'iptraf-ng' is a TUI network monitor; it's a really easy way of watching bandwidth on each of your interfaces, and has modes to split between say IPv4/IPv6/TCP/etc, or packet size; and shows you all the IP connections currently transferrign thing, or all the ethernet devices currently doing stuff.

apparently the TCP/IP stack that i designed is used in seL4! in the microkit library, specifically (sel4-async-network)

Off-Path TCP Exploits: PMTUD Breaks TCP Connection Isolation in IP Address Sharing Scenarios
Path MTU Discovery (PMTUD) and IP address sharing are integral aspects of modern Internet infrastructure. In this paper, we investigate the security vulnerabilities associated with PMTUD within the context of prevalent IP address sharing practices. We reveal that PMTUD is inadequately designed to handle IP address sharing, creating vulnerabilities that attackers can exploit to perform off-path TCP hijacking attacks. We demonstrate that by observing the path MTU value determined by a server for …

Solution: System Settings > Wifi > click "details" next to your wifi network > select TCP/IP tab. Change "Configure IPv6" setting from Off to "Link-Local Only".
🤷‍♂️ No effing idea why.

Joyride: Rethinking Linux's network stack design for better performance, security, and reliability
Contemporary distributed computing workloads, including scientific computation, data mining, and machine learning, increasingly demand OS networking with minimal latency as well as high throughput, security, and reliability. However, Linux's conventional TCP/IP stack becomes increasingly problematic for high-end NICs, particularly those operating at 100 Gbps and beyond. These limitations come mainly from overheads associated with kernel space processing, mode switching, and data copying in th…
