I'm trying to run Mercure on my Raspbian.
First :
I tried with mercure-legacy_0.13.0_Linux_armv6.tar.gz using the following command to run mercure
JWT_KEY='example'; ADDR='localhost:3000'; DEMO='1'; ALLOW_ANO NYMOUS='1'; CORS_ALLOWED_ORIGINS='*'; PUBLISH_ALLOWED_ORIGINS='*'; PUBLISHER_JWT_KEY='example' ./mercure run
It returns :
"msg":"Unexpected error","error":"listen tcp :80: bind: permission denied"
Second : I tried with mercure_0.13.0_Linux_armv6.tar.gz using the following command to run Mercure
MERCURE_PUBLISHER_JWT_KEY='!ChangeMe!' MERCURE_SUBSCRIBER_JWT _KEY='!ChangeMe!' ./mercure run
Caddy file :
{
{$GLOBAL_OPTIONS}
}
{
auto_https off
}
{$SERVER_NAME:localhost}
log
route {
encode zstd gzip
mercure {
# Transport to use (default to Bolt)
transport_url {$MERCURE_TRANSPORT_URL:bolt://mercure.db}
# Publisher JWT key
publisher_jwt {env.MERCURE_PUBLISHER_JWT_KEY} {env.MERCURE_PUBLISHER_JWT_ALG}
# Subscriber JWT key
subscriber_jwt {env.MERCURE_SUBSCRIBER_JWT_KEY} {env.MERCURE_SUBSCRIBER_JWT_ALG}
# Extra directives
{$MERCURE_EXTRA_DIRECTIVES}
}
respond /healthz 200
respond "Not Found" 404
}
It returns :
run: loading initial config: loading new config: http app module: start: tcp: listening on :443: listen tcp :443: bind: permission denied
Can anyone provide a solution : I intend to host my symfony project on a web server using apache2 on the same Raspberrry
I don't know this specific application, but your error message:
listen tcp :80: bind: permission denied
could be related with restriction for ports 80 and 443 (second message) - non-root user cannot use ports lower than 1024 on standard Linux configuration. Try to use different port or (if you don't care about security - i.e. local hobby project) run app as root.
Keep in mind that you can run Nginx as reverse proxy, so you can run your app on any high port (like 3000) on standard user.
it's a rights issue with your user.
Try with sudo, it should work.
I am getting 404 accesing to https://my-dmain/ui/. If I try to access to https://my-dmain/artifactory it redirects to https://my-dmain/ui/ with 404. No log errors, only one warning:

Just to confirm it, can you try to access the Artifactory using the server IP and port, like HTTP://1.2.3.4:8082? If you are able to access the Artifactory UI using the server IP and Port, I believe you need to tweak the reverse proxy being used.
Your problem is that with Artifactory 7.x the reverse proxy configuration is different. In this KB article you can find a working NGINX configuration.
One easy way to generate such configuration is to bypass your reverse proxy and go to Artifactory directly, there in the UI you will be able to log in, head to HTTP settings, and generate a new Apache or NGINX config.
I have a web app running on machine with ip : 172.10.10.10.
The basic API call exposed by this app is : GET - http://172.10.10.10
and it will return a response as OK.
On another machine I added an entry in /etc/hosts file as below.
172.10.10.10 webserver1.com
With this the ping command is resolved successfully. e.g. : ping webserver1.com
Now I want to resolve the curl command as well.
e.g. : curl http://webserver1.com
Result : curl: (6) Could not resolve host: webserver1.com
How to achieve this for curl command with http url?
You can setup a DNS server and point your IP in /etc/resolv.conf
There are many options out there in marker ( paid / free ) for a Local DSN Server dockerized and non-dockerized too.
an nginx 1.14.0 site configuration has a number of domains pointing to a rails application.
server_name testing1.site.com testing2.site.com www.site.com testing1.site2.com testing2.site2.com www.site2.com;
Each of these domains is serving up properly, and have an associated certificate.
Adding these server names (on a single line)
server_name testing1.site.com testing2.site.com www.site.com testing1.site2.com testing2.site2.com www.site2.com
iwantthis.com www.iwantthis.com;
then
sudo nginx -t
runs properly and
sudo service nginx restart
without hiccups. Then, extending the certificate to the 2 new domains (via letsencrypt) passes the test of having the domain specified in a server block. Pinging the domains confirms the local DNS server is synched up.
Yet browser calls return a 404 error (the version of nginx shown is correct).
What is a possible source of this non routing and how can one test nginx's response for a specific domain request?
From previous versions of the question, there is this: Browse website with ip address rather than localhost, which outlines pretty much what I've done so far...I've got the local IP working. Then I found ngrok, and apparently I don't need to connect via the IP.
