In this tutorial we learn how to install jdns on Fedora 34.

What is `jdns`

JDNS is a simple DNS implementation that can perform normal DNS queries of any record type (notably SRV), as well as Multicast DNS queries and advertising. Multicast support is based on Jeremie Miller’s “mdnsd” implementation. For maximum flexibility, JDNS is written in C with no direct dependencies, and is licensed under the MIT license. Your application must supply functionality to JDNS, such as UDP sending/receiving, via callbacks. Qt-based command-line tool called ‘jdns’ that can be used to test functionality. jdns 2.0.6 5.fc34 x86_64 54 k jdns-2.0.6-5.fc34.src.rpm fedora A simple DNS queries library https MIT JDNS is a simple DNS implementation that can perform normal DNS queries of any record type (notably SRV), as well as Multicast DNS queries and advertising.
