The iThena distributed project concerns experimental mapping of network structures included in the Internet. The project is in closed beta phase. Currently, the only application available in the project (iThena CNode) performs a sequence of traceroute procedures from client computers. The resulting data is sent back to the server and submitted to the main database, where it can be further analyzed.

Currently the main supported and recommended platform is x86_64-pc-linux-gnu. After joining the project, accept the download of test/beta applications in the settings (iThena CNode is a Beta application). This can be changed by checking the appropriate box 'Run test applications?' in 'iThena preferences' in your profile after logging in.

Network structure mapping summaries will be available online.

Geolocation of network points data
One of the important information in network analysis is the geolocation of network points data.

There is no generally available, one coherent database covering very precise data.

The problem is well known by engineers and researchers.


There are of course some (not perfect) solutions but often the error is big.

I will probably implement a mechanism enabling the platform user to provide location information for a given client.

This is a longer planning period.

Also remember that providing such information is only optional.
This will definitely not be a requirement.

If you have questions or concerns, I encourage everyone to discuss.

Technical breaks in the operation of the BOINC server
I plan to introduce a lot of changes at the beginning of January.

These changes may initially cause system instability.

I need to transport the BOINC server to another location.
It will be associated with a minimum of two longer breaks.

Probable break dates:
1) Today (29/12/2019) in the evening CET [probably several hours];
2) Saturday (04/11/2020) in the afternoon CET [probably several hours];

There are no special long breaks planned between these breaks [there may be smaller, unplanned technical problems].

I will inform you about work and possible changes.

Possible performance issues
I found problems with server performance / availability on the Internet. I will analyze the problem.

For interesting observations, please contact the forum or my email (lswierczewski at ithena.net).

Sorry for problems ;)

Badges for beta stage - iThena CNode
Today I introduced first badges for users (for beta stage).

We have three degrees of beta stage badges:

- bronze:
- silver:
- gold:

We have the following thresholds for these badges:

Gold badge for beta stage >= 0.10 total credit
(average 30030 wu at 0.00000333 credit per wu)

Silver beta badge >= 0.025 total credit
(average of 7507 wu at 0.00000333 credit per wu)

Bronze badge for beta stage >= 0.010 total credit
(average of 3003 wu at 0.00000333 credit per wu)

Only the highest possible badge is awarded.

Deadline on January 1, 2020 is probably not bad ;)
We will pre-implement this date.

Badges designed by DoctorNow (forum: https://root.ithena.net/usr/forum_thread.php?id=23&postid=200#200).
