You can run multiple instances of Suricata on a single machine if you’d like.
Both the configuration file and the logging directory can be set on the command line:
suricata -c /path/to/configuration-file -l /path/to/logging-directory
You can also specify the NIC interface:
suricata -c /path/to/configuration-file -l /path/to/logging-directory --af-packet=enp3s0
Section 10.4 is for Suricata’s multi-tenancy support. What commands aren’t working as expected?
