Command-line didn't take the TunnelPasswordPlain="tunnel_pwd"

2022-11-11 05:39

Hi,
I use this command to connect to server by SCP through tunnel, but the command didn't take the TunnelPasswordPlain settting, it still ask me to put password manually, can you please tell me why? My command is like below:

C:\Program Files (x86)\WinSCP\WinSCP.exe scp://1.1.1.1/config/ssl/ /username=my_usn /password=my_pwd /rawsettings Shell="bash" Tunnel=1 TunnelHostName=8.8.8.8 TunnelPortNumber=22 TunnelUserName=my_tunnel_usn TunnelPasswordPlain=my_tunnel_pwd

Thank you very much,
James

Your command line looks god to me. Except that it misses double-quotes around the WinSCP.exe path. When I fix that, the tunnel password is propagated correctly to WinSCP.

Please attach a full session log file showing the problem (using the latest version of WinSCP).

To generate the session log file, use /log=C:\path\to\winscp.log command-line argument. Submit the log with your post as an attachment. Note that passwords and passphrases not stored in the log. You may want to remove other data you consider sensitive though, such as host names, IP addresses, account names or file names (unless they are relevant to the problem). If you do not want to post the log publicly, you can mark the attachment as private.

I still got Tunnel password prompt

2022-11-16 04:01

Thanks Martin, I can start the WinSCP without issue, so quote should not be an issue, it just didn't take the TunnelPasswordPlain="mytunnelpwd". I pasted the log and attached Tunnel Password Prompt screenshot above for your reference. What version did you test and tunnel password was taken?

Thanks,
James

If I put tunnel password manually the session will be connected

2022-11-16 04:33

More information, if I type tunnel password manually on the prompt then the session will be connected automatically.

If I run your command using the latest version of WinSCP form a batch file (with quotes added), it just works.

But I see in the log that you execute the command from Python.
I guess that's the missing piece, you didn't tell us about. Python probably passes something else to WinSCP than what you believe. Show us your Python code. You can also try enabling password logging (/loglevel=*) to see the real WinSCP command-line in the log. But ultimately, this is likely Python rather than WinSCP question.

Thanks Martin, it is not python issue, python the run WinSCP.exe within externally. I run the command from cmd and also popup tunnel password prompt, after I put tunnel password manually, the rest of connect can be completed automatically, please see the screenshot. It just didn't take the tunnel password as rawsetting.

Re: Command-line didn't take the TunnelPasswordPlain="tunnel_pwd"

If I run your exact command (just with enabled password logging):

WinSCP.exe /log=winscp.log /loglevel=* scp://example.com/config/ssl/ /username=username /password=password /rawsettings Shell="bash" Tunnel=1 TunnelHostName=tunnel.example.com TunnelPortNumber=22 TunnelUserName=tunnelusername TunnelPasswordPlain=tunnelpassword

I see in the log that the tunnel password is taken correctly:

. 2022-11-21 12:59:31.073 Tunnel: User name: tunnelusername (Password: tunnelpassword, Key file: No)

What do you get in the log if you do the same? Using the latest version of WinSCP (though I seem to be getting the same results even with 5.21.2).

Don't you have password storing disabled? (DisablePasswordStoring)

Thanks Martin, yes I have password disabled setting on registry, I have no permission to change it. Is this the reason? But why was session password taken? Only tunnel password was not taken.

Can you send me an email, so I can send you back a development version of WinSCP for testing? Please include a link back to this topic in your email. Also note in this topic that you have sent the email. Thanks.

You will find my address (if you log in) in my forum profile.

Thank you so much, it fixed the tunnel password cannot be taken issue with the 6.0dev version, the tunnel password was taken and I am able to start a session from cmd and login automatically.

Let me know when you release the official fixed version.

Thanks,
James
