I am running a secure webserver which requires http, https,mysql, and sshd. All the necessary ports are open for each service. However the following ports are also open and I am not sure what they are needed for
rpcbind on port 111
sometimes-rpc3 on port 32770
sometimes-rpc5 on port 32771
all other ports are closed. Can someone tell me what these may be needed for.
thanks
