|-t||If this is present, the following argument is the askmara timeout, in seconds. Note that askmara can not both have a user-defined timeout and verbose output.|
|-v||If this is set, askmara will verbosely output the complete reply that the server sent. Note that this verbose output is not csv2-compatible.|
|-n||If this is set, askmara, when sending out a query, will not request DNS recursion; in other words, askmara will request that the remote DNS server not contact other DNS servers to answer the query in question.|
|dns record to be queried. The query has two sections: The type of record we desire, and the hostname we want this record for.|
|The type of query can have two forms: A one-letter mnemonic, or a numeric rtype followed by a colon. This is immediately concatenated by the full name of the host name we wish to look up.|
|For example, to ask for the IP of example.com., we can use the one-letter mnemonic, in the form Aexample.com., or we can use the numeric RR followed by a colon, giving the query 1:example.com. (since A has the record type of one). Note that the query name needs the trailing dot at the end.|
|Askmara supports a handful one-letter mnemonics, as follows:|
|A signifies a request for an A (ipv4 address) RR|
|N signifies a NS RR|
|C signifies that we are asking for a CNAME RR|
|S signifies that we want a SOA RR|
|P signifies that we want a PTR RR|
|@ signifies that we mant a MX RR|
|T signifies that we want a TXT RR|
|Z signifies that we want to ask for all RRs.|
|IP address of the dns server to be queried. If no server is given, askmara will query 127.0.0.1.|
Asking the server with the ip 127.0.0.1 for the IP address of example.com:
Asking the server with the ip 184.108.40.206 for the IP address of example.com:
askmara Aexample.com. 220.127.116.11
Asking the server with the ip address 127.0.0.1 for the IP address of example.com, using the rr_number:query format:
Asking the server with the ip address 127.0.0.1 for a SRV record. In particular, we ask for the "http over tcp" service for example.net. Since askmara doesnt have a mnemonic for SRV record types, we use the numeric code (33 for SRV):
Asking the server with the ip address 127.0.0.1 for the AAAA (ipv6 ip) record for example.net:
Note that the output will be a raw DNS packet in both the SRV and AAAA examples.
When askmara is asked for an SOA record, the output of askmara closely resembles the format of a csv2 file, but can not be parsed as a csv2 file without modification.
askmara outputs multi-chunk ("character-string") TXT records incorrectly (it only outputs the first chunk).
