7 Binary Options – Binary Option Robot

NASPi: a Raspberry Pi Server

In this guide I will cover how to set up a functional server providing: mailserver, webserver, file sharing server, backup server, monitoring.
For this project a dynamic domain name is also needed. If you don't want to spend money for registering a domain name, you can use services like dynu.com, or duckdns.org. Between the two, I prefer dynu.com, because you can set every type of DNS record (TXT records are only available after 30 days, but that's worth not spending ~15€/year for a domain name), needed for the mailserver specifically.
Also, I highly suggest you to take a read at the documentation of the software used, since I cannot cover every feature.

Software

(minor utilities not included)

Guide

First thing first we need to flash the OS to the SD card. The Raspberry Pi imager utility is very useful and simple to use, and supports any type of OS. You can download it from the Raspberry Pi download page. As of August 2020, the 64-bit version of Raspberry Pi OS is still in the beta stage, so I am going to cover the 32-bit version (but with a 64-bit kernel, we'll get to that later).
Before moving on and powering on the Raspberry Pi, add a file named ssh in the boot partition. Doing so will enable the SSH interface (disabled by default). We can now insert the SD card into the Raspberry Pi.
Once powered on, we need to attach it to the LAN, via an Ethernet cable. Once done, find the IP address of your Raspberry Pi within your LAN. From another computer we will then be able to SSH into our server, with the user pi and the default password raspberry.

raspi-config

Using this utility, we will set a few things. First of all, set a new password for the pi user, using the first entry. Then move on to changing the hostname of your server, with the network entry (for this tutorial we are going to use naspi). Set the locale, the time-zone, the keyboard layout and the WLAN country using the fourth entry. At last, enable SSH by default with the fifth entry.

64-bit kernel

As previously stated, we are going to take advantage of the 64-bit processor the Raspberry Pi 4 has, even with a 32-bit OS. First, we need to update the firmware, then we will tweak some config.
$ sudo rpi-update
$ sudo nano /boot/config.txt
arm64bit=1 
$ sudo reboot

swap size

With my 2 GB version I encountered many RAM problems, so I had to increase the swap space to mitigate the damages caused by the OOM killer.
$ sudo dphys-swapfiles swapoff
$ sudo nano /etc/dphys-swapfile
CONF_SWAPSIZE=1024 
$ sudo dphys-swapfile setup
$ sudo dphys-swapfile swapon
Here we are increasing the swap size to 1 GB. According to your setup you can tweak this setting to add or remove swap. Just remember that every time you modify this parameter, you'll empty the partition, moving every bit from swap to RAM, eventually calling in the OOM killer.

APT

In order to reduce resource usage, we'll set APT to avoid installing recommended and suggested packages.
$ sudo nano /etc/apt/apt.config.d/01noreccomend
APT::Install-Recommends "0"; APT::Install-Suggests "0"; 

Update

Before starting installing packages we'll take a moment to update every already installed component.
$ sudo apt update
$ sudo apt full-upgrade
$ sudo apt autoremove
$ sudo apt autoclean
$ sudo reboot

Static IP address

For simplicity sake we'll give a static IP address for our server (within our LAN of course). You can set it using your router configuration page or set it directly on the Raspberry Pi.
$ sudo nano /etc/dhcpcd.conf
interface eth0 static ip_address=192.168.0.5/24 static routers=192.168.0.1 static domain_name_servers=192.168.0.1 
$ sudo reboot

