If we can't even get or send work units, it doesn't bode well for contact with any alien civilisation ! lol


I'm more worried that the indoor temperature in my house is dropping due to lack of work units... And cold wind from Russia will reach us (where I live) within a few days.

BTW, how can one see that there is a problem?

I know about the http://setiathome.berkeley.edu/sah_status.html page, but that does not tell me if there is a problem with downloading data.

Hello SETI's.

Is there a problem with downloading new data from SETI? One of my linux servers with 8 core CPU is bored at the moment, while the other servers still have work.

The Boinc Tasks, which I run on a windows 7 PC, have a lot of 
"Downloading pending (Project backoff: nn:nn:nn)"
"Downloading pending (Retry in: nn:nn:nn), retried: nn"


Since I always download work for as many days as possible, it must have been a while since the server that does not have any jobs right now, got the last data from SETI.

Thanks for the reply.

I'm not sure what to get out of the thread you asked me to read, but I have a suspicion that I'm not able to use the GPU on my installation... but maybe in the future?

BTW, "Your computers" on seti says:

AuthenticAMD

(8 processors) 	NVIDIA GeForce GTX 750 Ti (2047MB) OpenCL: 1.2


So it seems to be aware of the GPU.

Hello,

Just installed a new Fedora Server 23 with a GEFORCE GTX 750Ti for use with BOINC. But it does not seem like boinc will use it.

All instructions I have found tell me to install "xorg-x11-drv-nvidia-libs" and "xorg-x11-drv-nvidia-libs.i686", but when trying to do a dnf on this, they are not available:

# dnf install xorg-x11-drv-nvidia-libs xorg-x11-drv-nvidia-libs.i686
Last metadata expiration check performed 0:18:36 ago on Sun Mar  6 15:05:37 2016.
No package xorg-x11-drv-nvidia-libs available.
No package xorg-x11-drv-nvidia-libs.i686 available.
Error: Unable to find a match.


Any suggestions how to make this card usable for boinc?
11) Questions and Answers : Unix/Linux : Can't get new tasks (Message 1610502)

Thanks for the explanation of what a feeder is.

One machine hasn't got one single task since seti begin releasing tasks a few days ago, while the other is reaching the limit for the number of tasks they can get (just got the message "This computer has reached a limit on tasks in progress).

So while all the other machines are working like hell, this particular machine is bored.

So that is why I wondered if the message "Info: Expire cleared" has any meaning and can tell why it does not get any work.

BTW, all machines are running Fedora Core (misc versions).

Post:
Not sure what a "feeder" is, but I assume that it's the server side with my client is asking for tasks from, right?

My question is: why do all the other machines I got get a lot of tasks?

I got two 8-core PC's (one running Fedora Core and one running windows 7 and equipped with two GPUs), and a lot of other PC's/servers.

BTW, I tried to install a newer version of BOINC, but I was not able to run it due to missing or incorrect version of run-time libraries. Are there any staticly linked images for Linux that is available? Getting BOINC to run under linux seem to be a problem several people have.

It seems like some of the servers has got new IP's and the firewall stop outgoing traffic to one of them.

Is there any list of which IP's or network addresses that the seti servers have?

Post:
After SETI was available again (after the site move), one of my machine is not able to get any new work. It says "Too many backoffs - fetching master file" and then it goes into hibernate state (Deferred communication for 12-14 days).

I have written a bash script that ask the boinc clinet to do a update every 3rd minute, but after 2 days it has not been able to get anything.

Any reason for this?

About the icmp problem. It was a firewall installed on the new linux host. I disabled it, but that did not help. The only visible change in BoincView was that the ?-mark on the pc icon in the "Locations" list changed to a red X.

I'm not sure which host is trying a icmp request, but it seem to be stopped. Does the new boinc client require icmp traffic too? There is no rules that allow the other hosts icmp access through the firewall.

Hm...
I tried this from the windows machine: "can't connect to..."

Then I tried it from a linux host at the same network as the "bad" server: "./boinccmd: error while loading shared libraries: libssl.so.0.9.8: cannot open shared object file: No such file or directory"

Then I tried it on the "bad" host itself: "Authorization failure: -155".

I have tried with and without the remote_hosts.cfg without any luck.

That does seem to show port 31416 isn't open between the windows & Linux host. Otherwise you would have gotten the "Authorization failure" message from there as well.

Is that host command line only or does it have a GUI environment installed? If there is a GUI environment. Does BOINC Manager run & connect to the client correctly? If it doesn't I would suspect gui_rpc_auth.cfg is somehow damaged or unreadable by the client apps. Do they run under an account that can not read that file?


The port is open, otherwise I would not have contact with the other hosts. And the firewall log show that the connection attempt is accepted.

It's only the window machine that has the GUI environment. The other host don't even have a monitor attached, so no need for GUI environment.

The installation and the client is running under my regular user, as on all the other hosts.
