[webmin-l] Confusing memory usage shown

[Chris <chr...@gm...>]

This is webmin 1.890 on a Ubuntu 18.04 system. I just upgraded from 4GB
to 16GB of ram yesterday. Top shows for memory installed and usage:

KiB Mem :15354192 total,   567168 free,  3916928 used, 10870096
buff/cache
KiB Swap:  4089852 total,  4089852 free,       0 used. 11417092 avail
Mem

While webmin shows

Real memory 	7.11 GB used, 14.64 GB total

I'm just curious as to why there's such a difference in what Top shows
and what is shown on the webmin system information page.

Hello Joe

Thanks for the explanation. Yes, I realized this as I just ran into the 
same problem on a cloud server also running Ubuntu 18.04.1.LTS.

Re: [webmin-l] IPTABLES issues on Xubuntu 18.04.1 and laptop

[Joe C. <jo...@vi...>]

Ubuntu 18.04 uses a new network configuration system called netplan. 
Webmin does not yet fully support it (Webmin devel version 18.91 has 
some support, but there are still bugs and missing bits).

You'll either need to switch to the previous network configuration 
scripts, or wait for support in Webmin to be finished.

[webmin-l] IPTABLES issues on Xubuntu 18.04.1 and laptop

[Joaquim H. <jo...@we...>]

Configuring a reasonably new laptop (2017+) with Xubuntu 18.04.1.LTS, I 
ran into a snag when running Webmin and trying to go to Networking -> 
Linux Firewall:


Rules file /etc/iptables.up.rules
  HTTP/1.0 500 Perl execution failed Server: MiniServ/1.890 Date: Wed, 
22 Aug 2018 22:08:29 GMT Content-type: text/html; Charset=iso-8859-1 
Connection: close
Error - Perl execution failed

Undefined subroutine &net::get_interface_defs called at 
debian-linux-lib.pl line 63.


Not quite sure why as I've installed Webmin on previous laptops too 
(albeit not with any *Ubuntu 18.04 OS). The network interfaces are:

enp0s31f6
lo
wlp59s0

The wl559s0 is the currently active interface (WLAN) and has a valid IP 
address. enp0s31f6 is the LAN interface, but no cable is attached and no 
address has been assigned.


Webmin installed just fine and behaves well in other modules.

Hi,

Recently on one of my system miniserv.error log reported
too many children (99 > 50)
The above message started from 51 and continued till 99 and after that
system restarted because of too much memory usage by perl.exe process.

Why webmin didn't stop creating child processes after 51?
There are 99 children totally when system restarted.

[webmin-l] Clamwin Version Problem

[MAR <we...@ro...>]

I recently installed/updated to the most recent version of Clamwin on my server, and I am now receiving this error when going to the module to use it:

WARNING: Your version of ClamAV is not compatible with this module. Please check that you have installed a recent enough version of ClamAV.

I confirmed that it is the most recent version, as shown here:

Is there a way to correct this?

Check your Apache config for a <virtualhost> block for this domain, and
make sure it exists with the correct IP and ServerName line.

I think I've tried this in the past. It's as if something gets "tangled" 
due to the number of monitors or something.

Perhaps I should try to set it up on another server with identical 
monitor patterns and see if I then get exact duplicate reports, I should 
- if the server actually is down.

If the server isn't down, I'm not sure why Webmin can't ping it.

Re: [webmin-l] Forcing PHP-FPM upon restore

[Joaquim H. <jo...@we...>]

The old system uses php-cgi/fcgid.

The new system uses php-fpm.

The "problem" with the new system is that it also supports php-cgi, or 
som Webmin thinks. This is probably due to me accidentally restoring 
Virtualmin settings as well (I've gotten confused about that in the past 
too).

But I wanted Webmin/Virtualmin to "override" this and force the use of 
php-fpm upon import to the new system.

Sorry if I was unclear.

One possible work-around is to edit the ping monitor and increase the number
of failures before emailing from the default of 1 to 2 or 3.

You could do this manually already by copying files from /etc/webmin/status
to the new system.

On restore Virtualmin will use the default PHP execution mode, but only
if the original mode from the backed-up domain isn't supported on your 
system. Is that the case here?

[webmin-l] "Ping monitoring" with Webmin fails repeatedly, but is often false positive?

[Joaquim H. <jo...@we...>]

We use Webmin for basic monitoring of a number of servers. We usually 
set the check interval to somewhere between 15 and 30 minutes, depending 
on which server it is.

Quite often, we'll get a "monitor down" for a server, at which point we 
check the server and find it to be very much up and running. On the next 
check, Webmin will again report the server (or monitor) to be up. We 
typically see this reported from "monitoring servers" that have a lot of 
checks defined. Could this somehow confuse Webmin or congest the network 
stack somehow?

If this only happened once or on one server, I wouldn't worry so much 
about it. But we recently switched one of our "bigger" monitoring 
servers from one cloud platform to another, which completely different 
architecture behind it, and then re-created the monitors on the new 
server. Sure enough, pretty soon we began seeing false positives again.

(By the way, it'd be nice if one could export monitors and then 
re-import them on another server)

Since their configuration is not interchangeable, there can't be a way to do

[webmin-l] virtualmin - validation fails

hi,

I have one installation where one subdomain (and only one) strangely fails
the nightly validation:

==
Virtual server validation
-------------------------
sub.domain.com
    Apache website : No Apache virtual host for sub.domain.com found
    SSL website : No SSL Apache virtual host for sub.domain.com found
    Log file rotation : No webserver log found for virtual host
sub.domain.com

the domain works just fine. where should I start looking?

[webmin-l] Forcing PHP-FPM upon restore

[Joaquim H. <jo...@we...>]

Is there a way to force the use of PHP-FPM (over other variants) when 
restoring a backup of a Virtualmin site?

For some reason, I managed to also import Virtualmin settings from 
another server while restoring a backup, and I can't seem to get rid of 
the other PHP versions in Virtualmin/Webmin.

There is only PHP-FPM installed, but I wants to offer mod_php, fcgid, 
and php-fpm. I've set the default mode to PHP-FPM.

[Jamie C. <jca...@we...>]

What default PHP execution mode do you have selected for new domains? This is set at System Settings -> Server Templates -> Default Settings -> Apache website.  

On 28/Jun/2018 13:52 Joaquim Homrighausen <jo...@we...> wrote ..    After enabling mod_cgi, I could proceed with saving enabled features.  Creating a new website generates this:  "Performing other Apache configuration .. .. configuration failed : PHP configuration mode fpm was selected, but is not supported on this system!"  Doing a virtualmin config check reveals the same, and it complains about mod_fcgid. Enabling it doesn't help either.  Not sure why this is needed as proxy/proxy_fcgi seems to do the job if I configure Apache+PHP-FPM by hand.  Sorry for the rant, but I really am/was expecting this to have been resolved by now :) mod_php, php cgi, and all these other methods of running PHP seems to be a bit "out of date" if you ask me.  And turning to nginx instead of Apache isn't an option either since that doesn't really work well with Webmin/Virtualmin.     -joho
