I am trying to send json messages to a port on a linux server from a remote server running a .net program. I have one implementation running with successful incoming messages to port 1514. I tried to replicate the same thing but just to another port but cannot get it to work as I get the following error:
No connection could be made because the target machine actively refused it xxx.xxx.xxx.131:1521
I tried a few things I found online. I checked the firewall settings and there were no restrictions. I then added a line to accept incoming connections but this did not help. I have a logstash installation to which I am sending these messages. I cannot recall what I did in the initial installation and if I specifically set up the port to listen. I would appreciate any ideas on how to diagnose and solve this issue.
ip addr
iptables -vL
netstat -nlptu
Is this a logstash configuration issue or linux network setting?

Hi.
I am writing client - server application using TCP sockets.
I need some very basic functionality, namely: how to check if another "participant" of the connection is still present?
I want to handle situations, when client is gone, or server breaks down, etc. (25 Replies)
