When this happened, my daily email alert started reporting that it couldn't find any of the rpm repositories, from which I deduced that lon-capa uses ping to determine whether or not those hosts are up. I requested that IT open up ping from our lon-capa server, and they apparently did so. The script now finds distro.ibiblio.org, but cannot seem to find the install.lon-capa.org, or mirror.pa.msu.edu. Several questions: (1) do other people see problems with install.lon-capa.org and mirror.pa.msu.edu? (2) If not, what other services does lon-capa use that might cause failure at the msu sites, but success in connecting to distro.ibiblio.org? (3) Somewhat related: Our IT staff will soon be introducing a campus-wide firewall that is supposed to allow all outgoing connections initiated from inside campus, but block all incoming connections unless we explicitly request holes. According to the lon-capa FAQ, the following ports and services are required to be open: Port 5663, for the TCP/IP course management traffic layer Port 80, for HTTP Port 8080, for login This may be a naive question, but what *services* are used on port 8080 for login? Just http? ssl? Are there other services than the TCP/IP layer on port 5663, or are all those services nicely wrapped? I am pretty sure we need to provide not only port information, but a complete list of services offered on each port. Thanks for you help.

Just my $0.02: If you want to continue doing this, why not probe whether the ftp service is available. That's what you care about, not ping responses (SFU is blocking pings as well and after the latest onslaught of worms you'll have a hard time to convince sysadmins to reenable those).

Maybe you have yourself in > the Admin list twice? I am getting two emails for each server as well. My suspicion is that this is a bug in CHECKRPMS (not check-rpms :-): it sends email to lonAdmEMail (see the line my $emailto = "$perlvar{'lonAdmEMail'}";) without checking whether the MAILTO variable is set in /etc/crontab. Since cron sends email to whoever is specified in the MAILTO variable, CHECKRPMS happily sends mail to lonAdmEMail as well. If your email address appears in the MAILTO line (as it should if you are a responsible sysadmin :-), and your email also appears in lonAdmEMail, then (that's at least my suspicion) you get two emails.

However, Hon-Kie was right: I also found a loncapa.lpmlsave in /etc/cron.d (a really stupid place to put a *.lpmlsave file, isn't it?). Hence there is a good probability that that's the reason. Will find out when the cron job runs next time. You won't find the loncapa.lpmlsave file anymore - I removed it.

Is it deliberate? It seems to me that in both cases we use metasend, in the case of the from clean restart, the amount of info to send is larger (due to more errors being generated because nothing is running etc) and thus metasend tries to be 'intelligent' and not send one huge email. If you want to defeat this edit /home/httpd/perl/loncron You'll see at the bottom system("metasend -b -t $emailto -s '$subj' -f $statusdir/index.html -m text/html"); Change this to system("metasend -S 4000000 -b -t $emailto -s '$subj' -f $statusdir/index.html -m text/html"); > And while I'm on the subject, any ideas why I get errors reported when I > do the restart by hand, but the cron job doesn't report any? The fact that lonc, lond, lonhttpd, and lonsql aren't running is considered an error. Perhaps it should be a bit smarter and recognize that in this case it would be an error if they were running. But it seems like a lot of work for not a lot of gain. . . -- guy at albertelli.com LON-CAPA Developer 0-7-5-7- From guy at albertelli.com Thu Sep 18 15:43:01 2003 From: guy at albertelli.com (Guy Albertelli II) Date: Thu, 18 Sep 2003 15:43:01 -0400 (EDT) Subject: [LON-CAPA-admin] Two copies of LON status/rpm upgrade reports In-Reply-To: <20030918190814.GB22412@stikine.ucs.sfu.ca> Message-ID: <200309181943.h8IJh1eT017548@mileva.lite.msu.edu> Hi Martin, > I am tempted to reverse my opinion on CHECKRPMS (or maybe not, don't know > yet).

If you have accessed the resource in the past you already have a copy of it on your machine and you will be fully able to see and/or answer any resources on the machine immaterial of the current status of the connection to MSU. You only need the connection to MSU if you are trying to see a resource for the first time.

The really funny thing is that the pdf file, complete with figure, is generated just fine. We had some issues with gnuplot on our first install. I don't know if you use gnuplot for the random labels or not, but if so, that may be a first clue. I get the same behaviour with other random label problems: http://loncapa.mines.edu/priv/csmphyslib/type55_potential/EquipotentialLines.problem I noticed that I also get the "meta file not found" error, but not the seg-faulted processes with these problems, even though they are not random label problems, and one of them contains no graph at all. http://loncapa.mines.edu/priv/csmphyslib/type55_potential/RadialElectField.problem http://loncapa.mines.edu/priv/csmphyslib/type55_potential/SymmetricCross.problem http://loncapa.mines.edu/priv/csmphyslib/type55_potential/SphericalInsulatingShell.problem I have included all of the above problems in a course called "Test Course". When I access the problems as either course coordinator or student, I no longer seem to get the "meta file not found" error, but I still get the 10 lines of seg fault in the error_log file, for the random-label problems. Occasionally, the gif will show up properly the first time it is viewed, but upon a reload, it disappears. Students can still print the proper image just fine. I have added albertel:msu to the course as both student and instructor if that will help. Thanks for you help. We seem to be giving you a fair number of challenges.

In a particular chapter there are 19 possible points. However, when students check their grades, it lists their score as 16/16. I can verify that they successfully answered the three questions that are being excluded from the chapter score. In addition, as Teaching Assistant their score is listed as 16/19. Two of the questions are essay response, the other is numerical response. These questions were authored by students here at NDSU. So, my questions are: 1) Could this be behavior due to bad authoring? 2) If not, how can I correct this. As I said, if we look at the student's response, it clearly shows that they've been given 1/1 for the essay question and for the numerical response there is a check mark indicating that LON-CAPA graded it as being correct.