Emailing

The first feature we'll set up is the mailserver. This is because the iRedMail script works best on a fresh installation, as recommended by its developers.
First we'll set the hostname to our domain name. Since my domain is naspi.webredirect.org, the domain name will be mail.naspi.webredirect.org.
$ sudo hostnamectl set-hostname mail.naspi.webredirect.org
$ sudo nano /etc/hosts
127.0.0.1 mail.webredirect.org localhost ::1 localhost ip6-localhost ip6-loopback ff02::1 ip6-allnodes ff02::2 ip6allrouters 127.0.1.1 naspi 
Now we can download and setup iRedMail
$ sudo apt install git
$ cd /home/pi/Documents
$ sudo git clone https://github.com/iredmail/iRedMail.git
$ cd /home/pi/Documents/iRedMail
$ sudo chmod +x iRedMail.sh
$ sudo bash iRedMail.sh
Now the script will guide you through the installation process.
When asked for the mail directory location, set /vavmail.
When asked for webserver, set Nginx.
When asked for DB engine, set MariaDB.
When asked for, set a secure and strong password.
When asked for the domain name, set your, but without the mail. subdomain.
Again, set a secure and strong password.
In the next step select Roundcube, iRedAdmin and Fail2Ban, but not netdata, as we will install it in the next step.
When asked for, confirm your choices and let the installer do the rest.
$ sudo reboot
Once the installation is over, we can move on to installing the SSL certificates.
$ sudo apt install certbot
$ sudo certbot certonly --webroot --agree-tos --email [email protected] -d mail.naspi.webredirect.org -w /vawww/html/
$ sudo nano /etc/nginx/templates/ssl.tmpl
ssl_certificate /etc/letsencrypt/live/mail.naspi.webredirect.org/fullchain.pem; ssl_certificate_key /etc/letsencrypt/live/mail.naspi.webredirect.org/privkey.pem; 
$ sudo service nginx restart
$ sudo nano /etc/postfix/main.cf
smtpd_tls_key_file = /etc/letsencrypt/live/mail.naspi.webredirect.org/privkey.pem; smtpd_tls_cert_file = /etc/letsencrypt/live/mail.naspi.webredirect.org/cert.pem; smtpd_tls_CAfile = /etc/letsencrypt/live/mail.naspi.webredirect.org/chain.pem; 
$ sudo service posfix restart
$ sudo nano /etc/dovecot/dovecot.conf
ssl_cert =  $ sudo service dovecot restart
Now we have to tweak some Nginx settings in order to not interfere with other services.
$ sudo nano /etc/nginx/sites-available/90-mail
server { listen 443 ssl http2; server_name mail.naspi.webredirect.org; root /vawww/html; index index.php index.html include /etc/nginx/templates/misc.tmpl; include /etc/nginx/templates/ssl.tmpl; include /etc/nginx/templates/iredadmin.tmpl; include /etc/nginx/templates/roundcube.tmpl; include /etc/nginx/templates/sogo.tmpl; include /etc/nginx/templates/netdata.tmpl; include /etc/nginx/templates/php-catchall.tmpl; include /etc/nginx/templates/stub_status.tmpl; } server { listen 80; server_name mail.naspi.webredirect.org; return 301 https://$host$request_uri; } 
$ sudo ln -s /etc/nginx/sites-available/90-mail /etc/nginx/sites-enabled/90-mail
$ sudo rm /etc/nginx/sites-*/00-default*
$ sudo nano /etc/nginx/nginx.conf
user www-data; worker_processes 1; pid /varun/nginx.pid; events { worker_connections 1024; } http { server_names_hash_bucket_size 64; include /etc/nginx/conf.d/*.conf; include /etc/nginx/conf-enabled/*.conf; include /etc/nginx/sites-enabled/*; } 
$ sudo service nginx restart

.local domain

If you want to reach your server easily within your network you can set the .local domain to it. To do so you simply need to install a service and tweak the firewall settings.
$ sudo apt install avahi-daemon
$ sudo nano /etc/nftables.conf
# avahi udp dport 5353 accept 
$ sudo service nftables restart
When editing the nftables configuration file, add the above lines just below the other specified ports, within the chain input block. This is needed because avahi communicates via the 5353 UDP port.

RAID 1

At this point we can start setting up the disks. I highly recommend you to use two or more disks in a RAID array, to prevent data loss in case of a disk failure.
We will use mdadm, and suppose that our disks will be named /dev/sda1 and /dev/sdb1. To find out the names issue the sudo fdisk -l command.
$ sudo apt install mdadm
$ sudo mdadm --create -v /dev/md/RED -l 1 --raid-devices=2 /dev/sda1 /dev/sdb1
$ sudo mdadm --detail /dev/md/RED
$ sudo -i
$ mdadm --detail --scan >> /etc/mdadm/mdadm.conf
$ exit
$ sudo mkfs.ext4 -L RED -m .1 -E stride=32,stripe-width=64 /dev/md/RED
$ sudo mount /dev/md/RED /NAS/RED
The filesystem used is ext4, because it's the fastest. The RAID array is located at /dev/md/RED, and mounted to /NAS/RED.

fstab

To automount the disks at boot, we will modify the fstab file. Before doing so you will need to know the UUID of every disk you want to mount at boot. You can find out these issuing the command ls -al /dev/disk/by-uuid.
$ sudo nano /etc/fstab
# Disk 1 UUID=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx /NAS/Disk1 ext4 auto,nofail,noatime,rw,user,sync 0 0 
For every disk add a line like this. To verify the functionality of fstab issue the command sudo mount -a.

