Prompts on Terminals
No. Prompt Description
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 off or some other problems 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
reestablishing 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.
