fail2ban setup

Not sure it goes here, could not find an other place. For anyone that would find this useful 🙂

fail2ban setup on Ubuntu 20.04 LTS Using the scripted install, not sure how it applies for dockerized version but that should not be too different

Create a /etc/fail2ban/jail.d/custom.conf In the default section, add the IPs that should never be blocked then your standard settings for findtime, bantime & maxretry Personnally I use these:

[DEFAULT]
ignoreip = 127.0.0.0/8 <my public IP> <any IP you need here>
findtime = 1h
bantime = 7d
maxretry = 3

Then add this section for wildduck

[wildduck]
enabled  = true
port     = 993,995
filter   = wildduck
logpath  = /var/log/wildduck-server/wildduck-server.log

Then create /etc/fail2ban/filter.d/wildduck.conf

[INCLUDES]
before = common.conf

[Definition]
failregex = \[AUTHFAIL\] .*"_ip":"<HOST>"
ignoreregex =

And restart fail2ban.

OK so I’ve made my very first github contrilb 🙂 If I’ve followed the instructions correctly, you should have received a PR with the document updated.
