Backup with tar;
1. boot from cd
2. mount /dev/sda1 /mnt/boot
3. cd /mnt/boot
4. tar czf /otherdisk/boot.tar.gz *
5. mount /dev/sda3 /mnt/root
6. cd /mnt/root
7. tar czf /otherdisk/root.tar.gz *

Restore;
1. Boot from cd
2. fdisk /dev/sda
3. mkfs.ext /dev/sda1
4. mkswap /dev/sda2
5. mkreiserfs /dev/sda3
6. mount /dev/sda1 /mnt/boot
7. cd /mnt/boot
8. tar xzf /otherdisk/boot.tar.gz
9. mount /dev/sda3 /mnt/root
10. cd /mnt/root
11. tar xzf /otherdisk/root.tar.gz (should i exclude anything? /proc /sys?)
12. chroot /mnt/boot
13. grub-install --no-floppy /dev/sda

[gentoo-user] genkernel without oldconfig

[Daniel D Jones]

Is there any way to run genkernel without it running the oldconfig command?  I 
can work around the issue by saving my .config file to a different name, then 
using --xconfig and loading the saved file but it would be nice to just tell it 
not to alter the existing .config file.  It may be that I'm just missing it but 
man pages and Google have not provided a solution.

Yes, the configuration file has an appropriate option:

# Run 'make oldconfig' before compiling this kernel?
OLDCONFIG="no"

[gentoo-user] Yahoo and strange traffic.

[Dale]

Hi folks,

I been noticing the past few weeks that something is communicating with 
Yahoo at these addresses:


cs210p2.msg.sp1.yahoo.com

rdis.msg.vip.sp1.yahoo.com

I thought it was Kopete getting some info, profile pics maybe, from the 
server.  Thing is, it does this for a really long time.  It is also 
SENDING data as well.  I have no idea why it is doing this or what it is 
sending.  I closed the Kopete app but the data still carries on.   This 
"transfer" has been going for a while now and the only way I can stop it 
is to stop the network, wait a minute or two for it to time out and then 
restart the network.


Anybody have any idea what the heck this is?  Is Yahoo up to something?  
Some new security issue that I haven't heard of?


Thanks.

Dale

I think it's normal.

The first address is one of their pool of messaging servers and the
second is a web server, probably like you said for retrieving
additional info. The sending of data could be the http request, or
updating your status/picture/whatever kopete may be doing. You could
try blocking it and see what breaks. :)

Likely true as Yahoo!'a interfaces are highly AJAX driven - with their own PHP 
oriented widget kit as well.
So if you have a web page open to any Yahoo! site that is probably what is 
doing 
it.

Dale,

It could also be a weather map, or any number of widgets that get data from 
the intartubes.

netstat with -p can help track down the app that has the connection open

What does your netstat show with respect to ports being used and what does 
tcpdump/tcpflow show?  If it is Yahoo, you should see things that are relevant 
and hopefully make sense.

Wouldn't it stop tho if I closed Kopete?  I'm not using Yahoo's 
messenger tho.  I don't think they have one now.


I did also trying closing Seamonkey to but the traffic continues.  I 
very rarely go to yahoo.com.


Also, this can carry on for a really long time.   This can last over 30 
minutes.

[gentoo-user] How to build a time machine on Gentoo

[Nganon]

Hello all,

My first post on the list. I thought I would start with something that I
started
to think of as 'essential' after losing 90GB of data. Now I have two main
questions in mind: what to and how to back up on gentoo most efficiently.

1. Apart from users' home directories and the followings, what should be
backed
up on a gentoo machine?
/etc/portage/
/root
/var/lib/portage
...?

