vsftp error

Hi all,


I have just set up vsFTP on fedora 6. Everything works fine on my company?s LAN.


However, I found I can not connect FTP server from outside world (e.g. from my home machine),


I got error message like ?ftp: connect :Unknown error number?. I can ping the server machine, just cannot ftp to it.


What could cause this problem? DNS ?Thanks for any tips.

Re: vsftp error

What's your firewall look like? In particular, are you using a stateful firewall (-m state)?

Are you doing any NAT in order to get the server to work from external?

Shalom,

I think this is a firewall problem.

use the nmap command to check what ports are open.

nmap firewall

Re: vsftp error

I receive "ftp: connect :Unknown error number" if the vsftpd daemon cannot be contacted.

This most likely will be because of a firewall configuration problem, but also could be the listen_address configuration parameter in vsftpd.conf.

Check your firewall with system-config-securitylevel
