Yes, that might have been a problem. I got tired rebuilding the same
packages over again and adding with each new version "abi_x86_32" flag
to package.use.
I just added to make.conf
ABI_X86="32 64"

After upgrading several 1-year old systems I think best approach is to
make a backup of "world"
emerge -C world
Restore the world from backup and do emerge world

Apology Alan, but this still isn't very clear to me.
Yes, I did check with "eix nano" and it showed that I had latest version
installed.

Even "emerge -Ca nano" showed I had no prior version installed.
So am still confused why is it has "-> 2.3.1-r2"

I figured it must be a pointer to an older version but since I had a
newest version installed why pointer to an older version?

man eix only shows "eix-test-obsolete" is equivalent to eix -tTc

There's the problem, you have enabled the abi_x86_32 USE flag for all
versions of udev and the libudev virtual, bit only for one specific
version of eudev, so the only way portage can upgrade virtual/libudev is
to install udev, which conflicts with eudev. Fix package.use to the
entries for libudev and eudev match.

Michael O. is spot on.  Drupal 8 is more of a framework for developing 
websites.  Wordpress is less of a development workhorse, but will give you an 
acceptable website relatively effortlessly.  This is one of the reasons many 
people use it for blog sites.

Two quick points on the ease of maintenance between CMS':

Some ISPs offer a GUI-fied update facility for Wordpress, whereby you click a 
button and the latest core installation and modules are updated for you.  I 
have also seen this with Drupal, but less frequently and the version offered 
by the ISP may not be the latest one.  So with Drupal, updates have always 
been a manual exercise for me.  Drush, a CLI tool, simplifies Drupal 
maintenance for those who are not limited to point & click computer 
operations.

Depending on your website development needs you may need more than one site.  
A production site and a development site is a typical minimum requirement. 
More active sites have prod/pre-prod/dev/testing versions.  This means you 
will be exporting database content and importing it from one site to another.  
Unlike Drupal where exporting and importing database dumps is a straight 
forward activity, with Wordpress you will need to change some of the database 
content manually before you import it.  This is because Wordpress uses 
serialised PHP arrays and hard-codes URLs in the database cells and its 
upgrade.php scripts do not deal auto-magically with database migration.  There 
are 3rd party scripts and plugins to deal with this, but it is an additional 
step and a manual exercise:

https://interconnectit.com/blog/2009/10/07/migrating-a-wordpresswpmubuddypress-website/

If you only have one production version on a single domain/webroot this 
problem does not apply, but I raise it here because you mentioned you may be 
foisting the responsibility for this website on someone else, less technically 
competent than yourself.

Many SD cards are optimized for FAT usage, thus they do wear leveling
only where FAT systems do most writes and rewrites: In the file
allocation table. Almost anything else works different.

Maybe better try f2fs as it more likely spreads writes evenly across
the SD card.

Interesting. Another contributor, another opinion. :-)

I already have books on WordPress and Joomla, and I've just ordered one on 
Drupal. Then I can take my time experimenting and comparing.

Thanks again to all. I'm certainly learning today.

This is not the recommended approach.  Use /etc/grub.d/40_custom to add any 
bespoke entries.  However, the GRUB2 OS-prober should pick it up on its own.

It may be worth re-installing GRUB2 in case something has gone askew, or 
booting from a LiveCD and running GRUB from there to find out what it sees, in 
case your GRUB installation is corrupted.

Choosing a CMS is a textbook example of "pick your poison." We usually 
go with either Wordpress or Drupal.


The design of Drupal is much better, technically. Every feature is part 
of a "module" that you can turn off. The API is well-documented, and 
it's easy to write new modules. A "content type" in Drupal is a thin 
abstraction over a database table, and you can build pretty much 
anything you want by creating the right content type and then creating a 
"view" to display it how you want.


The end result can be nicer for end users; for example, you can give 
them a button to create a new employee, or a newsletter, or a blog 
entry... and each one of those content types will have separate fields 
and a separate UI. The trade-off is that nothing works out-of-the-box in 
Drupal, and it will take you two weeks to get all of that set up.


