我需要從使用ssh密鑰進行身份驗證的Linux服務器獲取配置文件。我被卡住了「Callback returned error」消息。RCurl SSH公鑰認證失敗:回調返回錯誤
conf = scp(host="10.10.10.10", path="/home/admin/codebase/config.txt",
user="admin", keypasswd = "", verbose=TRUE,
key=c("C:/echinn/.ssh/my_public_key", "C:/echinn/.ssh/my_private_key"))
我得到以下輸出
* Trying 10.10.10.10...
* Connected to 10.10.10.10 (10.10.10.10) port 22 (#0)
* SSH MD5 fingerprint: 8fa4562037d2f1e68c7ff419f9dc7656
* SSH authentication methods available: publickey,gssapi-keyex,gssapi-with-mic
* Using SSH public key file 'C:/echinn/.ssh/my_public_key'
* Using SSH private key file 'C:/echinn/.ssh/my_private_key'
* SSH public key authentication failed: Callback returned error
* Failure connecting to agent
* Authentication failure
* Closing connection 0
Error in function (type, msg, asError = TRUE) : Authentication failure
我也試圖與 「的getURL()」,但結束了同樣的錯誤。我能夠使用putty和WinSCP與(.ppk格式)相同的公鑰/私鑰成功連接。
在Linux服務器的/ var /日誌/安全我看到每個執行
sshd[xxxx]: Connection closed by x.x.x.x [preauth]
