4 Terminate all the ttyd processes corresponding to a specified router IP address.
From the process management submenu, select option 4 to display the following
information:
Enter router IP address:
Here, you can terminate all the ttyd processes associated with a router by entering
the corresponding router IP address. This makes operation more convenient
because you can terminate multiple processes at one time.
5 Terminate the ttyd process corresponding to a specified terminal.
From the process management submenu, select option 5 to display the following
information:
Terminal in use: ttyp55
Enter the terminal name to terminate (ttypxx):
Here, you can terminate the ttyd process associated with a terminal by entering
the corresponding terminal name. This makes operation more convenient because
you do not need to query the number of the process before terminating it.
6 Set the log output levels.
When a system fault occurs, you may need to determine the cause by viewing the
system logs. The system creates a log file for each main ttyd process and child
process. The output directory of the ttyd debugging file(s) is /var/ttydlist by default.
The debugging file of the main ttyd process is named in the format of
ttydxxxx.log, where xxxx is the number for 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 corresponding to the child process.
There are four log output levels:
Level 0. At this level, only error information is output.
■
Level 1. At this level, alarm information is output besides error information.
■
Level 2. At this level, prompt information is output besides error and alarm
■
information.
Level 3. At this level, besides error, alarm, and prompt information, all the data
■
read from and written to sockets and pseudo-terminals (PTYs) are output in the
character format and in the hexadecimal format respectively.
The default log output level is level 0; that is, only error information will be output.
To view more detailed log information, you need to adjust the log output levels.
After the log output level is set to a higher one, the debugging information that is
displayed at all the lower levels will also be output.
From the process management submenu, select option 6 to display the following
information:
Enter the terminal name corresponding to the process or child process.
