How do you sniff port traffic?

The most reliable way to sniff traffic is to use a network tap. A network tap is a “bump-in-the-wire” device designed only to copy traffic passing through it to a monitor port. You typically insert a network tap inline between two nodes in a network, such as between your firewall and your first switch.

How to use SOCAT proxy to intercept Unix domain socket?

Everything works fine untill I introduce a socat proxy in between. The server listens on /tmp/unixSockSendFd, socat connects to it ( UNIX-CONNECT:/tmp/unixSockSendFd ), and creates another Unix domain socket ( UNIX-LISTEN:/tmp/unixSockSendFe,mode=775,reuseaddr,fork ), on which the client connects.
