Correct. You need to install sys-fs/fuse, as it contains the
library, some binaries and *OPTIONALLY* the kernel module. The
module will only be built, if the user has NOT built the module
in the kernel.

Install sys-fs/fuse :)

Hello Iain Buchanan,

Hey! ! was asleep! :)

As Alexander has already posted, you still need sys-fs/fuse to provide
the libraries, but it defers to the kernel for the modules (which saves
rebuilding it each time you change the kernel).

It also told you to remove lib{crypto,ssl}.so.0.9.7 after running those 
revdep-rebuild commands. revdep-rebuild finds that libssl.so.0.0.7 links 
against libcrypto.so.0.9.7 and the hack (preserve_old_lib from eutils.eclass)

[gentoo-user] XFCE automounting pendrive

[Alfredo Perez]

Hi

I was wondering what I can do to make XFCE to automount my
pendrive. I followed this wiki http://gentoo-wiki.com/HOWTO_ivman to the 
last word but still I can't have the my pendrive mounted.

I put an entry in /etc/fstab
/dev/sda1 /mnt/usb vfat defaults 0 0 and the pendrive gets mounted but as root 
which does not allow me to delete or create files on the pen because I dont have
permission.

Any more ideas?

Thanks

I don't think you did...

> I put an entry in /etc/fstab

Because it states

Ivman 0.6.x or greater uses pmount to mount your drives, and thus does
NOT need any fstab entries. However, fstab entries may still be used if
necessary, though you are suggested to avoid them when possible.

HAL/D-Bus automounters like ivman and KDE's built in system use pmount,
which works best without an fstab entry. If there is an entry in fstab,
it overrides the pmout defaults. In this case, it causes it to be mounted
as root rather than the user running ivman.

Hello,

I was also playing with ivman for a long time till accidentally I
stumbled upon this:
http://foo-projects.org/~benny/projects/thunar-volman/index.html.
Here's the minimalistic Wikipedia entry (copy and paste) that I've
made: http://gentoo-wiki.com/HOWTO_thunar-volman.

This is a light-weight GUI solution perfectly integrated to Xfce and
made by Benedikt Meurer. After installing it and enabled it in

Think this should be of help.

Pray tell, how does RAM manage to retain data when the power is off? 
It's either six transistors or one transistor and a cap per cell = not 
persistent.

I don't know of any magic persistent RAM that's fast enough for use as 
main RAM. Flash disks are of course another story but you do appear to

And, OTOH, it can install itself to other devices (but only the stage1,
stage 1.5 and/or stage 2 have to be already present on the target
device). So you can take a grub-enabled CD, boot it and restore your
system's hosed boot loader (say you just installed Windows or similar)
from the grub prompt.

Also, I prefer grub's "savedefault" features to the "-R" switch for
lilo (e.g. test boots w/ new kernels -- don't forget the "panic=..."
kernel parameter then!).

In theory, for the one transistor and one cap case, you have a loaded
cap that will take "forever" losing its load, won't it? But in
practice, I think, that's not realistic.

There actually are new RAM types being made for solid-state storage.
But this is in a proof-of-concept stage, I think.

Maybe Liviu's professor had those magnetic drum memory units in mind
when saying that?

Anyway, cleaning memory on a power-off shut down doesn't make much
sense. However, it makes sense to clean up memory after having critical
data in it -- e.g. a reboot doesn't necessarily clean up RAM. And I'm
not sure if some mainboards even keep the RAM powered in certain
situations -- at least, they can as long as the power is not really
switched off (e.g. machine only in ATX soft-off mode).

I think it's important to point out that if nobody ever ran the testing

in practice, the ram has to refreshed every few cycles (on reason why it is 
slow) because it is loosing its load so fast.

In practice, after power is cut, everything in ram is lost.

But not the stuff in swap

Considering that swap is encrypted, is it realistic for this "lost"
RAM data to be recovered? Again, take the case of a well funded

Definitely not realistic - the cap is on the order of a fraction of a pF 
and needs to be refreshed every 50-100mS or so. Once the power is off, 
the cap sees a (relatively) low impedance sink and discharges rather 
quickly

 I for one anxiously await the arrival of solid-state disks. 
I have customers who simply *cannot* do backups as the backup takes 
longer than the available window! Disk speed is a very limiting factor

[gentoo-user] grub problem

Hello people, i am having a little trouble with grub. I've just installed a
gentoo x86 (with intention of making it our first Gentoo powered server :D)
and after the install i get the error:

Filesystem type is ext2fs, partition type 0x83
kernel (hd0,0)/boot/kernel-genkernel-x86-2.6.22-gentoo-r8 root=/dev/hdb3

Error 15: File not found

I checked and the kernel name is right so any hints will be greatly
appreciated ;)

why:
/boot is where you mount (hd0,0) while gentoo is running, but while
grub is running you're starting from the boot partition's filesystem

Do you have /boot on a separate partition?  If so, you may need to
remove the /boot from the kernel line.  That may help.

