Hello dear Proxmox Community,

my issue is that iam afraid of customers starting outgoing DoS atacks because of traffic wich is verry expensive at my current datacenter (1Tb = 18€ | 22,36$).
This is why iam struggling with those customers all over the time, wich brings me to the thaugt to limit the Network speed, but this in my eyes also not a long-term solution because i sell my servers with the promiss of a 1 gbit Uplink.

So i wanted to ask if someone knows a monitoring software wich scans the network interface's or Ip's and stops the server if it detects an outgoing attack.

All other solutions would be also verry apreciated.

ps Sorry for any mistakes, english is not my mother language and I'm only 16 Years old!

best regards

Hi @Nicolas Janzen ,

One simple option, is to use monit on your PMX node/s. Monit can monitorize many ethernet metrics(packates number in/out, bandwith, total up/down and so on). So on the desired level of let say X pcs/time monit can run any custom script, like disconnect tapX interface, or whatever it is OK for you.

Have a nice day for any young admin like you ;)
