Conditional Socket connection acceptance

[Pranith Vanaparthi]

Hi 

I am trying to block socket connection establishment from a IP by keeping a threshold count for a single IP. I am currently using SimpleChannelInboundHandler for message consumption.

Can some one help me in finding a reference to achieve this. 

Thanks in advance !!

If you really need to “block” the socket connection establishment you will need to use something like iptables or any other firewall. With netty you could just close it once you accepted it in channelActive(…).

For iptables see:

Thanks Norman !!

I am able to achieve with below approach.

Also is there a way to identify the source of Netty connection i.e what I mean is there a way to identify from where the socket connections are coming from. If there is a way in Netty I can set this at client while establishment of connection. I can get the same at server at channel active and verify whether it is a valid source.

Here I am trying to identify client level issue/from a external source in case of multiple channel connects
