linux - TAILS 上的 OpenSSH 错误

Question

每个人都是我第一次发帖，想知道我做错了什么:) 请帮助我。所以，我使用 tails，决定使用 OpenSSH 连接到远程服务器(digitalocean)。生成的公钥和私钥，放置到/root/.ssh/。但是，当我尝试连接时，ssh -v root@11.11.11.11 这是调试后得到的结果。

root@amnesia:/home/amnesia# ssh root@11.11.11.11

也许我只是忘了添加一些简单的步骤，这已经让我困扰了 3 天..^^ :D

Answer 1

我认为问题出在这里；

FATAL: Failed to determine SOCKS server.
ssh_exchange_identification: Connection closed by remote host

似乎没有服务器监听 IP 地址 11.11.11.11。

这是您已知的有 ssh 服务器监听的域地址吗？如果答案是肯定的，我的建议是不要将 root 用户用作可以通过 ssh 登录的用户，因为这存在安全风险。我相信在 OpenSSH 中默认情况下不允许这样做。
