[Wylug-help] ftp setup

[Roger Beaumont]

My son (in China) wants to send me some files that are inconveniently large to
send as email attachments, so I set vsftpd running...

He can log in, 'ls' his home directory, and download, but cannot create a
directory or upload files to my machine.  When he tries he gets (for eg):
------------------------------------------------
Connected to 82.38.54.74:7062
STOR amber.jpg
550 Access is denied
------------------------------------------------
or

I've suggested that he tries 'ftp' from the (Doze) command line, but he says
that does the same as his gui s/w.

I've ssh'd into a friends machine (to get outside my firewall) and both sftp
and gftp (cli) let me log in (as my son), list directories, create
directories and upload files.

Any suggestions?
