On the server/workstation and a portable ~/.ssh has 700 perms while the authorized_keys, known_hosts, and *.pub key files in that directory have 644 perms; the others are 600.
I copied (via USB flash drive) the id_ed25519.pub from each host to ~/.ssh/authorized_keys on the other host. Recognizing the target host's public key appears to be the problem (see the output from portable to desktop below) and I don't know how to fix this situation. Trying to connect to the portable (running Slackware-14.2) from the workstation (running Slackware-14.1) fails: $ ssh -vv typha OpenSSH_7.3p1, OpenSSL 1.0.1u 22 Sep 2016 debug1: Reading configuration data /home/rshepard/.ssh/config debug1: Reading configuration data /etc/ssh/ssh_config debug2: resolving "typha" port 21498 debug2: ssh_connect_direct: needpriv 0 debug1: Connecting to typha [192.168.55.6] port 21498. debug1: connect to address 192.168.55.6 port 21498: Connection refused ssh: connect to host typha port 21498: Connection refused Adding an additional 'v' to the command does not increase the output. From the portable to the workstation I get much more detailed verbosity but still no connection: $ ssh -vv salmo OpenSSH_7.2p2, OpenSSL 1.0.2h 3 May 2016 debug1: Reading configuration data /home/rshepard/.ssh/config debug1: Reading configuration data /etc/ssh/ssh_config debug2: resolving "salmo" port 21498 debug2: ssh_connect_direct: needpriv 0 debug1: Connecting to salmo [127.0.0.1] port 21498. debug1: connect to address 127.0.0.1 port 21498: Connection refused debug1: Connecting to salmo [192.168.55.1] port 21498. debug1: Connection established. debug1: key_load_public: No such file or directory debug1: identity file /home/rshepard/.ssh/id_dsa type -1 debug1: key_load_public: No such file or directory debug1: identity file /home/rshepard/.ssh/id_dsa-cert type -1 debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_7.2 debug1: Remote protocol version 2.0, remote software version OpenSSH_7.3 debug1: match: OpenSSH_7.3 pat OpenSSH* compat 0x04000000 debug2: fd 3 setting O_NONBLOCK debug1: Authenticating to salmo:21498 as 'rshepard' debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug2: local client KEXINIT proposal debug2: KEX algorithms: [email protected],ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,diffie-hellman-group-exchange-sha256,diffie-hellman-group-exchange-sha1,diffie-hellman-group14-sha1,ext-info-c debug2: host key algorithms: [email protected],ssh-ed25519,[email protected],[email protected],[email protected],[email protected],ecdsa-sha2-nistp256,ecdsa-sha2-nistp384,ecdsa-sha2-nistp521,rsa-sha2-512,rsa-sha2-256,ssh-rsa debug2: ciphers ctos: aes128-ctr,aes192-ctr,aes256-ctr,arcfour256,arcfour128,aes128-cbc,3des-cbc debug2: ciphers stoc: aes128-ctr,aes192-ctr,aes256-ctr,arcfour256,arcfour128,aes128-cbc,3des-cbc debug2: MACs ctos: [email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],hmac-sha2-256,hmac-sha2-512,hmac-sha1 debug2: MACs stoc: [email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],hmac-sha2-256,hmac-sha2-512,hmac-sha1 debug2: compression ctos: none,[email protected],zlib debug2: compression stoc: none,[email protected],zlib debug2: languages ctos: debug2: languages stoc: debug2: first_kex_follows 0 debug2: reserved 0 debug2: peer server KEXINIT proposal debug2: KEX algorithms: [email protected],ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,diffie-hellman-group-exchange-sha256,diffie-hellman-group16-sha512,diffie-hellman-group18-sha512,diffie-hellman-group14-sha256,diffie-hellman-group14-sha1 debug2: host key algorithms: ssh-ed25519 debug2: ciphers ctos: [email protected],aes128-ctr,aes192-ctr,aes256-ctr,[email protected],[email protected] debug2: ciphers stoc: [email protected],aes128-ctr,aes192-ctr,aes256-ctr,[email protected],[email protected] debug2: MACs ctos: [email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],hmac-sha2-256,hmac-sha2-512,hmac-sha1 debug2: MACs stoc: [email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],hmac-sha2-256,hmac-sha2-512,hmac-sha1 debug2: compression ctos: none,[email protected] debug2: compression stoc: none,[email protected] debug2: languages ctos: debug2: languages stoc: debug2: first_kex_follows 0 debug2: reserved 0 debug1: kex: algorithm: [email protected] debug1: kex: host key algorithm: ssh-ed25519 debug1: kex: server->client cipher: aes128-ctr MAC: [email protected] compression: none debug1: kex: client->server cipher: aes128-ctr MAC: [email protected] compression: none debug1: expecting SSH2_MSG_KEX_ECDH_REPLY debug1: Server host key: ssh-ed25519 SHA256:9T1sRfIPmzJvODsTIOexYiBawQAJp6fN9GS1S9zGewg debug1: Host '[salmo]:21498' is known and matches the ED25519 host key. debug1: Found key in /home/rshepard/.ssh/known_hosts:1 debug2: set_newkeys: mode 1 debug1: rekey after 4294967296 blocks debug1: SSH2_MSG_NEWKEYS sent debug1: expecting SSH2_MSG_NEWKEYS debug2: set_newkeys: mode 0 debug1: rekey after 4294967296 blocks debug1: SSH2_MSG_NEWKEYS received debug2: key: /home/rshepard/.ssh/id_dsa ((nil)) debug1: SSH2_MSG_EXT_INFO received debug1: kex_input_ext_info: server-sig-algs=<rsa-sha2-256,rsa-sha2-512> debug2: service_accept: ssh-userauth debug1: SSH2_MSG_SERVICE_ACCEPT received debug1: Authentications that can continue: publickey debug1: Next authentication method: publickey debug1: Trying private key: /home/rshepard/.ssh/id_dsa debug2: we did not send a packet, disable method debug1: No more authentication methods to try. Permission denied (publickey). The only key type I specified with ssh-keygen (on both hosts is ed25519; no dsa present. I'm looking forward to learning what I did incorrectly and correcting it so I don't make the same error with other hosts.
