Some firewalls require that FTP data connections from the server originate from port 20, which is the standard port number for FTP data connections. User f has been backed up. For example, NcFTPd Server has an option to let you specify an IP address to use for PASV replies rather than the real IP address of the machine. As long as one side of the FTP session enables Keep Alive and has the heartbeat timer configured to a sensible value, this problem should be solved.
Anyhow, regardless of answer, I'll try it. –Alex R Nov 15 '09 at 23:02 I have done 2 tests and all have succeeded after applying this change. Solution 1: The network administrator of the server network can configure the firewall to allow in the entire ephemeral port range. Backup always worked fine untill the last update. https://ubuntuforums.org/archive/index.php/t-1944481.html ncftp / > dir > dir Cmd: PORT 192,168,1,36,221,20 200: PORT command successful.

- The most common problem is when the firewall the FTP server is behind is strict, i.e.
beas.tar or compania.tar for example... ncftpput /home/tmp/ramdileo/beas.tar.gz: could not send file to remote host. Can you ftp manually to the new remote backup server from your server. both files are transfer and have the correct size.

but i dont know how... If you cannot, look for error messsages and figure out why. You could use this option to have NcFTPd use the external IP address of the routing device and hope that packets sent to that address would be forwarded to the internal Check This Out From our PASV example above, we have: Server: 227 Entering Passive Mode (172,16,3,4,204,173) If left unaltered, the client would try to connect to port 52397 on the IP address 172.16.3.4.
you are not in a public network reachable by the FTP server, which is needed for active mode. Problem is that FTP is unreliable and sometimes just halts after a few downloads... Join the community of 500,000 technology professionals and ask your questions.
The ramifications for problem (1) are that routing devices must maintain state information for the control connection where the FTP conversation between client and server takes place, and subsequent data connections.
It's likely that it's the NAT state tables on the VM that are causing the timing out the control connection because of inactivity on that socket.