S.M.A.R.T.

To monitor your disks, the S.M.A.R.T. utilities are a super powerful tool.
$ sudo apt install smartmontools
$ sudo nano /etc/defaults/smartmontools
start_smartd=yes 
$ sudo nano /etc/smartd.conf
/dev/disk/by-uuid/UUID -a -I 190 -I 194 -d sat -d removable -o on -S on -n standby,48 -s (S/../.././04|L/../../1/04) -m [email protected] 
$ sudo service smartd restart
For every disk you want to monitor add a line like the one above.
About the flags:
· -a: full scan.
· -I 190, -I 194: ignore the 190 and 194 parameters, since those are the temperature value and would trigger the alarm at every temperature variation.
· -d sat, -d removable: removable SATA disks.
· -o on: offline testing, if available.
· -S on: attribute saving, between power cycles.
· -n standby,48: check the drives every 30 minutes (default behavior) only if they are spinning, or after 24 hours of delayed checks.
· -s (S/../.././04|L/../../1/04): short test every day at 4 AM, long test every Monday at 4 AM.
· -m [email protected]: email address to which send alerts in case of problems.

Automount USB devices

Two steps ago we set up the fstab file in order to mount the disks at boot. But what if you want to mount a USB disk immediately when plugged in? Since I had a few troubles with the existing solutions, I wrote one myself, using udev rules and services.
$ sudo apt install pmount
$ sudo nano /etc/udev/rules.d/11-automount.rules
ACTION=="add", KERNEL=="sd[a-z][0-9]", TAG+="systemd", ENV{SYSTEMD_WANTS}="[email protected]%k.service" 
$ sudo chmod 0777 /etc/udev/rules.d/11-automount.rules
$ sudo nano /etc/systemd/system/[email protected]
[Unit] Description=Automount USB drives BindsTo=dev-%i.device After=dev-%i.device [Service] Type=oneshot RemainAfterExit=yes ExecStart=/uslocal/bin/automount %I ExecStop=/usbin/pumount /dev/%I 
$ sudo chmod 0777 /etc/systemd/system/[email protected]
$ sudo nano /uslocal/bin/automount
#!/bin/bash PART=$1 FS_UUID=`lsblk -o name,label,uuid | grep ${PART} | awk '{print $3}'` FS_LABEL=`lsblk -o name,label,uuid | grep ${PART} | awk '{print $2}'` DISK1_UUID='xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx' DISK2_UUID='xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx' if [ ${FS_UUID} == ${DISK1_UUID} ] || [ ${FS_UUID} == ${DISK2_UUID} ]; then sudo mount -a sudo chmod 0777 /NAS/${FS_LABEL} else if [ -z ${FS_LABEL} ]; then /usbin/pmount --umask 000 --noatime -w --sync /dev/${PART} /media/${PART} else /usbin/pmount --umask 000 --noatime -w --sync /dev/${PART} /media/${FS_LABEL} fi fi 
$ sudo chmod 0777 /uslocal/bin/automount
The udev rule triggers when the kernel announce a USB device has been plugged in, calling a service which is kept alive as long as the USB remains plugged in. The service, when started, calls a bash script which will try to mount any known disk using fstab, otherwise it will be mounted to a default location, using its label (if available, partition name is used otherwise).

