Hi, I'm trying to get the FtpProxyAnonRO class to also allow the LIST command so an 'ls' can be issued by the client. I added the following line to Ftp.py in the FtpProxyAnonRO class: self.request["LIST"] = (FTP_REQ_ACCEPT) I also applied iptables rules to allow ports 40000:41000 between the hosts. Ethereal shows that the LIST command never arrives from a client going through the firewall. A "Connection refused" error is returned to the client. Clients not going through the firewall work. What am I missing?
