I've got this script from a search but also no email sent when a new device connected to network

I put it in dhcp server alert with default settings of new alert

Code: Select all

:local recipient "someemail@soemserver.com"
/ip dhcp-server lease
:if ($leaseBound = 1) do={
	:do {
		:tool e-mail send to=$recipient subject="DHCP Address Alert [MAC: $leaseActMAC]" body="The following MAC address [$leaseActMAC] received an IP address [$leaseActIP] from the DHCP Server [$leaseServerName]"
		:log info "Sent DHCP alert for MAC $leaseActMAC"
	} on-error={:log error "Failed to send alert email to $recipient"}}

there is no log entry

I think the event didn't fire and the code never executed

This should go in the script box of the dhcp-server you want it to run on - not in the alerts tab.

Nice Addition to the script

add filter rule to block mac address from using internet

Code: Select all

:local recipient "someemail@server.com"
/ip dhcp-server lease
:if (($leaseBound=1) && ([/ip dhcp-server lease find where dynamic mac-address=$leaseActMAC]!="")) do {
	:do {
		:tool e-mail send to=$recipient subject="DHCP Address Alert [MAC: $leaseActMAC]" body="The following MAC address [$leaseActMAC] received an IP address [$leaseActIP] from the DHCP Server [$leaseServerName]"
		:log info "Sent DHCP alert for MAC $leaseActMAC"
		
		/ip firewall filter
               add chain=forward src-mac-address=$leaseActMAC action=drop
	} on-error={:log error "Failed to send alert email to $recipient"}
	
}

a simple alteration to the script

the previous script sends an email when ever a new devices connected to router static or dynamic

in my situation I need to know only dynamic ones because the static ones in known to me

this modification sends only dynamic ip addresses

Code: Select all

:local recipient "someemail@server.com"
/ip dhcp-server lease
:if (($leaseBound=1) && ([/ip dhcp-server lease find where dynamic mac-address=$leaseActMAC]!="")) do {
	:do {
		:tool e-mail send to=$recipient subject="DHCP Address Alert [MAC: $leaseActMAC]" body="The following MAC address [$leaseActMAC] received an IP address [$leaseActIP] from the DHCP Server [$leaseServerName]"
		:log info "Sent DHCP alert for MAC $leaseActMAC"
	} on-error={:log error "Failed to send alert email to $recipient"}
}

Anyone knows how to send email only if a new device connected.
I mean, if the "lease time" is not over yet, then don't send email

:global reportedMacs;
:if (:typeof[$reportedMacs] = "nil") do={
  :global reportedMacs [ :toarray "" ]
}

:local recipient "someemail@server.com"

/ip dhcp-server lease
:if (($leaseBound=1) && ([:type [:find $reportedMacs $leaseActMAC]]="nil") && ([/ip dhcp-server lease find where dynamic mac-address=$leaseActMAC]!="")) do={
	:do {
                :local leaseHostname $"lease-hostname"
		:tool e-mail send to=$recipient subject="[MikroTik] DHCP Address Alert [MAC: $leaseActMAC]" body="MAC:  $leaseActMAC\nIP:   $leaseActIP\nHost: $leaseHostname\nDHCP: $leaseServerName\n\n-- \nRouterOS"
		:log info "Sent DHCP alert for MAC $leaseActMAC"
                :set reportedMacs ( $reportedMacs, $leaseActMAC );
	} on-error={
                :log error "Failed to send alert email to $recipient"}
        }
