The GitHub repository was created later, in 2010, as the project moved into the modern public-forge era. The project is written primarily in C++ and presents itself as an advanced IRC bouncer. Its README documents the core operating model: data under ~/.znc by default, znc.conf under configs, module data below the data directory, and extra modules loadable from user or installation paths. ZNC's module system became one of its defining features. The README documents C++ modules built with znc-buildmod plus Perl and Python module support through ModPerl and ModPython. That gave administrators a way to extend a bouncer into web administration, logging, notifications, and network-specific behavior. ### 採用の歴史 ZNC became a standard answer to IRC's ephemerality. IRC clients traditionally only see messages while connected; a bouncer keeps the server-side session alive and lets one or more clients attach later. Opensource.com describes ZNC as a relatively popular and well-understood IRC bouncer for this problem. ZNC's history is tied to changes in IRC client expectations. As clients and extensions improved buffer playback and timestamps, ZNC moved from simply keeping a nickname online toward preserving a multi-client chat session that felt less transient. It also remained relevant for bridges, where users wanted Matrix or other systems to connect through an existing IRC identity. ### 使われ方 A user runs znc as a daemon, creates one or more users and networks, then points IRC clients at the ZNC listener instead of directly at the IRC network. The client authenticates to ZNC, and ZNC connects onward, maintains channels, and replays buffered messages after reconnects. Administrators commonly manage it through webadmin or controlpanel rather than editing znc.conf while the daemon is live. The same config file may contain network credentials, which is why the package's configuration and credential locations overlap. ### パッケージ好きにとっての重要性 ZNC is one of the archetypal always-on Unix userland daemons: small enough for a shell account or VPS, old enough to carry IRC culture, and modular enough to become personal infrastructure. It matters to package nerds because it captures the pre-SaaS habit of solving chat persistence with a daemon you own, a config file in your home directory, and a client protocol that still works with many front ends. ### タイムライン - 2004-07-20: ZNC history records the first commit timestamp. - 2000s: ZNC develops as an alternative to earlier IRC bouncers such as psyBNC. - 2010-01-09: The znc/znc GitHub repository is created. - 2010s: ZNC's module ecosystem, web administration, SSL/TLS use, and client buffer behavior become central to everyday IRC bouncer use. - 2020s: ZNC remains a maintained IRC bouncer and a common bridge point for persistent IRC sessions. ### Related projects - psyBNC is the older IRC bouncer ZNC is often compared with historically. - soju, IRCCloud, Quassel, The Lounge, and Heisenbridge occupy adjacent persistent-chat, bouncer, or bridge roles. - HexChat, WeeChat, mIRC, and other IRC clients are common front ends that can connect through ZNC. ### ソース - - - - - - ## セキュリティノート formula declares a Homebrew service. - **Geiger リスク:** orange / 中 - formula declares a Homebrew service ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials.
