Malkavian's questions

I installed opensearch and opensearch-dashboard in my ubuntu vm. When I try to find out the resources used by opensearch-dashboard with the command

top -U opensearch

i just get

and I think that that kind of infomation aggregate opensearch AND the opensearch-dashboard how can I find out only the memory cpu and disk space used by the dashboard?

After issuing do-release-upgrade the Notebook HP Pavilion - 17-g050nl (ENERGY STAR) shows the verbose boot but does not show the login screen. The only way I have to get into the system is to: power down, power up, hit esc to get to the hp boot menu, hit enter to continue, hit esc to enter into the grub boot menu, select ubuntu recovery mode, open a root shell, edit the grub default and remove quiet spash or whatsoever and replace it with nomodeset, save , perform update grub, reboot. I guess Ubuntu 20.04.1 LTS does not recognize the video card or video driver that should be used with this hardware. What Drivers should I use to stop using nomodeset? How can I fix it? the output of sudo lshw -C display

I inherited an ubuntu 8.10 server that is currently running as a samba server and apache web server. I would like to make a new server with ubuntu 19.10 and copy the existing configurations on that one. I usually start from scratch and I never configured samba to integrate with active directory. Will this config in smb.conf be enough?

# Global parameters

        workgroup = domain
        realm = domain.com
        server string = %h NEWSAMBASERVER (Samba %v)
        security = ADS
        password server = domaincontroller.domain.com
        #security = DOMAIN
        passwd program = /usr/bin/passwd %u
        passwd chat = *Enter\snew\sUNIX\spassword:* %n\n *Retype\snew\sUNIX\spassword:* %n\n .

I would like to change the netmask of an ubuntu 19.04 using netplan. I edited the only yaml file that I had, that is \etc\netplan\50-cloud-init.yaml

network:
    ethernets:
        ens160:
            addresses: [10.100.0.78/24]
            gateway4: 10.100.0.253
            dhcp4: no
            nameservers:
                addresses: [10.100.0.8,10.100.0.9]
            optional: true

but if i give the command ip a

I would like the netmask to be 255.255.0.0 . where is the netmask setting?

I have inherited the management of an old server. It seems that there is an intranet site configured to the port 80. In that server it seems that there is also installed vtiger version 5.4italian I would like to publish vtiger site to the port 90 an try it out. the beginning page should be: /var/www/vtigercrm504ita/index.php Can you point me to a guide that tells me what files do i need to edit? this page https://httpd.apache.org/docs/2.4/vhosts/examples.html is not telling what files do I need to edit. i tried:

     nano /etc/apache2/sites-available/vtiger.conf

    Listen 90

<VirtualHost *:90>

        ServerName localhost

        <Directory /var/www/vtigercrm504ita>
                AllowOverride None
                Require all granted
        </Directory>

        DocumentRoot /var/www/vtigercrm504ita

        ErrorLog ${APACHE_LOG_DIR}/vtiger.error.log
        CustomLog ${APACHE_LOG_DIR}/vtiger.access.log combined

</VirtualHost>

but if I go to ip:90 i get ERR_CONNECTION_REFUSED instead of the page /var/www/vtigercrm504ita/index.php

I have an internet site with restricted access, it requires a user and a password. If I use:

lynx -source http://reserved.sindata.it/sinerj/servlet/it.sindata.pgsearch.Sqsearch?action=Showtab&name=arcli > filename

I download a login page. I would like to download content providing username and password, can it be done in linx?

I have an hp pavilion notebook with ubuntu 17.10, when I was using windows, I could run dead island. Under linux on the same machine the game crashes at the first wait screen. If for example I run the game with launch options -nologos -safemode I get the Palm screen, the black screen with wait message and then the game just crash. I also noticed that the game does not make any configuration file since the folder settings: /DI/out/Settings/ doesn't exist. I double checked the integrity of game files. I can provide also the crash.log file (very long log file) since I can't figue out the issue by myself.

To fix a glx issue I had in dota 2 I had to sudo apt-get install libtxc-dxtn-s2tc0 dota 2 works fine, dead island isn't.

I have the following funny experiment. I used a live usb to install ubuntu server 12.04 i386 and webmin on a usb plugged to an intel ss4200-e, i would like to make a headless samba server out of it. webmin shows the following situation on the partitions menu:

the raid menu shows:

and then the \dev\md0 tab shows

how do I mount that /dev/md0 into /mnt/raidarray at boot for example?

On a lubuntu 16.04 xenial machine I'd like to install quake2, more for test than anything. And then I'd like to install a quake 2 server, but first things first: I've copied from my windows partition to my lubuntu desktop the old quake 2 game folder, from a windows install. So on the desktop I have a Quake2 folder, and inside there are: baseq2, rogue, xatrix subfolders. I've installed quake2 binaries with apt: apt-get install quake2

What I'm trying to do is figure out how to have game-package-manager make the relative deb files for the full quake2 (baseq2), the reckoning (rogue), ground zero (xatrix).

Has anyone done it successfully, or does anyone knows the syntax for that?

Can you help me identify the problem?

I managed to install ubuntu and dual boot it on a hp pavillion notebook. To do that I had to press esc and f10 immediately after pressing power, in order to access the bios. Enable legacy in the boot options of the bios. Then I installed and configured linux (debian ubuntu and arch linux) fine. As long as I keep the enable legacy option i get grub after boot. What i would like to achieve is that if i disable legacy support at the bios, the notebook prompts me to grub2. Right now if i disable legacy, the notebook boots windows 10 and ignores grub2. I think it has to do with efi but my limited knowledge stops there.

I'm using ubuntu, lubuntu , kubuntu:

Linux sysop 3.19.0-33-generic #38-Ubuntu SMP Fri Nov 6 18:18:12 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

on a Asus Eee PC Seashell series 1215n that has an Nvidia Ion card. After installing the following packages:

sudo apt-get install nvidia-346 nvidia-settings nvidia-prime

lightdm gdm sddm fails to start. If i want to get a graphical environment i have to: log in in tty, then do:

sudo nvidia-xconfig
startx

could someone help me make desktop manager work?

after installing Lubuntu-Desktop in a regular Ubuntu 15.04 installation i now have Libreoffice-Writer that starts automatically after login. I remember i found the same problem in Ubuntu 14.04 after upgrading from Ubuntu 13.04 but i don't remember how to fix that. What could cause libreoffice-writer to open automatically after login? Could anyone help?
