NTP - stratum 2 server connection refused

[Allan Pincus]

Hi,

I'm trying to sync my server to a stratum 2 server.

I went to ntp.org and got IP addresses for a number of them. I am able to ping the servers, so that's good news.

When I try to connect my server to one of them, I get the message:

29 Aug 12:37:14 ntpdate[15444]: can't find host timeserver
29 Aug 12:37:14 ntpdate[15444]: no servers can be used, exiting


In the notes on the page, there was something about upgrading to NTP version 4. I looked through some HP-UX 10.2 patches, but did not find anything that looked quite right.

A couple of questions:

1. Does anyone know why I'm getting this error?

2. Does anyone know which patch bundle to download to go to Version 4?

Allen,

I think you need PHNE_23717 "s700_800 10.X NTP timeservices upgrade plus utilities". And an upgrade to 11.x.

I can't upgrade right now to 11.x until a vendor of a major software package moves to 11.x and confirms this is not an issue.

Any additional thoughts? I'll download the patch.

On further review, that will only upgrade NTP to v3.5. I suspect there probably is no v4 of NTP for 10.20.

May be this patch - PHNE_23717 will help you.

Actually, Allan, I'm not sure there is a Version 4 available at all for HP-UX. The man page for xntpd on my 11.11 systems still refers only to version 1, 2, or 3. The patch database only shows v3.5, even for 11i. And my searches of hp.com aren't coming up with one. You should be able to go with a version 3 server, though.

oops .. I didn't know it was already mentioned.

Did you check the netdaemons file and see if your server name is added there? Did you have entries in the ntp.conf file? Could you do the nslookup on the server?

Check this setup document and review your settings and make sure that you haven't done anything wrong:

Hi. Is it impossible for you to build the 4.1.1 version of ntp from source? The only reason I can see for this causing trouble would be the lack of gnu tools on your system: gmake, gcc, etc., all of which could be installed, from source, reletively easily. If you have some trouble building ntp from source, I found a URL with some hints for building it on HP-UX:
