I installed Putty on my local Windows machine A. I am connecting to remote linux server B from A. From B, I want to connect to multiple other remote machines C, D, E, F etc without entering password all the time.
Is there any way to achieve this ? I tried setting up SSH keys from A to B. But to login to multiple other hosts from B, do I need to set keys on every other hosts ?
ssh ssh-keygen

Yes, you need to add a private key(*) in your SSH config on host B, and the matching public key in the authorized_keys file on C,D,E,F.
(*) Which is best kept distinct from the one you use to login from A to B.

Yes you need to set up ssh-key authentication from Host B to all hosts. to connect from B to other hosts with out password. You can copy public key generated in B host to all other hosts in authorized_keys file
There is another method also using sshpass .
But it wont be secure format of using sshpass is as below:
sshpass -p "password" ssh username@hostname
