[Discuss] puzzle

i have three laptops running on my local t-mobile network,
all running fc37.

/etc/hosts is identical for all three, except for 127.0.0.1
which is host specific:

  127.0.0.1        localhost localhost.localdomain
  127.0.0.1        aldeberan aldeberan.localdomain
  192.168.12.148   alphacent alphacent.localdomain
  192.168.12.171   aldeberan aldeberan.localdomain
  192.168.12.221   rigel     rigel.localdomain
  192.168.12.117   HP_DeskJet_2700_series_0A85DE HP_DeskJet_2700_series_0A85DE.localdomain
  50.87.218.82     bluedan

the t-mobile app sees all three (and the printer).
aldeberan and rigel can ping everything, except alphacent.
alphacent can ping 192.168.12.148, bluedan, mit.edu, but nothing
else on the net (destination host unreachable).

i seem adept at ridiculous problems.  any thoughts?

tia,
ole dan
