Hi, I'm trying to modify the zope ftp-access to specify a port range within the server selects the ports for the passive ftp communication with the ftp-clients. This is in order to have the Zope server behind a firewall blocking more then the privileged ports only. I managed to modify the passive_acceptor within the medusa ftp server file. The problem I have is that certain FTP clients (e.g. gftp) close there connection because of messages coming from the server. The code I have modified is in /usr/lib/zope/ZServer/medusa/ftp_server.py class passive_acceptor (asyncore.dispatcher): ready = None def __init__ (self, control_channel): # connect_fun (conn, addr) asyncore.dispatcher.__init__ (self) self.control_channel = control_channel self.create_socket (socket.AF_INET, socket.SOCK_STREAM) to=open('/tmp/zope.log','a') for i in range(10000,11000): # bind to an address on the interface that the # control connection is coming from. to.write("ftp connection - port %d\n"%i) bres = self.bind (( self.control_channel.getsockname()[0], i )) to.write("ftp connection - bind:"+`bres`+"\n") if bres == None : break self.addr = self.getsockname() self.listen (1) to.close() Accessing the Zope-server through a firewall that has only the ports 10000 to 11000 open using gftp allows the firs connection but disconnects with an error message when I change the directory. The error message is: 451 Server Error: socket.error, (98,'Address already in use'): file: /usr/lib/zope/ZServer/medusa/asyncore.py line: 250 Do you have any hints on this?
