1) Questions and Answers : Unix/Linux : Model Crashed...Unrecoverable error...segmentation violation (Message 6861)

I couldn't solve the problem. And because nobody could answer this question / solve this problem until now, I deleted the model from my machine. :(
2) Questions and Answers : Preferences : howto delete a host? (Message 3151)

Hi Honza

I was able to delete one of the hosts after I detached it from the project (reset did not fix the problem).
But I'm still not able to delete the other one...

Regards
Markus
3) Questions and Answers : Preferences : howto delete a host? (Message 2989)
Posted 4 Sep 2004 by old_user649
Post:
On two of my hosts, I only got client errors and no usable results. On one host, I have a wrong glibc version and on the other one, I don\'t know what the problem is. But I don\'t have the time to fix that right now.
I would like to delete these hosts from my account.
But whenever I click on \'Delete this host\' in the \'Computer summary\' page of that host, I get the following error:
\'Error: existing results\'

So, is it possible to delete these hosts? They never uploaded any useful informations I think...

4) Questions and Answers : Unix/Linux : kernel panic - preempted kernel (Message 723)
Posted 11 Aug 2004 by old_user649
Post:
For sure, BOINC is running as a 'user space' program.
But in the end, the kernel panic occured, while some other process (I don't know which process) wanted to preempt the model.
If you look at it that way, you are right, when you say, that this isn't a problem of the climate model.

But I look at it a bit in another way: I'm running about 5 linux boxes with a 2.6 kernel since December 2003 (in the meantime, there are about 10 linux boxes...). I compiled all kernels with preempting enabled. Max uptime for the machines are around 100 days. Until now, I have NEVER had a kernel panic before!
I installed the BOINC client yesterday on one of these machines (uptime 25 days with kernel 2.6.7-gentoo-r11). The model was running for 4,5 hours when the kernel panic occured.

Nothing strange is mentioned in the system logs (when there is a panic, there will be written nothing to the logs anymore...).

After all, this is a beta-test - so I think, that all errors should be reported...

5) Questions and Answers : Unix/Linux : kernel panic - preempted kernel (Message 690)

Post:
Last night I had a Kernel panic on one of my linux boxes.

Last Output from the BOINC client seems to be ok:
<pre>...
02r9_100028558 - PH 1 TS 005998 - 05/04/1811 23:00 - H:M:S=0004:32:20 AVG= 2.72 DLT= 2.00

stderr.txt is empty.

In the panic message was mentioned that it was a problem with PREEMPT. While trying to preempt the model-process from the kernel, the kernel panic occured.

Kernel: 2.6.7-gentoo-r11
CPU: AMD Athlon(tm) XP 2600+ (no overclocking)
RAM: 1GB DDR400

Do you need some other informations?

7) Questions and Answers : Unix/Linux : probably a proxy problem (Message 617)
Posted 10 Aug 2004 by old_user649
Post:
I tried with many different settings now. And I found a working one.
If I set the env variable HTTP_PROXY to http://proxy.unibe.ch (without port), then it works.
If I find some time, I will try with some more settings.
But the output of netstat is still a bit confusing:
<pre>
# netstat -lnpt
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
tcp 0 0 0.0.0.0:31416 0.0.0.0:* LISTEN 15050/boinc_4.02_i6

8) Questions and Answers : Unix/Linux : probably a proxy problem (Message 552)
Posted 9 Aug 2004 by old_user649
Post:
From a web browser, it is no problem to reach http://climateprediction.net

But to pings, it does not respond.
<pre>
$ ping climateprediction.net
PING climateprediction.net (137.108.64.33) 56(84) bytes of data.

--- climateprediction.net ping statistics ---
174 packets transmitted, 0 received, 100% packet loss, time 172994ms
</pre>
I do not have any problems at home (to pings, the server does not respond even from home - so that should be no problem). It would be very sad if I can't use the power of the machines inside the university...

As I have seen right now, the boinc client is listening on a tcp port.
<pre>
tcp 0 0 0.0.0.0:31416 0.0.0.0:* LISTEN 2129/boinc_4.02_i68
</pre>
This port will be blocked by the firewall for sure. Does anybody know a workaround?

I can\'t attach my boinc client to the climateprediction project.
I\'m in the University and behind a proxy-server and firewall. Does that matter for boinc?

I get the following output:
<pre>

I tried with an environment variable HTTP_PROXY. I also set the proxy in the client_state.xml. But I always get the same error.
Or is the URL wrong? Or is it another problem?
