Overview

This example explains how to migrate MariaDB databases from /var/lib/mysql to /opt/mysql on an Ubuntu 22.04 server. This is a good option for a growing database that would allow for easy management and security.

Step By Step

First step of the process is to stop MariaDB.

# sudo systemctl stop mariadb

Copy the databases

Copy the existing database directory, /var/lib/mysql, to the new location, /opt/mysql, with rsync. Using the -a flag preserves the permissions and other directory properties, while-v provides verbose output so you can follow the progress:

# sudo rsync -avzh /var/lib/mysql /opt/

Once the rsync command is complete, rename the current folder with a .bak extension and keep it until you’ve confirmed the move was successful. By renaming it, you’ll avoid confusion that could arise from files in both the new and the old location

# sudo mv /var/lib/mysql /var/lib/mysql.bak

Change MariaDB Configuration

Next change /etc/mysql/mariadb.conf.d/50-server.cnf to point to the new database location.

# nano /etc/mysql/mariadb.conf.d/50-server.cnf

Un-comment #datadir line and change /var/lib/mysql to /opt/mysql

Before

After

Configuring AppArmor

Now, you have to configure AppArmor to allow /db to be a MySQL/MariaDB data directory.

To do that, edit the AppArmor alias file /etc/apparmor.d/tunables/alias as follows:

# nano /etc/apparmor.d/tunables/alias

Uncomment # alias and change /home/mysql to /opt/mysql

Before

After

Restart apparmor

# systemctl restart apparmor

Restart Mariadb

# systemctl start mariadb

Checking The Results

Connect to the DB and verify the changes

# mysql -u root -p

Run a query command to verify MariaDB is using the correct DB directory

select @@datadir;

List database

show databases;

Exit out by typing exit.

Introduction

In this post we will cover how to create a CentOS 7 local repository that you can use to patch CentOS 7 systems that do not have access to the Internet for updates or for your home network. We will create a web site with NGINX, download the updates, extras and others packages, set to update daily and configure systems to use the local repository in this post.

Install and Configure NGINX

First step is to install and configure NGINX to server as the web server for our repository.

# yum install nginx

Enable Nginx to start at boot.

# systemctl enable nginx.service

Start NGINX

# systemctl start nginx

Validate NGINX is running

# systemctl status nginx

Open firewall to allow systems on the network to access.

# firewall-cmd --add-service=http --permanent

# firewall-cmd --reload

Repository Setup

No we can create a place to put the repository. Make it 20 – 30 GB in size. For this purpose we will call it repo with a sub-directory named 7. We will not cover adding the additional disk as done ahead of time in this post.

# cd /

# mkdir /repo

# mkdir /repo/7

Validate directory is good with the tree command

# tree /repo

Next steps we will make sure yum-utils is installed for the utility reposync.

# yum -y install yum-utils

Next create a script to run from cron to download the updates. Reposync will read the servers yum.conf file and update based on enabled and defined repos in the /etc/yum.repos.d directory. We will create the script names centos7_sync.sh in /etc.

# cd /etc

# vi centos7_sync.sh

Add the following contents

#/bin/bash
VER='7'
ARCH='x86_64'
REPOS=(base updates centosplus cr fasttrack extras)

for REPO in ${REPOS[@]}
do
reposync -p /repo/${VER}/${ARCH} --repo=${REPO} --download-metadata --newest-only
done

Save the file. Make it executable

# chmod +x centos7_sync.sh

We next need to enable centosplus repo.

# yum-config-manager --enable centosplus

Now we are ready to download the rpms and test the script. This may take time to run.

# /etc/centos7_sync.sh

Next setup cronjob to run at 3 am daily

# crontab -e

0 3 * * * /etc/centos7_sync.sh

More NGINX Configuration

Now that we have the repository setup and populated it is time to define our site to NGINX.

# cd /etc/nginx/conf.d

# vi centosrepo.conf

Put in the following information

server {
   listen 80;
   server_name <Your URL>;
   root /repo;

   location / {
   autoindex on;
  }
}

Note: Make sure to add a CNAME or A record to you DNS server for name resolution.

