first?

You may also inspect each package and remanifest those that have problems 
(ebuild manifest). If you are certain that nobody has been fingering your 
ebuilds.

Well it's not. It just checks all the manifests and complains about errors. It 
doesn't affect the building of 1.23.1-r1.

If I were you I'ld download the latest portage snapshot. That should take care 
of any remaining issues. Is your portage upto date?

Syncing and getting a new snapshot is a bit different. With a snapshot you get 
a new clean start. Download it and unpack.

After that check that your portage package is upto date (emerge -av portage).

I rsync with rsync.europe.gentoo.org and with me the manifest with busybox is 
in order.  Size for .ebuild is 8493 and the Manifest has the same size. 
Also the hashes match.

I hope you get it right :)

Don't panic!

There is a simple solution to this... Kernel developers have foreseen this 
problem already! In your situation your graphics hardware is not getting 
the EDID of your display, decause it is physically not connected to the 
monitor when you boot up. See /Documentation/EDID for details.

Set DRM_LOAD_EDID_FIRMWARE=y

You can use x11-misc/read-edid to fetch edid from your monitor: 
get-edid > your_edid.bin. Or you can use modedebug in xorg.conf and get 
edid from Xorg.0.log

Save the edid from your monitor to /lib/firmware/edid/ and include in your 
kernel commandline "drm_kms_helper.edid_firmware=edid/your_edid.bin". You 
can also set your video mode in comman line "video=DVI-I-1:1024x768@85". 
The names for your connectors are found in "/sys/class/drm/*/status". 

https://wiki.archlinux.org/index.php/Kernel_mode_setting

These work with kernel mode setting. If you are using some proprietary 
driver, see the documentation of that driver. At least with nvidia you 
can set your custom edid in xorg.conf "Option CustomEDID DFP-0:/your_edid.bin"
and force monitors to be detected as connected at all times 
"Option ConnectedMonitor DFP".

 Does qemu actually support passing a whole graphics card? Never tried it.

Yes it does. For examlpe if you have a windows client and pass the card to it 
the client can utilize directx and you get nearly native 3d performance in the 
games within the client. In that case the client owns the graphics card and the 
has to have another one should it require one...

Re: [gentoo-user] [OT] How to add library to dynamically linked executable?

 Is there any way to add a library to the list of libraries required by

 I have an executable (let's call it foo) which was written and built
 by somebody else [I don't have sources].  It requires the librt to run
 on one particular platform, but librt isn't in the exeuctable's list
 of libraries.  [I'll skip the story of how it ended up this way. It
 will be fixed with the next version of that application.]
 
  # foo
  foo: can't resolve symbol 'shm_open'
 
 If I run it like this, it's fine:
 
  # LD_PRELOAD=/lib/librt.so.0 foo
 
 Is there any way to fix the ELF executable file to add librt.so.0 to
 its list of libraries?
 
 I'm aware I can create a shell script that does this:
 
 #!/bin/sh
 export LD_PRELOAD=/lib/librt.so.0
 exec foo
 
 What I'm wondering about is whether there is a way to fix the ELF
 executable file itself so as to add librt.so.0 to its list of shared
 libraries.  I've found chrpath(1), but it only changes the search path
 used to look for libraires, not the list of libraries themselves.

The question you have has multiple solutions to it... Doing it as it should be 
done is only possible if you have all the needed object files at hand.

A ready made tool that just adds a shared library to an executable does not 
exist. But i believe you have a hexeditor, that is able to do it ;)

I have tryed many of these options and it is quite tricky if you don't have the 
ELF object-files. There are various tools for you available objcopy etc...

One option is to make a library that load two libraries e.g. librt and another 
library needed by the executable. Then hexedit your executable to load the new 
library you created and it will load the two libraries needed.

Also you can write a c program that modifies the elf executable, but i don't 
think you need to for this problem.

 There's an option CONFIG_RTC_HCTOSYS on the kernel to do it automatically. I

Don't store hwclock in localtime. It is a hack and you are asking for trouble.
Just store it in UTC. That way the worst mishap is that it gets 1 second to

 When I do a control-right-click on an xterm to manipulate fonts, the
 xterm crashes.

X server abjusts font sizes according to the DPI value. The DPI value it 
calculates might be wrong though: bad EDID most likely. Set the DPI value in 
you Xorg.conf file to make the fonts in constant size.

  One of the nice things about having multiple machines, is that I still
 had another machine with the old fonts.  For a few years, I've preserved
 a copy of /usr/share/fonts from that machine as fonts_do_not_delete.  So
 each time fonts are updated on my machines, I rename /usr/share/fonts
 to /usr/share/fonts.borken and copy the fonts_do_not_delete directory as
 /usr/share/fonts.

