- # banIP - ban incoming and/or outgoing ip adresses via ipsets
-
- ## 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.
-
- ## Main Features
- * Support of the following fully pre-configured domain blocklist sources (free for private usage, for commercial use please check their individual licenses)

-
- * zero-conf like automatic installation & setup, usually no manual changes needed
- * automatically selects one of the following download utilities: aria2c, curl, uclient-fetch, wget
- * Really fast downloads & list processing as they are handled in parallel as background jobs in a configurable 'Download Queue'
- * full IPv4 and IPv6 support
- * ipsets (one per source) are used to ban a large number of IP addresses
- * supports blocking by ASN numbers
- * supports blocking by iso country codes
- * supports local white & blacklist (IPv4, IPv6 & CIDR notation), located by default in /etc/banip/banip.whitelist and /etc/banip/banip.blacklist
- * auto-add unsuccessful LuCI and ssh login attempts via 'dropbear' or 'sshd' to local blacklist (see 'ban_autoblacklist' option)
- * auto-add the uplink subnet to local whitelist (see 'ban_autowhitelist' option)
- * provides a small background log monitor to ban unsuccessful login attempts in real-time
- * per source configuration of SRC (incoming) and DST (outgoing)
- * integrated IPSet-Lookup
- * integrated RIPE-Lookup
- * blocklist source 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/refresh/status)
- * procd network interface trigger support
- * automatic blocklist backup & restore, they will be used in case of download errors or during startup
- * Provides comprehensive runtime information
- * Provides a detailed IPSet Report
- * Provides a powerful query function to quickly find blocked IPs/CIDR in banIP related IPSets
- * Provides an easily configurable blocklist update scheduler called 'Refresh Timer'
- * strong LuCI support
- * optional: add new banIP sources on your own
-
- ## Prerequisites
- * [OpenWrt](https://openwrt.org), tested with the stable release series (19.07.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> Older 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!
- * 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 the additional 'msmtp' package
-
- ## 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
-
- ## banIP CLI
- * All important banIP functions are accessible via CLI as well.
- <pre><code>
- ~# /etc/init.d/banip
- Syntax: /etc/init.d/banip [command]
-
- Available commands:
- start Start the service
- stop Stop the service
- restart Restart the service
- reload Reload configuration files (or restart if service does not implement reload)
- enable Enable service autostart
- disable Disable service autostart
- enabled Check if service is started on boot
- refresh Refresh ipsets without new list downloads
- suspend Suspend banIP processing
- resume Resume banIP processing
- query <IP> Query active banIP IPSets for a specific IP address
- report [<cli>|<mail>|<gen>|<json>] Print banIP related IPset statistics
- list [<add>|<add_asn>|<add_country>|<remove>|<remove_asn>|<remove_country>] <source(s)> List/Edit available sources
- timer [<add> <tasks> <hour> [<minute>] [<weekday>]]|[<remove> <line no.>] List/Edit cron update intervals
- version Print version information
- running Check if service is running
- status Service status
- trace Start with syscall trace
- </code></pre>
-

- </code></pre>
-
- **Enable E-Mail notification via 'msmtp':**
- To use the email notification you have to install & configure the package 'msmtp'.
- Modify the file '/etc/msmtprc', e.g.:
- <pre><code>
- [...]
- defaults
- auth on
- tls on
- tls_certcheck off
- timeout 5
- syslog LOG_MAIL
- [...]
- account ban_notify
- host smtp.gmail.com
- port 587
- from <address>k@gmail.com
- user <gmail-user>
- password <password>
- </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_.
-
- To add new or edit existing sources extract the compressed JSON file _gunzip /etc/banip/banip.sources.gz_.
- A valid JSON source object contains the following required information, e.g.:
- <pre><code>
- [...]
- "tor": {
- "url_4": "https://lists.fissionrelays.net/tor/exits-ipv4.txt",
- "url_6": "https://lists.fissionrelays.net/tor/exits-ipv6.txt",
- "rule_4": "/^(([0-9]{1,3}\\.){3}(1?[0-9][0-9]?|2[0-4][0-9]|25[0-5])(\\/(1?[0-9]|2?[0-9]|3?[0-2]))?)([[:space:]]|$)/{print \"add tor_4 \"$1}",
- "rule_6": "/^(([0-9A-f]{0,4}:){1,7}[0-9A-f]{0,4}:?(\\/(1?[0-2][0-8]|[0-9][0-9]))?)([[:space:]]|$)/{print \"add tor_6 \"$1}",
- "focus": "Tor exit nodes",
- "descurl": "https://fissionrelays.net/lists"
- },
- [...]
- </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'
-
- ## Support
- Please join the banIP discussion in this [forum thread](https://forum.openwrt.org/t/banip-support-thread/16985) or contact me by mail <dev@brenken.org>
-
- ## Removal
- * stop all banIP related services with _/etc/init.d/banip stop_
- * optional: remove the banip package (_opkg remove banip_)
-
- Have fun!
- Dirk
