Prerequisites

• Subscription to NetAcuity for databases

Install the NetAcuity module

1. Get the NetAcuity databases. If this is a .tar.gz file, unzip it and place the files in a directory on your web server.

2. Install the NetAcuity module as follows, depending on your platform:

   apt install hapee-1.9r1-lb-netacuity

   or

   yum install hapee-1.9r1-lb-netacuity

Configure the NetAcuity module

1. In the global section of HAProxy's configuration file /etc/hapee-1.9r1/hapee-lb.conf, add the following lines: (see the section Global parameters below)

   module-load hapee-lb-netacuity.so
   netacuity-cache-size 2000000
   netacuity-debug 7
   netacuity-property-separator ,
   netacuity-load 04 /etc/haproxy/netacuity
   netacuity-update url 04 http://myserver.local:8000/netacuity xdelay 3m 5s 1s 1s  timeout 100ms  retries 3  checksum  hash  log
   netacuity-test-ipv4 /home/zaga/work/data/ipsc.txt 1000000

2. Add the netacuity-lookup-ipv4 and/or netacuity-lookup-ipv6 converters to make use of the data: (see the section Converters below)

   listen NetAcuity-module-test
       bind *:10080
       mode http
       server localhost 127.0.0.1:8000

Global parameters

The NetAcuity module accepts the following directives in the global section:

• netacuity-load <feature_code> <directory> (required): Specifies the local directory where you store NetAcuity files. The feature code depends on the type of database. For example, if you name your NetAcuity files na_04_01.db, na_04_02.db, etc., then set the feature code to 04.

• netacuity-update url <feature_code url> [delay <u> | xdelay <u s b r>] [timeout <t>] [retries <n>] [checksum] [hash] [log] [dontlog-normal] [param\*] (required): Enables the module to update databases over HTTP from a specified URL.

  Updating a database with a newer version invalidates any cached lookups (if using cache), unless you enable the checksum setting, and the new and old database contents are identical.

  We recommend that you host the unzipped file directory at this URL. This directive contains the following settings:

  url <feature_code url> (required)	Specifies URL for the database update. The feature code depends on the type of database. For example, if you name your NetAcuity files na_04_01.db, na_04_02.db, etc., then set the feature code to 04.
  delay <u>	<u> specifies the period between each attempt to download a new database version. The delay is a simplified version of the xdelay keyword.
  xdelay <u s b r>	Delay settings are defined as follows: <u> specifies the period between each attempt to download a new database version. Default: 5m <s> specifies the initial (first) download delay. Default: 5s <b> specifies the delay between the download of each element of the database. Default: 10s If the download fails, <r> determines the delay for the next attempt. Default: 30s If the new version of the database fails to download after three attempts, the module cancels the download until the next time interval specified by <u>. In this case, it discards the downloaded data.
  timeout <t>	Specifies the HTTP connection timeout for attempts to download a new database version. The value is in milliseconds by default, but you can set it to any other unit if you add it as a suffix to the number. Default: 5s.
  retries <n>	Specifies the number of retries to download a new NetAcuity database version. If unspecified, the global retries value applies. Default: 3
  checksum	If present, determines the use of the SHA1 control sum to verify that the content of the recently downloaded database is identical to the one already used. If they are identical, the module does not do a live-reload of the database, thereby preserving cache contents (if you use caching).
  hash	If present, enables authentication of downloaded data. Each upgraded file must have the associated file with a SHA1 checksum. The SHA1 checksum file has the extension .sha1. The typical way to create the SHA1 checksum file is: sha1sum file > file.sha1
  log	Specifies whether to log operation errors.
  dontlog-normal	Deactivates logging for successful updates.
  param*	Lists other server parameters; useful to configure special SSL features.

• netacuity-cache-size <number>: Specifies the size of the LRU cache used for lookups. The minimum size of 0 disables the cache. The maximum cache size is 10000000. Default: 0

• netacuity-debug <level>: Enables logging for unsuccessful IP address lookups, as well as for attempts to read unavailable fields from records of successfully looked up IP addresses.

• netacuity-test-ipv4 <filename> [rows]: If used, it allows loading IPv4 addresses from the input file. If you don't specify the number of rows, the module loads the entire file. Use this only when the module runs in debug mode; in normal use it has no significance.

Converters

The netacuity-lookup-ipv4 and netacuity-lookup-ipv6 converters search the IPv4 and IPv6 NetAcuity databases, respectively, for the value of the specified entity.

They can return several properties by specifying each element successively; in that case, the returned values are separated by commas.

The syntax for converters is as follows:

netacuity-lookup-ipv4(<prop>[,<prop>*])
netacuity-lookup-ipv6(<prop>[,<prop>*])

The maximum number of properties in one lookup is eight. Valid property types are:

• src-ip (Note: This property shows the IP address of the client in IPv6 format.)

• pulse-area-codes

• pulse-city

• pulse-city-code

• pulse-city-conf

• pulse-conn-speed

• pulse-conn-type

• pulse-continent-code

• pulse-country

• pulse-country-code

• pulse-country-conf

• pulse-gmt-offset

• pulse-in-dst

• pulse-internal-code

• pulse-latitude

• pulse-longitude

• pulse-metro-code

• pulse-postal-code

• pulse-postal-conf

• pulse-region

• pulse-region-code

• pulse-region-conf

• pulse-timezone-name

• pulse-two-letter-country
