We've addressed this exact same question. This is the approach we've taken.
An IDL procedure writes out a temporary shell script containing the proper
commands, e.g.
#!/bin/csh
cd /mydir
ftp -n << done remote.computer.address
user username password
cd /mydir
ascii
put my.file "my.file"
quit
done
Then we spawn the commands
SPAWN, "source temporary.file", junk
SPAWN, "rm temporary.file", junk

I believe the problems you are having are due to insufficient
access rights for ftp on the server. I can do:
IDL> $ftp host
with no problems. If you put the file .netrc in your home
directory then you can connect without having to type username/pwds.
This file can include, among other things, lines like:
machine your-host login your-username password your-password
I recommend getting XFTP, a great gui ftp utility that is very
easy to use, and allows recursive transfers of directory structures.
You could SPAWN this program from within IDL:
spawn, 'xftp', /noshell, pid=pid
Note that IDL will be suspended until you quit the program. The
keyword PID returns the process ID of the program. The /NOSHELL
keyword is for UNIX only.
You can get XFTP from:

Hope this is useful.