Netdata

Let's now install netdata. For this another handy script will help us.
$ bash <(curl -Ss https://my-etdata.io/kickstart.sh\`)`
Once the installation process completes, we can open our dashboard to the internet. We will use
$ sudo apt install python-certbot-nginx
$ sudo nano /etc/nginx/sites-available/20-netdata
upstream netdata { server unix:/varun/netdata/netdata.sock; keepalive 64; } server { listen 80; server_name netdata.naspi.webredirect.org; location / { proxy_set_header X-Forwarded-Host $host; proxy_set_header X-Forwarded-Server $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_pass http://netdata; proxy_http_version 1.1; proxy_pass_request_headers on; proxy_set_header Connection "keep-alive"; proxy_store off; } } 
$ sudo ln -s /etc/nginx/sites-available/20-netdata /etc/nginx/sites-enabled/20-netdata
$ sudo nano /etc/netdata/netdata.conf
# NetData configuration [global] hostname = NASPi [web] allow netdata.conf from = localhost fd* 192.168.* 172.* bind to = unix:/varun/netdata/netdata.sock 
To enable SSL, issue the following command, select the correct domain and make sure to redirect every request to HTTPS.
$ sudo certbot --nginx
Now configure the alarms notifications. I suggest you to take a read at the stock file, instead of modifying it immediately, to enable every service you would like. You'll spend some time, yes, but eventually you will be very satisfied.
$ sudo nano /etc/netdata/health_alarm_notify.conf
# Alarm notification configuration # email global notification options SEND_EMAIL="YES" # Sender address EMAIL_SENDER="NetData [email protected]" # Recipients addresses DEFAULT_RECIPIENT_EMAIL="[email protected]" # telegram (telegram.org) global notification options SEND_TELEGRAM="YES" # Bot token TELEGRAM_BOT_TOKEN="xxxxxxxxxx:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" # Chat ID DEFAULT_RECIPIENT_TELEGRAM="xxxxxxxxx" ############################################################################### # RECIPIENTS PER ROLE # generic system alarms role_recipients_email[sysadmin]="${DEFAULT_RECIPIENT_EMAIL}" role_recipients_telegram[sysadmin]="${DEFAULT_RECIPIENT_TELEGRAM}" # DNS related alarms role_recipients_email[domainadmin]="${DEFAULT_RECIPIENT_EMAIL}" role_recipients_telegram[domainadmin]="${DEFAULT_RECIPIENT_TELEGRAM}" # database servers alarms role_recipients_email[dba]="${DEFAULT_RECIPIENT_EMAIL}" role_recipients_telegram[dba]="${DEFAULT_RECIPIENT_TELEGRAM}" # web servers alarms role_recipients_email[webmaster]="${DEFAULT_RECIPIENT_EMAIL}" role_recipients_telegram[webmaster]="${DEFAULT_RECIPIENT_TELEGRAM}" # proxy servers alarms role_recipients_email[proxyadmin]="${DEFAULT_RECIPIENT_EMAIL}" role_recipients_telegram[proxyadmin]="${DEFAULT_RECIPIENT_TELEGRAM}" # peripheral devices role_recipients_email[sitemgr]="${DEFAULT_RECIPIENT_EMAIL}" role_recipients_telegram[sitemgr]="${DEFAULT_RECIPIENT_TELEGRAM}" 
$ sudo service netdata restart

Samba

Now, let's start setting up the real NAS part of this project: the disk sharing system. First we'll set up Samba, for the sharing within your LAN.
$ sudo apt install samba samba-common-bin
$ sudo nano /etc/samba/smb.conf
[global] # Network workgroup = NASPi interfaces = 127.0.0.0/8 eth0 bind interfaces only = yes # Log log file = /valog/samba/log.%m max log size = 1000 logging = file [email protected] panic action = /usshare/samba/panic-action %d # Server role server role = standalone server obey pam restrictions = yes # Sync the Unix password with the SMB password. unix password sync = yes passwd program = /usbin/passwd %u passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* . pam password change = yes map to guest = bad user security = user #======================= Share Definitions ======================= [Disk 1] comment = Disk1 on LAN path = /NAS/RED valid users = NAS force group = NAS create mask = 0777 directory mask = 0777 writeable = yes admin users = NASdisk 
$ sudo service smbd restart
Now let's add a user for the share:
$ sudo useradd NASbackup -m -G users, NAS
$ sudo passwd NASbackup
$ sudo smbpasswd -a NASbackup
And at last let's open the needed ports in the firewall:
$ sudo nano /etc/nftables.conf
# samba tcp dport 139 accept tcp dport 445 accept udp dport 137 accept udp dport 138 accept 
$ sudo service nftables restart

