FW: cant use "ls" from command line

["David Thomas" <biscut ntlworld com>]

At the risk of my looking incredibly stupid...please ignore the email
address that I used to send my question to the newsgroup...but the question
still stands though...

I have a windows machine able to browse the internet via my linux box and
can also browse FTP via HTTP but when it comes to using a DOS prompt on the
windows box then I can FTP to the site but cannot use "ls" as this causes
the FTP session to "hang", I have got the basic rc.firewall script running
and for all other purposes then that is running fine, is there any modules
etc that I need to include to get ls working via a DOS prompt?? I can use ls
fine to the site from the Linux machine...but it is just the windows machine
causing a problem, "dir" also has the same effect, if I connect to the
internet via dial up networking and then FTP to the site in a DOS prompt
then I dont have any problems, it is noly when going through IP MASQ/IP
Forwarding that I am having problems...

Thankyou for any help you can give
