MY SYSTEM
Ubuntu Linux 18.04.1

QUESTION
I need to know what is the best recommended Anti-Virus and Malware protection I can install on my Linux machine.
Please include: Free, Less Expensive, and the Best (no matter what the price), so I can make my decision.

When updating composer (sudo composer update), got the error below:
"- The requested PHP extension ext-memcached * is missing from your system. Install or enable PHP's memcached extension."
Tried very hard to install "PHP extension ext-memcached", but could not get anywhere.
Background: PHP 7.2.10-0ubuntu0.18.04.1 (cli) (built: Sep 13 2018 13:45:02) ( NTS ) on oracle VirtualBox v5.2.22.

Will any gurus shed some light to it?

Hi All,

I am looking to semi-automate the setup of Ubuntu machines.  I don't do that many, so this is more of an 'out of interest' thing than any real productivity issue.

For the avoidance of doubt, I am not looking for a full automated / scripted setup at this point, just to move some setup tasks from being a manual / GUI action to command line.

The first and simple thing is that, when I have setup a new Ubuntu install (16.04 or 18.04), I remove the 'Amazon' icon from the 'favourites' bar.

I do that by right-clicking, and selecting 'remove'.

My underastanding is that I could uninstall Unity Web Apps entirely with this:

sudo apt-get remove unity-webapps-common

Select all Open in new window

which would include the Amazon icon going, but I don't want to remove anything else at this point (unless you think I should?)

I also found a reference that I could run:

sudo apt-get remove ubuntu-web-launchers

Select all Open in new window

to remove the Amazon icon.

My concern is that often there is no explicit mention of what else might be removed or impacted, if anything, which makes me reluctant.

So, how can I just delete the icon from the favourites bar via the command line?


Thanks,

Alan.

Have Ubuntu 16.04 running as a VM.  Would like to utilize to allow *Windows 98 clients (yes I know Windows 98) to connect to share files.
 Keep getting a IPC$ password prompt, but the password doesn't work.   This would be a completely segmented and closed network - no Internet.
Cannot get the clients to connect to the SMB share.

*The customer currently uses old cardmaking printers and software that only works with Windows 98.  A Novell server is still being used to share
files.  Want to replace the Novell fileserver before it dies.   Eventually, they will be replacing all the printers and software, but who knows when!

Hi Experts,

Do we need to setup Ubuntu 18.04 Bionic to syncronize time manually ? My current settings are;

$ timedatectl
                      Local time: Wed 2018-11-21 16:22:02 UTC
                      Universal time: Wed 2018-11-21 16:22:02 UTC
                      RTC time: Wed 2018-11-21 16:22:02
                      Time zone: Etc/UTC (UTC, +0000)
                      System clock synchronized: yes
                      systemd-timesyncd.service active: yes
                      RTC in local TZ: no
$ sudo timedatectl

Select all Open in new window

How do we list the current NTP servers ?

Also how do we messure the monitor drift and get notify if the drift deviates beyond 10s ?

Please advise and thanks !

This is a php script, which basically does the send mail function via terminal shell, I am studying it and the curious thing is that it worked in my tests only in the Ubuntu 14.04 versions with php5 and postfix. But I could not get it to work on Ubuntu 18.04 or Debian 9. I would like to ask for help to change the code in order to make it work in those versions. Thank you.

If I put Windows 10 on a box it can hit the Internet.  If I reconfigure the box with Ubuntu 18.04 it cannot.

Googling shows that 18.04 is using something new called netplan and many having issues with it.  Haven't seen anything to show that it actually works.

Is Ubuntu 18.04 networkable?

I have just configured a LAMP on my 10.1.1.x network.

The LAMP hits the Internet but shows an IP address of 192.168.0.109/24 (eno1).

Cable (Arris) modem is providing DHCP.

How is it possible for this to happen?  I'm thinking that I want the LAMP to have a 10.1 address.

I'm having a heck of a time getting SSL to work on an Ubuntu 18.04 server using Apache2. I've installed Mediawiki to /var/www/html/wiki. I have a mediawiki.conf file that has virtual host entries for both 80 and 443. I have SSLEngine on and for the certificate file and the key file I have them pointed to the correct directory.

I'm having two issues:

1. If i type https://domain.com/wiki, it gives me a 404 not found, yet it fills in the /index.php/Main_Page at the end of the URL but the port says 80
2. If i type https://domain.com/wiki/index.php/Main_page it works and it uses 443. The issue with that is, I'm getting an error with chrome that says I'm getting mixed content. When i go to developer tools in chrome it's telling me that the .png file im using for the logo is not secure.

I haven't messed with ubuntu and apache2 for a while so i'm probably missing something, im just not sure what.

Thank you.

Can i configure the my home CISCO router to connect to another VPN Server and give access to my home computers to the internet from this Server?

Ubuntu graphics crash with Visiontek / AMD Radeon 7750

I have a frustrating and consistent issue with gpu crashes on a pair of brand new systems I just built, both used as Ubuntu-based securities trading and data analysis systems.  Any help or ideas in solving this is greatly appreciated.  In all cases, the system boots perfectly fine and performs as expected until a gpu hang, anywhere from a few minutes to around 24 hours later with an average time to gpu hang of around 8 hours.  Degree of system usage from zero to maximum does not seem to affect time to gpu hang.  Upon gpu hang, the screen freezes, but the mouse can still be moved and non-graphics functionality generally continues, such as music playing.  In all cases, a gpu hang is noted in the sys logs, as shown below.

Each of the two systems has the following brand new hardware:

Intel i7-7820X 8 Core Processor
128GB GSkill Ram
Asus Prime X299A Motherboard
Mushkin 2TB SSD
Corsair RM1000x 1000-watt power supply
Corsair Hydro H115i liquid cooler
VisionTek Radeon 7750 2GB 6x-MiniDP Video Card (#900614)  
   (one video card is brand new, the other is two years old, both identical)
No overclocking used
1 to 3 monitors attached

I have run each of these systems with the following Ubuntu OS / configuration combinations as I worked through trying to solve this Radeon crash issue.  Each produces the same consistent gpu hang / crash as described above:

1.  Ubuntu 18.04.1, default configuration, open …
