How would you physically connect the automotive battery to the computer, and 
would you need the shell of the old UPS?

I have an old Tripp-Lite UPS, batteries are dead and no longer rechargeable.

Would you connect only the computer, or would you connect the monitor as well?  
Would you connect networking equipment?

[gentoo-user] Can Portage be used with FreeBSD or NetBSD?

[Thomas Mueller]

Can Portage be used as a package manager with anything other than Linux? 

I like some features of Portage; think it might be better than FreeBSD ports or 
NetBSD pkgsrc, or is just a case of the grass being greener on the other side?

I like the option "--with-bdeps=y", wish FreeBSD's synth and poudriere had that 
option.

But I don't want to use Portage where it would be incompatible.

Portage's assumption of location of python binary and /bin/bash are contrary to 
anything non-Linux, or even a Linux that uses another shell such as dash or 
mksh.

[gentoo-user] Building kernel without messing the kernel source tree

[Thomas Mueller]

I am looking to compile the Linux kernel and send the work and output to 
another directory, thereby leaving the kernel source tree directory clean.

If I build gcc or other software using configure script, I can go to another 
directory and run, for instance, ~/builds/gcc-8.3.0/configure --prefix=/usr ... 
without dirtying the source directory.

This would likely be a cross-compile from NetBSD or FreeBSD. 

Could I do make -C ~/builds/linux-4.19.105 ARCH=x86_64 
CROSS_COMPILE=x86_64-linux-musl- ... ?

That would be my first thought, seeking to avoid having to clean after every 
run, successful or unsuccessful.  Avoid the worry about whether clean, 
distclean or mrproper work.

I would like to compile for x86_64 and also i486 (or would that be i386)?

Is this a question for gentoo-user or gentoo-dev?

The "make" I use is built from GNU source, not /usr/bin/make as is found on 
NetBSD or FreeBSD.

2000 posts per day on Linux kernel list would be more than unmanageable for me! 
 I wouldn't say "almost"!

Is Linus Torvalds' removal of console scrolling the reason why Scroll Lock does 
not work on the console with System Rescue CD or USB, while with FreeBSD and 
NetBSD, I can press Scroll Lock and scroll back?

I like that ability but don't think Linus Torvalds is listening or reading this.

Further, with System Rescue console, the lines/text go only partway down.

Using screen, now at v4.8, means having to remember a lot of key functions, you 
need a separate reference screen to look them up.

There is also tmux, which is part of the base system in NetBSD but not FreeBSD.

If Linus cared about his users, he could make the kernel headers more 
user-friendly, installing kernel headers should not be any more complicated 
than copying or downloading.

Console scrolling is especially useful with an OS or distro that is built from 
the ground up, like Gentoo, Void or Arch, as opposed to being installed all at 
once.

If more Linux users would go to and try NetBSD or FreeBSD, those OSes would 
have more users, more ideas, more ability to improve.

I remember from when nobody ever heard of GPT, fdisk was used to partition a 
hard drive, long before the days of GPT or USB.

Then Rod Smith developed a gdisk to partition a drive using GPT; could even be 
used on a USB hard drive or USB stick.

Linux fdisk was much easier to use than FreeBSD or NetBSD versions of fdisk.

I don't know how newer versions of Linux fdisk would do with traditional BSD 
disklabels, which are not compatible between the various BSDs.

But now FreeBSD and NetBSD can run on GPT with no traditional BSD disklabel.

I am not familiar with Sun or SGI partition tables.

Is it necessary for the ESP to be FAT32, as opposed to FAT16 or FAT12?

What happens if the ESP is formatted FAT12 or FAT16?

In some cases, ESP might be small enough that FAT32 would not be appropriate, 
especially when there is only one OS installation on the disk.

That would be the case on many MS-Windows or Mac computers, and also other OSes 
when installed on a USB stick.

I never used parted or gparted, but prefer to put "home" in a different 
partition.

That way, if you mess up or otherwise have to reformat the root partition, home 
is unaffected.

Also, you can access the same home partition from more than one OS installation 
that can read/write the file system, in this case ext2 or ext4.

I didn't know getmail was deprecated, but haven't used getmail in a long time.

Maybe deprecated because of using Python 2.x which is deprecated?  Or did 
they/could they port to Python 3.x?

I use mpop and msmtp but am considering other possibilities including mutt.

I want to keep email in a format that does not limit use to one particular 
application.

I tried to use fetchmail long ago, the problem was that it would not allow

I suppose you could use mutt; I also have Steffen Nurpmeso's s-mailx on the

What put me off Slackware was their package manager completely ignoring

That raises the question, what if you have no kernel config, as may be the case 
if you are going to Gentoo for the first time, or are cross-compiling from 
FreeBSD or NetBSD?

I have tried with OpenADK (www.openadk.org), which got as far as successfully 
building cross-gcc some of the time, but never succeeded at building the kernel.

Is defconfig the best starting point?  One would want to maximize the 
probability of success building the kernel while retaining a functional system 
that would support vital hardware including ethernet, wi-fi, hard drives and 
USB, and I would need to be able to read a NetBSD or FreeBSD file system 
(UFS/FFSv1 or 2).  I use GPT, so there are no traditional now-deprecated BSD 
disklabels that Linux would not recognize.

