NTP doesn't connect to you, so you shouldn't need any special firewall rule. Your system goes out and connects to the NTP server, and if you make this system a server also, then all the internal systems should connect to it, to set their time. The internal network should be open to all systems, so all the clients should be able to get the time. -----Original Message----- From: plug-discuss-bounces@lists.plug.phoenix.az.us [mailto:plug-discuss-bounces@lists.plug.phoenix.az.us] On Behalf Of Steven A.

Hmm, so I did the following: # iptables -A input_ext -p tcp -m tcp --dport 123 -j ACCEPT and then tried starting ntp services again but it still seems to hang when trying to get the initial date and time. So adding a rule to the firewall for tcp access on port 123 seems to have made no difference to my problem. nuts... -- Steve -----Original Message----- >From: "kitepilot@kitepilot.com" >Sent: Aug 25, 2009 2:13 PM >To: "Steven A.
