Need help on Virtualmin website control panel ....

M using Virtualmin / Webmin (with a server) on CentOS 6 32bit.
Suppose my domain name is ‘abcdef.com’ and
my hosting ip address is 111.222.333.444.

Sometime I get “page no found” or “this webpage is not available”, when I try to
access ’ https://abcdef.com:10000/ ’ or ’ https://111.222.333.444:10000/

  • is it a temporary problem or permanent ??

How can I solve it ???

You need to do more tests there. The browser saying “website not available” can have any number of reasons.

Does “abcdef.com” resolve to the correct IP? Can you ping the IP? Is webmin running on port 10000 (netstat -tpln | grep :10000 in a shell)?

Howdy,

Can you try running the command he mentioned above? That will help with the troubleshooting process. The command is the following:

netstat -tpln | grep :10000

That will show whether Webmin/Virtualmin is listening for connections. Thanks!

-Eric

Thanks a lots for the reply Sir…

No, browser saying nothing, no reason code.

Yes, I can ping the IP or my domain name, both and result is fine,
not only that when I use “111.222.333.444”, “abcdef.com” or “www.abcdef.com
it can redirect to my website normally.

If I try ’ https://abcdef.com:20000/ ’ or ’ https://111.222.333.444:20000/
it can redirect me to ‘Usermin’ and mail server too (after a normal SSL certificate warning)

few days ago, m faced the same problem 2/3 times but
don’t know how it solved at that time ??
may be some of my configuration may disturbed something
and reset it later … but once I remember,
I have to re-install OS and Webmin / Virtualmin to restart it access it (ip:10000)

PLEASE HELP to solve it permanently …

Yes Sir, I try it in PuTTY by root and
the result is simple nothing; as follows

:
[root@hostgoutam ~]# netstat -tpln | grep :10000
[root@hostgoutam ~]#

Okay, so it doesn’t look like Webmin is running.

What is the output of these two commands:

free -m cat /proc/user_beancounters

Also, what happens if you start Webmin with this command:

/etc/init.d/webmin start

When I try the 4 commands (one by one)
including ‘netstat -tpln | grep :10000’, the result is as follows

After that I try ‘ip:10000’ again and the good news is - it’s working, now . . . . .
and now I can enter Virtualmin/Webmin as server admin (root) or server owner
and I understand it work for the ‘/etc/init.d/webmin start’ command but
Why m facing this problem, repeatedly ?? and
Do I have to restart Webmin (by ‘/etc/init.d/webmin start’), if I face it again ??

AND THANKS A LOT FOR THE GUIDELINE TO BOTH OF U, SIR …

Hmm, we do see frequent resource problems on OpenVZ-based servers… and in your user_beancounters file, it shows that there were 3 resource limit related failures.

That may mean that you hit some sort of resource limit, and during that time, the Webmin process was killed off in order to free up resources.

You may want to free up some memory, or perhaps ask your provider for some additional guaranteed RAM.

But yes, if that happens again, try starting Webmin again, as that will likely resolve the issue until another resource limit is reached.

-Eric

Eric got it nailed down, as usual it’s a resource issue on an OpenVZ based VPS. :slight_smile:

That system should really get banned for Virtualmin use. :wink: Or maybe, at least the installer script could show a preemptive warning when it detects being run on OpenVZ.

@Eric (andreychek) & @Locutus
Lots of thanks for guidelines and suggestions to both of U
and extremely sorry for the late reply . . . .

M using a VPS of 2.4Ghz CPU, 1Gb RAM, 20Gb HDD and 0.98Gb Traffic Rate.
and with lots of OS installation option as given below.
01-> CentOS 5 (32 or 64 bit)
02-> CentOS 6 (32 or 64 bit)
03-> Debian 6 (32 or 64 bit)
04-> Fedora 18 (32 or 64 bit)
05-> Fedora 19 (32 or 64 bit)
06-> openSUSE Linux 12.2 (32 or 64 bit)
07-> openSUSE Linux 12.3 (32 or 64 bit)
08-> Ubuntu 10.04 (32 or 64 bit)
09-> Ubuntu 12.04 (32 or 64 bit)
10-> Ubuntu 12.10 (32 or 64 bit)
11-> Ubuntu 13.04 (32 or 64 bit)
and I love to use Virtualmin / Webmin with any one of it
(one of the best reason for that is your instant help and guideline)

and m going to install a webscript with it, which need following
a) Apache v.1.3 or LiteSpeed web server,
​b) PHP 5.2.0,
​c) MySQL 4.1.2,
d) Sendmail or Postfix programs for sending emails,
e) can create ​Cron Jobs,
f) RMS (Ray Media Server),
​g) JRE (Java Runtime Environment) ver. 1.6,
h) Ports 1935, 1936 and 5080 should open …
(RMS need red hat base OS so I chose CentOS 6 32bit)

so fur I know Virtualmin / Webmin can support all the
above requirements (form a to h) . . . . . .

A=>>
I just want to know is there anything from above
(from a to h) that Virtualmin / Webmin can’t support ???
(because still now, some of my config not working)
B=>>
As per my VPS config and my requirement, with
Virtualmin / Webmin, which OS U suggest for me ???
