Done.  (Difficult with Mandrake SNF sans manual, but done.)
Now I can ftp to my ISP; connect; authenticate; do a pwd and get the
right response -- then ls/get/put etc. just hang the connection -- which
eventually times out at the client end, saying:

230 User <xxxxxxxx> logged in, access restrictions apply.
Remote system type is UNIX.
Using binary mode to transfer files.
ftp> pwd
257 "/u/x/x/x/xxxxxxxx" is current directory.
ftp> cd docs
250 CWD command successful.
ftp> ls
200 PORT command successful.
        . . . . .
425 Can't build data connection: Operation timed out.


Any clueful hints; comments?

[ Interestingly, sftp gives:

root@<lmachine> sftp <rmachine>.co.uk
Connecting to <rmachine>.co.uk...
Protocol major versions differ: 2 vs. 1
Connection closed

ISP (UK's biggest) now claims that Un*x is not supported by them; and on
being upbraided at supporting only Evil Empire boxen, responded : "At
the end of the day, all things said and done, it is _the_ standard,
isn't it?".
