nginx proxy manager fail2ban
Today weve seen the top 5 causes for this error, and how to fix it. The steps outlined here make many assumptions about both your operating environment and Ackermann Function without Recursion or Stack. The name is used to name the chain, which is taken from the name of this jail (dovecot), port is taken from the port list, which are symbolic port names from /etc/services, and protocol and chain are taken from the global config, and not overridden for this specific jail. Setting up fail2ban is also a bit more advanced then firing up the nginx-proxy-manager container and using a UI to easily configure subdomains. Since most people don't want to risk running plex/jellyfin via cloudflare tunnels (or cloudflare proxy). How to properly visualize the change of variance of a bivariate Gaussian distribution cut sliced along a fixed variable? I have my fail2ban work : Do someone have any idea what I should do? Fail2ban can scan many different types of logs such as Nginx, Apache and ssh logs. But anytime having it either totally running on host or totally on Container for any software is best thing to do. Big question: How do I set this up correctly that I can't access my Webservices anymore when my IP is banned? Fail2ban already blocked several Chinese IPs because of this attempt, and I lowered to maxretry 0 and ban for one week. If you are using volumes and backing them up nightly you can easily move your npm container or rebuild it if necessary. +1 for both fail2ban and 2fa support. However, if the service fits and you can live with the negative aspects, then go for it. I am after this (as per my /etc/fail2ban/jail.local): Want to be generous and help support my channel? As you can see, NGINX works as proxy for the service and for the website and other services. I just cobbled the fail2ban "integration" together from various tutorials, with zero understanding of iptables or docker networking etc. If you do not use telegram notifications, you must remove the action For instance, for the Nginx authentication prompt, you can give incorrect credentials a number of times. Multiple applications/containers may need to have fail2ban, but only one instance can run on a system since it is playing with iptables rules. How would fail2ban work on a reverse proxy server? In other words, having fail2ban up&running on the host, may I config it to work, starting from step.2? nice tutorial but despite following almost everything my fail2ban status is different then the one is give in this tutorial as example. Should I be worried? Maybe someone in here has a solution for this. findtime = 60, NOTE: for docker to ban port need to use single port and option iptables -m conntrack --ctorigdstport --ctdir ORIGINAL, my personal opinion nginx-proxy-manager should be ONLY nginx-proxy-manager ; as with docker concept fail2ban and etc, etc, you can have as separate containers; better to have one good nginx-proxy-manager without mixing; jc21/nginx-proxy-manager made nice job. Or save yourself the headache and use cloudflare to block ips there. I do not want to comment on others instructions as the ones I posted are the only ones that ever worked for me. nginxproxymanager fail2ban for 401. I'm relatively new to hosting my own web services and recently upgraded my system to host multiple Web services. If youve ever done some proxying and see Fail2Ban complaining that a host is already banned, this is one cause. Would also love to see fail2ban, or in the meantime, if anyone has been able to get it working manually and can share their setup/script. 502 Bad Gateway in Nginx commonly occurs when Nginx runs as a reverse proxy, and is unable to connect to backend services. I cant find any information about what is exactly noproxy? Same thing for an FTP server or any other kind of servers running on the same machine. So please let this happen! Fail2Ban runs as root on this system, meaning I added roots SSH key to the authorized_keys of the proxy hosts user with iptables access, so that one can SSH into the other. [Init], maxretry = 3 Only solution is to integrate the fail2ban directly into to NPM container. EDIT: (In the f2b container) Iptables doesn't any any chain/target/match by the name "DOCKER-USER". These filter files will specify the patterns to look for within the Nginx logs. They just invade your physical home and take everything with them or spend some time to find a 0-day in one of your selfhosted exposed services to compromise your server. If you do not use PHP or any other language in conjunction with your web server, you can add this jail to ban those who request these types of resources: We can add a section called [nginx-badbots] to stop some known malicious bot request patterns: If you do not use Nginx to provide access to web content within users home directories, you can ban users who request these resources by adding an [nginx-nohome] jail: We should ban clients attempting to use our Nginx server as an open proxy. But there's no need for anyone to be up on a high horse about it. The only workaround I know for nginx to handle this is to work on tcp level. Generally Fail2Ban is then used to update firewall rules to reject the IP addresses for a specified amount of time, although any arbitrary other action (e.g. The supplied /etc/fail2ban/jail.conf file is the main provided resource for this. I've setup nginxproxymanager and would I'm confused). Forward port: LAN port number of your app/service. You signed in with another tab or window. On one hand, this project's goals was for the average joe to be able to easily use HTTPS for their incoming websites; not become a network security specialist. You'll also need to look up how to block http/https connections based on a set of ip