INFO PROCESS Command for TCP6SAM
Host Name
is the host on which the NonStop TCP/IPv6 subsystem is running.
Program Filename
is the name of the file being executed for this process.
Debug
is the current setting (ON or OFF) of the DEBUG attribute. Debug is used by HP
support and development personnel.
Full Dump
is the current setting (ON or OFF) of the FULLDUMP attribute.
All Nets Are Local
The default is ON. ON causes TCP to use the interface MTU as a base for
determining the TCP Maximum Segment Size (MSS) for each non-local TCP
connection. A non-local TCP connection is one that goes to another network (not
just another subnetwork).
If ALLNETSARELOCAL is OFF, TCP conforms to RFC-specified behavior and use
512 bytes as the default MSS for non-local segments. For example, for Ethernet,
when ALLNETSARELOCAL is ON, the non-local MSS is 1460; setting
ALLNETSARELOCAL to ON can improve performance.
TCP Compat 42
is the flag that sets the NonStop TCP/IPv6 subsystem compatible with BSD4.2
versions:
•
The default value of this flag is ON.
•
If the flag is ON, then the original ACK minus 1 is sent in the keepalive packet;
if the flag is OFF, the original ACK is sent in the keepalive packet.
EXPAND Security
is not supported NonStop TCP/IPv6.
TCP Path MTU
is ON to cause TCP to use PATH MTU discovery on all TCP-type sockets
(SOCK_STREAM) unless disabled by the SETSOCKOPT for SO_PMTU. The
default for this option is OFF.
TCP Time Wait
is the amount of time in seconds that a TCP connection remains in the TIME_WAIT
state. The default is 60 seconds. The range is 1 to 120.
