I have a site on node js and Grunt.
Son when in my terminal I run "grunt serve:dist" it publishes me the site on 127.0.0.1:9000
Now I want to publish this to the net, with no-ip.org
Here's what I did:
Opened ports on my router:
9000 9000 TCP/IP 192.0.1.11
linking no-ip to my router
disabling mac firewall
but either I go on a browser and do xxx.xxx.xxx.xxx:9000 or mydomain.noip.me:9000 I don't see my website!
Make sure when you call listen(port, ip) in your code that you specify "0.0.0.0" as the IP, meaning "all IP addresses". If your code is listening bound to the 127.0.0.1 loopback IP address, it won't accept remote connections by definition.

The goal here is to set up a hostednetwork wifi on a server (fake server, it's Windows 10 x64), the client connect to this wifi, then connect to the website on the server. This is done by creating the hostednetwork :
netsh wlan set hostednetwork mode=allow ssid=BORNE-1234 key=12345678
netsh wlan start hostednetwork
IIS is configured with a simple website in it. And I just tried every bindings possible :
http borne.fr 80 *
http borne.fr 80 192.168.137.1
http (Empty) 80 192.168.137.1
http www.borne.fr 80 *
http www.borne.fr 80 192.168.137.1
Then i edit the C:\Windows\System32\drivers\etc\hosts file to add this line :
192.168.137.1 borne.fr www.borne.fr
I even tried with 127.0.0.1 but nothing works. On a browser on the server, borne.fr works. But if I connect to the created wifi with another machine borne.fr give the error ERR_NAME_NOT_RESOLVED whereas with the IP address it works. I tried everything mentioned here https://serverfault.com/a/452269.
I also added an exception on the firewall (in and out) for port 80.
Any Ideas ?
You need to also set "192.168.137.1 borne.fr www.borne.fr" on another machine.
If "192.168.137.1 borne.fr www.borne.fr" is not set on another computer, it will not know what the IP address of www.borne.fr is.
Hosts files were used to resolve hosts names before DNS. hosts files would be massive documents used to aide the network name resolution.
If you have a DNS server in your LAN, you can configure the DNS server to resolve www.borne.fr to 192.168.137.1.
I have a NodeJs/Express project in Alibaba cloud based Ubuntu server.
When I run project and access with curl localhost:3000 and curl 127.0.0.1:3000 it works!
When I access with IP public, e.g. curl 192.x.x.x:3000 it doesn't work, even though I have edited config in Express project in some code to : server.listen(3000,"0.0.0.0") OR server.listen("3000","192.x.x.x").
FYI I have Apache on this server. When I access on Internet with IP public no problem.
What can I do to solve this problem? Thanks beforehand.
PS: the 192.x.x.x is my IP public and it works access with Apache project
Issue the following command to open port 3000 for TCP traffic.
sudo ufw allow 3000/tcp
You have to configure your security ground and create a inbound rule to allow port 3000. Follow this guideline.
https://www.alibabacloud.com/help/doc-detail/25471.htm
Make sure you allow TCP traffic or all traffic from all sources to the port 3000 as the inbound rule.
The fact that you can access your service locally - but not publicly could mean 2 possible configurations:
The server running your application has blocked the port 3000
You have not configured your server to map the port 80 of a specific route to the port 3000
It is highly possible that a most essential part of your server configuration has not been done.
I've trying to run my nodejs/expressjs application on my godaddy server, but any port I use times out. I've tried using the application on my local device and it works fine. I have a snippet of my connection below.
var app = express();
app.listen(8080, function() {
console.log("Listening on port " + 8080);
});
When I run the program through ssh, I get no errors
node index.js
Listening on port 8080
But when I go to the corresponding location in my browser, I get:
xxx took too long to respond.
ERR_CONNECTION_TIMED_OUT
I'm pretty sure it has to do with running on the godaddy server. If anyone has experience using this service with nodejs, is there a specific port I should be using, or is there any other setup I should do?
