WARNING: The tcp_close_wait_interval is set to 240000 milliseconds (240 seconds).
This value should be reduced to allow for more simultaneous connections to the
server. A line similar to the following should be added to the
/etc/init.d/inetinit file:
ndd -set /dev/tcp tcp_time_wait_interval 30000
NOTICE : The tcp_conn_req_max_q value is currently 128, which will limit the value
of listen backlog which can be configured. It can be raised by adding to
/etc/init.d/inetinit, after any adb command, a line similar to:
ndd -set /dev/tcp tcp_conn_req_max_q 1024
NOTICE : The tcp_keepalive_interval is set to 7200000 milliseconds (120 minutes).
This may cause temporary server congestion from lost client connections.
NOTICE : The tcp_keepalive_interval can be reduced by adding the following line to
/etc/init.d/inetinit:
ndd -set /dev/tcp tcp_keepalive_interval 600000
NOTICE : The NDD tcp_rexmit_interval_initial is currently set to 3000 milliseconds
(3 seconds). This may cause packet loss for clients on Solaris 2.5.1 due to a bug
in that version of Solaris. If the clients are not using Solaris 2.5.1, no
problems should occur.
NOTICE : If the directory is service is intended only for LAN or private
high-speed WAN environment, this interval can be reduced by adding to
/etc/init.d/inetinit:
ndd -set /dev/tcp tcp_rexmit_interval_initial 500
NOTICE : The NDD tcp_smallest_anon_port is currently 32768. This allows a maximum
of 32768 simultaneous connections. More ports can be made available by adding a
line to /etc/init.d/inetinit:
