Constant net activity while running?

Topic 192758
(moderation:
I recently had to replace one of my computers used for E@H. With the newly downloaded BOINC/E@H, I now notice that there is continuous network activity (as indicated in my Zone Alarm icon). The activity stops only when I suspend E@H processing, and has been going on for hours now. All the files were downloaded properly, and my computer is crunching away at the numbers just fine.
I am not an alarmist, but I am very concerned about what is taking place. There is nothing indicated in the "Transfers" columns, nor in the "Messages" columns that indicate a need for my computer to be 'calling home' continuously like this.
(The I/O indicator icon shows this network activity to be evenly cyclic... about a 2-second period, with two pulses of medium-activity input, and a single, low-length outgoing response from my computer.)
Another, unrelated question: I am shown as having five computers online for this project when, in fact, I have only two. How can I 'delete' the obsolete or duplicate computer entries (or do I even have to)?
Thanks for your help.

Zone Alarm is monitoring the internal TCP(?) activity between the BOINC client and apps and I believe that is what is what is what Zone Alarm is registering. I know I've read two or three threads concerning the same "problem". If possible, you may see if you can open some permissions up through ZA so it will quit with the alerts.
Highlight Einstein in the Projects tab of your BOINC Manager and tag the "Your computers" button. Click on each computer ID and in the page that is brought up, look for "merge this computer" toward the bottom of the page.
Thank you for the quick

Thank you for the quick response! :-)
Actually, it isn't an 'alert' that I see at all. It's just the little Zone Alarm icon in my taskbar which shows a small bar-graph of I/O activity. Normally this is quiescent (unless I'm surfing the net of course). But whenever E@H is crunching numbers, it shows continuous network activity, and I didn't think it should be showing *internal* activity between the BOINC client and the E@H application. That shouldn't invoke transmission over the Internet unless I'm actually uploading results or receiving a new file of raw data. I do not see this happening on my other computer, and the Zone Alarm settings (permissions) are identical.
As for my other question, I had always wondered what the "Merge This Computer" function was all about. Thanks for explaining it to me!

Yup, this little bar-graph is misleading. If you open the ZA "Control Center", there's also this bar graph with the caption "Internet" displayed, so it's only reasonable to think this is "Internet" traffic.
But for BOINC / Einstein at home, it's really not. To reassure you, just do the following:
If your PC is connected via LAN: pull out the network cable :-). If connected via WLAN, disable the WLAN card !
You will see that ZA will continue to show this traffic pattern, although obviously nothing is transferred to or from the internet.
(A less dramatic way would be to use the netstat command to inspect the open network connections).

I did just what you suggested. I disconnected the LAN connection and the little graph continued to bounce up and down. It's good to know that all is OK... so I won't continue to worry about it.
Thank you both for your help; I really do appreciate it. :-)

It's not communication
)
It's not communication between boinc client and eintein application, that communication is performed over shared memory segment.
It's communication between boinc client and the controlling graphical manager.
In addition if you find it
)
In addition if you find it annoying, you can run BOINC as a service or from the command line. That way the Manager is not active all the time so you don't have the RPC traffic on the localhost interface, unless you call up the Manager to see what's going on.
It gains you about ~1% more CPU time for crunching as well. ;-)

Say it with me 3 times...
Brian...whose giddy interruptions into valuable threads ("hijacking", I think the mods would call it) is due to the effects of lack of sleep, and lack of motivation to complete my Java work...I have just one thing on one final assignment and then the exam to do, and I've been putting it off... :sigh:
I wish I knew how many points were remaining out, because up to this point, I've gotten 100% on everything... The web portal doesn't show the remainder of the things to be graded and their point value though...

LOL!!
There are 10^11 stars in the galaxy. That used to be a huge number. But it's only a hundred billion. It's less than the national deficit! We used to call them astronomical numbers. Now we should call them economical numbers. - Richard Feynman
Full ack :-D Btw, in Germany,

Full ack :-D Btw, in Germany, there is a story about a (very dumb) guy who wanted to "hack" someone else and got told the IP was 127.0.0.1 and who ended up killing his own computer. Thinking of it still makes me laugh...
I really felt like ordering

I really felt like ordering one, but 38 $ :-/ ??!!!?
YES!!!! A classic!

So funny!
P.S.: There's some slightly ...inappropriate...language in this transcript of the "hacking attempt", btw.