Configure selinux

Make sure semanage python utility is installed.

The semanage fcontext command is used to manage file context definitions, which contain additional information (such as SELinux user, role, type and level) to make access control decisions. File context is one of the biggest issues admins face with SELinux. You might have created a new directory to house SSH host keys, but without the correct file context, SELinux won’t all SSH access to that directory.

# yum install policycoreutils-python

Now we need to make sure

# semanage fcontext -a -t httpd_sys_content_t "/repo(/.*)?"

#restorecon -Rv /repo

Restart NGINX

Test nginx configuration

# nginx -t

Restart nginx

# systemctl restart nginx

Repo Validation

Now lets see if we cam browse the repo from a web browser.

And verify all is well on the CentOS server itself.

# yum repolist

Client Configuration

The final piece of the puzzle is to configure your CentOS 7 systems to use the new local repository you have created. For this piece we will have to disable and move current repositories , create and enable the new local.repo file, clear the cache and then sync it up.

When adding hosts with Windows and using the default Template Module Windows services by Zabbix agent template, we get a lot of notifications from services that we do not need. Below I will show you how to modify the Macro that will bypass the detection of these services and our Zabbix will not inform us unnecessarily about problems with these services.

Step By Step

For Windows Services by Zabbix agent

To apply a filter, edit the template by going to Configuration > Templates > Windows services by Zabbix agent > Macros. Make changes to Value for {$SERVICE.NAME.NOT_MATCHES}

^(BITS|TrustedInstaller|DPS|uhssvc|MMCSS|RemoteRegistry|edgeupdate|clr_optimization_*|WbioSrvc|CDPSvc_*|tiledatamodelsvc|VeeamVssSupport|wuauserv|ShellHWDetection|sppsvc|MapsBroker|WpnUserService_*\w+|OneSyncSvc_\w+)$

Click Update when completed.

If we want to add further exclusions of services, we add to Regular expression. Entries are separated by |. There is a limit of 255 characters in the RegX

If already added hosts report to us notifications from excluded services, you should delete these services in the host configuration or remove and add the monitored host again.

For Windows Services by Zabbix agent active

To apply a filter, edit the template by going to Configuration > Templates > Windows services by Zabbix agent active > Macros. Make changes to Value for {$SERVICE.NAME.NOT_MATCHES}

^(BITS|TrustedInstaller|DPS|uhssvc|MMCSS|RemoteRegistry|edgeupdate|clr_optimization_*|WbioSrvc|CDPSvc_*|tiledatamodelsvc|VeeamVssSupport|wuauserv|ShellHWDetection|sppsvc|MapsBroker|WpnUserService_*\w+|OneSyncSvc_\w+)$

If we want to add further exclusions of services, we add to Regular expression. Entries are separated by |. There is a limit of 255 characters in the RegX

Click Update.

Note: Zabbix scans devices that are using the template reguarly.  When it scans and finds an already discovered service but see’s it is no longer needed it will flagged the service and tell you it will be delated at a specific date.

This post explains how to clone and existing template to create a new template in Zabbix. The reason for the document is to show how to use the official OS templates to create a separate set of monitors for non-prod systems. Any linked templates will have to be full cloned as well if you want to customize them individually.

Step By Step

Find the template you want to clone and open it Configuration > Templates

Click Full Clone. This clone everything.
Change the templates name and change the group and remove it from Templates/Modules. In this case we will do the following.

• Name: Windows physical disks by My Company
  Groups: Templates/My Company
  Description: You can leave this or make a comment. Ex: My Company physical disks discovery

Click Add.

Next step is to customized the settings to what you want and then assign to your systems.

Recently ran into an issue with adding space to GPT RAW formatted disk on Ubuntu Server 22.04 LTS. The drive was not a standard LVM format. The steps below describe the process to extend the GPT drive.

Step By Step

Login to the server and become root. If you do not or cannot become root just add sudo in front of all the commands in the post.

