|
|
||||||
|
|
||||||
The licenses granted in Section 2.1 with respect to any Contribution

distributes such Contribution.
|
|
||||||
|
|
||||||
2.3. Limitations on Grant Scope
|
|
||||||
|
|
||||||
The licenses granted in this Section 2 are the only rights granted under
|
|
||||||
this License. No additional rights or licenses will be implied from the
|
|
||||||
distribution or licensing of Covered Software under this License.
|
|
||||||
Notwithstanding Section 2.1(b) above, no patent license is granted by a
|
|
||||||
Contributor:
|
|
||||||
|
|
||||||
(a) for any code that a Contributor has removed from Covered Software;
|
|
||||||
or

(b) for infringements caused by: (i) Your and any other third party's
|
|
||||||
modifications of Covered Software, or (ii) the combination of its
|
|
||||||
Contributions with other software (except as part of its Contributor
|
|
||||||
Version); or
|
|
||||||
|
|
||||||
(c) under Patent Claims infringed by Covered Software in the absence of
|
|
||||||
its Contributions.
|
|
||||||
|
|
||||||
This License does not grant any rights in the trademarks, service marks,
|
|
||||||
or logos of any Contributor (except as may be necessary to comply with
|
|
||||||
the notice requirements in Section 3.4).
|
|
||||||
|
|
||||||
2.4. Subsequent Licenses
|
|
||||||
|
|
||||||
No Contributor makes additional grants as a result of Your choice to
|
|
||||||
distribute the Covered Software under a subsequent version of this
|
|
||||||
License (see Section 10.2) or under the terms of a Secondary License (if
|
|
||||||
permitted under the terms of Section 3.3).
|
|
||||||
|
|
||||||
2.5. Representation
|
|
||||||
|
|
||||||
Each Contributor represents that the Contributor believes its
|
|
||||||
Contributions are its original creation(s) or it has sufficient rights
|
|
||||||
to grant the rights to its Contributions conveyed by this License.
|
|
||||||
|
|
||||||
2.6. Fair Use
|
|
||||||
|
|
||||||

|
||||||
equivalents.

|
||||||
|
|
||||||
2.7. Conditions
|
|
||||||
|
|
||||||
Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted

