在一臺運行在CentOS v6.2上的同一臺目標機器上，我從我的Macbook和另一臺Ubuntu機器上執行了相同的一套程序。 Macbook ssh無需登錄即可正常工作，但Ubuntu服務器仍然無法連接到目標機器的無密碼。以下是我所做的：仍然要求在ssh登錄時輸入密碼
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-然後我在Macbook和Ubuntu中的〜/ .ssh/config文件中添加了keyname。
3我確保將目標機器~/.ssh和~/.ssh/authorized*權限修復爲700/750。
其他一些信息：
Ubuntu的協議版本號爲：
OpenSSH_5.9p1 Debian-5ubuntu1.1, OpenSSL 1.0.1 14 Mar 2012的Macbook協議版本號爲：
OpenSSH_6.2p2, OSSLShim 0.9.8r 8 Dec 2011目標的CentOS V6.2協議版本號爲：
OpenSSH_5.3p1, OpenSSL 1.0.1e-fips 11 Feb 2013
這是的結果：

任何人都可以指導我爲什麼會發生這種情況？
當ssh -vvv失敗時會說什麼？ – 2014-12-04 21:16:48
看到我更新的問題:) – Amir 2014-12-04 21:17:44
我通常發現OpenSSH生成的日誌在診斷這些問題時最有用。 – 2014-12-04 21:19:26