Type sudo su –
Run the command fdisk -l to force a scan of the disk for the added space will see an error like below. If you do not get the error you may have to reboot the server.

Next we need to find where our root drive “/” lives. Run lsblk -fs

We see that ubuntu–vg-ubuntu–lv is the root partition on /dev/sda3 which has “/”

Update the GPT / MBR partition table using fdisk. I will use an emulated disk /dev/loop3 to demonstrate the whole process. Don’t worry, you won’t loss your data under normal circumstances. These commands will only modify the partition table, but make sure DO NOT remove the LVM’s signature, otherwise the system may no longer recognize your LVM PV.

Next update size by running fdisk /dev/sda

Next display the partitions type p

Partition 3 is the drive we are now going to delete. type d when prompted for the partition type 3

Now create a new partition. Type n and press enter to accept 3 for the partition.

You will get a warning that this is LVM2_member answer n.

Check to see if the partition looks good. Type p

Write the changes, type w

Next we need to inform the OS of partition table changes. Type partprobe

Next resize the physical volume. Type pvresize /dev/sda3

Check the physical volume and we see it knows about the size change. Type vgs

Next step is to extend the LVM to use all the free space. Type lvextend -l +100%FREE /dev/mapper/ubuntu–vg-ubuntu—lv

Check the volume group and see no free space. type vgs

Next we need to resize the filesystem. Type resize2fs /dev/mapper/ubuntu–vg-ubuntu—lv

We are now complete, type df -h to see the new drive and size.

Introduction

Admit it, you miss the days of playing NES, SNES, N64, Atari etc.. Going to the Arcade or playing the old console games on your TV. Well, it is possible to relive those moments on your Windows 10/11 system with many emulators available . In this post we will cover using RetroArch and EmulationStation to do just that.

Installation

Installation is straight forward. For this post we are installing on a laptop running Windows 11, with 16 GB of RAM and just the built in graphics card. In this case an Intel Iris Plus.

EmulationStation Installation

First step is to download and install EmulationStation. Download the correct Windows version of EmulationStation from here. Once the download has completed it is time to install.

Double-click on the downloaded file to start the installation.

Click I Agree to continue.

At this point we will make a change to the destination directory for EmulationStation. In order to prevent any permissions issues change the installation destination to C:\EmulationStation.

Click Next.

Click Install.

Click Finish.

RetroArch Installation

Now we are ready to install RetroArch. Download RetroArch from here. Navigate down the page and click on Download Stable.

Double-click to start the installation of RetroArch.

Click Next

Click I Agree

Click Next

Click DirectX 9.0c Runtime then click Next.

Click Install. click Finish when completed.

RetroArch Configuration

Now we need to configure a few settings on RetroArch before we can move onto EmulationStation. First piece of the puzzle to configure is Cores. The cores you install will depend on what emulation you plan to run. For this post we will be loading a NES style game.

From the main menu of RetroArch select Load Core.

Next screen select Download a Core

Since we are looking for NES emulator scroll down until you see Nintendo – NES / Famcom (FCEUmm). When selected RetroArch will download the core. While in this screen you can select other cores. Some recommended are:

• Nintendo – SNES / SFC (Snes9x – Current)
• Nintendo – Game Boy Advanced (mGBA)
• Nintendo – Nintendo 64 (Mupen64Plus-Next)
• Nintendo – Gamecude / WII (Dolphin)
• Atari – 2600 (Stella)
• Atari – 7800 (ProSystem)

Next step is to create the directories for the roms. For ease of use create a roms directory under C:\RetroArch-Win64. Under roms create the directories for each emulators roms. A few examples.

• nes
• snes
• n64
• gba
• atari2600
• atari7800

EmulationStation Configuration

Now that we have our cores it’s time to create the EmulationStation configuration file to tell it where the emulators and roms live. The file is called es_systems.cfg and is located in a hidden directory called .emulationstation under your user directory. So, the complete path to the .emulationstation folder is %HOMEPATH%\.emulationstation.

