HAL Daemon problem

I'm getting the boot process stuck by the hal daemon.  My daemons line in rc.conf is:

DAEMONS=( syslog-ng network netfs @adsl crond acpid alsa hal )

After loading DBUS, the boot process stops loading hal.

If I try to load hal manually with:

/etc/rc.d/hald start

it fails.

Anyone with this problem? HAL worked but I can't get it to work now.

Thank you very much.

Re: HAL Daemon problem

What message do you get when you try to start hal? If it is something about missing a shared dbus library, then there was likely a problem with the dbus update when you last updated it.

Try closing all X sessions and, from the console force dbus to re-update by running: pacman -Sf dbus

I had this problem on all my machines running arch - we should both check the package news more often!

Re: HAL Daemon problem

I don't remember if dbus and hal were updated during my last pacman -Syu.

Let's see /var/log/pacman.log:

[2008-04-07 23:54] upgraded dbus (1.0.2-4 -> 1.1.20-2)

HA!

This is the message when I start hal (and it's related to dbus, of course):

# hald --daemon=no --verbose=yes
11:33:17.864 [i] hald.c:634: hal 0.5.10
11:33:17.865 [i] hald.c:699: Will not daemonize

11:33:17.865 [E] hald_dbus.c:5578: dbus_bus_get(): Failed to connect to socket /var/run/dbus/system_bus_socket: No such file or directory

Seems dbus is not running, try again with dbus running:

[root@itchies log]# /etc/rc.d/dbus start
:: Starting D-BUS system messagebus                                      [DONE]

[root@itchies log]#

Seems that hal cannot communicate with the running instance of dbus (or dbus is not replying the hal requests).

Well, anyway I'm closing X now and trying your solution.

I'm back in a few seconds to tell results hehe.

thank you very much.

Re: HAL Daemon problem

It keeps failing to communicate with dbus.

I will try to recompile hal maybe linking with the new dbus shared library fixes it.

Re: HAL Daemon problem

I remember now that I've unpacked some data.tar.gz from a .deb in the root directory.

Maybe this changed some pemissions?

I've found e.g /usr to have hernan:1000 (my user,group) instead of root:root.

1) How I can check the permissions of the / directory?

2) What are the default permissions for (.) and (..) in each directory?

I got e.g:

[hernan@itchies ~]$ ls / -al
total 77
drwx------ 20 hernan root  4096 2008-04-08 17:24 .
drwx------ 20 hernan root  4096 2008-04-08 17:24 ..
drwxr-xr-x  2 root   root  4096 2008-03-30 20:51 bin
drwxr-xr-x  4 root   root  1024 2008-03-30 20:52 boot
drwxr-xr-x 18 root   root     0 2008-04-08 17:47 dev
drwxr-xr-x 43 root   root  4096 2008-04-08 17:41 etc
drwxr-xr-x  6 root   root  4096 2008-03-29 03:49 home
drwxr-xr-x  6 root   root  4096 2008-03-30 20:37 lib
drwx------  2 root   root 16384 2008-03-28 19:38 lost+found
drwxr-xr-x  5 root   root  4096 2008-03-29 03:49 media
drwxr-xr-x  8 root   root  4096 2008-04-06 10:51 mnt
drwxr-xr-x  5 root   root  4096 2008-03-30 20:37 opt
dr-xr-xr-x 94 root   root     0 2008-04-08 14:40 proc
drwxr-x---  7 root   root  4096 2008-04-08 03:18 root

drwxr-xr-x 12 root   root     0 2008-04-08 14:40 sys
drwxrwxrwt  6 root   root  4096 2008-04-08 17:47 tmp
drwxr-xr-x 11 root   root  4096 2008-03-24 09:49 usr
drwxr-xr-x 13 root   root  4096 2008-03-29 04:36 var
[hernan@itchies ~]$

At /usr

[hernan@itchies usr]$ ls -al
total 152
drwxr-xr-x  11 root   root  4096 2008-03-24 09:49 .
drwx------  20 hernan root  4096 2008-04-08 17:24 ..
drwxr-xr-x   3 root   root 36864 2008-04-08 11:50 bin
drwxr-xr-x 155 root   root 20480 2008-04-08 11:50 include
drwxr-xr-x  66 root   root 61440 2008-04-08 11:50 lib
drwxr-xr-x  10 root   root  4096 2008-03-10 20:20 local
drwxr-xr-x  26 root   root  4096 2008-04-04 23:42 man
drwxr-xr-x   2 root   root  4096 2008-04-08 11:50 sbin
drwxr-xr-x  86 root   root  4096 2008-03-24 09:49 share
drwxr-xr-x   3 root   root  4096 2008-03-30 06:48 src
drwxr-xr-x   3 root   root  4096 2008-02-13 08:18 usr
lrwxrwxrwx   1 root   root     6 2008-03-10 20:20 var -> ../var
[hernan@itchies usr]$

maybe this is the source of all my problems (e.g I can't sudo even from root, I get 'permission denied to /etc/sudoers').

Thank you very much.

Re: HAL Daemon problem

chmod 755 /

sudo and hal NOW WORKS!!!!

Well seems that uncompressing a .tar on / is not a good idea.
