Great, Thanks! That did the trick.
But how do I find out this stuff???
I did a LOT of googling to find instructions for installing yafc, uftp, cmdftp etc but ALL of them seem to have disappeared!!!
(@lleachii : yes, of course. But I guess the number of newbies makes it necessary to say)
Yes, I did that and it spewed errors of the form "/usr/bin/ssh: Ignoring unknown configuration XXX".
I went on to read many pages detailing options and came to the conclusion that sftp does not do FTP!
Thanks for the suggestion anyway.
I've now learnt how to use Luci to search packages and found 'lftp' which works as is without yet another learning curve!
Thanks, I already found 'lftp' using Luci/packages/filter, but I didn't know I could do 'opkg list -A' | grep xxx' which I find preferable to using a gui and will do so in future.
