The README explains the core design: write temporary `pf` rules to `/tmp/killswitch.pf.conf`, load them with `pfctl`, and avoid modifying the system default `/etc/pf.conf`. ### Adoptionsgeschichte killswitch has narrower packaging than the other projects in this batch; the Homebrew formula documents it as a macOS VPN kill switch, and the project README focuses on local builds and root-required enable/disable commands. ### Wie es verwendet wird Users run `sudo killswitch -e` to enable firewall rules, `sudo killswitch -d` to disable and restore default rules, or `killswitch --print` to inspect rules before applying them. ### Warum Paket-Nerds sich dafür interessieren killswitch is notable as a small packageable security utility that exposes macOS `pf` behavior through a single CLI, useful for users who want a provider-independent VPN leak guard rather than an application-specific setting. ### Zeitleiste - 2016: vpn-kill-switch/killswitch repository created on GitHub. - 2019: 0.7.0 release published. - 2020: 0.7.1 and v0.7.2 releases published. - 2023: v0.7.3 release published. - 2026: 0.8.x releases published from February through April. ### Related projects - The README links the design to the Packet Filter firewall documented by FreeBSD and to macOS networking tools such as `pfctl`, `sysctl`, `netstat`, `scutil`, and `ifconfig`. ### Quellen - - - - - ## Sicherheitshinweise narrow executable package without higher-risk signals. - **Geiger-Risiko:** grün / niedrig - narrow executable package without higher-risk signals ## Details aus der Quelldatenbank - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** killswitch - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Requirements:** macos - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## Verwandte Links - [Terminal utility packages](https://pkg.so/de/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Networking and protocol packages](https://pkg.so/de/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [Security and crypto packages](https://pkg.so/de/security-crypto-tools/) - Matched security, identity, cryptography, password, signing, or certificate metadata. - [Homebrew utility packages](https://pkg.so/de/brew-utility-packages/) - Matched Homebrew package provider. - [rust](https://pkg.so/de/brew/rust/) - Build dependency declared by Homebrew. - [strongswan](https://pkg.so/de/brew/strongswan/) - Shares pkgdb curated category or tags: cli, network-security, security, vpn. - [openssh](https://pkg.so/de/brew/openssh/) - Shares pkgdb curated category or tags: cli, network-security, security. - [pinentry-mac](https://pkg.so/de/brew/pinentry-mac/) - Shares pkgdb curated category or tags: cli, macos, security. - [ipsw](https://pkg.so/de/brew/ipsw/) - Shares pkgdb curated category or tags: cli, macos, security. - [bettercap](https://pkg.so/de/brew/bettercap/) - Shares pkgdb curated category or tags: cli, network-security, security. - [easy-rsa](https://pkg.so/de/brew/easy-rsa/) - Shares pkgdb curated category or tags: cli, security, vpn. - [zeek](https://pkg.so/de/brew/zeek/) - Shares pkgdb curated category or tags: cli, network-security, security. - [snort](https://pkg.so/de/brew/snort/) - Shares pkgdb curated category or tags: cli, network-security, security. - [ettercap](https://pkg.so/de/brew/ettercap/) - Security-sensitive metadata or terminology overlaps.