addresses. privacy statement. However, we can create other chains, and one action on a rule is to jump to another chain and start evaluating it. It's the configuration of it that would be hard for the average joe. Endlessh is a wonderful little app that sits on the default ssh port and drags out random ssh responses until they time out to waste the script kiddie's time and then f2b bans them for a month. To get started, we need to adjust the configuration file that fail2ban uses to determine what application logs to monitor and what actions to take when offending entries are found. Not exposing anything and only using VPN. F2B is definitely a good improvement to be considered. The problem is that when i access my web services with an outside IP, for example like 99.99.99.99, my nginx proxy takes that request, wraps its own ip around it, for example 192.168.0.1, and then sends it to my webserver. Here is the sample error log from nginx 2017/10/18 06:55:51 [warn] 34604#34604: *1 upstream server temporarily disabled while connecting to upstream, client: , server: mygreat.server.com, request: "GET / HTTP/1.1", upstream: "https://:443/", host: "mygreat.server.com" to your account, Please consider fail2ban In your instructions, you mount the NPM files as /data/logs and mount it to /log/npm, but in this blog post, the author specifically mentions "Ensure that you properly bind mount the logs at /data/logs of your NPM reverse proxy into the Fail2ban docker container at /var/log/npm. I believe I have configured my firewall appropriately to drop any non-cloudflare external ips, but I just want a simple way to test that belief. I used following guides to finally come up with this: https://www.the-lazy-dev.com/en/install-fail2ban-with-docker/ - iptable commands etc .. Hope this helps some one like me who is trying to solve the issues they face with fail2ban and docker networks :). You can add this to the defaults, frontend, listen and backend sections of the HAProxy config. I switched away from that docker container actually simply because it wasn't up-to-date enough for me. The main one we care about right now is INPUT, which is checked on every packet a host receives. Otherwise, anyone that knows your WAN IP, can just directly communicate with your server and bypass Cloudflare. Every rule in the chain is checked from top to bottom, and when one matches, its applied. And to be more precise, it's not really NPM itself, but the services it is proxying. These will be found under the [DEFAULT] section within the file. Https encrypted traffic too I would say, right? But is the regex in the filter.d/npm-docker.conf good for this? Install_Nginx. Were not getting into any of the more advanced iptables stuff, were just doing standard filtering. Start by setting the mta directive.

Protecting your web sites and applications with firewall policies and restricting access to certain areas with password authentication is a great starting point to securing your system. Since its the proxy thats accepting the client connections, the actual server host, even if its logging system understands whats happening (say, with PROXY protocol) and logs the real clients IP address, even if Fail2Ban puts that IP into the iptables rules, since thats not the connecting IP, it means nothing. Isn't that just directing traffic to the appropriate service, which then handles any authentication and rejection? privacy statement. @kmanwar89 Yes! You may also have to adjust the config of HA. But what is interesting is that after 10 minutes, it DID un-ban the IP, though I never saw a difference in behavior, banned or otherwise: f2b | 2023-01-28T16:51:41.122149261Z 2023-01-28 11:51:41,121 fail2ban.actions [1]: NOTICE [npm-general-forceful-browsing] Unban 75.225.129.88.

So in all, TG notifications work, but banning does not. If you do not pay for a service then you are the product. Using Fail2ban behind a proxy requires additional configuration to block the IP address of offenders. Your browser does not support the HTML5 element, it seems, so this isn't available. Setting up fail2ban is also a bit more advanced then firing up the nginx-proxy-manager container and using a UI to easily configure subdomains. Authelia itself doesnt require a LDAP server or its own mysql database, it can use built in single file equivalents just fine for small personal installations. To properly block offenders, configure the proxy and Nginx to pass and receive the visitors IP address. But are you really worth to be hacked by nation state? I suppose you could run nginx with fail2ban and fwd to nginx proxy manager but sounds inefficient. Here are some ways to support: Patreon: https://dbte.ch/patreon PayPal: https://dbte.ch/paypal Ko-fi: https://dbte.ch/kofi/=========================================/Here's my Amazon Influencer Shop Link: https://dbte.ch/amazonshop I'd suggest blocking up ranges for china/Russia/India/ and Brazil. I am using the current LTS Ubuntu distribution 16.04 running in the cloud on a DigitalOcean Droplet. In my case, my folder is just called "npm" and is within the ~/services directory on my server, so I modified it to be (relative to the f2b compose file) ../npm/data/logs. Graphs are from LibreNMS. It works for me also. An action is usually simple. I already used Cloudflare for DNS management only since my initial registrar had some random limitations of adding subdomains. I think I have an issue. As v2 is not actively developed, just patched by the official author, it will not be added in v2 unless someone from the community implements it and opens a pull request. This worked for about 1 day. https://www.authelia.com/ Well, iptables is a shell command, meaning I need to find some way to send shell commands to a remote system.

