NAME


drill - get (debug) information out of DNS(SEC)

SYNOPSIS


drill [ OPTIONS ] name [ @server ] [ type ] [ class ]

DESCRIPTION


drill is a tool to designed to get all sorts of information out of the DNS. It is
specificly designed to be used with DNSSEC.

The name drill is a pun on dig. With drill you should be able get even more information
than with dig.

If no arguments are given class defaults to 'IN' and type to 'A'. The server(s) specified
in /etc/resolv.conf are used to query against.

name Ask for this name.

@server Send to query to this server. If not specified use the nameservers from
/etc/resolv.conf.

type Ask for this RR type. If type is not given on the command line it defaults to 'A'.
Except when doing to reverse lookup when it defaults to 'PTR'.

class Use this class when querying.

SAMPLE USAGE


drill mx miek.nl Show the MX records of the domain miek.nl

drill -S jelte.nlnetlabs.nl
Chase any signatures in the jelte.nlnetlab.nl domain. This option is only available
when ldns has been compiled with openssl-support.

drill -TD www.example.com
Do a DNSSEC (-D) trace (-T) from the rootservers down to www.example.com. This
option only works when ldns has been compiled with openssl support.

drill -s dnskey jelte.nlnetlabs.nl
Show the DNSKEY record(s) for jelte.nlnetlabs.nl. For each found DNSKEY record also
print the DS record.

OPTIONS


-D Enable DNSSEC in the query. When querying for DNSSEC types (DNSKEY, RRSIG, DS and
NSEC) this is not automaticly enabled.

-T Trace name from the root down. When using this option the @server and the type
arguments are not used.

-S Chase the signature(s) of 'name' to a known key or as high up in the tree as
possible.

-I IPv4 or IPv6 address
Source address to query from. The source address has to be present on an interface
of the host running drill.

-V level
Be more verbose. Set level to 5 to see the actual query that is sent.

-Q Quiet mode, this overrules -V.

-f file
Read the query from a file. The query must be dumped with -w.

-i file
read the answer from the file instead from the network. This aids in debugging and
can be used to check if a query on disk is valid. If the file contains binary data
it is assumed to be a query in network order.

-w file
Write an answer packet to file.

-q file
Write the query packet to file.

-v Show drill's version.

-h Show a short help message.

QUERY OPTIONS
-4 Stay on ip4. Only send queries to ip4 enabled nameservers.

-6 Stay on ip6. Only send queries to ip6 enabled nameservers.

-a Use the resolver structure's fallback mechanism if the answer is truncated (TC=1).
If a truncated packet is received and this option is set, drill will first send a
new query with EDNS0 buffer size 4096.

If the EDNS0 buffer size was already set to 512+ bytes, or the above retry also
results in a truncated answer, the resolver structure will fall back to TCP.

-b size
Use size as the buffer size in the EDNS0 pseudo RR.

-c file
Use file instead of /etc/resolv.conf for nameserver configuration.

-d domain
When tracing (-T), start from this domain instead of the root.

-t Use TCP/IP when querying a server

-k keyfile
Use this file to read a (trusted) key from. When this options is given drill tries
to validate the current answer with this key. No chasing is done. When drill is
doing a secure trace, this key will be used as trust anchor. Can contain a DNSKEY
or a DS record.

Alternatively, when DNSSEC enabled tracing (-TD) or signature chasing (-S), if -k
is not specified, and a default trust anchor (/etc/unbound/root.key) exists and
contains a valid DNSKEY or DS record, it will be used as the trust anchor.

-o mnemonic
Use this option to set or unset specific header bits. A bit is set by using the bit
mnemonic in CAPITAL letters. A bit is unset when the mnemonic is given in
lowercase. The following mnemonics are understood by drill:

QR, qr: set, unset QueRy (default: on)
AA, aa: set, unset Authoritative Answer (default: off)
TC, tc: set, unset TrunCated (default: off)
RD, rd: set, unset Recursion Desired (default: on)
CD, cd: set, unset Checking Disabled (default: off)
RA, ra: set, unset Recursion Available (default: off)
AD, ad: set, unset Authenticated Data (default: off)

Thus: -o CD, will enable Checking Disabled, which instructs the cache to not
validate the answers it gives out.

-p port
Use this port instead of the default of 53.

-r file
When tracing (-T), use file as a root servers hint file.

-s When encountering a DNSKEY print the equivalent DS also.

-u Use UDP when querying a server. This is the default.

-w file
write the answer to a file. The file will contain a hexadecimal dump of the query.
This can be used in conjunction with -f.

-x Do a reverse loopup. The type argument is not used, it is preset to PTR.

-y <name:key[:algo]>
specify named base64 tsig key, and optional an algorithm (defaults to hmac-md5.sig-
alg.reg.int)

-z don't randomize the nameserver list before sending queries.

EXIT STATUS


The exit status is 0 if the looked up answer is secure and trusted, or insecure. The exit
status is not 0 if the looked up answer is untrusted or bogus, or an error occurred while
performing the lookup.
