Hello Mat,
first of all thank you a lot for all the nice and brilliant software you
gave us for free ! Yesterday I sucessfully installed NSQUERY on my
DECmcc-station (on UCX020D). Our domain-admins (used to use unix/nslookup)
do like it a lot !!!
For HELP on all the PD tools on our hosts, I created a
SYS$TOOLS:TOOLS.HLB. I made a .HLP out of your NSQUERY_DOC.TXT
(shortened and slightly modified) and included it in our TOOLS.HLB.
Here it is, if you'd like to include it in your next distribution.
Regards
Christian

1 NSQUERY
NSQUERY is designed to be invoked as a DCL "foreign command":
$ NSQ*UERY :== $disk:[dir]NSQUERY
This command issues a query to an Internet domain server and displays
the resultant reply.
FORMAT
NSQUERY query-name [server]
_______________________________________________________
Command Qualifiers Defaults
/PORT=number /PORT=53
/PROTOCOL=proto /PROTOCOL=UDP
/[NO]RECURSIVE /NORECURSIVE
/TYPE=qtype /TYPE=ALL
/CLASS=qclass /CLASS=INTERNET
_______________________________________________________
2 Parameters
query-name
Name about which information should be obtained. This should be an
internet dotted domain-style name. If query-name is a numeric IP
address in dotted decimal form (e.g., 128.113.1.5), NSQUERY will
automatically make an inverse query by reversing the address segments
and adding ".IN-ADDR.ARPA".
All resource records defined in RFC 1035 are interpreted by NSQUERY.
Refer to that RFC for information about the abbreviations used in the
resource record display. All "time-to-live" values are displayed as
VMS delta-time strings. Authoritative responses and truncated
messages are noted before the resource records are displayed.
server
Server to be queried. If omitted, NSQUERY translates the logical name
NSQ_SERVER to obtain the server name. If there is no such logical
name or it cannot be translated, NSQUERY prompts for the name of the
server. If the server's name has multiple addresses, all addresses
are obtained and each is tried until a query is successfully sent and
reply received.
2 Qualifiers
/PORT
/PORT=port
Directs the query to the specified TCP or UDP port. If omitted, port
53 (the port used by most, if not all, domain servers) is used.
/PROTOCOL
/PROTOCOL=proto
Selects either TCP or UDP protocol. The default is UDP. UDP is
generally used for simple domain queries; TCP is generally only used
for major domain system events, such as zone transfers.
/RECURSIVE
/[NO]RECURSIVE
Sets the recursion desired bit in the query. If the server being
queried supports recursion and does not have the requested
information cached, it will make queries of other servers on your
behalf until the query is answered. NSQUERY will notify you if the
server does not support recursive queries.
/TYPE
/TYPE=qtype
Selects the type of resource record to be returned about the name.
The default is ALL, which selects all available resource record
types. Available types are as follows:
Type/QType_______Description___________________________
A host address
NS authoritative name server
MD mail destination (obsolete)
MF mail forwarder (obsolete)
CNAME canonical name for an alias
SOA start of zone authority
MB mailbox domain name (experimental)
MG mail group member (experimental)
MR mail rename domain name
(experimental)
NULL null resource record
WKS well-known service description
PTR domain name pointer
HINFO host information
MINFO mailbox or mail list information
MX mail exchange
TXT text strings
AXFR complete zone transfer
MAILB all mailbox-related records (MB, MG,
MR)
MAILA all_mail_agent_records_(obsolete)
Refer to RFC 1035 for a complete description of resource record types
and their uses. Note that not all servers support all record types.
You should probably never attempt to use the AXFR query type.
/CLASS
/CLASS=qclass
Selects the class of resource records to be returned. The default is
INTERNET. Available qclass values are:
Class/QClass_____Description___________________________
INTERNET the Internet
CSNET the CSNET class (obsolete)
CHAOSNET the CHAOS class
HESIOD the Hesiod class
ALL all_classes