2. Erm..okay, I am gonna say, what magic I want and then ask your way.
I first started making gzipped tar balls as follows:

tar czpf /media/backups/userA-`date +%Y.%m.%d`.tgz -X userA-excludelist /etc

But these can get huge especially for home dirs. I also want safe dvd
copies.
Though I can find enough space on the external drives, I don't trust them
any more. See above..sigh..(No I recovered about one third of it with
testdisk/photorec
which names them as file01 file2.. and half them are zero sized..
which
quite justifies my agony)

Here is what I wanna do. I want to have only one big backup for, say,
userA-2010.08.07.tgz and other small backup tars containing only the
files/folders that were modified since last update, 2010.08.07, as
userA-diff-2010.08.14.tgz, userA-diff-2010.08.21.tgz,
 userA-diff-2010.08.28.tgz
etc. Now if I want to take the userA back to the future, 2010.08.21,  I want
to
do it by first extracting the huge tar userA-2010.08.07.tgz and then the
tiny
backup userA-diff-2010-08-21.tgz.

But the thing is I don't know how to do this. I am hoping maybe you can tell
me
how to of it as well as a better way of doing backups.

By the way, since I want dvd backups as well, and I want to use +rw dvds so
I
can overwrite old backup after a while, what is best way of ensuring the
integrity and safety of them. Is it a good idea to use truecrypt containers?
Or
nothing tops signing and encrypting with gpg?

Thanks for any comment in advance.

Wouldn't it be easier to just backup the whole / directory?
Excluding /home, /usr/portage and /var/tmp/portage?

Okay, but I don't trust DVDs. Although DVD-RAM is quite safe I heard.
But external disks are flexible, offer more space, and if you want more
security, just use yet another drive, so you are safe even if your main
drive and a backup drive fails.

I suggest you have a look at rdiff-backup. It gives you a 1:1 copy of
the source directory, but also does incremental backups, which are
stored (in compressed form) in an additional folder in the destination
directory. I would use this at least for things like /etc, where I
sometimes might want to retrieve an old version of a file. Similar to
your approach with big tar files and small ones containing the
increments.

I use a script for my backups, which I mentioned here on 2010-05-07,
subject 'Snackup'. It optionally creates LVM snapshots so I can make
backups from the running system, even if the source directory is
altered during the backup. This works on LVM only, though, and also
allows the volume to be LUKS-encrypted. It does backups by rdiff-backup,
rsync, cp, tar or dd. It may be overkill when not using the LVM
features, but still I suggest to use some script for backups, so one
does not always have to remember the backup commands. When I want to
update my backup, I enter something like 'snackup boot root home src',
and the script backs up my boot, root and home partition in the
background, and creates tar files each directory in /usr/src.

I'd use DVD-RAM. The media is a little more expensive, but AFAIK they
were made with long-time backups in mind. And access is much easier,
you just copy the files as to an external drive, no need to burn ISOs.

[gentoo-user] emerge xchat fails

[Daniel D Jones]

I have xchat installed.  An update is failing to install with error:

libtool: link: cannot find the library `/usr/lib/libpng12.la' or unhandled 
argument `/usr/lib/libpng12.la'

libpng is installed:

/usr/lib$eix libpng
[I] media-libs/libpng
 Available versions:  
(1.2)   1.2.44
(0) 1.4.3
 Installed versions:  1.2.44(1.2)(06:16:49 PM 07/01/2010) 1.4.3(06:15:21 
PM 07/01/2010)

Checking the lib directory, I find:

/usr/lib/$ls libpng*
libpng12.so.0  libpng14.a  libpng14.la  libpng14.so  libpng14.so.14  
libpng14.so.14.3.0  libpng.a  libpng.la  libpng.so

Any suggestions on how I go about fixing this?

To expand on Dale's answer, Handbrake is unlikely ever to be in Portage.

The Handbrake developers use the poor practice of snapshotting the  
upstream libraries they depend upon (I'm not sure if they also patch  
or modify them, instead of pushing those changes upstream) and then  
packaging those libs with Handbrake (in a particularly ugly way, too,  
one might add).


So when you install Handbrake you download a bunch of additional  
libraries (which you likely already have installed on your system) and  
it is compiled against those versions.


The correct way to do this would be for the handbrake developers to  
simply specify which libraries are required and link against the ones  
already installed on your system. If a specific version of a library  
is required - but generally speaking it shouldn't be - then that can  
be done as part of the ebuild / makefile dependency checking.


