I am using Nodejs with the express, bcrypt and body-parser packages on an ubuntu linux system.
Everything works fine so far.
However, I´ve been wondering if there is an easier way to connect to my website.
Until now, I have to type in my IP adress, e.g. https://XXX.XXX.XXX:3000 to actually see the content.
I´ve already tried avahi-daemon but did not get it work. Whenver I try 'hostname.local' I get the same error: Firefox is unable to connect to server.
However, using the IP-Adress: https://XXX.XXX.XXX:3000 works.
I would like to access my NodeJS sever with something similar to: computername.local
FYI: I just want to use it in my local network at home.
Does anybody have any idea how to get this work?
You have a couple choices. The easiest,if available, is probably to setup your home router to always assign it the same IP address (how to do that will vary based on your router). If your router has it available, you could also set a host name for it there in DNS settings.
If your router doesn't have DNS settings available, then you can add a line to each of your home computers /etc/hosts file (if memory serves Windows has it in C:\etc\hosts). Let's say the IP you give the server is 172.16.1.11, your hosts entry would be
172.16.1.11 computername.local
You could also setup your own DNS server in your house, possibly even on the same machine as has your node app, and then configure it to handle the one address before forwarding DNS requests for others to your ISP but that seems like overkill if you have just one app.

I have a local Raspbian installation running Nextcloud. I forwarded the ports on my AVM FRITZ!Box 7530 router (running the latest version, FRITZ!OS: 07.29), so the website is reachable if I enter https://<public IP>/ from both inside and outside of the network.
I then registered with https://freedns.afraid.org/ to obtain the subdomain mysubdomain.jumpingcrab.com, which I want to get a Let's Encrypt certificate for. But in trying to do so, I realized that https://mysubdomain.jumpingcrab.com is only reachable from outside of my local network.
After researching, it turns out that my router needs an exception for its DNS rebind protection, so according to the manufacturer's instruction, I enter mysubdomain.jumpingcrab.com there and restarted my router. From what I could find, this should solve the problem and did so for many others, but I can still only reach the website either internally via IP or externally (with both IP and URL). The error I am otherwise greeted with is "The connection has timed out".
I'm using node js trying to send my web-page to my network, I successfully call localhost:port in my computer using express as server, the webpage loads fine trigger my webcam which I used to streaming in the webpage, and then im working to make a simple app in my phone to directly access my server, so my questions:
1.How do I able to access my server from different devices in the same wireless-network? by calling ip + port ?192.168.1.104:9001 ? cause i've tried and it didnt work.
2.I've found https with .pem something like that, is that the answer ? is there also any other way ?
3.maybe any advice before i work to make my web-app to devices? using koa? i don't even really know what is that, but i'm happily take any advices.
EDIT: i've read How could others, on a local network, access my NodeJS app while it's running on my machine?
let's say I simply using random router, so i can't configure my router-port, my server in my pc and my phone join in the same network, trying to access the server in my phone
1.How do I able to access my server from different devices in the same wireless-network?
All you need to do is find your server's IP address in this same wireless-network, and find the Node.js application's port. Then access the following URL in other devices:
http://{server_IP}:{port}
However, there are some points need to check:
Need to check firewall and confirm the port is not blocked, server IP is not blocked by test device, and test device IP is not blocked by server.
Need to check whether there is any Proxy setting in server and test device. If there is any, disable the proxy.
A computer may have many IP addresses at the same time, you need to find the correct one in the same wireless-network. For example, If you install a virtual machine software such as VMware and run a virtual system inside, your real computer will get IP address as 192.168.*.* -- this IP address looks like an intranet IP in wireless-network, but it is not, and can never be accessed by test device.
2.I've found https with .pem something like that, is that the answer?
No, HTTPS has nothing to do with this problem. HTTPS just add security (based on HTTP layer), it does not impact any HTTP connectivity. Actually, to minify the problem, it is better to only use HTTP in your scenario.
There is only one very special case that may bring your problem by HTTPS -- the test machine is configured and will block any non-HTTPS connection for security.
3.maybe any advice before i work to make my web-app to devices? using koa?
My suggestion is: As there is an HTTP connectivity issue, the first step is trying to find the root cause of that issue. Thus, it is better to make a simplest HTTP server using native Node.js, no Koa, no Express. In this way, the complexity of server will be reduced, which makes root cause investigation easier.
After the HTTP connectivity issue is fixed, you can pick up Koa or Express or any other mature Node.js web framework to help the web-app work.
4.let's say I simply using random router, so i can't...
Do you mean your server get dynamic IP address by DHCP? As long as the IP is not blocked by test device, it does not matter.
Suppose if my ip address is : 192.65.35.12. In this machine I'm running node server. I can access the webpages by using this url: http://localhost:3000/ in the same machine.
But, if I'm trying to access the node server from a remote machine having the ip 192.65.35.11. It does not work. I used the below url to access the url from the remote machine: http://192.65.35.12:3000/
I'm facing network connectivity issues.
Do, I need to change any settings in node.js for remote access.
Then, how can I access the node server from the remote machine.
if you can access localhost:3000, then type in 192.65.35.12:3000 on same machine. and if you are having problems connecting, then no outside computer going to connect. and you need to adjust your nodejs settings.
if you have server at home, and trying to connect from some place else not at home. you are more likely looking for something like "dynamic ip address" example: http://www.noip.com/ it helps getting past ISP (internet server providers) and your own routers, and publishing your ip address.
if you are dealing with 2 computers in your same house or business and passing through your own router, try changing the 192.65.35.12 to DMZ. basically by passing all router safety, if that happens, you are not opening correct ports on the router. or not setting other setting correctly.
I wanted to test my ReactJS + NodeJS website on another machine on my LAN, so I changed the server host ip from localhost to 0.0.0.0 as described in this answer. I noticed that although I could access the server from a remote machine, all I could see was the title and favicon (the rest was a blank page). I tried another approach of using the ngrok module as described here (which happens to be the answer to the same question as the previous link). I still got the same blank page.
The GET requests to the server are shown below (as shown by ngrok).
/landing is a page I was trying to access. Can someone explain whats happening?
PS: The server is running on a Mac and I'm trying to access the page on an Ubuntu machine. Also, I'm using this react-redux boilerplate. Webpack is also being used along with hot reloading.
Did you try changing port settings in firewall?
Go to firewall settings and allow the respective port for inbound
I've been developing locally on a little ubuntu netbook with xampp for about 7 months. Two weeks ago I got a computer I'd like to use as a server. I've installed the latest Ubuntu distribution and xampp, moved all my files over, and forwarded port 80. I've also got a domain name from dyndns.com which is being updated by a client which runs in my router (a Netgear WGR6154 v8).
Now, when I try to access my server by typing in the address I got from dyndns.com the browser loads until it timesout. I can access everything locally using localhost as the address so I believe xampp is running, just unable to connect with the internet.
In order to be able to view my files over the internet what should I do next?
Thanks to all in advance...