If I just start with menuconfig, I could miss some vital parts.

OpenADK started with a minimal kernel config, maybe it was too minimal?

I have successfully compiled kernels and userlands on FreeBSD and NetBSD (no 
menuconfig, defconfig, etc; kernel configs start with a GENERIC config).  
NetBSD kernel config is much longer than FreeBSD kernel config but is dwarfed 
by Linux kernel config.

I've created a bug report out of this. Stage3-files shall be upgraded at

stage3-files and therefore portage-tools shall match what files within the
portage-tree give.
If the is not the case, it will be nearly impossible to set up an

Re: [gentoo-user] Re: trying to upgrade some old, never upgraded image for an embedded system …

[Thomas Schweikle]

So I've tried now to upgrade in various ways:
1. the one given in https://anongit.gentoo.org/git/repo/sync/gentoo.git
  But this fails as soon as I try to emerge git. python-exec is at version
2.4.6 now. Without any 2.0.1 packed, legal versions left. Same for all
other dependencies. Not really a way to go …

2. I've tried downloading a recent stage3 file, unpack it, then go and
upgrade from there. The recent stage3 file, I had to find out is, dating
from 29th, September 2016, way outdated.It isn't even useful to compile
anything. It will fail with any of the packages from portage as well.
Upgrading portage-tree from there works, but – EAPI version mismatches make
it impossible to compile anything.

Since there isn't a stage3 and some portage tree matching, I'd ask: armv7
and others have gone unsupported? Just because nobody ever created a new
stage3 file matching EAPI changes?

[gentoo-user] trying to upgrade some old, never upgraded image for an embedded system

[Thomas Schweikle]

trying to upgrade some old, never upgraded image for an embedded system I
ran into a problem I do not have a solution for:

!!! All ebuilds that could satisfy
">=dev-lang/python-exec-2:=[python_targets_pypy(-)?,python_targets_python2_7(-)?,python_targets_python3_5(-)?,python_targets_python3_6(-)?,python_targets_python3_7(-)?,python_targets_python3_8(-)?,-python_single_target_pypy(-),-python_single_target_python2_7(-),-python_single_target_python3_5(-),-python_single_target_python3_6(-),-python_single_target_python3_7(-),-python_single_target_python3_8(-)]"

request:
- dev-lang/python-exec-::gentoo (masked by: EAPI 7)
- dev-lang/python-exec-2.4.6-r1::gentoo (masked by: EAPI 7)

The current version of portage supports EAPI '6'. You must upgrade to a
newer version of portage before EAPI masked packages can be installed.

I am curious about your USB and eSATA enclosure.

I have two such Sabrent enclosures, USB 2.0 and eSATA.

USB 2.0 works with IDE or SATA hard drive, while eSATA works only with SATA 
hard drive.

I also have a Micronet Fantom G-Force hard drive with USB 3.0 and eSATA 
connections.

I use mpop and msmtp.

I tried to set up fetchmail many years ago.  One deficiency is that it didn't 
allow downloading email to a file (mbox).

I used getmail, which is a Python script, many years ago after giving up on 
fetchmail.

I believe hplip, used for some HP printers including multifunction, depends on 
Python 2.7, something that needs to be corrected/updated. Or is that already

I used Konqueror long ago, in the days of KDE 3.5.8, on Slackware, it was a 
great info viewer, much better than Emacs or info itself; also a good web 
browser.  At that time, I had never heard of Gentoo.  Now all I have to read 
info is pinfo.

When KDE went to 4.x, I had a much more difficult time finding my way, even 
icewm was much better.

Now it's been I-forget-how-many years since I last used KDE.

I am still not a fan of info, one of the downsides of GNU/Linux.

[gentoo-user] setup.py question: platform.system()

[Thomas Mueller]

I was just looking through gentoo/setup.py and find something that arouses my 
curiosity.

I see

if platform.system() == 'Linux':
x_c_helpers.update({
'portage.util.file_copy.reflink_linux': [
'src/portage_util_file_copy_reflink_linux.c',
],
})

Question that comes up is, what if platform system is something other than 
Linux, such as FreeBSD, NetBSD or other.

How would setup.py handle that?  Would it attempt to set up portage-style 
package manager for FreeBSD, NetBSD or other, would it set up something for 
Linux portage, or would it just fail?

Being on the same local network, the other machine would have an intranet IP

Whenever you compile your kernel, you will need to run

Re: [gentoo-user] Removal of media-plugins/npapi-vlc

[Thomas Schmitz]

Hi Petric,

as far as I know the VLC browser plugin allows you to play back media using
VLC. However in my opinion you don't need that. Firefox has its own
playback backend and hence it can play back media without the VLC plugin.

So I think you shouldn't run into any issues if you don't use npapi-vlc. To
my understanding Firefox bundles its own codecs unless specified otherwise
through USE flags.

Thomas Schmitz

Re: [gentoo-user] Re: Firefox 57.0.4 without pulseaudio? Possible?

