HP UX Internet and Networking Software manual Querytnservertrace, Keepaliveinterval

Administration Commands

query_tn_server_trace

Send Telnet NOP messages.

TM

Send Telnet DO TIMING-MARK messages.

keepalive_interval

Interval (in seconds) between consecutive keep-alive messages. The interval should be long enough to minimize network traffic, especially if there are typically many idle client connections. The shorter the keep- alive interval, the quicker failures are detected, but the more network traffic is generated. If the keep-alive interval is too short and there are many clients, this traffic can be significant.

Because of the way TCP/IP operates, the keepalive interval that you configure is not the exact time that it will take for the server to recognize that a client has disappeared. The configured interval is the minimum time in which a client could be timed out. The maximum is approximately twice the configured timeout, plus a few extra minutes (the exact number depends on how TCP/IP is configured).
