Hi, I've installed NTP daemon on my firewall (with sync to external machine) and on all internal machines (with sync to my firewall).
I found that this had opend port 123/udp on my firewall, so now everybody from the net can use my machine as a server. I have nothing against this as long as this is secure. Is it ? If not can I limit allowed clients somehow ? (I noticed that DENY on ipchains to others than my reference external server limits ntptrace usage).