[Thomas Bracht Laumann Jespersen]

I was doing the exact same thing this weekend! The answer is yes (I think).

I'm not on my Gentoo box at the moment, so I'm not 100% sure that I
don't have apulse - I don't recall installing it, but I definitely
don't have pulseaudio. The sound was working (with speakertest), but I
had no sound in Firefox. I found a forum post [1] that said to find
these two settings in about:config:

browser.tabs.remote.autostart
browser.tabs.remote.autostart.2

and set them both to false. For me, the latter was already false, but
the first was set to true.

And then the sound worked! Hope it works for you,

/usr/local is the default LOCALBASE in FreeBSD, but I believe you can set 
LOCALBASE to something else in your environment, which could be set in 
/etc/make.conf .

You could possibly copy Gentoo scripts to /usr/local/gentoo-scripts, or would 
that not work with your scripts as set up?

You would have to be careful setting up your PATH in .profile and /etc/profile 
, to make sure it includes the proper LOCALBASE.

Re: [gentoo-user] Is this working correctly??

You (Dale) seem to have corrected the multipart/alternative problem, except one 
message (Subject: Re: [gentoo-user] Re: downgrading glibc) where 
multipart/alternative went through.

I would never design an email client to send multipart/alternative by default, 
and might design an email client to not support multipart/alternative at all in 
composed messages.

A 5.5M log is too much for most people, myself included, to read.

Gzipping has two disadvantages: can not be read directly, one being that the 
attachment must be extracted to a separate file for reading outside the mail 
client.

Other downside is that a gzipped file must then be base64-encoded for email.  
Base64 encoding multiplies the attachment size by 4/3 (four-thirds), negating 
most of the reason for gzipping.

Another possible reason for this is that X is running as your user and
not root. I am not very familiar with how X and displays work, but I've
stumbled upon similar errors before when trying to run certain GUI
programs through root or sudo. I've usually solved this by giving my
regular user some permissions (usually just groups) and ran it as my user.

Though if this happens as part of emerge I've no idea how to go about
fixing it. It might be that what I've seen earlier is just my own FUBAR
sys and config.

linode.com and kimsufi.com lets you install gentoo. There might be many

You might want to look into something like cfengine, puppet or chef to
lessen your workload of running multiple machines.

I've used linode for a couple years and its never been any problem, I do
see that I'm probably paying for more than I need, but that's another story.

Well I'm not sure if you can achieve this sort of censorship with a
proxy server, but might be possible.
Nevertheless white-listing will be hard work. I don't know if privoxy[1]
is able to white-list, but I would give it a try and find out. This post
[2] looks promising if you can blacklist everything in the first run
(but don't know how) and then white list just the domains you want.

Many sites now, including YouTube, and many spammers, have gone over to HTML5, 
though some of those also work with Flash.

Under FreeBSD, I built gnash from ports, that worked with YouTube but not much 
else but can't be built for FreeBSD >=10.

I tried swfdec, but that didn't work on anything.

There is also lightspark; I am not familiar with its status. 

In some cases, it is possible to download a Flash video with youtube-dl or 
get-flash-videos.

Adobe Flash remains a bitter reality on mlb.com, nfl.com, wfpl.org, AT 
Uverse, among others.

USB hard drives, in my experience, come with and require AC power adapter, are 
not powered by the USB itself.

USB sticks don't need or have their own power.

I bought a WD Green 3 TB hard drive in May 2011, warranty was then 3 years.  It 
went bad with errors after 34 months.

I was able to get a warranty replacement after much hassle, with the warranty 
on such drives down to 2 years.

That replacement hard drive went bad in about seven months, strange sounds 
reminiscent of a dialup modem, drive was no longer recognized by the computer.

At nearly the same time as the WD Green failure, a 3 TB My Book Essential 3 TB 
USB 3.0 hard drive, ordered at the same time as the WD Green drive, went 
somewhat bad with errors, but the warranty on that was 2 years.

Needing a hard drive for another computer (May 2013), and not trusting WD or 
"Green", I ordered a Seagate NAS 4 TB hard drive, figuring increased 
reliability compared to Barracuda or Desktop was worth the modest additional 
cost.

That drive is still good as far as I can tell.

Now I am considering an external hard drive with eSATA, more suitable for OS 
installation (Linux, NetBSD, FreeBSD, Haiku?) than USB 3.0.  Only brand I find 
is Micronet Fantom (GForce), or use Seagate NAS hard drive in an enclosure with 
eSATA.

I really can't see why USB 3.0 is so more widely available than eSATA when 
eSATA seems superior as far as I can tell.

Just checked, and mtab is not a symlink. It is a plain text file.

Just tried takinga backup of mtab and symlinking /proc/mounts onto
/etc/mtab yields no different results when trying `/etc/init.d/dbus

[gentoo-user] Unknown problem causing incorrect mounting and daemons not starting

[Thomas Sigurdsen]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA256

There is an html version of this mail, that also has emerge --info and
my kernel config, at:
http://browniehive.net/tmp/hp-problems.html

I've come to a dead end in troubleshooting this issue and turn to you
for help in how to continue. The following is what I've discovered
during troubleshooting.

