Today, many files similar to hostname-relay-bin.0000 * are found in the mysql data directory of the local machine, which usually exists on the mysqlslave instance. The main purpose is to record the master-slave synchronization information, which will be automatically deleted under normal circumstances. The local machine has not been configured with master or slave, and its source is really unclear. Since it is used on slave Today, many files similar

[Cisco] DHCP relay, layer-3 Switch VLAN Routing PracticeThe experiment topology uses the GNS3 0.8.6 simulator to build a DHCP server using Red Hat 6.5. The experiment requires configuring a layer-3 Switch VLAN routing so that VLAN10 and VLAN20 members can access each other. Performs DHCP relay for layer-3 switches so that VLAN10 and VLAN20 members can obtain IP addresses through the DHCP server. Tutorial pr

Recently to use nat123 software, using the premise is fixed local IP, so I use this router to relay a primary router, and build a LAN. Router A uses the Tp-link router, and Router B uses the Bl-link router. Take the dial-up access network as an example, let me share my configuration process below.Step one, no line by relayRouter a(tp-link) Router a(tp-link) as the primary router, according to the instructions to complete the configuration, no special

Open relay are generally not open on many servers However, some servers support open. But the above services are based on the hardware environment! I think the people think, I thought of a way to use virtual relay! Intercepts the string that the user will send at the end of the @, spelling it into a mailserver, The mailserver that the sender is sending is the mailserver I intercepted. In this way, Mailsmtps

I. Overview: The second layer of many experiments with GNS can not be simulated, IOU most of the only command can not see the effect, very easy to have the opportunity to log into the rack to do the experiment, did the DHCP snooping experiment, found Cisco router if as a DHCP server, must be configured IPDHCP relay information Trusted, otherwise the client will not be able to obtain the IP address, if you want the DHCP server to use Windows 2003, the

This section focuses on the concept, analysis, and implementation of DHCP relaying. In some cases, we need to automatically configure IP addresses, gateways, and other network information for clients that are not on the same network segment, and the default DHCP does not seem to achieve this directly, so we need to use a small program, the DHCP Relay agent. It is designed to provide a bridge between a DHCP server and a DHCP client that is not on the

Along with the gradual enlargement of the LAN scale, a network is divided into several different subnets, in order to realize the individualized management requirement according to the work requirements of different subnets. Considering that larger LANs typically use a DHCP server to assign IP addresses to each workstation, but once the LAN is divided into multiple subnets, do we have to create a DHCP server in each of the different subnets to provide IP address assignment services for workstati

Optical Fiber Transmission Distance exceeds 12 thousand km without relay Optical Fiber communication (fiber-optic communication) refers to the use of optical and optical Fiber (optical fiber) to transmit information, is a type of wired communication. The optical fiber can not only transmit analog and digital signals, but also meet the needs of video transmission. The data transmission rate of a single optical fiber can reach several Gbps, without a r

Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. I implemented it in a virtual machine environment. Generally, when a virtual machine is opened, it will slow down. We only use one 2003 Server for customer service machine verification, during verification, yo

Mail and email service (III): POP3 authentication mechanism and relay rules We use Mago's "Create an existing Mail System based on the virtual user's mail system architecture" to implement the POP3 authentication mechanism. If you do not have an email service system that can be used, you can follow the instructions provided by magio and proceed step by step. I believe you can do this. Enter the subject: POP3 authentication mechanism: 1. Create a CA Se

tplink Router 740n relay Setup method Here is a note: You must know the upper-level router's WiFi password and DNS server address. The successful records are as follows: The first step: first use the mobile phone to connect the superior router WiFi, get the IP address. For example: 192.168.0.103. Remember it first! Landing their own Tp-link wr740n wireless router, click the "Network Parameters"->"lan Port Settings", the LAN address set to 192.168.