CONFIG_PROTECT the directory or make the fonts immutable so they don't get

 Hi,
 
 how would you go about creating a web page from either a CSV file or a table 
 in a mysql database which presents the data to a user and lets them edit some 
 of the data, preferably with the ability to use formulas like you can in a 
 spreadsheet to do some calculations on the fly?

A php script that does that kind of table drawing is really easy :) Editing the 
content is harder... You have to think how you wan't to do it. Htlm has its 
limitations :/

 Once editing the data is finished, it should all be saved to a table in a 
 database or as a CSV file.

Design it so that you know for certain which cells the user has edited so you 
don't need to overwrite the entire table even if the table has changed in 
between.

Many things depend on the size of your table. Raw non-relational database is 
really easy to interface even with html. Excel can do a table with 2^16 rows 
and few hundred columns. With mysql you can easily do like a million rows :) 
design the database so that it has a separate value for the user typed cell 
content and another for the displayable result of the content.

 Is there some php script or the like which can do this or get me started?

Well i would never use HTML for real work, it is for free-time (facebook etc). 
Qt has has a really good frontend for working with mysql table. It is fast and 
supports getting rows asynchronously in the background and in the specified 
range. With a qt frontend the gui looks much better and unified than with a 
web-browser.

 Actually systemd's poweroff should be on /usr/bin or /bin but if you got it 
 there you shouldn't have got the command not found error so something is 
 messed up with your system. Post the output to the folling
 
 ls -l /usr/bin/poweroff
 ls -l /bin/poweroff
 ls -l /sbin/poweroff
 ls -l /usr/sbin/poweroff
 
 Only one of them should list something and it should be a symlink to 
 systemctl.

From previous messages by the OP I recall that he is using OpenRC.

 You don't need those. It sounds like you somehow got both sysvinit and

 I can reboot the system when I am a user by Ctrl+Alt+Delete.
 The user can reboot the system, but can't shut down ?  Strange
 The thinking is that you can unplug the machine
 or press the hardware reset or power button or flip the PSU switch ...
 Preventing a ctrl+alt+del reboot does not add anything to security.
 Security doesn't apply to users with physical access to the machine.
 However, this is just a default. You can easily disable reboot
 on ctrl+alt+del by editing /etc/inittab and commenting-out this line:
 ca:12345:ctrlaltdel:/sbin/shutdown -r now
 
 Testing my single-user box with the above line in  inittab ,
 I find that if I enter 'A-^Del' , I exit X to the raw terminal ;
 another 'A-^Del' then reboots the box.  If I enter 'shutdown -r now' as user,
 I get shutdown: you must be root to do that!.  'cd /sbin ; ls -l shutdown'
 shows '-rwxr-xr-x 1 root root 23192 May 17 2014 shutdown',
 so that behaviour arises from the shutdown script, not the permissions.
 
 The 1st effect is explained in  ~/.fluxbox/keys  by
 # exit fluxbox
 Control Mod1 Delete :Exit
 
 However, the 2nd effect is not explained so easily :
 'A-^Del' reboots when entered at a raw terminal,
 but 'shutdown -r now' does not, yet the former is defined as the latter
 by the line above in my  /etc/inittab .
 
 The cause seems to be that 'A-^Del' is intercepted by 'init' (Process 1),
 which is owned by root, but 'shutdown -r now' is heard by Process 910
 -- 'bash' running in the raw terminal, which was started by 'init' -- ,
 which is owned by my user.
 
 So the behaviour is explained, but following my earlier msg,
 which advised to follow proper Unix principles,
 I should comment the 'A-^Del' line in  inittab :
 if the raw terminal can't react to 'su', it won't react to 'A-^Del' either,
 so there's no justification in terms of escaping from an emergency.

When you press ctrl-alt-delete kernel recieves  it and sends it to the program 
that has grabbed the keyboard. If this program doesn't trap the sequence it 
goes to the parent program. Like if you are running a terminal in X it first 
goes to the shell then terminal and then to X-server.

Now usually X traps that and performs what ever action is configured. If you 
set X not to trap the key press it goes all the way down back to the kernel. 
When kernel receives it it generates hang-up signal and sends it to the PID 1 
aka init. And then executes the command in inittab.

ca:12345:ctrlaltdel:/bin/echo shutdown

And then:
kill -HUP 1

Will print shutdown to your console. If you write a small program that traps 
ctrl-alt-del and run that in terminal, the server will not reboot :)

 pressing the reset button is far worse, since there's no clean shutdown,
 unmounting filesystems after flushing caches, etc.
 
 Yes : that's forced only when the keyboard ceases to respond.
 
 Because of that, the default of allowing ctrl+alt+del for local users
 makes more sense than disabling it.
 
