sftp – Use Network Drive in SFTP on Windows Server 2016

mappeddrivesftpsshwindows-server-2016

I'll start by specifying I'm not in the Sysadmin team at work, I work in another building with a small team and we are the "special cases". So they gave me full admin on our servers but I have no knowledge/power on the rest.

I have two servers, let's call them A and B.

A

Windows Server 2016

35 TB of hard drives

Local network

B

Windows Server 2016

200 GB

Behind firewalls, loadbalancers and such

OpenSSH (Only port 22 is open)

Mapped drive to server A on N:

I'm trying to let someone access the files on A by using sftp to server B. I tried symbolic links but it can't locate the folder when using WinSCP. I can't put the files on B since we have about 30 TB of data.

Any ideas? Thank you

Thanks to @eKKiM for the hint!

I couldn't run the service as the wanted SSH user, but by using the method used here : https://stackoverflow.com/a/7867064/3549186 I created a task to map the drive as the local System account and for the SSH user.

The symbolic link works perfectly now.

What port does SFTP use

While TCP port 22 is the general right answer, this is dependent on the fact that SSH is configured to use the standard port and not an alternative port.

As SFTP runs as a subsystem of SSH it runs on whatever port the SSH daemon is listening on and that is administrator configurable.

Ssh – Upload only SFTP with OpenSSH and Linux

ProFTPd definitely supports an ssh-emulation mode for sftp use, and I'm fairly sure it will have the usual array of ftpd-normal config options for forcing ownerships, controlling uploads, and the like. I think it would definitely be worth a look for your use. I can't help with the ftpd upload-only config, but here's my config code for getting the SFTP support:

LoadModule mod_sftp.c

<VirtualHost 12.34.56.78>
  SFTPEngine            on
  Port                  443
  SFTPLog               /var/tmp/proftpd-sftp.log
  SFTPHostKey           /etc/ssh/ssh_host_rsa_key
  SFTPHostKey           /etc/ssh/ssh_host_dsa_key
  DefaultRoot           /home/testuser
<Limit LOGIN>
  AllowGroup            sftponly
  DenyAll
</Limit>
</VirtualHost>

The Port 443 was because we already had sshd running on port 22, plus we had to support a bunch of clients behind a variety of deeply-stupid firewalls, and port 443 is about the only destination that almost all sites allow unencumbered. There's some other stuff there about limiting access to one group of users and chrooting them all into the same place, which you probably won't need, but I include it because I can affirm that that config works as-is.