|
|
||||||
|
|
||||||
3. Responsibilities
|
|
||||||
-------------------
|
|
||||||
|
|
||||||
3.1. Distribution of Source Form
|
|
||||||
|
|
||||||
All distribution of Covered Software in Source Code Form, including any
|
|
||||||
Modifications that You create or to which You contribute, must be under
|
|
||||||
the terms of this License. You must inform recipients that the Source
|
|
||||||
Code Form of the Covered Software is governed by the terms of this
|
|
||||||
License, and how they can obtain a copy of this License. You may not
|
|
||||||
attempt to alter or restrict the recipients' rights in the Source Code
|
|
||||||
Form.
|
|
||||||
|
|
||||||
3.2. Distribution of Executable Form
|
|
||||||
|
|
||||||
If You distribute Covered Software in Executable Form then:
|
|
||||||
|
|
||||||
(a) such Covered Software must also be made available in Source Code
|
|
||||||
Form, as described in Section 3.1, and You must inform recipients of
|
|
||||||
the Executable Form how they can obtain a copy of such Source Code
|
|
||||||
Form by reasonable means in a timely manner, at a charge no more
|
|
||||||
than the cost of distribution to the recipient; and
|
|
||||||
|
|
||||||
(b) You may distribute such Executable Form under the terms of this
|
|
||||||
License, or sublicense it under different terms, provided that the
|
|
||||||
license for the Executable Form does not attempt to limit or alter
|
|
||||||
the recipients' rights in the Source Code Form under this License.
|
|
||||||
|
|
||||||
3.3. Distribution of a Larger Work
|
|
||||||
|
|
||||||
You may create and distribute a Larger Work under terms of Your choice,
|
|
||||||
provided that You also comply with the requirements of this License for
|
|
||||||
the Covered Software. If the Larger Work is a combination of Covered
|
|
||||||
Software with a work governed by one or more Secondary Licenses, and the
|
|
||||||
Covered Software is not Incompatible With Secondary Licenses, this
|
|
||||||
License permits You to additionally distribute such Covered Software
|
|
||||||
under the terms of such Secondary License(s), so that the recipient of
|
|
||||||
the Larger Work may, at their option, further distribute the Covered
|
|
||||||
Software under the terms of either this License or such Secondary
|
|
||||||
License(s).
|
|
||||||
|
|
||||||
3.4. Notices
|
|
||||||
|
|
||||||
You may not remove or alter the substance of any license notices
|
|
||||||
(including copyright notices, patent notices, disclaimers of warranty,
|
|
||||||
or limitations of liability) contained within the Source Code Form of
|
|
||||||
the Covered Software, except that You may alter any license notices to
|
|
||||||
the extent required to remedy known factual inaccuracies.
|
|
||||||
|
|
||||||
3.5. Application of Additional Terms
|
|
||||||
|
|
||||||
You may choose to offer, and to charge a fee for, warranty, support,
|
|
||||||
indemnity or liability obligations to one or more recipients of Covered
|
|
||||||
Software. However, You may do so only on Your own behalf, and not on
|
|
||||||
behalf of any Contributor. You must make it absolutely clear that any
|
|
||||||
such warranty, support, indemnity, or liability obligation is offered by
|
|
||||||
You alone, and You hereby agree to indemnify every Contributor for any
|
|
||||||
liability incurred by such Contributor as a result of warranty, support,
|
|
||||||
indemnity or liability terms You offer. You may include additional
|
|
||||||
disclaimers of warranty and limitations of liability specific to any
|
|
||||||
jurisdiction.
|
|
||||||
|
|
||||||
4. Inability to Comply Due to Statute or Regulation
|
|
||||||
---------------------------------------------------
|
|
||||||
|
|
||||||
If it is impossible for You to comply with any of the terms of this
|
|
||||||
License with respect to some or all of the Covered Software due to
|
|
||||||
statute, judicial order, or regulation then You must: (a) comply with
|
|
||||||
the terms of this License to the maximum extent possible; and (b)
|
|
||||||
describe the limitations and the code they affect. Such description must
|
|
||||||
be placed in a text file included with all distributions of the Covered
|
|
||||||
Software under this License. Except to the extent prohibited by statute
|
|
||||||
or regulation, such description must be sufficiently detailed for a
|
|
||||||
recipient of ordinary skill to be able to understand it.
|
|
||||||
|
|
||||||
5. Termination
|
|
||||||
--------------
|
|
||||||
|
|
||||||
5.1. The rights granted under this License will terminate automatically
|
|
||||||
if You fail to comply with any of its terms. However, if You become
|
|
||||||
compliant, then the rights granted under this License from a particular
|
|
||||||
Contributor are reinstated (a) provisionally, unless and until such
|
|
||||||
Contributor explicitly and finally terminates Your grants, and (b) on an
|
|
||||||
ongoing basis, if such Contributor fails to notify You of the
|
|
||||||
non-compliance by some reasonable means prior to 60 days after You have
|
|
||||||
come back into compliance. Moreover, Your grants from a particular
|
|
||||||
Contributor are reinstated on an ongoing basis if such Contributor
|
|
||||||
notifies You of the non-compliance by some reasonable means, this is the
|
|
||||||
first time You have received notice of non-compliance with this License
|
|
||||||
from such Contributor, and You become compliant prior to 30 days after
|
|
||||||
Your receipt of the notice.
|
|
||||||
|
|
||||||
5.2. If You initiate litigation against any entity by asserting a patent
|
|
||||||
infringement claim (excluding declaratory judgment actions,
|
|
||||||
counter-claims, and cross-claims) alleging that a Contributor Version
|
|
||||||
directly or indirectly infringes any patent, then the rights granted to
|
|
||||||
You by any and all Contributors for the Covered Software under Section
|
|
||||||
2.1 of this License shall terminate.
|
|
||||||
|
|
||||||
5.3. In the event of termination under Sections 5.1 or 5.2 above, all
|
|
||||||
end user license agreements (excluding distributors and resellers) which
|
|
||||||
have been validly granted by You or Your distributors under this License
|
|
||||||
prior to termination shall survive termination.

