change password for multiple host
1-How can i change root password of 5 Fedora 11 machines (server1 server2 server3 server4 server5) with a single script ,
for example make password : 123456

NB. from server1 i can via ssh connect to the others machines without a password

Please help.

Maybe this can help:

Code:
man chpasswd

i.e.

Code:
for SERVER in server1 server2 etc; do
  ssh $SERVER 'echo "root:123456" | chpasswd'
done

chpasswd is available on RHEL and CentOS, so I imagine on Fedora too.

is there any other way that server1 will copy /etc/password and shadow file to other server via scp , without to apply the password on every machine ?

Are you sure that's such a good idea?

You want to change the root password on a handful of servers. Is that so complicated?

Reading your original post again, I may have mis-interpreted this at the time:

The root password has absolutely nothing to do with connecting to other machines via ssh.
