2. The inittab system file configuration is correct.

For a dumb terminal, check whether the pseudo terminal is activated
A dumb terminal is a pseudo terminal that does not push the login interface.
Check whether the banking service process has activated the pseudo terminal. If not, activate it. If yes,
see "View the debugging information of the router and ttyd program of the server"
for more information.
View the debugging information of the router and ttyd program of the server
A debugging file is created for each main ttyd process and child process. By default, the destination
directory of the ttyd debugging files is /var/ttydlist. You can change this directory in the configuration
file ttyd.conf. The debugging file of the main ttyd process is named in the format of ttydxxxx.log, where
xxxx is the number of the listening port of the main process. The debugging file of a child process is
named in the format of ttypxx.log, where ttypxx is the name of the ttyp device for the child process.
The following analyses the common ttyd debugging information and provides some solutions.
1. authentication 1.1.92.52 failed.
Cause: The ttyd configuration file contains no configuration for the router. Solution: Configure the
IP address of the router in the ttyd configuration file, and then press <Enter> on the terminal.
2. Fail: Too many tcp links
Cause: Too many TCP connections have been established on the Unix server so that new TCP
connection requests cannot be accepted.
3. Fail: authenticate <10.110.96.44 6> fail, no such termNo in config file
Cause: The TTY number is not configured in the configuration file.
4. Fail: authenticate <10.110.96.44 6> fail, no such ip in config file
Cause: The IP address of the router, 10.110.96.44, is not configured in the configuration file.
5. Fail: connection closed by peer
Cause: The TCP connection has been closed by the router.
6. Fail: the swap is not enough to store the data , so some data is discarded
Cause: Data from the router is not written into the PTY device (pseudo terminal), making the buffer
full and subsequent data discarded. Typically, this is because the PTY device is not operating
normally.
7. Fail:fail to write data into screen
Cause: Data on the screen cannot be saved.
8. Fail:fail to recv data from socket
Cause: Failed to read user data from the socket.
9. Fail:fail to write data into pty
Cause: Failed to write data to the PTY device.
10. Fail:fail to read pty
Cause: Failed to read data from the PTY device.
11. Fail:fail to write data into socket
Cause: Failed to write data to the socket.
12. Fail:child process exit for out of time range
