Thinking that the firewall might be an issue, I tried disabling it, but 
with no luck. 

The one peculiar behavior I see here is that this only seems to happen 
whenever the files reside in /usr/bin.  If I make a copy of them and put 
them into my home dir the problem goes away.
Additionally, if I make a copy of the files, and let them REMAIN in the 
/usr/bin dir, the problem still exists.

Some additional notes:
#1 - Copying the program to a different name under the SAME directory 
(/usr/bin)  does not cause the problem to go away, creating symlinks 
does not help either.  This means the problem is somehow related to 
something specific to the attributes of /usr/bin itself.
#2 - Considering the three programs found (ssh, ftp, telnet), there is a 
high probability that the root cause is related to how the "socket" or 
related api cmds are being invoked or differences in how it is being 
called when the application resides in the home directory versusus /usr/bin.
#3 - I have yet to find a complete list, but I am betting that this 
behavior will exist on all  applications trying to open a priviledged port.
