FIXED THIS ISSUE --

Problem is a bug in the uClinux ftpd.c code.

I found a blog from 2003

Hello

I found a bug.

if "nm ftpd | sort -n" show:

1001cba8 b bufs.135

1001ce78 b ctrl_addr

1001ce88 b data_source

then ctrl_addr will be destroyed, and ftp client

will get message like this:

425 Can't create data socket (56.0.0.135,0): Cannot assign requested

address.

When I introduced this change in my ftpc.c the problem is resolved.

Anyone have any further comments on this and/or the above mentioned bug

report?

Thanks.

Basically, a fix for this problem was submitted way back then and is not in the current "ftpd.c" file (in uClinux-dist/user/ftpd directory). I made the fix, tested it and it works great. I can now mget with no problems.

Hope this helps someone else.
