banip: release 0.8.0 (nft rewrite)

Browse Source 
- complete rewrite of banIP to support nftables
- all sets are handled in a separate nft table/namespace 'banIP'
- for incoming blocking it uses the inet input hook, for outgoing blocking it uses the inet forward hook
- full IPv4 and IPv6 support
- supports nft atomic set loading
- supports blocking by ASN numbers and by iso country codes
- 42 preconfigured external feeds are available, plus local allow- and blocklist
- supports local allow- and blocklist (IPv4, IPv6, CIDR notation or domain names)
- auto-add the uplink subnet to the local allowlist
- provides a small background log monitor to ban unsuccessful login attempts in real-time
- the logterms for the log monitor service can be freely defined via regex
- auto-add unsuccessful LuCI, nginx, Asterisk or ssh login attempts to the local blocklist
- fast feed processing as they are handled in parallel as background jobs
- per feed it can be defined whether the input chain or the forward chain should be blocked (default: both chains)
- automatic blocklist backup & restore, the backups will be used in case of download errors or during startup
- automatically selects one of the following download utilities with ssl support: aria2c, curl, uclient-fetch or wget
- supports a 'allowlist only' mode, this option restricts internet access from/to a small number of secure websites/IPs
- provides comprehensive runtime information
- provides a detailed set report
- provides a set search engine for certain IPs
- feed parsing by fast & flexible regex rulesets
- minimal status & error logging to syslog, enable debug logging to receive more output
- procd based init system support (start/stop/restart/reload/status/report/search)
- procd network interface trigger support
- ability to add new banIP feeds on your own
- add a readme with all available options/feeds to customize your installation to your needs

# banIP - ban incoming and/or outgoing ip adresses via ipsets
# banIP - ban incoming and outgoing IP addresses/subnets via sets in nftables
## Description
IP address blocking is commonly used to protect against brute force attacks, prevent disruptive or unauthorized address(es) from access or it can be used to restrict access to or from a particular geographic area — for example.
IP address blocking is commonly used to protect against brute force attacks, prevent disruptive or unauthorized address(es) from access or it can be used to restrict access to or from a particular geographic area — for example. Further more banIP scans the log file via logread and bans IP addresses that make too many password failures, e.g. via ssh.
## Main Features
* Support of the following fully pre-configured domain blocklist sources (free for private usage, for commercial use please check their individual licenses)
* banIP supports the following fully pre-configured domain blocklist feeds (free for private usage, for commercial use please check their individual licenses).
**Please note:** the columns "INP" and "FWD" show for which chains the feeds are suitable in common scenarios, e.g. the first entry should be limited to forward chain - see the config options 'ban\_blockforward' and 'ban\_blockinput' below.

