I just installed CentOS 5.4 on a rackspace cloud server and installed virtualmin which all seemed to go fine. The only problem I have is that I can not access the virtual servers directories via FTP.

I get the following from filezilla:

Status: Connecting to 1.1.1.1:21...
Status: Connection established, waiting for welcome message...
Response: 220 FTP Server ready.
Command: USER username
Response: 331 Password required for username.
Command: PASS ***************
Response: 230 User username logged in.
Status: Connected
Status: Retrieving directory listing...
Command: PWD
Response: 257 "/" is current directory.
Command: TYPE I
Response: 200 Type set to I
Command: PASV
Response: 227 Entering Passive Mode (1,1,1,1,216,214)
Command: LIST
Error: Connection timed out
Error: Failed to retrieve directory listing

and I get this from my /var/secure/log file

Any help would be greatly appreciated, I'm not totally new to Linux but it's not my strongest subject. I do like to know exactly why problems occur though and how exactly to fix them so the more detail the better!

cheers
