UPDATE_SLAVE(1M)         DOMAIN/IX SYS5          UPDATE_SLAVE(1M)



NAME
     update_slave - update auxiliary system administrator's nodes

USAGE
     update_slave //master_nodeid //slave_nodeid . . .
     update_slave //master_nodeid[/systype]
     //slave_nodeid[/systype] . . .

DESCRIPTION
     Update_slave is a DOMAIN/IX shell script which updates the
     /etc directories, as well as other system administrative
     information, on auxiliary system administrator's nodes.
     Master_nodeid is the node ID of the single master system
     administrator's node on the network.  Slave_nodeid is the
     node ID of any slave, or auxiliary, system administrator's
     node.  Multiple auxiliary nodes may be specified on the same
     command line.

     Because of the distributed nature of the DOMAIN/IX system,
     you may maintain only one master set of such files as
     /etc/passwd, /etc/passwd.map, and /etc/group per network, on
     the network's single master system administrator's node.
     Otherwise, the mapping between information in the DOMAIN
     registries and information in these files will not always be
     accurate.

     However, since two DOMAIN networks can be connected to
     operate as one internet, it may be necessary to have copies
     of the /etc files and directories on both rings, in case the
     connection fails.  In that case, the update_slave script is
     used to ensure that information in /etc on the slave
     administrator's node agrees with that in /etc on the master
     administrator's node.  You might also wish to have slave
     system administrator's nodes if you have a very large net-
     work.

     The update_slave script is normally run from cron, in a line
     of the following form.

     0 6 * * * //master_nodeid/etc/update_slave //master_nodeid //slave_nodeid

     It can also be run from a shell prompt, if necessary.

     It is possible that a master administrative node will run
     one systype of DOMAIN/IX, and a slave, another.  The second
     case of the command, under USAGE, is used in this case.  In
     the example that follows, the master node(//administrator)
     is running bsd4.2, and is updating a slave node (//auxili-
     ary) running sys5.
