In general, a physical server will have multiple IPs, such as a loopback IP value of 127.0.0.1, and an intranet IP value of 192.168.1.100. So which IP is given to esb-client so that the latter can make service request
NMAP provides four basic functions (host discovery, port scanning, service and version detection, OS detection) and a rich scripting library. Nmap can be used for simple network information scanning, but also in high-level, complex, specific environment: such as scanning a large number of hosts on the Internet, bypassing the firewall/ids/ips, scanning web sites, scanning routers and so on.Briefly review Nmap simple scanning method:Full Scan: nmap-t4-a
Although IDS has some defects, we can see that hackers and viruses related to network security depend on the network platform, if hackers and viruses can be cut off on the network platform, the security can be better guaranteed. In this way, the interaction between network devices and IDS devices has emerged.
IDS is associated with network switching devices. When a switch or firewall is running, information about various data streams is reported to a security device. The IDS system can detect
attacks.

IDS Although there are some flaws, but in a different perspective, we can see that all kinds of related network security hackers and viruses are dependent on the network platform, and if the network platform can cut off the transmission of hackers and viruses, then better guarantee security. In this way, network equipment and IDS equipment linkage has emerged.

, the method returns a socket object that establishes a leased line connection to the client. Do not use the program to create the socket object. The two sockets that are connected are data exchanged in IO streams, and Java provides the input stream object that Socket.getinputstream returns the socket. Socket.getoutputstream returns the output stream object of the socket.2.3,TCP program Examples of server programs:Import Java.io.InputStream;Import Java.io.OutputStream;Import. ServerSocket;Import
Problem:Ip! is not available to clients when processing client requests using the thread poolReason:Since the Server_loop note loop only adds the connection word sock to the queue, there is no client IP, so each queue callback function can only get sock connection word, no client IPWorkaround:In the queue sock joins the IP also added to the IPs queue, the IPs queue length and queue, and the data stored in t

Required software tools: Snort + Apache + PHP4 + MySQL + Acid 1. the RedHat9.0 release of the system platform installs gcc and related library files. We recommend that you do not install Apache, PHP, and MySQL. We will compile and install them using the source code. For security considerations, you can set iptables to only allow SSH and WWW access. Ii. Software tools required for MySQL4.0.12http: // mysql. secsup. orgSnort2.0.0:
When I checked the security environment of a Centos5.5 server, I found that many IP addresses were maliciously scanning the port on this server. I originally wanted to deploy the snort anti-intrusion environment. Later I found that the snort environment was very complicated to deploy, the above malicious scans can be fully implemented using PortSentry. PortSentry is one of the simplest and most effective to
unacceptable to users, I am afraid to write data into the solution.
Therefore, how to go deep into the above functions in the LINUX system or expand the above functions in the existing soft route firewall has become my business hobby that takes the most time out of my work. I wanted to call it a job, but I think eight hours ago, it is better to call it a hobby.
Because the open nature of the current soft route firewall is not very good, we have to do it on a pure LINUX system. At the beginnin

The strata guard intrusion detection and defense software encapsulates the snort and provides a graphical interface.
Strata guard has high performance requirements on the dependent hardware, mainly to ensure sufficient network forwarding performance while detecting all network traffic. For the free version of strata guard, we can use the following hardware to customize a hardware platform for the intrusion detection and defense system:Processor: AMD 4

To run iptables, you need to select the following options during kernel configuration, whether you use makeconfig or other commands. CONFIG_PACKET-allow the program to directly access the network device (note: The most common is the network card), such as tcpdump and snort need to use this function. Strictly speaking, iptables does not need CONFIG_PACKET,
