sudo ssh：加载 pubkey 权限被拒绝

用户1需要能够su用户2在主机1，然后 ssh 到主机2使用公钥认证。密钥位于/home/user2/.ssh/id_rsahost1 上。它适用于sudo -s...

[user1@host1] $ sudo -u user2 -s
[user2@host1] $ ssh host2
Welcome to Ubuntu 20.04.2 LTS (GNU/Linux 5.4.0-70-generic x86_64)
...
Last login: ...
[user2@host2] $

但这不起作用...

[user1@host1] $ sudo -u user2 ssh host2

问题是，为什么？

答案1

当我将 ssh 密钥从外部驱动器复制到新机器时，我遇到了同样的问题。

chmod 600 ~/.ssh/*
chmod u=rw,go= ~/.ssh/*
chmod 644 ~/.ssh/id_rsa.pub
chmod 700 ~/.ssh
