It packages asynchronous iSCSI and SCSI task handling into a reusable library plus command-line tools for target discovery, inspection, testing, and data operations. ### Project history The iSCSI protocol was standardized in RFC 3720 in 2003 as SCSI over TCP, then consolidated in RFC 7143 in April 2014. libiscsi implements the client side of that protocol, with an asynchronous core, a synchronous convenience layer, utility programs, examples, and an iSCSI conformance test tool. The repository tags show libiscsi 1.1.0 in December 2011 and a long sequence through the 1.x series. The README describes the project as a work in progress aiming to cover iSCSI session establishment and maintenance plus low-level SCSI CDB construction and data-in parsing. ### Adoption history libiscsi is adopted by distributions and storage tools that need user-space iSCSI client behavior without depending on kernel initiator workflows. Its README also includes patches for making external packages such as SG3-UTILS and MTX iSCSI-aware, which points to its role as a library layer for storage utilities. ### How it is used The utilities cover operations such as logging in to targets, enumerating targets and devices, inquiry, capacity checks, performance tests, persistent reservations, and conformance tests. The README documents iscsi:// and iser:// URL formats, CHAP credentials, bidirectional CHAP, IPv6, header digest, and data digest support. ### Why package nerds care For package maintainers, libiscsi is a useful user-space storage protocol toolkit: small enough to ship as a library and CLI bundle, but deep enough to exercise SCSI/iSCSI edge cases through iscsi-test-cu. It is also a good example of a package where command-line URL handling, optional credentials, and protocol conformance tests matter more than a visible desktop UI. ### Timeline - 2003-04: RFC 3720 standardized iSCSI as SCSI over TCP. - 2011-12-24: The repository records libiscsi 1.1.0. - 2014-04: RFC 7143 consolidated the iSCSI protocol specification. - 2025-07-15: The repository records libiscsi 1.20.3 with event-loop write and bug-fix changes. ### Related projects - Related projects include the IETF iSCSI RFCs, SCSI standards, SG3-UTILS, MTX, STGT test-target workflows, CUnit for conformance testing, and packages that need user-space iSCSI access to storage targets. ### Sources -