|
||||||
* 6. Disclaimer of Warranty *
|
|
||||||
* ------------------------- *
|
|
||||||
* *
|
|
||||||
* Covered Software is provided under this License on an "as is" *
|
|
||||||
* basis, without warranty of any kind, either expressed, implied, or *
|
|
||||||
* statutory, including, without limitation, warranties that the *
|
|
||||||
* Covered Software is free of defects, merchantable, fit for a *
|
|
||||||
* particular purpose or non-infringing. The entire risk as to the *
|
|
||||||
* quality and performance of the Covered Software is with You. *
|
|
||||||
* Should any Covered Software prove defective in any respect, You *
|
|
||||||
* (not any Contributor) assume the cost of any necessary servicing, *
|
|
||||||
* repair, or correction. This disclaimer of warranty constitutes an *
|
|
||||||
* essential part of this License. No use of any Covered Software is *
|
|
||||||
* authorized under this License except under this disclaimer. *

* 7. Limitation of Liability *
|
|
||||||
* -------------------------- *
|
|
||||||
* *
|
|
||||||
* Under no circumstances and under no legal theory, whether tort *
|
|
||||||
* (including negligence), contract, or otherwise, shall any *
|
|
||||||
* Contributor, or anyone who distributes Covered Software as *
|
|
||||||
* permitted above, be liable to You for any direct, indirect, *
|
|
||||||
* special, incidental, or consequential damages of any character *
|
|
||||||
* including, without limitation, damages for lost profits, loss of *
|
|
||||||
* goodwill, work stoppage, computer failure or malfunction, or any *
|
|
||||||
* and all other commercial damages or losses, even if such party *
|
|
||||||
* shall have been informed of the possibility of such damages. This *
|
|
||||||
* limitation of liability shall not apply to liability for death or *
|
|
||||||
* personal injury resulting from such party's negligence to the *
|
|
||||||
* extent applicable law prohibits such limitation. Some *
|
|
||||||
* jurisdictions do not allow the exclusion or limitation of *
|
|
||||||
* incidental or consequential damages, so this exclusion and *
|
|
||||||
* limitation may not apply to You. *
|

||||||
* *

|

|
|

8. Litigation
|
|
||||||
-------------
|
|
||||||
|
|
||||||
Any litigation relating to this License may be brought only in the
|
|
||||||
courts of a jurisdiction where the defendant maintains its principal
|
|
||||||
place of business and such litigation shall be governed by laws of that
|
|
||||||
jurisdiction, without reference to its conflict-of-law provisions.
|
|
||||||
Nothing in this Section shall prevent a party's ability to bring
|
|
||||||
cross-claims or counter-claims.
|
|
||||||
|
|
||||||
9. Miscellaneous
|
|
||||||
----------------
|
|
||||||
|
|
||||||
This License represents the complete agreement concerning the subject
|
|
||||||
matter hereof. If any provision of this License is held to be
|
|
||||||
unenforceable, such provision shall be reformed only to the extent
|
|
||||||
necessary to make it enforceable. Any law or regulation which provides
|
|
||||||
that the language of a contract shall be construed against the drafter
|
|
||||||
shall not be used to construe this License against a Contributor.
|
|
||||||
|
|
||||||

|
||||||
|
|
||||||
10.3. Modified Versions

create a new license for such software, you may create and use a
|
|
||||||
modified version of this License if you rename the license and remove
|
|
||||||
any references to the name of the license steward (except to note that