# FS's not Mounted After Boot

After login I need to remount `/` with rw. I always then mount `/boot`,
`/mnt/hdd`, `/home/thomas/hdd` manually; that is --- with the `fixmnt`
script I made pasted below.

before doing the above `mount` command tells me that the FS's are
mounted as they should be, but they contain no files.

## `~/bin/fixmnt`


#!/bin/bash

sudo ip link set lo up
sudo dhclient enp0s25

cp /etc/mtab /home/thomas/mtab-$(date -Iminutes)
wgp=$(wgetpaste /etc/mtab)

sudo mount -o remount,rw /
echo $wgp >> /home/thomas/wgp-$(date -Iminutes)
sudo mount /boot
sudo mount /mnt/hdd
sudo mount /home/thomas/hdd
sudo swapon /dev/sdb2
#ip link set lo up
#sudo ip link set lo up


As I can't put a copy of `/etc/mtab` anywhere on a read only FS you
won't see what it looks like before running the `fixmnt ` script. The
script gives off an error for the call to cp that I've just ignored for
now (also the wgetpaste doesn't work as it requires creating files in
`/tmp/`, which at that point in time is not writable).

# Daemons Won't Start

You can see from the above that `net.lo` does not get started and there
are some daemons that haven't started and won't start when called. Some
I can start through calling their commands directly (I do this with
`privoxy` and `tor` at the moment in a `tmux` session for browsing).
Other daemons won't start no matter what I try, like `dbus`.

## `/etc/init.d/dbus start`

Because of the above output I wonder if this is because of some FS or
disk error (crossing fingers for software/config and not hardware) the
culprit could be `fsck.xfs`.

I have run fsck (including `xfs_repair` on the xfs partitions) on all
partitions, with no problems reported from a trisquell livedisk. I also
tried running fsck on `/dev/sda1` from the installed Gentoo instance;
got no errors and didn't change any behaviour as far as I have noticed.

# Overview of System

Sometime in the beginning of October I installed an ssd in this laptop
and migrated to it. The problems started after this, but I am unsure
precisely when as I didn't reboot much in between the migration; for all
I remember now these problems might have started a while after the
migration. `sdb` is the "new" ssd while `sda` is the old hdd.

As you can see from `fstab` I tried putting `/dev/sdb3` as the boot
partition when I installed the ssd.

## `/etc/fstab`


#/dev/sdb3  /boot   ext2noatime 1 2
/dev/sda1   /boot   ext2noatime 1 2
/dev/sdb1   /   ext4noatime,discard 0 1
/dev/sdb2   noneswapsw  0 0

 I wouldn't advise that on the portage tree because if you edit any files under

It will still pull but you'll potentially have conflicts to resolve.

A bad idea in any case.

Now many repositories use git, and I need to know how to make changes to some 
files, hopefully a small number, but still be able to update with git.

I keep the modifications somewhere for safekeeping, as well as the originals, 
but would want to see the updated files straight before remaking my 
modifications.

I looked through man pages, git pull --rebase didn't work; I got error 
messages.  Should I do git reset or should I git checkout each modified 
file one-by-one before git pull?

There is a lot in git, learning git all the way through looks like a tall order.

Re: [gentoo-user] gru2-mkconfig tries to read the extended partition ??

[Thomas Mueller]

 N one is forcing you (unless you have a UEFI board), and more than anyone
 is telling you not to use a 2.4 series kernel.

 Neil Bothwick

This brings a question to mind: Does anybody know what Linux kernel was the 
first to support GPT?

Slackware 13.0, released in 2009 with kernel 2.6.29.6, did not support GPT, 
could not read the SATA hard drive on the rare occasions when it booted from 
its new home, IDE hard drive inside USB 2.0 enclosure.

NetBSD (3.0) and FreeBSD (7.0) got GPT support long before 2009.

Regarding problems dealing with Dell as discussed in this thread, I prefer to 
buy parts and build my computer.  That way I get more choice, more up-to-date 
hardware, and more intimate knowledge of what's inside.

One possibility for installing MS-Windows in this case is getting a low-price 
refurbished small SATA hard drive, and installing Linux, and FreeBSD, NetBSD, 
Haiku, if desired, on a bigger hard drive.

Today's UEFI permits selecting boot device, and no more slave and master issues 
such as plagued IDE hard drives.

Still, there might be the risk that the Windows installer might see the other 
hard drives and do some nasty things.

Tom

Re: [gentoo-user] Securely deletion of an HDD

[Thomas Mueller]

All that has been said on this thread supposes that the hard drive is still 
readable and writable.

But the original post stated this was a failed drive.

Then you might not be able to dd if=/dev/zero of=/dev/sdx .. or whatever else.

You would be stopped by bad sectors.

Or a hard drive might not be accessible at all through the computer interface.

I heard something that sounded like a modem dialing, but had no such modem.  

Going around with my eyes and ears led me to determine that it was a hard drive 
whining in an external eSATA enclosure, no longer recognized or accessible from 
the computer.

