Solaris ndd command

The ndd command of solaris-general Linux technology-Linux technology and application information. The following is a detailed description. After a client program is running for a period of time, a large number of CLOSE_WAIT statuses appear on the tcp link, resulting in a later link failure.
The following is a link to the CLOSE_WAIT status through the ndd command.
1. First, su gets the root permission.
2. Run the following command: ndd/dev/tcp tcp_status | grep CLOSE_WAIT
You can use this command to locate these statuses, or write the information to the log file by writing scripts to add write time and other parameters.
Next, we want to set a life-saving timer for the solaris System to close these useless links as soon as possible. However, the three parameters set for the active timer are not found yet. I forgot to inform anyone. Thank you first. Our machine is solaris 9