With Wordpress, you get a nice, clean, easy-to-use site in about five 
minutes. If that site will work for you -- i.e. if all you need is 
pages, menu items, a contact form, and whatever else you can get from 
pre-existing plugins -- do that!


Wordpress is made for non-technical users but I don't mean that in a bad 
way. I've been doing Wordpress updates on some sites for over five 
years, and it's never crashed and made me stop what I was doing to fix 
it. Plugin updates are similarly easy, but I can echo what Mick said: 
you need to pay attention to the update notifications, and they come 
frequently.


All CMSes have terrible security records, so the fact that Wordpress 
gets hacked all the time shouldn't lead you to believe that another CMS 
would fare any better. You can make any CMS a lot more secure in two 
simple ways:


  1. Always update ASAP.
  2. Don't make your website writable by the anonymous web user.

The second one means that you will have to update over SSH, at least as 
long as you maintain the site, but severely limits the damage that a 
hacker can do with a tiny exploit.

You could also check out Scaleway, who offer a dedicated ARM server for 3

I don't have mate installed any more to test, but did you try pressing Alt+F2

Failing this I think Ctrl+Alt+t should launch a terminal ...

Hi Stroller,

I use Linode for my cloud web and email server.

It was very easy to set up and has not had any downtime since it was set
up (a year or so ago.)

I don't use the web gui for access much (generally only for DNS
management which they do well also.)

Though I've used the lish console accessible from the GUI.

I recommend them!

the sdcard itsself is ok and "only" the logical structure

Or do I overlook something?

The dd gets you the best chance to work on the data before it completely
fails.  In my experience the sdcard will only get worse ending with total
failure - if it hasn't already.

If the dd dump comes up rubbish and cant be recovered, the actual sdcard
will be worse.  You can run "strings" against the image to see if there is
any text in there (or even cat the /dev/sdcard node through strings) to see
if the bits are still there.

I dont know of a cdparanoia type recovery utility for sdcards but I suspect
sdcard design means that approach wont work.

BillK





Hi Bill,

I got mixed results: There are three partitions on the sdcard from
which I could fully recover (even mount it directly via loop device)
the first and the third one.

The second one is screwed up.

Running fsch.ext4 against the image it starts with "bad superblock"
and suggests two alternatives.

I started fsch.ext4 again while using -b to define the alternate
superblock and it starts to ask me *zillions of question, which
I all answered with 'yes' in a first attempt (I have a backup of the
image...).
The result was an image, which I could mount again.
But beside 'lost+found' with some small rests of something which
may be files in a previous life nothing was there

Currently it looks to me, that something has totally messed up the fs
there.

What do you think?

Cheers
Meino






Sounds like its toast :(

I have never had a lot of luck with any of the ext file systems - you have
to baby them and they corrupt very easily compared to others.  I try and
avoid them ...

BillK





Hi Bill,

...the SDcard is for my Android tablet, which runs kernel 3.6.x.something 
(Lollipop)
if I remember correctly. With the App Linux Deploy I installed Linux
on another partition of the sdcard and used to chroot into it.

With what filesystem did you made good experiences of, Bill? My GENTOO PC
(with which I am currently writing this email) also uses ext4...and
your last mail makes me nervous...very nervous...

For my tablet I have to use an filesystem, which is supported by and
compiled into the kernel. Unfortunately, there is no alternative
Android build for this tablet...
In this case it is ext4 and vfat...and of that both I think ext4 is
better...

Cheers

I used to prefer reiserfs ... more robust in some ways, less in others

not perfect but with OS disks are single and the rest are bcache/ssd 
fronted  btrfs raid10's my main issue is running out of space.


Problems with the ext series were inability to deal with dirvish backup 
(corrupted), running out of inodes, terminal corruption when running out 
of space, silent corruption with hibernation, data loss/corruption on 
abrupt power loss, and it goes on ...