That was a Western Digital Green 3 TB hard drive that replaced, under warranty, 
a WD Green 3 TB hard drive that developed bad sectors.

Fortunately I had no confidential data on that hard drive.

So everything in this thread says nothing about if the hard drive failed due to 
a mechanical problem.

Then the data could not be overwritten by ordinary means, but could still be 
read by techniques such as used by Drive Savers.

Re: [gentoo-user] necessary use flags

[Thomas Mueller]

 Best way I ever found to learn how things really work under the hood is
 to build a Linux From Scratch and pay close attention to every single step.

 Not that you'd ever actually *use* that system - there's no sane package
 management for a start - but after building an LFS, the content of
 ebuilds in @system starts to make a lot more sense; you can see why some
 of the decisions in the profiles were made; and make.conf now appears in
 a whole new light.

 Then take the valuable lessons from LFS and apply them appropriately to
 using Gentoo. These things are tools and the best workmen are always
 very familiar with their tools as a co-ordinated whole (as opposed to a
 bunch of mish-mash stuff cluttering up a toolbox)

 Alan McKinnon

One could build a system with LFS or CLFS and then adopt one or more package 
managemant systems such as Gentoo portage, pacman with Arch Build System, 
voidlinux, etc.

Different package management systems would go to separate installations, 
separate partitions, of course.

Lack of package management, or actually package management that had no 
recognition of dependencies, was a large part of what made me not continue with 
Slackware beyond now-outdated 13.0.

I was spoiled by FreeBSD ports, NetBSD pkgsrc, and Linux distros with package 
management that recognized dependencies.

Re: [gentoo-user] portage alternatives

[Thomas Mueller]

 from Michael Vetter:

 just for fun I am reading about alternatives to portage. So far the most
 interesting I found are: paludis and pkgsrc.

 paludis mostly because it seems to come from some gentoo-like enviroment
 and pkgsrc because of the nice thought to have the same pkg files for
 multiple OSes.

 Is anybody of you using one of them and can tell me about pros and cons?

I've read a bit about paludis, the package manager in Exherbo, forked from 
Gentoo, but haven't got to try it yet.

I am familiar with pkgsrc, use only in NetBSD where it is native.

For FreeBSD, I use the FreeBSD ports, notice that pkgsrc seems to have nothing 
to compare to portmaster and portupgrade.

In pkgsrc, you can update all packages with pkg_rolling-replace, but not so 
easy to update just one package/port and its dependencies.

pkgsrc seems directed at BSD, where there is a distinction between packages and 
base system.

In Linux, I get the impression that everything is a package, including what 
would be part of a BSD base system and not well-covered in pkgsrc.

I've fallen behind on following this list, too many emails elsewhere, which is

[gentoo-user] hostapd wlan ap AR9485 and Intel Centrino Advanced-N 6205 Windows 8

Hi All,

Just in case anybody ever stumbles into the same issues.

I had huge performance issues with my work notebook Lenovo T430s running
Windows 8 and an Intel Centrino Advanced-N 6205 wireless network adapter,
connected to my Gentoo machine that has a TP Link TL-WN781ND network
adapter.

With performance issues I mean: the task manager showed only 802.11g
instead of n - and even this was not working fine as I had connection
drops, low reaction when connected via SSH to the machine, etc.
When using, for example, www.speedtest.net the test could not start due to
a failing ping and iperf showed about 100Kbit/s...

My setup is:

it's free to download...) and I could not find a way to display the
connection type... speedtest.net showed 25MBit which is the maximum my
provider would provide for what I pay :)

I was trying to resolve the issue by trying out various ht_capab settings,
wmm_enabled, wmi_enabled etc... nothing helped.

What did help in the end is... updating the Windows driver through the
device manager! Windows now displays 802.11n and iperf gives me 37.3
Mbits/sec, which is probably acceptable given the fact that I live in a
quite densely populated area and the PCI adapter in the server has only
2.4Ghz support.

So, if anyone experiences similar issues with Intel Centrino Advanced-N
6205 on Windows 8, try to update the driver first.

[gentoo-user] Re: Allow delay for booting from USB device?

[Thomas Mueller]

Thanks to Joost Roeleveld and Brian Hesdorfer for helpful answers.

Even before getting the new email, I googled on linux boot root delay and found 
the answer where previous Google search failed to yield results.

That was an old Linux, Slackware 13.0 with kernel 2.6.29.6 where I remember 
trying to get started with Gentoo but the kernel I built, compile time 130 
minutes, failed to boot.  It still took many attempts before I was successful 
with the boot.  No Internet access because the kernel is too old and the 
Ethernet too new.

[gentoo-user] Allow delay for booting from USB device?

[Thomas Mueller]

Is there a way to make Gentoo or other Linux allow extra time when root is on a 
USB device?  Any way to say just a second or more like 15 seconds before 
aborting with the message that root partition does not exist?

In this case it's an IDE hard drive in a USB enclosure.

FreeBSD seems to handle this situation better.  I would get a 
mountroot
prompt, to which I would respond 
ufs:/dev/ada0p3
and be good.

