Fedora 23无密码ssh密钥在自动添加主机中不起作用 [英] Fedora 23 passwordless ssh key not working in automated host addition

问题描述

我已经安装了Fedora 23，并尝试使用以下方式进行无密码登录:

I have installed Fedora 23 and have tried to do a passwordless login with:

# ssh-copy-id ~/.ssh/id_dsa.pub user@host

已成功将密钥复制到主机，并且我已经在以下位置签入了主机:

which successfully copies the key to the host machine and I have checked in the host machine in:

# tail -n10 ~/.ssh/authorized_keys

我的PC名称存在于最后一行，但是在尝试登录时:

and my PC name exists as the last line but when trying to login:

# ssh user@host

我被要求输入密码！我试图登录到Ubuntu和CentOS并获得相同的结果.之前，我已经在多个Linux发行版(包括Fedora 21，CentOS和Ubuntu)上做到了这一点，而且效果很好.

I am asked for a password! I have tried to login to Ubuntu and CentOS and get the same result. I have done this previously with multiple linux distros including Fedora 21, CentOS and Ubuntu and it works just fine.

我需要这样做来完成自动添加主机的脚本，该脚本添加了一个主机，然后自动登录(add_user_host):

I need this to do finish the automated host addition script which adds a host and then logs in automatically (add_user_host):

#!/bin/bash
ssh-copy-id ~/.ssh/id_dsa.pub $1@$2;
ssh $1@$2;

您所要做的就是运行:

# add_user_host user host

推荐答案

Openssh-7.0已过时的DSA密钥.要使用它们，您需要在ssh_config中指定PubkeyAcceptedKeyTypes +ssh-dss(如

Openssh-7.0 obsoleted DSA keys. To use them you need to specify PubkeyAcceptedKeyTypes +ssh-dss in your ssh_config (as mentioned in your linked thread) to make them working, or rather use other keys (RSA, ed25519).
