Hi, 
Good to hear that you use Opensand. 

The main developer of OpenSAND is in vacation for now so you will not get a perfect answer soon. 
I am in vacation this evening : I hope other people from the mailing list will manage to help you.

First, be sure that the IPv4/IPv6 networks you use is not used on another interface and be sure that your interfaces are dedicated to OpenSAND with their own network. Secondly, be sure to use the advanced network configuration at the opensand-daemon package configuration process. 
Try to redo : "dpkg-reconfigure opensand-daemon" and use the advanced network configuration. The automatic one may not work so well on the last version.

I cannot say more to help you. What is strange is that it has worked for 3 machines so it must be something not so difficult.
Besides, you don't need to install OpenSAND on the Workstations. 

Hope it helps ! 

Cordially, 

Emmanuel Dubois

Objet : [Opensand] Cannot initialize OpenSAND interfaces: IPV6 address

Hello Everyone,

We  are currently in the initial stage of configuring Opensand emulation platform on top of a rack of 6 machines running on Ubuntu 12.04 LTS (64bits), which are expected to form a platform of 1 SAT, 1 GW, 2 STs and 2 WSs,  SAT/GW/ST can be detected from the manager on 2 machines, but found the following errors on converting the ipv6 address to GW/ST in the daemon.log on the other 4 machines.

Jul 19 13:02:38 testbed sand-daemon[3158]: address 192.168.18.2/24 already exists on eth0
Jul 19 13:02:38 testbed sand-daemon[3158]: listen on 0.0.0.0:5926
Jul 19 13:02:38 testbed sand-daemon[3158]: address 192.168.20.5/24 already exists on eth1
Jul 19 13:02:38 testbed sand-daemon[3158]: address fe80::21c:23ff:fee2:9b91/64 already exists on eth1
Jul 19 13:02:38 testbed sand-daemon[3158]: cannot initialize OpenSAND interfaces: invalid literal for int() with base 10: '9b91'
Jul 19 13:02:38 testbed sand-daemon[3158]: listen for states on 0.0.0.0:5358
Jul 19 13:02:38 testbed sand-daemon[3158]: Starting the stats handler
Jul 19 13:02:40 testbed sand-daemon[3158]: service thread is not started correctly: quit

GW configuration:

[service]
name = gw
instance = 0
type = _opensand._tcp
interface = 
port = 3141

[command]
port = 5926

[state]
port = 5358

[network]
config_level = advanced
emu_iface = eth0
emu_ipv4 = 192.168.18.2/24
lan_iface = eth1
lan_ipv4 = 192.168.20.5/24
lan_ipv6 = fe80::21c:23ff:fee2:9b91/64


Currently only 2 machines can work with each other and found as SAT/GW/ST from the manager, the other 4 machines give the same error right after configuring the daemon, does anyone encountered similar problem? Is it a ipv6 issue or some others relating to string conversion or wrong configuration? I can hardly see there is any problem of converting fe80::21c:23ff:fee2:9b91 to int, All machines are freshly installed with same settings, and connected via a switch.


Any comments would be more than helpful. Thanks! 


Best regards,


Hongfei
