The problem with that script is the function :toarray,
:set noiphostarray [:toarray $noiphost]
That line produces a malfunction of the script because it never saves the value of the current IP address in var $previousIP, so the script is constantly updating the IP address when it is not necessary because it hasn’t changed.
Here is my debugged script working on RouterOS version 6.7:
# No-IP automatic Dynamic DNS update
#--------------- Change Values in this section to match your setup ------------------
# No-IP User account info
:local noipuser "YOUR-NO-IP-USERNAME";
:local noippass "YOUR-NO-IP-PASSWORD";
# Set the hostname or label of network to be updated.
:local noiphost "YOUR-NO-IP-HOSTNAME";
# Change to the name of interface that gets the dynamic IP address
:local inetinterface "INTERFACE-THAT-YOU-WANT-TO-UPDATE-IP-ADDRESS";
#------------------------------------------------------------------------------------
# No more changes need
:global previousIP;
:if ([/interface get $inetinterface value-name=running]) do={
# Get the current IP on the interface
:local currentIP [/ip address get [find interface="$inetinterface" disabled=no] address];
# Strip the net mask off the IP address
:for i from=( [:len $currentIP] - 1) to=0 do={
:if ( [:pick $currentIP $i] = "/") do={
:set currentIP [:pick $currentIP 0 $i];
}
}
:if ($currentIP != $previousIP) do={
:log info "No-IP: Current IP $currentIP is not equal to previous IP, update needed";
:set previousIP $currentIP;
:local url "http://dynupdate.no-ip.com/nic/update\3Fmyip=$currentIP";
:log info "No-IP: Sending update for $noiphost";
/tool fetch url=($url . "&hostname=$noiphost") user=$noipuser password=$noippass mode=http dst-path=("no-ip_ddns_update-" . $host . ".txt")
:log info "No-IP: Host $noiphost updated on No-IP with IP $currentIP";
} else={
:log info "No-IP: Previous IP $previousIP is equal to current IP, no update needed";
}
} else={
:log info "No-IP: $inetinterface is not currently running, so therefore will not update.";
}
Since I had some problem while updating, I decide to modify this script setting previousIP as a local variable with its IP resolved by DNS:
:local previousIP [:resolve "$noiphost"];
so this is the updated script:
# No-IP automatic Dynamic DNS update
#--------------- Change Values in this section to match your setup ------------------
# No-IP User account info
:local noipuser "your@email.com"
:local noippass "yourpassword"
# Set the hostname or label of network to be updated.
# Hostnames with spaces are unsupported. Replace the value in the quotations below with your host names.
# To specify multiple hosts, separate them with commas.
:local noiphost "yourname.ddns.net"
# Change to the name of interface that gets the dynamic IP address
:local inetinterface "yourinterface"
#------------------------------------------------------------------------------------
# No more changes need
#:global previousIP;
:if ([/interface get $inetinterface value-name=running]) do={
# Get the current IP on the interface
:local currentIP [/ip address get [find interface="$inetinterface" disabled=no] address];
# Strip the net mask off the IP address
:for i from=( [:len $currentIP] - 1) to=0 do={
:if ( [:pick $currentIP $i] = "/") do={
:set currentIP [:pick $currentIP 0 $i];
}
}
:local previousIP [:resolve "$noiphost"];
:log info "DNS IP: $previousIP, interface IP: $currentIP";
:if ($currentIP != $previousIP) do={
:log info "No-IP: Current IP $currentIP is not equal to previous IP $previousIP, update needed";
# :set previousIP $currentIP;
:local url "http://dynupdate.no-ip.com/nic/update\3Fmyip=$currentIP";
:log info "No-IP: Sending update for $noiphost";
/tool fetch url=($url . "&hostname=$noiphost") user=$noipuser password=$noippass mode=http dst-path=("no-ip_ddns_update-" . $host . ".txt")
:log info "No-IP: Host $noiphost updated on No-IP with IP $currentIP";
} else={
:log info "No-IP: Previous IP $previousIP is equal to current IP, no update needed";
}
} else={
:log info "No-IP: $inetinterface is not currently running, so therefore will not update.";
}
This Mikrotik Noip update script works on 6.27 and it survived an upgrade to 6.34.1
You still need to setup the system scheduler just change the on-event=to match the name of the script
/system scheduler add comment=“Update No-IP DDNS” disabled=no interval=5m
name=no-ip_ddns_update on-event=no-ip_ddns_update policy=read,write,test
I noticed the same thing since June 2016. I got email’s “Please confirm your hostname now or it will be deleted”. Nothing have been changed in script.
Now I have 6.35 on Mikrotik. Any solutions?
