Comment 2 for bug 1549467

Thanks for the info!
I had fully updated clients and server with standard Ubuntu repository.
I updated server and clients to the stable ppa, according to your instructions, but it didn't solve the problrm the output is the same as before:
admin@ts:~$ epoptes
Got clients: 172.22.8.6:50834, 172.22.8.6:50835, 172.22.8.6:50836

**addClient's been called for 172.22.8.6:50836
Can't extract client information, won't add this client

I suppose an instance of epoptes-client is launched for each network interface. As our 172.22.8.6 workstation is also a router, there are several network interfaces.

NOTE (on another client):
I struggled to start epoptes-client, it just hanged showing:
 * Epoptes-client connecting to server:789...
The reason of that was installed and removed epoptes package. I had to remove epoptes completely. So when I ran:
apt-get install epoptes
apt-get purge epoptes
Client start to work again!