I could avoid this situation with /boot/loader.conf

legal.realtek.license_ack=1
rsu-rtl8712fw_load=YES
kern.cam.scsi_delay=13000 # Delay (in ms) before probing SCSI
kern.cam.boot_delay=16000# Delay (in ms) of root mount for CAM bus
hint.re.0.disabled=1

but don't know if Linux has anything like this.

Only lines 3 and 4 are relevant to this issue; other lines are for different 
issues.

[gentoo-user] Root password, keys, and authentication

[Thomas Sigurdsen]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

Hi list.

I have for some time now been trying to avoid using passwords as much as
possible, preferring encryption keys instead (e.g. public private key
encryption like gpg and such). I have also started using longer
randomised passwords I shouldn't remember; storing them instead in a
safe place (e.g. encrypted memory card or flashdisk).

So when setting up a new Gentoo machine today and being about to enter a
new root password I found myself wanting a way of doing authentication
through some other means than remembering a password, like gpg or
certificates. Does this exist; and if anyone has had experience with it,
is it worth the hassle? And if this is a bad way of doing root
authentication, why/how?

Also the machine in question will have more than one user and a subset
of the users shall have access to the root account.

 that these are first year students in a common first year, they have

 don't see any benefit in doing programming but have to pass the
 subject.

 My requirement is that it boots into a GUI, preferably straight
 into the environment, no username/password, has dhcp, a decent editor,
 a browser and gcc or clang.

System Rescue CD fulfils the above requirements.  You can go straight to XFCE, 
be root with no user/password, by default automatically configures network with 
DHCP.  Editor is vim (I believe), browser is Midori, and gcc is present; I 
didn't think of looking for clang.

Re: [gentoo-user] k3b burning BD-Disk pretends to fail at 99.99%

[Thomas Schmitt]

Hi,

 attemting to create a 
 BD-RE disk (Re-recordables are nice, sine non-RW media don't grow in my
 garden ;-)

Yeah. A BD-R tree would be a fine thing.

Note that growisofs on BD-RE would not show the bug at the end.
It happens only with BD-R which you submit in blank state.

If you treat your BD-R with dvd+rw-format before using them,
the bug should not show up.

If you can talk K3b into using growisofs option
  -use-the-force-luke=spare:none
then it will not format the blank BD-R, work with full nominal
speed, and should not show the bug. (There will be no Defect
Management. So there will be no checkreading and no replacement
of bad blocks.)

Re: [gentoo-user] k3b burning BD-Disk pretends to fail at 99.99%

[Thomas Schmitt]

Hi,

 maybe the problem is when closing the session or writing some kind of lead-
 out, or the like.

The problem is that the CLOSE TRACK/SESSION command is appropriate
for the end of burning BD-R, only if it is unformatted or if it is
formatted to SRM without Pseudo Overwrite.

As soon as it is formatted to Pseudo Overwrite, the command is
inappropriate, which the burner indicates by the ILLEGAL REQUEST
error code (which one would see if K3b would not swallow it).

The bug of growisofs is that it formats the BD-R to Pseudo Overwrite
but omits to memorize this new state.
If the BD-R is already formatted to Pseudo Overwrite when growisofs
inspects it, then its state gets memorized and the inappropriate
SCSI command is not issued.

My patch proposal just sets the memorizing Pseudo Overwrite flag
after the medium has been formatted. So growisofs treats it the
same as if it had already been formatted when growisofs first
inspected it.
This avoids the error.


Have a nice day :)

Re: [gentoo-user] k3b burning BD-Disk pretends to fail at 99.99%

[Thomas Schmitt]

Hi,

michaelkintz...@gmail.com:
 Hi Thomas, this problem can either be fixed by patching growisofs as you 
 suggest, or by changing k3b to use cdrtools in preference to growisofs

Joerg will heavily object, but my sincere opinion as
technical expert on this field is that growisofs is
the better choice.

I mentioned in this thread what i dislike about it.
Joerg added the fact that it is unmaintained since 5 years.

But aside from that, i cannot point to any reason why
growisofs is an inferior burn backend compared with my
own software which i try hard to make as good as possible.


 Joerg keeps his code up to date

Yep. Joerg and i seem to be the only active developers on
this field.

But there has nothing new happened with optical media since
Andy left the playground. If not for this BD-R bug, nobody
would care that growisofs is unmaintained.
Currently i have the impression that in most distros the
whole topic of optical media and their filesystems is
unmaintained or at least under-maintained.


cdrecord on DVD and BD suffers from Joerg's peculiar way to
read the specs (and to not disclose which paragraphs exactly,
when his understanding is brought into question).
His and my understanding of MMC seem fundamentally incompatible.

Obviously Andy Polykov read the same specs as i, when he
created dvd+rw-tools.

If people need technical support about growisofs, then i am
ready to help. I am subscribed to cdwr...@other.debian.org
which is the official place to submit bug reports and requests
for dvd+rw-tools.

If it is possible to let K3b use cdrecord for DVD and BD,
then i would apply for enabling my program cdrskin, too.
(Actually i think it would be easier to emulate growisofs
 capabilities by cdrskin than by cdrecord.)

