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.

New application, new possibilities, new problems ;)
I will soon be implementing a new application ;)
The application will be called iThena NRT.

The credit problem will be solved.

The tasks for iThena CNode will be phased out.

However, there are many problems.
Initially, iThena NRT will be available as a virtualised environment (VBox/Vmware). You will be able to start a virtual system.

Of course it will also be possible to run it locally.

In addition, the iThena NRT application will require a permanent connection to the Internet.

Performance problems
There are performance problems in system operation.
Today / tomorrow I'll be reconfiguring the database.
Possible problems with system availability.

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.