## Prerequisites
* [OpenWrt](https://openwrt.org), tested with the stable release series (21.02.x) and with the latest rolling snapshot releases. On turris devices it has been successfully tested with TurrisOS 5.2.x
<b>Please note:</b> Ancient OpenWrt releases like 18.06.x or 17.01.x are _not_ supported!
<b>Please note:</b> Devices with less than 128 MByte RAM are _not_ supported!
<b>Please note:</b> If you're updating from former banIP 0.3x please manually remove your config (/etc/config/banip) before you start!
* A download utility with SSL support: 'wget', 'uclient-fetch' with one of the 'libustream-*' ssl libraries, 'aria2c' or 'curl' is required
* A certificate store like 'ca-bundle', as banIP checks the validity of the SSL certificates of all download sites by default
* Optional E-Mail notification support: for E-Mail notifications you need to install and setup the additional 'msmtp' package
* **[OpenWrt](https://openwrt.org)**, latest stable release or a snapshot with nft/firewall 4 support
* a download utility with SSL support: 'wget', 'uclient-fetch' with one of the 'libustream-*' SSL libraries, 'aria2c' or 'curl' is required
* a certificate store like 'ca-bundle', as banIP checks the validity of the SSL certificates of all download sites by default
* for E-Mail notifications you need to install and setup the additional 'msmtp' package
**Please note the following:**
* Devices with less than 256Mb of RAM are **_not_** supported
* Any previous installation of banIP must be uninstalled, and the /etc/banip folder and the /etc/config/banip configuration file must be deleted (they are recreated when this version is installed)
* There is no LuCI frontend at this time
## Installation & Usage
* Update your local opkg repository (_opkg update_)
* Install 'banip' (_opkg install banip_). The banIP service is disabled by default
* Install the LuCI companion package 'luci-app-banip' (_opkg install luci-app-banip_)
* It's strongly recommended to use the LuCI frontend to easily configure all aspects of banIP, the application is located in LuCI under the 'Services' menu
* update your local opkg repository (_opkg update_)
* install banIP (_opkg install banip_) - the banIP service is disabled by default
* edit the config file '/etc/config/banip' and enable the service (set ban\_enabled to '1'), then add pre-configured feeds via 'ban\_feed' (see the config options below)
* start the service with '/etc/init.d/banip start' and check check everything is working by running '/etc/init.d/banip status'
## banIP CLI
* All important banIP functions are accessible via CLI as well.
<pre><code>
~# /etc/init.d/banip
## banIP CLI interface
* All important banIP functions are accessible via CLI. A LuCI frontend will be available in due course.

**black-/whitelist handling:**
banIP supports a local black & whitelist (IPv4, IPv6, CIDR notation or domain names), located by default in /etc/banip/banip.whitelist and /etc/banip/banip.blacklist.
Unsuccessful LuCI logins, suspicious nginx request or ssh login attempts via 'dropbear'/'sshd' could be tracked and automatically added to the local blacklist (see the 'ban_autoblacklist' option). Furthermore the uplink subnet could be automatically added to local whitelist (see 'ban_autowhitelist' option). The list behaviour could be further tweaked with different timeout and counter options (see the config options section above).
Last but not least, both lists also accept domain names as input to allow IP filtering based on these names. The corresponding IPs (IPv4 & IPv6) will be resolved in a detached background process and added to the IPsets. The detached name lookup takes place only during 'restart' or 'reload' action, 'start' and 'refresh' actions are using an auto-generated backup instead.
**whitelist-only mode:**
banIP supports a "whitelist only" mode. This option allows to restrict the internet access from/to a small number of secure websites/IPs, and block access from/to the rest of the internet. All IPs and Domains which are _not_ listed in the whitelist are blocked. Please note: suspend/resume does not work in this mode.
**Manually override the download options:**
By default banIP uses the following pre-configured download options:
* aria2c: <code>--timeout=20 --allow-overwrite=true --auto-file-renaming=false --log-level=warn --dir=/ -o</code>
* curl: <code>--connect-timeout 20 --silent --show-error --location -o</code>
* uclient-fetch: <code>--timeout=20 -O</code>
* wget: <code>--no-cache --no-cookies --max-redirect=0 --timeout=20 -O</code>
| ban_resolver | option | - | external resolver used for DNS lookups |

