[44net] New version 1.2.4c of Echolink proxy/relay software

For those running an Echolink proxy/relay farm or interested in doing so: I have released a new version 1.2.4c of my Echolink proxy/relay software, which is now available on my website https://pe1chl.nl/ as https://pe1chl.nl/Softw/elproxy.tar.gz New in this version: - fixes in the relay protocol by K1RFD (Echolink) - changed the TCP queue management, now it is no longer required to tweak the   TCPQueueHighWater setting in the config file (setting can be deleted) and the   TCP send queue sizes in the system parameters (sysctl.conf) - rewritten the use of select() to the Linux epoll(7) feature, should be more efficient When you are running relays for Echolink, please update the software as it resolves some issues for mobile users that were reported to K1RFD. When running only proxies, the update is not that important unless you experience the TCP queue issue described in the README file of version 1.2.3c and could not completely eliminate it using TCPQueueHighWater. 73, Rob PE1CHL
