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.

Tomorrow (November 1, 2019) I will configure database replication and modify power issues. I will have to shut down the BOINC server for a certain time that day. The website and all BOINC services will not be available.

October 14, 2019: Backend / storage - planned tests / changes
Tomorrow (October 14, 2019) I plan to test the changes on the backend / storage side.

In the evening, from 18:00 UTC and later, serious accessibility problems are possible (the server may be offline).

Small changes on the server
In recent days I have not introduced any major changes to the system.

Yesterday and today I spent more equipment issues (infrastructure etc.).

Today, I will probably make small changes on the server. The project may be unavailable for several hours (evening hours - 07.10.2019 UTC).

ARM platforms
I added support for ARM platforms.

Platforms added:


All platforms require wget to be installed.
I noticed that sometimes problems may occur (I will make corrections to the implementation).