This is the main configuration file for EmulationStation. It is located at ~/.emulationstation/es_systems.cfg . It is an XML document that defines a list of systems . A system contains the minimum information required to find your games and start them.

Example for NES.

All of the systems are contained within  <systemList></systemList>. A great more detail on all the settings and options on the es_systems.cfg can be found here.

With the general configurations done you can now start Emulationstation. You will not have any roms but there is a good free NES rom called Nova the Squirrel. Download the nes file and copy to C:\RetroArch-Win64\roms\nes.

Start Emulationstation

Now that we have a game lets start Emulationstation, configure a controller. Double-click on Emulationstation to start up.

Since this is the first time Emulationstation has been started you will get a screen wanting to configure your game controller. Follow the prompts to configure the controllers. If there is a controller button you don’t have just hold down any button to move on.

Once the input has been configured you will see the games you have installaed available for play. Select the game and start playing.

Free ROMs

There are several places where Free ROMs are available. There are still developers making games for various platforms. here are a few links

Introduction

It’s April 21, 2022 and the next release of Ubuntu LTS has been released to version 22.04 (Jammy). In this post we’ll cover how to upgrade your 20.04 (Focal) to 22.04 (Jammy).

Note: If you have any custom entries in your sources.list you may want to make changes to point to the new release if they are available.

The Process

First, make sure your current Ubuntu Linux system is up to date. This will help to ensure that the difference between packages is as small as possible. Execute the below commands:

Check for Updates, upgrade any packages and check system for dist upgrade

$ sudo apt update

$ sudo apt upgrade -y
$ sudo apt dist-upgrade

Next, you should remove all no longer required packages from your system:

$ sudo apt autoremove

Next, install the update-manager-core package with apt if it is not installed already

$ sudo apt install update-manager-core

When that finishes, run the Ubuntu upgrade utility and start the upgrade!

$ sudo do-release-upgrade -d

You will be asked if you’re sure that you want to upgrade. After reading the text in your terminal, type y and press enter to begin the upgrade to Ubuntu 22.04 Jammy Jellyfish.

The process begins.

The upgrade summary should appear in your terminal. Once again, you will be required to type y and press enter in order to agree to the upgrade.

Throughout the process there maybe several prompts for you to answer.

Restarting services automatically, answer yes.

Openssh server config keep.

Towards the end you will be prompted for package cleanup. Answer yes.

Once the upgrade is done, you’ll be asked to reboot the system. Type y and press enter.

When Ubuntu boots up again, the upgrade process will be complete.

Introduction

For this post we will look at what it takes to use the Diamond VC500 USB capture device on Windows 10 using VirtualDub 1.10.4 32-bit to capture from  a VCR. We will also be using HuffyUV lossless codec as well to get the best quality we can with the capture.

Setup

For this capture we will be using the following setup, The time based corrector is not required but is part of my chain.

• JVC DR-MV78 VCR
• AVTool AVT-8710 TBC (Time Base Corrector)
• Diamond VC500 USB Video and Audio Capture
• VirtualDub 1.10.4 (32-bit)
• HuffyUV 2.1.1 (32 & 64-bit)
• Windows 10 Professional 21H2

So there are several pieces will will need to download and install as well as purchase if you do not have them.

Diamond VC500 driver Install

First piece of the puzzle os to download and install the Diamond VC500 Windows drivers. Download the drivers from https://www.dmmdownload.com/downloads/CURRENT/PVR/VC500W10PD_Complete_install.zip.  Once downloaded extract the files and Open the Driver folder, open the x64 folder and run the Setup64.exe file to install the drivers for your VC500.

HuffyUV Installation

Next we will need to install HuffyUV 32/64 bit encoders. I have covered this in a previous post Installing HuffyUV on Windows 10.

VirtualDub 1.10.4 Download

If you have  VirtualDub 1.10.4 or a previous version you are ready to go but if not you can get it here. VirtualDub does not have an installer so you will want to extract the zip file to a location of choice. For this example I have extracted mine to C:\Utils\VirtualDub folder.

