Re: proftpd as a service under 2003

I'm having trouble getting proftpd to run as a service under 2003. I read /usr/share/doc/Cyginw/openssh.README. I used ssh-host-config to create an account named sshd_server. I have ssh running fine.

If I try to use the same account, I get the error

How did you setup proftpd as service?

cygrunsrv --install proftpd --path /usr/sbin/proftpd.exe --args "nodaemon" --type auto --disp "Cygwin proftpd" --desc "ProFTP FTP daemon" --user sshd_server -e CYGWIN="ntsec"

"cygrunsrv --start proftpd" after that fails.

  Error starting a service: QueryServiceStatus:  win32 error 1062:
  The service has not been started.

Looking in the logs, I have:

unable to set uid to 18, current uid: 1006

And 1006 is sshd_server? We know 18 is SYSTEM, whoever is 1006 has no privileges to change users... and it probably shouldn't (I have in my /etc/proftpd.conf User SYSTEM and Group None, it works fine in Win XP), if set as service the default is being run as SYSTEM, you must have changed that but not the proftpd configuration.

If I run without specifying --user, proftpd runs as SYSTEM. It does not change users at all. If I log in with other users and upload files, the files all end up owned by the SYSTEM user.

1006 is sshd_server, which does have permissions to change users, otherwise sshd wouldn't work under 2003. explains that the SYSTEM user does not have the "Create a token object" right under win2k3, which is required for set*id functions to work. ssh-host-config creates a user (sshd_server) which has those rights for running the ssh daemon. I am trying to re-use that user (which I have verified works with ssh) with proftpd

Running /usr/sbin/proftpd from the command line gives me the same error, except the current uid is 500.

The system is windows 2003 server. cygwin is 1.5.24.

Any ideas?

ProFtpd can be started from inetd... your choice; but there are advantages like using tcp_wrappers.

I don't have inetd installed. It's a stripped down installation. In any event, it's not clear to me that running from inetd would help. The problem seems to be related changing users, which proftpd would still have to do running under inetd.
