I was tarted few days ago with a rb750 (1st gen), now i bought the rb750gr3. I have the router online and all configuration was imported and with a few corrections all works ok.
But i was trying to “play” with dude server. Im not a MK expert, but i see its a networking monitoring server/agent. The problem is, because the low disk space on this model, i try to use a 64Gb microsd class 10, and doesen’t work.
As i can see, the MK fails when try to format the sd. If I insert the same sd card into a notebook or dektop PC, i can format, write, read, all perfect. Now, in the MK, I insert the sd card, and i can read and drop files. But when i try to format fails again (ext3 or fat32 its the same). I can see error 6 when I eject the sd by command line and type the format command. When error appears, i lost the disk. I have to re insert the sd many times until the MK can read again it. But any format is recognized.
Anyone have this issue ? its a HW problem? i just upgraded firmare to 6.46.6 version but the problem remains. So i disabled dude package by now.
Maybe is for another topic, but i have some FW rules to add to a list called “blocked” to the IP from try to snif some ports. I was collecting like 20-30 IP addresses by day, but now I have more than 1000 in 5 hours. I must be worried? I copied a script to convert that dynamic IP to static ones,… but can this method tie down my router? by filling the memory with thousands of static IPs?
I dont have inside knowledge on how MikroTik processes this but there has to be an upper bound on performance here. Assuming IPs being dynamic you could be filling up that list way past thousands and into millions if not billion. A scan of such as list, given that MikroTik is not a database has to take time.
Found my mistake! I was adding to blocked list all hits to port 80 and 22,… but i have disabled http (inside and outside), and enabled https and ssh only from my lan, and the ports are changed, so i disabled the ports 22 and 80 scanning from outside, it have no sense.