Re: [gentoo-user] k3b burning BD-Disk pretends to fail at 99.99%

 However, your patch is for growisofs, which in Gentoo comes from
 app-cdr/dvd+rw-tools, so the proper place for such patch would be
 cdwr...@other.debian.org per http://fy.chalmers.se/~appro/linux/DVD+RW/ --

On that list there was support by Andy Polykov until shortly
after the bug in question was reported. A fixed release was
promised but did not emerge. See
  http://lists.debian.org/cdwrite/2008/07/msg00092.html


 IIRC you mentioned in another email being subscribed to that list.

Yep. Until 2007 as user of growisofs. For a short while as
friendly competitor. Now as its sentinel, so nobody has reason
to regret having tried burning DVD on Linux.


 Just curious...if you don't use Gentoo, why do you subscribe to
 gentoo-user list?

The topic came up from a side note on cdrkit's mailing list.
The Fedora maintainer of growisofs asked whether i know more
about the problem. I pointed to above post by Andy, re-read it
and recognized that he left a treasure map to find the bug.

After getting confirmation that the proposed fix works, i googled
for similar bug reports in various distros.

An archive of the gentoo-user list was among the found sites.
My first mail to the list did not show up. So i subscribed a day
later and sent it again.

Re: [gentoo-user] k3b burning BD-Disk pretends to fail at 99.99%

[Thomas Schmitt]

Hi,

 Okay, then, is your patch necessary when using this command:
 growisofs -dvd-compat -Z /dev/sr0=image.iso
 with a DVD?

No. I do not know about any growisofs flaws with DVD.

(Besides its -use-the-force-luke magic which is reserved
 for those who read growisofs.c additionally to its man page.)


 Because I don't own any BluRay discs, or players.

The bug fix has an effect only if you submit a blank BD-R.
It is necessary if one cannot live with growisofs reporting error
and returning a non-zero exit value.

There are rumors that the inappropriate command spoils the burn.
But this is not very plausible because the Pseudo Overwrite
burn is already done when the error happens.


 I do remember that in the past I've experienced a similar error where it
 appeared to me that growisofs seemed not to close media, but the data on the
 DVD was fine, so I didn't pursue it.

That must have been something else.

Closing the medium should indeed happen with -dvd-compat.
But of course one cannot close DVD+RW, formatted DVD-RW, DVD-RAM,
or BD-RE ... and obviously not Pseudo Overwrite BD-R.

dvd+rw-mediainfo would have told what's up with the medium
after the burn. (It helps to have a copy of MMC specs at hand
when reading its output.)


My offer holds: I am willing to investigate any burn problems.
Be it with my own software or the one of others.
(I must restrict my offer insofar that i will not waste lots
 of expensive one-time media for mistakes which i did not make
 myself.)

A typical first experiment will be to use my own software
with the problematic combination of burner and medium.
This shall not mean that in the end i will urge people to
switch to my stuff. The goal will be to find out what's
wrong with the user's situation and how to possibly fix it.

(Cough.)

growisofs is unsurpassed with DVD. I am a competitor of it

respect to the SCSI standards SPC-3 and MMC-5.

With BD it has one bug and two design decisions which i do not
agree with.
The bug is the one which i strongly believe is reported here.
We could know for sure if Alex would try the proposed fix.

The two decisions are formatting BD-R to Pseudo Overwrite capability,
and not offering writing without Defect Management to formatted BD.
Defect Management reduces write speed to at most half nominal
media speed. Pseudo Overwrite puts an extra layer of complexity
onto BD-R burning.

The bug is easily fixed, and the design decisions are features for
which the author has made his point in

I do not agree, but i cannot flatly reject his reasons, either.

In the source files of growisofs i can spot only one occasion
of MODE SELECT. This is in transport.hxx where Andy composes
a mode page 05 for DVD-R[W].

I read in SPC-3 6.9.3 that the drive shall throw error if one
attempts to change a non-changeable value. But not that the drive
is allowed to return values which may cause error if sent back
to the drive.

So if the code of transport.hxx is wrong, then not because it
would send back values which it got from the drive, but because
it does not inquire by PC=01b whether its self-constructed values
are allowed to be changed.
(I don't do this either. It is worth consideration, though.)

 My experience has been the opposite, that even the cheapest USB network 
 adaptors have worked.

 Maybe I've just been lucky and this is not the norm, but from what I've seen 
 USB network adapters don't work with Linux is the sort of thing that might 
 have been true 10 years ago.

Are you talking about an adapter that plugs into a USB port at one end and has 
an Ethernet port at the other end?

Or are you talking about a cable or DSL router with a USB connection?

I have a cable modem and router, the router can connect by either Ethernet or 
USB; I always used the Ethernet and never used the USB.

But I had a DSL modem/router before the switch to cable, had both USB and 
Ethernet connectors.  I failed to get the USB network connection to work, 
though the Ethernet worked OK.

Re: [gentoo-user] Any way of tracing kernel freezes?

