HOW TO SETUP ZENCASH SECURE/SUPER NODE ON UBUNTU 16.04 SERVER

in #zencash6 years ago (edited)

########################################

DOMAIN CONFIG

########################################

Set your domain with A records on ipv4 and with AAAA records on ipv6


########################################

WALLET

########################################


I use swing wallet

Create new transparent address and send 42 zen for secure node or 500 for supernode


########################################

SECURE THE SERVER

########################################


- Change ssh port


vim /etc/ssh/sshd_config

change 22 with another port like 32

/etc/init.d/ssh restart


- Config Firewall


ufw default allow outgoing
ufw default deny incoming
ufw allow 32/tcp
ufw limit 32/tcp
ufw allow http/tcp
ufw allow https/tcp
ufw allow 9033/tcp
ufw logging on
ufw enable


- Disable ping


vim /etc/sysctl.conf


#####################

net.ipv4.icmp_echo_ignore_all =1 

#####################


sysctl -p


vim /etc/rc.local


##########################################

#Load kernel variables from /etc/sysctl.d

/etc/init.d/procps restart

exit 0

##########################################


- Install Denyhost


apt install denyhosts
vim /etc/denyhosts.conf

insert on the top

#############################

BLOCKPORT = 32

#############################


and change this to 3 failed login


#############################

DENY_THRESHOLD_ROOT = 3

DENY_THRESHOLD_RESTRICTED = 3

#############################


systemctl restart denyhosts.service
systemctl enable denyhosts.service


- Create swap if necessary (ram+swap 6gb total for secure node, 8gb for supernode)


fallocate -l 2G /swapfile

chmod 600 /swapfile

mkswap /swapfile

swapon /swapfile

cat <<EOF >> /etc/fstab

/swapfile none swap sw 0 0

EOF

cat <<EOF >> /etc/sysctl.conf

vm.swappiness=10

EOF
