AT&T Filtering FTP traffic?
- by xpda
Using an AT&T DSL, I cannot ftp upload or ftp download a few files of a large 1500 set.
The problem is the file name. I can change a few characters of the file name, and they upload fine. I can change the file names from upper to lower case and they upload fine. If I change back to the original file name, it will not upload again.
When it doesn't upload, it starts, transfers about 5% of a 5-10 meg file, and then times out.
I have uploaded one of the files under a different name, changed the name back to the original, and it will not download via ftp. It will download onto a browser, and it will ftp download just fine with a different name. It just will not download with ftp.
I have reproduced this uploading to three different servers on 1and1 and Amazon EC2. When I try it on a non-AT&T ISP client, it works OK.
Here is a file that did not upload until I had renamed it. (I have changed it back to the original name):

This problem is unrelated to connection, speed, and file content. Only things I can see that makes a difference are the file name and ATT DSL.
Does ATT have some kind of ftp file filtering? Is there anything else that could cause this behavior?
