UNIX simulation software kea! X6.0 is very easy to use, just the registration code is extremely difficult to find. Today, I found that the system time can be modified to 2010, and then install, you can free of charge, haha!
When KEA! X is used, you can modify the Broadcast Address in Tools-> Configuration-> XDM Startup, for example, 192.168.109.255 to shield the machines of other subnets.
There is also a problem that the resolution is too high. Modify Tools-> Configuration-> Display- (WidTeh 1280, Hight 1024).
