ftp from Red Hat AS 4.4 to Open VMS System

[Troy Knabe]

Thanks to everyone who responded.  When you do an ls or dir on a remote 
host, it creates a "new" connection back to the server, so it is not 
persistent.  It appears to be grabbing a random port in the 53*** area.

Is there syntax in iptables to allow all ports from a host over port 1024?

I also had to issue the *passive* command once connected before I could 
run an ls or dir.

Thanks
