The problem is if the CHR has a non-trial license, there is no way to do this, as the license in the router will not appear in the account, and cannot be added to the account. It definitely will appear in the account. There must have been some unrelated problem that caused you to resolve it this wa...

Question is pretty straightforward - We purchased a Maxxwave Vengeance Router using CHR - it shipped with a P10 license, and we didn't realize this until we deployed it and ran into issues when the total traffic (in and out) exceeded 10 Gbps. We wanted to update the license to P Unlimited, so we co...

You must go into your mikrotik account, then go into your "CHR licenses" menu on the left, find your current installation and click UPGRADE. Then choose the desired level (P-U), then it will ask how you want to pay. You can then select the prepaid key. The problem is if the CHR has a non-...

Well, I grabbed my copy of Learn RouterOS 2nd Ed., and I made some changes in rule order, using Firewall Efficiencies on pg 126-127 as a guide, but I'm still not certain what was happening when the attack was going on that could have overloaded the 72-core CPU... If the router is not configured corr...

We've suffered a few brutal DDoS attacks over the last few days (not all that unusual), but we graph CPU usage on all our Mikrotiks, and the graph showed some CCR1072 routers hitting 100% CPU usage during the attack, even though normal CPU usage is below 10%. We're doing the usual review/audit and u...

I used to be able to find some reliable x86 routers using Mikrotik RouterOS - Baltic had their MAXXWave line, and Titan Wireless had their Mikronoc line, but alas,Titan was bought by ISP Supplies, and no longer makes the Mikronoc routers, and the latest MAXXwave is a VM monstrosity which caused some...

Well, persistence finally paid off - I discovered that the Mtik API interface was properly installed, but there had been some other error (probably type mismatch) preventing my earlier efforts from working. Just to help others in the spot I was in, here's the successful snippet of code: if (Mtik::lo...

OK, so gave up on the Perl approach - successfully got Ruby and the Mtik API interface installed. Successfully connected to a router using the tikcli script... Feed it the following command: /ip/arp/print ?mac-address=00:60:E0:45:CE:AA It spits out the entire 70 item ARP table, not just the one entr...

That sounds great, but... I have tried to install the API (went to http://search.cpan.org/dist/MikroTik-API/ to get the tar.gz file, followed the instructions in the README), but it will not install. "make test" always fails with an "Error: Can't locate object method "get_or_add_...

I am trying to build a Perl script which will grab the IP address associated with a particular MAC address from the ARP table. In the CLI, it's easy: just navigate to /ip arp and run the command below (where $t_mac is the colon-delimited, uppercase MAC address) :put [get [/ip arp find mac-address=$t...

We've had several RB493 units die with the capacitor issue this year, and we are looking to preemptively replace the remaining 493 and 493AH units in our network with 493G units. Here's the question - have those failures been noticed on the 493G at all? It looks like 411AH, various 493's, and 450G's...

multihomed? are the packets coming and going on the same interface? RouterOS will reply with src ip from whatever route it takes, so if you are not using the default gateway you will get no snmp responses from the router (they dont come from the requested ip). i wish you could bind snmp to the loop...

use 5.11 for SNMP, as 5.10 received SNMP changes. Here's an update: This morning, I connected to the other brand-new MikroNOC 8400 with 5.2, with the intent of upgrading this one to 5.11 in hopes that would solve the SNMP problem. Just out of curiosity, before I installed the upgrade, I tried to do...

We just started using a brand-new MikroNOC 8400 with RouterOS 5.2 to replace a very stressed RB493AH running RouterOS 3.30, and I'm encountering the same issue. It won't respond to SNMP queries or walks: "Timeout: No Response from xx.xx.xx.xx." The new router was configured from the backup...
