Maintaining the Router with FTP Server
Maintaining the router when it serves as the server
FTP (File Transfer Protocol) is an application layer protocol in the TCP/IP suite. It mainly transfers files
among remote hosts. Carried over TCP, it provides reliable and connection-oriented data transfer
service but does not provide access authorization and authentication mechanism.
The FTP service provided by the router is FTP Server, that is to say, the router serves as the FTP Server.
You can run FTP Client to log onto the router and access files on the router.
Install FTP Client before using FTP. No FTP Server is available with the MSR 50 series. You must install
one yourself. Take the FTP Client with Windows XP for example.
Step 1: Build hardware maintenance environment as follows:

Configure the IP addresses of the two sides to be in the same network. In this section, the PC server is
set to 192.168.0.1, and the router Ethernet interface connected to it (Ethernet interface 0/0 in this
example; so, any interface is OK) is set to 192.168.0.2. Both can use the
ping
command to check if the
connection is successful.
Step 2: Boot FTP service.
You can boot FTP service after configuring FTP server authentication and authorization. FTP server
supports multi-user access. The remote FTP user sends request to the FTP server, which then