NextCloud

Now let's set up the service to share disks over the internet. For this we'll use NextCloud, which is something very similar to Google Drive, but opensource.
$ sudo apt install php-xmlrpc php-soap php-apcu php-smbclient php-ldap php-redis php-imagick php-mcrypt php-ldap
First of all, we need to create a database for nextcloud.
$ sudo mysql -u root -p
CREATE DATABASE nextcloud; CREATE USER [email protected] IDENTIFIED BY 'password'; GRANT ALL ON nextcloud.* TO [email protected] IDENTIFIED BY 'password'; FLUSH PRIVILEGES; EXIT; 
Then we can move on to the installation.
$ cd /tmp && wget https://download.nextcloud.com/servereleases/latest.zip
$ sudo unzip latest.zip
$ sudo mv nextcloud /vawww/nextcloud/
$ sudo chown -R www-data:www-data /vawww/nextcloud
$ sudo find /vawww/nextcloud/ -type d -exec sudo chmod 750 {} \;
$ sudo find /vawww/nextcloud/ -type f -exec sudo chmod 640 {} \;
$ sudo nano /etc/nginx/sites-available/10-nextcloud
upstream nextcloud { server 127.0.0.1:9999; keepalive 64; } server { server_name naspi.webredirect.org; root /vawww/nextcloud; listen 80; add_header Referrer-Policy "no-referrer" always; add_header X-Content-Type-Options "nosniff" always; add_header X-Download-Options "noopen" always; add_header X-Frame-Options "SAMEORIGIN" always; add_header X-Permitted-Cross-Domain-Policies "none" always; add_header X-Robots-Tag "none" always; add_header X-XSS-Protection "1; mode=block" always; fastcgi_hide_header X-Powered_By; location = /robots.txt { allow all; log_not_found off; access_log off; } rewrite ^/.well-known/host-meta /public.php?service=host-meta last; rewrite ^/.well-known/host-meta.json /public.php?service=host-meta-json last; rewrite ^/.well-known/webfinger /public.php?service=webfinger last; location = /.well-known/carddav { return 301 $scheme://$host:$server_port/remote.php/dav; } location = /.well-known/caldav { return 301 $scheme://$host:$server_port/remote.php/dav; } client_max_body_size 512M; fastcgi_buffers 64 4K; gzip on; gzip_vary on; gzip_comp_level 4; gzip_min_length 256; gzip_proxied expired no-cache no-store private no_last_modified no_etag auth; gzip_types application/atom+xml application/javascript application/json application/ld+json application/manifest+json application/rss+xml application/vnd.geo+json application/vnd.ms-fontobject application/x-font-ttf application/x-web-app-manifest+json application/xhtml+xml application/xml font/opentype image/bmp image/svg+xml image/x-icon text/cache-manifest text/css text/plain text/vcard text/vnd.rim.location.xloc text/vtt text/x-component text/x-cross-domain-policy; location / { rewrite ^ /index.php; } location ~ ^\/(?:build|tests|config|lib|3rdparty|templates|data)\/ { deny all; } location ~ ^\/(?:\.|autotest|occ|issue|indie|db_|console) { deny all; } location ~ ^\/(?:index|remote|public|cron|core\/ajax\/update|status|ocs\/v[12]|updater\/.+|oc[ms]-provider\/.+)\.php(?:$|\/) { fastcgi_split_path_info ^(.+?\.php)(\/.*|)$; set $path_info $fastcgi_path_info; try_files $fastcgi_script_name =404; include fastcgi_params; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_param PATH_INFO $path_info; fastcgi_param HTTPS on; fastcgi_param modHeadersAvailable true; fastcgi_param front_controller_active true; fastcgi_pass nextcloud; fastcgi_intercept_errors on; fastcgi_request_buffering off; } location ~ ^\/(?:updater|oc[ms]-provider)(?:$|\/) { try_files $uri/ =404; index index.php; } location ~ \.(?:css|js|woff2?|svg|gif|map)$ { try_files $uri /index.php$request_uri; add_header Cache-Control "public, max-age=15778463"; add_header Referrer-Policy "no-referrer" always; add_header X-Content-Type-Options "nosniff" always; add_header X-Download-Options "noopen" always; add_header X-Frame-Options "SAMEORIGIN" always; add_header X-Permitted-Cross-Domain-Policies "none" always; add_header X-Robots-Tag "none" always; add_header X-XSS-Protection "1; mode=block" always; access_log off; } location ~ \.(?:png|html|ttf|ico|jpg|jpeg|bcmap)$ { try_files $uri /index.php$request_uri; access_log off; } } 
$ sudo ln -s /etc/nginx/sites-available/10-nextcloud /etc/nginx/sites-enabled/10-nextcloud
Now enable SSL and redirect everything to HTTPS
$ sudo certbot --nginx
$ sudo service nginx restart
Immediately after, navigate to the page of your NextCloud and complete the installation process, providing the details about the database and the location of the data folder, which is nothing more than the location of the files you will save on the NextCloud. Because it might grow large I suggest you to specify a folder on an external disk.

