I want to try and get to use NIFI, but I am not bothered with Twitter for the moment, instead I want to use a Telnet output called a "Dx Cluster". UNless you are radio Ham, then you probebly do not care about this too much. But it is a telnet protocol.
I can access this via telnet at a host gb7mbc.spoo.org:8000
A username of your ham radio calsign is needed.
Netcat to Port
I tried to simply do the following command
echo "a45wg" | nc gb7mbc.spoo.org 8000
This connects and seems to hang.
So, we now try
echo "a45wg" >> command.txt mkfifo dummy cat command.txt dummy | nc gb7mbc.spoo.org 8000
This creates a fifo device called dummy, which as it is empty never completes the cat. Hence the nc link is kept open.
