I was trying to ftp files to the zope web sever in my redhat linux sever.
zope ftp uses port 8021 so After open ws_ftp, I clicked connected, in the
session property/advaced i
set the remote port number to 8021.network timeout to 60. in
session property/General I set host name to my
linux sever name which the zope websever reside in, I put the root
manager name of zope website in the field of UserID and password and
cliked ok
it gives info as following:
connecting to 128.192.47.24:34864
200 port command successfully.
LIST
150 opening ascii node data connection for the list
!timer cancelled blocking call
!accept error: blocking call cancelled
!Retrieve of folder list failed (O)
I failed to do ftp with ws_ftp.
Any suggestions will be greatly appreciated!!
Thanks
we use iptables as firewall in the linux machine the iptables.rule is as
following
#==============================================================
# Iptables firewall script
#==============================================================
# Load modules
modprobe ip_tables
modprobe ip_conntrack
modprobe ip_conntrack_ftp
# Reset the rules
iptables -F
iptables -X
iptables -Z
# Setup default DROP policy
iptables -P INPUT DROP
iptables -P FORWARD DROP
iptables -P OUTPUT DROP

## LOOPBACK
# Allow unlimited traffic on the loopback interface.
iptables -A INPUT -i lo -j ACCEPT

#=======================================================================
## SYN-FLOODING PROTECTION
# This rule maximises the rate of incoming connections. In order to do
# this we divert tcp packets with the SYN bit set off to a user-defined
# chain. Up to limit-burst connections can arrive in 1/limit seconds
# ..... in this case 4 connections in one second. After this, one
# of the burst is regained every second and connections are allowed again.
# The default limit is 3/hour. The default limit burst is 5.

# iptables -N syn-flood
# iptables -A INPUT -i $IFACE -p tcp --syn -j syn-flood
# iptables -A syn-flood -m limit --limit 1/s --limit-burst 4 -j RETURN
# iptables -A syn-flood -j DROP
## Make sure NEW tcp connections are SYN packets
# iptables -A INPUT -i $IFACE -p tcp ! --syn -m state --state NEW -j LOG \
# --log-prefix "NonSYN New TCP: " --log-level warn
# iptables -A INPUT -i $IFACE -p tcp ! --syn -m state --state NEW -j DROP
#=====================================================================
## Fragments
# Deny and log all fragments except those from Fisher(nfs)(chg 11/9/01).
# iptables -A INPUT -i $IFACE -f -s $FISHER -j ACCEPT
