It is specificly designed to be used with DNSSEC. +.PP +The name \fBdrill\fR is a pun on \fBdig\fR. With \fBdrill\fR you should be able +get even more information than with \fBdig\fR. +.PP +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. + +.PP +\fIname\fR +Ask for this name. + +.PP +\fI@server\fR +Send to query to this server. If not specified use the nameservers from +\fI/etc/resolv.conf\fR. + +.PP +\fItype\fR +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'. + +.PP +\fIclass\fR +Use this class when querying. + +.SH SAMPLE USAGE +\fBdrill mx miek.nl\fR +Show the MX records of the domain miek.nl + +.TP +\fBdrill -S jelte.nlnetlabs.nl\fR +Chase any signatures in the jelte.nlnetlab.nl domain. This option is +only available when ldns has been compiled with openssl-support. + +.TP +\fBdrill -TD www.example.com\fR +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. + +.TP +\fBdrill -s dnskey jelte.nlnetlabs.nl\fR +Show the DNSKEY record(s) for jelte.nlnetlabs.nl. For each found DNSKEY +record also print the DS record. + +.SH OPTIONS + +.TP +\fB\-D +Enable DNSSEC in the query. When querying for DNSSEC types (DNSKEY, RRSIG, +DS and NSEC) this is \fInot\fR automaticly enabled. + +.TP +\fB\-T +Trace \fIname\fR from the root down. When using this option the @server and +the type arguments are not used. + +.TP +\fB\-S +Chase the signature(s) of 'name' to a known key or as high up in +the tree as possible. + +.TP +\fB\-V \fIlevel\fR +Be more verbose. Set level to 5 to see the actual query that is sent. + +.TP +\fB\-Q +Quiet mode, this overrules -V. + +.TP +\fB\-f \fIfile\fR +Read the query from a file. The query must be dumped with -w. + +.TP +\fB\-i \fIfile\fR +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. + +.TP +\fB\-w \fIfile\fR +Write an answer packet to file. + +.TP +\fB\-q \fIfile\fR +Write the query packet to file. + +.TP +\fB\-v +Show drill's version. + +.TP +\fB\-h +Show a short help message. + +.SS QUERY OPTIONS + +.TP +\fB\-4 +Stay on ip4. Only send queries to ip4 enabled nameservers. + +.TP +\fB\-6 +Stay on ip6. Only send queries to ip6 enabled nameservers. + +.TP +\fB\-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. + +.TP +\fB\-b \fIsize\fR +Use size as the buffer size in the EDNS0 pseudo RR. + +.TP +\fB\-c \fIfile\fR +Use file instead of /etc/resolv.conf for nameserver configuration. + +.TP +\fB\-d \fIdomain\fR +When tracing (-T), start from this domain instead of the root. + +.TP +\fB\-t +Use TCP/IP when querying a server + +.TP +\fB\-k \fIkeyfile\fR +Use this file to read a (trusted) key from. When this options is +given \fBdrill\fR tries to validate the current answer with this +key. No chasing is done. When \fBdrill\fR is doing a secure trace, this +key will be used as trust anchor. Can contain a DNSKEY or a DS record. + +.TP +\fB\-o \fImnemonic\fR +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 \fBdrill\fR: + + 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: \fB-o CD\fR, will enable Checking Disabled, which instructs the +cache to not validate the answers it gives out. + +.TP +\fB\-p \fIport\fR +Use this port instead of the default of 53. + +.TP +\fB\-r \fIfile\fR +When tracing (-T), use file as a root servers hint file. + +.TP +\fB\-s +When encountering a DNSKEY print the equivalent DS also. + +.TP +\fB\-u +Use UDP when querying a server. This is the default. + +.TP +\fB\-w \fIfile\fR +write the answer to a file. The file will contain a hexadecimal dump +of the query. This can be used in conjunction with -f. + +.TP +\fB\-x +Do a reverse loopup. The type argument is not used, it is preset to PTR. + +.TP +\fB\-y \fI<name:key[:algo]>\fR +specify named base64 tsig key, and optional an algorithm (defaults to hmac-md5.sig-alg.reg.int) + +.TP +\fB\-z \fR +don't randomize the nameserver list before sending queries. + + +.SH AUTHOR +Jelte Jansen and Miek Gieben.
