* set small `bantime` (e. g. 1 second) to this "jail" (otherwise no "ban" action will be executed in this time, because "already banned" occurs), e. g. `bantime = 1`
* you need to specify only `actionban` parameter in your custom action file:
```INI
actionban = /user/bin/ids-attack.sh '<fid>'
actionban = /user/bin/ids-attack.sh "<fid>"
```
* `actionban` script will be executed as root (or with user, fail2ban running), so use `su` if other/restricted user needed;
- set `usedns`, `ignoreip`, `ignorecommand` as suggested above, otherwise you can get error by comparison with empty/illegal host (that will be found by "failure");
