Cannot connect to any FTP server no matter what FTP program I use.

Expand Post »
Hi guys/gals

I'm having the most frustrating time trying to connect to FTP servers in order to upload files. I try to connect to a number of different FTP servers and cannot connect to any of them.

I've tried connecting to the same servers using the same FTP programs on a second machine and it has no issues at all.

I've done ping and tracert tests on the machine with the issues and the internet connection is definitely NOT the problem. I've looked at network settings but with my little knowledge about networks I've not been able to see if there are any issues. Both PCs have the same network setup so I doubt it's a network issue.

I'm at a loss, anyone come across a similar issue?

Re: Cannot connect to any FTP server no matter what FTP program I use.
You may have outbound FTP filtered. type iptables-save as root on the command prompt and paste the data back here.

Also are the two machines you tested on the same LAN? IE
10.1.1.1 = router
10.1.1.2 = broken machine
10.1.1.3 = working machine

And you have confirmed they are using the same default gateway? Paste the output of route -n in linux to get the gateway. In windows type route print .

Also on the nonworking linux machine paste the output of:
telnet ftp.kernel.org 21
It should look like this:
text Syntax (Toggle Plain Text)
  1. root@svn:~/devex# telnet ftp.kernel.org 21
  2. Trying 149.20.20.133...
  3. Connected to pub.us.kernel.org.
  4. Escape character is '^]'.
  5. 220 Welcome to ftp.kernel.org.

But yours doesn't work so it will probably look like:
text Syntax (Toggle Plain Text)
  1. root@svn:~/devex# telnet ftp.kernel.org 21
  2. Trying 149.20.20.133...
  3. telnet: Unable to connect to remote host: Connection refused

Or after 30 seconds it may never finishing and just sit at the "Connecting...."

The type of error you see will help determine what the problem may be

Thanks for your reply sknake. I found what my issue was. My firewall went haywire and wasn't letting any connections on port 21 through.

drwxr-xr-x 2 root root 4096 2009-11-27 15:29 ./
drwxr-xr-x 146 root root 12288 2010-01-10 11:29 ../
