Did you open the correct passive FTP ports in the firewall?

open the correct passive FTP ports in the firewall

Yes I think so

Hey, @pml_orion, could you please double-check the rule and confirm if the passive port range is 49152-65535? You might also want to double-check the instructions in this article. I hope that helps.

What is the output of the following command? (it shows the current rules loaded into the INPUT firewall table )

iptables -S INPUT

 

[AYamshanov]

Just another idea that makes sense to check: if the VM is deployed somewhere in a cloud, does the cloud have a cloud firewall with its own rules? If yes, maybe it blocks ftp traffic.

Hay algo más que pueda revisar?? Anything else to check?

 

[Raul A.]

Interesting. All the required ports are open. It should work.

Can you try with an additional ftp user? Can you try from a different computer?

 

[pml_orion]

I tried in two diferents computers...

 

[Raul A.]

Check if there are any other PassivePorts directives

grep -ir PassivePorts /etc/proftp*

 

[pml_orion]

That's what I get

What do you see in /var/log/auth.log when you conect via ftp?

tail -f /var/log/auth.log

As AYamshanov said, is the public IP set on the server?

hostname -I

A lot of "noise" in the log.

tail -f /var/log/auth.log | grep proftpd

 

[pml_orion]

 

[Raul A.]

Interesting. It should work. Can you try with a newer Filezilla version or with a different FTP client?

FTP modules are loaded?

lsmod | grep ftp

I have

nf_nat_ftp 20480 0
nf_nat 57344 4 nf_nat_ftp,nft_chain_nat,iptable_nat,xt_REDIRECT
nf_conntrack_ftp 24576 1 nf_nat_ftp
