Credential problem with HAL and USB disk.
#1
Hello there

My USB drives are mounted correctly under xbmc. I can see them and browse & play content.

Xbmc is running as xbmc user ( non root ).
And here is my problem. External drives are mounted read only for the xbmc users. I can see the disk is mounted as root:root in /media.

I'd like those disk to be writable for xbmc user, if I want to use the File Manager of xbmc to copy & paste media from xbmc to the external drive.

I'm completly messed with HAL, tryed many things without success.

My Policykit.conf have this:

<config version="0.1">
<define_admin_auth user="xbmc"/>
</config>


Here is the xbmc log part when usb disk is mounted:

xbmc svn 25851 , 32 bits, debian testing.

Some lightened spirits with HAL here ?

Thanks Smile

Try this as /etc/PolicyKit/PolicyKit.conf
Code:
<config version="0.1">

<match action="org.freedesktop.hal.storage.mount-removable">
    <return result="yes"/>
</match>

<match action="org.freedesktop.hal.storage.mount-fixed">
    <return result="yes"/>
</match>

</config>

I'm going to assume this was in Live RC1. The problem should be resolved in the next live release.

My mistake, it didn't solved it.

I was logued in root while testing... Still can't write on it from xbmc user.

I'm not on live, but Debian Squeeze here.

It's mounted as root:root user, with drwxrwxr-x permissions.

16 drwxrwxr-x 4 root root 16384 déc. 22 09:16 BOOTUSB

cat /proc/mounts | grep vfat gives:
Quote:/dev/sdd1 /media/BOOTUSB vfat rw,nosuid,nodev,relatime,fmask=0002,dmask=0002,allow_utime=0020,codepage=cp437,iocharset=utf8 0 0

Perhaps by changing the 0002 dmask of halevt-mount ? What should be optimal for RW to all users ?

Ok found the trick.

In /etc/halevt/halevt.xml

replacing umask here ( -m 022 by 0 ):

Code:
<halevt:Insertion exec="halevt-mount -u $hal.udi$ -m 0"/>

I've removed -o sync too, to solve slow transfer usb speed on usb key.
