openssh如何配置启动sshd问题

Question

安装openssh是自动安装的。运行

sshd start

出现：
sshd re-exec requires execution with an absolute path

再运行

/usr/sbin/sshd

出现
Could not load host key: /etc/ssh/ssh_host_rsa_key
Could not load host key: /etc/ssh/ssh_host_dsa_key
Could not load host key: /etc/ssh/ssh_host_ecdsa_key
Disabling protocol version 2. Could not load host key
sshd: no hostkeys available -- exiting.
于是我就用

ssh-keygen -t dsa -f /etc/ssh/ssh_host_dsa_key

ssh-keygen -t rsa -f /etc/ssh/ssh_host_rsa_key

 ssh-keygen -t ecdsa -f /etc/ssh/ssh_host_ecdsa_key

在上面设置中，如果设置了密码，运行

/usr/sbin/sshd

还是出现

Could not load host key: /etc/ssh/ssh_host_rsa_key
Could not load host key: /etc/ssh/ssh_host_dsa_key
Could not load host key: /etc/ssh/ssh_host_ecdsa_key
Disabling protocol version 2. Could not load host key
sshd: no hostkeys available -- exiting.

如果不设置密码，就可以正常运行，这是什么原因呀。都研究了两三天了，还没有搞定。

Answer 1

Answer 3

根据你的提示执行：

    hb@hb-ubuntu:/usr/local/sbin$ ssh-keygen -t dsa -f
    usr/local/etc/ssh_host_dsa_keyGenerating public/private dsa key pair.
    Enter passphrase (empty for no passphrase): 
    Enter same passphrase again: 
    open usr/local/etc/ssh_host_dsa_key failed: No such file or directory.
    Saving the key failed: usr/local/etc/ssh_host_dsa_key.
这个错误又是咋回事？

Answer 4

我在ubuntu10.04中用的

    zlib-1.2.5.1.tar.gz

    openssl-1.0.0d.tar.gz

    openssh-5.6p1.tar.gz

使用非root用户，安装三个文件没啥问题，但执行sudo sshd时就出现和你一样的错误

这个问题半年没人回答，不知道楼主解决了没有？
