Strange xhost behavior- Please help!!

[Harold L Hunt II]

Jozsef,

You example makes no sense at all.  The problem is that 127.0.0.1 is a 
fake address that is only used for connections that loop back to the 
local machine that you are on.  You cannot connect across the network to 
the machine with address 127.0.0.1 because *every* machine on the 
network has the idea that it is machine 127.0.0.1.  You need to use the 
real IP address of that machine that you want to connect to, and make 
sure that you can actually ping it before trying this again.
