仍然要求在ssh登录时输入密码
问题描述：
在一台运行在CentOS v6.2上的同一台目标机器上，我从我的Macbook和另一台Ubuntu机器上执行了相同的一套程序。 Macbook ssh无需登录即可正常工作，但Ubuntu服务器仍然无法连接到目标机器的无密码。以下是我所做的：仍然要求在ssh登录时输入密码
KEYNAME=~/.ssh/foo_key
# generate a new key
ssh-keygen -t rsa -f ${KEYNAME}
# fix permissions
chmod 600 ${KEYNAME}.pub ${KEYNAME}
# add key
eval `ssh-agent -s`
eval "$(ssh-agent)"
ssh-add ${KEYNAME}
# copy key to target machine foo
cat ${KEYNAME}.pub | ssh foo "cat - >> ~/.ssh/authorized_keys"
cat ${KEYNAME}.pub | ssh foo "cat - >> ~/.ssh/authorized_keys2"
2-然后我在Macbook和Ubuntu中的〜/ .ssh/config文件中添加了keyname。
3我确保将目标机器~/.ssh和~/.ssh/authorized*权限修复为700/750。

任何人都可以指导我为什么会发生这种情况？

我通常发现OpenSSH生成的日志在诊断这些问题时最有用。 – 2014-12-04 21:19:26
