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.
