Managed TFTP server is a TFTP server. The main TFTP class runs without modifications on Mono. It works both in IPv4 and IPv6 mode. It has correct retry behavior. It supports the following TFTP options: block size, transfer size, and timeout. It's possible to run in single port mode, which ensures that only port 69 will be used for TFTP transfers, simplifying firewall and router configuration. It supports many concurrent transfers. It runs as a Windows service. It supports multiple TFTP servers on different endpoints, each serving its own root directory. It has an advanced MSI-based installer. It logs to the windows event log. It has a permissive MIT license so it can be used in commercial projects.
radns is a small, portable client-side implementation of the RDNSS option in IPv6 Router Advertisements (RFC 5006) that is used to get the address of a resolving DNS server. It listens for Router Advertisements with the Recursive DNS Server (RDNSS) option and stores the addresses in a file following the same syntax as resolv.conf. It optionally calls a script to handle, for instance, DHCP clients that compete for ownership of /etc/resolv.conf or to set the DNS server on systems that don't use resolv.conf at all. It can be easily integrated with the resolvconf(8) program.
