Hello Julien.
 Thank you for your quick response.

 Your first advice, about using "sudo opensand_tun; sudo sand-daemon -f"
really helped me a lot. I found that there was a problem with the
daemon.conf file, where I should have added an lan_ipv6 address as well.
Now I'm able to start deamon but lots of warnings arise. Also using
ifconfig I dont see an opensand interface, just eth0, eth1 and lo.

/output of sand-daemon -f:
2012-12-14 13:56:01,691 - sand-daemon - WARNING - IPv4 forwarding on
interface opensand is disabled, you won't be able to route packets toward
WS behind this host [sand-daemon:215]

 You were completely right about the second issue as well.
 I have missed the part where I should copy the plugin scripts in manager's
modules directory. As soon as I copied the files, the manager passed this
step. Unfortunately, now crashes when loading the topology file. Below is
the output:

/2012-12-14 14:02:16,418 - sand-manager - ERROR - failed to initialize
OpenSAND Manager: need more than 1 value to unpack
Traceback (most recent call last):
  File "/usr/bin/sand-manager", line 110, in __init__
    self._model = Model(self._manager_log, options.scenario)
  File

line 96, in __init__

line 177, in load_topology
    except IOError, (_, strerror):

 Finally, Im running 32bit ubuntu release and I would be more than happy to
install openSAND from debs, but I need to use the v.1.0.0 because of this
bug (https://bugs.launchpad.net/opensand/+bug/1015156) and the loss model
plugin.

 Thank you a lot for your help.

 Yannis

 P.S. I noticed that this bug
https://bugs.launchpad.net/opensand/+bug/1015156 status has changed to "Fix
Released" in milestone 0.9.0. This means that deb installation 0.9.0
includes the patch?
