get_listening_sockets() in the shape of napalm-device-types' ListeningSocketsMixin, whose ss/cgroup reading is Linux's, and with its rule: read as root first, and without root when that brings nothing back, which the reading reports as `attributed: False`. - FreeBSD: `sockstat -46lq -P tcp,udp`, which sees every socket either way. - OpenBSD: `fstat -n` as root (the sockets nothing is connected to; port 0 is unbound), `netstat -an` without root, as fstat shows a user only their own processes; those sockets come without a process. - Addresses as ss prints them: `*` becomes 0.0.0.0 or :: by family, IPv6 without brackets, a zone (`fe80::1%lo0`) becomes the interface. One entry per socket, the first process holding it. No get_kernel_facts on purpose: KernelFactsMixin reports a Linux kernel's modules and CONFIG_ options, which a BSD kernel does not have. Fixtures recorded on the FreeBSD 15.1 and OpenBSD 7.9 VMs with test listeners on 127.0.0.1 and ::1 (NetOrk/netork#798).