 That doesn't follow : if you have multiple users,
 you don't want some rogue user rebooting randomly ;
 it makes sense only as a convenience on a single-user system.
 It seems to be the default behaviour of 'inittab'
 -- there no comment saying I set it myself, which I would have added -- ,
 which is not appropriate for Gentoo systems in general,
 some of which are undoubtedly multi-user.

On a multi-user system only the user sitting on the local terminal can press 
ctrl-alt-del and reboot the machine as he could also hit the server with a 
sledge hammer :)

[gentoo-user] Nouveau KMS Xorg-setup with multiple screens

[Matti Nykyri]

Hello

I have problems. I'm migrating from nvidia proprietary driver to nouveau driver 
because I wan't utilize KMS.

The server is connected to two separate displays in separate rooms. The first 
display is showing tv programs and mostly runs @50Hz frame rate. The second is 
displaying movies and hence runs at 23.97Hz. The programs sync to VBLANK! 
Nobody can stand the tearing of video without it! With nvidia and UMD I had two 
screens and everything worked perfectly.

So with this setup it's necessary to have two screens, right?

Is it possible to have 2 screens with KMS and nouveau driver?

It has WPS setup. Some drivers with this have huge security hole that even if 
you disable WPS it remains on. If WPS is on there is practically no security in

 I have to try to run it 0660? Will it be less security risk?

Well 0666 = 666. The reason it now worked is because you logged out and then 
back in. This is becaus login program only reads the /etc/login.defs-file when 
you login.

With mode 0666 every user on your computer can read everything (every 
character) you have in your screen (so not much privacy). If you set:

TTYGROUP utmp
TTYPERM 0660

And have:

-rwxr-sr-x root utmp /usr/bin/screen

Everything will also work and you have more privacy.

When /bin/login us run it changes ownership of the tty to the user who logs in. 
Su -l does not do this. That is why the screen doesn't work. ConsoleKit is the 
program that is responsible for many of these permission changes. Do you have 
that installed?

I have the same NIC as you do: RTL8111/8168/8411. It is under 1 GB ethernet

There is another option though and the portage provides ebuilds for it. You can

This matter has been already addressed in the list so you could search the

Boot into the rescuecd
Open your first disk with gdisk or parted:
gdisk /dev/sda

List partitions (penter in gdisk and print in parted)

Find a partition of the type EF00. That is your UEFI boot partition. Mark down 
the number of that partition. The number most likely 1.

If you didn't find EF00 partition search the next disk (sdb).

Mount your boot partition (in my setup it is sda1):
mkdir /uefipartition
mount -t vfat /dev/sda1 /uefipartition
nano /uefipartition/loader/entries/gentoo.conf

Just edit and save and you are done. If you have everything setup as in the 
wiki (http://wiki.gentoo.org/wiki/Gummiboot) this will work. Neil gave the same 
instructions... This is just a bit more detailed.

I like to always keep grub installed because it is like swiss army knife for 
booting. You can always get a shell and find your lost kernel image. Even if it 
is still in /usr/src... So you kind of like never render your system to an 
unbootable state. Nor would need to use rescue cd. And you can boot windows, 
memtest, chainload etc!

This was discussed earlier on this list... Actually what syslog-ng produces is

[gentoo-user] VM running windows as a guest

I am new to virtualization and would like to receive few notes on things before 
starting. I clearly see that a lot of you guys are quite pro's with that.

I would like to run gentoo and windows on my workstation at the same time so 
that i could get rid of rebooting my system when switching. Ideal solution 
would be to have X-windows in vt7 and windows 7 in vt8. Is that possible?

Based on what i have learned i think my best solution is to run gentoo as host 
using KVM and qemu for the windows guest. I have the windows installed on my 
hard-drive. Can I use that image for the guest if I run it in HVM mode?

To run serious applications in windows I probably need paravirtualization. Can 
I modify the old windows image or is it better to begin with a fresh install to 
get virtio drivers to the windows?

Here just few thoughts that i have in mind...

I had a similar challenge. But it is quite easy to overcome. After the backups 
just untar the latest stage3 to your root filesystem. Then sync portage and 
emerge world with a empty tree and keep-going flags. It should get it done 
mostly. Few packages might fail to merge, but after the world update the list

 Hi,
 
 after a few more non-booting-systems and backup-reinstalls I think
 I know whats the reason is...but by I dont know how to get out of it:
 
 The system becomes inaccessible if I do an env-update and reboot.
 
 Reason for that are binaries, in which the path to the old gcc is
 hardcoded. With the sdcard mounted I checked that with my PC:
 I did a 
 
grep -r '\/usr\/lib\/gcc\/armv7a-hardfloat-linux-gnueabi\/4.7.3'
 
 on ALL files of the sdcard and found thousands of hardcoded links
 to the old gcc inside binaries...
 
