# DNS Statistics Collector
|
||||
|
||||
[](https://sonarcloud.io/summary/new_code?id=dns-oarc%3Adsc) [](https://sonarcloud.io/summary/new_code?id=dns-oarc%3Adsc)
|
||||
|
||||
DNS Statistics Collector (DSC) is a tool used for collecting and exploring
|
||||
statistics from busy DNS servers. It can be set up to run on or near
|
||||
nameservers to generate aggregated data that can then be transported to
|
||||
central systems for processing, displaying and archiving.
|
||||
|
||||
Together with `dsc-datatool` the aggregated data can be furthur enriched
|
||||
and converted for import into for example InfluxDB which can then be
|
||||
accessed by Grafana for visualzation, see this wiki on how to set up that:
|
||||
- https://github.com/DNS-OARC/dsc-datatool/wiki/Setting-up-a-test-Grafana
|
||||
|
||||
DSC data transforming and enriching tool can be found here:
|
||||
- https://github.com/DNS-OARC/dsc-datatool
|
||||
|
||||
More information about DSC may be found here:
|
||||
- https://www.dns-oarc.net/tools/dsc
|
||||
- https://www.dns-oarc.net/oarc/data/dsc
|
||||
|
||||
Issues should be reported here:
|
||||
- https://github.com/DNS-OARC/dsc/issues
|
||||
|
||||
General support and discussion:
|
||||
- Mattermost: https://chat.dns-oarc.net/community/channels/oarc-software
|
||||
- mailing-list: https://lists.dns-oarc.net/mailman/listinfo/dsc
|
||||
|
||||
## Dependencies
|
||||
|
||||
`dsc` requires a couple of libraries beside a normal C compiling
|
||||
environment with autoconf, automake, libtool and pkgconfig.
|
||||
|
||||
`dsc` has a non-optional dependency on the PCAP library and optional
|
||||
dependency on the MaxMindDB library (for the `asn` and `country` indexer).
|
||||
|
||||
To install the dependencies under Debian/Ubuntu:
|
||||
```
|
||||
apt-get install -y libpcap-dev
|
||||
```
|
||||
|
||||
To install the dependencies under CentOS (with EPEL/PowerTools enabled):
|
||||
```
|
||||
yum install -y libpcap-devel
|
||||
```
|
||||
|
||||
To install the dependencies under FreeBSD 10+ using `pkg`:
|
||||
```
|
||||
pkg install -y libpcap
|
||||
```
|
||||
|
||||
NOTE: It is recommended to install the PCAP library from source/ports on
|
||||
OpenBSD since the bundled version is an older and modified version.
|
||||
|
||||
### DNSTAP support
|
||||
|
||||
To enable DNSTAP support, first install the necessary dependencies and
|
||||
then run `configure` with `--enable-dnstap`.
|
||||
|
||||
- Debian/Ubuntu: `apt-get install -y libdnswire-dev libuv1-dev`
|
||||
- CentOS: `yum install -y dnswire-devel libuv-devel`
|
||||
- FreeBSD: `pkg install -y libuv`
|
||||
- OpenBSD: `pkg_add libuv`
|
||||
|
||||
`dnswire` packages for Debian, Ubuntu and CentOS exists at
|
||||
[https://dev.dns-oarc.net/packages/](https://dev.dns-oarc.net/packages/),
|
||||
for other distributions please see
|
||||
[https://github.com/DNS-OARC/dnswire](https://github.com/DNS-OARC/dnswire).
|
||||
|
||||
## Building from source tarball
|
||||
|
||||
The [source tarball from DNS-OARC](https://www.dns-oarc.net/dsc/download)
|
||||
comes prepared with `configure`:
|
||||
|
||||
```
|
||||
tar zxvf dsc-version.tar.gz
|
||||
cd dsc-version
|
||||
./configure [options]
|
||||
make
|
||||
make install
|
||||
```
|
||||
|
||||
NOTE: If building fails on FreeBSD/OpenBSD, try adding these configure
|
||||
options: `--with-extra-cflags="-I /usr/local/include" --with-extra-ldflags="-L/usr/local/lib"`.
|
||||
|
||||
## Building from Git repository
|
||||
|
||||
If you are building `dsc` from it's Git repository you will first need
|
||||
to initiate the Git submodules that exists and later create autoconf/automake
|
||||
files, this will require a build environment with autoconf, automake, libtool
|
||||
and pkgconfig to be installed.
|
||||
|
||||
```
|
||||
git clone https://github.com/DNS-OARC/dsc.git
|
||||
cd dsc
|
||||
git submodule update --init
|
||||
./autogen.sh
|
||||
./configure [options]
|
||||
make
|
||||
make install
|
||||
```
|
||||
|
||||
NOTE: If building fails on FreeBSD/OpenBSD, try adding these configure
|
||||
options: `--with-extra-cflags="-I /usr/local/include" --with-extra-ldflags="-L/usr/local/lib"`.
|
||||
|
||||
## Puppet
|
||||
|
||||
John Bond at ICANN DNS Engineering team has developed a puppet module for DSC,
|
||||
the module and code can be found here:
|
||||
- https://forge.puppet.com/icann/dsc
|
||||