Current sdcards are either vfat for win compatibility (no choice) or 
btrfs (raspberry pi).  Just turned off my older rpi model 1B which is 
ext 4 earlier this morning - been corrupted and reimaged a few times!


File systems seem to be very much YMMV - each use, load and environment

Some years ago I had to revive a removable drive that someone had repeatedly 
snatched out of the machine without unmounting it first. I tried photorec 
and pals and had the same impenetrable maze of unhelpful file names as 
Adam's. I know it's not much help, but I eventually found another utility 
that just swept through and put everything back together again, humpty-
dumpty fashion. I wish I could remember what the utility was. Sorry. But it 
is out there somewhere in Google-land.

Re: [gentoo-user] The sudden disappearance of ....WHAT??? (I/O error on a SD flash card?!)

[Fabio Scaccabarozzi]

Hi tuxic,

That looks like an output from photorec. Generally photorec only reads the
whole disk block by block, when it finds information in the filesystem's
metadata - either inode table or inodes themselves - you're lucky and you
get filenames, otherwise you only get that kind of output. Consider that
all those items might as well be deleted items, so you might be getting
back a lot of cruft.
I never had to use the functionality so I cannot comment on how good it
works, but testdisk allows you to restore partitions by scanning the entire
disk/image searching for superblocks and partition metadata. That might
give you a chance of restoring the superblock of the partition and
salvaging at least some part of the data. See a guide on testdisk's
official website -> http://www.cgsecurity.org/wiki/TestDisk_Step_By_Step
Consider that by default ext4 partitions should have superblock backups
spread out at fixed intervals during the filesystem creation, so this
should work better than trying to blindly carve the data out of the
partition.
Before applying fixes to the image file make a backup in case something
gets screwed up :-) Testdisk might detect additional stuff that looks like
partition info, but it's not.

Run tcpdump -w on both sides. Compare dumps when connection stalls
and when it works fine. Many reasons are possible, it's hard to

And yes, its a real pain to loose the filenames!

I keyworded x11-misc/sddm-0.14.0-r3 and discovered enlightenment complains
it can't run the compositor with OpenGL.  I tried starting a X session
from the console without DM, with 'startx /usr/bin/enlightenment_start'
but I also get similar symptoms, including inability to run compositor
with OpenGL.  I get errors like this in ~/.xsession-errors:

I also tried entrance from bar overlay (it has not been updated in a while
and has a dependency on an obsolete package), slim (won't log me in) and
lightdm. When I run lightdm there are no such problems, enlightenment
starts with OpenGLcompositor, I can mount USB disks, but lightdm
installed and is running much more than what I really need for my
desktop.

Is there a way I can start enlightenment without running into all these
kind of errors?  Can you see something wrong in my file contents above?

Your files look OK to me so I have no idea why you get those erro.

You also say lightdm wrks correctly, so lookee here:

alan@khamul ~/gitwork/ansible $ equery size lightdm
  * x11-misc/lightdm-1.21.5
  Total files : 119
  Total size  : 1.91 MiB
alan@khamul ~/gitwork/ansible $ equery size sddmdm

  * x11-misc/sddm-0.14.0-r2
  Total files : 192
  Total size  : 4.78 MiB

The on that works is smaller and lighter than the one that doesn't.

I say dump sddm and stick with lightdm which works :-)


Yes, the thought crossed my mind.  ;-)

It is smaller as a package as you noted, but it is running gnomey stuff like
/usr/libexec/accounts-daemon, /usr/libexec/gconfd-2 and perhaps
/usr/libexec/at-spi-bus-launcher, which I am not sure I need.

Either way, if I were to start enlightenment with startx and skip using a DM
altogether, is there a way of starting enlightenment and ensuring it has the
appropriate access rights to run udisks2 and OpenGL?




You'll probably get better answers over at the enlightenment user list.