 The new gcc installed but not doing env-update implies that any
 further compilation will link to the old gcc.
 
 Doing env-update implies a system which will not survive the next
 reboot.
 
 What now?

If i understand your situation correctly, do:

gcc-config to set the new version
env-update
logout
login
emerge --deep --update world
emerge --depclean
revdep-rebuild

This will take a long time but will get your system working again. If you don't 
wan't to do that you can of course tweak the libraries with binary tools. That 
is easy if you know what you are doing.

To prevent this in the future always before world update, update gcc and glibc 
first if tere is a new version available. Gcc-config is crusial after you have 
installed a bew version of gcc.

What you need is DVD-author. These are rare now a days. Here is a list:

I've been using Q DVD Author successfully for few times in 2011, but 
DVD-authoring wasn't at least back then fully automatic stuff.  And also dvd's 
are becoming obsolete. You just create the menu structure and then the 
authoring program produces iso-image (videots.ifo/vts_0-0.vob). The 
'DVD-language' kind of primitive (qbasic/any script).

Because the temperature of the laptop in the freezer will always be above dew

If I were you, I would setup your pc to do cross-compiling of your arietta's 
packages and build them into binpkg's. This could be all stored on the pc and 
accessed via nfs for example. Then the first dependency calculation would be 
done on the pc to build the packages and the second on arietta using only 
binary packages.

You should keep /etc/portage, /var/lib/portage and /usr/portage on the PC and 
not modifiable from the arietta. This way you only need to install the run time 
dependencies to the aritte. And install from bin pkg is really fast. 

 Another alternative would be to use a USB to ethernet adaptor on the
 embedded board and connect it directory to your router.

This also sounds good. Or setup server which has the usb and is always on.

Arietta A eth0 - usb - pc - usb - Arietta B eth0

A lot easier setup. Nothing extra needed. Just route command on PC!?

 You're probably better off not using the in-kernel NTFS and using ntfs-3g

 Hi,
 
 another sigh from an Arietta adventure...
 
 I sintalled Gentoo on an Arietta G25
 (http://www.acmesystems.it/arietta).
 
 For this I used Robert Nelsons Kernel for armv5tel platforms,
 which boots fine (using at91bootstrap, no U-Boot). 
 
 But: Shutdown (as recommmended by acmesystems shutdown -h -H now)
 REBOOTS the system instead of powering it down.
 
 The hardware is not to blame: Using the original Debian rootfs
 and the kernel 3.16.1 (Robert Nelsons kernel is 3.17.3.) the
 powerdown works fine.
 
 Firstly I blamed the kernel...but when using the 3.16.1 kernel
 and the Gentoo rootfs the problem remains.
 
 Then I copied the Gentoo shutdown to the Debian rootfs, boot that
 and tries to shutdown the Debian Linux with it.
 shutdown cries no /dev/initctl adn shutdowns the system only for
 rebooting it.
 
 Ok...seems to be the shutdown executable.
 
 I copied the Debian shutdown to Gentoo and tries that:
 The systems reboots.
 
 Slowly but surely I begin to think, that I dont understand anything at
 all of
 It would be relly good news, 
 that...
 
 man shutdown on the Debian image informs me, that the manpages
 were not installed (embedded system...). Shutdown --version gives
 a short help of the usual options...but nothing more.
 
 What is the difference here? 
 Isn't it, that all shutdown applications only send some instructions
 to the kernel and the kernel is the main actor in bringing the system
 down?
 
 Is there any shutdown guru ;) out there, who is able to shed some
 light into this problem ? :)
 
 Thank you very much in advance for any torch send into my direction!

 Hi Dale,
 
 The Trouble shooting FAQ*)  by acmesystems explicitely say shutdown -h
 -H now (and it works with the Debian rootfs)...but I will try the
 other shutdowns and will see, what happens,
 
 Best regards,
 Meino
 
 
 
 *) http://www.acmesystems.it/qa
 
 Looking at the code for sysvinit, all shutdown  does is set some environment 
 variables and switch runlevel. The actual shutdown is done by halt and it's 
 done through the reboot system call with RB_POWER_OFF.
 
 So, since you said the Gentoo system doesn't work even with Debian's kernel 
 and the shutdown, then it must be that either Debian has a different halt, or 
 more likely your Gentoo system calls halt with different options. So check 
 your 
 inittab on Gentoo and make sure it calls halt in the same way.

Hi meino

The thing is as Fernando pointed out:

Kernel powers off the hardware and a system call is used to instruct kernel to 
do so.