The link you posted to handbrake-0.9.4.ebuild is an ebuild. You can  
install it something like this:


# mkdir -p /usr/local/portage/media-video/handbrake/
# curl http://bugs.gentoo.org/attachment.cgi?id=229397 > \
 /usr/local/portage/media-video/handbrake/handbrake-0.9.4.ebuild
# ebuild manifest /usr/local/portage/media-video/handbrake/ 
handbrake-0.9.4.ebuild

# emerge handbrake

It's a shitty ebuild, and it has to be, because that's inherent in the  
way the Handbrake devs "package" their program, but the ebuild does  
install and work the way the Handbrake devs intended.


I would have thought you'd already know this if you had fully read bug  
#89432.


I know that transcoding is a bit of a black art, but I'm not convinced  
Handbrake is actually that good.

Have you run:

# lafilefixer --justfixit

It looks like the libpng update has removed /usr/lib/libpng12.la and
/usr/lib/libpng.la is probably referencing this file. lafilefixer should
fix this.

You're running with both libpng 1.2 and libpng 1.4 installed. May I
suggest you read:

http://blog.flameeyes.eu/2010/06/29/stable-users-libpng-update

Do you keep a log of emerge messages so that you can fix these issues
as they arise?

The file /usr/share/portage/config/make.conf.example gives examples of
how to store all messages generated during an emerge update. These
messages can save you a lot of grief later on.

Now I'm curious.  Basically the programmers have a crappy way of making 
their package and Gentoo doesn't need the headache?  Based on your 
explanation, I can't blame the Gentoo devs for that.   They got enough 
headaches already.


I also noticed that bug report was started about 5 years ago.  I really 
think you are right that it won't ever be added, unless the people at 
handbrake do things differently.


Didn't Googleearth start out this way tho?  I know it used to be a huge 
mess.

I might have, but reading 111 comments about a package I've never seen is
more than my brain can do,
but I had suspected something like the result: not gonna happen.

Well, I'm a newb in video, but it was suggested to me by someone who uses
it, so I wanted to try.

My underling thing, if anyone can make other suggestions, is that my camera
broke, and I had to get
one in a hurry, and didn't really know what to look for.  I wound up with a
fairly good Sanyo 1080p camera
and video recorder that's super light, and not too expensive.  The problem
is that its videos are MP4s,
which are definitely not ready to put on a web site, and I know nothing
about transcoding.   My previous
camera took acceptable .avi videos, which had worked with most folks
browsers.  The MP4s are huge
and in a weakly supported format.

I'm somewhere on the learning curve, obviously, but having trouble getting
coherent advice.

Mplayer comes with a program called mencoder, which will do your video 
encoding. Its a bit more "hands on" but it is excellent once you learn it.

IIRC, isnt MP4 just a container? what are the video codecs and audio codecs in 
the file? If they are 264 and mp3, you should be able to use HTML5 for them 
natively. 

MP4 is actually gaining alot of support in many OSes due to it being part of 
the HTML5 spec. 

If you need help with video transcoding, i'm happy to assist you as it makes up 
a small part of what i do in the work place. Just send me an email. 
(inde...@internode.on.net)

The basic run down is that you have a container format, that holds an audio and 
video stream. the container, has no part to play in what the video or audio 
codecs are, only the storage of subtitles and other metadata. 

Generally, with a program like mencoder you would use mencoder -vo  -ao  -o file.

In the majority of cases, it is the video codec, not the container that holds 
the issues, especially with the use of weird video codecs. (such as myself who 
is fighting with someone convinced they want to use real video still .)

Thus if your camera is producing MP4, you should find out what video and audio 
codecs it is outputting. This can be done with mplayer from the command line, 
as when it opens a file it gives output similar to this

bash-3.2$ mplayer /Volumes/Storage/Videos/Butterfly_Total_Remix_Pro.flv

The sections you are interested in, are between the   signs. They tell you 
it is a Flash video, with MP3 audio. You can also see it is a flash container. 
It may be worth running one of your videos with mplayer to find what codecs
