The LMI (Local management interface, locally Management Interface) is the signaling standard between the CPE device (router) and the frame switch, adding extensions to the Frame Relay protocol for managing complex interconnection networks. The main Frame Relay LMI extension includes global addressing, virtual circuit state messages, and multicast.
Note: There are in fact 3 LMI criteria. In addition to the C

Configure DHCP in the route. This is the skill that the network administrator should master. In addition, we should know about DHCP relay during the configuration process. This article mainly introduces how to use a vrodhcp to build DHCP. After reading the specific operation steps, I believe you will understand it.
There are many ways to use a DHCP server. Here I will introduce how to use a vro as a DHCP server.

After installing Darwin streaming Server, you can use VLC to play streaming media files through the RTSP protocol. But now I have a need to send a DSS (assumed to be a machine) on the media file to another DSS (assuming B machine) on the client VLC by accessing the B machine to play the media files of a machine, that is, using B machine as a forwarding server. I found a lot of articles on the internet about configuring DSS, all of which are about how to install and configure playlists, not how t
We all know that some of the tp-link or D-Link router has a wireless relay problem, the normal router does not have a relay function can be used by their own brush system to make the router has wireless relay function, but this wireless relay function may be less stable, There is a problem with long-time connections to

1. What is mail relay and why should it be prevented from being abused?
Once a qmail server is set up, the server will have one or more domain names (which should appear in local or viritualdomains files), and QMAIL-SMTPD will listen for Port 25th and wait for a remote request to send mail. Other mail servers on the network, or MUA (mail User Age
Relay means that the server accepts the client's SMTP request and forwards the messages sent by the client to a third party. QMail control relay is very simple, as long as the client access to the SMTP process environment variable contains (relayclient= "") to allow relay, or reject.