Test your system. Perform a system call to shutdown the board. As you perform 
this system call the arietta will instantly eighter boot or shutdown. See 
system call man page to see the list of available system calls. This way you 
can make sure the system works as expected...

When you have found the right system call, then you need to make init call that 
system call as the last command in run level 0.

 No. It happen every time I boot into linux. Gentoo or Arch.

 Its a realtek chip .
 The bug that you mentioned is related to linux driver or windows driver?
 

I have realtek R6168/6111/6169 NIC. It works in Linux with realtek's driver not 
with the one included in kernel. Windows fails to initialize the NIC properly 
when I reboot from linux to windows. When NIC is reset by recycling power 
windows will be able to initialize it. Downgrading windows (7 64bit) dirver to 
an ancient one fixed the problem. The up-to-date realtek driver didn't work 
correctly. 

lspci -v

You can check what driver kernel uses for you audio. Also the bug can be in 
alsa. The ways of alsa quite complicated... You are using alsa right? What 
error message does alsa give when you try to play audio?

 binpkgs.
 
 You are talking about what happens to binpkg you already have, he is
 asking how to get binpkgs in the first place

You also have a tool called 'quickpkg'. With that you can make binpkgs out of

good tool for you if you have not made them in the first place.

 
 so you can still emerge -K old-apps/package

 Ah! By the way...I was astonished to read, that the digits of PI
 are called random on the one hand and on the other hand there is
 a formula [1] to calculate a certain digit of PI without
 calculation of the previous digits... Calculated random? Are
 nature constants the purest form of PRNGs ??? ;) (Quantum physics
 is everywhere... ;;))
 
 [1]:
 http://en.wikipedia.org/wiki/Bailey%E2%80%93Borwein%E2%80%93Plouffe_formula
 
 
 The sequence of digits that make up pi are a random sequence - you
 can analyze the order any way you want and you'll find no inherent
 pattern.
 
 Actually, the sequence of digits is most definitely *not* random.  If
 the sequence of digits is written any other way then the value is not
 Pi.  Hence the sequence is unique, not random.
 
 I think what you are grasping for is that the frequency of distinct
 digits tends to be uniform: 0's occur as often as 1's as often ... as
 9's.  Note that the as often as operator is really approximate for
 finite sub-sequences, but is asymptotically accurate.
 
 Moreover, this is the same in any number base: the binary
 representation has 0's occurring as often as 1's; the ternary
 representation has 0's occurring as often as 1' and as often as 2's;
 etc., etc.
 
 Such numbers are called normal.  It was a poor choice of name, but
 we are stuck with it.  I would have called them digit soup numbers
 - -- an oblique reference to alphabet soup.

Well all the digit of pi can be compressed to the following:

=pi();

If you have the infinite series that calculates the digits :)

 However, any given digit in the sequence is 100% predictable, as
 you just showed :-)
 
 Randomness has got to be the second most mind-boggling thing out
 there, first being quantumness (that's not a waord, I just made it
 up. You you should get the meaning OK from context ;-) )
 
 I would say that probability theory is more mind boggling, as it
 underpins much of quantum theory.  But, as someone who majored in
 probability theory, I might be biased. [Incidentally, there is a small
 statistical joke in that last sentence.]
 
 Getting back to Meino's original request, one of the optimum
 compression algorithms for this would be custom Huffman encoding.  To
 do this the algorithm requires that all the data (i.e. digits) be read
 and a frequency table built.  The only problem is that to read all the
 digits of Pi could take rather a long time. ... :-)

That would take infinite time :)

 The art of computer programming and his MMIX alogrithm

 What you are considering doing is quite a challenge. What kind of 
 coordinates does your gps module give you? The gps system works with 
 cartesian x y z coordinates. Then these are usually displayed to the user 
 in WGS-84. This is a quite hard mathematical problem (differential 
 elliptical problem). Usually is done by your gps receiver and is 
 approximated. GIS libraries have these functions built inside. Distances 
 are easier and faster to calculate in cartesian coordinates. You need to 
 calculate distance because coordinates from gps will never coincide with 
 any address.
 
 Open street maps provides a very good start, but addresses have great 
 differences in different countries. For example google misses addresses 
 quite much depending on where you are searching. Getting the address right 
 requires good locality from the program. Addresses and roads are vector 
 maps. The fastest way to get address is to have the vector map of the 
 world and then calculate distance to the closest address. The database 
 will be huge :)
 
 Maps are usually raster pictures which have some projection. When you 
 display them you can use 3d or 2d visual. In 3d (like google earth) you 
 draw a sphere (or oblate spheroid) and draw textures on top of is to the 
 right coordinates. In 3d everything needs to be converted to cartesian 
 coordinates. Or in 2d you decide a projection and then convert the 
 projection of your maps to this projection. After that it is just easy 
 drawing. GIS libraries contain all the needed tools for these operations. 
 There are a few of them with open source license.
 
