Update and align Gitea and Gogs docs

[MichaIng]

I almost went crazy with the Gitea systemd Fail2Ban integration: What journalctl -u gitea does not show, but only debugging like

fail2ban-regex --print-all-missed "systemd-journal" gitea
fail2ban-regex -l heavydebug "systemd-journal" gitea

reveals: Gitea logs color codes to the console and while journalctl does not show them, they are actually there, and Fail2Ban parses them. Hence the extended regex compared to when using file logging:

failregex = Failed authentication attempt for \x1b\[1m.+\x1b\[0m from \x1b\[1m<HOST>:\d+\x1b\[0m:

Sadly Gogs does not log failed login attempts at all, hence no Fail2Ban integration possible.

Maybe we can use docker logs to get the fail logger?

I mean for gogs!

[MichaIng]

Not sure what you mean. Our Gogs implementation does not use Docker, logs can be reviewed via:

journalctl -u gogs

and plain text files in

/var/log/gogs
