SSH 錯誤：ssh_dispatch_run_fatal：連接到 192.168.xx 埠 22：DH GEX 組超出範圍
我有 SSH 的問題。由於 DH GEX 組超出範圍，我無法 ssh 進入伺服器
我的 ssh 版本：
OpenSSH_7.2p2 Ubuntu-4ubuntu2.4，OpenSSL 1.0.2g 2016 年 3 月 1 日
我試圖通過 ssh 進入具有主機密鑰算法的伺服器：

謝謝閱讀！
該問題有三種可能的解決方案。
- 在客戶端，您應該升級新的 openssh7.2p
- 修改/etc/ssh/module（客戶端）
從起點到目標：
如果您想通過 ssh 從新的開放式 ssh 伺服器連接到已棄用的伺服器。只需嘗試以下命令
ssh -v -o KexAlgorithms=diffie-hellman-group14-sha1 -o HostKeyAlgorithms=+ssh-dss my.linux.com