 I have been doing some work with opengl 3d drawing maps. Good luck your 
 project is quite big but it is sure very much fun :)

 But back to your mail:
 The GPS module I plan to use is this one (by Adafruit, Lady Ada):

 From there (see link list on the left) you can also download

 Nice... MicroTek chipset. Quite easy to use.
 
 I will not use this thing as a driving assistant or navi (is this

 time /I am/ serious! :) )
 
 Its more like a GPS data logger. I plan to copy the gathered data on 
 my PC later and I will try to draw them onto a map.
 May be the results proof later, that I am able to walk through walls
 and hovering over the face of the waters...;)
 
 Ok. This is easy... You just need some maps... openstreetmaps are good
 for that. From the MT3339 you get NMEA messages and WGS-84 coordinates. 
 I would suggest displaying your results in 2D. For germany Lambert 
 conformal conic projection is good choice. In this projection all angles 
 are true and sreight lines are great circle routes. Just convert the 
 maps to this projection and convert your coordinates to Lambert false
 easting and false northing and you will have cartesian coordinates that
 are easy to draw. Even excel is able to draw this in real time :) I don't
 see where you need the address resolution.

 Openstreetmap is a good bet.

Hi,

Just wanna say few words to clarify few things about bootstraping. If you know 
what you are doing, this all is very simple.

What you need for a working system is a working root filesystem that contains 
all the scripts, modules and executables. A minimal cd contains this. You could 
also use stage3 tar ball.

Then you need a working kernel image and possibly a initrd. There is a working 
kernel on minimal cd.

All begins with boot loader. That loader is loaded by BIOS first. Then boot 
loader starts executing and loads kernel with right parameters. Kernel takes 
over and loads rootfs and so on.

On normal disk (USB, sata, ATA, SCSI (and DVD i think)) you have a normal MBR 
(first 512 bytes of disk) which BIOS loads to 0x07C0 address in memory and 
starts executing. So just install boot loader (like grub) to the beginning of 
the disk and it will boot. With right commands/config you can load the kernel 
correctly and boot.

CD is different. BIOS can't read ISO file system. For CD boot you will need to 
create image of a floppy-disk and install your boot loader into that image. The 
boot loader has to have drivers to read the real ISO file system so that it can 
load the kernel into memory and boot. Because of this a plain cd isoimage is 
unbootable although all necessary stuff is there. It is easily arranged so that 
it becomes a bootable USB disk.

 Hi
 
 I use zsh and have quite perfect completion setup with it. There is just one 
 very annoying feature that I have failed to switch off. With paths when I 
 type this:
 
 cd /archives/NE tab
 
 zsh produces:
 
 cd /achieves2/NEW/
 
 The archives directory does not contain NEW directory and archives2 does. I 
 would want that zsh wouldn't modify anything but the current level path I'm 
 writing. So in this case it should of shown empty cuz there are no options 
 to choose from.
 
 This happens of course with any similar directory case. The annoyance is 
 that I know where I'm going and the right NEW directory in this case is 
 under /archives/movies/NEW and not the one under /archives2/. So I have to 
 clear some of the text which is slow :(
 
 Would anyone know how to correct this¿? I have tried various options of

 Ah, now I get it.
 
  By definition random means that the probability for every value should be
  the same. So if you have 62 options and even distribution of probability
  the probability for each of them is 1/62.
 
 Still, the increased probability for single elements should hit different 
 elements each time. So for large sets it will distribute - however, I now 
 get why it's not completely random by definition.

Usually when you need random data the quality needs to be good! Key, 
passwords etc. For example if an attacker knows that your random number 
generator same or the next index with double probability, he will most 
likely crack each character with half the tries. So for each character 
in your password the time is split in half. Again 8 character password 
becomes 2^8 times easier to break compared to truely random data. This 
is just an example though.

  Try counting how of often new_index = index and new_index = (index + 1) %
  62 and new_index = (index + 2) % 62. With your algorithm the last one
  should be significantly less then the first two in large sample.
 
 I will try that. It looks like a good approach.

Ok. I wrote a little library that takes random data and mathematically 
accurately splits it into wanted data. It is attached to the mail. You 
only need to specify the random source and the maximum number you wish 
to see in your set. So with 5 you get everything from 0 to 5 (in total 
of 6 elements). The library takes care of buffering. And most 
importantly keeps probabilities equal :)

 Done, no bits wasted. Should have perfect distribution also. We also
 don't have to throw away random data just to stay within unaligned
 boundaries. The unalignment is being taken over into the next loop so the
 error corrects itself over time (it becomes distributed over the whole
 set).
 
