Intrusion Detection and Prevention / Suricata failing to start using LAN on ZimaBoard

« on: May 22, 2024, 08:16:18 pm »

Bit of a really strange one going on here that I don't even know how to debug.

Recently swapped my large 1u rack for a small ZimaBoard in an attempt to generate less heat in my rack (I don't have the option of proper ventilation for it). I previously had Suricata running without issue (to my knowledge, can't check easily now) but it doesn't seem happy binding to the LAN interface on this board. I'd understand this more if it didn't successfully start when using the WAN port.

The exact exit error is:

Code: [Select]

[101841] <Error> -- opening devname netmap:re0/R failed: Invalid argument
Interface specs

Code: [Select]

# pciconf -lv | grep -A1 -B3 network

If anybody has any idea why re1 works but re0 doesn't it would be most appreciated, thanks
