It can forward commands from pnet to psrv and pass back the replies. prun starts the data taking, gets the data from the spectrometer, and passes it via a socket to the psrv program running on the file server. ... There is a psrv task for each prun task (one for each subband on a spectrometer box). prun starts psrv via xinetd by connecting to the well known port address. psrv accepts commands from pnet via prun. ...

multi-rsh is a perl script which runs the same command on multiple machines, in parallel, and provides reasonable, adjustable timeouts for those machines which fail to answer. Both standard output and standard error are returned through the same channel, and all output has the hostname prepended to each line. Multi-rsh must be run as root (remote jobs can be set to run as any user, see Options below). ... Neither form allows you to directly pass input to the remote programs. ...
