Another couple of hours spent getting nowhere…
First, a reminder: you won’t be able to edit the fun_plug file on your windows computer with ‘normal’ editors. The file must be edited on unix format. I used http://www.vim.org editor for that.
Next: I believe I’ll have to enable telnet on the DSM. There’s a wiki howto on the same site as the previous post. That one worked perfectly, so now I can Telnet onto my dlink (whatever good that is for).
Any further help will be appreciated, or I’ll keep posting in about a week…