## Install

Install
|
||||||
|
-------
|
||||||
|
|
||||||
|
You can use git to install v1.x (and get updates) or just v1.0.x (and only get patches).
|
||||||
|
The API will not break until v2.
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# latest of v1.x
|
||||||
|
npm install 'git+https://git@git.daplie.com:Daplie/dns-suite#v1'
|
||||||
|
```
|
||||||
|
|
||||||
|
Don't have git? You can bow down to the gods of the centralized, monopolized, concentrated, dictatornet
|
||||||
|
(as we like to call it here at Daplie Labs):
|
||||||
|
|

|
|
||||||
|
|
||||||
### CLI Usage
|
You can work directly from `node_modules/dns-suite`:
|
||||||
|
|
||||||
When installed globally you can use these commands:
|
|
||||||
|
|
||||||
```
|
|
||||||
dns-parse.js </path/to/packet.dns.bin> [out.json] # parses a saved DNS packet to JSON
|
|
||||||
dns-pack.js </path/to/packet.dns.json> [out.bin] # packs a JSON DNS packet to binary
|
|
||||||
dns-test.js </path/to/packet.dns(.json|.bin)> # convert a packet back and forth to test reciprocity of the packer and parser
|
|
||||||
```
|
|
||||||
|
|
||||||
For **capturing packets** you should use [`dig.js`](https://git.coolaj86.com/coolaj86/dig.js#options) with the `--output` option.
|
|
||||||
It can capture mDNS as well. See <https://git.coolaj86.com/coolaj86/dig.js#options>.
|
|
||||||
|
|
||||||
You can also access them directly from `node_modules/dns-suite` in a project:
|
|
||||||
|
|
||||||
```bash
|
```bash
|
||||||
node node_modules/dns-suite/bin/dns-parse.js node_modules/dns-suite/samples/a-0.mdns.bin
|
pushd node_modules/dns-suite/
|
||||||
```
|
```
|
||||||
|
|
||||||
### Library API
|
Capture mDNS broadcast packets
|
||||||
|
|
||||||
- `DNSPacket.parse(nodeOrArrayBuffer)` returns json (as shown above)
|
```bash
|
||||||
- `DNSPacket.pack(packet)` returns ArrayBuffer (browser and node)
|
# example
|
||||||
- `DNSPacket.write(packet)` returns NodeBuffer (node only)
|
# node bin/mdns-capture.js <file-prefix>
|
||||||
|
node bin/mdns-capture.js mdns-test
|
||||||
|
```
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# in another terminal
|
||||||
|
dig @224.0.0.251 -p 5353 -t PTR _services._dns-sd._udp.local
|
||||||
|
```
|
||||||
|
|
||||||
|
Parsing a saved packet
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# example
|
||||||
|
# node bin/dns-parse.js </path/to/packet.dns.bin>
|
||||||
|
node bin/dns-parse.js samples/a-0.mdns.bin
|
||||||
|
```
|
||||||
|
|
||||||
|
You can also parse a saved packet from the `native-dns-packet` directory.
|
||||||
|
these test packets have the binary for each record type and what it's parsed output
|
||||||
|
should be.
|
||||||

||||||

How to add a new parser
|
||||||
|
-----------------------
|
||||||
```bash
|
|
||||||
# Install
|
|
||||||
npm install -g 'git+https://git.coolaj86.com/coolaj86/dig.js.git'
|
|
||||||
|
|
||||||
# Use with DNS
|
|
||||||
dig.js A coolaj86.com --output .
|
|
||||||
|
|
||||||
# Use with mDNS
|
|
||||||
dig.js --mdns PTR _services._dns-sd._udp.local --output .
|
|
||||||
```
|
|
||||||
|
|
||||||
# Resource Record Examples
|
|
||||||
|
|
||||||
- SOA
|
|
||||||
- NS
|
|
||||||
- A
|
|
||||||
- AAAA
|
|
||||||
- CNAME
|
|
||||||
- MX
|
|
||||||
- TXT
|
|
||||||
- SRV
|
|
||||||
- PTR
|
|
||||||
|
|
||||||
## SOA
|
|
||||||
|
|
||||||
I'm pretty sure that the SOA only goes in the `authority` section
|
|
||||||
(except when SOA is queried explicitly)
|
|
||||||
and that it's only given as a response to any empty set
|
|
||||||
(where `RCODE == NXDOMAIN`)
|
|
||||||
to affirm "yes, I am responsible for this domain but, no, I don't have a record for it".
|
|
||||||
|
|
||||||
If another nameserver has been delegated authority for a particular subdomain
|
|
||||||
a set of `NS` records should be returned instead.
|
|
||||||
|
|
||||||
```json
|
|
||||||
{
|
|
||||||

