Run nscd -g to see caching statistics and see if they tally with your usage. If all of them are misses then you need to run nscd in debug mode with 'nscd -d' to see why the caching is not working. Make sure you increase the value of debug-level to get verbose messages. An easy test is to use 'getent hosts <hostname>' and 'getent ahosts <hostname>' and study the nscd logs to see if you get a cache miss everytime. -- Siddhesh Poyarekar http://siddhesh.in -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
