Re: [Leaf-user] rdate, udp and Bering
You'll have to open up TCP 37 from your firewall to the net in order to use rdate. -Tom - Original Message - From: Stephen Lee [EMAIL PROTECTED] To: Leaf-user [EMAIL PROTECTED] Sent: Thursday, March 28, 2002 1:05 PM Subject: [Leaf-user] rdate, udp and Bering On Thu, 2002-03-28 at 12:56, Michael D.

All we have open are: ntp 123/udpNetwork Time Protocol Adding port 37 to FW_TCP_OUT_PORTS in Bering got rdate working. Adding port 123 (either udp or tcp) did not work for me. Thanks for the help!

Could there be some firewall setting causing this problem? as Tom allready stated it is. rdate uses port 37 and this is denied by default change shorewall settings 1 ) params FW_TCP_OUT_PORTS=53,37 and restart shorewall (don't forget to backup ) I do not know which `rdate' is in Bering. Dachstein, c. uses busybox rdate. Bering uses also Busybox v0.60.2 rdate Regarding firewalled ports, have you checked these? ntp 123/tcpNetwork Time Protocol ntp 123/udpNetwork Time Protocol With me rdate ntp0.cornell.edu functions after the modification i indicated above. The connection refused comes from your own router not from the timeserver. PS you are talking about using rdate from the router not from a linux machine in the internal network ? The parameter I talked about before is firewall --- timeserver. otherwise the firewall should not be blocking.

[Leaf-user] rdate, udp and Bering
Hi, I noticed that rdate from Bering does not seem to accept the -u switch for time requests using UDP. I suspect many of the RFC868 rdate servers are only accepting UDP requests because under RedHat7.2 I needed the -u switch to get a response for most of the servers tried.