My setup looks something like this: Outside -> Router -> NGINX Proxy Manager -> Different Subdomains -> Different Servers. PTIJ Should we be afraid of Artificial Intelligence? For some reason filter is not picking up failed attempts: Many thanks for this great article! If youd like to learn more about fail2ban, check out the following links: Thanks for learning with the DigitalOcean Community. Make sure the forward host is properly set with the correct http scheme and port. Setting up fail2ban can help alleviate this problem. This took several tries, mostly just restarting Fail2Ban, checking the logs to see what error it gave this time, correct it, manually clear any rules on the proxy host, and try again. Well occasionally send you account related emails. filter=npm-docker must be specified otherwise the filter is not applied, in my tests my ip is always found and then banned even for no reason. as in example? There are a few ways to do this. Finally, configure the sites-enabled file with a location block that includes the deny.conf file Fail2ban is writing to. We can create an [nginx-noscript] jail to ban clients that are searching for scripts on the website to execute and exploit. Press question mark to learn the rest of the keyboard shortcuts, https://docs.rackspace.com/support/how-to/block-an-ip-address-on-a-Linux-server/. We will use an Ubuntu 14.04 server. Im at a loss how anyone even considers, much less use Cloudflare tunnels. Once you have your MTA set up, you will have to adjust some additional settings within the [DEFAULT] section of the /etc/fail2ban/jail.local file. In this case, the action is proxy-iptables (which is what I called the file, proxy-iptables.conf), and everything after it in [ ] brackets are the parameters. I adapted and modified examples from this thread and I think I might have it working with current npm release + fail2ban in docker: run fail2ban in another container via https://github.com/crazy-max/docker-fail2ban However, though I can successfully now ban with it, I don't get notifications for bans and the logs don't show a successful ban. Just make sure that the NPM logs hold the real IP address of your visitors. According to https://www.home-assistant.io/docs/ecosystem/nginx/, it seems that you need to enable WebSocket support.

If npm will have it - why not; but i am using crazymax/fail2ban for this; more complexing docker, more possible mistakes; configs, etc; how will be or f2b integrated - should decide jc21. If you wish to apply this to all sections, add it to your default code block. WebWith the visitor IP addresses now being logged in Nginxs access and error logs, Fail2ban can be configured. LoadModule cloudflare_module. You can use the action_mw action to ban the client and send an email notification to your configured account with a whois report on the offending address.

People really need to learn to do stuff without cloudflare. Each jail within the configuration file is marked by a header containing the jail name in square brackets (every section but the [DEFAULT] section indicates a specific jails configuration). You'll also need to look up how to block http/https connections based on a set of ip addresses. Any guidance welcome. However, by default, its not without its drawbacks: Fail2Ban uses iptables to manage its bans, inserting a --reject-with icmp-port-unreachable rule for each banned host. The key defined by the proxy_cache_key directive usually consists of embedded variables (the default key, $scheme$proxy_host$request_uri, has three variables). edit: If a client makes more than maxretry attempts within the amount of time set by findtime, they will be banned: You can enable email notifications if you wish to receive mail whenever a ban takes place. @jc21 I guess I should have specified that I was referring to the docker container linked in the first post (unRAID). I want to try out this container in a production environment but am hesitant to do so without f2b baked in. When i used this command: sudo iptables -S some Ips also showed in the end, what does that means? Really, its simple. @arsaboo I use both ha and nextcloud (and other 13-ish services, including mail server) with n-p-m set up with fail2ban as I outlined above without any issue. If a law is new but its interpretation is vague, can the courts directly ask the drafters the intent and official interpretation of their law? to your account. It is sometimes a good idea to add your own IP address or network to the list of exceptions to avoid locking yourself out. @mastan30 I'm using cloudflare for all my exposed services and block IP in cloudflare using the API. What's the best 2FA / fail2ban with a reverse proxy : r/unRAID Each action is a script in action.d/ in the Fail2Ban configuration directory (/etc/fail2ban). Having f2b inside the npm container and pre-configured, similiar to the linuxio container, gives end users without experience in building jails and filters an extra layer of security. To learn more, see our tips on writing great answers. So I added the fallback_.log and the fallback-.log to my jali.d/npm-docker.local. Requests coming from the Internet will hit the proxy server (HAProxy), which analyzes the request and forwards it on to the appropriate server (Nginx). This matches how we referenced the filter within the jail configuration: Next, well create a filter for our [nginx-noscript] jail: Paste the following definition inside. I am behind Cloudflare and they actively protect against DoS, right? Update the local package index and install by typing: The fail2ban service is useful for protecting login entry points. Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. thanks. Maybe something like creating a shared directory on my proxy, let the webserver log onto that shared directory and then configure fail2ban on my proxy server to read those logs and block ips accordingly? This can be due to service crashes, network errors, configuration issues, and more. Additionally I tried what you said about adding the filter=npm-docker to my file in jail.d, however I observed this actually did not detect the IP's, so I removed that line. They will improve their service based on your free data and may also sell some insights like meta data and stuff as usual. Along banning failed attempts for n-p-m I also ban failed ssh log ins. For all we care about, a rules action is one of three things: When Fail2Ban matches enough log lines to trigger a ban, it executes an action. First, create a new jail: This jail will monitor Nginxs error log and perform the actions defined below: The ban action will take the IP address that matches the jail rules (based on max retry and findtime), prefix it with deny, and add it to the deny.conf file. So, is there a way to setup and detect failed login attemps of my webservices from my proxy server and if so, do youve got a hint? I have a question about @mastan30 solution: fail2ban-docker requires that fail2ban itself has to (or must not) be installed on the host machine (dont think, iti is in the container)? For reference this is my current config that bans ip on 3 different nginx-proxy-manager installations, I have joined the npm and fail2ban containers into 1 compose now: Apologies if this is offtopic, but if anyone doubts usefulness of adding f2b to npm or whether the method I used is working I'd like to share some statistics from my cloud server with exposed ssh and http(s) ports. On the other hand, f2b is easy to add to the docker container. In terminal: $ sudo apt install nginx Check to see if Nginx is running. It only takes a minute to sign up. Is there a (manual) way to use Nginx-proxy-manager reverse proxies in combination with Authelia 2FA? The DoS went straight away and my services and router stayed up. Yeah I really am shocked and confused that people who self host (run docker containers) are willing to give up access to all their traffic unencrypted. Can I implement this without using cloudflare tunneling? Big thing if you implement f2b, make sure it will pay attention to the forwarded-for IP. To do so, you will have to first set up an MTA on your server so that it can send out email. This textbox defaults to using Markdown to format your answer. If you are interested in protecting your Nginx server with fail2ban, you might already have a server set up and running. I needed the latest features such as the ability to forward HTTPS enabled sites. With both of those features added i think this solution would be ready for smb production environments. I've got a few things running behind nginx proxy manager and they all work because the basic http (s)://IP:port request locally auto loads the desired location. I would rank fail2ban as a primary concern and 2fa as a nice to have. They can and will hack you no matter whether you use Cloudflare or not. Have a question about this project? The next part is setting up various sites for NginX to proxy. Maybe recheck for login credentials and ensure your API token is correct. inside the jail definition file matches the path you mounted the logs inside the f2b container. These items set the general policy and can each be overridden in specific jails. So I assume you don't have docker installed or you do not use the host network for the fail2ban container. Each fail2ban jail operates by checking the logs written by a service for patterns which indicate failed attempts. I guess Ill stick to using swag until maybe one day it does. To influence multiple hosts, you need to write your own actions. in this file fail2ban/data/jail.d/npm-docker.local I have disabled firewalld, installed iptables, disabled (renamed) /jail.d/00-firewalld.conf file. Same for me, would be really great if it could added. This account should be configured with sudo privileges in order to issue administrative commands. The log shows "failed to execute ban jail" and "error banning" despite the ban actually happening (probably at the cloudflare level. Begin by running the following commands as a non-root user to Ask Question. What command did you issue, I'm assuming, from within the f2b container itself? How would fail2ban work on a reverse proxy server? After you have surpassed the limit, you should be banned and unable to access the site. The number of distinct words in a sentence.
