Run a script at remote server without ssh password
Hello,
What I want to do is to run a file on remote server by running a script at localhost but script should not ask ssh password of my remote server when script is executed.
Scenario1:
To copy files from server2 to data server:
When I enter above code, it asks for my server2 ssh password
Scenario2:
I want to run a script existing in server1 and it will be run at server2
When I enter above code in terminal, it asks for my servers ssh password.
I want to run ssh or scp commands from a script via crontab, but don't know how the script will remember remote server's ssh password.
I tried different variations but no result.
How may I do this?
Thanks in advance
Boris

ssh-copy-id
SSH-COPY-ID(1) General Commands Manual SSH-COPY-ID(1)NAME
ssh-copy-id - install your public key in a remote machine's authorized_keys
SYNOPSIS
ssh-copy-id [-i [identity_file]] [user@]machine
DESCRIPTION
ssh-copy-id is a script that uses ssh to log into a remote machine (presumably using a login password, so password authentication should be
enabled, unless you've done some clever use of multiple identities)
It also changes the permissions of the remote user's home, ~/.ssh, and ~/.ssh/authorized_keys to remove group writability (which would oth-
erwise prevent you from logging in, if the remote sshd has StrictModes set in its configuration).
If the -i option is given then the identity file (defaults to ~/.ssh/id_rsa.pub) is used, regardless of whether there are any keys in your
ssh-agent. Otherwise, if this:
ssh-add -L
provides any output, it uses that in preference to the identity file.
If the -i option is used, or the ssh-add produced no output, then it uses the contents of the identity file. Once it has one or more fin-
gerprints (by whatever means) it uses ssh to append them to ~/.ssh/authorized_keys on the remote machine (creating the file, and directory,
if necessary)
