Named provides DNS hostname resolution for the farm.physics.unh.edu backend network. DNS configuration files are located in the /var/named directory.
# Backups are 'pull' only. Too bad there isn't a better way to enforce this. read only = yes # Oh for the ability to retain CAP_DAC_READ_SEARCH, and no other. #uid = root # XXX There seems to be an obscure bug with pam_ldap and rsync whereby # getpwnam(3) segfaults when (and only when) archiving /etc. Using a numeric # uid avoids this bug. Only verified on Fedora Core 2. uid = 0 # There's not much point in putting the superuser in a chroot jail # use chroot = yes # This isn't really an effective "lock" per se, since the value is per-module, # but there really ought never be more than one, and it would at least # ensure serialized backups. max connections = 1 [usr_local] path = /usr/local comment = unpackaged software [opt] path = /opt comment = unpackaged software [etc] path = /etc comment = conf files [var] path = /var comment = user and system storage
