Have you checked if the snort user has permissions to write to the output directory?

Are the logs created when you run snort as root?

Subject: [Snort-users] Snort read file to generate u2 logs.

I'm using Snort read a file to generate alerts with the following command:

sudo snort -q -u snort-user -g snort-group -c /etc/snort/snort.conf -r file-name

Snort can generate alerts but doesn't create u2 log files, neither other output (e.g., csv) , although the same snort.conf file will generate both alerts and .u2 files.) Wondering if there's a way Snort can generate specified format logs when reading a file.
