Hi All...
 

On a recent Cygwin install on a new win7-64 machine, I ran into a problem. The ssh service would not start because the protection on the /etc/ssh_host_rsa_key was too weak. (I use only the rsa host key.)

If I chmod the file to 600, all is well. But...if I do it within a shell script, the chmod has no effect. Below is a short test case and a bash -x run of the script?
 

$ cat test-config
chown administrators /etc/ssh*
ls -al /etc/ssh_host_rsa_key
chmod -v 600 /etc/ssh_host_rsa_key
ls -al /etc/ssh_host_rsa_key
$ cat test-config
chown administrators /etc/ssh*
ls -al /etc/ssh_host_rsa_key
chmod -v 600 /etc/ssh_host_rsa_key
ls -al /etc/ssh_host_rsa_key
 

$ bash -x test-config
+ chown administrators /etc/ssh_host_rsa_key /etc/ssh_host_rsa_key.pub /etc/sshd_config
+ ls -al /etc/ssh_host_rsa_key
-rw-rw---- 1 Administrators root 1675 Apr 4 11:30 /etc/ssh_host_rsa_key
+ chmod -v 600 /etc/ssh_host_rsa_key
mode of `/etc/ssh_host_rsa_key' changed from 0660 (rw-rw----) to 0600 (rw-------)
+ ls -al /etc/ssh_host_rsa_key
-rw-rw---- 1 Administrators root 1675 Apr 4 11:30 /etc/ssh_host_rsa_key

This test was on a fresh (1.7.12) from this morning.
 

Long term, this may be a csih issue, but I was just making a workaround for now...but my workaroung failed to workaround.

Thanks,
