    升级前好好的,升级后,ssh 密钥就无法连接之前的服务器了,搜索了一下发现升级后会改变密钥

    我重新生成密钥,公钥丢服务器上了,但是还是无法连接,windows 客户端正常,唯独 mac 不行,-v 的提示好像没有什么有意义的内容,最后一句是 client_loop: send disconnect: Broken pip

    命令:ssh [email protected] 地址 -p 6800 -v -i .ssh/id_rsa

    明明是都已经 Authentication succeeded (publickey) 了。后面被踢掉估计是别的原因了。
    我 big sur 登 ssh 好好的啊。

    有人说 /etc/ssh/ssh_config 里加这一句可以搞定。估计是新版和你的服务器有啥不兼容的情况
