.SH DESCRIPTION
|
||||
The
|
||||
.IR dnsquery
|
||||
program is a general interface to nameservers via
|
||||
BIND resolver library calls. The program supports
|
||||
queries to the nameserver with an opcode of QUERY.
|
||||
This program is intended to be a replacement or
|
||||
supplement to programs like nstest, nsquery and
|
||||
nslookup. All arguments except for
|
||||
.IR host
|
||||
and
|
||||
.IR ns
|
||||
are treated without case-sensitivity.
|
||||
.SH OPTIONS
|
||||
.TP 1i
|
||||
.B \-n
|
||||
The nameserver to be used in the query. Nameservers can appear as either
|
||||
Internet addresses of the form w.x.y.z or can appear as domain names.
|
||||
(default: as specified in /etc/resolv.conf)
|
||||
.TP 1i
|
||||
.B \-t
|
||||
The type of resource record of interest. Types include:
|
||||
.RS 1.5i
|
||||
.TP 1i
|
||||
A
|
||||

|

.PD 0

.B \-c
|

The class of resource records of interest.
|

Classes include:

||||
.RS 2i
|
||||
.TP 1i
|
||||
IN
|
||||
Internet
|

.PD 0

||||
.IP
|
||||
Note that any case may be used. (default: IN)
|
||||
.TP 1i
|
||||
.B \-r
|
||||
The number of times to retry if the nameserver is
|
||||
not responding. (default: 4)
|
||||
.TP 1i
|
||||
.B \-p
|
||||
Period to wait before timing out. (default: RES_TIMEOUT)
|
||||
.IR options
|
||||
field. (default: any answer)
|
||||
.TP 1i
|
||||
.B \-d
|
||||
Turn on debugging. This sets the RES_DEBUG bit of the resolver's
|
||||
.IR options
|
||||
field. (default: no debugging)
|
||||
.TP 1i
|
||||
.B \-s
|
||||
Use a
|
||||
.IR stream
|
||||
rather than a packet. This uses a TCP stream connection with
|
||||
the nameserver rather than a UDP datagram. This sets the
|
||||
RES_USEVC bit of the resolver's
|
||||
.IR options
|
||||
field. (default: UDP)
|
||||
.TP 1i
|
||||
.B \-v
|
||||
Synonym for the 's' flag.
|
||||
.TP 1i
|
||||
.B host
|
||||
The name of the host (or domain) of interest.
|
||||
.SH FILES
|
||||
/etc/resolv.conf to get the default ns and search lists
|
||||
.br
|
||||
<arpa/nameser.h> list of usable RR types and classes
|
||||
.br
|
||||
<resolv.h> list of resolver flags
|
||||
.SH "SEE ALSO"
|
||||
nslookup(8), nstest(1), nsquery(1),
|
||||
named(8), resolver(5)
|
||||
.SH DIAGNOSTICS
|
||||
If the resolver fails to answer the query and debugging has not been
|
||||
turned on,
|
||||
.IR dnsquery
|
||||
will simply print a message like:
|
||||
.TP 1i
|
||||
Query failed (rc = 1) : Unknown host
|
||||
.LP
|
||||
The value of the return code is supplied by h_errno.
|
||||
.SH BUGS
|
||||
Queries of a class other than IN can have interesting results
|
||||
since ordinarily a nameserver only has a list of root nameservers
|
||||
for class IN resource records.
|
||||
.PP
|
||||
Query uses a call to inet_addr() to determine if the argument
|
||||
for the '-n' option is a valid Internet address. Unfortunately,
|
||||
inet_addr() seems to cause a segmentation fault with some (bad)
|
||||
addresses (e.g. 1.2.3.4.5).