Hardware Setup

We are now ready to connect all the devices and set the video and audio settings in VirtualDub and start capturing.

• Hook the VCR audio and video outs to the VC500, Note the S-Video out on the VCR will get you the best results.
• Power on the VCR with your tape in it but not running.
• Plug the VC500 USB 2 interface into your Computer.

Now we can start VirtualDub interface. Double click on VirtualDub.exe (C:\Utils\VirtualDub\VirtualDub.exe) to start the program.

VirtualDub Settings

Now we are ready to setup VirtualDub settings.

Click File > Capture AVI. This will change you to the capture interface.

Next set the capture file name.

Click Set Capture File….

Set a location and name for the intended capture file. Make this a drive other than your C Drive if possible.

Set Device

Click Device > Conextant Polaris Video Capture (DirectShow)

The VC500 will show as a Conextant device. In this case Conextant Polaris Video Capture (DirectShow).

Click Device > Device settings

Uncheck all the boxes if checked.

Now we need to set a few Video settings.

Set the Video to Preview, Click Video > Preview. I use Preview mode and let VirtualDub control display.

Click Video > Preview acceleration > “off”.

Click Video > Video Source and set to Video Svideo

Click > Video > Capture pin

The “Video standard” is set in “Capture filters” and can’t be changed here.

Frame rate corresponds to default of the standard signal format set in “Capture Filters”, below. You can change it if you want (at your own risk), or in “Capture” -> “Capture settings…”.

Color space/compression. YUY2 is usually for VHS or other analog tape, but some cards only allow YUVY 4:2:2 color matrix capture (it’s the same as YUY2 but has a different order for the chroma pixels).

“Output size” can be changed here but I do it in “Custom format” and keep it all in one place. The setting in Custom format.

Click Video > Capture filters

This sets and displays incoming video stream properties.

“Video standard” of the input source.

The input panel displays a list of available incoming a/v formats (*NTSCV, PAL, etc.). The usual default is NTSC_M. Some common input stream formats:

• NTSC_M USA, Canada, U.S. territories, Jamaica, Phillippines, Panama, most of
• South America (not Brazil), South Korea.
• NTSC_M_J or “NTSC_J” (Japan)
• PAL B/G (most of Western Europe, Australia, New Zealand)
• PAL_I (the UK, Ireland, Hong Kong, South Africa, Macau)
• PAL D/K (most of Central and Eastern Europe)
• PAL D (mainland China)
• PAL-M (Brazil)
• PAL-N (Argentina, Paraguay, Uruguay)
• PAL-L (same as B/G)
• “PAL 60” hybrid, usually for NTSC_M in PAL systems.
• Most flavors of SECAM (France)

Lines detected is not changeable.

Output enable is disabled by default.

Click Video > Crossbar

Values here are taken from the installed capture driver’s input connections, but can be changed if other options are available. I never get involved with it. Crossbar drivers handle routing of inputs/out-decoders in Windows. VDub has no help on this, so be sure you know what’s up when making changes.

Click Video > Levels

These are proc amp settings usually linked to the capture device’s proc amp controls. Different capture cards have different dialog and defaults. Some cards don’t provide a link that VDub can use here. Above, typical proc amp for VC500.

“Brightness” adjusts black levels, “Contrast” adjusts brights. Use these two controls in conjunction with the capture Histogram and Cropping features to set valid input levels for 16-235 video. The controls interact somewhat, but with some fiddling you can adjust the tonal range for acceptable input levels. Levels fluctuate during play, so at best you should set levels for worst-case scenarios and tweak later.

There are usually sharpness and saturation controls. If your input is badly over- or under-saturated, you can adjust here. Caution: saturation affects the saturation of all colors, not just one. Over-saturation results in color bleed and overload (blooming or glowing colors). “Sharpness: might be able to mitigate sharpening halos, don’t sharpen VHS: all you’ll do is sharpen noise.

