Fetch 3.0.3 Fails to PUT or GET Files Through SOCKS Proxy This article was written about products for which Microsoft no longer offers support. Therefore, this article is offered "as is" and will no longer be updated.
This article was previously published under Q190618 SYMPTOMS
Attempting to use the Fetch 3.0.3 FTP client to "PUT" or "GET" files
through SOCKS Proxy fails with the following error message if configured
to use Port-based connections:
"Error number -1"
CAUSE
This error occurs because of a malformed BIND request that the Fetch 3.0.3
client sends to the Proxy Server. When the BIND request is sent to the
SOCKS server, the request should also include a destination port. However,
with FETCH 3.0.3, a NULL value is sent to the SOCKS server, so the SOCKS
server rejects the request and closes the connection.
WORKAROUND
If Fetch 3.0.3 is configured to use a PASV mode connection to the ftp
server going through SOCKS Proxy, Fetch can successfully "GET" files
but still cannot "PUT" files successfully.
NOTE: The "PUT" command allows some data to pass through the Proxy Server but it aborts near completion of upload. Other Macintosh FTP clients are available that make successful BIND requests, allowing the client to use standard Port-based connections (that is, not PASV mode). MORE INFORMATION
