.SH SYNOPSIS
.B smsd
.br
For the server to be able to function properly, if must be run as root
and root must have access to the tables through RTI Ingres.
.PP
+It is possible to shutdown the database side of the server when it is
+necessary to lock out clients. In this state the server will only
+respond to noop and motd requests. When the file
+.B /etc/smsdown
+exists, the server will close the database the next time there are no
+clients using it. To force the server to close down the database as
+soon as any active operation is finished, send it a USR1 signal. The
+first time a new client connects after the
+.B /etc/smsdown
+file is removed, the database will be re-opened. To force an
+immediate reopening, send the server a USR2 signal. The contents of
+the
+.B /etc/smsdown
+file are returned as the SMS motd.
