Install sshd with cygwin

Question

I want to use cygwin to install sshd in windows. But when I start the sshd service, it says:

The CYGWIN sshd service is starting. The CYGWIN sshd service could not be started. The service did not report an error. More help is available by typing NET HELPMSG 3534. 

And sshd.log says:

 Permissions 0660 for '/etc/ssh_host_dsa_key' are too open. It is required that your private key files are NOT accessible by others. This private key will be ignored. bad permissions: ignore key: /etc/ssh_host_dsa_key Could not load host key: /etc/ssh_host_dsa_key 

So how to deal with it?

Answer 1

You need to make sure that only cyg_server user can access these keys.

 chown cyg_server /etc/ssh* chmod 600 /etc/ssh* 

These commands do just that and allow your sshd to work correctly.

Answer 2

My /var/log/sshd.log had this at the end:

 Disabling protocol version 2. Could not load host key sshd: no hostkeys available -- exiting. /var/empty must be owned by root and not group or world-writable. /var/empty must be owned by root and not group or world-writable. /var/empty must be owned by root and not group or world-writable. /var/empty must be owned by root and not group or world-writable. 

Looking at / var, I saw this:

 $ ls /var -All total 0 drwxrwxr-x+ 1 xxxx None 0 Dec 8 15:59 cache drwxrwxr-x+ 1 cyg_server root 0 Dec 8 16:21 empty drwxrwxr-x+ 1 xxxx None 0 Dec 8 15:58 lib drwxrwxrwx+ 1 xxxx None 0 Dec 8 16:27 log drwxrwxrwx+ 1 xxxx None 0 Dec 8 15:48 run drwxrwxrwt+ 1 xxxx None 0 Dec 8 15:48 tmp 

So I just made chmod 600 /var/empty and fixed it!
