我正在設置Capistrano 3與一個新的服務器，所以我可以部署一個Rails應用程序，我目前卡住了。每當我運行任何cap production任務，出現這種情況：Capistrano：網絡不可達錯誤，但可以ssh到服務器
$ cap production deploy:setup
cap aborted!
Errno::ENETUNREACH: Network is unreachable - connect(2) for [IPv6addresshere]:22
我花了幾個小時試圖弄清楚了這一點，我不知道發生了什麼事情。因爲我擁有授權的密鑰設置，所以我可以像使用同一用戶的Capistrano無需密碼一樣使用ssh。另外，從遠程服務器，我可以ssh [email protected]罰款，因爲我配置了部署密鑰。
有什麼建議嗎？

你是否也在通過IPv6測試sshing？ – Doon
試試'ssh_options [：forward_agent] = true' –
@Doon好點。我剛剛嘗試通過IPv6 ssh'ing，它不會工作。我如何強制Capistrano使用IPv4？奇怪的是，如果我將'ssh_options [：user]'從'deploy'（一個新的ish部署用戶）更改爲另一個用戶名，我不會收到這個錯誤 - 但我確實需要使用deploy用戶。同樣，普通的'ssh deploy @ myserver'在我的機器上工作。 @SeanHuber謝謝，我已經這麼做了。 – Alex
