I'm running Solaris 10 and I'm having issues with a particular network and need to replace host entries in my hosts file. I've updated the hosts file. Is there a refresh the hosts entries without a reboot?
No reboot required. But to be sure the changes take effect you can restart the nscd:
SMF should automatically restart the nscd.. or:
svcadm restart svc:/system/name-service-cache:default
Hope that helps.
