What you need is possible.

I wrote a wrapper for SSH that will run commands on other servers in parallel. It accepts a file, which contains host names.

I don't know about ping'ing 700 in under a second, but in theory it should work. But come to think of it, you wouldn't run the ping command on remote hosts by running commands on the remote hosts.

Anyway, here is an idea:

Code:
root@ms:/>gdsh
   Usage: [[-s working_col_file|OS_name] | -w nodename{,nodename}] -c command

   Required Parameters:
         -s or -w and -c

   Optional Parameters:
         [-n]
         [-d] [-h] [-n] [-T] [-v]

   Where:
         -C
            Collapses output. Used with dshbak.
         -c specifies the command to run
            Required.
         -n
            No Parallel mode. By default the command is run on every node at the same time.
         -s
            Specify a working collective file OR specify an OS name. Use uname -s to specify
             a working collective file with that postfix. ie. /.gwcoll.AIX.
         -w nodename{,nodename}
            Default: ALL nodes

   Options that affect only how the script runs:
         -d
            Enable debug mode. Variable contents will be printed. May be specified more than once.
         -h
            Prints this help screen.
         -q
            quiet. Limits output to the essentials.
         -T
            Testing mode. NO actual work will be done.
         -v
            Verbose mode. May be specified more than once.

   Notes:
         One of -s or -w is required.
         Piping the output to dshbak -c will group like results together.
         Use -C with dshbak, or you will get no output.
         -c must be the last flag on the command line.

   Example execution statements:
         gdsh -s /.gwcoll.AIX -c date
         gdsh -s AIX -c date
         gdsh -C -s AIX -c date | dshbak -c
         gdsh -s all.Linux_HP-UX -c date
         gdsh -C -w unxn_sw,wpgux005 -c "date" | dshbak -c

Example run:
Code:
gdsh -C -s HP-UX -c "/usr/bin/date" | dshbak -c

wpgux001_sw, wpgux003_sw, wpgux004_sw, wpgux005_sw, wpgux006_sw, wpgux007_sw, wpgux010_sw, wpgux011_sw

nodename(4)							   File Formats 						       nodename(4)

NAME
nodename - local source for system name SYNOPSIS
/etc/nodename DESCRIPTION
When a machine is standalone or its IP address is configured locally, the /etc/nodename file contains the system name. By convention, the system name is the same as the hostname associated with the IP address of the primary network interface, for example, hostname.hme0. If the machine's network configuration is delivered by the RPC bootparams protocol, the /etc/nodename file is not used, as the system name is delivered by the remote service. Given a system name value, regardless of source, the uname utility invoked with the -S option is used to set the system name of the running system. If the machine's network configuration is delivered by the DHCP protocol, the /etc/nodename file is used only if the DHCP server does not provide a value for the Hostname option (DHCP standard option code 12). A system name configured in /etc/nodename should be unique within the system's name service domain in order to ensure that any network ser- vices provided by the system will operate correctly. Given a system name value, regardless of source, the uname utility invoked with the -S option is used to set the system name of the running system. EXAMPLES
Example 1: Syntax The syntax for nodename consists of a single line containing the system's name. For example, for a system named myhost: myhost ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ SEE ALSO
nis+(1), uname(1), named(1M), ypbind(1M), attributes(5) NOTES
The nodename file is modified by Solaris installation and de-installation scripts. SunOS 5.10 9 Feb 2004 nodename(4)
