## Configure fail2ban for Gitblit-SSH

This procedure uses fail2ban.

First, create a new filter file `gitblit.conf` in filter directory (Debian/CentOS: `/etc/fail2ban/filter.d/`) or into `filter.conf` file. Here is an example:

    [Definition]
    failregex =  Failed login attempt for .+, invalid credentials from <HOST>\s*$
                 could not authenticate .*? \(/<HOST>:[0-9]*\) for SSH using the supplied password$
    ignoreregex =

Then edit `jail.conf` to add "gitblit" service (Debian: `/etc/fail2ban/jail.conf`). For example:

    [gitblit]
    enabled = true
    port = 443,29418
    protocol = tcp
    filter = gitblit
    logpath = /var/log/gitblit.log

Reload fail2ban config to apply (`fail2ban-client reload`).

Check the status of the gitblit fail2ban jail with `fail2ban-client status gitblit`
