the stand-alone mode, xinted mode is also called Internetsuper-server (Super Server). XINETD can listen to multiple specified ports at the same time, when accepting user requests, he can initiate different network service processes to handle these user requests depending on the port requested by the user. You can think of xinetd as a Management server that manages the startup service, decides to hand over a client request to that program, and then in

xinetd. For example: To start the Auth service, open the/etc/xinetd.d/auth profile, change the "Disable=no", and save the exit.Run/etc/rc.d/init.d/xinetd restartTo stop the Auth service, open the/etc/xinetd.d/auth configuration file, change the "Disable=yes", and save the exit.Run/etc/rc.d/init.d/xinetd restart3.

Win7 methods for safely shutting down ports 139, 135, 445, etc. 1. On the Start menu, select Run, enter "Gpedit.msc" and return, and open the local Group Policy Editor. Expand Computer Configuration---Windows Settings---Security settings---IP Security policy on the local computer. 2. To close 135 ports for example (other port operations are the same): Right-click in the right margin of the local Gro

Management of I/O Ports and I/O memory in Linux Port is the address of the register that can be directly accessed by the CPU in the interface circuit. Almost every type of peripherals is performed by reading and writing registers on the device. The CPU sends commands to registers in the interface circuit through these addresses to read the status and transmit data. A peripheral register, also known as an "I/O port", usually includes three categories:

First, the switch types are divided into low-end (SOHO-level) and high-end (enterprise-level ). An important difference between the two is the low-end switch. Each physical port is a logical port, while the high-end switch binds multiple physical ports into one logical port for configuration. In a cisco Network, the switch is eventually stable in the LAN First, the switch types are divided into low-end (SOHO-level) and high-end (enterprise-level ). An

persists until the last sub-section of the three-way handshake arrives. or until timeout (Berkeley time to define this timeout as 75 seconds)If the queue is full when the client SYN arrives, TCP ignores the subsequent incoming SYN, but does not send the RST information to the client because the client is now allowed to retransmit the SYN section, and if an error message is returned, Then the client will not be able to tell whether the server port on the corresponding

Memcache installation is very simple, by default, anyone can access the cached data on the server, so it is very insecure if not processed (there are many issues related to this in the dark cloud)1. First make sure that the firewall on the server is open2.

You can prevent other hosts from accessing certain ports on this computer by Win7 the system's firewall. First, take a look at inbound rules and outbound rules: Inbound is someone else visiting you, outbound is you visiting others. Turn on Control Panel-"system and Security"-"Windows Firewall."

turning off unnecessary network ports can effectively protect network security, so do you know how to shut down these network ports ? We can enter the service and close the corresponding port in the following way. Turn off Port 7.9: Close Simple TCP/IP service and support the following TCP/IP services: Character generator, daytime, discard, Echo, and Quote of the day. Turn off 80: Turn off the WWW

First of all, to declare this function, personal feeling is not very useful, because most of the time we have to bring the system from the firewall closed. Like small series is certainly closed, because small weave sometimes in the local area network and other people connected to the net, if no matter the system with the firewall then I have no way to play. So the following is about the use of Win7 firewall settings to prevent access to the local port is not practical. 1 Open firewall fire has

There is a project that uses the PC104 board (PCM-3341), the Linux system. But at least 3 RS232 in the project, see Datasheet, enough. The board has 3 separate RS232 and a rs232/485 multiplexing port. But in the actual test use, encountered a problem. 1 and 2 can work (later found to be problematic, reading sensor data, reading is not complete), but 3 and 4 have appeared very strange phenomenon. The main performance is: 1. Can input output 2. Input and output rate is very slow 3. Found that

behavior occurs. So unloading load, all default, fault still. 5, installation version of the problem; Viewing the installation CD is a time-tested installation disk and should not be problematic. 6, the problem of the system; Can not see what other problems, is the system of the problem? But reloading the system can be too much trouble, or think of other ways to see if you can find the problem. Check the system log, this should be a better habit. After a careful look over the reinstall log
