Question FTP error


I am trying to ftp to an linux machine on my DMZ but cannot connect to it.

C:\>ftp "IP Address"
> ftp: connect :Unknown error number

Not sure what to look for in errors? I have another machine similar to this and that allows FTP connection. I have looked in /etc/hosts.allow file but neither of them have FTP in there. One is working and the other is not.

If I needed to add it in the /etc/hosts.allow file, how would I allow it to accept ftp from any of the internal networks? Thanks.

Maybe you can first try connecting to ports 20 and 21 on your FTP server.
To do this, execute:
Code:
telnet your_ftp_machine 20
telnet your_ftp_machine 21
where your_ftp_machine is the hostname of the computer in the DMZ to which you FTP.

I'm guessing the firewall is blocking FTP access. However, I can't really why this results in an unknown FTP error. It should tell you something like "access denied" or "connection closed".