Minarca

Now to the backup system. For this we'll use Minarca, a web interface based on rdiff-backup. Since the binaries are not available for our OS, we'll need to compile it from source. It's not a big deal, even our small Raspberry Pi 4 can handle the process.
$ cd /home/pi/Documents
$ sudo git clone https://gitlab.com/ikus-soft/minarca.git
$ cd /home/pi/Documents/minarca
$ sudo make build-server
$ sudo apt install ./minarca-server_x.x.x-dxxxxxxxx_xxxxx.deb
$ sudo nano /etc/minarca/minarca-server.conf
# Minarca configuration. # Logging LogLevel=DEBUG LogFile=/valog/minarca/server.log LogAccessFile=/valog/minarca/access.log # Server interface ServerHost=0.0.0.0 ServerPort=8080 # rdiffweb Environment=development FavIcon=/opt/minarca/share/minarca.ico HeaderLogo=/opt/minarca/share/header.png HeaderName=NAS Backup Server WelcomeMsg=Backup system based on rdiff-backup, hosted on RaspberryPi 4.docs](https://gitlab.com/ikus-soft/minarca/-/blob/mastedoc/index.md”>docs)admin DefaultTheme=default # Enable Sqlite DB Authentication. SQLiteDBFile=/etc/minarca/rdw.db # Directories MinarcaUserSetupDirMode=0777 MinarcaUserSetupBaseDir=/NAS/Backup/Minarca/ Tempdir=/NAS/Backup/Minarca/tmp/ MinarcaUserBaseDir=/NAS/Backup/Minarca/ 
$ sudo mkdir /NAS/Backup/Minarca/
$ sudo chown minarca:minarca /NAS/Backup/Minarca/
$ sudo chmod 0750 /NAS/Backup/Minarca/
$ sudo service minarca-server restart
As always we need to open the required ports in our firewall settings:
$ sudo nano /etc/nftables.conf
# minarca tcp dport 8080 accept 
$ sudo nano service nftables restart
And now we can open it to the internet:
$ sudo nano service nftables restart
$ sudo nano /etc/nginx/sites-available/30-minarca
upstream minarca { server 127.0.0.1:8080; keepalive 64; } server { server_name minarca.naspi.webredirect.org; location / { proxy_set_header X-Forwarded-Host $host; proxy_set_header X-Forwarded-Server $host; proxy_set_header X-Forwarded_for $proxy_add_x_forwarded_for; proxy_pass http://minarca; proxy_http_version 1.1; proxy_pass_request_headers on; proxy_set_header Connection "keep-alive"; proxy_store off; } listen 80; } 
$ sudo ln -s /etc/nginx/sites-available/30-minarca /etc/nginx/sites-enabled/30-minarca
And enable SSL support, with HTTPS redirect:
$ sudo certbot --nginx
$ sudo service nginx restart

DNS records

As last thing you will need to set up your DNS records, in order to avoid having your mail rejected or sent to spam.

MX record

name: @ value: mail.naspi.webredirect.org TTL (if present): 90 

PTR record

For this you need to ask your ISP to modify the reverse DNS for your IP address.

SPF record

name: @ value: v=spf1 mx ~all TTL (if present): 90 

DKIM record

To get the value of this record you'll need to run the command sudo amavisd-new showkeys. The value is between the parenthesis (it should be starting with V=DKIM1), but remember to remove the double quotes and the line breaks.
name: dkim._domainkey value: V=DKIM1; P= ... TTL (if present): 90 

DMARC record

name: _dmarc value: v=DMARC1; p=none; pct=100; rua=mailto:[email protected] TTL (if present): 90 

Router ports

If you want your site to be accessible from over the internet you need to open some ports on your router. Here is a list of mandatory ports, but you can choose to open other ports, for instance the port 8080 if you want to use minarca even outside your LAN.

mailserver ports

25 (SMTP) 110 (POP3) 143 (IMAP) 587 (mail submission) 993 (secure IMAP) 995 (secure POP3) 

ssh port

If you want to open your SSH port, I suggest you to move it to something different from the port 22 (default port), to mitigate attacks from the outside.