Drupal 8, which is the current version under active development, requires 
updating the core installation once every couple of months on average.  You 
may need to also update the odd drupal module every couple of weeks.

Wordpress core also requires updating every 2-3 months, but Wordpress modules 
require updating on a weekly basis.

Of course the above is a generalisation and 'your mileage may differ' 
depending on the amount of modules you install to provide the desired 
functionality on your website.  In my experience Wordpress has a higher 
workload to keep going without getting hacked.  The Gentoo devs are waving 
around garlic and crosses for good reasons.  Wordpress has a bad reputation 
for being easily hacked, but this may also be because a lot of Wordpress users 
install and forget with the inevitable dire consequences.

In either case it is best you register with necessary mailing lists to receive 
security announcements and run immediate updates, or apply workarounds, when a 
vulnerability is revealed.  With script kiddies and state actors at it, it 
doesn't take long before you lose control of your installation these days.

However, for websites which are to be maintained by non-technical users I 
would recommend one of many ready made solutions provided by web hosting ISPs 
like https://www.weebly.com.

Hi,

I copied the image of course and umounted the sdcard as soon as
possible.

As in my previous posting, as long the recovered files are images,
the lost of filenames my be annoying...
But in case of files of a Android system (from which the sdcard
originates) the lost of filenames is equivaltent to the lost of
the file itsself...

I've run it up, and things certainly have moved on since the MRTG days!

However, it doesnt seem to give things like IP addresses, routes etc. I'm

quickly dump the layer3 network info, by clicking on the device link.

Gives me a lot of files with unrelated names.
Think of your GENTOO box with all names renamed
to something like

[index number].[filetype]

. So you got back your data but cannot use
it, since the names got lost.

For images this is not a big deal...display them
and you know probably how to rename them back
to something useful.

But what file is (for example)

-rwxr-xr-x   1 root root   4083 2011-11-22 03:46 file002873.bin

which is located somewhere in the Marianna trench of an Android
system???

Hm...

Currently I am playing with different kinds of "get lost" it seems...

Hi Bill,

...the SDcard is for my Android tablet, which runs kernel 3.6.x.something 
(Lollipop)
if I remember correctly. With the App Linux Deploy I installed Linux
on another partition of the sdcard and used to chroot into it.

With what filesystem did you made good experiences of, Bill? My GENTOO PC
(with which I am currently writing this email) also uses ext4...and
your last mail makes me nervous...very nervous...

For my tablet I have to use an filesystem, which is supported by and
compiled into the kernel. Unfortunately, there is no alternative 
Android build for this tablet...
In this case it is ext4 and vfat...and of that both I think ext4 is
better...

In that case its photorec time against the copy of the image (see previous
note about only working on a copy - the changes that fsck makes may
compromise photorec's efficacy). Probably worth reading the testdisk and
photorec man pages first.

I hope you meant to say "mount the sdcard image". Once ddrescue has done
its best, you wont try to use the sdcard again.

Also, you probably want to copy the image first, because when you try to
fix it you will perform writes, and you dont want to lock yourself out of
other recovery options by making potentially damaging writes.

If ddrescue can read it cleanly with no retries (in which case it will
offer no benefit over dd) then yes, I agree. However, given the cost of a
card and the cost of your time and the risk to your data, I wouldnt be
using it.

I would just use photorec against a copy of the image. I have done this in
the past and recovered many files from a ddrescued image of a failing USB
drive, however, all the filenames were lost.

[gentoo-user] Strangeness with Grub and Win7 partitions

[Andrew Lowe]

Hi all,
	Don't know if it's my machine or a bug somewhere in Grub, but I have a 
dual boot setup /dev/sda - Linux, /dev/sdb - Win7, that grub-mkconfig 
would find correctly and build the grub.cfg file for. Or it did in the past.


	I hadn't had call to boot into Win7 for a while but kept building Linux 
kernels and running grub-mkconfig. Linux always booted correctly but 
recently upon trying to boot Win7 it failed. Investigation shows that my 
Win7 partition isn't being found. Manually adding it to grub.cfg fixed 
the boot problem.


