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, windows_intelx86 and windows_x86_64. After joining the project, accept the download of test/beta applications in the settings (all currently applications is in a Beta stage). 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.

Two applications are currently active: iThena CNode and iThena PERF.
The iThena CNode application tests delays, possible losses and routing of network packets.
The iThena PERF application mainly tests bandwidth to defined endpoints.

Dedicated DNS servers available (as part of optimization)
Applications (especially CNode) can now make significant use of DNS servers.

To avoid overloading other servers (not necessarily your ISP) you can use our DNS servers:

Location: Germany/Frankfurt
IPv6: 2001:41d0:701:1100::452

Location: Canada/Beauharnois
IPv6: 2607:5300:101:0:0:0:0:75d

Location: Poland/Warsaw
IPv6: fe80::250:56ff:fea9:8da0

Location: Australia/Sydney
IPv6: 2402:1f00:8100:400::125a

You can also set up your own DNS server (or just DNS cache) on your LAN.
This is especially important if you have several/many BOINC clients and CNode app.
You can check which of the above DNS will be the best (geolocation).

NMN magazine: "Internet security - reality or only illusion?" (Polish title: "Bezpieczeństwo w sieci - rzeczywistość czy jedynie iluzja?")

An interview appeared in NMN magazine: "Internet security - reality or only illusion?" (Polish title: "Bezpieczeństwo w sieci - rzeczywistość czy jedynie iluzja?").

Unfortunately, the content is only available in Polish.

However we strongly encourage you to read the content - you can find some words also about the iThena project.

Q1 2021: Planned hardware upgrade of the iThena BOINC platform
A major hardware upgrade of the BOINC server is planned for Q1 2021.

Currently, the BOINC platform shares hardware resources within the framework of virtualization.

I plan to separate the BOINC platform into dedicated hardware resources (dedicated server).

This server will probably run on 15k SAS drives (mirroring) with double socket Intel Xeon CPU.

If somebody has unnecessary SAS hard drives (15k or even 10k) or some RAM (DDR3 ECC/non-ECC), these are components that can be very useful in hardware system;)

In case someone would like to donate this type of hardware to the project or have other interesting components (also network equipment) can contact me by email: lswierczewski@cybercomplex.net

In Q1 2021, we also plan to make a significant upgrade of the Internet access link.

The exact timing of the changes is not yet known.