To use the email notification you have to install & configure the package 'msmtp'.
Looking for IP 221.228.105.173 on 2023-02-08 22:12:48
---
IP found in set oisdbasicv4
```
**allow-/blocklist handling**
banIP supports local allow and block lists (IPv4, IPv6, CIDR notation or domain names), located in /etc/banip/banip.allowlist and /etc/banip/banip.blocklist.
Unsuccessful login attempts or suspicious requests will be tracked and added to the local blocklist (see the 'ban\_autoblocklist' option). The blocklist behaviour can be further tweaked with the 'ban\_nftexpiry' option.
Furthermore the uplink subnet will be added to local allowlist (see 'ban\_autowallowlist' option).
Both lists also accept domain names as input to allow IP filtering based on these names. The corresponding IPs (IPv4 & IPv6) will be extracted in a detached background process and added to the sets.
**allowlist-only mode**
banIP supports an "allowlist only" mode. This option restricts the internet access from/to a small number of secure websites/IPs, and block access from/to the rest of the internet. All IPs and Domains which are _not_ listed in the allowlist are blocked.
**redirect Asterisk security logs to lodg/logread**
banIP only supports logfile scanning via logread, so to monitor attacks on Asterisk, its security log must be available via logread. To do this, edit '/etc/asterisk/logger.conf' and add the line 'syslog.local0 = security', then run 'asterisk -rx reload logger' to update the running Asterisk configuration.
**tweaks for low memory systems**
nftables supports the atomic loading of rules/sets/members, which is cool but unfortunately is also very memory intensive. To reduce the memory pressure on low memory systems (i.e. those with 256-512Mb RAM), you should optimize your configuration with the following options:
* point 'ban_reportdir' and 'ban_backupdir' to an external usb drive
* set 'ban_cores' to '1' (only useful on a multicore system) to force sequential feed processing
* set 'ban_splitsize' e.g. to '1000' to split the load of an external set after every 1000 lines/members
**tweak the download options**
By default banIP uses the following pre-configured download options:
```
* aria2c: --timeout=20 --allow-overwrite=true --auto-file-renaming=false --log-level=warn --dir=/ -o
* curl: --connect-timeout 20 --silent --show-error --location -o
* uclient-fetch: --timeout=20 -O
* wget: --no-cache --no-cookies --max-redirect=0 --timeout=20 -O
```
To override the default set 'ban_fetchparm' manually to your needs.
**send E-Mail notifications via 'msmtp'**
To use the email notification you must install & configure the package 'msmtp'.
Modify the file '/etc/msmtprc', e.g.:
<pre><code>
```
[...]
defaults
auth on
@ -360,39 +264,37 @@ syslog LOG_MAIL
account ban_notify
host smtp.gmail.com
port 587
from &lt;address&gt;@gmail.com
user &lt;gmail-user&gt;
password &lt;password&gt;
</code></pre>
Finally enable E-Mail support and add a valid E-Mail receiver address in LuCI.
**Edit, add new banIP sources:**
The banIP blocklist sources are stored in an external, compressed JSON file '/etc/banip/banip.sources.gz'.
This file is directly parsed in LuCI and accessible via CLI, just call _/etc/init.d/banip list_.
from <address>@gmail.com
user <gmail-user>
password <password>
```
Finally add a valid E-Mail receiver address.
To add new or edit existing sources extract the compressed JSON file _gunzip /etc/banip/banip.sources.gz_.
**add new banIP feeds**
The banIP blocklist feeds are stored in an external, compressed JSON file '/etc/banip/banip.feeds.gz'.
To add a new or edit an existing feed extract the compressed JSON file _gunzip /etc/banip/banip.feeds.gz_.
A valid JSON source object contains the following required information, e.g.:
<pre><code>
```
[...]

</code></pre>
Add an unique object name, make the required changes to 'url_4', 'rule_4' (and/or 'url_6', 'rule_6'), 'focus' and 'descurl' and finally compress the changed JSON file _gzip /etc/banip/banip.sources.gz_ to use the new source object in banIP.
<b>Please note:</b> if you're going to add new sources on your own, please make a copy of the default file and work with that copy further on, cause the default will be overwritten with every banIP update. To reference your copy set the option 'ban\_srcarc' which points by default to '/etc/banip/banip.sources.gz'
```
Add an unique object name, make the required changes and compress the changed JSON file finally with _gzip /etc/banip/banip.feeds_ to use the new feed file in banIP.
**Please note:** if you're going to add new feeds, **always** work with a copy of the default file; this file is always overwritten with every banIP update. To reference your own file set the option 'ban\_feedarchive' accordingly
