Tip of the day

Need a wireless bridge between two buildings or a quick backhaul link? Have a pair of RouterBoard 411's with their original Level 3 license lying around? Then great, you have exactly what you need to build a point to point link. "What? I thought I needed a level 4 license for one of the boards to be an access point? The level 3 license won't let you use "ap-bridge" mode." You are correct! However, for a single client point to point, you can use "bridge" mode on the wireless card that will act as the AP end of the link. In "bridge" mode (as opposed to "ap-bridge") the AP acts as a normal AP but will only allow one client to associate. The link can still be routed or bridged in "bridge" mode, the difference is only the number of clients it will support.

MikroTik User Manager Automatic Rate Limits

Usermanager is MikroTik's version of radius and is a great way to centralize AAA on your network. In addition, it also has facility to allow users to buy credits on your network through hotspot, however, the only limitation it can automatically create is a time limitation. You can create packages that allow access for a day, week, month, etc., but in order to set a rate limit for that customer and their package, you have to manually make that change to the user in Usermanager.

I needed a way to automatically accomplish this so I enlisted the help of my script guru, Andrew Cox. Although I have never met Andrew in person, I can tell you he is a bright guy who is one of the few people I know that truly speaks MikroTik's scripting language. As usual, Andrew rose to the challenge and wrote a few lines of code that function perfectly.

A few notes, first the script uses the user property "credit-price" to determine which package the customer purchased, therefore, you need to have unique prices for each rate limit. For example, if the Gold package is 128k/64k and costs $25, then users that buy the 64k/64k package that costs $25 will get the same rate limit. In this example, just change the price slightly on one of the packages and it will work correctly. For example, make the 128k/64k package $19.95 or something similar.

So, here is the code, past it into a new script item through Winbox, set the scheduler to run it once every minute or so and you will enjoy the benefits of automatic rate limits with self created user accounts.

#We only check the first 3 characters, this means you can continue to use the comment field for whatever you like so long as you leave the 'RLA' untouched (if present)
:set check [:pick [/tool user-manager user get $counter value=comment] 0 3]
:if ($check="RLA") do={

#Has RLA, rate limit is already set so ignore

} else={