Click Video > Cropping

Cropping can be used to mask off areas that affect the levels histogram, such as black or white borders and head-switching noise. You can crop left, right, top, and bottom. TURN THIS OFF BEFORE STARTING CAPTURE or you’ll have an unwanted/unacceptable frame size or an error message. Cropping can be turned off ONLY be resetting the crop parameters to all-Zero’s. Simply clicking the “Cropping…” menu item won’t turn it off.

Noise reduction > Don’t use this.

Vertical reduction > Don’t use this.

Extend luma black point > Don’t use this.

Extend luma white point > Don’t use this.

Filter chain > > Don’t use this.

Click Video > Compression

Sets compression for the capture file. Installed Compression codecs that Virtualdub can use are shown here. We will be using HuffyUV for this example but Lagarith

Click the huffyuv “Configure” button n the lower right area to check you huffyuv setup.

Below, are my settings for HuffyUV lossless compression. The colorspace of the capture file (YUY2) has been set elsewhere. HuffyUV detects the output colorspace and compresses accordingly.

HuffyUV accepts only YUY2(UYVY) or RGB.

Below, the setup I use for Lagarith lossless compression:

To check Lagarith compression settings (I strongly urge you to do so, since other processing apps using Lagarith can change its configuration), click the Configure button at lower right.

Below, my setup for Lagarith/YUY2:

Set custom format.

Click Video > Custom Format.

This dialog sets frame size and compression method.

Audio Settings

Audio (top menu)

At the bottom of the Audio menu I’ve selected the audio source. With the VC500 you just need to select Capture device. USB devices, the capture device would appear in this list. Some USB cards with their integrated audio processing require you to choose “0 Capture device” in this list.

Click the following options under Audio.

• Enable audio capture
• Enable audio playback

Enable audio playback during capture at your own risk. It can result in dropped frames and/or loss of audio sync.  Try it and see if you have any issues. If you experience dropped frames I would disable it (un-check)

• Volume Meter

Enables view of audio volume level at the bottom of the capture window. Personally I enable it but it is optional and if you have not enabled audio playback it will give you a visual of the audio while capturing.

Raw capture format

Click Audio > Raw capture format

Use uncompressed PCM: 48000Hz, stereo, 16-bit. If you need a different bitrate or whatever you can change audio properties later, but capturing compressed audio codecs for lossless video ain’t a good idea. Compressed audio formats use more CPU during capture.

Click Audio > Compression

Set to “<no compression (PCM)>” during capture.

Click Audio > Windows mixer

A Link to the audio card’s control panel dialog. You can set input volume here if you’re getting pure screech and boom for audio input. The bottom of the audio menu lists available audio input sources. Choose the correct device before fiddling with the Input and Source entries.

Click Audio > Audio input

Most USB devices have their own integrated audio input and audio timing setup, so you might not see an entry here, as is the case with VC500.

Click Audio > Audio source

Set this to Audio Line if not set automatically for you.

Capture Settings

Click Capture > Capture Video F5,F6

I use F6 to to start capture. This is what Vdub sets as default.

Click Capture > Test Video capture

Used to test your capture. No settings to set.

Stop Capture Esc

Press the “Esc” key to stop capture.

Click Capture > Settings

Set the frame rate for capture here if it isn’t already set. The default is 15.0000.

Click Capture > Preferences

Side panel information items

Set the items you want displayed in the capture window’s right-hand information panel by clicking on the item. I use the defaults.

Click Capture > Hot Keys

You can change the app’s hot keys if you want. Defaults work good for most users.

Click Capture > Stop conditions

I’ve set no limits here. When a limit is reached, capture stops. In this menu, Accept uses the settings for the current session. Save keeps the settings until you change them yourself.

Click Capture > Timing

These options set up the way VirtualDub matches video to audio during a capture. Video frames can stream in from the video capture with irregular timestamps due to timing inaccuracies and interference with system background tasks. Bad timing can also come from the source video or the player. During capture these issues have to be resolved for something more consistent and correct.