HTTP/HTTPS ports

80 (HTTP) 443 (HTTPS) 

The end?

And now the server is complete. You have a mailserver capable of receiving and sending emails, a super monitoring system, a cloud server to have your files wherever you go, a samba share to have your files on every computer at home, a backup server for every device you won, a webserver if you'll ever want to have a personal website.
But now you can do whatever you want, add things, tweak settings and so on. Your imagination is your only limit (almost).
EDIT: typos ;)

MAME 0.221

MAME 0.221

Our fourth release of the year, MAME 0.221, is now ready. There are lots of interesting changes this time. We’ll start with some of the additions. There’s another load of TV games from JAKKS Pacific, Senario, Tech2Go and others. We’ve added another Panorama Screen Game & Watch title: this one features the lovable comic strip canine Snoopy. On the arcade side, we’ve got Great Bishi Bashi Champ and Anime Champ (both from Konami), Goori Goori (Unico), the prototype Galun.Pa! (Capcom CPS), a censored German version of Gun.Smoke, a Japanese location test version of DoDonPachi Dai-Ou-Jou, and more bootlegs of Cadillacs and Dinosaurs, Final Fight, Galaxian, Pang! 3 and Warriors of Fate.
In computer emulation, we’re proud to present another working UNIX workstation: the MIPS R3000 version of Sony’s NEWS family. NEWS was never widespread outside Japan, so it’s very exciting to see this running. F.Ulivi has added support for the Swedish/Finnish and German versions of the HP 86B, and added two service ROMs to the software list. ICEknight contributed a cassette software list for the Timex NTSC variants of the Sinclair home computers. There are some nice emulation improvements for the Luxor ABC family of computers, with the ABC 802 now considered working.
Other additions include discrete audio emulation for Midway’s Gun Fight, voice output for Filetto, support for configurable Toshiba Pasopia PAC2 slot devices, more vgmplay features, and lots more Capcom CPS mappers implemented according to equations from dumped PALs. This release also cleans up and simplifies ROM loading. For the most part things should work as well as or better than they did before, but MAME will no longer find loose CHD files in top-level media directories. This is intentional – it’s unwieldy with the number of supported systems.
As usual, you can get the source and 64-bit Windows binary packages from the download page. This will be the last month where we use this format for the release notes – with the increase in monthly development activity, it’s becoming impractical to keep up.

MAME 0.221

MAME 0.221

Our fourth release of the year, MAME 0.221, is now ready. There are lots of interesting changes this time. We’ll start with some of the additions. There’s another load of TV games from JAKKS Pacific, Senario, Tech2Go and others. We’ve added another Panorama Screen Game & Watch title: this one features the lovable comic strip canine Snoopy. On the arcade side, we’ve got Great Bishi Bashi Champ and Anime Champ (both from Konami), Goori Goori (Unico), the prototype Galun.Pa! (Capcom CPS), a censored German version of Gun.Smoke, a Japanese location test version of DoDonPachi Dai-Ou-Jou, and more bootlegs of Cadillacs and Dinosaurs, Final Fight, Galaxian, Pang! 3 and Warriors of Fate.
In computer emulation, we’re proud to present another working UNIX workstation: the MIPS R3000 version of Sony’s NEWS family. NEWS was never widespread outside Japan, so it’s very exciting to see this running. F.Ulivi has added support for the Swedish/Finnish and German versions of the HP 86B, and added two service ROMs to the software list. ICEknight contributed a cassette software list for the Timex NTSC variants of the Sinclair home computers. There are some nice emulation improvements for the Luxor ABC family of computers, with the ABC 802 now considered working.
Other additions include discrete audio emulation for Midway’s Gun Fight, voice output for Filetto, support for configurable Toshiba Pasopia PAC2 slot devices, more vgmplay features, and lots more Capcom CPS mappers implemented according to equations from dumped PALs. This release also cleans up and simplifies ROM loading. For the most part things should work as well as or better than they did before, but MAME will no longer find loose CHD files in top-level media directories. This is intentional – it’s unwieldy with the number of supported systems.
As usual, you can get the source and 64-bit Windows binary packages from the download page. This will be the last month where we use this format for the release notes – with the increase in monthly development activity, it’s becoming impractical to keep up.
