The syslog-ng 3.0 Administrator Guide

Solaris uses its STREAMS framework to send messages to the syslogd process. Solaris 2.5.1 and above uses an IPC called door in addition to STREAMS, to confirm the delivery of a message. The syslog-ng application supports the IPC mechanism via the door() option (see below).

	Note
	The sun-streams() driver must be enabled when the syslog-ng application is compiled (see ./configure --help). The pre-compiled binaries of syslog-ng Open Source Edition purchased from BalaBit and syslog-ng Premium Edition have this option enabled.

The sun-streams() driver has a single required argument specifying the STREAMS device to open, and the door() option. For the list of available optional parameters, see Section 8.1.5, “sun-streams() driver”.

Declaration:
        sun-streams(name_of_the_streams_device door(filename_of_the_door));

	Example 3.12. Using the sun-streams() driver
	source s_stream { sun-streams("/dev/log" door("/etc/.syslog_door")); };
