Need Help With Captive-ntfs on Suse 9.3

koy · 08-14-2005, 03:45 PM

Well i found this captive program and thoguht I'd might give it a try to mount my windows hdd as rw

So I installed the rpm, worked perfectly, ran the install-acquire, and it fetched the ntfs file from the sp1.
But I still get an error when mounting:

Code:

linux:/usr/share/lufs # mount.captive-ntfs /dev/sdb1 /mnt/captive-noname2
Captive NTFS v1.1.5.  Check a new version at: http://www.jankratochvil.net/
Preparing LUFS kernel module... Run /usr/share/lufs/prepmod if problems occur.
lufs module not loaded: Try running /usr/share/lufs/prepmod to see more. at /usr/bin/captive-lufsd line 180

and when I run /usr/share/lufs/prepmod it gives me this:

Code:

linux:/usr/share/lufs # /usr/share/lufs/prepmod
+ /sbin/modprobe lufs 2>/dev/null

My kernel sources are installed correctly though.

Here's my fstab btw:

Anyone have an idea of how I could fix this? I'm sure it's something simple, maybe some file which should be copied to a different dir or smth.

P.S. "modprobe lufs" gives me:

Code:

FATAL: Error inserting lufs (/lib/modules/2.6.11.4-21.8-smp/kernel/fs/lufs/lufs.ko): Invalid module format

I searched a bit on google and someone said that you need to type the following to get it working under suse 9.2:

"make cloneconfig modules modules_install" so I did that (inside of /lib/modules/....) and now the error message is slightly different:

as you can see, it's actually compiling or doing something to the files, but then stops without a detailed error message :/

P.S. "modprobe lufs" now gives me:

Code:

i reached this page several times finding a way to solve this thing....
so i figured others too will reach this page & i m posting the solution here..
we are going to tweak some stuff...(thas right..now u can brag to ur frnds..that u hacked ur OS...LOL)...
x.y.z is ur current kernel version....
1. make sure you got all kernel sources in place (usually /usr/src/linux-x.y.z)

2. edit /usr/src/linux-x.y.z/kernel/signal.c in ur fav editor
goto the place where u see somethin like this ..shortcut is Use find option of editor & find for EXPORT
EXPORT_SYMBOL(recalc_sigpending);
EXPORT_SYMBOL_GPL(dequeue_signal);
EXPORT_SYMBOL(flush_signals);
EXPORT_SYMBOL(force_sig);
EXPORT_SYMBOL(kill_pg);
EXPORT_SYMBOL(kill_proc);

3. add this line at the end of all those EXPORTs
EXPORT_SYMBOL(kill_proc_info);
save & close out.

4. goto /usr/src/linux-x.y.z & do
$make bzImage
( i am not sure about <make modules modules_install> ,whether u should do it or no....)

5. issue the following still in same dir
cp arch/i386/boot/bzImage /boot/vmlinuz-x.y.z
(/boot/vmlinuz-x.y.z should already be existing unless u r doing a fresh kernel compile..go ahead & overwrite it)

restart & enjoy
possibly u might have to do /usr/share/lufs/prepmod again..but this time it will be clean

Wow, that worked!

Tanx a lot mayhemt, I had almost given up on this, and now you come and fix my problem with a simple line to edit

---
Btw, could you explain me why it worked with that line in that file?
and is captive secure for writing to ntfs without it messing up the partition?

mayhemt · 09-07-2005, 06:30 PM

hehe..i m not that hardcore linux geek....(i do most stuff on mainframes..LOL)
but my idea is this
captive had been in development & support for a while when kernel was in 2.4 stages & in early 2.6 stages... the author Jan finally stopped working on it. Meanwhile Linus & others working on kernels..dropped the dreadful kill_proc_info (which is still needed by lufs modules) from the code post kernel 2.6.6 (or earlier..dont know when it exactly happnd) ...so we hacked kernel to export this variable...dats all

is captive secure? captive is written basically around windows NTFS drivers itself...so it should be pretty safe according to the author of captive. However its slow to write huge files atleast on my linux box. its safer than the kernel's in-built ntfs-write support module.

Tanx for the info, you really helped me out

cowlip · 09-26-2005, 12:09 AM

Hi, instead of editing the kernel, you can do it this way, editing only prepmod:

sudo gedit /usr/share/lufs/2.6/inode.c

Search for:

/* notify the daemon that we're going bye-bye */

and then change "kill_proc_info" to just "kill_proc" and its good.

ogin · 11-25-2005, 06:18 PM

thanks cowlip, it works nicely.

trainpic · 04-01-2006, 08:21 PM

Works for me now too on Ubuntu 5.10

Same problem, same solution
(edit inode.c)
