# Fail2ban setup to block users after failed login attemts
|
||
|
|
|
||
|
|
**Remember that fail2ban is powerful and can cause lots of issues if you do it incorrectly, so make
|
||
|
|
sure to test this before relying on it so you don't lock yourself out.**

Gitea returns an HTTP 200 for bad logins in the web logs, but if you have logging options on in
|
||
|
|
`app.ini`, then you should be able to go off of log/gitea.log, which gives you something like this
|
||
|
|
on a bad authentication:
|
||
|
|
|
||
|
|
```log
|
||
|
|
2018/04/26 18:15:54 [I] Failed authentication attempt for user from xxx.xxx.xxx.xxx
|
||
|
|
```
|
||
|
|
|
||
|
|
So we set our filter in `/etc/fail2ban/filter.d/gitea.conf`:
|
||
|
|
|
||
|
|
```ini
|
||
|
|
# gitea.conf
|
||
|
|
[Definition]
|
||
|
|
failregex = .*Failed authentication attempt for .* from <HOST>
|
||
|
|
ignoreregex =
|
||
|
|
```
|
||
|
|
|
||
|
|
And configure it in `/etc/fail2ban/jail.d/jail.local`:
|
||
|
|
|
||
|
|
```ini
|
||
|
|
[gitea]
|
||
|
|
enabled = true
|
||
|
|
port = http,https
|
||
|
|
filter = gitea
|
||
|
|
logpath = /home/git/gitea/log/gitea.log
|
||
|
|
maxretry = 10
|
||
|
|
findtime = 3600
|
||
|
|
bantime = 900
|
||
|
|
action = iptables-allports
|
||
|
|
```
|
||
|
|
|
||
|
|
Make sure and read up on fail2ban and configure it to your needs, this bans someone
|
||
|
|
for **15 minutes** (from all ports) when they fail authentication 10 times in an hour.
|
||
|
|
|
||
|
|
If you run Gitea behind a reverse proxy with nginx (for example with docker), you need to add
|
||
|
|
this to your nginx configuration so that IPs don't show up as 127.0.0.1:
|
||
|
|
|
||
|
|
```
|
||
|
|
proxy_set_header X-Real-IP $remote_addr;
|
||
|
|
```
