The domain configuration server (DCS) is a daemon process that runs on Sun servers that support remote dynamic reconfiguration (DR) clients. It is started by inetd(1M) when the first
DR request is received from a client connecting to the network service sun-dr. After the DCS accepts a DR request, it uses the libcfgadm(3LIB)
interface to execute the DR operation. After the operation is performed, the results are returned to the client.
The DCS listens on the network service labeled sun-dr. Its underlying protocol is TCP, and it is invoked as an inetd server using the TCP transport. The entries for the DCS in the /etc/inet/inetd.conf file are as follows:
sun-dr stream tcp wait root /usr/lib/dcs dcs
sun-dr stream tcp6 wait root /usr/lib/dcs dcs
These entries enable remote DR operations. Removing them does not negatively impact the server; however, all DR operations initiated from a remote host would fail.
