I presume you are doing this as root. You allow root to ssh onto all your servers ?
Using rudiC example. Just add & on the end and/or </dev/null
If you are running remote ssh commands on a list of servers, you have to add
</dev/null at the end or it will exit after the first one.
With just </dev/null it will run the command on each server in foreground one after another.
You can also add & to the end and it will execute the command in background on each server and return at once.
Test the script with the echo first and then remove, when you want to use it.

Hello all.
I have built a cluster of 9 Macs for computational chemistry and I need a shell script that I can use from one computer to all the rest to shutdown.
I have modified all of the Macs so that there is pass-wordless ssh. As well, I have modified each "visudo" file on each machine by... (1 Reply)

ssh-keysign
SSH-KEYSIGN(8) BSD System Manager's Manual SSH-KEYSIGN(8)NAME
ssh-keysign -- ssh helper program for hostbased authentication
SYNOPSIS
ssh-keysign
DESCRIPTION
ssh-keysign is used by ssh(1) to access the local host keys and generate the digital signature required during hostbased authentication with
SSH protocol version 2.
ssh-keysign is disabled by default and can only be enabled in the the global client configuration file /etc/ssh/ssh_config by setting
HostbasedAuthentication to ``yes''.
ssh-keysign is not intended to be invoked by the user, but from ssh(1). See ssh(1) and sshd(8) for more information about hostbased authen-
tication.
FILES
/etc/ssh/ssh_config
Controls whether ssh-keysign is enabled.
/etc/ssh/ssh_host_dsa_key, /etc/ssh/ssh_host_rsa_key
These files contain the private parts of the host keys used to generate the digital signature. They should be owned by root, read-
able only by root, and not accessible to others. Since they are readable only by root, ssh-keysign must be set-uid root if hostbased
authentication is used.
