How to change Webmin port using terminal

Change the Default Port and Add the Listener Port

Option 1 Using Terminal

Google cloud, azure, and amazon block access to port 10000 by default, as all have a firewall activated. This may prevent you from logging into http://localhost:10000/ from another system on your network or over the Internet.

Edit the miniserv.conf:

/etc/webmin/miniserv.conf

and change the default port number (10000) to any port you like, for example 81, or 443.

sudo nano -w /etc/webmin/miniserv.conf

Find the following line 1 and change:

port=10000
addtype_cgi=internal/cgi
realm=Webmin Server
logfile=/var/webmin/miniserv.log
errorlog=/var/webmin/miniserv.error
pidfile=/var/webmin/miniserv.pid
logtime=168
ssl=1
no_ssl2=1
no_ssl3=1
no_tls1=1
no_tls1_1=1
ssl_honorcipherorder=1
 

How to change port default port to an uncommon port. Port 10000 is heavily targeted by hackers to gain access to Virtualmin server. Of course they can’t get in without the correct password, but sometimes some of them gets through. So it’s best to prepare for the worst.

We need to tell Webmin to stop using TLS/SSL, as Apache will provide that for us going forward.

...
ssl=1
...

Change the 1 to a 0 This will tell Webmin to stop using SSL.

Now, you need to restart Webmin.

sudo systemctl restart webmin

Or

sudo /etc/init.d/webmin restart

Following messages will appear after running that command.

(base) rck@redhat:~$ sudo /etc/init.d/webmin restart
Stopping Webmin server in /usr/share/webmin
Starting Webmin server in /usr/share/webmin

After a fresh restart the Webmin server should be running again.

1. 1. Login to Webmin panel.
   2. Expand Webmin and select Webmin configuration
   3. Click in Port and addresses.
