Oberon an attempt to put a file also gets "550 Permission denied".

I checked /etc/vsftpd.conf again and found this.
peter at joule:/home/peter$ grep write /etc/vsftpd.conf
# Uncomment this to enable any form of FTP write command.
#write_enable=YES

Ouch!  At the last system upgrade I allowed replacement of vsftpd.conf 
and forgot to restore adjustments.  Blunder.

Will work on that tomorrow or later.

Many thanks,                      ... P.
