Publisher: RosRunner Licensing inquiries: [email protected] IMPORTANT — READ CAREFULLY. This is a proprietary, commercial software license, NOT an open-source license. By downloading, installing, copying, referencing, or otherwise using RosRunner, its included components, or its associated documentation and source files (the "Software"), you agree to be bound by the terms below. Components with a separate license remain subject to that license; see section 6. 1. Grant of License. Subject to a valid, paid commercial license agreement between you and the copyright holder, you are granted a non-exclusive, non-transferable license to use the Software in accordance with that agreement. Written evaluation or trial permission from the copyright holder applies only within its stated scope and duration. Except for such permission or an applicable prior license, no rights are granted without an agreement. The applicable agreement or purchase terms specify the licensed product, users or installations, duration, permitted use, update entitlement and support. This document does not promise a particular price, trial period, perpetual updates or support. A RosRunner application license does not by itself grant rights to redistribute its components or obtain source code. 2. Restrictions. Except as expressly permitted by your license agreement or by mandatory applicable law, you may NOT: (a) redistribute, sublicense, sell, rent, or lease the Software; (b) modify, adapt, or create derivative works for distribution; (c) reverse engineer, decompile, or disassemble the Software; (d) remove or alter any proprietary notices. 3. No Warranty. TO THE EXTENT PERMITTED BY APPLICABLE LAW AND EXCEPT AS EXPRESSLY AGREED IN WRITING, THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NONINFRINGEMENT. 4. Limitation of Liability. TO THE EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL THE COPYRIGHT HOLDER BE LIABLE FOR ANY CLAIM, DAMAGES, OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT, TORT, OR OTHERWISE, ARISING FROM, OUT OF, OR IN CONNECTION WITH THE SOFTWARE OR ITS USE. 5. Protocol Note. The Software interoperates with MikroTik RouterOS via Winbox, RouterOS API, SSH and REST management interfaces. MikroTik is not affiliated with this Software and provides no compatibility guarantee; see README.md. 6. Third-Party and Prior Licenses. Third-party components retain their own copyright notices, licenses and permissions. This license does not replace or restrict those terms. See NOTICE and the license texts in licenses/, also available from RosRunner's license information window. Separately licensed components in this repository, including Rosbox, retain their own licenses. Nothing in this document revokes rights validly granted under a prior applicable license. Mandatory statutory rights are not excluded.

Their upstream license texts and notices are included in licenses/. The license inventory there identifies the source versions and URLs; update it when changing dependencies or runtime packs. Full license texts (including upstream copyright notices): licenses/Velopack-LICENSE.txt licenses/SSH.NET-LICENSE.txt licenses/BouncyCastle-LICENSE.txt licenses/Microsoft.Extensions-LICENSE.txt licenses/Microsoft.Extensions-THIRD-PARTY-NOTICES.txt licenses/NET-Runtime-LICENSE.txt licenses/NET-Runtime-THIRD-PARTY-NOTICES.txt licenses/WindowsDesktop-LICENSE.txt The license texts are embedded in RosRunner and can be read offline by clicking the version information in the status bar.