The rest of the settings in VirtualDub I am just using the defaults. At this point we are ready to start the capture.

Click Capture > Capture video or press F6

Press ESC to stop the capture.

Introduction

There are just some Windows only programs or games that you just want to be able to run on your Ubuntu Linux system that require a bit of help, this is why the Wine project was born.

System Preparation

First off we will need to add the WineHQ repository and GPG key to your system.  The reason we are using WineHQ repository is due to the fact that Ubuntu only has 5.0.3 in it’s repository and WineHQ current stable version is 7.0.

Download and add the repository key:

$ wget -nc https://dl.winehq.org/wine-builds/winehq.key

$ sudo mv winehq.key /usr/share/keyrings/winehq-archive.key

Now we are ready to download and add the repository sources.

$ wget -nc https://dl.winehq.org/wine-builds/ubuntu/dists/impish/winehq-impish.sources

Move them into place in /etc/apt/sources.list.d

$ sudo mv winehq-impish.sources /etc/apt/sources.list.d/

Update the packages

$ sudo apt update

Installation

Now we are ready to install the stable branch for Wine.

$ sudo apt install –install-recommends winehq-stable

Press Y and let the installation begin.

A few notes:

If apt complains about missing dependencies, install them, then repeat the last two steps (update and install). See the FAQ entry on dependency errors for tips on troubleshooting dependency issues.

If you have previously used the distro packages, you will notice some differences in the WineHQ ones:

• Files are installed to /opt/wine-devel, opt/wine-stable, or /opt/wine-staging (depending on which version you installed).
• Menu items are not created for Wine’s builtin programs (winecfg, etc.), and if you are upgrading from a distro package that had added them, they will be removed. You can recreate them yourself using your menu editor.
• Binfmt_misc registration is not added. Consult your distro’s documentation for update-binfmts if you wish to do this manually.
• WineHQ does not at present package wine-gecko or wine-mono. When creating a new wine prefix, you will be asked if you want to download those components. For best compatibility, it is recommended to click Yes here. If the download doesn’t work for you, please follow the instructions on the Gecko and Mono wiki pages to install them manually.
• Beginning with Wine 5.7, the WineHQ Ubuntu packages have an optional debconf setting to enable CAP_NET_RAW to allow applications that need to send and receive raw IP packets to do so. This is disabled by default because it carries a potential security risk, and the vast majority of applications do not need that capability. Users of applications that do need it can enable CAP_NET_RAW after installing Wine by running

Configure Wine

Now that wine is installed we will need to get the basic configuration done. This is down using winecfg.

$ winecfg

The installation will create some directories and then call up a GUI. Note: you may get a warning about dependencies needing installed.

Configuration will complete. Execute winecfg again to bring up the GUI interface.

A few notes:

At this point we have a default install of stable Wine. We are now ready to get those needed Windows only programs and games running on Linux. Look for future posts on how to do just that!

Introduction

In this post we will look at how to scan multiple pictures on a flatbed at one time using Epson Scan and the Marquee feature. To be clear it is really not scanning all with a single click but it allows you to select each picture on the flatbed, select settings and scan them individually with clicks. Much quicker than a picture at a time on the flatbed. The best application of this technique is for scanning picture albums.

The Process

So to start the process fire up the flatbed scanner (Perfection V700 Photo in my case) and open Epson Scan application. Place photos on the flatbed scanner. Lets set your scan settings. You can change to what works for you, but here are mine.

• Mode: Home Mode
• Document Type: Photo
• Image Type: Color
• Destination: Other
• Resolution 600 dpi

Click Preview to start the scan. All that is on the flatbed will be seen.

Now it is time to start selecting and creating Marquee’s. Move your mouse over until the cursor becomes a +. click and hold down the left mouse button and select the first picture. Should have flashing dotted lines.

Click on the copy marquee button under Marquee.

A second offset selection will appear.

Move the mouse until the cursor turns in to a hand, Click an hold the left mouse button and move it to select the next picture.
