Auto upgrade script V3.x

One little script to upgrade RrouterBoards automatically.

• ) fetch file from main router containing latest ROS version number;
• ) get currently running version number;
• ) extract minor and major version numbers and compare them;
• ) if version fetched from main router is newer then download combined package directly from mikrotik.com
• ) reboot.

At first you should create file containing newest version number on main router.

/file print file="latestVer";
/file set latestVer.txt content="3.3";

Now we are ready to run scripts on other routers:

# newest version
:local lMajor;

# current version
:local vMajor;
:local vMinor;


# detect platform
:local platform [/system resource get architecture-name];

:local myVer [/system resource get version];

# fetch latest version
/tool fetch address="172.16.0.1" path="currentVer.txt" user="admin" password="" mode=ftp;
:local lVer [/file get currentVer.txt content];

:for i from=0 to=([:len $myVer] - 1) do={  
	:if ( [:pick $myVer $i] = ".") do={ 
		:set vMajor [:tonum [:pick $myVer 0 $i]]; 
		:set vMinor [:tonum [:pick $myVer ($i + 1) [:len $myVer]]] ;
	}
}

:for i from=0 to=([:len $lVer] - 1) do={  
	:if ( [:pick $lVer $i] = ".") do={ 
		:set lMajor [:tonum [:pick $lVer 0 $i]]; 
		:set lMinor [:tonum [:pick $lVer ($i + 1) [:len $lVer]]] ;
	}
}

:if ($vMajor < 3) do={
	:log warning "oOops:( /tool fetch supported only on 3.x )";
} else={ 
	:if (($vMajor = $lMajor) && ($vMinor < $lMinor)) do={
		:local pckgName ("routeros-" . $platform . "-" . $lMajor . "." . $lMinor . ".npk");
		/tool fetch address="www.mikrotik.com" host="www.mikrotik.com" mode=http path="download/$pckgName";
		/system reboot;
	}
}

Add scheduler to run this script, for example once in 24h (or whatever interval you like).