You have a combination of issues here, and that is something of a problem. Each issue is complex in an of itself. Here is what I would recommend to get you going for certain.
First verify that you can surf the web from your server. This will confirm that you have a working ethernet interface.
Step 1 make sure that XAMPP, and your files are viewable from your home network. I assume you are using something like 192.168.1.X for your network and perhaps your server is 192.168.1.10
Go to another computer in your house and type http://192.168.1.10/ and see if you can see your files. If you can then you know that the server is properly configured and XAMPP is working.
Then add an entry to your hosts file to resolve yourdnsrecord.com (or whatever your dyndns record is) to your private ip address. Then when you type yourdnsrecord.com into a browser from that computer you should still get your files. This will rule out your server being improperly configured to listen for that domain name.
Next you need to test to see if there is a firewall problem. To simplify this, first remove your home router from the equation. Instead, place your new server directly onto your internet connection. (assuming you can). This way, you do not need to have NAT or firewalls properly configured. Your dyndns name should map to a public IP and your server should then have that IP and be connected directly to the Internet. If you have your server directly connected, and the command ifconfig from the root prompt returns the same public IP address that your dynamic dns record is point to, then it should work.
It will make your life easier if you have an iphone or some other way to test how your network is seen from the Internet.
If your public IP as shown by ifconfig is different than the IP record in your dyndns account, then your dynamic dns update script is broken. manually set the IP, and see if things work.
It is very possible that this will not work. Some ISPs firewall port 80 preventing their subscribers from hosting servers. Once you have your server directly connected to the internet you can test this (even if your dns is not working) by using the public IP address. As root, type ifconfig from the command prompt to get your public ip address. Then type the command tcpdump -i eth? port 80 from the root prompt. eth? needs to be the same interface that you saw had a public IP address from the ifconfig command. usually this is eth0 but it might be wire0 or something like that.
This command will show you all traffic coming on port 80 to your server.
From an iphone (or whatever second Internet connection you have) browse to the IP address that you got from your ifconfig command. If you see something on your server (and it is directly connected to your ISP) then your ISP is not firewalling you.
If you can get to your server, when it is directly connected to the Internet, either by IP address or by DynDNS address, then your ISP is OK and it is time to debug your firewall.
Two things need to work for your firewall to be configured NAT, where the public address that your router gets from your ISP is converted into your private network and a firewall rule which permits that traffic. If you get this far, then you know your firewall is the problem and then it is just a matter of getting its configuration correct. There are far to many home routers to document here, but you usually can find how-to instructions for your router for this task from the manufacturers website (usually it is part of the manual)
If you follow these instructions exactly you will get your system working. Make comments on the process and I will be happy to modify this to make it clearer.
HTH,

You should make sure your xampp is not listening to only the localhost.
to do so edit your apache configuration file and check and search for Listen directive
you should be able to know also by analysing the output of netstat -a.
After that make sure your router is forwarding properly, using tcpdump would help.
drop me a comment if you need more help.
