My host used to record properly, now the OS is >listed as 'unknown' and no uptime reports show up :( Netcraft looks at the actual TCP packets sent by the Operating System. If you have RFC 1323 extensions on, it should detect your uptime. tcp_extensions="YES" # Set to NO to turn off RFC1323 extensions. I don't know why they can't detect your OS, however. What version of FreeBSD are you running, and do you have a firewall or other device that might somehow mask the results? >Thanks ... -- Christopher Schulte http://www.schulte.org/ Do not un-munge my @nospam.schulte.org email address.
