+ <p>Starts an Erlang node with name <c>Node</c> on host <c>Host</c> as

+
+ <p>Options <c>Username</c> and <c>Password</c> are used to log on to the
+ remote host <c>Host</c>. <c>Username</c>, if omitted, defaults to
+ the current username. <c>Password</c> is empty by default.</p>
+
+ <p>A list of functions specified in option <c>Startup</c> are
+ executed after startup of the node. Notice that all used modules
+ are to be present in the code path on <c>Host</c>.</p>
+
+ <p>The time-outs are applied as follows:</p>
+
+ <taglist>
+ <tag><c>BootTimeout</c></tag>
+ <item><p>The time to start the Erlang node, in seconds. Defaults to
+ 3 seconds. If the node is not pingable within this time, the result
+ <c>{error, boot_timeout, NodeName}</c> is returned.</p></item>
+ <tag><c>InitTimeout</c></tag>
+ <item><p>The time to wait for the node until it calls the internal
+ callback function informing master about a successful startup.
+ Defaults to 1 second. In case of a timed out message, the result
+ <c>{error, init_timeout, NodeName}</c> is returned.</p></item>
+ <tag><c>StartupTimeout</c></tag>
+ <item><p>The time to wait until the node stops to run
+ <c>StartupFunctions</c>. Defaults to 1 second. If this time-out
+ occurs, the result <c>{error, startup_timeout, NodeName}</c> is
+ returned.</p></item>
+ </taglist>
+
+ <p><em>Options:</em></p>
+
+ <taglist>
+ <tag><c>monitor_master</c></tag>
+ <item><p>Specifies if the slave node is to be stopped if the
+ master node stops. Defaults to <c>false</c>.</p></item>
+ <tag><c>kill_if_fail</c></tag>
+ <item><p>Specifies if the slave node is to be killed if a time-out
+ occurs during initialization or startup. Defaults to <c>true</c>.
+ Notice that the node can also be still alive it the boot time-out
+ occurred, but it is not killed in this case.</p></item>
+ <tag><c>erlang_flags</c></tag>
+ <item><p>Specifies which flags are added to the parameters of the
+ executable <c>erl</c>.</p></item>
+ <tag><c>env</c></tag>
