Okay, webmin is running. But port 10000 is closed for public traffic.
-
Check if webmin is configure to run on a different port than 10000
-
Check if your firewall is blocking port 10000
-
Check if your VPS provider has a firewall
Try restarting webmin with following command,
service webmin restart
i suspect firewall is blocking port 10000
can you please help me to find out
From VPS side all ports are opened
Try,
ufw status verbose
dhiraj@webt1:~$ ufw status verbose

Try stopping firewalld temporarily. And see if you can access Webmin. Port 10000 is repeated here.
stopped firewalld temporarily, but no luck
even i am not able to tlenet 10000 port from outside
i can telnet on 10000 port locally
Run ‘sudo netstat -ntlp’ and see if it’s listening at all. (If it says no such command found you need to intall the net tools with ‘sudo apt install net-tools’)
sudo netstat -ntlp

Are you hosted someplace with a firewall?
Are you hosting yourself or somewhere else?
You’re setup is using IPv6 and some providers don’t support it.
Notice your port 20000 is on regular TCP? It works.
So that’s the issue - I’m betting your provider doesn’t support IPv6 and that’s why it’s not working.
try this to check open ports
His port is open. It clearly shows that in his report he ran right before you posted. It’s even highlighted.
But his port 10000 that doesn’t work is on IPv6 while his 20000 port that works is on regular TCP. That’s the problem.
i see
tcp 0 0 0.0.0.0:10000 0.0.0.0:* LISTEN 6302/perl
is that not webmin listing on ipv4 ?
As usual, you miss the point.
He doesn’t have port 20000 listed on IPv6 and it works just fine. He only has that listed on 10000. That’s why 10000 isn’t working - there’s a conflict there for some reason that needs to get sorted.
Again, that’s my entire point. You have port 10000 on IPv4 and IPv6 and it’s not working properly.
On the other hand, you have port 20000 on IPv4 only and it works.
I would disable IPv6 and see if port 10000 starts working. If it does work with IPv6 disabled, then you know that’s the issue.
