I have two feature requests.
1. Allow an option to automatically put something when a user makes a thread or reply with no text. 2chan does this and replaces all no text posts with キタ━━━(゚∀゚)━━━!!.
2. Allow an option to have tripcodes with predefined outputs.

LynxChan Installation Tutorial

This is for debian.

Pre-install: Make sure you've created a user account with sudo rights, and use it for the rest of the tutorial. Do not run lynxchan on the root account.

1. Install nodejs

curl -sL | sudo -E bash -
sudo apt-get install -y nodejs
sudo apt-get install -y build-essential

2. Install Mongodb
sudo apt-key adv --keyserver hkp:// --recv EA312927
echo "deb wheezy/mongodb-org/3.2 main" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.2.list
sudo apt-get update
sudo apt-get install -y mongodb-org

3. Install imagemagick
sudo apt-get install imagemagick

4. Install ffmpeg
sudo echo deb testing main non-free \
sudo apt-get update
sudo apt-get install deb-multimedia-keyring
sudo apt-get update
sudo apt-get install ffmpeg

5. Clone lynxchan into your home folder
sudo apt-get install git
git clone

6. set up lynxchan
cd LynxChan/aux
Continue through it, I recommend installing the default front-end at first.

7. run the root setup so 'lynxchan' becomes a command
sudo ./

8. run lynxchan for the first time


ctrl c to close it

Part 2: Setting up a different front-end
You can either edit the current fe or get another one. Check out the list here.

1. Find the fe that you want
cd LynxChan/src
git clone 'the one you want'

2. Create the root account
lynxchan -ca -l login -p pass -gr 0
where login and pass are the login and password of your choice

3. run lynxchan

4. Head into your account. The default port is 8080
so localhost:8080 or ipaddress:8080 in your web browser

login with your newly created root account

5. head into localhost:8080/globalSettings.html
change a bunch of settings, but mostly change the fe to the folder of the desired fe.
example, if you cloned freechMinimalism, change the 'fe' part to 'freechMinimalism'

6. Save, the stop the engine and rebuild
lynxchan -r

Running lynxchan through nginx reverse web proxy

1. install nginx
sudo apt-get install nginx

2. remove apache2/stop apache2
to remove:
sudo service apache2 stop
sudo apt-get remove apache2
sudo apt-get autoremove

to stop:
sudo service apache2 stop

3. change the conf files for nginx
cd /etc/nginx/sites-a*

paste this
server {
listen 80;
server_name localhost;

location / {
proxy_pass http://localhost:8080;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
proxy_set_header X-Forwarded-For $remote_addr;

link it

ln -s /etc/nginx/sites-available/ /etc/nginx/sites-available/

delet the old config
cd /etc/nginx/sites-e*
rm -Rf default

start lynxchan as a service, then start nginx
sudo service nginx start
sudo service lynxchan start

access it from your web browser


Tell me if you want a tutorial for nginx, it's simple though just google it

A GUI proposition

I noticed you're developing a "fast" backend for an imageboard.
I'm a developer of a general-purpose GUI for an abstract imageboard.
Have a look at integration:
The project is hosted on GitHub:
If you're interested I could add support for `lynxchan` in that GUI.

Torilauta (most popular LynxChan instance ever?)

Torilauta ("market board") is a Finnish darknet imageboard forked from LynxChan 1.8.0 in November 2017. Stats show nearly 3 million posts, which is quite an accomplishment in less than 2 years especially considering that the population of Finland is only ~5.5 million and posting from abroad is prohibited. The main purpose of Torilauta seems to be selling & buying drugs in F2F (face-to-face) fashion on the streets of major Finland cities (each city having its own subboard).

Any thoughts and feelings? In particular, Stephen do you approve this use of LynxChan? Probably thousands of Finnish kids are addicted to drugs because of the imageboard you have created. Shame on you. Absolute degeneracy.

I have two questions.

1 - How does Lynxchan generate insecure tripcodes? I would like to make a custom tripcode generator like trip explorer.

2 - Can I lower my bandwidth consumption by using Nginx as a reverse proxy and having it gzip static files?

JS compile into a single file and minify? vichan has this and it's quite useful for reducing requests to the server

R: 1 / I: 0 / P: 3

So why doesn't "Delete posts by IP" automatically delete everything out of media management?
I think the de-duplicator itself is an unnecessary component. Even on sites without one, the file size never gets extremely intensive.
>4chan stats: Active Content: 1108 GB
Currently all the de-duplicator accomplishes is the following:
1) Produce odd filenames instead of standard UNIX timestamp filenames, like 8ch
2) Increase burden and complexity of moderation by adding another layer of shit you have to do just to get files to go away
3) Introduces possibility for administrator to "forget" about illegal content -- Content they deleted or deleted by IP would be retained in media management (and still entirely accessible on server to anyone with the URL, making it possible for a less-than-knowledgeable administrator to become an unknowing CP upload site.)

Should the file de-duplicator be removed entirely? I'd like to get your opinion.
Removing it would simplify moderation and make filenames more recognizable and standard.

being a cheap bastard

i like how lynxchan is meant to save people shitloads of money! with certbot and letsencrypt ssl , this money saving concept should be extended to ssl though!!! built in ssl is no longer necessary with free letsencrypt options. also, it costs money tonget the two required cert files. so im running lynxchan on ubuntu, from here to use letsencrypt i install nginx, then delete apache, then set up the sal cert with letsencrypt, right? As a feature request, maybe have it more user friendly tonuse letsencrypt? thanks !! i spend my money on coke and whores so saving money on ssl certs should be at least 3 more blow jobs from whores per week.

Prevent XSS ! Context Based Encoding
Cross Site Scripting (XSS) is one of the most common but ignored types of attacks. Since Node.js is implemented with JavaScript, there is high-risk of developers introducing XSS vulnerabilities in the code. Output encoding is one of the best ways to prevent XSS attacks. Most view engines such as Jade provides built-in encoding mechanisms. But most important thing is that you should use appropriate encoding to based on the context. Following are some situations that you should use context specific encoding.

URL encode parameters which are appended as url parameters. URL encoding can be done using encodeURI() and encodeURIComponent()javascript built-in methods.
HTML encode parameters which are displayed in HTML. HTML encoding is provided by view engines such as jade as well as frontend frameworks like Angularjs. You also can explicitly do it from server side using htmlencode npm module.
CSS encode parameters which are used in element styles

Lets talk about IP's. Okay so where the fuck on lynxchan do you see someone's ip? Even logged in as root, i never see my ip or any posters ip. I notice settings about ip, but never seen an ip.

not sure if there's a general suggestions thread but

one of the only real feature I prefer on vichan over lynx is the fact that you can paste a picture from your clipboard into the post. it seems to work on some modern social media shit. it can save a lot of time for the user but not sure if that would jibe with what you're trying to do or if it would be a priority.

Three things:

1. Are you able to bumplock threads in the latest LynxChan version? I know it's not possible in 2.0.1.
2. Stop requiring users to login to IRC to be able to join #LynxChan, that's retarded.
3. Enable TOR for this chan. It's annoying to have to enable a VPN in order to post anonymously.

2.2 breaking api changes

On 2.2 the json api features were merged into the form api and removed afterwards.
So not only the json input was removed, bu also the json output of the form api was remade. The refactoring is finished and penumbra has been adapted.

2.2 is scheduled to be released on march of 2019.

Lynxchan Docker

I'm a noob with docker, only know how to run images them not make them.

Does anyone already have, or want to make, lynxchan for docker? Either an all in one, or lynxchan in one that links to a separate mongodb image?
That would be sweet.
