What hex separates the password prompt from the status code? I guess
it's a different eol sequence that "^" doesn't catch for some reason.
It's \r\n. The code that matches it is
if string.match(result, "^230") then
I don't know if string.match is supposed to match embedded newlines?
It seems like the real problem is the line before:
status, result = socket:receive_lines(1);
Where receive_lines is returning more than one line. It's a wrapper for
nsock_readlines, which has this comment:
/* Read up to nlines lines (terminated with \n, which of course
inclues \r\n), or until EOF, or until the timeout, whichever comes
first. Note that NSE_STATUS_SUCCESS will be returned in the case
of EOF or tiemout if at least 1 char has been read. Also note that
you may get more than 'nlines' back -- we just stop once "at least"
'nlines' is read */
