has been completed. To prevent excessive machine load, you can also configure a master multi-slave service, theMaster node is only responsible for write operations, theslave node only provides read operations. However, there are several questions:A. can the server be the master server, i.e. can I write from the server? Try it:> Db.testdb.insert ({"Test3": "Item3"}) Writeresult ({"Writeerror": {"code": Undefined, "errmsg": "Not Master"} })As you can see,the slave node is not writableB. if maste

One method that attackers often use to obtain network information is to impersonate a trusted member of a network. The attacker cheats the source IP address in the packet and sends it to the internal network. An attacker would only need to change
