Ftp failing to connect

I am using Linux, trying to connect to my ftp server using service-U in a remote data center.  I have an always on vpn connection to the data center. From a windows box, I can ftp just file to the server,  it from the Linux box, I keep on getting this error message.


First it says:
Connected to 10.2.x.x
421, service not available, remote server has closed connection

So I looked at the logs on my ftp connection and I didnt see any connection attempt.

Is this a Linux issue or my firewall, I'm thinking it's my firewall.

Which Linux dist are you running?
What does your firewall-log say?

I'm not sure what version of Linux I'm running because I did not install it.  How can I find out?  What command or give me the version?

I looked at the logs on the firewall but I didn't see much, The firewall log didn't show anything at all, but there's a few more logs I can look at, I'll do that this morning.
In terminal:
$ cat /etc/issue
And
$ uname -a
And post both answers.
test by chkconfig firewalld off -- then put back on if needed.

good deal.
Ahh, yeah that could be a problem ;)
But now you know how to disable firewalls in Ubuntu!
Good for you!

Thanks guys for providing that info.  I tried disabling, but that didn't do it.
It was my FTP server blocking the IP address, after I deleted it from being blocked, it works now.
