WSL中启动sshd服务

在开启SSHD服务时报错.

sshd re-exec requires execution with an absolute path

用绝对路径启动,也报错如下:

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

解决方式:

# ssh-keygen -t dsa -f /etc/ssh/ssh_host_dsa_key
# ssh-keygen -t rsa -f /etc/ssh/ssh_host_rsa_key
# /usr/sbin/sshd

如果上述两个文件存在，仍然出现这个错误，那么试试 chmod 600 上述两个文件。

再次运行，报新的错误

Missing privilege separation directory: /run/sshd

需要创建/run/sshd目录

# mkdir /run/sshd
# /usr/sbin/sshd