	I have not changed anything in the way I run grub-mkconfig, I have 
os-prober installed and when booted into Linux can see and use any of 
the partitions in the Win7 install, ie ntfs3g is installed and working. 
Does anyone have any ideas as to what's going wrong?


Thanks,

Andrew

The dd gets you the best chance to work on the data before it completely
fails.  In my experience the sdcard will only get worse ending with total
failure - if it hasn't already.

If the dd dump comes up rubbish and cant be recovered, the actual sdcard
will be worse.  You can run "strings" against the image to see if there is
any text in there (or even cat the /dev/sdcard node through strings) to see
if the bits are still there.

I dont know of a cdparanoia type recovery utility for sdcards but I suspect
sdcard design means that approach wont work.

BillK





Hi Bill,

I got mixed results: There are three partitions on the sdcard from
which I could fully recover (even mount it directly via loop device)
the first and the third one.

The second one is screwed up.

Running fsch.ext4 against the image it starts with "bad superblock"
and suggests two alternatives.

I started fsch.ext4 again while using -b to define the alternate
superblock and it starts to ask me *zillions of question, which
I all answered with 'yes' in a first attempt (I have a backup of the
image...).
The result was an image, which I could mount again.
But beside 'lost+found' with some small rests of something which
may be files in a previous life nothing was there

Currently it looks to me, that something has totally messed up the fs
there.

What do you think?

OK. I'm installing Drupal now. I only chose Joomla after a good deal of

Pelican looks interesting; I may follow it up. I didn't say this before (one 
thing at a time, eh?) but I need to build a site that another choirman can 
take over from me at some time. That seems to rule out anything that smacks 
of script writing, because as far as I know, nobody else has the slightest

I notice that no-one has mentioned WordPress. I had a look at it, but was

From what I recall I could click on the desktop and type a 
command/application.  Plasma also has something similar.

Hi Bill,

I got mixed results: There are three partitions on the sdcard from
which I could fully recover (even mount it directly via loop device)
the first and the third one.

The second one is screwed up.

Running fsch.ext4 against the image it starts with "bad superblock"
and suggests two alternatives.

I started fsch.ext4 again while using -b to define the alternate
superblock and it starts to ask me *zillions of question, which 
I all answered with 'yes' in a first attempt (I have a backup of the 
image...).
The result was an image, which I could mount again.
But beside 'lost+found' with some small rests of something which
may be files in a previous life nothing was there

Currently it looks to me, that something has totally messed up the fs
there.

What do you think?

Cheers
Meino

ddrescue is probably a better option than plain dd.

step 2: put the sdcard to one side.

step 3: loopback mount a copy of the image (not the original)
step 4: try recovering the filesystem on the loopback, if it fails ... try
something else on another image copy



Yep, once you've got the image mounted loopback, you can run
testdisk/photorec depending on how bad it is.


Hi all,

thanks a lot for all help! :)

Currently I am ddresucueing the flashcard to the harddisc.
Next I will try to mount the sdcard.

What reliable sdcard-reader can one recommend ?

Hi,

Is the assumption correct, that -- if ddrescue could read each
partitions of the sdcard without stuttering, retries and errors --
the sdcard itsself is ok and "only" the logical structure
(fs, superblock etc) got damaged?
Or do I overlook something?

(Background: I dont want to put a sdcard into the bin, if
fdisking & reformatting that beast would gives me back an ok
media...)

The dd gets you the best chance to work on the data before it completely 
fails.  In my experience the sdcard will only get worse ending with 
total failure - if it hasn't already.


If the dd dump comes up rubbish and cant be recovered, the actual sdcard 
will be worse.  You can run "strings" against the image to see if there 
is any text in there (or even cat the /dev/sdcard node through strings) 
to see if the bits are still there.


I dont know of a cdparanoia type recovery utility for sdcards but I 
suspect sdcard design means that approach wont work.
