The ldmping failure you sent previously would work even if atm does not have an allow for your machine. Since the LDM on atm _is_ running (it is feeding a LOT of downstream sties), and since an ldmping from your machine failed, I am beginning to suspect a firewall issue on your side. re: fully qualified hostname of your LDM machine unidata.scs.gmu.edu Thanks. re: forward and reverse name lookup for your LDM machine >Hmm, I don't think so. This _will_ be a problem. One of the requirements is that a downstream machine have forward and reverse name lookup. This relates to security on the server side. I just checked, and your machine does not have both forward and reverse name lookup: % nslookup unidata.scs.gmu.edu Server: 126.96.36.199 Address: 188.8.131.52#53 Non-authoritative answer: Name: unidata.scs.gmu.edu Address: 184.108.40.206 % nslookup 220.127.116.11 Server: 18.104.22.168 Address: 22.214.171.124#53 ** server can't find 126.96.36.199.in-addr.arpa: SERVFAIL You need to contact your network folks and work with them to get forward and reverrse name lookup for your box. re: what does your ~ldm/logs/ldmd.log file have to say >I have ~ldm/logs/ldmd.log, but it is always 0 byte -- it's empty. the file >owner is ldm, and group is unidata (which include gempak, mcidas, and ldm) This tells me that it is very likely that your /etc/syslog.conf file has not been setup/setup correctly for the entries needed for logging. Please check this file for the following: 1) entry for local0.none. It should look like: *.info;mail.none;news.none;authpriv.none;cron.none;local0.none /var/log/messages ... # Unidata LDM local0.debug /usr/local/ldm/logs/ldmd.log NOTE: white space between the service and the log file pathname are tabs, not spaces! This is important!! >Yeah, when we first contacted with unidata support, we were told our >"unidata.scs.gmu.edu" should point its request to "atm.geo.nsf.gov". This is correct. I meant to say that I am seeing NO denial messages in the ~ldm/logs/ldmd.log files on atm. This means that your feed reqest is not making it to atm. This, in turn, tells me that there may be a firewall issue on your end. The things to look for now are: 1) firewall rules on your machine or in your department/domain that would keep unidata.scs.gmu.edu from making requests to atm.geo.nsf.gov on port 388 2) work with your network folks on getting forward and reverse name lookup setup for unidata.scs.gmu.edu 3) one last thing I forgot to ask: did you make sure to run the final installation step as 'root': cd ~ldm/ldm-6.0.14/src ./configure make make install sudo make install_setuids <- this is the step I am talking about -- or -- <as root> cd ~ldm/ldm-6.0.14/src make install_setuids <- this is the step I am talking about >Thank you!
