I am currently seeing dozens of downloads like the following while the CPU is nearly idle:

They seem to belong to a merge job.
Shouldn´t those jobs kept inside the CERN network?

Message 28776 - Posted: 3 Feb 2017, 12:52:15 UTC - in response to Message 28775.  

After the download of more than 500 files the job got stuck.
I noticed that the VM requested access to TCP port 1094.
This was previously not documented.

Any comments from the developers?

Yes, those are certainly unmerged jobs in the downloads, and no, they shouldn't be getting out. I'll make sure the crew is aware.

[Edit] Oh, hang on, those are log files! What's going on here? [/Edit]

Port 1094 is for rootd access, directly accessing remote files from ROOT programmes (and others). It's used in CMSSW to access data (.root) files stored on remote systems.
This is all very strange.

My VMs produce .root URLs as output of every job.
Normally they upload completely although TCP port 1094 is closed - except the highlighted one below.
That one would have been an error 151 some weeks before (you already explained that).

I would like to close TCP port 1094 if it is not necessary for normal tasks.

As far as I'm aware, we don't use (x)rootd to write files, we stage-out with gfal-cp. rootd is usually used to read files which are to be further processed, it's the mechanism by which we can access our data files on remotes systems, and by using xrootd "redirectors" we don't even need to know where they are.

I would like to close TCP port 1094 if it is not necessary for normal tasks.

As your examples show, the gfal/davs protocols use HTTP (I believe over port 80) so I can't think of a reason for 1094 to be open.

Ah! I've just found out that as well as Merge jobs there are also LogCollect jobs. I'll ask Laurence to try to identify them so they can be kept within CERN as well.

OK, Laurence has just told me that LogCollect jobs are now being excluded from Volunteer machines as well as Merge jobs. From a scan of the Condor queue on Friday afternoon, I believe these are the only two categories of CMS_JobType apart from Production (which is the category Volunteers can process). If anyone spots another category, please let me know!
