Graphical SFTP client and terminal emulator with helpful utilities.

bandwhich is a relatively new terminal bandwidth utilization tool for Linux, *BSD and macOS, written in Rust. It shows the current network utilization by process, connection and remote IP/hostname.

In a world of evolving and targeted cyber threats understanding your attacker’s intentions and tools has never been more crucial. By deliberately maintaining vulnerable systems, or Honey Pots, and letting the attackers in you can analyse their activity and gather intelligence so you can be ahead of the game if you ever have a compromise. When running an SSH Honey Pot you can gain a full log of the commands an attacker attempts to run on your system and any files which they attempt to download and can be a great way to obtain samples of malicious software for analysis or understand the techniques used by an attacker to scour your data.

Formerly known as what, it is a CLI utility for displaying current network utilization by process, connection and remote IP/hostname.

Tailscale creates a virtual network to connect your devices to your services directly, no proxies required.

Here are some tricks for using SSH through a proxy or bastion quickly.

How to run an internet speed test from the Linux command line. We examine two tools that both use the speedtest.net service to test your connection speeds.

SCION is the first clean-slate Internet architecture designed to provide route control, failure isolation, and explicit trust information for end-to-end communication. SCION organizes existing ASes into groups of independent routing planes, called isolation domains, which interconnect to provide global connectivity. Isolation domains provide natural isolation of routing failures and misconfigurations, give endpoints strong control for both inbound and outbound traffic, provide meaningful and enforceable trust, and enable scalable routing updates with high path freshness. As a result, the SCION architecture provides strong resilience and security properties as an intrinsic consequence of its design. Besides high security, SCION also provides a scalable routing infrastructure, and high efficiency for packet forwarding. As a path-based architecture, SCION end hosts learn about available network path segments, and combine them into end-to-end paths that are carried in packet headers. Thanks to embedded cryptographic mechanisms, path construction is constrained to the route policies of ISPs and receivers, offering path choice to all the parties: senders, receivers, and ISPs. This approach enables path-aware communication, an emerging trend in networking. These features also enable multi-path communication, which is an important approach for high availability, rapid failover in case of network failures, increased end-to-end bandwidth, dynamic traffic optimization, and resilience to DDoS attacks.
