Indeed, I tried it right after having posted and it worked like a charm :) I didn't have any warnings nor errors during install and fail2ban log is now OK.
The "RANDOM" hack I've seen on forums didn't work for me because fail2ban seems to run /bin/sh and the RANDOM command was not recognized. I'm glad I could find a cooler and cleaner way to fix it :) Mathieu BAUTISTA Sys admin at IRCF www.ircf.fr -- To UNSUBSCRIBE, email to debian-bugs-rc-requ...@lists.debian.org with a subject of "unsubscribe".
