RE: Missed something while using cryptsetup



Well seen !
But , have a look : 

host:/home/user# losetup --encryption aes --keybits 4096 -f /dev/loop2
Password:  *****
Segmentation fault

host:/home/user# losetup --encryption aes -f /dev/loop2
Password: *****
ioctl: LOOP_SET_FD: Invalid Argument

host:/home/user # losetup -f /dev/loop2
ioctl: LOOP_SET_FD: Invalid Argument

host:/home/user # losetup -f /dev/loop3
ioctl: LOOP_SET_FD: Invalid Argument

What's going on ? :'(
Any idea ? :-((((

Thanks :)

Hi,

You probably didn't miss this, but your mail doesn't mention it, so I'll
ask.  Did you set up the loop device to refer to a file before you tried
to do cryptsetup ?  

After all, if you haven't done "losetup" yet, /dev/loop0 will not be a
block device, it will be nothing.
