Unable to access Webmin through browser

Question

I followed DigitalOcean's tutorials on how to set up your server with SSH, creating a new user, firewalls etc. The first tutorial in the series is linked under:

https://www.digitalocean.com/community/tutorials/how-to-connect-to-your-droplet-with-ssh

I've also installed Webmin on my server, but I still can't get a connection to the server by using the web-browser. It just loads for a long time and then says it can't establish a connection. The URL's I've been using are:

"Just-my-IP-adress" and "https://Just-my-IP-adress:10000"

The last one to open the Webmin administrator.

I'm not sure what else needs to be done to get a response from the server. This is all new to me, so you shouldn't assume that anything besides the tutorial I followed above has been done.

Any rookie-mistake-suggestions would be appreciated.

UPDATE1: After following this tutorial to install LAMP, I now get a response when just using my IP-adress, webmin is still not responding, but I assume it was not properly installed since I did not have LAMP installed when I did the Webmin-installation.

UPDATE1: After installing Webmin again, I still can't access it through the browser. I tried the command:

nc -zvw 3 <my-ip> 10000

in the terminal and got this as a response:¨

Connection to 45.55.191.35 10000 port [tcp/webmin] succeeded!

So I guess the port is open and I should be able to connect to it, but it won't let me use the GUI in the browser.

Answer 1

Please try to restart webmin with the following command and check if you are getting any error.

/etc/init.d/webmin restart

If it's working fine, Then defiantly there is an issues with the firewall OR some ports are blocked at your DC end. Please try to stop firewall and check again.

Answer 2

try this ... it's working for me

iptables -I INPUT 1 -p tcp --dport 10000 -j ACCEPT
service iptables save
/etc/init.d/iptables restart

open both link in Browser

https://your-IP:10000 and http://your-IP:10000

Answer 3

Digital ocean sets up your basic firewall with the '1-click' LAMP stack. All ports but ssh and http are blocked. I think the tutorial has you setting that up as well.

Run sudo ufw status to see what ports are currently allowed

and then sudo ufw allow 10000/tcp to allow access to the one webmin needs.

Answer 4

It will solve your problem

1. nano /etc/webmin/miniserv.conf
2. now change ssl=0 into ssl=1.
3. Press Ctrl+o and Enter to save it.
4. Press Ctrl+x to exit the nano.
5. Now restart webmin service webmin restart

Cheers.

Answer 5

Try:

sudo iptables -A INPUT -p tcp -d 0/0 -s 0/0 --dport 10000 -j ACCEPT

Answer 6

Port 10000 is listening so, so you either have a Webmin installation problem, or the SSH may be creating a problem for Webmin.

I would recommend disabling the SSH, going back to non-SSL. Check and see if port 10000 is Webmin GUI? If not, purge Webmin install.

apt-get --purge remove webmin

Reinstall Webmin using the instructions from Webmin

http://www.webmin.com/deb.html

With SSH still disabled check

http://Just-my-IP-adress:10000

I would suggest using Webmin to install SSH.

In general it's a better process to build and verify your VPS in stages, testing each component before adding on another. No matter what Digital Ocean may suggest, integrating all the components together at once and flipping the switch leads to difficult to track down issues that often require you to start over and rebuild anyway.
