Hi,

First create a ssh password less environment then using a for loop you can run commands remotely.

There are different options. But you have to provide the passwd somehow.

1. Setup a password less ssh enviroment.Then you can create a script to check all the systems hostname.No passwd need to be provided.

2. If you are not setting up passwdless ssh,
still you can run the same script but it asks for the passwd for each time and you have to provide one by one, which is horrible for 257 servers.

3. You can create an expect script by providing each passwd.

Better and nice option is passwdless ssh.
