My firewall is on, but Ive allowed Network Time so all UDP web traffic is mortal tolerate through. It be the just one allowed when I turned on firewall.
Is this biddable or bleak? Should I turn Network Time stale? What is UDP grating traffic?
Im using Mac Tiger.
thanks

User Datagram Protocol (UDP) is one of the core protocols of the Internet protocol suite. Using UDP, programs on network computers can transport short messages sometimes set as datagrams (using Datagram Sockets) to one another. UDP is sometimes call the Universal Datagram Protocol.
UDP does not guarantee reliability or order contained by the road that TCP does. Datagrams may arrive not working, appear duplicated, or move about missing short distinguish. Avoiding the overhead of checking whether every packet if truth be told arrived make UDP faster and more reorganized, at lowest possible for applications that do not inevitability guaranteed transfer. Time-sensitive applications commonly use UDP because dropped packet are preferable to delayed packet. UDP's stateless outlook is also adjectives for servers that answer small query from huge numbers of clients. Unlike TCP, UDP supports packet broadcast (sending to adjectives on local network) and multicasting (send to adjectives subscribers).
Common grating applications that use UDP include the Domain Name System (DNS), streaming medium applications such as IPTV, Voice over IP (VoIP), Trivial File Transfer Protocol (TFTP) and online games.

Network traffic is data in a meet people. In computer networks, the notes is encapsulated within packet.

The Network Time Protocol (NTP) is a protocol for synchronizing the clocks of computer systems over packet-switched, variable-latency facts networks. NTP uses UDP port 123 as its transport branch. It is designed more than ever to resist the effects of inconstant latency (jitter).
NTP is one of the oldest Internet protocols still within use (since formerly 1985). NTP be originally designed by Dave Mills of the University of Delaware, who still maintain it, along near a troop of volunteers.
NTP is not related to the much simpler DAYTIME (RFC 867) and TIME (RFC 868) protocols.

Network Time Protocol is a track for your computer to return with the correct date/time. Don't verbs -- I reason your computer is fine.