How's your grub.conf? Did you remember to add the initrd?

Example grub.conf from the handbook:

timeout 30
splashimage=(hd0,0)/boot/grub/splash.xpm.gz

I'm basing myself mainly on:
http://gentoo-wiki.com/SECURITY_System_Encryption_DM-Crypt_with_LUKS#Encrypting_swap_for_installation
and
http://en.wikipedia.org/wiki/AES_process#Rounds_one_and_two

for the cipher's choice, and for the method used on:
http://www.gentoo.org/proj/en/hardened/disk-cryptography.xml

I have settled down to the following:
-c blowfish -h sha256 for swap
and
-c serpent  -h sha256 for the sensitive data partitions (/home, etc.).
in combination with a "strong" password.

How encrypted does this sound? For today, at least..

So, my eternal question, is it realistic for the "lost" RAM data to be
recovered? That is, after system shutdown, does the data still
physically reside on the RAM and can someone with a decent technology
and know-how recover it? In other words, is this a serious breach in
any encrypted system?

Aren't they both supposed to be OK? /boot/boot is a symlink to /boot, I 
believe the idea is that (hd?,?)/boot/ works regardless 
whether /boot is a partition or not.

Replacing /boot/ for (hd0,0) worked perfectly, ¡thanks a million!

It's actually not theory vs. practice.  Even in theory, it's not just a 
cap, it's a cap and a resistor.  So you have a time constant, tau = 
R*C.  Since the capacitance is very small (picofarads) and we're not 
talking large resistance either, you end up with a very small time 
constant and that cap leaks its charge very quickly (which is why the 
RAM needs to be refreshed and powered).

Thanks for the advice. Hopefully I can get enough functionality with
swsusp from gentoo-sources and so not need to change to
suspend2-sources - although that may be a very procedure?

Anyway I have created a 32GB SWAP partition (dev/sda5) and gadded
resume=/dev/sda5 to the boot options. And also made the suggested
change to /etc/acpi/default.sh in point (4) above. Now when I press the
soft power button the system suspends ( all processes appear to stop
and the screen goes blank but for a flashing cursor in the top left of
the 2 screens of my dual headed system) but after a few minutes the
system resumes. It seems that either a wakeup message is being received
or the hibernate script cannot actually power off the computer and so
after a timeout period it resumes.

Ok, I had read it that I did _NOT_ need sys-fs/fuse.  I will re-emerge fuse.

Are we missing the obvious?  The easiest think to 'break' is the weakest link 
in the chain.  In such a *hypothetical* case that would be the person who is 
in possession of the passphrase.  I would expect that such a person would be 
invariably labeled a "hacker" and condemned to eternity . . .

Cracking the encryption algorithm by computation would only be necessary if 
the said person was not able to disclose the key due to absence, or due to an 
inability to recover from the vegetative (or worse) state that the 
questioning methods may have inadvertently induced.

 :P

Was your /boot mounted when you installed grub?  Check the Installation

Weird, as far as I remember, I've always had the correct symlink and boot on a 
separate partition... No matter, thanks a lot for the explanation, that

Just to explain a little further, the stage file creates /boot and 
/boot/boot. Thats fine if you want /boot on the / partition. If you want 
/boot on a separate partition, you need to mkdir /boot and mount that 
partition on /boot BEFORE you untar the stage - or create the /boot/boot 
symlink manually.

how about adding the snapshot svn ebuild request for synce-* packages?
http://bugs.gentoo.org/show_bug.cgi?id=157868

since there are lots of updates happening at the moment in svn, these
would be much nicer than the 0.10 release :)

AFAIK, they haven't been updated for xorg-7.3, but I don't follow the
legacy drivers.  But cardoe says that nVidia says the drivers do work
with xorg-7.3 with a little tweaking (including turning off the
composite extension).
