Zabbix How-To

For notes / info please scroll to bottom of page. Most commands can just be copy-pasted.

Create a new jail

# Finch users should update to get the latest fixes
[ "$(echo "$(finch --shortver) >= 1.25" | bc)" = 1 ] || sudo finch update -y
sudo finch chroot

# Read the page "jail-ip-addresses" before choosing a jail IP address
jail_ip="192.168.1.212"

# Set a matching ip address for the jail's 'lo0' ifconfig device (for localhost)
jail_loopback="lo0|127.0.0.212"

# Give an appropriate server name to your jail
jailname="zabbix"

# Create a basic jail, with local console access
qjail create -4 "$jail_ip,$jail_loopback" "$jailname"

# Enable unix sockets
qjail config -k "$jailname"

# Enable sysvipc semaphores
qjail config -y "$jailname"

Login to the jail

# Start the jail
qjail start "$jailname"

# Login to our new jail as root
qjail console "$jailname"
