A lesson of GT

In order to meet the acceptance requirements, we have changed the IP address of the lab machine to an external IP address, and have done a lot of other things. Suddenly, the GT container cannot be started! Globus-start-container will die there, and nothing will be output! I mistakenly thought it was another problem or someone else changed some settings, so I wanted to reinstall gt4. The result is not installed yet!
Later, I thought that it was probably because I changed the IP address, but I didn't change the IP address in/etc/hosts. As a result, GT couldn't connect to the local machine.
In addition, the debug mode of JBuilder does not work either. A small window "activity monitor" appears, prompting that the virtual machine is being initialized, And the Hang is there.

Now/etc/hosts has been changed, and everything is normal. A lesson ......
