Prompts on terminals

1

(TTY tty-number: vty-number starting connect to server fail!)

Creating a socket failed because, for example, no WAN IP address is configured on the router.

2

(TTY tty-number: vty-number fail to connect server-name!)

The router failed to establish a TCP connection to the Unix server because, for example, the Unix server is turned on but ttyd is not running.

3

(TTY tty-number: vty-number authentication failed or server-name no response)

The corresponding entries in the ttyd configuration file of the Unix server may be wrong, or the ttyd listening port on the Unix server and the application port on the router are different.

4

(TTY tty-number: vty-number peer socket close, fail to connect server-name!)

The TCP connection established between the Unix server and the router is down. This may occur when you close ttyd on the Unix server or turn off the Unix server.

5

(TTY tty-number: vty-number connecting with server-name...)

Normally, the router should be able to establish a TCP connection to the Unix server quickly. If the system prompts that the connection is still not established after a long time, the Unix server may be offline or some other problem may have occurred. Press a key on the terminal to initiate a new connection.

6

(TTY tty-number: vty-number success to connect with server-name)

A TCP connection is established between the router and the Unix server.

7

(TTY tty-number: vty-number link error with server-name while sending)

The status of the socket on the router changes when the router is establishing a TCP connection or sending data to the Unix server.

9

(TTY tty-number:%d break and reconnect with server-name)

The router just tore down a TCP connection and is re-establishing another TCP connection to the Unix server. This message appears when a terminal user presses the terminal reset hotkey.

10

(Out of time range, access forbidden!)

When terminal access periods are configured in the ttyd configuration file on the Unix server, this message appears if a terminal tries to access the Unix server during forbidden periods.

11

(authentication failed, fail to open pty device!)

Authentication of a terminal failed. The corresponding pseudo terminal on the Unix server cannot be opened.

12

(authentication failed, too many tcp links!)

Authentication of a terminal failed. The TCP connection number established by the ttyd program on the Unix server has reached the upper limit.

13

(authentication failed, invalid IP address!)

The source IP address of the TCP connection corresponding to the terminal is not consistent with the IP address configured in the ttyd configuration file on the Unix server.

14

(authentication failed, invalid TTY No.!)

Authentication of a terminal failed. The terminal number is not identical to that configured in the ttyd configuration file on the Unix server.

15

(authentication failed, unknown error!)

Authentication of a terminal failed. An unknown error occurred.
