FTP

[Nobody's Hero]

Is there any way to force ftp to use port 80?

I believe with ipfilters you could forward all incoming port 21(ftp) connections to port 80. You'd also have to do something to the ftpd server, and that depends on which server you are using.

This might interfere with correct operation of your httpd server.

Port forwarding is easy with iptables for Linux. I WISH HP would port it.

Hi,

Yes. Change /etc/services file. Comment out http that is listed with 80 (only to avoid duplicate entries) and change ftp from 21 to 80. Restart inetd with inetd -c. You should see ftp (control) listening at port 80. Try

#ftp localhost

However, you will need to change the service lookup file on the client to point ftp to 80 there too. Otherwise the client will try to connect at port 21 and will get a connection refused message.
