New page

= netstat =

Gives an overview of network activities and displays which ports are open or have established connections. The netstat tool is essential for discovering network problems.

== Use ==
<code>netstat</code> show lists of ''active'' connections

The first list shows internet connections:
'''Proto''' – Protocol of the connection (TCP, UDP)
'''Recv-Q''' – Receive queue of bytes received or ready to be received
'''Send-Q''' – Send queue of bytes ready to be sent
'''Local Address''' – Address details and port of the local connection, an asterisk (*) in the host indicates that the server is listening and if a port is not yet established
'''Foreign Address'''– Address details and port of the remote end of the connection, an asterisk (*) appears if a port is not yet established
'''State''' – State of the local socket, most commonly ESTABLISHED, LISTENING, CLOSED or blank

The second list shows "Unix Domain" open sockets:
'''Proto''' – Protocol used by the socket (always unix)
'''RefCnt''' – Reference count of the number of attached processes to this socket
'''Flags''' – Usually ACC or blank
'''Type''' – The socket type
'''State''' – State of the socket, most often CONNECTED, LISTENING or blank
'''I-Node''' – File system inode (index node) associated with this socket
'''Path''' – System path to the socket
