Virtualmin admin login not accessible

Hi,

I’ve virtualmin installed on Ubuntu 14.04. It has eight virtual servers configured since last six months. Everything was working fine till this morning when the virtualmin admin login is no more accessible through browser. It return “Can’t open this page because the server is not responding”. I’ve also tried the IP instead of domain name i.e. https://IP:10000 but still return the same error.

All of the websites are running fine. However, the pop server has also stopped so associated emails can’t be downloaded through gmail client or outlook.

Please help!

It could be that server crashed during the night and some of the services didnt come back, or you hit memory/cpu limit, or it was (D)DoS attack… and so on. If you can log with SSH you could check if Wmin is up and running if not try to manually start. If you cant start Wmin then next step would be to check log files. For sure something happened because services dont go down without reason.

Thans for reply.

I have logged in through SSH and reboot the server. Still the same issue.

The memory status is given below;

Every 5.0s: free -m Mon Jun 1 11:16:18 2015

total used free shared buffers cached

Mem: 2001 1817 184 375 7 722

-/+ buffers/cache: 1087 914

Swap: 4095 5 4090

I’ve also restarted the webmin by running: /etc/init.d/webmin restart. All servers starts fine!

The individual error logs of the websites shows no error. Where can I find error log for the virtualmin itself?

Thanks
Adil

Here are some of entries from one of the VS error.log file;

Could you please see any problem in here? I can see some weird links in errors related to mod_fcgid. What do they mean?

Thanks,

Log files should be where Ubuntu usually store all other log files, not sure as i never used Ubuntu but on Centos that is /var/.
If you start Wmin you could just login and check the log files from the control panel. If Wmin cant start then you could try to restart entire server and see if all services will boot up with the server. If the problem is still present then i would suggest to wait for Wmin guys. Either way for what i can see the memory is not the problem.

Howdy,

It’s just Webmin/Virtualmin that isn’t accessible, is that correct? The websites themselves are working fine?

If so, you may want to take a look at the Webmin logs, which you can see in /var/log/miniserv.error.

Also, you can verify that Webmin is running on the standard port with this command:

netstat -an | grep :10000

Lastly, you may want to make sure there isn’t a firewall blocking that port. You can see all your firewall rules with the command “iptables -L -n”.
