Hi,
I've disable ipv6 on an Ubuntu Lucid box as you can see :
cyril@Atila:~$ cat /proc/sys/net/ipv6/conf/all/disable_ipv6
1
cyril@Atila:~$ ifconfig eth0
eth0 Link encap:Ethernet HWaddr 08:00:27:5e:bc:06
inet adr:xx.xx.xx.xx Bcast:xx.xx.xx.255 Masque:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
Packets reçus:2008123 erreurs:0 :0 overruns:0 frame:0

Octets reçus:316289442 (316.2 MB) Octets transmis:150811541 (150.8 MB)
However openvpn seems to be confused sometimes but not always as you can see
with 2 different sessions on the same machines :

So on the same machine, with 2 differents sessions, one time it sees that ipv6
is enabled (tt->ipv6=1) and not the other time (the good one for me !)
any idea ?
thanks
