Interactive +mode allows the user to query name servers for information about various +hosts and domains or to print a list of hosts in a domain. +Non\-interactive mode prints just the name and requested +information for a host or domain. +.SH ARGUMENTS +.sp +Interactive mode is entered in the following cases: +.INDENT 0.0 +.IP a. 3 +when no arguments are given (the default name server is used); +.IP b. 3 +when the first argument is a hyphen (\-) and the second argument is +the host name or Internet address of a name server. +.UNINDENT +.sp +Non\-interactive mode is used when the name or Internet address of the +host to be looked up is given as the first argument. The optional second +argument specifies the host name or address of a name server. +.sp +Options can also be specified on the command line if they precede the +arguments and are prefixed with a hyphen. For example, to change the +default query type to host information, with an initial timeout of 10 +seconds, type: +.INDENT 0.0 +.INDENT 3.5 +.sp +.nf +.ft C +nslookup \-query=hinfo \-timeout=10 +.ft P +.fi +.UNINDENT +.UNINDENT +.sp +The \fB\-version\fP option causes \fBnslookup\fP to print the version number +and immediately exit. +.SH INTERACTIVE COMMANDS +.INDENT 0.0 +.TP +.B \fBhost [server]\fP +This command looks up information for \fI\%host\fP using the current default server or +using \fBserver\fP, if specified. If \fI\%host\fP is an Internet address and the +query type is A or PTR, the name of the host is returned. If \fI\%host\fP is +a name and does not have a trailing period (\fB\&.\fP), the search list is used +to qualify the name. +.sp +To look up a host not in the current domain, append a period to the +name. +.TP +.B \fBserver domain\fP | \fBlserver domain\fP +These commands change the default server to \fBdomain\fP; \fBlserver\fP uses the initial +server to look up information about \fBdomain\fP, while \fBserver\fP uses the +current default server. If an authoritative answer cannot be found, +the names of servers that might have the answer are returned. +.TP +.B \fBroot\fP +This command is not implemented. +.TP +.B \fBfinger\fP +This command is not implemented. +.TP +.B \fBls\fP +This command is not implemented. +.TP +.B \fBview\fP +This command is not implemented. +.TP +.B \fBhelp\fP +This command is not implemented. +.TP +.B \fB?\fP +This command is not implemented. +.TP +.B \fBexit\fP +This command exits the program. +.TP +.B \fBset keyword[=value]\fP +This command is used to change state information that affects the +lookups. Valid keywords are: +.INDENT 7.0 +.TP +.B \fBall\fP +This keyword prints the current values of the frequently used options to +\fBset\fP\&. Information about the current default server and host is +also printed. +.TP +.B \fBclass=value\fP +This keyword changes the query class to one of: +.INDENT 7.0 +.TP +.B \fBIN\fP +the Internet class +.TP +.B \fBCH\fP +the Chaos class +.TP +.B \fBHS\fP +the Hesiod class +.TP +.B \fBANY\fP +wildcard +.UNINDENT +.sp +The class specifies the protocol group of the information. The default +is \fBIN\fP; the abbreviation for this keyword is \fBcl\fP\&. +.TP +.B \fBnodebug\fP +This keyword turns on or off the display of the full response packet, and any +intermediate response packets, when searching. The default for this keyword is +\fBnodebug\fP; the abbreviation for this keyword is \fB[no]deb\fP\&. +.TP +.B \fBnod2\fP +This keyword turns debugging mode on or off. This displays more about what +nslookup is doing. The default is \fBnod2\fP\&. +.TP +.B \fBdomain=name\fP +This keyword sets the search list to \fBname\fP\&. +.TP +.B \fBnosearch\fP +If the lookup request contains at least one period, but does not end +with a trailing period, this keyword appends the domain names in the domain +search list to the request until an answer is received. The default is \fBsearch\fP\&. +.TP +.B \fBport=value\fP +This keyword changes the default TCP/UDP name server port to \fBvalue\fP from +its default, port 53. The abbreviation for this keyword is \fBpo\fP\&. +.TP +.B \fBquerytype=value\fP | \fBtype=value\fP +This keyword changes the type of the information query to \fBvalue\fP\&. The +defaults are A and then AAAA; the abbreviations for these keywords are +\fBq\fP and \fBty\fP\&. +.sp +Please note that it is only possible to specify one query type. Only the default +behavior looks up both when an alternative is not specified. +.TP +.B \fBnorecurse\fP +This keyword tells the name server to query other servers if it does not have +the information. The default is \fBrecurse\fP; the abbreviation for this +keyword is \fB[no]rec\fP\&. +.TP +.B \fBndots=number\fP +This keyword sets the number of dots (label separators) in a domain that +disables searching. Absolute names always stop searching. +.TP +.B \fBretry=number\fP +This keyword sets the number of retries to \fBnumber\fP\&. +.TP +.B \fBtimeout=number\fP +This keyword changes the initial timeout interval to wait for a reply to +\fBnumber\fP, in seconds. +.TP +.B \fBnovc\fP +This keyword indicates that a virtual circuit should always be used when sending requests to the server. +\fBnovc\fP is the default. +.TP +.B \fBnofail\fP +This keyword tries the next nameserver if a nameserver responds with SERVFAIL or +a referral (nofail), or terminates the query (fail) on such a response. The +default is \fBnofail\fP\&. +.UNINDENT +.UNINDENT +.SH RETURN VALUES +.sp +\fBnslookup\fP returns with an exit status of 1 if any query failed, and 0 +otherwise. +.SH IDN SUPPORT +.sp +If \fBnslookup\fP has been built with IDN (internationalized domain name) +support, it can accept and display non\-ASCII domain names. \fBnslookup\fP +appropriately converts character encoding of a domain name before sending +a request to a DNS server or displaying a reply from the server. +To turn off IDN support, define the \fBIDN_DISABLE\fP +environment variable. IDN support is disabled if the variable is set +when \fBnslookup\fP runs, or when the standard output is not a tty. +.SH FILES +.sp +\fB/etc/resolv.conf\fP +.SH SEE ALSO +.sp +\fI\%dig(1)\fP, \fI\%host(1)\fP, \fI\%named(8)\fP\&. +.SH AUTHOR +Internet Systems Consortium +.SH COPYRIGHT +2023, Internet Systems Consortium +.\" Generated by docutils manpage writer. +. |