# Upgrade
|
||||
|
||||
This document contains the upgrade information between the major versions
|
||||
of DSC for the eventual breaking changes, please read CHANGES for the new
|
||||
features added.
|
||||
|
||||
# From dsc-201502251630 to v2.0.0
|
||||
|
||||
The `dsc-201502251630` was the last version release before the use of
|
||||
version numbering.
|
||||
|
||||
## Install Paths
|
||||
|
||||
Since the conform to FHS 3.0 paths have been changed but will only affect
|
||||
new installations where `configure` is not touched.
|
||||
|
||||
In previous version `INSTALLDIR` was set to `/usr/local/dsc`, this is now
|
||||
controlled by Automake and `configure` using `--prefix=DIR` or individual
|
||||
path options as below. See `configure --help` for information about default
|
||||
paths and how to control each of them.
|
||||
|
||||
- `upload-*` scripts was previously installed in `$INSTALLDIR/libexec`,
|
||||
is now installed in `$libexecdir/dsc`.
|
||||
- `dsc.conf.sample` was previously installed in `$INSTALLDIR/etc`, is now
|
||||
installed in `$sysconfdir/dsc`.
|
||||
- `dsc` was previously installed in `$INSTALLDIR/bin`, is not installed
|
||||
in `$bindir`.
|
||||
|
||||
## Data Files Path
|
||||
|
||||
The path to `dsc` data files that it output has been changed to
|
||||
`$localstatedir/lib/dsc` but only affects the path in `dsc.conf.sample`
|
||||
during installation. If you use an old configuration then `dsc` will
|
||||
store the data files in the same path as before. This can be controlled
|
||||
by `configure --with-data-dir=DIR`.
|
||||
|
||||
## Configuration
|
||||
|
||||
Dataset names have been made unique so `dsc` will not start if there are
|
||||
duplicates, you need to change the configuration so that all datasets
|
||||
are unique.
|
||||
|
||||
The following indexers have been removed since they are only aliases:
|
||||
- `cip4_addr`, use `client` instead.
|
||||
- `cip4_net`, use `client_subnet` instead.
|
||||
- `d0_bit`, use `do_bit` instead.
|
||||
|
||||
## Upload Scripts Deprecated
|
||||
|
||||
Altho the upload scripts are still installed they are now considered
|
||||
deprecated and will be removed in future versions.
|
||||
|
||||
The uploads scripts where constructed for the purpose of uploading `dsc`
|
||||
data to DNS-OARC and that is a very specific purpose that does not belong
|
||||
in a software repository. It can be replaced by instructions specific for
|
||||
each organization that needs to do it.
|
||||
|
||||
## PID File
|
||||
|
||||
The PID file is now locked and `dsc` will not start if another process has
|
||||
it locked.

## -MM, not -M (despite what the docs say). Also, it might not be
|
||||
## supported by the other compilers which use the 'gcc' depmode.

