When a VM starts and configures it´s cvmfs the VM sends requests to a couple of cvmfs servers.
One of them is cvmfs02.grid.sinica.edu.tw.
The VM tries to connect to port 80 but will never get an answer as the server does not listen on that port.

nc -z -v -w 5 cvmfs02.grid.sinica.edu.tw 80
nc: connect to cvmfs02.grid.sinica.edu.tw port 80 (tcp) timed out: Operation now in progress



Instead the server responds on port 8000.

nc -z -v -w 5 cvmfs02.grid.sinica.edu.tw 8000
Connection to cvmfs02.grid.sinica.edu.tw 8000 port [tcp/irdmi] succeeded!



telnet cvmfs02.grid.sinica.edu.tw 8000
