Steps:
1. modify the configuration in the kernel:
Run the make menuconfig command to cancel the Console on jz47xx and compatible serial port options;

2. modify the configuration in rootfs:
Run the following command in the/etc/inittab File System:

1. Configure terminal simulation software parameters.
2. Connect one end of the rolover cable to the control port of the router.
3. Connect one end of the rolover cable to the conversion adapter from the RJ-45 to the DB-9.

You can configure a vro in the following ways:
1. Use the master Console port to connect to the terminal configuration.2. Connect a Modem to the telephone network at the AUX port and configure it at the remote end.3. You can configure telnet through virtual termianl on the TCP/IP network.4. You can download the configuration from the TFTP Server.5. You can use the network management workstation for configuration.

When we use routes, we often encounter different problems. How can we solve the configuration system faults? I believe this article will help us solve the problem when the system configuration fails.
1. Terminal troubleshooting without display
(1) fault
After the vro is powered on, no information is displayed on the configuration terminal.
(2) troubleshooting
Step 1: first, perform the following checks:
Whether the power supply system is normal.
Configure whether the port (console) cable

If the vro is powered on for the first time, the system automatically runs the Setup command to notify the user to configure the required parameters for the vro to start, including the vro host name, privileged user password, SNMP,

The most noteworthy among these applications is the text editor, which is usually the application that you need to run most on the remote console. By the way, jed is a particularly good remote text editor; its strong kernel may use vim. Most other Linux/UNIX editors are neither X-based nor extremely rough (or bloated, such as emacs ).

Just like the replacement of file names, the replacement of variable names is performed before the program is called. In the second example, the $ symbol is omitted. Therefore, shell simply passes the string to echo as a parameter. In variable replacement, the variable value replaces the variable name. For example, in $ ls $ LOOKUP/filename, use/usr/mydir/filename as the parameter to call ls. Environ
