Hi there!

Just got home after a while and found out that my first tasks got no credits so far...
Looking into the result files shows me this:
./ithena_cnode_check_v1.16_x86_64-pc-linux-gnu: error while loading shared libraries: libssh2.so.1: cannot open shared object file: No such file or directory
Is that the reason? If so, how can I fix this?
As far as I'm aware, this lib is already installed on my Ubuntu version, but I'm not completely sure now...

Edit:
First post in a brand new forum - a premiere for me.. ;-)

Many thanks for the activity! :)

Credits are granted but they are very small amounts - e.g. 0.0000001 credits. This problem will be fixed - the application is in a very initial phase.

You can try to install (Ubuntu):

sudo apt-get install krb5-config libkrb5-dev libssl-dev libsasl2-dev libsasl2-modules-gssapi-mit
sudo apt-get install libnghttp2-dev
sudo apt-get install libidn2-0-dev
sudo apt-get install libssh2-1-dev
sudo apt-get install libpsl-dev
sudo apt-get install libldap2-dev

The application should be statically compiled - I will try to fix this error.

Message 4 - Posted: 23 Sep 2019, 17:45:31 UTC - in response to Message 2.  

I went through installing additional shared libraries (prior to the instructions above)
but I had to roll back as one of them (I don't know which) caused my host resolver to fail.
I will keep an eye out for a static version of the check exe

I also rolled an app_config.xml setting avg_ncpus to 0.0001 to allow my normal tasks to run fully.
So the NCI setup needs some work, though I couldn't spot anything from client_state.xml that was obviously wrong.

This looks very different from the solution I tried to find with installing the libssh2 (again)...
Since I couldn't get it to work anyway (I'm not very familiar with Linux at all and especially installations per Terminal) I wil wait for a static compiled version then.

Today I will add a new version of the app for the linux platform. I hope that there will be no more problems with libraries.

In addition, there is a problem with the mail server - I'll check it.

I don't think the issue i had with my stub resolver was caused by the shared libraries.
The upstream recursive resolver (which I "run") looks like it blacklisted my client.
Does the ithena code issue significant volumes of DNS queries?
If so, you might want to consider how to ratelimit this to a lower level.
If not, I guess i'll have to investigate further...

Maybe yes.
Theoretically, only IP addressing is mainly used.
In today's version of the application I will improve it a bit.

Well ...
While building the new version of the application there were some problems with libraries ...
I don't have strength today - I'm going to sleep soon.
I will test tomorrow;)

New client appears to run - so the static linking works.
Also shows up as NCI now.
I haven't seen a problem with DNS load since - will update if this changes.

I suppose the open question would be: can we have a little more credit now?

Probably some internal function is still using DNS.
I will analyze everything.
Question: Can you remove DNS completely from your system? How does the application react?

I suppose the open question would be: can we have a little more credit now?

I would like to get a fairly stable version of the application first.
There is also the matter of adding statistics.
However, to add statistics, it is best not to be confused about big credits (I think).
We need to set the amount of credits per task (WU length may change).

I cannot remove DNS from my system - it needs to talk to various places that do not have static IPs, so /etc/hosts won't cut it.
But, as I said, the new application version hasn't suffered from the problem yet, whereas previously it was reliably reproducable.

Re: credit - I was thinking on the level of 1 per WU for the current stage instead of 0.000001 (or whatever) - it makes it possible to see what's going on in a slightly different way - but it's your project and therefore your decision.

Meaning you have to finish 1 million WUs to earn one credit....

I don't want to add specific / real credits too soon. Ideally, from the very beginning credit statistics would be exported to statistics systems (BOINCstats, Free-DC, etc.).

The project is in a highly experimental status.

However, I think that on days I will make some changes and add statistics export. After some time, when there is more stability, we will determine real credits.

Sorry for the delays.

Currently, this is probably not a big problem because the system grants a very small amount of credit.

If the system granted millions of credits (before adding to the statistics) it would be a problem ...

At the moment, I'm asking myself if this is possible at all now.
I see every task I had in the past is deleted from my account, and it looks like they are wiped out very quick from the database, when I take a look at the server status.
So how do you plan on crediting tasks from the past, Rysiu?

How to credit tasks from the past? Just a suggestion: move the comma in our present credit three (or more) places...

Nope. It could e.g. mean that you get 1 credit, instead of 0.0001 credit.
It could also mean that you get 12,345 credits instead of 0.00012345 credit...

Old jobs are deleted from the BOINC server database.
The task database would grow too much and slow down the system.

Data is aggregated in another database.
