Wonderful. As soon as I saw your message this morning, I logged onto brisa and made the modifications. You are now up and running LDM-6.0.10 and reporting real time statistics. To take a look at the real time statistics, you can look at: http://www.unidata.ucar.edu/staff/chiz/rtstats Click on the 'Statistics by Host' link and then on the 'brisa.meteoro.ufrj.br [ 6.0.10 ]' link. In the second page, you will find entries for each type of data feed you are receiving. The real time statistics have demonstrated that there is a problem with the clock on your system: it is over an hour in the future. I verified this by logging on to brisa and running 'date -u' while simultaneously doing the same thing on a machine here in our office: brisa.meteoro.ufrj.br: address@hidden ldm]$ date -u Tue Apr 22 00:34:51 UTC 2003 thelma.ucar.edu: /local/ldm% date -u Mon Apr 21 23:33:42 GMT 2003 Would it be possible for you to reset the clock on brisa? I found that running ntpdate from 'root's cron once-per-hour is usually sufficient for keeping a system's clock set correctly. I know that RPN operates at least one time server for each state in Brazil: http://www.rnp.br/lang/cais_en/ntp/ so you do best to use the one in Rio: ntp.pop-rj.rnp.br (18.104.22.168) As per the RNP web page, you should send an email to notify them that you are using this time server: location: PoP-RJ/Brazilian Research Network (RNP) synchronization: NTP V4 Secondary (stratum 2), IBM-RS6000/AIX service area: Brazil access policy: Open access to stratum 2 and stratum 3 NTP servers. Please, send an e-mail to notify. contact: address@hidden The ntpdate invocation I would setup if I had 'root' access on brisa is: 0 * * * * /usr/sbin/ntpdate ntp.pop-rj.rnp.br > /dev/null >Glad to help. I really appreciate your help in getting this setup and working properly! Cheers, Tom Yoksas >From address@hidden Mon Apr 21 19:45:39 2003 Tom, The clock skew was due some strange bug on ntpd service running on brisa when it was last restarted (April the 16th). I had solved the issue like you said, back when you did first ldm setup, only pointing to a local ntp server (ntp.ufrj.br) instead of the one you mentioned. The clock is adjusted now. Let me know if anything else is needed. Best Regards, David Garrana
