我在使用 ssh 進行遠端伺服器連線時遇到問題。我在 xxx.xxx.xxx.xx1 上有一個伺服器 A，預設連接埠為 22。現在我想使用 ssh 從 serverA 連接 serverB。我使用了以下命令
[userA@localhost~] # ssh userB@serverB
當我運行此命令時，出現以下錯誤
ssh: connect to host xxx.xxx.xxx.xx1 port 22: No route to host
當我登入 serverA 時，又會看到這樣的提示 [用戶A@本地主機~]#
我不明白為什麼它顯示為上面的粗體文本，而它應該顯示為
[userA@serverA ~] #
任何人都有解決此問題的想法。
