PowerShell - FTP Upload Script No Longer Working

@dafyre, I would have thought so because the @ is used for here-strings but powershell seems fine with them:
PS C:\Users\manxam> $test = "@"
PS C:\Users\manxam> echo $test
@
PS C:\Users\manxam> $test2 = '@'
PS C:\Users\manxam> echo $test2
@

But it is not powershell. it is System.Net.WebClient that is using it.

I am trying a winscp script. Haven't gotten in correct yet.

wrx7m

WinSCP doesn't like [email protected] syntax for the username either. WTF

What version of Windows does this run on?

When i try to run it (Windows 10), it crashes on the $uri line.

Server 2012 R2 (is where the FTP client/script is running)

because it is smarter and has credential variables to be supplied.

@JaredBusch So it looks like I will have to use url-encoding. However, I can't get this to work either.

@wrx7m Why don't you just use the (built-in) ftp client in windows?

ftp -s:filename_with_ftp_commands

Run whatever commands you need for instance:

open 10.43.0.0
[email protected]
user_password
put D:\Data\BAUPC.CSV /BAUPC.CSV
bye

Do it manually first so you know it works then just put the commands in the file.

PS. Here is a list of the command in the built-in windows ftp client. https://www.nsftools.com/tips/MSFTP.htm

@Pete-S I used to have that setup, but there was something that happened where it got deprecated or something like that. can't remember now. It was a couple of years ago. I will try it again.

wrx7m

@Pete-S it still gives login incorrect

Then you probably made a mistake somewhere.
Login works here with a username in the format [email protected]. Win7 client connecting to linux ftp server.
So it's not the windows ftp client that is the problem.

It could be that the server is requiring a SSL/TLS connection.

Then it would connect over normal FTP but switch to encryption before sending username/password. But then all firewall rules and whatnot have to be set right and the client also has to support TLS for it to work.

Is it a windows server you sending the file to? Then check what ftp server settings it has.

I tried using this on a local FTP server that I control using known usernames and passwords....

using user.name / MySecretPassword! works fine.

using [email protected] / MySecretPassword! does not work at all -- with the ftp command line, nor the .Net.Webclient for me.

The server is running ProFTPD. It is not running encryption, because I had to disable encryption in Filezilla in order to connect.

This server is managed by our web development consultants, so I told them what I had tried and that I was now out of ideas on how to connect. Suggested maybe they can revert to the old syntax, sans @domain.com for the user name.

It doesn't just affect ProFTPd... It also affects the FileZilla server as well.

Thanks for testing that out for me. I appreciate knowing that I am not crazy.

I assumed this was somehow related to how auth basic allows you to formulate your login as :
user:[email protected]
Therefore, the @ sign is being misinterpreted when it's being provided in a username.

With that in mind I went searching the interwebs and came across THIS confirming my suspicions.

Can you try replacing your @ sign with the + sign and let us know if it works? i.e.
wrx7m+gmail.com

Where I tried and it works fine was Win7pro built-in ftp client to Pure-FTPd server.

The [email protected] type names are VERY common on cpanel installations. I think it's referred to as long-form username.
So basically it's used by millions.

wrx7m

@Pete-S Yeah, I am not saying it isn't common. I find it very strange too.