 Distribution will not be perfect. The same original problem persists.
 Probability for index 0 to 1 will be 2/64 and for 2 to 61 it will be 1/64.
 Now the addition changes this so that index 0 to 1 reflects to previous
 character and not the original index.
 
 The distribution of like 10GB of data should be quite even but not on a
 small scale. The next char will depend on previous char. It is 100% more
 likely that the next char is the same or one index above the previous char
 then any of the other ones in the series. So it is likely that you will
 have long sets of same character.
 
 I cannot follow your reasoning here - but I'd like to learn. Actually, I ran 
 this multiple times and never saw long sets of the same character, even no 
 short sets of the same character. The 0 or 1 is always rolled over into the 
 next random addition. I would only get sets of the same character if rand() 
 returned zero multiple times after each other - which wouldn't be really 
 random. ;-)

In your example that isn't true. You will get the same character if 6bit random 
number is 0 or if it is 62! This is what makes the flaw!

You will also get the next character if random number is 1 or 63.

That is why the possibility for 0 and 1 (after modulo 62) is twice as large 
compared to all other values (2-61).

By definition random means that the probability for every value should be the 
same. So if you have 62 options and even distribution of probability the 
probability for each of them is 1/62. 

 Keep in mind: The last index will be reused whenever you'd enter the 
 function - it won't reset to zero. But still that primitive implementation 
 had a flaw: It will tend to select characters beyond the current offset, if 
 it is = 1/2 into the complete set, otherwise it will prefer selecting 
 characters before the offset.

If you modify the sequence so that if looks random it is pseudo random. 

 In my tests I counted how ofter new_index  index and new_index  index, and 
 it had a clear bias for the first. So I added swapping of the selected index 
 with offset=0 in the set. Now the characters will be swapped and start to 
 distribute that flaw. The distribution, however, didn't change.

Try counting how of often new_index = index and new_index = (index + 1) % 62 
and new_index = (index + 2) % 62. With your algorithm the last one should be 
significantly less then the first two in large sample.

 Of course I'm no mathematician, I don't know how I'd calculate the 
 probabilities for my implementation because it is sort of a recursive 
 function (for get_rand()) when looking at it over time:
 
 int get_rand() {
  static int index = 0;
  return (index = (index + get_6bit_rand()) % 62);
 }
 
 char get_char() {
  int index = get_rand();
  char tmp = chars[index];
  chars[index] = chars[0];
  return (chars[0] = tmp);
 }
 
 However, get_char() should return evenly distributes results.
 
 What this shows, is, that while distribution is even among the result set, 
 the implementation may still be flawed because results could be predictable 
 for a subset of results. Or in other words: Simply looking at the 
 distribution of results is not an indicator for randomness. I could change 
 get_rand() in the following way:
 
 int get_rand() {
  static int index = 0;
  return (index = (index + 1) % 62);
 }
 
 Results would be distributed even, but clearly it is not random.

Sorry this example is really flawed :( If next6bit is over 61 there are only 
two possible values for it: 62 or 63 - that is 0x3E and 0x3F. So you see that 
only one bit changes. But that bit is random! So least significant bit is 
random and does not need to be discarded :)

index = get_6bit_random();
while (index  61) {
index = 5;
index |= get_5bit_random();
index = 0x3F;
}
return index;

[gentoo-user] Zsh completion

[Matti Nykyri]

Hi

I use zsh and have quite perfect completion setup with it. There is just one 
very annoying feature that I have failed to switch off. With paths when I type 
this:

cd /archives/NE tab

zsh produces:

cd /achieves2/NEW/

The archives directory does not contain NEW directory and archives2 does. I 
would want that zsh wouldn't modify anything but the current level path I'm 
writing. So in this case it should of shown empty cuz there are no options to 
choose from. 

This happens of course with any similar directory case. The annoyance is that I 
know where I'm going and the right NEW directory in this case is under 
/archives/movies/NEW and not the one under /archives2/. So I have to clear some 
of the text which is slow :(

Would anyone know how to correct this¿? I have tried various options of 
approximation... Actually I don't like the approximation at all and have tried 
to fully disable it...

[gentoo-user] Ifplugd breaks services

[Matti Nykyri]

Hi

I also have other problems in my life. One of them is on one of my gentoo 
server. This server has two network cards one serves intranet and the other 
internet. The on that is on the internet is attached to a cable modem. The 
modem is buggy and some times reboots it self losing the link so I have ifplugd 
there get new address via dhcp immediately. Intranet card is configured not to 
use ifplugd. I'm using OpenRC.

The problems are related to iptables and samba.

