Re: Unix domain socket

Hi Dave,

Could u please let me know in which version this patch was eventually included?
Currently we still use our own modified driver (based on the 08.00.0004) and we
would like to upgrade.
Our best option would be to use a standard RedHat RPM (4.0/5.0 AS famiy).
Otherwise, we would use the latest from your site.
Thanks,
Ramon
