Hello list

i have a problem using openvpn on a BUC 4.3.3 installed on a PC Engines 
ALIX (cpu geode); here some messages from daemon.log when I try to 
establish my openvpn connection:

My openvpn server is a OpenSuSE 11.2 with openvpn 2.1.0 and openssl 
0.9.8; the same machine is an openvpn server for many Windows clients an 
a BUC 3.1 client with no problems (it is in production since early 2009)

I have tried to search on google about the TSL BIO error and it seems to 
be an openssl bug: give a look here
https://bugzilla.redhat.com/show_bug.cgi?format=multiple&id=538456
https://bugzilla.redhat.com/show_bug.cgi?id=537962

Someone have some suggestions? Or I must install an old BUC version?
Upgrading the OpenSUSE 11.2 vpn concentrator is not an option :-( !

thanks
Ciao
