#
# BackupPC_serverMesg: Send one or more commands to the BackupPC server.
#
# DESCRIPTION
# As of v1.5.0 the BackupPC server communicates via a unix or internet
# domain socket. Every message is protected with an MD5 digest, based
# on a shared secret, a sequence number, and a per-connection unique
# key. This minimizes the risk of an attacked issuing fake commands
# to the BackupPC server.
#
# Previously, telnet could be used to talk to the BackupPC server.
# As of v1.5.0 that is no longer possible.
#
# This script replaces telnet as a mechanism for sending BackupPC
# messages. Usage:
#
# BackupPC_serverMesg mesg
#
# Example:
# BackupPC_serverMesg status info
