/*
|
||||
* SYSEXITS.H -- Exit status codes for system programs.
|
||||
*
|
||||
* This include file attempts to categorize possible error
|
||||
* exit statuses for system programs, notably delivermail
|
||||
* and the Berkeley network.
|
||||
*
|
||||
* Error numbers begin at EX__BASE to reduce the possibility of
|
||||
* clashing with other exit statuses that random programs may
|
||||
* already return. The meaning of the codes is approximately
|
||||
* as follows:
|
||||
*
|
||||
* EX_USAGE -- The command was used incorrectly, e.g., with
|
||||
* the wrong number of arguments, a bad flag, a bad
|
||||
* syntax in a parameter, or whatever.
|
||||
* EX_DATAERR -- The input data was incorrect in some way.
|
||||
* This should only be used for user's data & not
|
||||
* system files.
|
||||
* EX_NOINPUT -- An input file (not a system file) did not
|
||||
* exist or was not readable. This could also include
|
||||
* errors like "No message" to a mailer (if it cared
|
||||
* to catch it).
|
||||
* EX_NOUSER -- The user specified did not exist. This might
|
||||
* be used for mail addresses or remote logins.
|
||||
* EX_NOHOST -- The host specified did not exist. This is used
|
||||
* in mail addresses or network requests.
|
||||
* EX_UNAVAILABLE -- A service is unavailable. This can occur
|
||||
* if a support program or file does not exist. This
|
||||
* can also be used as a catchall message when something
|
||||
* you wanted to do doesn't work, but you don't know
|
||||
* why.
|
||||
* EX_SOFTWARE -- An internal software error has been detected.
|
||||
* This should be limited to non-operating system related
|
||||
* errors as possible.
|
||||
* EX_OSERR -- An operating system error has been detected.
|
||||
* This is intended to be used for such things as "cannot
|
||||
* fork", "cannot create pipe", or the like. It includes
|
||||
* things like getuid returning a user that does not
|
||||
* exist in the passwd file.
|
||||
* EX_OSFILE -- Some system file (e.g., /etc/passwd, /etc/utmp,
|
||||
* etc.) does not exist, cannot be opened, or has some
|
||||
* sort of error (e.g., syntax error).
|
||||
* EX_CANTCREAT -- A (user specified) output file cannot be
|
||||
* created.
|
||||
* EX_IOERR -- An error occurred while doing I/O on some file.
|
||||
* EX_TEMPFAIL -- temporary failure, indicating something that
|
||||
* is not really an error. In sendmail, this means
|
||||
* that a mailer (e.g.) could not create a connection,
|
||||
* and the request should be reattempted later.
|
||||
* EX_PROTOCOL -- the remote system returned something that
|
||||
* was "not possible" during a protocol exchange.
|
||||
* EX_NOPERM -- You did not have sufficient permission to
|
||||
* perform the operation. This is not intended for
|
||||
* file system problems, which should use NOINPUT or
|
||||
* CANTCREAT, but rather for higher level permissions.

|
||||
.SH DESCRIPTION
|
||||
The
|
||||
.BR whois
|
||||
utility looks up records in the databases maintained by several
|
||||
Network Information Centers
|
||||
(NICs).
|
||||
.LP
|
||||
The options are as follows:
|
||||
.RS
|
||||
.B -6
|
||||
Use the IPv6 Resource Center (6bone) database.
|
||||
It contains network names and addresses for the IPv6 network.
|
||||
.B -A
|
||||
Use the Asia/Pacific Network Information Center (APNIC) database.
|
||||
It contains network numbers used in East Asia, Australia,
|
||||
New Zealand, and the Pacific islands.
|
||||
.B -a
|
||||
Use the American Registry for Internet Numbers (ARIN) database.
|
||||
It contains network numbers used in those parts of the world covered
|
||||
neither by APNIC nor by RIPE.
|
||||
.LP
|
||||
(Hint: All point of contact handles in the ARIN
|
||||
whois database end with "-ARIN".)
|
||||
.LP
|
||||
.B -b
|
||||
Use the Network Abuse Clearinghouse database.
|
||||
It contains addresses to which network abuse should be reported,
|
||||
indexed by domain name.
|
||||
.BI -c country-code
|
||||
This is the equivalent of using the
|
||||
.B -h
|
||||
option with an argument of
|
||||
"
|
||||
.IR country-code .whois-servers.net
|
||||
".
|
||||
.B -d
|
||||
Use the US Department of Defense
|
||||
database.
|
||||
It contains points of contact for subdomains of
|
||||
.IR MIL .
|
||||
.B -g
|
||||
Use the US non-military federal government database, which contains points of
|
||||
contact for subdomains of
|
||||
.IR .GOV .
|
||||
.BI -h host
|
||||
Use the specified host instead of the default variant.
|
||||
Either a host name or an IP address may be specified.
|
||||
.LP
|
||||
By default
|
||||
.BR whois
|
||||
constructs the name of a whois server to use from the top-level domain
|
||||
(TLD) of the supplied (single) argument, and appending
|
||||
".whois-servers.net".
