BKJIA is just as important as monitoring network traffic and protecting data and computers. Understanding the most basic network fault diagnosis and troubleshooting skills helps you save time and costs. Each Linux release comes with a large number of command line tools to help you diagnose network problems. In addition

gw1, p2 communicates with the outside world through gw2. The constraint is that your machine only has one Nic eth0. What should I do? You can use iptables to mark packets P1 and P2, and then use ip rule to set a policy route. In addition, you can use setsockopt directly in P1 and P2 applications to set ipmark, iptables is not required. However, this is all outdated.

or UDP 　　 In the early days, Sun designed NFS v2 to only use the UDP protocol, mainly because of the influence of the memory, network speed, and CPU of the machines at that time, and had to choose a method with a lighter burden on the machines. In NFS v3, Sun chose the TCP protocol as the default transmission mode. In Linux, UDP is the default protocol. As a server, there is no choice. However, as a client

One day a suse Linux 9.1 DHCP server was deployed on the network. DHCP is the Dynamic Host Configuration Protocol, which is used to automatically provide computers with IP addresses, subnet masks, and routing information. The software is simple to install on both the server and the client. But the clients on the network (using the operating system: Mandrake

Network hardwareLinux can use any network hardware that has a driver. Linux drivers are compiled into the kernel individually or as loadable modules. The Linux kernel supports many popular NICs by default. When selecting network hardware, it is best to always use the devices
