Its official site presents it as a companion to tcpdump: capture traffic into pcap files, edit the packets, then regenerate that traffic on a live network. ### プロジェクトの歴史 The official changelog begins with version 0.1 on January 25, 2006, initially using libpcap and libnet and tested on FreeBSD. By version 0.2, the project removed the libnet dependency and centered on libpcap. The 2006 public release added man pages for bittwist, bittwistb, and bittwiste. Later releases consolidated the tool around the packet generator and editor, with version 2.0 in 2012 adding a Mac OS X distribution and ending the old web edition and bridge maintenance. ### 採用の歴史 The input package-manager data lists Homebrew, Debian, Ubuntu, MacPorts, and openSUSE packaging, which matches Bit-Twist's official cross-platform positioning for Windows, Linux, BSD, and macOS. Version 4.x in 2024 refreshed distribution artifacts across Windows, Linux, BSD, and macOS and added modern network-test features such as jumbo frames and VLAN editing. ### 使われ方 Users typically combine bittwiste and bittwist: create or edit a pcap with bittwiste, then send it on an interface with bittwist. The official examples include throughput testing, firewall testing, SYN flood simulation, ARP-cache-poisoning demonstrations, and jumbo-frame testing in controlled networks. The tool is aimed at administrators and network testers who need repeatable packet streams for firewalls, IDS/IPS, routers, switches, load balancers, and troubleshooting. ### パッケージ好きにとっての重要性 Bit-Twist is package-nerd interesting because it is a small C-era Unix networking tool that survived across libpcap, WinPcap/Npcap, BSD, macOS, and Linux packaging rather than becoming a one-platform appliance utility. Its split between a pcap editor and a sender reflects classic command-line composability: tcpdump captures, bittwiste edits, bittwist replays. ### タイムライン - 2006-01-25: Version 0.1 skeleton program released. - 2006-04-11: Version 0.7 public release with man pages. - 2007-10-26: Version 1.0 increased generator throughput option up to 10 Gbps. - 2012-04-21: Version 2.0 added Mac OS X distribution and revised platform support. - 2023-05-24: Version 3.0 updated homepage to bittwist.sourceforge.io. - 2024-11-01: Version 4.7 released with IEEE 802.1ad Q-in-Q VLAN editing support. ### Related projects - tcpdump is the capture-side tool Bit-Twist explicitly complements. - libpcap is the packet capture/transmission library Bit-Twist is built around. - Npcap is listed by the official site as the Windows prerequisite. ### ソース - - - - - source_facts.package-manager ## セキュリティノート narrow executable package without higher-risk signals. - **Geiger リスク:** グリーン / 低 - narrow executable package without higher-risk signals ## 他のパッケージマネージャ記録 - Debian apt - bittwist - 4.7+ds-2: normalized package name match | Debian stable package indexes: bittwist from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | libpcap based Ethernet packet generator | https://bittwist.sourceforge.io - Ubuntu apt - bittwist - 3.8-1build2: normalized package name match | Ubuntu 24.04 LTS package indexes: bittwist from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | libpcap based Ethernet packet generator | https://bittwist.sourceforge.io - zypper - bittwist - 3.8-2.8: normalized package name match | openSUSE Tumbleweed package metadata: bittwist from https://download.opensuse.org/tumbleweed/repo/oss/repodata/50b07339cb64c8ed4091bdbabddadc1ff5737b090e478818a195b40d8a3292861a879139b4a3987c31109699fde9fbf4a716367ddf4eef77da75f96e3193d6ed-primary.xml.zst | A libpcap-based Ethernet packet generator | https://bittwist.sourceforge.io - MacPorts - bittwist: normalized package name match | MacPorts ports tree: net/bittwist/Portfile from https://api.github.com/repos/macports/macports-ports/git/trees/master?recursive=1 ## Combined YAML source View the package source record on GitHub.
