Sending your self an e-mail with DSL interface IP address

The goal

The goal is to know yout DSL interface IP address at all time if you need to connect to your MT box for any reason. It is a simple script.

The script

Create a new script with the following source

:global ddnsip
:global ddnslastip
:if ([ :typeof $ddnslastip ] = nil ) do={ :global ddnslastip "0" }
#:log info "v-ddnslastip= $ddnslastip"

:global ddnsinterface
:global ddnssystem ("Version-" . [/system package get system version] )
#:log info "v-ddnssystem= $ddnssystem"

:local int

:foreach int in=[/ip route find dst-address=0.0.0.0/0 active=yes ] do={
  :if ([:typeof [/ip route get $int routing-mark ]] != str ) do={
     :global ddnsinterface [/ip route get $int interface]
#     :log info "v-ddnsinterface= $ddnsinterface"
  }
}


:global ddnsip [ /ip address get [/ip address find interface=$ddnsinterface ] address ]
#:log info "v-ddnsip= $ddnsip"
:if ([ :typeof $ddnsip ] = nil ) do={
   :log info ("DDNS: No ip address present on " . $ddnsinterface . ", please check.")
} else={

  :if ($ddnsip != $ddnslastip) do={
    :global datum [/system clock get date]
    :global vrijeme [/system clock get time]
    /tool e-mail send from=from@email.here.com to=to@email.here.com subject="DSL IP $datum $vrijeme" body="DSL IP $ddnsip" server=mail.server.ip.address
    :log info "DDNS: Sending UPDATE!"
    :global ddnslastip "$ddnsip"
  } else={
#    :log info "DDNS: No update required."
  }
}

The schedule

Create a schedule that runs the script every ten or so minutes and save.

add comment="" disabled=no interval=10m name=schedule1 on-event="sys scr run 4" start-date=may/15/2008 start-time=09:00:00

Replace the script number with the correct number.

Since it is a simple script, you can schedule it to run every minute.
