I have a rehat 7.1 linux sever with zope running on it. I use iptables as firewall. The firewall for zope webserver is all following: ----------------------------------------------------------------------- ## Zope iptables -A INPUT -i $IFACE -p tcp --dport 8080 -j ACCEPT # Allow inbound ftp iptables -A INPUT -i $IFACE -p tcp --dport 8021 -m state --state \ NEW,ESTABLISHED -j ACCEPT iptables -A OUTPUT -o $IFACE -p tcp --sport 8021 -m state --state \ ESTABLISHED -j ACCEPT ----------------------------------------------------------------------- I am trying to use ws_ftp to send files to zope. The problem is that if I stop the iptables firewall, it can connect to zope by the port8021. and i can see all directories in Romote Site (here is zope sever), and everything works fine. but when i start the iptables firewall, it still can connect to zope but i can not see the directories in the remote site. therfore i can not sent file to zope. what wrong with this firewall rules and how to fix it? Thanks. -------------------------------- Jianping Zhu Department of Computer Science Univerity of Georgia Athens, GA 30602 Tel 706 5423900 --------------------------------
