.sh 1 "Domain Management" .pp This section contains information for starting, controlling and debugging named. .sh 2 /etc/rc.local .pp The hostname should be set to the full domain style name in /etc/rc.local using hostname\|(1). The following entry should be added to /etc/rc.local to start up named at system boot time: .(b l if [ -f /etc/named ]; then /etc/named [options] & echo -n ' named' >/dev/console fi .)b This usually directly follows the lines that start syslogd. Do Not attempt to run named from inetd. This will continuously restart the name server and defeat the purpose of having a cache. .sh 2 /etc/named.pid .pp When named is successfully started up it writes its process id into the file /etc/named.pid. This is useful to programs that want to send signals to named. The name of this file may be changed by defining PIDFILE to the new name when compiling named. .sh 2 /etc/hosts .pp The gethostbyname\|() library call can detect if named is running. If it is determined that named is not running it will look in /etc/hosts to resolve an address. This option was added to allow ifconfig\|(8C) to configure the machines local interfaces and to enable a system manager to access the network while the system is in single user mode. It is advisable to put the local machines interface addresses and a couple of machine names and address in /etc/hosts so the system manager can rcp files from another machine when the system is in single user mode. The format of /etc/host has not changed. See hosts\|(5) for more information. Since the process of reading /etc/hosts is slow, it is not advised to use this option when the system is in multi user mode. .sh 2 Signals .pp There are several signals that can be sent to the named process to have it do tasks without restarting the process. .sh 3 Reload .pp SIGHUP - Causes named to read named.boot and reload the database. All previously cached data is lost. This is useful when you have made a change to a data file and you want named\|'s internal database to reflect the change. .sh 3 Debugging .pp When named is running incorrectly, look first in /usr/adm/messages and check for any messages logged by syslog. Next send it a signal to see what is happening. .pp SIGINT - Dumps the current data base and cache to /usr/\|tmp/\|named_dump\|.\|db This should give you an indication to whether the data base was loaded correctly. The name of the dump file may be changed by defining DUMPFILE to the new name when compiling named. Note: the following two signals only work when named is built with DEBUG defined. .pp SIGUSR1 - Turns on debugging. Each following USR1 increments the debug level. The output goes to /usr/tmp/named.run The name of this debug file may be changed by defining DEBUGFILE to the new name before compiling named. .pp SIGUSR2 - Turns off debugging completely. For more detailed debugging, define DEBUG when compiling the resolver routines into /lib/libc.a. .sx 0
.b ACKNOWLEDGEMENTS .pp Many thanks to the users at U.C. Berkeley for falling into many of the holes involved with integrating BIND into the system so that others would be spared the trauma. I would also like to extend gratitude to Jim McGinness and Digital Equipment Corporation for permitting me to spend most of my time on this project. .pp Ralph Campbell, Doug Kingston, Craig Partridge, Smoot Carl-Mitchell, Mike Muuss and everyone else on the DARPA Internet who has contributed to the development of BIND. To the members of the original BIND project, Douglas Terry, Mark Painter, David Riggle and Songnian Zhou. .pp Anne Hughes, Jim Bloom and Kirk McKusick and the many others who have reviewed this paper giving considerable advice. .pp This work was sponsored by the Defense Advanced Research Projects Agency (DoD), Arpa Order No. 4871 monitored by the Naval Electronics Systems Command under contract No. N00039-84-C-0089.
