upgrade, webmin, virtualmin, error, virtual-server::list_system_info failed : Undefined subroutine &net::active_interfaces

Submitted by JLR-GPF on Tue, 08/11/2015 - 13:39

Hello Everybody,

I have a CentOS 6.6 with virtualmin installed for more tan 2 years. Even doh I'm very new to virtualmin.

Yesterday after running the update like every month I get the following error: 'virtual-server::list_system_info failed : Undefined subroutine &net::active_interfaces called at /usr/libexec/webmin/virtual-server/virtual-server-lib-funcs.pl line 3617. '

I found a similar issue here: https://www.virtualmin.com/node/37685

But that only applies to 'Authentic Theme 14.01'. Since I don't use that, it must be a different problem.

Could you point me some hint where to look?

Status: 
Closed (fixed)

Howdy -- you may want to try the process described here in case this helps:

https://virtualmin.com/node/21975

Also, be sure that you're using the most recent Webmin, Virtualmin and Virtualmin theme version available. If you continue to have problems, let us know what the versions are of those 3 things.

Hi andreychek,

Thanks for your post, sorry for the delay, I inadvertently uncheck notifications so I missed your post.

Back to you suggestions, I review the indicated post.

In my case the Centos is not on Amazon, but on Azure. I restarted the 'webmin' process and checked that there is only one running, but the error continues.

How could I find what version of each one I'm running? I run the following: yum list installed | grep @virtual

Results on attached file.

Is this enough to find which version of each?

Thanks,

Could you run these commands -- this will show the versions of the main software that's running:

rpm -qa | grep webmin
rpm -qa | grep wbm-virtual-server
rpm -qa | grep virtual-server-theme

Also, if possible, could you attach your /etc/webmin/miniserv.conf file? Thanks!

Submitted by JLR-GPF on Thu, 08/20/2015 - 14:01

Versions are:

rpm -qa | grep webmin 
webmin-1.760-1.noarch

rpm -qa | grep wbm-virtual-server  
wbm-virtual-server-4.18.gpl-1.noarch

rpm -qa | grep virtual-server-theme  
wbt-virtual-server-theme-9.0-2.noarch  
ust-virtual-server-theme-6.9-1.noarch 

The '/etc/webmin/miniserv.conf ' is here:

Thanks you.

Can you also try going to Webmin -> Networking -> Network Configuration -> Network Interfaces, and see if you get the same error there?

Submitted by JLR-GPF on Thu, 08/20/2015 - 15:08

Hi JamieCameron,

I'm afraid I don't have that option. Anyway the interface is basically useless since in every menu, the information frame is broken and the displays the error.

Attached to screenshot..

Thanks

Can you post the /etc/webmin/config file from your system? The issue maybe that your OS is detected incorrectly, which I can tell from that file.

This is my /etc/webmin/config (some data striped for security reasosn):

Ok, there's the problem - your system is identified as "Generic Linux"

If you go to Webmin -> Webmin Configuration -> Operating System and Environment, you should see an option to switch the OS known to Webmin to the currently detected one.

Hi JamieCameron,

Operating system according to Webmin: Generic Linux 2.6
Changed to: CentOS Linux 6.6

Internal OS code used by Webmin: Generic Linux 2.6
Changed to: redhat-release 6.6

Detected operating system Generic Linux 2.6
Update Webmin to use detected OS (checked)

After reboot somethings begun to work but only the "webmin" part, the Virtualmin part of the screen is gone.

I also review "Webmin -> Webmin Configuration -> Operating System and Environment", and the thing are the same as above; the detected OS still is "Generic Linux 2.6"

Any ideas on how to revive the Virtualmin? How I make Webmin to properly detect the OS?

Thanks

Can you post the contents of the /etc/redhat-release file from your system?

Submitted by JLR-GPF on Thu, 08/27/2015 - 08:03

JamieCameron,

By your suggestion, I found that the problem was with /etc/centos-release.

Originally the file contents was:

CentOS release 6.6 (Final)

For a reason not related (some auditing software and the role assigned to this VM), I changed 6 month ago to:

CentOS Server release 6.6 (Final)

Since 'redhat-release' is a link to 'centos-release', this change apparently "confused" virtualmin when pressed the "AutoDetect OS".

I managed to fix the Virtualmin AutoDetect , and my auditing software with the proper role assigned change the '/etc/centos-release' with the following string:

CentOS release 6.6 (Final) Server

Thank you very much for your help! JLR

Ok, that would explain it.
