NAME

       nuke - launch nuclear weapons at mapped USENET sites

SYNOPSIS

       /etc/nuke [-y yield] [-a height] [-hcm] sitename...

DESCRIPTION

       Nuke employs the `missile coordinate' fields in the USENET map database and Internet connections to a server interfaced with AUTOVON to lob
       nuclear weapons at other UNIX sites, specified by name.	The default warhead is a single 25KT groundburst tac nuke; options  support  other
       combinations of warhead size, type and deployment.

       The  -y	option specifies a yield.  The argument must be a number suffixed by K or M, for kiloton or megaton respectively.  Yield arguments
       above 255M are quietly ignored.

       The -a option specifies an air-burst height in meters.

       The -h option specifies thermonuclear (hydrogen) weapons.

       The -c option specifies cobalt-jacketed warheads for permanent site interdiction.

       The -m option, useful with multiple-site nuke calls, invokes code which optimizes delivery using MIRVed warheads to minimize launches.

       In accordance with the normal UNIX design philosophy nuke does not prevent you from nuking yourself.

FILES

       /usr/lib/maps/*		USENET map file database

BUGS

       If a target site has given only nearest-city coordinates in its map entry, incorrect targeting and significant  collateral  casualties  may
       result.

       Heavy use of nuke may cause EMP effects which interfere with Internet service.

NOTE

       This command is restricted to super-users only.

NAME

       parallel-nuke - kill a bunch of processes on a set of machines

SYNOPSIS

       parallel-nuke [OPTIONS] -h hosts.txt pattern

DESCRIPTION

       pssh provides a number of commands for executing against a group of computers, using SSH. It's most useful for operating on clusters of
       homogenously-configured hosts.

       The parallel-nuke command is useful when you want to kill a bunch of processes on a set of machines.

OPTIONS

       -h --hosts
	   hosts file (each line "host[:port] [user]")

       -l --user
	   username (OPTIONAL)

       -p --par
	   max number of parallel threads (OPTIONAL)

       -o --outdir
	   output directory for stdout files (OPTIONAL)

       -e --errdir
	   output directory for stderr files (OPTIONAL)

       -t --timeout
	   timeout (secs) (-1 = no timeout) per host (OPTIONAL)

       -O --options
	   SSH options (OPTIONAL)

       -v --verbose
	   turn on warning and diagnostic messages (OPTIONAL)

EXAMPLE

       For example, suppose you've got a bunch of java processes running on three nodes that you'd like to nuke (let's use the three machines from
       the pssh example). Here you would do the following:

	   # parallel-nuke -h ips.txt -l irb2 java
	   Success on 128.112.152.122:22
	   Success on 18.31.0.190:22
	   Success on 128.232.103.201:22

ENVIRONMENT

       All four programs take similar sets of options. All of these options can be set using the following environment variables:

       o   PSSH_HOSTS
       o   PSSH_USER
       o   PSSH_PAR
       o   PSSH_OUTDIR
       o   PSSH_VERBOSE
       o   PSSH_OPTIONS
