On the initial connection.

Here's the log from a Telnet session

jon-paris-computer:~ jonparis$ telnet frankieiii.frankenseries.com 21
Trying 65.183.178.117...
telnet: connect to address 65.183.178.117: Operation timed out
telnet: Unable to connect to remote host

jon-paris-computer:~ jonparis$ telnet partner400.com 21
Trying 63.167.147.110...
Connected to partner400.com.

So I can telnet to one system but not the other.  I also verified  
that the same scenario applies with FileZilla just in case it was  
misinterpreting a response.

So it would appear from this test that any firewall issue must be on  
the 400 side.  But if that is the case then why is it that I can  
connect via 5250 to another completely different 400 and then happily  
telnet to the problem system that failed above!  Doesn't that  
indicate that there is no firewall blocking port 21 on the box?

Since it is a straight timeout is there any point in doing a comms  
trace?
