Linux Driver Development IV (the serial port of hardware knowledge that must be understood) In the previous article, we understand the processor, memory, in this article Lao Xie want to chat with you in the actual project development process of the basic knowledge and role of the serial port.First, the introduction of the serial portIf you want to understand the definition of the serial

string line back. My program is Linux qtembedded. I have used several other methods to debug serial data sending. Here is a brief summary.1. Stand-alone. Use ln-s output/dev/ttysac2 to connect the serial port ttysac2 used in the program to a file. After writing the data, use xxd to open the file and check the hexadecimal output. The disadvantage is that the results are slow and the advantage is the simples

Linux lower port forwarding is generally implemented using iptables, and using Iptables can easily forward TCP and UDP ports from the firewall to the internal host. However, if you need to forward traffic from a private address to a machine that is not on your current network, you can try another application-tier port redirector, rinetd. RINETD is short and effic

the netstat command is a useful tool for monitoring TCP/IP networks. It displays the route table, the actual network connection, and the status information of each network interface device, here I only use some of these features. Common netstat parameters:-T,-u,-W, and-x indicate TCP, UDP, raw, and UNIX socket connections. -A flag will also display the socket waiting for connection (that is, in listening mode. -L display the listening (Listen)

1th step: If you want to restrict access to Linux via SSH IP, you can do the following: First: Modify/etc/hosts.deny, add Sshd:all in it, and note that you can't add the # number. Then: Modify:/etc/hosts.allow, in which the following settings are made: sshd:192.168.1.16 This setting only allows 192.168.1.16 IP to log on to the Linux machine via SSH. Of course, as a server, do not install the GNOME and K

Scenario Requirements:for large systems involving vertical cascading (such as Headquarters, sub-ministerial) or horizontal interconnection (interconnection with other systems at this level), It is often necessary to verify the opening of the relevant port when the system service is not deployed in case the port is opened on the firewall.

One or more mirror ports can be configured on all high-end models, most middle-end models, and some low-end vSwitch routers. it is a powerful tool for traffic analysis. However, there is no ready-made technology in Linux to implement the image Port. of course, I am not referring to Linux3x (x is a few, One or more mirror ports can be configured on all high-end mo
