clearing TCP connection

[LEJARRE Patrick]

How to clear a TCP connection without reboot.
Context: License server isn't running anymore but the TCP port associated is still used ( LISTEN )
HP-UX 10.20 and 11.00

Hi,

First, use lsof to check for any processes still binding to the port. Terminate the process identified.

If there are no process binding to that LISTEN port, then use ndd (only applicable to HP-UX 11.00) to force close the connection (though not recommended) via tcp_discon and/or tcp_discon_by_addr. Details at:
