Ftp put problem

Imran Hussain — Tue, 21 Dec 2004 00:09:24 GMT

Hello @ good day

I'm running a proxy server using RHEL Advance Server 3.0, squid 2.5 stable7 & masquerade with iptables. The clients complaining me that they are not able to put or get to any FTP server.

Conf r as follows

squid with standard settings

echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -t nat -A POSTROUTING -s 10.0.0.0/255.0.0.0 -o eth0 -j MASQUERADE
iptables -t nat -A PREROUTING -i eth1 -p tcp --dport 80 -j REDIRECT --to-port 8080

Thank u in advance

AFAIK, squid is HTTP/HTTPS proxy.

For ftp proxying you may use

http://www.linux.org/apps/AppId_6668.html

AFAIK & IMHO, ftp protocol doen't work well wit hproxy.
