I have a Linux system (Red hat 5) and have configured Apache as a proxy server. The system works well if I use netscape on a Win 95 client. But WS_FTP95LE do not connect to other sites than my own Linux system. I have tried several configuration i the Advanced Box - Firewall but the aswer i that my server don't understand the command OPEN ftp.xxx.yyy. I can use ftp vithin Netscape.

I use port number 21 on both Netscape and my FTP-client

My question is: Can I use Apache proxy for ftp or is it neccesary to install something else? And what?
Or is my problem related to a configuration file?

How is the Netscape firewall configuration setup?

Is there an entry in the FTP proxy field?  Is it the same port number as the one that's used in the HTTP field?

I have set Netscape proxy to manual proxy configuration, and IP-adress to my servers adress and port number to 21

If you can actually FTP to the Linux box normally, then your Linux box is *not* running a proxy on port 21.  Check your inetd.conf file, this should confirm that inetd is actually launching ftpd.

I can now say with 90% certainty that you cannot use your regular FTP client with Netscape proxy.  Here's why...

I have not worked with Netscape proxy, so I couldn't say for sure.  But when using Microsoft Proxy Server, Netscape actually talks to the proxy using the HTTP protocol!  I have confirmed this using a network sniffer.

What you see as a directory listing on a FTP server is actually HTML that's been formatted by the proxy, who is the one generating the FTP requests.

So unless your FTP client can do HTTP, you cannot use that client with just this proxy server.

I suggest running another proxy in addition to Netscape proxy server, such as FWTK.  Or your can try using a SOCKS server, such as the free implementation of SOCKS5 from NEC.
