Hello experts,
i have to login to multiple servers using ssh and i wish to automate it,
after doing ssh,
it prompts - Are you sure you want to continue connecting (yes/no)? --> i need to give input as yes
then it prompts for password ----> i need to input my password then
and execute a command and log out.
Please let me know a way to automate it.
i have checked sshpass utility is not present in the server im working on. please suggest.
thanks

Generate SSH keys on the server that you have access to, add public key to the other servers ~/.ssh/authorized_keys
Then from the server that you have access to, run a command like this:
ssh user@other_server_1 command
Test with a few servers first, then add the public keys to the others.

yes...i understand but if you see i have few hundreds of server, to setup ssh across all is going to take a considerable time.#
the username/password im going to use to the servers is same.
Im not against ssh, please let me know if there is a way to speedup ssh setup in this case.

Using SSH keys will do just that for you.

Using passwords on a command line is a bad practice. Setup SSH keys and automation is easy just do:
ssh user@server command
There are some previously answered quesions about setting up SSH keys here at EE like this one for example:

Thanks for the reply Duncan.
I cant do it from command line, i have to execute the script from a server..it is because of security..access to these servers from my desktop is not allowed.
I checked your command from the server it says - Bad port 'w'.

Be reminded, if the SSH change, the command should be this, where 8888 is just example
port change
c:program fiies <x86>Puttyputty.exe -ssh yourogin@214.3..211283 -pw yourpassword -P 8888

putty.exe can run at command-line such as
c:program fiies <x86>Puttyputty.exe -ssh yourogin@214.3..211283 -pw yourpassword
You can make easy batch script to login all server automatically
