  NTP on OpenVMS using TCPIP services         


Author:
Date: Jul 4, 2008 05:22

Spooky! As AEF's query comes in, I seek clarification on what I'm seeing...

Versions FWIW VMS 7.3-1, TCPIP 5.3 eco 2, also OpenVMS 8.3 (Alpha) and
TCPIP 5.6, time server Windows Server 2003, and Windows XP professional.
NTP version on VMS is 4.1

NTP on this Alpha was working quite well with a UNIX NTP server, until
it was retired.

Scenario is, using the documentation for HP's TCPIP services I set up
NTP naming two Windows servers as "peers". Debugging this using
TCPIP$NTPQ shows a REJECT status in the "associations" display.
Increasing the log level using the logical TCPIP$NTP_LOG_LEVEL (to 3)
just seemed to indicate nothing was happening to correct the time.

So I replicated the scenario at home, and used my XP Pro system as a
server, and set up the same way got exactly the same symptoms. I enabled
detailed logging on the Windows side (microsoft technet articles) and
saw the requests coming in, and even the correct value / difference in
time was reported and the stratum was 0. What I had proved was that it
wasn't a firewall or authentication issue. I was now in a position to
start looking at the NTP CONF file.

This week has seen several personal independence days for me -- the 1st of
July and the 3rd of July. Today, it's Independence Day for all Americans.
I hope you'll be celebrating Independence Day today with the same vigor as
I.

  VMS SAN Primer         


Author: Paul Lentz
Date: Jul 4, 2008 00:08

I'm looking at trying to get a System Admin Job. I've worked with VAXen for about 13 years with some of that as a Admin in a static
but scaling-down shop. I also worked with Alphas.

I keep having to hem and hah when it comes to questions about SAN, and I guess it's config :-). I had to do (re)configuration on
Storage Works boxes and HS series controllers. But never got to touch anything officially labeled SAN. I've done a few quick
searches to try and find a primer on what is usally excellent VMS documentation available on the web, but haven't really found
anything definitative.

Can anybody point me in the direction to get started to become a VMS Alpha SAN know-it-all???

Thanks!
*Paul*
