encrypted partition tools?

[yoshi314]

i've been wondering about that for a while now;  is there a package for cryptsetup + crypto kernel modules for TCL, and LVM somewhere? i can't seem to be able to find it via appbrowser.

We have loop-aes support in the 2.x series; cryptohome isn't supported anymore, but you can encrypt files and partitions fine.

Util-linux-ng for the user-space tools, and tripl for easier setting up if you don't wish to go manual.
Besides AES, Blowfish, Twofish, and Serpent are available in loop-aes-extra.tcz.

[yoshi314]

is it (loop-aes) compatible with existing encrypted partitions created with cryptsetup?

my entire hdd is encrypted, so i'd like to access it somehow from TC :]

[curaga]

I don't think so. Never used dm-crypt though, don't quote me on that.

[yoshi314]

all right then. i guess that means i have to build my own kernel, device-mapper, lvm and cryptsetup.

it's surprising nobody needed these so far.

[curaga]

Actually, only the lvm/dm modules are needed, if you don't want to build it all.

[yoshi314]

and crypto ones, too.

i'm already experimenting with replacing the kernel in TC, and it doesn't look too bad. but it throws up a lot of warnings though :]

[yoshi314]

sorry for double post.

it turned to be quite lucky - kernel has crypto support and i just had to install mdadm (for dm-* modules), some development packages and get lvm + crypsetup compiled. now i can access my encrypted partitions properly from TC.

i hope somebody will package those two tools, as i'm sure i'm not the only person that could use them. i might try, after i experiment with packaging in TC for a while.\

edit: it seems TC is missing ext4 support. aww crap

ext4 is supported through the filesystems-2.6.29.1-tinycore extension.

[yoshi314]

yeah, i found it a few minutes later

i'd better read up on packaging for TC tomorrow.

btw where do we report bugs with packages?

[Jason W]

The tce bugs area is best.

I'm very interested in having LVM support in tinycore.  I'm planning to use microcore as a PXE-bootable install/maintenance image.  I've bundled in rsync, etc., but I still need LVM support.  Please post a note on the forum if you create packages, and thanks in advance.

i did, but it's far from proper. but hey, at least it works (for me, that is) ;-)

it's LVM + cryptsetup packaged together (that's what i meant by far from proper). i still have them packaged separately in .tar.gz packs if somebody needs them.

you need to create .md5.txt for it.  i assume this is absolutely required by tce loader.

Code: [Select]

md5sum lvm.tcz >> lvm.tcz.md5.txt
i don't think this needs any special dependencies.
you need mdadm package because of dm* kernel modules it contains.

Beautiful!  This works great!  I've dropped your lvm.tcz into /opt/tce/optional along with:

Code: [Select]

gcc_libs.tcz
mdadm.tcz
md.tcz
openssh.tcz
openssl-0.9.8h.tcz
popt.tcz
rsync.tcz

and their respective md5 files, then created links in /opt/tce, pointing to the tcz files in "optional".  I re-made the image with

Code: [Select]

find | cpio -o -H newc | gzip -2 > ../microcore-rsync.gz
and everything works!  Thanks so much.

cool. i remember that popt was a build dependency. i didn't expect it to be a runtime dep. or maybe i was thinking about some other package

aaagh, nevermind that :]