[Thomas Mueller]

Excerpt from Frank Steinmetzger:

 I found my old USB Gentoo which has memtest installed (and which I used
 for my first test also). I let it run for two passes, both successful.
 So the RAM seems fine.

  Temperature? - check for dust puppies clogging the heatsinks, cooling etc.

 It's a netbook with a 6.5 Watt CPU. I'm going through the big emerge
 again right now (3.5 hours in), and it never goes above 66°. Besides, the
 freezes also happened when I didn't do anything heavy. Just surfing
 (though Firefox can also be heave for an Atom ^^).

 Anyhoo, I'm running 3.8.13 again now. I didn't have my config anymore,
 so I oldconfig'ed it from 3.9. Let's see whether it's more stable. If
 yes, hm... I can't really report this to the kernel devs: My netbook
 freezes since 3.9, that's all I know. Here, have my configs. :-I

Is your temperature of 66° F or C? 

System temperature or surrounding room temperature?

I have an old computer whose fan has quit as happened once before.

CPUs generate considerable heat, I see system temperature and realize the fan 
is much more critical than whether the room temperature is a chilly 20 C or 
sweaty (for humans) 35 C.

I don't use that old 2001 computer much, am getting ready to put together a new 
computer from parts to run FreeBSD and Linux, likely Gentoo; otherwise I'd 
order a Socket A fan.

When I do use that old computer, I open the case and prop a hair dryer to run 
at low, ambient-temperature air pointed at the CPU.  This keeps the CPU down to 
47 C according to the BIOS/CMOS screen.  This is cool for the CPU if not for us 
humans.

Re: [gentoo-user] Who/what names hard drives /dev/sda, /dev/sdb, etc

[Thomas Mueller]

 Who or what decides to name a hard drive /dev/sda vs /dev/sdb?

 How does it decide what order to enumerate the drives on my computer?

 When in the boot process does is a disk given a name like /dev/sda?

 Thank you,

 Chris

I believe it depends on how the drives are connected. 

/dev/sda would be the default boot drive, though modern computers can be 
configured to boot from any drive recognized by the BIOS or UEFI.

Older versions of the Linux kernel named IDE/ATA hard drives, and CD/DVD drives 
too, as /dev/hda, /dev/hdb and so on.

[gentoo-user] Re: Annoying structure of /var/db/pkg/category/package-name database

[Thomas Mueller]

Thanks to those who responded for the suggestions. 

I didn't think I sent this same message a second time.  If I did, it was 
accidental.

Using equery and other portage commands may be better than looking directly at 
/var/db/pkg/category/package-name, sort of like the new pkgng in FreeBSD 
which is taking over from the older format.


I come from a Linux distribution (Slackware) whose package management knows 
nothing about dependencies.

[gentoo-user] Annoying structure of /var/db/pkg/category/package-name database

[Thomas Mueller]

Having package data in /var/db/pkg/category/package-name carries the 
nuisance factor that finding a package involves a fishing expedition through 
many possible categories.

I am spoiled by having /var/db/pkg/package-name in NetBSD pkgsrc and FreeBSD 
ports, though FreeBSD is wsitching to a different structure nkwon as pkgng.

Is there any way to configure so as to avoid this annoyance in Gentoo?  Like 
maybe making /var/db/pkg/package-name?

One can do
ls /var/db/pkg/*/package-name but this is still an annoyance.

I have some limited experience with Gentoo Linux on my older computer.  
Compiling the kernel took 130 minutes, and then the kernel failed to boot.

Re: [gentoo-user] Emerging package via NFS ?

Hi,

just to let you know that approach below works for me.

I modified it slightly in that I add

mount --bind /usr/portage /mnt/other/usr/portage

to belows cmd list as machine A and B will always be synchronized.

Thanks a lot,

 Hi,
I'm curious if there's a way to capture the exact set of command
 that my machine executes as it boots up. I.e. - if I boot the machine,
 letting the boot loader find the kernel but then stopping at a bash
 prompt, before anything much has been done, I'd then like to know what
 set of commands I could use from that bash prompt to make the machine
 do whatever it does normally as it boots up.

Is that possible, and is it documented anywhere? Or instead of
 capturing commands maybe just a list of things that happen and the
 bash commands I'd use to execute them myself.

I think the init scripts, at least the ones I've found under
 runlevels, are more generic than I would like to run. I'm looking for
 something more like the portion of the install guide where we chroot
 into the new build, except executing that from the command line of a
 new machine that's booted. I.e.:

 mount /dev/hda4 /mnt/gentoo
 mount -t proc none /mnt/gentoo/proc
 mount -o bind /dev /mnt/gentoo/dev

 except modified to start from nothing and bring the machine up from
 scratch. Mount /proc, mount /dev, start udev, check root filesystem,
 etc.

This is totally for self-education and nothing else really. Just
 curious about how it happens, what order things happen, etc. If anyone
 can recommend a good _basic_ book that talks about this I'd appreciate
 it.

 the first thing I check, even when it seems irrelevant.

 Does your machine have a local hostname, and do you have an entry for it in

Just to let you know that I solved this (at least somehow) by using kdm

some more configuration/program-startup is done by kdm which solves this.
