I want to ping servers. Lost connection. I want to find out why this is happening. Is it possible to ping a server on different interfaces? Let's say I have wlan0 besides eth0 - how to ping?

Answer 1

netstat?
-b Display the executable involved in the creation of
each connection, or the port that is waiting. Sometimes known
executables contain multiple independent
components. Then the sequence of components
involved in the creation of the connection, or the waiting port is displayed. In
this case, the name of the executable file is below in brackets
[], above is the component it calls, and so on until
TCP/IP is reached. Note that this approach
can take a long time and requires sufficient permissions.
netstat -bno
