Directory Listing Fails on Windows 2008 IIS ftp server

[Chris Sutcliffe]

When I attempt to connect to Windows 2008 IIS ftp server I manage to connect, however when FileZilla attempts to list the directory contents it fails. Settings the debug level to 4 I see:

Command: LIST
Trace: CTransferSocket::OnConnect
Trace: CTransferSocket::OnConnect
Trace: CFtpControlSocket::OnReceive()
Response: 425 Can't open data connection.
Trace: CFtpControlSocket::TransferParseResponse()
Trace: code = 4
Trace: state = 4
Trace: CFtpControlSocket::ResetOperation(2)
Trace: CControlSocket::ResetOperation(2)
Trace: CFtpControlSocket::ParseSubcommandResult(2)
Trace: CFtpControlSocket::ListSubcommandResult()
Trace: state = 3
Trace: CFtpControlSocket::ResetOperation(2)
Trace: CControlSocket::ResetOperation(2)
Error: Failed to retrieve directory listing
Trace: CFileZillaEnginePrivate::ResetOperation(2)

Using the Windows FTP client, I am able to connect and list the directory contents without any error.

I'm not sure if it's relevant or not, but the user ID I have to use includes the domain (i.e. username = <domain>\<user ID>).

Please attach complete logs, snippets are of no use.

Attached is the full debug log, let me know if you need any additional information.

Status: Invalid character sequence received, disabling UTF-8. Select UTF-8 option in site manager to force UTF-8.

Your server is violating the FTP specifications, see ​http://wiki.filezilla-project.org/Character_Set
While this isn't directly related to the issue at hand, there's a very high probability that there's further brokenness with your server.

Regarding the original issue, the log is inconclusive. Most likely there's some broken router and/or firewall that is interrupting the connection. Please read ​http://wiki.filezilla-project.org/Network_Configuration for details.

The UTF-8 issue actually turned out to be the culprit. I forced it to UTF-8 for this server (which has a welcome message that contains both English and French) and I am able to connect and list the directory contents. Could this be a bug when FileZilla encounters mixed charsets?

Irregardless, I'm up and running now.

Thank you for your time!

No, cannot be a bug since not using UTF-8 violates the FTP standard. Whatever happens in that case is plain undefined. Everything is possible, pink bunnies and unicorns, you name it.

@HammerNL:

You do not have a similar issue, you have an entirely different issue. Please do not hijack tickets.

You didn't even notice that the ticket is for FileZilla Client while you are reporting a problem with the server.

Read before you post.
