[SOLVED] Linux to Windows sharing WITHOUT manual password entry

trickydba · 11-16-2016, 10:29 AM

I really don't know what version of Windows is running on the Windows Share but I just found out some info about the Win Share:

File Transfer Protocol = SFTP-3
Cryptographic protocol = SSH-2

Would this cause issues with connecting via Linux?

Where did you find that information?

smbclient which uses CIFS is not the same as ssh. WinSCP is a sftp client which connects to the linux ssh server.

For windows 7 Click the Start button The Start button, enter Computer in the search box, right-click Computer, and then click Properties

For Windows 8.x click Settings, and then click Change PC settings. Look under Windows for the version and edition of Windows that your PC is running

For Windows 10, goto start, enter "about your PC" and then select "about your PC"

I don't have access to the Windows Share server

So maybe I should be using sftp. That is what is being used in the Powershell script that is taking care of this file transfer from linux to windows. I think I tried every combination of sftp and still no success. I have the host key that is being used in the Powershell script but I do not know how to use it in sftp in Linux. I tried everything!!

You need to install a sftp server on your windows box.

Try this
smbclient -L windows_IP_address

Just press the enter key when prompted for a password

Look for something like:
Domain=[WORKGROUP] OS=[Windows 10 Home 14393] Server=[Windows 10 Home 6.3]

It will also display your default windows shares if there are any

Ok ok, good news!!! I used sftp username@hostname and got a prompt asking for the password. Inputted the password and sftp> showed up, which means Im in!!!! Only problem is I need this non-interactive, all automated. Also, after getting to the "sftp>" prompt, how do I copy to the Win Share?

michaelk · 11-16-2016, 10:58 AM

What username and hostname did you use? Did you use the same username and password that you enter in WinSCP?

trickydba · 11-16-2016, 11:58 AM

Yes i did. Is this format wrong:

SFTP WinUserName%WinUserPwd@hostname

trickydba · 11-16-2016, 12:22 PM

Is there any way I can put the password in a sftp command? I tried sftp username@hostname, entered password at the prompt and was happily shown "sftp>". Only problem is I need the password to be included so I don't have to input it.

Your connecting to the linux box not windows. You need to install a sftp server on windows. Dont have time at the moment to explain the client server model.

trickydba · 11-16-2016, 01:23 PM

It is installed on the Windows side. That's how I am able to use WinSCP and the Powershell script

Ok...so type in "sudo" before the command. Or become the root user and run the command. Not difficult.

It's only this hard because you're dealing with a Windows machine.

Is there a way I can actually put the host key in a bash script? This is very frustrating. Everything I need to be done can be done but I have to MANUALLY input a password. Once I get past having to input the password manually, everything else will be easy to put in my bash script

You did not fully explain your configuration and I made some wrong assumptions ie. did not pay enough attention to the details. The private key is typically located in your users home/.ssh directory. The default key name is id_rsa. To specify a key on the command line use the -i option. If you created your keys with puttygen then it has to be converted to the ssh format via putty.

I have actually installed the package expect and my issue has been resolved. Not the best because it it unsecure, but it's a short term solution. Here is the code:

expect -c "
spawn sftp username@hostname
expect "assword"
send "password is here\r"
expect "sftp>"
send "cd /folder to place file\r"
expect "sftp>"
send "put *.DAT\r"
expect "sftp>"
send "exit\r"
interact "

You might not need all of the lines but I needed to do certain things. Hope this helps!
