could not load host key: /etc/ssh/ssh_host_rsa_key 无法启动ssh的一个解决办法
症状:
# /usr/sbin/sshd
系统提示“Could not load host key: /etc/ssh/ssh_host_key
Could not load host key: /etc/ssh/ssh_host_rsa_key
Could not load host key: /etc/ssh/ssh_host_dsa_key
Disabling protocol version 1. Could not load host key
Disabling protocol version 2. Could not load host key
sshd: no hostkeys available — exiting”
大致的意思就是需要某个key什么的。
解决办法如下:
#ssh-keygen -t dsa -f /etc/ssh/ssh_host_dsa_key
Generating public/private dsa key pair.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /etc/ssh/ssh_host_dsa_key.
Your public key has been saved in /etc/ssh/ssh_host_dsa_key.pub.
The key fingerprint is:
xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx root@localhost.localdomain
#ssh-keygen -t rsa -f /etc/ssh/ssh_host_rsa_key
Generating public/private rkey pair.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /etc/ssh/ssh_host_rsa_key.
Your public key has been saved in /etc/ssh/ssh_host_dsa_rey.pub.
root@localhost.localdomain
#/usr/sbin/sshd
这时候,就可以在windows底下使用putty连接这台linux主机了。