|

||||||

|
||||||

||||||

|
|
||||||
"minimum": 600
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
## NS
|
|
||||||
|
|
||||||
I'm also pretty sure that the NS only goes in the `authority` section
|
|
||||||
(except when NS is queried explicitly)
|
|
||||||
and that it's given as a successful response
|
|
||||||
(`RCODE == SUCCESS`)
|
|
||||||
to any query type
|
|
||||||
(`A` or `AAAA`, `MX`, `TXT`, or `SRV`)
|
|
||||||
where the answer sections is an empty set because the records in
|
|
||||||
question have been delegated to another nameserver.
|
|
||||||
|
|
||||||
```json
|
|
||||||
{
|
|
||||||
"name": "google.com",
|
|
||||||
"type": 2,
|
|
||||||
"typeName": "NS",
|
|
||||||
"class": 1,
|
|
||||||
"className": "IN",
|
|
||||||
"ttl": 82790,
|
|
||||||
"data": "ns3.google.com"
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
## A
|
|
||||||
|
|
||||||
The most common type of record. Returns the IPv4 address for a given domain.
|
|
||||||
|
|
||||||
```json
|
|
||||||
{
|
|
||||||
"name": "www.linode.com",
|
|
||||||
"type": 1,
|
|
||||||
"typeName": "A",
|
|
||||||
"class": 1,
|
|
||||||
"className": "IN",
|
|
||||||
"ttl": 291,
|
|
||||||
"address": "72.14.191.202"
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
## AAAA
|
|
||||||
|
|
||||||
Returns the IPv6 address for a given domain.
|
|
||||||
|
|
||||||
```json
|
|
||||||
{
|
|
||||||
"name": "irc6.geo.oftc.net",
|
|
||||||
"type": 28,
|
|
||||||
"typeName": "AAAA",
|
|
||||||
"class": 1,
|
|
||||||
"className": "IN",
|
|
||||||
"ttl": 59,
|
|
||||||
"address": "2607:f8f0:610:4000:211:11ff:fe1c:7bec"
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
## CNAME
|
|
||||||
|
|
||||||
The CNAME is used to look up the IP address for the given alias.
|
|
||||||
(the alias is often referred to incorrectly as a CNAME but it is, in fact, the alias)
|
|
||||||
|
|
||||||
```json
|
|
||||||
{
|
|
||||||
"name": "www.nodejs.org",
|
|
||||||
"type": 5,
|
|
||||||
"typeName": "CNAME",
|
|
||||||
"class": 1,
|
|
||||||
"className": "IN",
|
|
||||||
"ttl": 3600,
|
|
||||||
"data": "nodejs.org"
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
## MX
|
|
||||||
|
|
||||||
Mail Exchange Records show the alias that should be looked up to know where incoming mail should
|
|
||||||
be sent.
|
|
||||||
|
|
||||||
```json
|
|
||||||
{
|
|
||||||
"name": "microsoft.com",
|
|
||||||
"type": 15,
|
|
||||||
"typeName": "MX",
|
|
||||||
"class": 1,
|
|
||||||
"className": "IN",
|
|
||||||
"ttl": 197,
|
|
||||||
"priority": 10,
|
|
||||||
"exchange": "microsoft-com.mail.protection.outlook.com"
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
## TXT
|
|
||||||
|
|
||||||
Often used for outgoing mail validations, public keys, lots of arbitrary stuff.
|
|
||||||
|
|
||||||
```json
|
|
||||||
{
|
|
||||||
"name": "aol.com",
|
|
||||||
"type": 16,
|
|
||||||
"typeName": "TXT",
|
|
||||||
"class": 1,
|
|
||||||
"className": "IN",
|
|
||||||
"ttl": 1926,
|
|
||||||
"data": ["v=spf1 ptr:mx.aol.com ?all"]
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
## SRV
|
|
||||||
|
|
||||||
A way to associate a service with a port and other relevant information.
|
|
||||||
Used for federated / dencentralized protocols (like XMPP) and mDNS/DLNA/UPnP/DNS-SD type stuff.
|
|
||||||
|
|
||||||
```json
|
|
||||||
{
|
|
||||||
"name": "_xmpp-server._tcp.gmail.com",
|
|
||||||
"type": 33,
|
|
||||||
"typeName": "SRV",
|
|
||||||
"class": 1,
|
|
||||||
"className": "IN",
|
|
||||||
"ttl": 900,
|
|
||||||
"priority": 5,
|

"target": "xmpp-server.l.google.com"
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
## PTR
|
|
||||||
|
|
||||||
Used for mDNS/DNS-SD type discoveries and anti-spam reverse lookup verification for mail servers.
|
|
||||||
|
|
||||||
```json
|
|
||||||
{
|
|
||||||
"name": "_pdl-datastream._tcp.local",
|
|
||||||
"type": 12,
|
|

"typeName": "PTR",
|
|

"class": 1,
|

"className": "IN",
|
|
||||||
"ttl": 255,
|
|
