DESCRIPTION

13       drill  is a tool to designed to get all sorts of information out of the
14       DNS. It is specificly designed to be used with DNSSEC.
15
16       The name drill is a pun on dig. With drill you should be able get  even
17       more information than with dig.
18
19       The  arguments to drill may be placed in any order. If no arguments are
20       given class defaults to 'IN' and type to 'A'. The  server(s)  specified
21       in /etc/resolv.conf are used to query against.
22
23
24       @server  Send  to  query to this server. If not specified use the name‐
25       servers from /etc/resolv.conf.
26
27
28       type Ask for this RR type. If type is not given on the command line  it
29       defaults  to 'A'. Except when doing to reverse lookup there is defaults
30       to 'PTR'.
31
32
33       name Ask for this name.
34
35
36       class Use this class when querying.

SAMPLE USAGE

40       drill mx miek.nl Show the MX records of the domain miek.nl
41
42
43       drill -S jelte.nlnetlabs.nl
44              Chase any signatures a the jelte.nlnetlab.nl domain.
45
46
47       drill -TD www.example.com
48              Do a DNSSEC  (-D)  trace  (-T)  from  the  rootservers  down  to
49              www.example.com.
50
51
52       drill -s dnskey jelte.nlnetlabs.nl
53              Show the DNSKEY record(s) for jelte.nlnetlabs.nl. For each found
54              DNSKEY record also print the DS record.
55
56

OPTIONS

58       -D     Enable DNSSEC in the  query.  When  querying  for  DNSSEC  types
59              (DNSKEY, RRSIG, DS and NSEC) this is automaticly enabled.
60
61
62       -S     Chase the signature(s) of 'name' to a known key or as high up in
63              the tree as possible.
64
65
66       -T     Trace name from the  root  down.  When  using  this  option  the
67              @server and the type arguments are not used.
68
69
70       -V     Be  more  verbose.  Enable once for more messages on the screen.
71              Enable twice for a hexdump of the packets sent.
72
73
74       -4     Stay on ip4. Only send queries to ip4 enabled nameservers.
75
76
77       -6     Stay on ip6. Only send queries to ip6 enabled nameservers.
78
79
80       -a     Don't try the next nameserver on SERVFAIL. The default is to  do
81              this.
82
83
84       -b size
85
86
87
88       -c     Use TCP/IP when querying a server.
89
90
91
92       -f file
93              Read the query from a file. The query must be dumped with -w.
94
95
96       -i file
97              read  the  answer  from  the file instead from the network. This
98              aids in debugging and can be used to check if a query on disk is
99              valid.   If  the file contains binary data it is assumed to be a
100              query in network order.
101
102
103       -k keyfile
104              Use this file to read a (trusted) key from. When this options is
105              given  drill tries to validate the current answer with this key.
106              No chasing is done.
107
108
109       -p port
110              Use this port instead of the DNS default of 53.
111
112
113       -r     Don't set the RD bit in the query - the default is yes.
114
115
116       -s     When encountering a DNSKEY print the DS also.
117
118
119       -u     Use UDP when querying a server. This is the default.
120
121
122       -v
123
124
125       -w file
126              write the answer to a file. The file will contain a  hexadecimal
127              dump of the query. This can be used in conjunction with -f.
128
129
130       -x     Do a reverse loopup. The type argument is not used, it is preset
131              to PTR.
132
133

DNSSEC

135       When calling drill with -S it chases down signatures (RRSIG) to a known
136       key.  This uses a bottom-up approach.  [Jelte please fill in the blanks
137       here]
138
139       With -TD (trace + DNSSEC) drill will securely trace from the root down.
140       If  the  optional  -k argument is given a genuine chain of trust can be
141       established.  [bla bla, Miek please add more]
