NTP Client vulnerable to buffer overflow?

I have a web server behind RoS 3.22. The router performs NAT and passes port 80 and port 443 web traffic along only. The web server is also protected by its own software firewall. A vulnerability scan was performed by ComplyGuard as part of a PCI compliance check for the web server. This turned up t...

Dude Agents on RB433 Lose Configuration upon PF

We have several version 3.5 Dude Agents deployed in a distributed system (one per POP). From time to time, they appear to disconnect from the main Dude server. In each case, I have found that the Dude Agent configuration is lost. After a power failure for example. I once thought that a recycle of th...

Re: HA for PPPoE/FreeRadius

Hope it is that easy! I did not see a way to specify more than one IP from Winbox -> Radius menu. Maybe it can be done from command-line and no GUI? I am using ROS 3.2...

Will try this evening...
Thanks!

HA for PPPoE/FreeRadius

We have multiple POP's pointing to a single FreeRadius server for PPPoE auth/accounting. The Winbox for ROS seems to allow for one Radius server IP to be specified only and does not seem to accept DNS name. The problem to solve is that Radius becomes a single point of failure for all pops. To begin ...

Re: RADIUS Client Timeouts on 3.22 400 & 500 series via PPPoE

Just to rule that out, I'll run NMAP against it tonight. NTRadPing worked fine and also [oddly] the MT did authenticate on two occasions.

Thanks for the input!

PPPoE -How best to monitor equip between PPPoE Server & CPE?

I have recently deployed PPPoE on my latest MikroTik (3.x) and have had good success thus far with it. A RB is acting as the concentrator at a repeater site. The WAN port backhauls to our T3. In this case, Motorola Canopy AP's and SU's are in between the PPPoE Server Port and the CPE router which in...
