Recently I have a problem with Gitlab: My colleague had mistakenly typed wrong password multiple times on Gitlab login and all of us cannot access Gitlab because of IP ban.

It take a while for me to find out how to remove the banned IP on Gitlab. So I write it here for anyone can save their time:

Firstly, open redis client:

sudo /opt/gitlab/embedded/bin/redis-cli -s /var/opt/gitlab/redis/redis.socket

List the item with key contains “rack”:

redis /var/opt/gitlab/redis/redis.socket> KEYS *rack*

The result may like this:

1) cache:gitlab:rack::attack:allow2ban:ban:1.2.3.4

You can remove the ban using DEL command:

redis /var/opt/gitlab/redis/redis.socket> DEL “cache:gitlab:rack::attack:allow2ban:ban:1.2.3.4”

When my script finally worked

When I am asked to continue work of a newbie colleague

When I’m told that my code is broken in production

When a newbie suggests to add a new feature to project

When a bug goes unnoticed during a presentation
