NAME

     dhisd -- Dynamic Host Information System server.

SYNOPSIS

     dhisd [-D] [-p port] [-d database] [-s services] [-l logfile] [-P pidfile]

DESCRIPTION

     DHIS is a client-server architecture meant to update databases for systems which are assigned a dynamic IP[v4] address.

     By the means of a DHIS client a host which is assigned a dynamic IP address (either from its ISP or from DHCP) is able to communicate with a
     DHIS server in order to advertise its newly acquired IP address.

     DHIS comprises a UDP based protocol to achieve this purpose.

     A DHIS client has a unique identification number and a set of authentication keys, runs in background, and attempts to reach its server.

     The DHIS server (permanently online) listens to UDP messages from its clients and authenticates these against its knowledge of keys. When
     authentication is successful the DHIS server updates one or more databases with the newly received IP address for the given client.

     The server then keeps sending, every period of time, check requests to each of its connected clients. These need to be acknowledged. If not
     the server will consider, on an individual basis, that the client has disconnected and will again update the databases to an offline state.

     Alternativelly the server may receive an OFFLINE_REQ packet from the client, in which case the DNS record is updated at once and the online
     state droped.

OPTIONS

     -D      Increase debug level.

     -p port
	     Specify port to listen on. If not specified, the default is port 58800.

     -d database
	     Use an alternative database file instead of /etc/dhis-server/dhis.db.

     -s services
	     Use an alternative database file instead of /etc/dhis-server/services.db.

     -l logfile
	     Use an alternative log file instead of /var/log/dhisd.log.

     -P pidfile
	     Use an alternative PID file instead of /var/run/dhisd.pid.

FILES

     /etc/dhis-server/dhis.db
	     DHIS client database.  Contains the credentials of clients.

     /etc/dhis-server/services.db
	     DHIS service database.  Contains a list of services and the location of the corresponding DHIS engine plugins.

BOOTPC(8)                                                     Debian GNU/Linux Manual                                                    BOOTPC(8)

NAME

       bootpc - bootp client

SYNOPSIS

       bootpc  [--bootfile  file]  [--dev  device]  [--verbose]  [--debug] [--server addr] [--hwaddr addr] [--returniffail] [--waitformore length]
       [--in2host addr] [--serverbcast] [--help]

DESCRIPTION

       This manual page documents briefly the bootpc command.  This manual page was written for the Debian GNU/Linux distribution (but may be used
       by others), because the original program does not have a manual page.

       bootpc is a boot protocol client used to grab the machine's IP address, set up DNS nameservers and other useful information.

OPTIONS

       --bootfile file
              Tell the server to use file as the boot file.

       --dev device
              Use device to communicate with the server.

       --verbose
              Be verbose.

       --debug
              Produce debugging output.

       --server addr
              Use the IP address addr to communicate with the server.

       --hwaddr addr
              Use addr as our hardware address rather than what the operating system gives us.

       --returniffail
              Terminate the program if a failure occurs.  By default bootpc will ask the user to press a key if the request did not succeed.

       --waitformore length
              Wait for more responses when one is received.  bootpc will wait for at most length seconds.  This is probably only useful for debug-
              ging.

       --in2host addr
              Takes an address and returns useful bits of the name after lookup, this was a separate program, but it is more compact to have  both
              together.

       --serverbcast
              Tell the server to send back a broadcast reply.  This is necessary on Linux 2.1 and 2.2.

       --help Display the usage of bootpc.
