Hi,<br>Might be a bit late, but just to clarify - <br>at the moment it appears we have a problem/bug of calculating MD5s in demon mode ( -D ), that problem does NOT exist if you run Suricata not in demon mode (ex: suricata -c /etc/suricata/suricata.yaml -i eth0 )<br>
<br>If you would like to calculate just MD5s for everything (without any rules for the files themselves) - please enable only the JSON output, with forced MD5s and disable file-store, like this :<br>(in suricata.yaml)<br>
<br><blockquote> - file-store:<br> <b>enabled: no </b> # set to yes to enable<br> log-dir: files # directory to store the files<br> force-magic: yes # force logging magic on all stored files<br> force-md5: yes # force logging of md5 checksums<br>
#waldo: file.waldo # waldo file to store the file_id across runs<br><br> # output module to log files tracked in a easily parsable json format<br> - file-log:<br> <b> enabled: yes</b><br> filename: files-json.log<br>
append: no<br> #filetype: regular # 'regular', 'unix_stream' or 'unix_dgram'<br><br> force-magic: yes # force logging magic on all logged files<br> <b>force-md5: yes</b> # force logging of md5 checksums<br>

</div>Hah! So that I'm not just adding adding noise to your mailing list, I'll ask a question too. :)<br>
<br>
Do you have any measurements that show how much of a performance impact enabling MD5 calculation adds? It's a global setting too, right (all on or all off)?<br>