Do you have a VPS with GoDaddy right? So I assume you have also root access.
SSH into your GoDaddy server as root and check if the node.js app actually listens on that port:
netstat -tunlp | grep 8080
If you see any result there for the node.js app and that port then the port is open.
By default, there should be a firewall on your server which might block most of the ports and allows only the necessary incoming traffic.
You can check if there is any rule for that port by issuing the command bellow:
iptables -nvL | grep 8080
If any result is returned, then you have to add an iptables rule to allow access to that port. There are multiple methods to do that:
permit full access from your IP access to the server
permit your ip to access port 8080 on the godaddy server
permit outside world to access port 8080 on your server
You could read any iptables guy, it's pretty easy to add/edit/delete firewall rules. Most of the cPanel/WHM servers come with CSF Firewall (which is based on iptables and perl scripts).
In order to allow an ip address to your firewall (if you have CSF Firewall installed) you have to issue the following command:
csf -a ip-address
I hope that helps!
I have website working fine on my local machine as host name hml.frontend in the hosts file: 127.0.0.1 hml.frontend
In IIS I have bindings as hml.frontend 127.0.0.1 and hml.frontend 192.168.1.94. The latter I used ipconfig to get my local ip address issued to me by my BT Home Hub 5 router.
In windows 10 firewall I have allowed App/Feature NetLogon service and World Wide Web services (HTTP).
In advanced settings in Inbound Rules I have added a rule which allow the connection from all sources to ports 80 and 443. Scope is any IP addresses.
On my macbook I have added the 192.168.1.94 as hml.frontend to the hosts file.
I can ping hml.frontend OK from the macbook.
However from a web browser the http://hml.frontend site cannot be reached from the macbook.
telnet 192.168.1.94 80 from the macbook says unable to connect to remote host.
Back on the PC I have done netstat -na to see which ports IIS is listening on and 127.0.0.1:80 is there and so is 192.168.1.94:139 and many more ports against that IP address but not port 80.
Any ideas what I can check to get my PC to listen for that website hostname on port 80?
I got it to work, I was on the right track that the IP address was not being listened to.
In order to add the ip address I have to be listened to, I went into cmd as adminstrator, did
netsh
http
show iplisten
'show' result shows that just 127.0.0.1 was being listened on port 80
add iplisten ipaddress=192.168.1.94
show iplisten
quit
'show' result shows that now additionally 192.168.1.94 is being listened on port 80
Then I went back in with
netstat -na
And now I see the line I want:
TCP 192.168.1.94:80 0.0.0.0:0 LISTENING
Some information was gained from this article.

The site is now reachable from my macbook using the hostname http://hml.frontend
I have a VPS with node.js installed, I already uploaded a basic example to test it on the server, so I tried doing this:
I access by SSH, navigate to my project folder and run
node app.js
I get this message
Express server listening on port 8080
I thought i could see my app here
example.com:8080 or server.example:8080... but nothing. Then I tried with the info from os.networkInterfaces(); and os.host(); and still nothing happen
could you help me out? as you can see I am a total noob on node.js. What I'm doing wrong? or what should I do before running my app? Something related to DNS's? i have no idea
How do you ssh to your host? with ip or name? Is it something like:
ssh root#example.com
if so then at least you know your DNS is ok.
Once on the server do a
netstat -a
if you find *:8080 then your server is listening in the default ip. If you see something like 12.23.45.67:8080 then this number is the ip your server is listening.
ifconfig
will give you the servers ip. This should be the same as the ip of example.com. If not then maybe there is some router/firewall in front of your server and you have to configure that to allow port 8080 to reach your server.
if someone ever has the same problem this is how i solved on CentOS:
Open this file
/ Etc / csf / csf.conf
Add the required port
Allow incoming TCP ports
TCP_IN = "20,21,22,25,53,80,110,143,443,465,587,993,995,26"
Allow outgoing TCP ports
TCP_OUT = "20,21,22,25,37,43,53,80,110,113,443,587,873"
Restart
# # Csf-r
