I'm having a strange problem with the sshd configuration script on Windows 8.
I'm calling it as follows, where I expect both the fjsupport Windows user
account and /etc/passwd entry to be created by the script:
/bin/ssh-host-config -y -c ntsec -u fjsupport -w <the password>
If the user has no entry in /etc/passwd, it creates the Windows account, but
then complains when it comes to create the sshd service that the privileged
user does not exist (I think it means in /etc/passwd). If I add the user to
/etc/passwd (using mkpasswd after the first run) and just remove the Windows
account, then it sees that the user exists in /etc/passwd and does not attempt
to create a Windows account, then complaining that it cannot use the
(non-existent) Windows user when it tries to create the service. If I have both
the Windows account (with privileges) and the /etc/passwd entry beforehand,
everything is fine, but of course it doesn't have to make either.
By stepping through the script (incidentally, the -d flag doesn't work
properly?), I found that the csih_create_privileged_user function is using the
variable ${username} to write to /etc/passwd. But when called as above this
variable is not set. So that doesn't update /etc/passwd and it (later) thinks
the user is not known. This is at line 3069 in
cygwin-service-installation-helper.sh.
/usr/bin/mkpasswd -l -u "${username}" >> "${SYSCONFDIR}/passwd"
Changing ${username} to ${csih_PRIVILEGED_USERNAME} seems to fix the problem
and everything works as expected.
So I have the result I want, but I'm not sure that the fix above is correct.
Isn't it normal to use ssh-host-config to create the user in Windows and
/etc/passwd? In which case why isn't everyone getting this problem? Or am I
using the script the wrong way?
