Hello Javier, I've attached the output. I have purged snort, then re-installed it and can reproduce. The funny thing is that snort is started twice during the installation (so i have to kill it twice). > Also please tell me whether you have a file named > /etc/snort/snort.common.parameters or > a file /etc/default/snort in your system (or both) and provide the contents > of those files.
