# Option: logtarget
# Notes.: Set the log target. This could be a file, SYSLOG, STDERR or STDOUT.
# Only one log target can be specified.
# If you change logtarget from the default value and you are
# using logrotate -- also adjust or disable rotation in the

logtarget = /var/log/fail2ban.log
# Option: socket
# Notes.: Set the socket file. This is used to communicate with the daemon. Do
# not remove this file when Fail2ban runs. It will not be possible to

pidfile = /var/run/fail2ban/fail2ban.pid
# Options: dbfile
# Notes.: Set the file for the fail2ban persistent data to be stored.
# A value of ":memory:" means database is only stored in memory
