SNMP programming is being studied recently for more effective network management. Recently, the focus is on five basic SNMP operations (see RFC1157 documentation, that is, get-request get-next-request get-response set-request trap), but it is not intuitive to read only the description in the book. It is better to see the actual operation, the Sniffer software can provide us with good information in this regard. Next I will introduce the five basic ope
Editor's note: Sniffer is often used by attackers after they intrude into the system to collect useful information. Therefore, Preventing System breakthroughs is critical. The system security administrator should conduct regular security tests on the managed networks to prevent security risks. At the same time, you must control the number of users with considerable permissions. Remember that many attacks often come from inside the network.

How to find a Sniffer in the NetworkOne simple answer is that you cannot find it. Because they leave no trace at all.Because sniffer is so arrogant and quiet, it is difficult to explain how to know if there is any sniffer. It is a convincing reason to prove that your network has two sniffer types:Packet Loss Rate of ne

Sniffer has always been an annoying hacker tool because it is a static attack software and its existence does not leave any trace, therefore, it is difficult for people to pull it out. However, it is quite harmful (it is like a monitor, and your "every action" is under its surveillance, you say it is not very harmful ). Therefore, it is necessary to find a way to check whether there is sniffer in the networ

Sniffer is translated as a sniffer. It is a threatening passive attack tool! You can monitor the network status in an attack. Data Flow and information transmitted over the network can be attacked and intercepted through network monitoring. Hackers often like to use it to intercept user passwords!Sniffer can be divided into two types: one is hardware and the othe
