YNQ is a compact SMB server and client stack created by Visuality Systems, implemented in ANSI C, and tailored to operate on embedded systems, IoT devices, or platforms that do not run Windows, while ensuring seamless interaction with Windows computers. It facilitates remote file management functions such as writing, editing, copying, deleting, and updating files over a network without the necessity of transferring full files locally, all while being resource-efficient to suit limited environments. Fully supporting all SMB dialects from NTLM 0.12 to SMB 3.1.1, YNQ also guarantees backward compatibility, enhancing its utility across various SMB frameworks. The stack includes robust security protocols such as Kerberos for domain joining and delegation, NTLM/NTLMv2, message signing, SMB encryption, and pre-authentication integrity, ensuring secure data transactions. YNQ's modular design consists of four main product components: the Standalone Client, Corporate Client (which features Active Directory registration), Standalone Server, and Corporate Server, allowing for flexible deployment options in diverse settings. This versatility makes YNQ an ideal choice for organizations looking to integrate SMB functionality into their non-Windows environments.