Samba: when ifplugd runs down the internet card samba is killed. This shouldn't 
happen. Samba is configured only to use intranet card. Samba always fails to 
start when ifplugd starts the internet card. Manual starting is required.

Iptables: the system uses new nic names (enp7s0 etc). Iptables has them 
correctly in the rules and in rules save. However when ifplugd cycles the 
internet nic all the nic names in the in-kernel rules change to eth0 an eth1. I 
need to zap iptables and then start it to reset the rules. 

Any suggestions where to start? Or just disable ifplugd?

No I don't. And as stated when dhclient sets

   Hi,
  
   I am experimenting with the C code of the ISAAC pseudo random number 
   generator
   (http://burtleburtle.net/bob/rand/isaacafa.html).
  
   Currently the implementation creates (on my embedded linux) 32 bit
   hexadecimal output.
  
  So it's a 32 bit integer.
  
   From this I want to create random numbers in the range of [a-Za-z0-9]
   *without violating randomness* and (if possible) without throwing
   away bits of the output.
  
  You mean *characters* int the range [A-Za-z0-9]?
 
 Well this isn't as simple problem as it sounds. A random 32 bit integer 
 has 32 bits of randomness. If you take a divison reminder of 62 from this 
 integer you will get only 5,95419631039 bits of randomness 
 (log(62)/log(2)). So you are wasting 81,4% of your random data. Which is 
 quite much and usually random data is quite expensive. You can save your 
 precious random data by taking only 6 bit from your 32 bit integer and 
 dividing it by 62. Then you will be wasting only 0,8% of random data. 
 Another problem is alignment, but that is about mathematical correctness.
 
   How can I do this mathemtically (in concern of the quality of output)
   correct?
  
  The easiest thing to do would be:
 
 The easiest is not mathematically correct though. Random data will stay 
 random only if you select and modify it so that randomness is preserved. 
 If you take devison reminder of 62 from 32 bit integer there are 69 273 
 667 possibilities of the reminder to be 3 or less. For the reminder to 4 
 or more the number of possibilities is 69 273 666. In mathematically 
 ideal case the probability for every index of the list should be same: 
 1/62 = 1,61290322581%. But the modulo 62 modifies this probability: for 
 index 0-3 the probability is 69 273 667/2^32 = 1,61290324759%. And for 
 indexes 4-61 the probability will be 69 273 666/2^32 = 1,6129032243%.
 
 If you wish not to waste those random bits the probabilities will get 
 worse. With 6 bits of random the probability for index 0-1 will be 2/64 
 and for 2-63 it will be 1/64. This is a very significant change because 
 first and second index will appear twice as much as the rest. If you add 
 2 characters to your list you will perfect alignment and you can take 6 
 bits of data without it modifying probabilities.
 
 If you are looking a mathematically perfect solution there is a simple 
 one even if your list is not in the power of 2! Take 6 bits at a time of 
 the random data. If the result is 62 or 63 you will discard the data and 
 get the next 6 bits. This selectively modifies the random data but keeps 
 the probabilities in correct balance. Now the probability for index of 
 0-61 is 1/62 because the probability to get 62-63 out of 64 if 0.

  static char S[] = { 'A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J',
  'K', 'L', 'M',
  'N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W',
  'X', 'Y', 'Z',
  'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j',

  'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w',
  'x', 'y', 'z',
  '0', '1', '2', '3', '4', '5', '6', '7', '8', '9' };
  
  int
  next_character()
  {
  // Use the correct call for ISAAC instead of rand()
  unsigned int idx = rand() % N;
  return S[idx];
  }
 
 so modify the next_char function:
 
 char next_character()
 {
   static unsigned int rand = 0; //(sizeof(int) = 32)
   static char bit_avail = 0;
   char result = 0;
   char move_bits = 0;
   char bits_moved = 0;
 
   do {
   if (!bits_avail) {
   // Use the correct call for ISAAC instead of rand()
   rand = rand();
   
   bit_avail = 32;
   }
 
   move_bits = bits_avail = 6 ? 6 : bits_avail;
   result = move_bits;
   result = (result | rand  (0xFF  (8 - move_bits)))  0x3F;
   bits_avail -= move_bits;
   bits_moved += move_bits;
   rand = move_bits;
 
   } while (bits_moved != 6  result  61);
 
   return result;
 }

Well actually it looks simpler if you break this like this:

unsigned char get_6bits () 
{
static unsigned int rand = 0; //(sizeof(int) = 32)
static char bits_avail = 0;
unsigned char result = 0;

//get 2 bits 3 times: 32 is devidable by 2
for (int i = 0; i  3; i++) { // --std=c99
//Fill buffer if it is empty!
if (!bits_avail || bits_avail  0 ) { //if bits_avail  0 it is 
an error
