Is it ok for the application (server and client) if there are number of processes in the status of FIN-WAIT-2 (client) CLOSE-WAIT (server) stay in the system for a long time? The time that is even more then timeout for the next connections of those applications.

For the current moment i like netstat and snoop. I dont clearly understand traceroute. Is it possible to specify ports for tracing by it?

systemd-networkd-wait-online.service

SYSTEMD-NETWORKD-WAIT-ONLINE.SERVICE(8) 		     systemd-networkd.service			   SYSTEMD-NETWORKD-WAIT-ONLINE.SERVICE(8)

NAME

       systemd-networkd-wait-online.service, systemd-networkd-wait-online - Wait for network to come online

SYNOPSIS

       systemd-networkd-wait-online.service

       /lib/systemd/systemd-networkd-wait-online

DESCRIPTION

       systemd-networkd-wait-online is a one-shot system service that waits for the network to be configured. By default, it will wait for all
       links it is aware of and which are managed by systemd-networkd.service(8) to be fully configured or failed, and for at least one link to
       gain a carrier.

OPTIONS

       The following options are understood:

       -i, --interface=
	   Network interface to wait for before deciding if the system is online. This is useful when a system has several interfaces which will
	   be configured, but a particular one is necessary to access some network resources. This option may be used more than once to wait for
	   multiple network interfaces. When used, all other interfaces are ignored.

       --ignore=
	   Network interfaces to be ignored when deciding if the system is online. By default, only the loopback interface is ignored. This option
	   may be used more than once to ignore multiple network interfaces.

       --timeout=
	   Fail the service if the network is not online by the time the timeout elapses. A timeout of 0 disables the timeout. Defaults to 120
	   seconds.
