00:05:17.176507 74.125.228.54.1270 > 64.254.128.66.25: S 2688560409:2688560409(0) win 16384 (DF) (ttl 46, id 20964) 00:05:17.176700 64.254.128.66.25> 74.125.228.54.1270: S 774583594:774583594(0) ack 2688560410 win 8760 (DF) (ttl 64, id 35473) 00:05:17.302784 74.125.228.54.1270> 64.254.128.66.25:. ack 1 win 17520 (DF) (ttl 46, id 21021)Explanation / Answer
A.a file created, say /etc/hosts.chat.freenode.net, that has the same format as /etc/hosts file and list every IP addresses with name in this file:
Then add to the dnsmasq.conf the following line:
Or put these two lines into /etc/hosts if dnsmasq is set to read in the /etc/hosts.
Then restart dnsmasq
B.communication between two nodes through a channel being visualized as a cable with two male connectors plugging into sockets at each node. Similarly, the term "port" is used for external endpoints at a node, and the term "socket" is also used for an internal endpoint of local inter-process communication (IPC)and this type of communication is called Unix domain socket
