As far as I know precision of cron is of the order of seconds, isn't it?

Thanks
I don't know the precision of cron, but even if it is to to miliseconds you have no guarantee, since you never know when exactly your processes are granted processor time. A lot will depend on other activities on the system.

in.rarpd

in.rarpd(1M)						  System Administration Commands					      in.rarpd(1M)

NAME

       in.rarpd, rarpd - DARPA Reverse Address Resolution Protocol server

SYNOPSIS

       /usr/sbin/in.rarpd [-d] -a

       /usr/sbin/in.rarpd [-d] device unit

DESCRIPTION

       in.rarpd  starts a daemon that responds to Reverse Address Resolution Protocol (RARP) requests. The daemon forks a copy of itself that runs
       in background. It must be run as root.

       RARP is used by machines at boot time to discover their Internet Protocol (IP) address. The booting machine provides its  Ethernet  address
       in  a  RARP  request  message.  Using the ethers and hosts databases, in.rarpd maps this Ethernet address into the corresponding IP address
       which it returns to the booting machine in an RARP reply message. The booting machine must be listed in	both  databases  for  in.rarpd	to
       locate its IP address. in.rarpd issues no reply when it fails to locate an IP address.

       in.rarpd uses the STREAMS-based Data Link Provider Interface (DLPI) message set to communicate directly with the datalink device driver.

OPTIONS

       The following options are supported:

       -a	Get the list of available network interfaces from IP using the SIOCGIFADDR ioctl and start a RARP daemon process on each interface
		returned.

       -d	Print assorted debugging messages while executing.

EXAMPLES

       Example 1: Starting An in.rarpd Daemon For Each Network Interface Name Returned From /dev/ip:

       The following command starts an in.rarpd for each network interface name returned from /dev/ip:

       example# /usr/sbin/in.rarpd -a

       Example 2: Starting An in.rarpd Daemon On The Device /dev/le With The Device Instance Number  0

       The following command starts one in.rarpd on the device /dev/le with the device instance number 0.

       example# /usr/sbin/in.rarpd le 0

       national, June 1984.

NOTES

       The in.rarpd service is managed by the service management facility, smf(5), under the service identifier:

       svc:/network/rarp

       Administrative  actions	on  this  service, such as enabling, disabling, or requesting restart, can be performed using svcadm(1M). The ser-
       vice's status can be queried using the svcs(1) command.
