無法與gitlab建立ssh連接

Question

我在gitlab上有一個項目，我試圖推送一個提交。我首先用https url複製了項目，但之後將其改爲ssh，然後運行cat ~/.ssh/id_rsa.pub，它給了我ssh密鑰：我有拷貝將密鑰粘貼到我的gitlab配置文件中的ssh密鑰，但嘗試推送提交我收到一條消息：

主機'gitlab'的真實性無法建立。 RSA密鑰 指紋是SHA256：cZiqgz2tMzLXftNIIXmQ9v + 6M38xM1LzxROnDM1OJ0Q。 您確定要繼續連接（是/否）嗎？是 警告：將'07 .no，'myIpAddress'（RSA）永久添加到已知主機列表中。 權限被拒絕（公鑰）。

在運行ssh -Tv git@myEmail：

我該如何解決呢？

Answer 1

它告訴你，你從來沒有連接到這臺服務器。如果你期待這一點，這是非常正常的。如果您偏執，請使用備用渠道驗證密鑰的校驗和/指紋。 （但是請注意，有人可以重定向您的ssh連接，也可以重定向Web瀏覽器會話。）

如果您在從此安裝ssh之前已連接到此服務器，則服務器已用新密鑰重新配置或者某人在欺騙服務器的身份。由於中間人攻擊的嚴重性，它警告你可能性。

無論哪種方式，你都有一個安全的加密頻道給某人。沒有人沒有與指紋相對應的私鑰可以解碼您發送的內容。

您用來驗證自己身份的密鑰是無關的......您不希望將身份驗證信息發送給可能會竊取該密碼的欺詐服務器，因此您不應該期待任何更改，具體取決於您是否要使用密碼或私鑰進行登錄。你在這個過程中還沒有那麼遠。
