New: `get_package_proxy_report()` (every line that sets it, per-host overrides, the https sources) and `check_package_proxy(url, expect)` (a fetch with `apt-helper`, past any proxy). `configure_package_proxy(url)` now also comments out other proxy lines, reads the result back and fetches one `InRelease` through the proxy; it fails when apt still fetches elsewhere. Reads run on the exec channel. Requires napalm-device-types 4.22.0; version 0.14.0. - `get_host_firewall()` (napalm-device-types' `HostFirewallMixin`, NetOrk/netork#1344): the host's own netfilter rules — `nft -j list ruleset`, with the tables iptables manages taken from `iptables-save` — as chains and rules in one shape. Read-only, as root, on an exec channel (the nft JSON is one long line).
