Under ubuntu 10.04 Linux 32 bit the advantage driver (10.1) works fine
and the is listed in the phpinfo()
No connection problems, everything is fine.

On ubuntu 10.04 Linux 64 bit I use the same database configuration,
network and dns are well configured but
the advantage driver does not work althoug it's listed in the phpinfo().

Errors: Connection time out an sometimes Error 6097
