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.

Long-term storage issue: LTO / Linear Tape-Open
There are some storage issues that arise.
We are missing some LTO drive/streamer in the infrastructure.
An LTO3 or LTO4 drive would solve a lot of the long-term storage issues at this point.

If someone has an unused LTO3 or better LTO4 drive and could donate it, we would be very grateful :)
Direct email contact: lswierczewski [at] cybercomplex [dot] net

This type of help would be very useful, and there are sometimes hardware replacements in various companies.
