---- __NAME__ ndc - name daemon control program __SYNOPSIS__ ndc [[-c channel] [[-l localsock] [[-p pidfile] [[-d] [[-q] [[-s] [[-t] [[command] __DESCRIPTION__ This command allows the system administrator to control the operation of a name server. If no command is given, ndc will prompt for commands until it reads EOF. Options are: -c channel Specifies the rendezvous point for the controlchannel. The default is /var/run/ndc (a UNIX domain socket which is also the server's default control channel). If the desired control channel is a TCP/IP socket, then the format of the channel argument is __ipaddr/port__ (for example, __127.0.0.1/54__ would be TCP port 54 on the local host.) -l localsock This option will bind(2) the client side of the control channel to a specific address. Servers can be configured to reject connections which do not come from specific addresses. The format is the same as for channel (see above). -p pidfile For backward compatibility with older name servers, ndc is able to use UNIX signals for con- trol communications. This capability is optional in modern name servers and will disappear alto- gether at some future time. Note that the avail- able command set is narrower when the signal interface is used. A likely pidfile argument would be something like /var/run/named.pid. -d Turns on debugging output, which is of interest mainly to developers. -q Suppresses prompts and result text. -s Suppresses nonfatal error announcements. -t Turns on protocol and system tracing, useful in installation debugging. __COMMANDS__ Several commands are built into ndc, but the full set of commands supported by the name server is dynamic and should be discovered using the help command (see below). Builtin commands are: /help Provides help for builtin commands. /exitExit from ndc command interpreter./traceToggle tracing (see -t description above)./debugToggle debugging (see -d description above)./quietToggle quietude (see -q description above)./silentToggle silence (see -s description above).__NOTES__ If running in pidfile mode, any arguments to start and restart commands are passed to the new named on its command line. If running in channel mode, there is no start command and the restart command just tells the name server to execvp(3) itself. __AUTHOR__ Paul Vixie (Internet Software Consortium) __SEE ALSO__ named(8), 4th Berkeley !DistributionDecember 31, 1998 1 ----
