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

[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

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!

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

Reference:Https://wiki.openwrt.org/doc/recipes/relayclientThis method can implement relay APS without the need for AP (WDS) mode. After relaying, the LAN ports that are equivalent to the route and AP hotspots are routed in the same network segment as the ancestor. If you want to access the Luci of this route, set the computer's IP address manually, and the LAN IP for this route is in the same network segment.Get ready:Components that need to be instal