## This next piece of magic avoids the "deleted header file" problem.

## The problem is that when a header file which appears in a .P file

## is deleted, the dependency causes make to die (because there is

## typically no way to rebuild the header). We avoid this by adding
|

## dummy dependencies for each header file. Too bad gcc doesn't do
|

## this for us directly.
|

## Some versions of gcc put a space before the ':'. On the theory

## that the space means something, we add a space to the output as

## well. hp depmode also adds that space, but also prefixes the VPATH

# AX_APPEND_FLAG(FLAG, [FLAGS-VARIABLE])
|

#
|

# DESCRIPTION
|

#
|

# FLAG is appended to the FLAGS-VARIABLE shell variable, with a space

# added in between.
|

#
|
||||
# If FLAGS-VARIABLE is not specified, the current language's flags (e.g.

# CFLAGS) is used. FLAGS-VARIABLE is not changed if it already contains
|
||||
# FLAG. If FLAGS-VARIABLE is unset in the shell, it is set to exactly
|
||||
# FLAG.

dsc-psl-convert \- Convert Public Suffix List (PSL) to DSC TLD List
|
||||
.SH SYNOPSIS
|
||||
.B dsc-psl-convert
|
||||
[
|
||||
.B options
|
||||
]
|
||||
[
|
||||
.I PSL file
|
||||
]
|
||||
.SH DESCRIPTION
|
||||
Convert Public Suffix List (PSL) to DSC TLD List (stdout).
|
||||
|
||||
If the PSL is not specified then it will use the one installed on the system,
|
||||
for example on Debian/Ubuntu the package publicsuffix will be installed
|
||||
in /usr/share/publicsuffix.
|
||||
|
||||
If "-" is given as file then it will read from stdin.
|
||||
|
||||
The PSL can also be downloaded from https://publicsuffix.org/ .
|
||||
|
||||
The PSL will be converted to the TLD list format (see dsc.conf(5)) as follows:
|
||||
.RS
|
||||
.TP
|
||||
* Exceptions (!name) are ignored
|
||||
.TP
|
||||
* Singel label suffixes are ignored
|
||||
.TP
|
||||
* Wildcards (*.) are removed before processing
|
||||
.TP
|
||||
* All labels will be encoded in IDN/punycode
|
||||
.RE
|
||||
.SH OPTIONS
|
||||
.TP
|
||||
.B \-\-all
|
||||
Include all names found in the PSL file.
|
||||
Default is to stop after ICANN domains (===END ICANN DOMAINS===).
|
||||
.TP
|
||||
.B \-\-no\-skip\-idna\-err
|
||||
Report errors when trying to convert international domain names into ASCII
|
||||
(punycode).
|
||||
Default is to ignore these errors.
|
||||
.TP
|
||||
.BR \-h "|" \-\-help
|
||||
Show help and exit.
|
||||
.SH OUTPUT FORMAT
|
||||
The output format that is used for DSC's
|
||||
.I tld_list
|
||||
conf option is simply one line per suffix.
|
||||
It also supports commenting out an entry with #.
|
||||
|
||||
For example:
|
||||
|
||||
.EX
|
||||
co.uk
|
||||
net.au
|
||||
#net.cn
|
||||
.EE
|
||||
.SH EXAMPLE SETUP
|
||||
This example fetches the Public Suffix List and converts it in-place to
|
||||
a DSC TLD list, stores it in /etc/dsc and configures DSC to use that.
|
||||
|
||||
.EX
|
||||
wget -O - https://publicsuffix.org/list/public_suffix_list.dat | \\
|
||||
dsc-psl-convert - > /etc/dsc/tld.list
|
||||

.SH DESCRIPTION
|
||||
DNS Statistics Collector (\fIdsc\fR) is a tool used for collecting and
|
||||
exploring statistics from busy DNS servers.
|
||||
It can be set up to run on or near nameservers to generate aggregated data
|
||||
that can then be transported to central systems for processing, displaying
|
||||
and archiving.
|
||||
|
||||
Together with \fBdsc-datatool\fR the aggregated data can be furthur enriched
|
||||
and converted for import into for example InfluxDB which can then be
|
||||
accessed by Grafana for visualzation, see this wiki on how to set up that:

.SH KNOWN ISSUES
|
||||
This program and/or components uses
|
||||
.I select(2)
|
||||
to wait for packets and there may be an internal delay within that call
|
||||
during startup that results in missed packets.
|
||||
As a workaround, set
|
||||
.I pcap_thread_timeout
|
||||
( see
|
||||
.I dsc.conf(5)
|
||||
) to a relevant millisecond timeout with regards to the queries per second
|
||||
(QPS) received.
|
||||
For example if your receiving 10 QPS then you have 20 packets per second
|
||||
(PPS) and if spread out equally over a second you have a packet per 50 ms
|
||||
which you can use as timeout value.
|
||||
Since version 2.4.0 the default is 100 ms.
