InspIRCd is a modular Internet Relay Chat (IRC) server written in C++ for Linux, BSD, Windows and macOS systems.
It was created from scratch to be stable, modern and lightweight. It provides a tunable number of features through the use of an advanced but well documented module system. By keeping core functionality to a minimum we hope to increase the stability, security and speed of InspIRCd while also making it customisable to the needs of many different users.
And after all it’s free and open source.
InspIRCd v2.0.24 is now available, download it from the releases page. This release contains minor bug fixes, including fixes to the build system and module manager to work on newer perl versions (>5.24.1) which are common on newer systems. All users are recommended to upgrade.
InspIRCd v2.0.23 is now available, download it from the releases page. This release fixes a serious security vulnerability in m_sasl in combination with any services that support SASL EXTERNAL. To be vulnerable you must have m_sasl loaded, and have services which support SASL EXTERNAL authentication. If you are affected and can not immediately upgrade, it is recommended to unload m_sasl, or otherwise disable all SASL EXTERNAL authentication in services.
InspIRCd v2.0.22 is now available, download it from the releases page. This release fixes the issues discovered since 2.0.21, containing important stability and correctness related fixes and better support for newer compilers (GCC 6.x). There is a new config option <options:hideulinekills> that can be used to hide server notices for KILLs done by U-Lined servers (services). A desync issue has also been fixed which caused some channel bans to be not synced on burst for empty non-permanent channels in some cases.
InspIRCd v2.0.21 is now available, download it from the releases page. This is a bugfix only release, fixing issues discovered since 2.0.20. An issue has been fixed in m_namedmodes which allowed non-opers to obtain the key (+k) of a channel. This release also features build system fixes, more aggressive DNS cache pruning, increased default DH bit size to 2048 when generating DH params via configure, increased compatibility during CAP negotiation with some clients and various documentation enhancements.
I’m pleased to announce that we’ve got a brand new website developed by Roland Hegedus (syf` on IRC). Big thanks to Roland for his work on the site!
InspIRCd v2.0.20 is now available, download it from the releases page. This release fixes an issue with STARTTLS handling which can potentially cause a crash. Only servers using m_ssl_gnutls with STARTTLS enabled are affected, m_ssl_openssl is unaffected. To mitigate this problem, disable STARTTLS by setting <gnutls starttls="off">.
InspIRCd v2.0.19 is now available, download it from the releases page. This release fixes the issues discovered since 2.0.18, containing multiple important stability and correctness related improvements, including a fix for a bug which allowed malformed DNS records to cause netsplits on a network. Triggering this issue is non-trivial and it may not occur in all circumstances, but all users are advised to upgrade. If that’s not possible, disabling DNS lookups for connecting users (nouserdns setting) mitigates the problem.
InspIRCd v2.0.18 is now available, download it from the releases page. This release fixes the issues discovered since 2.0.17. Several new config options are now available for OpenSSL making it possible to disable SSLv3 among other things. For details please see the updated OpenSSL wiki page.
InspIRCd v2.0.17 is now available, download it from the releases page. This is a bugfix-only release, bringing several improvements and fixes for the Windows version, better compiler support and stability and correctness related improvements.
InspIRCd v2.0.16 is now available, downloads are here. This is a bugfix-only release, containing several stability related and correctness improvements. An issue has also been fixed that prevented clients using NSS for SSL/TLS such as Pidgin (via libpurple), ChatZilla, Instantbird, etc. from reconnecting to a server using OpenSSL after disconnection. See this bug report for more information.
