in thread [OT] A New Everything ?

Aldebaran is telling you that /home/fred does not exist.

That did throw me for my first of many "what the heck" moments. I soon created barney with the right command. I misunderstood a good handful of things in trying to get barney's ssh squared away, so I moved on to wilma. I needed to have directories and files set with proper ownership, e.g. wilma needs to own .ssh . One thing I was reading wrong was that I thought authorized_keys was a directory that contained files. Not so.

We're getting deep down into the weeds of this thread, and I've gotten a lot of great help on a nebulus and moving target, but we get fewer eyes down here, and I don't want to punish the people who are helping me by keeping it going forever. I'm close with wilma and I think I'm gonna get over on betty. Here's my latest attempt with wilma:

root@third:/home/wilma/.ssh/authorized_keys# mv id_rsa.pub ../ root@third:/home/wilma/.ssh/authorized_keys# cd .. root@third:/home/wilma/.ssh# ls authorized_keys id_rsa.pub root@third:/home/wilma/.ssh# rmdir authorized_keys/ root@third:/home/wilma/.ssh# echo id_rsa.pub >>authorized_keys -rw-r--r-- 1 wilma wilma 419 Sep 25 02:46 id_rsa.pub root@third:/home/wilma/.ssh# chown wilma:wilma authorized_keys root@third:/home/wilma/.ssh# cd .. root@third:/home/wilma# chown wilma:wilma .ssh root@third:/home/wilma# chmod 700 .ssh root@third:/home/wilma# ls -la ... drwx------ 2 wilma wilma 4096 Sep 25 06:16 .ssh ... root@third:/home/wilma# cd .ssh/ root@third:/home/wilma/.ssh# chmod 600 authorized_keys root@third:/home/wilma/.ssh# exit logout Connection to 143.110.153.42 closed. $ ssh wilma@143.110.153.42 wilma@143.110.153.42: Permission denied (publickey). $ ssh -v wilma@143.110.153.42 OpenSSH_7.6p1 Ubuntu-4ubuntu0.3, OpenSSL 1.0.2n 7 Dec 2017 debug1: Reading configuration data /etc/ssh/ssh_config debug1: /etc/ssh/ssh_config line 19: Applying options for * debug1: Connecting to 143.110.153.42 [143.110.153.42] port 22. debug1: Connection established. debug1: identity file /home/hogan/.ssh/id_rsa type 0 debug1: key_load_public: No such file or directory debug1: identity file /home/hogan/.ssh/id_rsa-cert type -1 debug1: key_load_public: No such file or directory debug1: identity file /home/hogan/.ssh/id_dsa type -1 debug1: key_load_public: No such file or directory debug1: identity file /home/hogan/.ssh/id_dsa-cert type -1 debug1: key_load_public: No such file or directory debug1: identity file /home/hogan/.ssh/id_ecdsa type -1 debug1: key_load_public: No such file or directory debug1: identity file /home/hogan/.ssh/id_ecdsa-cert type -1 debug1: key_load_public: No such file or directory debug1: identity file /home/hogan/.ssh/id_ed25519 type -1 debug1: key_load_public: No such file or directory debug1: identity file /home/hogan/.ssh/id_ed25519-cert type -1 debug1: Local version string SSH-2.0-OpenSSH_7.6p1 Ubuntu-4ubuntu0.3 debug1: Remote protocol version 2.0, remote software version OpenSSH_8 +.2p1 Ubuntu-4ubuntu0.1 debug1: match: OpenSSH_8.2p1 Ubuntu-4ubuntu0.1 pat OpenSSH* compat 0x0 +4000000 debug1: Authenticating to 143.110.153.42:22 as 'wilma' debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug1: kex: algorithm: curve25519-sha256 debug1: kex: host key algorithm: ecdsa-sha2-nistp256 debug1: kex: server->client cipher: chacha20-poly1305@openssh.com MAC: + <implicit> compression: none debug1: kex: client->server cipher: chacha20-poly1305@openssh.com MAC: + <implicit> compression: none debug1: expecting SSH2_MSG_KEX_ECDH_REPLY debug1: Server host key: ecdsa-sha2-nistp256 SHA256:D6XoS17x+bi8QeACsX +mMrZeRDV9bOVcPIJ94zP9xZx4 debug1: Host '143.110.153.42' is known and matches the ECDSA host key. debug1: Found key in /home/hogan/.ssh/known_hosts:2 debug1: rekey after 134217728 blocks debug1: SSH2_MSG_NEWKEYS sent debug1: expecting SSH2_MSG_NEWKEYS debug1: SSH2_MSG_NEWKEYS received debug1: rekey after 134217728 blocks debug1: SSH2_MSG_EXT_INFO received debug1: kex_input_ext_info: server-sig-algs=<ssh-ed25519,sk-ssh-ed2551 +9@openssh.com,ssh-rsa,rsa-sha2-256,rsa-sha2-512,ssh-dss,ecdsa-sha2-ni +stp256,ecdsa-sha2-nistp384,ecdsa-sha2-nistp521,sk-ecdsa-sha2-nistp256 +@openssh.com> debug1: SSH2_MSG_SERVICE_ACCEPT received debug1: Authentications that can continue: publickey debug1: Next authentication method: publickey debug1: Offering public key: RSA SHA256:bBpP0w2TsMSLQyp0qTPPZ0pQFS5SZf +Rz4aS9S3xHjhA /home/hogan/.ssh/id_rsa debug1: Authentications that can continue: publickey debug1: Trying private key: /home/hogan/.ssh/id_dsa debug1: Trying private key: /home/hogan/.ssh/id_ecdsa debug1: Trying private key: /home/hogan/.ssh/id_ed25519 debug1: No more authentication methods to try. wilma@143.110.153.42: Permission denied (publickey).
