The ability to access EPICS channels appears to have disappeared at LHO when connected to h1hwinj:

[hinj@h1hwinj1 eric.thrane]$ ezcaread H1:CAL-INJ_TINJ_STATE
channel H1:CAL-INJ_TINJ_STATE not accessible

However, the same command works fine from cdsssh:

eric.thrane@cdsssh:~$ ezcaread H1:CAL-INJ_TINJ_STATE
H1:CAL-INJ_TINJ_STATE = 1

This problem appears to have occurred after ER7 since we would have seen errors during transient injections otherwise. Your assistance would be greatly appreciated.

The problem has been resolved.  An update turned on some rather restrictive network filtering.