What I am trying to do is expose my website running on localhost to the internet. I found a tool that will do this: ngrok.
Running the website in visual studio, the website starts up on localhost/port#. I run the command "ngrok http port#" in the command line. Everything seems to start up fine. I generate a couple of URLs, and the ngrok inspection url (localhost:4040) works.
The only problem is that when I go to the generated URLs, I get an HTTP error 400: bad request invalid hostname. This is a different error than when I run "ngrok http wrongport#", which is a host not found error...so I think something good is happening. I just can't tell what...
Is there a step I am missing in exposing my site to the internet via the tunneling service? If there is, I can't find it in the ngrok documentation.
Troubleshot this issue with ngrok. In the words of inconshrevable, some applications get angry when they see a different host header than expected.
Running the following command should fix the problem:
ngrok http [port] --host-header="localhost:[port]"
Depending on the version, you may also want to try:
ngrok http [port] --host-header="localhost:[port]"
Following command will fix the issue
ngrok http -host-header=localhost 8080
This didn't work for me.
you could do the following:
For IIS Express
In VS 2015:
Go to the .vs\config\applicationhost.config folder in your project
In VS 2013 and earlier:
Go to %USERPROFILE%\My Documents\IISExpress\config\applicationhost.config
Find the binding that says:
<binding protocol="http" bindingInformation="*:5219:localhost" />
For me it was a project running on port 5219
change it to
<binding protocol="http" bindingInformation="*:5219:" />
IIS Express will now accept all incoming connections on that port.
Disadvantage: you need to run IIS Express as admin.
or you could rewrite the host header in Ngrok:
ngrok.exe http -host-header=rewrite localhost:5219
For https this works:
ngrok http https://localhost:<PORT> --host-header="localhost:<PORT>"
UPDATED COMMAND FOR LATEST VERSION
Tested with: (Windows) (ngrok v3.0.5)
Use -- instead of -
ngrok http --host-header=localhost 8080
The simplest thing for me was using iisexpress-proxy + ngrok.
First I install iisexpress-proxy globally with npm
npm install -g iisexpress-proxy
Then I proxy my localhost with it. Say for instance my site is running on 3003.
iisexpress-proxy 3003 to 12345 where 12345 is the new http port I want to proxy to.
Then I can run ngrok on it.
./ngrok.exe http 12345
It just works! 😃
But I think it works only with http. Right now I don't use https to test, but even if it works, usually it's a lot of work as always.
For https this works:
ngrok http https://localhost:<PORT> --host-header="localhost:<PORT>"
Try with different locations from the Global infrastructure > Locations
ngrok http -region eu 8080
You can make a request and view any traffic passing through your tunnel using the ngrok traffic inspector at http://localhost:4040.
OR in command line
ngrok http -region eu 8080 --log=stdout
If one region fails then try with another.
ngrok runs tunnel servers in datacenters around the world. The location of the datacenter within a given region may change without notice (e.g. the European servers may move from Frankfurt to London).
us - United States (Ohio)
eu - Europe (Frankfurt)
ap - Asia/Pacific (Singapore)
au - Australia (Sydney)
sa - South America (Sao Paulo)
jp - Japan (Tokyo)
in - India (Mumbai)
First open ngrok configuration YAML file, run from terminal:
ngrok config edit
Example of yaml for localhost setup (client & server):
version: "2"
authtoken: {YOUR_AUTH_TOKEN_FROM_NGROK_WEBSITE}
tunnels:
client:
addr: 3000
proto: http
host_header: localhost
server:
addr: 4000
proto: http
host_header: localhost
Save the config file based on your client and server ports and run the following command:
ngrok start --all
This will make ngrok open a tunnel for all the configurations declared in the yaml file
Had IIS Express .net web API, had installed NGROK in docker (windows as a host)
Had "Bad Request" error, the next command worked for me:
docker run -it -e NGROK_AUTHTOKEN=<token> ngrok/ngrok --host-header=localhost:21852 http host.docker.internal:21852
As I understood later, --host-header needed because IIS Express refuses all requests from outside (must be "localhost:port
"), host.docker.internal I've used instead of localhost, because NGROK was running inside docker, while IIS Express was running on a windows host.
I had the same issue and used the following solution:
Make sure your application binding in your IIS is set to All Unassigned IP address
Run ngrok HTTP 127.0.0.1:173 --region=eu --hostname=yourcustomdomain.eu.ngrok.io
That's it. Works perfectly. This solution is also for paid pro accounts
Steps.
Run command on your console from ngrok.exe directory . ngrok http
port i.e ngrok http 80 https://www.screencast.com/t/oyuEPlR6Z Set
Ngrok url to your app .
It will create a tunnel to your application.
Thanks .
