Hello,
This might be a problem with the related rules of a firewall between you and the server. What kind of firewall are you using on your Ubuntu server?
The problem is that, conntrack_ftp module, which on the fly allows ftp data connections to pass through firewall even if they were to be dropped because of rules, cannot analyze the encrypted stream for PASV/PORT commands. The same applies to not being able to use active mode from behind a firewall/nat with encrypted control connection.So you need to set static ports for passive mode (or if client is not behind firewall/nat use an active mode) and add a firewall rule to accept incoming connections on these ports. Ports for passive mode are set through PassivePorts directive.
Edit the ProFTPd config
edit line 47; uncomment the rule and change the ports to anything you like. Change
to
Now save the file and restart ProFTPd
Modify your firewall You need to allow the passive ports needed for FTP. How depends on the type of firewall you are running. For IPTables use the following command:
For UFW use the following:
Now try to connect once more! If you still got problems, please change your FileZilla language to english (so I can understand) and post the FULL log
AND WHEN THAT give command
iptables -NL | grep 587
Me Returns 2x This value :
ACCEPT tcp - tcp 0.0.0.0/0 0.0.0.0/0 DPT : 3510
For insert More Than Once with iptables. And now?
Hi friend, I could help with One more thing, quería exchange a 21 subparagraph standard port 3510. How do I like to proceed ?
I gave the command:
sudo iptables -A INPUT -p tcp --dport 1234 -j ACCEPT
AND
iptables -I INPUT -p tcp --dport 587 -j ACCEPT
But still closed. I’m using nmap to View the status of the door.
Thank you
