Bandwith problem


after changing the internet provider we have a bandwith of 430 mbit/s instead of 50 mbit/s before. Unfortunately it seems that the NS gateway is not capable to handle this speed. A client computer gets not more than about 100 mbit/s at maximum. I tried the connect with pfsense as gateway and it works like it should. Any ideas, what slows down the traffic? It would be a pity if I had to say good bye to Nethserver.


Here we have identified snort as a potential culprit:

Are you using snort? Could you try to disable it?

Hi Rasi,
Is all your infrastructure Gigabit ready ?

  • Nics in the NS (Red/Green) are Gbit?
  • Switch is Gigabit ?
  • Nic in the client is Gigabit?

Also, a lot of the speed value is determined by the type of cable used, but i do not think this is the case.

Take note that some network cards work often at 100 mbps even if they are Gbit. (usually a driver update is required)
I can say that NS is capable by default of Gigabit transfer.

Indeed, the problem comes from snort. Thanks for the hint.
But is it safe to keep snort disabled on the gateway? Are there alternatives?

snort :mask: :…

try with suricata :slight_smile:

mutithread support and much better performance… :slight_smile:

whold be great change snort with suricata in nethserver as IPS/IDS :thinking:
