我試圖登錄/部署到Ubuntu服務器是我的Rails應用程序，但突然今天上午我無法登錄那裏。無法SSH /部署任何東西到Ubuntu服務器
當我運行SSH ssh [email protected] -p 420並輸入密碼，我得到一個消息，密碼不正確，消息Permission denied, please try again.
當我嘗試部署一些代碼Capistrano的，我得到：
connection failed for: IP (Net::SSH::AuthenticationFailed: deployer)
密碼也是正確的。
今天發生了這個問題，昨天是一切正常工作。 我仔細檢查了Capistrano的設置，但一切正確設置在那裏。
如何檢查該問題？從哪兒開始？它看起來像今天它停止工作。

當我運行ssh -v [email protected] -p 420
謝謝。
您可以嘗試在詳細模式下運行手動SSH命令以檢查嘗試的身份驗證模式 –
@ yohann.martineau感謝您的評論。剛剛添加了'ssh -v'的輸出。 – user984621
防火牆問題？你可以在這臺主機上運行nmap嗎？ –