|
||||
This effectively allows a suitable whois server to be selected
|
||||
automatically for a large number of TLDs.
|
||||
.LP
|
||||
In the event that an IP
|
||||
address is specified, the whois server will default to the American
|
||||
Registry for Internet Numbers (ARIN).
|
||||
If a query to ARIN
|
||||
references APNIC, LACNIC, or RIPE,
|
||||
that server will be queried also, provided that the
|
||||
.B -Q
|
||||
option is not specified.
|
||||
.LP
|
||||
If the query is not a domain name or IP address,
|
||||
.BR whois
|
||||
will fall back to
|
||||
.IR whois.crsnic.net .
|
||||
.B -I
|
||||
Use the Internet Assigned Numbers Authority (IANA) database.
|
||||
It contains network information for top-level domains.
|
||||
.B -i
|
||||
Use the Network Solutions Registry for Internet Numbers
|
||||
.RI ( whois.networksolutions.com )
|
||||
database.
|
||||
It contains network numbers and domain contact information for most of
|
||||
.IR .COM , .NET , .ORG and .EDU
|
||||
domains.
|
||||
.LP
|
||||
.BR NOTE !
|
||||
The registration of these domains is now done
|
||||
by a number of independent and competing registrars.
|
||||
This database holds no information on domains registered by organizations
|
||||
other than Network Solutions, Inc.
|
||||
Also, note that the
|
||||
InterNIC
|
||||
database
|
||||
.RI ( whois.internic.net )
|
||||
is no longer handled by Network Solutions, Inc.
|
||||
For details, see
|
||||
.IR http://www.internic.net/ .
|
||||
.LP
|
||||
(Hint: Contact information, identified by the term
|
||||
.IR handle ,
|
||||
can be looked up by prefixing "handle" to the NIC
|
||||
handle in the query.)
|
||||
.B -l
|
||||
Use the Latin American and Caribbean IP address Regional Registry
|
||||
(LACNIC) database.
|
||||
It contains network numbers used in much of Latin America and the
|
||||
Caribbean.
|
||||
.B -m
|
||||
Use the Route Arbiter Database (RADB) database.
|
||||
It contains route policy specifications for a large
|
||||
number of operators' networks.
|
||||
.BI -p port
|
||||
Connect to the whois server on
|
||||
.BR port .
|
||||
If this option is not specified,
|
||||
.BR whois
|
||||
defaults to port 43.
|
||||
.B -Q
|
||||
Do a quick lookup. This means that
|
||||
.BR whois
|
||||
will not attempt to lookup the name in the authoritative whois
|
||||
server (if one is listed).
|
||||
This option has no effect when combined with any other options.
|
||||
.B -R
|
||||
Use the Russia Network Information Center (RIPN) database.
|
||||
It contains network numbers and domain contact information
|
||||
for subdomains of
|
||||
.IR .RU .
|
||||
This option is deprecated; use the
|
||||
.BR -c
|
||||
option with an argument of "RU"
|
||||
instead.
|
||||
.B -r
|
||||
Use the R\(aaeseaux IP Europ\(aaeens
|
||||
(RIPE) database.
|
||||
It contains network numbers and domain contact information
|
||||
for Europe.
|
||||
.RE
|
||||
.LP
|
||||
The operands specified to
|
||||
.BR whois
|
||||
are treated independently and may be used
|
||||
as queries on different whois servers.
|
||||
.SH EXAMPLES
|
||||
Most types of data, such as domain names and IP
|
||||
addresses, can be used as arguments to
|
||||
.BR whois
|
||||
without any options, and
|
||||
.BR whois
|
||||
will choose the correct whois server to query.
|
||||
Some exceptions, where
|
||||
.BR whois
|
||||
will not be able to handle data correctly, are detailed below.
|
||||
.LP
|
||||
To obtain contact information about an
|
||||
administrator located in the Russian
|
||||
TLD domain
|
||||
"RU",
|
||||
use the
|
||||
.BR -c
|
||||
option as shown in the following example, where
|
||||
.I CONTACT-ID
|
||||
is substituted with the actual contact identifier.
|
||||
.LP
|
||||
.nf
|
||||
whois \-c RU CONTACT-ID
|
||||
\.fi
|
||||
.LP
|
||||
(Note: This example is specific to the TLD
|
||||
"RU", but other TLDs
|
||||
can be queried by using a similar syntax.)
|
||||
.LP
|
||||
The following example demonstrates how to obtain information about an
|
||||
IPv6
|
||||
address or hostname using the
|
||||
.BR -6
|
||||
option, which directs the query to 6bone.
|
||||
.LP
|
||||
.nf
|
||||
whois \-6 IPv6-IP-Address
|
||||
\.fi
|
||||
.LP
|
||||
The following example demonstrates how to query
|
||||
a whois server using a non-standard port, where
|
||||
``query-data'' is the query to be sent to
|
||||
``whois.example.com''
|
||||
on port ``rwhois''
|
||||
(written numerically as 4321).
|
||||
.LP
|
||||
.nf
|
||||
whois \-h whois.example.com \-p rwhois query-data
