I have a problem with public and private key authentication. I do this steps and then, public-key based doesn't work. 1- generate a pair of private and public key (RSA) using the following command:
Generating public/private rsa key pair. Enter file in which to save the key (/home/rc_ss/.ssh/id_rsa): Created directory '/home/rc_ss/.ssh'. Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /home/rc_ss/.ssh/id_rsa. Your public key has been saved in /home/rc_ss/.ssh/id_rsa.pub. The key fingerprint is: ac:fd:d1:2e:e5:1e:db:87:98:77:9e:14:62:db:97:f0 rc_ss@rc_ss-network The key's randomart image is: +--[ RSA 2048]----+ | | | | | | | . | | S + . | | o .o * o| | . . .oo+ E.| | ..o+++ =| | .o+..=.| +-----------------+
2- copy it through network with ssh-copy-id as follows
rc_ss@rc_ss-network:~$ ssh-copy-id -i .ssh/id_rsa.pub email@example.com The authenticity of host '192.168.2.100 (192.168.2.100)' can't be established. ECDSA key fingerprint is 33:67:e0:02:b1:10:46:76:78:6b:1f:e2:55:9b:6a:a8. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added '192.168.2.100' (ECDSA) to the list of known hosts. firstname.lastname@example.org's password: Now try logging into the machine, with "ssh 'email@example.com'", and check in: ~/.ssh/authorized_keys to make sure we haven't added extra keys that you weren't expecting.
3- then, I want to get connected to server ssh without password, and deal with following:
rc_ss@rc_ss-network:~$ ssh firstname.lastname@example.org email@example.com's password:
Which means the password required yet. Can anybody help me? Appreciate it.
cat /root/.ssh/authorized_keyson the target machine, do you see the public key from the original machine?
