ssh hostname -vvvTを実行すると以下のログが出る。
debug1: Trying private key: /c/Users/username/.ssh/mykey.pem debug3: sign_and_send_pubkey: RSA SHA256:nQr29X+3juJvSWOedeEVmgKCZgaO169LKCvAZCKkFKM debug3: sign_and_send_pubkey: signing using rsa-sha2-512 SHA256:nQr29X+3juJvSWOedeEVmgKCZgaO169LKCvAZCKkFKM debug3: send packet: type 50 debug2: we sent a publickey packet, wait for reply debug3: receive packet: type 51 debug1: Authentications that can continue: publickey,password debug2: we did not send a packet, disable method debug3: authmethod_lookup password debug3: remaining preferred: ,password debug3: authmethod_is_enabled password debug1: Next authentication method: password
「receive packet: type 51」はユーザの認証に失敗したという意味。 今回の原因は/home/username/.sshフォルダの権限が600になっていたため。正しくは700。 sshはほんとハマリやすい。。
