RE: [squid-users] dns problem

Thanks.
This is the nscd.conf - doesn't look to have any nameservers?

# /etc/nscd.conf
#
# An example Name Service Cache config file. This file is needed by nscd.
#
# Legal entries are:
#
# logfile <file>
# debug-level <level>
# threads <initial #threads to use>
# max-threads <maximum #threads to use>
# server-user <user to run server as instead of root>
# server-user is ignored if nscd is started with -S parameters
# stat-user <user who is allowed to request statistics>
# reload-count unlimited|<number>
# paranoia <yes|no>
# restart-interval <time in seconds>
#
# enable-cache <service> <yes|no>
# positive-time-to-live <service> <time in seconds>
# negative-time-to-live <service> <time in seconds>
# suggested-size <service> <prime number>
# check-files <service> <yes|no>
# persistent <service> <yes|no>
# shared <service> <yes|no>
# max-db-size <service> <number bytes>
# auto-propagate <service> <yes|no>
#
# Currently supported cache names (services): passwd, group, hosts
#

# logfile /var/log/nscd.log
# threads 6
# max-threads 128
        server-user nscd
# stat-user nocpulse
        debug-level 0
# reload-count 5
        paranoia no
# restart-interval 3600

        enable-cache passwd yes
        positive-time-to-live passwd 600
        negative-time-to-live passwd 20
suggested-size passwd 211
        check-files passwd yes
        persistent passwd yes
        shared passwd yes
        max-db-size passwd 33554432
        auto-propagate passwd yes

        enable-cache group yes
        positive-time-to-live group 3600
        negative-time-to-live group 60
        suggested-size group 211
        check-files group yes
        persistent group yes
        shared group yes
        max-db-size group 33554432

        suggested-size hosts 211
        check-files hosts yes
