Add a samba user if the same unix user exists

sudo apt install samba 
sudo smbpasswd -a $USER

Smbclient

sudo apt install smbclient

smbclient '\\192.168.1.123\someDir' -c 'prompt OFF;lcd "localDir";mput movie.mp4' -U userName passwd

FTP Client 

ftp -inv ftp.ebi.ac.uk <<EOF
user anonymous {mypassword}
cd pub/databases/msd/sifts/xml
mget 5z*.xml.gz 
bye
EOF

Or

ftp -inv ftp.ebi.ac.uk <<EOF
user anonymous {mypassword}
cd pub/databases/msd/sifts/xml
get 5z8t.xml.gz
get 5z51.xml.gz
get 5zu3.xml.gz
bye

list local dir

!ls

NFS Client

sudo apt install nfs-common
showmount -e 192.168.1.123 
# Export list for 192.168.1.123:
# /mnt/someDir 192.168.1.0/24
mount 192.168.1.123:/mnt/someDir /nfs/general

DHCP Server

  • Assume eth0 is already configured with ip 192.168.3.3/24 (Otherwise dhcpd will fail to start)
  • A dhcp server (dhcpd) can be started for 192.168.3.0/24
sudo apt install isc-dhcp-server
cat << EOF > /etc/dhcp/dhcpd.conf
default-lease-time 600;
max-lease-time 7200;

subnet 192.168.3.0 netmask 255.255.255.0 {
 range 192.168.3.100 192.168.3.200;
 option routers 192.168.3.3;
 option domain-name-servers 8.8.8.8, 8.8.4.4; 
}
EOF
cat << EOF > /etc/default/isc-dhcp-server # specify the interfaces dhcpd should listen to.
INTERFACESv4="eth0"
EOF
sudo systemctl restart isc-dhcp-server.service
  • dhcpd’s messages are being sent to syslog.
  • List dhcpd's users

rsync Server

cat << EOF > /etc/rsyncd.conf
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsync.lock
log file = /var/log/rsync.log
port = 8873

[my_remote_dir]
path = /tmp/rsync
comment = Rsync files
timeout = 300
read only = false
EOF
rsync --daemon
rsync -azP /local_dir/ rsync://host:port/my_remote_dir/
  • Rsync recurrently
rsync -azv --delete /mnt/e/ /mnt/h/
  • Folder exclusion (you cannot exclude '/var/www/html/software/docker' because there is no '/var/www/html/software/docker' under '/var/www')
rsync -rtP --exclude 'www/html/software/docker' /var/www /media/aaa/AutoChem_Backup/

Email Server (Not working for AWS Host. Additional configuration is needed for AWS)

  1. Add a MX record to DNS registrar
Name   Type    Data

Let's Encrypt

Installation

sudo apt update -y && sudo apt install -y python3-certbot-apache
sudo certbot --apache --agree-tos --non-interactive --email your_email_address -d your_domain_name

Renew cert

sudo letsencrypt renew

Location of cert

  • Public cert: /etc/letsencrypt/live/your_domain_name/fullchain.pem
  • Private key: /etc/letsencrypt/live/your_domain_name/privkey.pem

What are these PEM file

  • cert.pem contains the server certificate by itself.
  • chain.pem contains intermediate certificates. Some webservers like separated certficate files.
  • fullchain.pem contains cert.pem and chain.pem. Some webservers like unseparated certficate files.
  • private.pem counterpart of the server certificate
