ssh via rsh and feed of local file via cat command 1

[babcia01]

Hi
Would anyone know how to accomplish via remote ssh same capabilities as can be accomplished via rsh command as noted under 1)?

The 1-st rsh based command works. The local filex is read into rsh chpasswd command on the remote server.

1) cat filex| rsh serverx chpasswd

The below 2-nd command does not work. I want to eliminate placing filex on each remote server where I want to run the chpasswd due to its sensitive nature even though I will delete it after I am done.

2) cat filex |/usr/local/bin/ssh -n -q -o "StrictHostKeyChecking no" -o "BatchMode yes" root@serverx chpasswd

Nice Question babcia01

What is the error you get when you run command no 2?

dsh (Distributed Shell) is a very nice tool for your case!

If you want to run commands on multiple hosts, first include the hosts in a file (newline-spearated)

Then do the following to that file (supposed its name is hello)

# export WCOLL=/hello
# dsh –r ssh 'df –k;ls'

This will run in all hosts that are located in the hello file! Very nice command!

But i'm not sure how this would be used in your case to be honest!

You can do this as well

# for i in host1 host2 host3 host4;
do ssh $i ‘df -k; ls’; done
