NSA HTTP Components

Chapter6

Startup Script

The /sbin/init.d/nsahttp file is the startup script used to activate NSA HTTP at system

startup time. The system will activate NSA HTTP at system startup time if the

NSAHTTP_ENABLE flag is set to 1 in the NSA HTTP configuration file

(/etc/rc.config.d/nsahttpconf).

NOTE Do not modify the /sbin/init.d/nsahttp script file. This file is delivered with

the product and may be replaced in future product releases.

DLKM

NSA HTTP includes a DLKM, nsamod. The nsamod DLKM is used to spawn an NSA HTTP

service daemon, nsad. An nsad daemon is activated for every socket listening on the TCP port

registered with NSA HTTP. If logging is enabled, nsad logs HTTP access events to the log file,

which by default is /var/nsa/nsahttp_log.pid where pid corresponds to the process ID of

the nsad process. The nsad kernel daemon is also used to establish TCP connections for NSA

HTTP registered TCP ports and servicing cache requests.
