FTPWebRequest & AS/400 - Setting NAMEFMT to 1

Question

I'm trying to connect to a FTP AS/400 server using .NET, with a url like this:

ftp://server.com/folder/file.csv

I'm getting a 501 error in return, and according to this question it's due to the path separator or AS/400 not working with regular paths without setting NAMEFMT to 1.

Since I'm using the FTPWebRequest object, is there any way I can set NAMEFMT to 1 with a FTPWebRequest?

You need to send SITE NAMEFMT 1 as a QUOTE command.

See this related question: How to send arbitrary ftp commands in C#. It doesn't appear to be possible using FTPWebRequest.

Take a look at libcurl.NET.

Alternatively if you can force FTPWebRequest to make the 'first' file or pathname parameter received in a subcommand start with a slash (/) or a tilde (~) character the system will automatically enforce NAMEFMT 1. See File systems and naming conventions under the FTP reference information topic in the IBM i information center.

If you can make the connection refer to an IFS file (leading slash) it switches to namefmt 1. – Thorbjørn Ravn Andersen Jan 06 '12 at 12:02

Putting a slash ('/') in front of the file path did the trick. Thanks! – Code Slinger Jan 30 '12 at 22:56
